Abstract
PURPOSE Patients with multiple brain metastases may be treated with whole-brain radiation therapy (WBRT). For these patients, symptom palliation and improvement of quality of life (QOL) and performance status is of the upmost importance. The objective of the present study was to determine the symptom experience and overall QOL in patients with brain metastases before and after WBRT. METHODS A total of 14 symptom scores and overall QOL were collected prospectively in 217 patients for up to 3 months. Wilcoxon signed rank test was applied to determine significant symptoms and QOL changes. Spearman's correlations were applied to determine the relationship between symptom scores and QOL. RESULTS Appetite loss, weakness, and nausea significantly increased from baseline, while balance, headache, and anxiety significantly decreased from baseline. At baseline, all symptoms other than coordination were significantly correlated with QOL. At 1-month follow-up (FU), changes in concentration, weakness, coordination, and balance were significantly associated with QOL changes. At 2-month FU, changes in pain, insomnia, concentration, balance, and depression were significantly associated with QOL changes. At 3-month FU, only change in nausea was significantly associated with QOL changes. CONCLUSIONS Following WBRT, certain symptoms may influence overall QOL to a greater extent than others, which may fluctuate with time.

Abstract
BACKGROUND Studies utilizing body mass index (BMI) have failed to show a consistent relationship between obesity and survival following treatment for colorectal cancer (CRC). Computerized tomography (CT) offers a reliable alternative approach to quantify body adiposity. We hypothesized that visceral obesity may negatively impact survival in CRC patients. AIMS AND METHODS A retrospective review of CRC patients who received adjuvant chemotherapy at a single center during the period 2006-2009 identified from a prospectively maintained database. Visceral adiposity was determined by measuring visceral fat area (VFA) on preoperative staging CT. All patients were followed up to study completion or death. RESULTS Sixty-two CRC patients with a mean age of 63.2 years received adjuvant chemotherapy and had imaging available for analysis. Thirty-five patients (56.5 %) had node positive disease. Thirty-one patients (50 %) were classified viscerally obese based on staging CT. 85.4 % of the patients completed adjuvant chemotherapy and visceral obesity was not associated with increased toxicity or failure to complete treatment. After a median follow-up of 65.2 months, patients with visceral obesity had a significantly lower overall survival (OS) (54.8 % vs 87.1 %, p = 0.004) and disease-free survival (DFS) (48.4 vs 77.4 %, p = 0.007) compared with patients without visceral obesity. There was no relationship between BMI and survival. Multivariate analysis using Cox proportional hazards model showed that visceral obesity was independently associated with reduced OS (Hazard ratio = 7.0; 95 % CI 2.0-24.6; p = 0.002). CONCLUSION This study shows that visceral obesity increases the likelihood of a poor prognosis in CRC patients receiving adjuvant chemotherapy thus underlying the value of lifestyle interventions to minimize visceral obesity in this patient cohort.

Abstract
The C-type lectin-like receptor CD161 is expressed by lymphocytes found in human gut and liver, as well as blood, especially natural killer (NK) cells, T helper 17 (Th17) cells, and a population of unconventional T cells known as mucosal-associated invariant T (MAIT) cells. The association of high CD161 expression with innate T-cell populations including MAIT cells is established. Here we show that CD161 is also expressed, at intermediate levels, on a prominent subset of polyclonal CD8+ T cells, including antiviral populations that display a memory phenotype. These memory CD161(int)CD8+ T cells are enriched within the colon and express both CD103 and CD69, markers associated with tissue residence. Furthermore, this population was characterized by enhanced polyfunctionality, increased levels of cytotoxic mediators, and high expression of the transcription factors T-bet and eomesodermin (EOMES). Such populations were induced by novel vaccine strategies based on adenoviral vectors, currently in trial against hepatitis C virus. Thus, intermediate CD161 expression marks potent polyclonal, polyfunctional tissue-homing CD8+ T-cell populations in humans. As induction of such responses represents a major aim of T-cell prophylactic and therapeutic vaccines in viral disease and cancer, analysis of these populations could be of value in the future.

Abstract
In 1996, the Toronto Sunnybrook Regional Cancer Centre developed the Rapid Response Radiotherapy Program (RRRP). The objective of this clinic is to consult, simulate, plan, and treat patients with palliative radiotherapy on the same day. In 2004, the RRRP initiated a program to provide clinical and research experience to undergraduate students interested in health sciences. The purpose of this study is to review the 10-year (2004-2013) experience of the RRRP and to examine whether the goals of the student program have been met. Students who worked in the RRRP from 2004 to 2013 were contacted to complete a short survey regarding their overall experience with the program and their current endeavors. Student accomplishments were collected from an internal database as well as PubMed. Descriptive statistics were used to analyze results. A total of 54 students from ten postsecondary institutions have worked in the RRRP; 29 were from the University of Waterloo undergraduate co-op program. In total, 214 articles with first authorship from students were published, 93 (43%) of which can be found on PubMed. Other accomplishments include 40 book chapters, 58 invited presentations, and 99 awards cumulatively. Qualitative data regarding student perspectives of their experience in the RRRP were also analyzed. Over the past 10 years, the RRRP has achieved its goal of providing quality medical and research experience to students interested in the health sciences. Using the responses of past and present students, we hope to continue to shape our program and provide unique opportunities to future students.

Abstract
OBJECTIVE To test the reliability, clinical and psychometric validity of the Brain Symptom and Impact Questionnaire (BASIQ) in patients with brain metastases. METHODS Brain metastases patients were interviewed using the BASIQ, Functional Assessment of Cancer-Brain (FACT-Br) and FACT-General (FACT-G) at baseline, with a follow-up assessment at 1 month. RESULTS Forty patients had complete one data and the median age was 64 years. Patients with higher KPS, ECOG of 2, primary breast cancer, or >3 brain metastases, scored higher on the symptom scale of the BASIQ. All subscales showed no significant change in patient symptoms from baseline to follow-up. CONCLUSION This study supports that the reliability, clinical and psychometric validity of BASIQ to be used in brain metastases patients.

Abstract
AIM To report the survival outcomes of patients with multiple brain metastases treated with whole-brain radiotherapy. PATIENTS & METHODS From 2004 to 2012, patients with brain metastases treated with whole-brain radiotherapy were included. Overall survival (OS) was calculated from the start of radiation treatment. Univariate and multivariate proportional hazard model of OS was conducted. Generalized R(2) statistic (ranged from 0 to 1) was calculated to determine the association with the outcome. RESULTS Nine-hundred-ninety-one patients were included. The actuarial median OS time was 2.7 months (95% CI: 2.5-2.9). Patients of older age (>65 years), lower Karnofsky performance status, not postoperative and patients with gastrointestinal, genitourinary or lung as opposed to breast cancer were more likely to have a shorter survival. CONCLUSION Short median survival of 2.7 months may reflect poorer prognosis of patients referred due to large amount of referrals for radiosurgery. Prognostic factors for survival should be considered at consultation.

Abstract
OBJECTIVE To validate the Brain Symptom and Impact Questionnaire (BASIQ) version 1.0 for brain metastases. METHODS Patients with brain metastases and their healthcare professionals (HCPs) assessed the relevance of the BASIQ on a 0-10 scale with 10 as extremely relevant. RESULTS A total of 52 patients and 20 HCPs participated in this study. In total, 95% of HCPs and 85% of patients found all items relevant. Balance and walking ability were rated relevant by 100% of patients and HCPs. Headache, nausea, energy, memory and ability to do housework were also rated relevant by 100% of HCPs. Over 95% of patients determined the items of ability to do housework, tiredness, energy, vision, memory and putting ideas into words as relevant. There were no items rated below 7 by patients or below 5 by HCPs. CONCLUSION This study indicates that BASIQ version 1.0 has valid content items encompassing disease-related symptom and impact on daily living.

Abstract
BACKGROUND AND OBJECTIVES Pediatric encephalitis has a wide range of etiologies, clinical presentations, and outcomes. This study seeks to classify and characterize infectious, immune-mediated/autoantibody-associated and unknown forms of encephalitis, including relative frequencies, clinical and radiologic phenotypes, and long-term outcome. METHODS By using consensus definitions and a retrospective single-center cohort of 164 Australian children, we performed clinical and radiologic phenotyping blinded to etiology and outcomes, and we tested archived acute sera for autoantibodies to N-methyl-D-aspartate receptor, voltage-gated potassium channel complex, and other neuronal antigens. Through telephone interviews, we defined outcomes by using the Liverpool Outcome Score (for encephalitis). RESULTS An infectious encephalitis occurred in 30%, infection-associated encephalopathy in 8%, immune-mediated/autoantibody-associated encephalitis in 34%, and unknown encephalitis in 28%. In descending order of frequency, the larger subgroups were acute disseminated encephalomyelitis (21%), enterovirus (12%), Mycoplasma pneumoniae (7%), N-methyl-D-aspartate receptor antibody (6%), herpes simplex virus (5%), and voltage-gated potassium channel complex antibody (4%). Movement disorders, psychiatric symptoms, agitation, speech dysfunction, cerebrospinal fluid oligoclonal bands, MRI limbic encephalitis, and clinical relapse were more common in patients with autoantibodies. An abnormal outcome occurred in 49% of patients after a median follow-up of 5.8 years. Herpes simplex virus and unknown forms had the worst outcomes. According to our multivariate analysis, an abnormal outcome was more common in patients with status epilepticus, magnetic resonance diffusion restriction, and ICU admission. CONCLUSIONS We have defined clinical and radiologic phenotypes of infectious and immune-mediated/autoantibody-associated encephalitis. In this resource-rich cohort, immune-mediated/autoantibody-associated etiologies are common, and the recognition and treatment of these entities should be a clinical priority.

Abstract
PURPOSE We evaluated the novel combination of aprepitant and granisetron for the prophylaxis of radiotherapy-induced nausea and vomiting (rinv) among patients receiving moderately-emetogenic radiotherapy for thoracolumbar bone metastases. METHODS In this single-centre two-arm nonrandomized prospective pilot study, patients undergoing single-fraction radiotherapy (8 Gy) received aprepitant 125 mg and granisetron 2 mg on the day of radiotherapy and aprepitant 80 mg on each of the first 2 days after the day of radiotherapy. Patients undergoing multiple-fraction radiotherapy (20 Gy in 5 fractions) received aprepitant 125 mg on day 1 of radiotherapy, aprepitant 80 mg on days 3 and 5 of radiotherapy, and granisetron 2 mg on every day of radiotherapy. Symptoms and total medication intake were recorded daily during the acute phase (day 1 of radiotherapy until the first day after the last day of radiotherapy), and the delayed phase (days 2-10 after the last day of radiotherapy). Control of vomiting, retching, and nausea was defined as no symptoms and no use of rescue medication. RESULTS Control rates for single-fraction patients (n = 13) were 100% for acute nausea, 62% for delayed nausea, 100% for acute vomiting and retching, and 85% for delayed vomiting and retching. Control rates for multiple-fraction patients (n = 6) were 67% for acute nausea, 83% for delayed nausea, 67% for acute vomiting and retching, and 83% for delayed vomiting and retching. No grade 3 or 4 toxicities attributable to the study intervention were observed. CONCLUSIONS The combination of aprepitant and granisetron was safe and efficacious for the prophylaxis of rinv after both single- and multiple-fraction moderately emetogenic radiotherapy for thoracolumbar bone metastases. Our results require confirmation in a larger population.
