Material and Method: We identifed 36 glioneuronal tumors with Gereç ve Yöntem: Çalışmamıza uCsF Patoloji Anabilim Dalı malignant histological features among the departmental archives and arşivinden derlediğimiz malign histolojik özellikler gösteren 36 neuropathology consultation fles of the authors. Results: based on their pathological features, we divided the study Bulgular: Olgular histopatolojik özelliklerine göre üç kategoriye group into three histologically distinct categories:) glioneuronal ayrıldı:) malign glial komponent içeren glionöronal tümörler tumors with a malignant glial component (anaplastic gangliogliomas); (anaplastik gangliogliomlar); 2) malign nöronal/nöroblastik 2) glioneuronal tumors with a malignant neuronal/neuroblastic komponent içeren glionöronal tümörler; 3) hem glial hem de component; 3) glioneuronal tumors with both malignant neuronal nöronal komponenti malign olan glionöronal tümörler. All tumors occurred in a younger age group radyolojik olarak iyi sınırlı, kistik ve solid komponent içeren, değişken compared to glioblastomas and appeared radiologically well-defned, kontrast madde tutulumu gösteren ve glioblastoma oranla daha genç cystic and solid with variable contrast enhancement.

The biological behavior or series of glioneuronal tumors that were radiologically radiological features of gangliogliomas have been well well-circumscribed and were amenable to gross total recognized, but the anaplastic variant is poorly understood resection (9). Malignant glial components conformed to the “malignant glioma with neuroblastic or PnEt-like elements” anaplastic astrocytoma or glioblastoma multiforme, while (3). Tese neoplasms are referred to as GbM-PnEt and malignant neuronal components were consistent with exhibit genetic alterations typical of glioblastomas in their neuroblastoma, primitive neuroectodermal tumor (PnEt), glial components and typical of embryonal tumors in their or ganglioneuroblastoma (3). The glial tumors with greater than 90% small, undiferentiated cells component of these tumors is typically a difuse high grade. Formalin-fxed, parafn Glioneuronal tumors with malignant neuronal/neuroblastic embedded tissue was used for routine histological and component (category 2); 3 tumors with histologically immunohistochemical studies. The mean ages for the categories were 29, 47, usA), neuroflament protein (prediluted Cellmark, usA), and 30 years, respectively. Glioneuronal tumors with malignant glial avidin-biotin-peroxidase method with appropriate positive components (anaplastic gangliogliomas; 15 tumors) and negative controls. Anti-Hu immunohistochemical Tere were seven females and eight males in this group with staining procedure was performed using the method a mean age of 29 years (range 6-63). All tumors had benign or low Statistical Analyses gradeganglionic/neuronalcomponentanddemonstratedan infltrating high grade glial component. Eleven of the tumors All statistical analyses were performed using the sPss in this category had a synchronous benign ganglioglioma sofware package (sPss bAsE Version 8 for Windows with microscopically distinct from the malignant glioma. The granular bodies, perivascular infammatory infltrates and non-parametric Mann-Whitney and Kruskal-Wallis tests hyalinized vessels mature neuronal/ganglionic cells typical were used to determine diferences among tumor categories. The well were calculated using Kaplan-Meier curves, and standard diferentiated neuronal components displayed focal strong errors for curves were calculated using Greenwood’s synaptophysin, chromogranin and anti-Hu positivity on formula (22). Dystrophic calcifcations were diagnosis and frst clinical evidence of tumor recurrence. The malignant components had Os was defned as the time interval between diagnosis and hyperchromatic pleomorphic cells with mitotic fgures death. Comparison between curves survival was made by and conspicuous vascular proliferation (Figure 2b), and using the log-rank test. Other presenting symptoms were seizures (4 cases), limb weakness (2 cases), visual disturbance (7 cases), gait disturbance (5 cases), lethargy (5 cases), dizziness, nausea/vomiting and loss of consciousness. Tumor Categorization Figure 1: Location of histological categories of malignant glioneuronal tumors. The gray circles denote category, white The tumors were categorized into three morphologically circles denote category 2, and patterned circles denote category distinct categories based on the malignant component: 3 tumors. The malignant glial one case, small cell clusters with better diferentiated small components were positive for glial fbrillary acidic protein neuronal populations resembling mature small neurons in all cases where the staining was performed (Figure 2D). Focal PnEt-like areas were seen in one case in immunohistochemical staining for proliferation marker this group. Tree of the cases had microscopically distinct Ki-67 (Mib) in six tumors demonstrated approximately regions that fulflled the diagnostic criteria for grade i 0% labeling index in the malignant glial component. Glioneuronal tumors with malignant neuronal in patient # 6, a tumor had been removed from the components (4 tumors) cerebellum approximately 46 years ago. Even though the Tere were three females 5, 59, and 69 years of age and clinical diagnosis was pilocytic astrocytoma, no pathology one male at the age of 43 in this category. This patient developed a well defned showed a malignant neuronal component that resembled tumor in the same region, and the radiological impression neuroblastoma. The neuroblastic component ofen formed was that of an extra-axial tumor (Figure 3A).

Patient # 7 developed a malignant neoplasm in the cervical spinal cord resembling a neuroblastoma six months afer a grade i ganglioglioma was resected from the same region. Case # 8 had a biphasic tumor with a neuroblastic component and better diferentiated areas with papillary structures resembling the so-called papillary glioneuronal tumor (Figure 4A). The cells in the papillary component were positive for neuronal markers (Figure 4b). The glial component in this tumor was more typical of the glial component in gangliogliomas with pilocytic astrocytoma like areas. Patient # 9 had an unusual malignant neuronal tumor with focal pseudopapillary architecture (Figure 4C,D). The pseudopapillary pattern exhibited pleomorphic cells in vague clusters and nests in a discohesive alveolar pattern, and was strongly positive for synaptophysin, anti A B C D Figure 3: radiological and histological features of tumors in Category 2: A: Patient# 6: Contrast-enhanced axial t -weighted (tr/ tE=600/ 5) Mr image at presentation shows a heterogeneously enhancing right cerebellar mass (arrow).

Copies of radiological studies or pre-operative imaging The radiological studies were available in three of the reports were available for review in 7 cases. The radiological The cerebellar tumor in case # 6 was radiologically well impression was that of a well-circumscribed mass and circumscribed and partially cystic. The postoperative scans reported radiological evidence of calcifcations was noted within the no residual enhancing lesion. Eight of the 7 cases in category 3 included radiological radiological fndings as reports or copies of flms were information. Postoperatively, 28 patients received radiotherapy and chemotherapy, two received radiotherapy only, and three received chemotherapy only. Tere was no extracranial metastasis, and cerebrospinal dissemination was found in one patient 2 months afer partial excision and radiotherapy. A twelve patients in category received radiotherapy followed by chemotherapy, one patient received radiotherapy only. At the end of the follow up period, six patients were dead of disease and six were alive with disease. Tirteen patients A: Contrast-enhanced coronal t -weighted (tr/tE=600/ 5) received both radiotherapy and chemotherapy, three Mr image depicts a predominantly peripheral enhancement and a centrally necrotic mass (large arrow) that partially expands the received chemotherapy only. At the end of the follow-up period, fve image shows a heterogeneously enhancing mass predominantly patients were dead of disease, were alive with residual in the posterior right temporal lobe (large arrow). Moderate concurrent vasogenic edema is present (small arrows), as is or recurrent disease, and one had no radiological evidence partial efacement of the lef lateral ventricle (curved arrow). The patient is a typical example of the radiological appearance of Category 3 with cerebrospinal dissemination died 6 months afer tumors. This blumcke et al (38%; n= 7) (29), Luyken et al (50%; n=2) study was undertaken to defne the clinicopathological (26) and Majores et al (60%; n=5) (25). This diference may characteristics of malignant glioneuronal tumors and refect the more stringent criteria used in this study for the to identify morphological features that may aid in their selection of anaplastic ganglioglioma or may simply refect classifcation. We could distinguish three intuitive categories limited number of cases in each study. This is partly due to the limited with more aggressive gangliogliomas can be supported numbers for statistical validity of such analyses. The exact classifcation of these by providing stricter criteria for the identifcation of a neoplasms is not clear, and there is doubt whether they ganglion cell tumor that is geographically distinct from the can be considered within the embryonal tumor group or anaplastic component with bizarre ganglion cells as well should even be considered a single category (9, 3,3). All as other features of typical low grade gangliogliomas, also tumors in category 2 had low grade glial components or a verifed with the use of a panel of immunohistochemical concurrent grade i ganglioglioma which distinguish them markers. The radiological were expected to show identical features to high-grade features of category 2 tumor were similar to the tumors gliomas with increased mitotic activity, prominent vascular in the other two categories and distinct from typical endothelial proliferation and necrosis including palisading glioblastomas. High grade glial components showed distinctly exhibited anaplastic recurrence of the neuronal component higher Mib labeling index and occasionally positive P53 demonstrated variable radiological characteristics (32-35). This tumor The malignant glial component of Category tumors may demonstratedadistinctivepapillaryarchitecturereminiscent not be always astrocytic; it may also be oligodendroglial. The tumor in While our series did not include any tumor with an this category had a clear neuroblastic component that was oligodendroglioma-like malignant component, cases strongly positive with the neuronal antibodies and negative displaying anaplastic oligodendroglioma have been for glial markers. While the neuroblastic elements and the glial reported to range between 38% to 60% in various studies component of this case are diferent from the typical 64 Cilt/Vol. One can assume that some of identifed malignant variants of papillary glioneuronal the category 3 tumors may have been malignant infltrating tumors, broadening this entity and raising the question gliomas with an unusual degree of neuronal diferentiation. Tese features have been easily identifed histologically and Category 3 tumors in our study were malignant neoplasms immunohistochemically. They have noted course was similar to those in the above mentioned study a high rate of Cns dissemination in this group of tumors as (3). While there was only one tumor with cerebrospinal distinct from typical glioblastoma even though the overall dissemination in this group, it is possible that the Category survival was quite similar. One argument in 7 tumors were dead of tumor at the end of the follow favor of this suggestion is that the study by Perry et al. While this seems to be much longer compared has documented tumors with anaplastic oligodendroglial to the study of Perry et al. Terefore, it may not be entirely accurate to malignant features in one or both histological components. They were predominantly cerebral (32/36 cases) but it was crucial to reproducibly distinguish Category 3 tumors occasionally involved the cerebellum or the spinal cord. PnEts can also interpretation, the expression of neuronal markers was be considered to exhibit neuronal and glial diferentiation at consistently demonstrated in addition to a histologically least on immunohistochemical grounds (2,38). Terefore, the distinction of the these neoplasms are typically composed of monomorphous malignant glioneuronal tumors from typical infltrating and predominantly undiferentiated small cells and gliomas was based on a combination of light microscopic demonstrate a high rate of cerebrospinal dissemination.

Retirement-from-sport considerations following pediatric sports-related concussion: case illustrations and institutional approach. Patients with persistent symptoms 3 months post-injury should be referred for interdisciplinary treatment if available. There is controversy regarding the diagnosis of persistent post-concussion symptoms because there is signifcant symptom overlap with other diagnoses that can result as a consequence of a traumatic experience, for example, depression, anxiety, and post-traumatic stress disorder, as well as the sequelae of pain related to comorbid conditions such as post-traumatic Table 4. Chronic pain syndrome Thus, the priority for primary care providers remains managing Cervical strain/whiplash associated disorder symptoms and encouraging patients to gradually return to Substance abuse or polypharmacy activity guided by symptom tolerance to prevent delays in Somatic symptom disorder recovery. Patients who receive education and treatment Factitious disorder earlier are more likely to have fewer persisting symptoms Malingering later. It is also important to note that there is frequently an interplay of symptoms, social circumstances, and subsequent development of complications. The particular cluster of presenting symptoms will vary among patients, necessitating an individualized approach to management. Accordingly, one of the primary aims of the guideline is to assist in providing recommendations for management of these patients at risk using a symptom-based approach. Primary care providers should be aware of symptom interaction as some symptoms may exacerbate others. After a brief period of rest during the acute phase (24–48 hours) after injury, patients can be 4. While there are few treatments for the early stage of concussion recovery, it is notable that providing psychoeducational intervention and supportive reassurance about concussive symptoms, expectations of recovery and strategies for symptom reduction are highly effective for reducing persisting symptoms. Primary care providers must carefully monitor for patients who do not follow the anticipated pattern of recovery. For those who have had complete symptom resolution, no intervention apart from the provision of injury prevention strategies is required. However, for those with persistent symptoms or decline in function, emphasis needs to be placed on regular monitoring by healthcare professionals and identifcation of potentially treatable symptoms. Obtaining a history of medical problems, performing a careful physical examination, an extensive review of concussion symptoms, and considering the response to exertion testing is essential when developing the differential diagnosis of persistent post-concussion symptoms. In turn, efforts to update the patient’s family on the chosen intervention strategies should be considered, as their support is often a key component to maximizing patient independence and psychosocial adjustment. It is also important to approach the patient’s tolerance towards activity with vigilance, as going beyond his or her threshold may result in the worsening of symptoms. Persistent symptoms describe a constellation of nonspecifc symptoms that may be linked to other conditions such as depression, pain, headache, sleep disturbance, vertigo, irritability, anxiety, diffculty with concentration and chronic fatigue, which do not necessarily refect ongoing physiological brain injury.

Unfortunately, the management of persistent post-traumatic headache is often diffcult and there is a paucity of research in the area and no evidence-based treatment guidelines available to guide management. Post-traumatic headache is classifed as a secondary rather than primary headache subtype. Headache subtypes are then based upon clinical characteristics that best ft primary headache categories. Clinical studies to date have been conficting regarding the type of headache that most commonly occurs in post-traumatic headache. Some studies have suggested that the headaches most commonly resemble migraine headaches, whereas other studies have suggested that headaches more commonly resemble tension-type headache. Accordingly, it is important to provide clear instructions on the maximal allowable daily dosing and the maximum allowable monthly frequency of medication consumption combination analgesics, narcotic analgesics, ergotamines, triptans, and diclofenac potassium oral solution can be utilized no more than 10 days per month to avoid medication overuse (rebound) headache.

The case study is not intended be prescriptive or to imply that the approach taken here is the only way to manage an osteosarcoma patient, nor is it intended to be used as a diagnostic tree. Practitioners interested in oncology are encouraged to research current diagnostics, chemotherapeutics, and modalities appropriate for each cancer patient as the best way of keeping current in this rapidly evolving field of veterinary medicine. The case history includes the rationale for ‘‘decision points,’’ the interventions the clinician would make in appropriately treating the patient. A 9 yr old, male, neutered Labrador retriever mixed-breed named ‘‘Bo’’ presented with a 2 mo history of mild lameness in the right front limb. He had a grade 2/4 lameness in the right front limb and was mildly painful over the right carpus with no visible swelling. Distal limb radiographs revealed an osteolytic and proliferative lesion of the distal carpus (Figure 1). Three view thoracic radiographs revealed no visible lesions and were considered normal. Decision point rationale: Approximately 8% of dogs with osteosarcoma have visible metastasis on radiographs at diagnosis. Other diseases on the differential list are a metastatic bone tumor and infectious disease (bacterial, fungal). The tables are intended as a quick tumor) and systemic disease (micrometastasis) was discussed. Three-view thoracic radiographs were performed every 3 mo following completion of chemotherapy. Nine mo after the last chemotherapy treatment, radiographic evidence of metastasis was found. Because Bo currently had a good quality of life, the owners opted to begin therapy for the metastasis. Once metastatic disease becomes clinically apparent, a site reveals a cellular architecture indicative of sarcoma, including realistic goal of therapy is to attempt to stabilize it or slow its indistinct cytoplasmic borders and atypical nuclei.

This type of acceptance Good communication skills are a key component of a successful 39 will help the owner of a cancer patient to be open and express practice. Oncology cases raise the bar by placing a premium on the difficult or even embarrassing issues and questions. Statements like clinician’s ability to engage and empathize with the owner of a cancer ‘‘I can see that this is difficult to discuss’’ or ‘‘it is common for patient. Cancer is an upsetting diagnosis associated with emotionally these masses to be overlooked until they become large’’ can be charged situations. The goal of the initial discussion is to present reassuring to the client and open lines of discussion. Understanding costs, risks, benefits, and potential outcomes technique for obtaining an accurate patient history and having is crucial for owners of pets with cancer, as is feeling part of a caring fruitful discussions about diagnostic results and treatment choices. Multiple studies in human oncology Open-end questions tend to strengthen the client–veterinarian confirm that effective communication skills are a critical source of 40–42 relationship by allowing pet owners to tell their story. Nonverbal Communication Open-end questions often begin with the words ‘‘what’’ or A large part of communication between individuals is nonverbal and ‘‘how’’ and allow the client to talk using their own vocabulary. Unspoken information that cannot be hidden is open-end question is a good way to begin an interview, such as, still being exchanged at all times. Frankly addressing issues when nonverbal cues indicate a client ‘‘Are you thinking about euthanasia? Practitioners should be mindful of their own nonverbal thoughts about the options we have discussed? When a new diagnosis has been made, asking a client what they know about the disease rather than Empathy offering a description of the problem can save time and show the Empathy is the ability to imagine what a client is experiencing and to client that they, and their knowledge, are valued. Stated another way, empathy can be thought of as having a client know that he or she is being seen, heard, Reflective Listening and accepted. This technique is a good way as individuals with feelings and emotions, and not just as a customer. Reflective statements not only the ability to express empathy improves with practice. A common tell clients they are being heard but also allow them to correct concern is that acknowledging a client’s concerns or state of mind misconceptions. In that sense, reflective-listening comments will escalate that person’s emotions. Experts agree that the opposite operate as a kind of check step in how you perceive the case and usually occurs. The classic reflective listening response helps clients know that their feelings are seen and accepted. Examples of nonverbal displays of empathy include varying saying’’ or ‘‘it sounds like. Together, the healthcare team can Breaking the News make decisions and implement a treatment plan that proves Clients need time to adjust to the idea that their pet may have satisfactory for all concerned. Being empathetic and candid in discussing a suspected or confirmed cancer diagnosis End-of-Life Decisions often helps the pet owner accept the situation and make treatment One of the options that veterinary medicine has to offer in order to decisions in coherent, proactive manner. Many cancer cases will announce a cancer diagnosis with a ‘‘warning shot’’ phrase, such as, conclude with a discussion and an end-of-life decision involving the ‘‘I’m afraid the news is not good. Understandably, these for the client’s response is a good approach to discussing a cancer discussions can be difficult. An example would be, ‘‘I’m so sorry about this upsetting the pet owner realize that euthanasia is a humane alternative and a diagnosis. Unfortunately, viable option to end a pet’s suffering or an unacceptably poor quality it’s not curable but the good news is that it is treatable. Veterinarians should advise clients to consider euthanasia when pause and ask, ‘‘Would you like to discuss further testing and the clinician can no longer prevent suffering, preserve the pet’squality treatment now, or would you prefer to talk later? In cases where Most clients will have a negative response to the words euthanasia is advisable, the veterinarian should consider offering the ‘‘cancer’’ and ‘‘chemotherapy. Many practices now have a designated room that provides uncommon for an initial refusal to consider more testing or privacy and a non-clinical, stress-free atmosphere for the euthanasia treatment to change with further discussion about how well most procedure.

A Practice Team practitioner who takes that approach almost always helps the pet It is important to enlist the skills and resources of the entire owner transition from shock and sadness over a cancer diagnosis to healthcare team when caring for an oncology patient. By ‘‘speaking with one voice,’’ the practice owner, it is important to use lay terminology or medical vocabulary minimizes the potential for confusion and disillusionment by the accompanied by a clear explanation. Using clinical terminology client when an often sensitive oncology case is involved. An that clients are unfamiliar with will only create confusion or informed, empathetic team approach to presenting information embarrassment and add to the owner’s sense of being over empowers the client to make an educated decision on treatment whelmed. When presenting treatment options, it is important to options and helps create realistic expectations for treatment avoid overwhelming the owner with choices and unnecessary detail. First assessing the client’s goals and limitations is an integral part of presenting options. When suggesting that the patient’s prognosis is the Critical Role of Staff Training poor, keep in mind that only the pet owner can determine the value the entire healthcare team can contribute in a unified fashion to of the additional time treatment may provide. To advised that median survival time does not predict what the accomplish this, a thoughtful approach must be taken to defining outcome will be for an individual patient. Balancing realism with the roles and responsibilities of each staff member involved in an optimism is critical for veterinarians treating cancer. In particular, staff training is most effective Cancer treatment is case specific and multifactorial. Treatment when it addresses empathetic interaction with pet owners and safe modalities are based on the tumor type and its stage. An expectation that all staff critical factor in deciding which treatment modalities to use, or members will effectively contribute to oncology case management whether to treat the disease at all or to instead rely on palliative is not realistic unless they have been trained to do so. Chemotherapy, immunotherapy, adjunctive therapies, should assess their training programs to ensure that the unique radiotherapy, and surgery can be used individually or in tandem requirements of oncology treatment are specifically addressed. Chemotherapy is now commonly used in veterinary healthcare team to implement clinical protocols are provided in oncology.

While waiting allergy symptoms beer order cheap prednisolone line, it can be stressful for patients and their families and carers to cope with uncertainty allergy forecast waco buy prednisolone 40 mg fast delivery, but is important for doctors to make sure the information is as accurate as possible before explaining the diagnosis allergy shots for child 10 mg prednisolone amex. Information given during consultations It can be difficult for anyone to remember all the information received during a visit to a medical specialist allergy treatment pipeline best purchase for prednisolone. Even when a person is expecting to hear bad news allergy medicine veramyst buy prednisolone without a prescription, the diagnosis or information about the chances of survival may be a shock allergy medicine not strong enough discount prednisolone 40 mg otc. People in these circumstances often find that they ‘switch off’ and don’t remember a lot of what they have been told. Patients should let their doctors know how much information they would prefer at each session. Some people will want their doctor to tell them everything immediately, even if the news is bad (see Discussing the outlook (prognosis) later in this chapter). Others will prefer to hear an outline at first, then think about things before asking for more information. Some patients might want to ask about possible participation in any relevant clinical trials. Patients and their families or carers have the right to receive information they can understand. They should feel free to ask questions, to check the information when it is not clear, and to ask doctors to repeat anything they missed. Patients should ask their doctor to write down the most important information, and should feel free to ask about what other kinds of information are available. People with cultural issues they would like to discuss with a trained professional should ask their doctor to arrange this. People whose first language is not English should ask their doctor to arrange for a health interpreter to come to consultations. It is better to use a trained professional health interpreter than to rely on family members to interpret. Usually a family member or carer cannot be a good interpreter and support the patient properly at the same time. There is less stress and the information is clearer with a professional interpreter, who is trained in how to translate medical terminology and how to deal with people who have cancer.

More information A booklet about telling children about the diagnosis (Talking to kids about cancer. A guide for people with cancer, their families and friends), is available from However, many people in this situation say that being told the worst possible outcome allows them to think about the future, make plans, and make sure that their family members understand the situation. Not everyone feels like this and some will prefer not to be told the worst possible scenario. People with cancer should let their doctor know how they want to handle information about the prognosis. Often a person finds it easier to understand information about the outlook if their doctors explains it in several different ways – for example, tells them the average survival time for a person with the particular type of tumour and the longest survival times using words, statistics and graphs. If a patient, their family or carer finds it hard to understand the information, they should ask the doctor to explain it in a different way. At any time during treatment, they can tell someone in the treatment team if they would like information about the prognosis. Counselling Most people with brain tumours find it helpful to talk about the information they have been given. Sometimes it can be useful to talk with a specially trained counsellor such as a psychologist, social worker or psychiatrist. Often, patients prefer to talk to a trained professional about their anxieties and fears instead of talking to their family. The doctor or the person coordinating multidisciplinary care will be able to arrange counselling or explain about the services that are available.

Generally, doctors should encourage people with any medical condition to be involved in making treatment decisions. The doctor’s role is to give the patient honest information and advice and help them to come to a decision, but not force a decision on them. Making decisions can be difficult for someone while they are still adjusting to the stress of receiving a diagnosis of a serious illness. It may be hard to concentrate, to process all the information, and to work out the likely risks and benefits of each treatment option. Making decisions about treatment can also force the person to face difficult thoughts about their goals, personal values, social, occupational and family roles. For people with brain tumours, making decisions can be especially difficult because of problems with memory, processing information, planning and reasoning, which are caused by the tumour or treatments. All these problems can make it very hard to make a decision about treatment and communicate it to others. Despite these challenges, doctors should make sure that patients have the opportunity to participate in making decisions about their treatment as much as they are able. There are national ethical and legal guidelines that doctors must follow when giving the person information about the research and getting their consent to participate. Most people find it painful to think about the possibility that they may not be able to make independent decisions in the future. However, it is generally helpful for the person and their family to think about this early and make a contingency plan, just in case the person’s health worsens in future. Early after the diagnosis, a person with a brain tumour should consider asking someone to take responsibility for making decisions for them in future if they cannot make decisions for themselves. This can help the patient, their family and health professionals feel more confident about future decision-making. A social worker or another member of the patient’s care team can provide information about how to appoint a ‘surrogate decision maker’ in your state or territory.

Making their wishes known will enable the nominated decision maker to express the person’s wishes on their behalf. This type of planning can give the patient confidence that they will continue to be treated according to their wishes, even if they can no longer express these. It also reduces distress for family members and health professionals, because they can feel confident that they are continuing to respect the patient’s wishes. Coping with difficult medical procedures and treatment A person with a brain tumour will usually undergo several medical procedures during the processes of diagnosis, treatment and follow-up. Even tests that do not normally cause pain or physical discomfort, such as blood tests and X rays, can be highly stressful for the person if they are anxious about the meaning of the test results. Other procedures, such as surgery, radiotherapy and chemotherapy can be uncomfortable or painful, have significant side effects, or may not be available nearby, so the person needs to spend time away from home and away from their normal sources of emotional support. When undergoing any test or procedure, the patient and their family or carers should make sure they fully understand what it is for, what it involves and what to expect during and after (Table 2. There is good evidence that people who have this information generally find tests and procedures less stressful, and may experience fewer and less severe side effects.

Most advances in the treatment of brain tumours have happened because new approaches were tested in clinical trials. When agreeing to participate in the clinical trial, each patient does not know whether they will be given the new treatment or the standard treatment. The committee carefully assesses the design and any possible problems for patients before deciding whether the trial is safe, ethical and appropriate for patients. Why clinical trials are important Just because a treatment is new does not mean it is better. Clinical trials are the main way of finding out if a new treatment is better than the current best treatment of cancers, including the treatment of brain tumours. Clinical trials are important because only proper, rigorous scientific testing can enable researchers to discover whether or not a new treatment (such as a medicine, surgical technique or type of radiotherapy) is better than the best available standard treatment. If a treatment has not been tested properly in clinical trials, it remains unproven and can be controversial. Clinical trials give patients the opportunity to receive new treatments and to make a contribution to the improvement in the care of future patients. Recent advances in brain tumour treatments have been made after researchers analysed the results of large, well designed and well conducted clinical trials. These trials have led to new treatments for brain tumours, which are now approved by the Australian Therapeutic Goods Administration and paid for by the Pharmaceutical Benefits Scheme. The purpose of different types of clinical trials Clinical trials in patients are usually performed after years of scientific testing in the laboratory and in animals. Any treatment that seems to be effective must then be tested in Adult gliomas (astrocytomas and oligodendrogliomas): a guide for patients, their families and carers 20 2018 Adult gliomas (astrocytomas and oligodendrogliomas): a guide for patients, their families and carers patients to find how it should be given, how safe it is, what the side effects are and whether it is effective in people with the condition. Clinical trials are conducted over time at different stages to collect different types of information about the new cancer treatment. They aim to find out how the treatment should be given, how often it should be given, and what dose is safe. These trials are randomised, which means patients are randomly selected to either get the new treatment or get the standard current treatment. This way of designing a trial ensures that patients in each group are similar overall. This method makes the results more reliable, because it helps prevent patients’ and doctors’ expectations affecting their experience of receiving the treatment or observing its effects. However, sometimes a trial may not be blinded when it is not possible to disguise treatments. Sometimes there is no accepted standard treatment that the new treatment can be compared with. In this situation a groups of patients taking the new treatment is usually compared with a similar group receiving usual care, or with a group receiving placebo. They are usually required by health system authorities before a new treatment can become a standard part of care. Adult gliomas (astrocytomas and oligodendrogliomas): a guide for patients, their families and carers 21 Adult gliomas (astrocytomas and oligodendrogliomas): a guide for patients, their families and carers 2119 Clinical trials in Australia Who conducts clinical trials? In Australia, clinical trials in patients with brain tumours may be conducted by. Many clinical trials of new treatments for brain tumours are sponsored by pharmaceutical companies. These trials usually have a sound scientific basis and are well designed and conducted. All doctors involved in designing and running the trial (investigators) must declare their relationship to pharmaceutical company and any fees they have received. Cooperative groups are groups of doctors and researchers who share a scientific interest in a specific disease. They may also receive funding or medicines with which to run clinical trials from pharmaceutical companies. Most clinical trials run by cooperative groups are initiated and designed by specialist doctors. Sometimes a clinical trial is conducted at a few hospital units or a small group of hospitals. Before patients can be enrolled onto a clinical trial in Australia, the trial must be reviewed by other expert clinicians and researchers to ensure that it is scientifically well designed and will be able to answer the study question. It must also be reviewed by at least one registered Human Research Ethics Committee to ensure that the trial protocol adheres to national guidelines as set out in the National Health and Medical Research Council’s statement on ethical conduct in human research. In Victoria, about one in twenty (5%) patients with gliomas participate in a clinical trial during their illness, according to recent data from the Victorian Cancer Registry. Ideally, all patients should have access to treatment in a centre where clinical trials are offered. However, geographical distances are a barrier to participation for patients in rural and remote communities. For extremely rare cancers, like anaplastic astrocytomas and oligodendrogliomas, it is unlikely that there would be enough patients in Australia alone to v National Health and Medical Research Council, Australian Research Council, Australian Vice-Chancellors’ Committee. Participating in a clinical trial Understanding what the trial will involve and agreeing to participate Doctors running a clinical trial are responsible to make sure that every person who participates. This can be difficult when a person has cognitive impairment (problems with memory, thinking, reasoning, understanding information, making decisions or judging their actions). However, the National Health and Medical Research Council’s statement on ethical conduct in human researchvi states that people with cognitive impairment are entitled to participate in a clinical trial. That document provides guidance for their participation, and states that in some situationsvii consent can be given by another person who has been given legal authority to make decisions for the patient. Patients and their families or carers should discuss these issues with the doctor. Occasionally, a patient who is able to think clearly and wishes to participate in a clinical trial may be unable to sign the required forms due to a physical disability caused by the tumour, such as weakness of their writing hand. In this situation, alternatives depend on legislation that applies in that state or territory, for example. Spoken consent to participate may be legally valid if it is witnessed by an independent third party.
