In elderly patients with glioblastoma, the addition of temozolomide to short-course radiotherapy resulted in longer survival than short-course radiotherapy alone. (Funded by the Canadian Cancer Society Research Institute and others; ClinicalTrials.gov number, NCT00482677 .).

BackgroundHead and neck cancer squamous cell carcinoma (HNSSC) patients report substantial rates of clinically significant depression and/or anxiety, with dysphagia being a predictor of distress and poorer quality of life. Evidence-based dysphagia interventions largely focus on the remediation of physical impairment. This feasibility study evaluates an intervention which simultaneously uses a psychological therapy approach combined with swallowing impairment rehabilitation.MethodsThis prospective single cohort mixed-methods study, recruited HNSCC patients with dysphagia, from two institutions. The intervention combined Cognitive Behavioural Therapy with swallowing therapy (CB-EST), was individually tailored, for up to 10 sessions and delivered by a speech and language therapist. Primary acceptability and feasibility measures included recruitment and retention rates, data completion, intervention fidelity and the responsiveness of candidate outcome measures. Measures included a swallowing questionnaire (MDADI), EORTC-QLQH&N35, dietary restrictions scale, fatigue and function scales and the Hospital Anxiety and Depression Scale (HADS), administered pre-, post-CB-EST with three month follow-up and analysed using repeated measures ANOVA. Qualitative interviews were conducted to evaluate intervention processes.ResultsA total of 30/43 (70%) eligible patients agreed to participate and 25 completed the intervention. 84% were male, mean age 59 yrs. Patients were between 1 and 60 months (median 4) post-cancer treatment. All patients had advanced stage disease, treated with surgery and radiotherapy (38%) or primary chemoradiotherapy (62%). Pre to post CB-EST data showed improvements in MDADI scores (p = 0.002), EORTC-QLQH&N35 (p = 0.006), dietary scale (p < 0.0001), fatigue (p = 0.002) but no change in function scales or HADS. Barriers to recruitment were the ability to attend regular appointments and patient suitability or openness to a psychological-based intervention.ConclusionsCB-EST is a complex and novel intervention, addressing the emotional, behavioural and cognitive components of dysphagia alongside physical impairment. Preliminary results are promising. Further research is required to evaluate efficacy and effectiveness.

A guideline to assist in the de-escalation of inappropriate medications in palliative cancer patients was developed from current literature. The OncPal Deprescribing Guideline was successfully validated, demonstrating statistically significant concordance with an expert panel. We found that the incidence of PIMs was high in our patient group, demonstrating the potential benefits for the OncPal Deprescribing Guideline in clinical practice.

Accurate inguinal and pelvic nodal staging in anal cancer is important for the prognosis and planning of radiation fields. There is evidence for the role of 18-fluorodeoxyglucose positron emission tomography (FDG-PET) in the staging and management of cancer, with early reports of an increasing role in outcome prognostication in a number of tumours. We aimed to determine the effect of FDG-PET on the nodal staging, radiotherapy planning and prognostication of patients with primary anal cancer. Sixty-one consecutive patients with anal cancer who were referred to a tertiary centre between August 1997 and November 2005 were staged with conventional imaging (CIm) (including computed tomography (CT), magnetic resonance imaging, endoscopic ultrasound and chest X-ray) and by FDG-PET. The stage determined by CIm and the proposed management plan were prospectively recorded and changes in stage and management as a result of FDG-PET assessed. Patients were treated with a uniform radiotherapy technique and dose. The accuracy of changes and prognostication of FDG-PET were validated by subsequent clinical follow-up. Kaplan -Meier survival analysis was used to estimate survival for the whole cohort and by FDG-PET and CIm stage. The tumour-stage group was changed in 23% (14 out of 61) as a result of FDG-PET (15% up-staged, 8% down-staged). Fourteen percent of T1 patients (3 out of 22), 42% of T2 patients (10 out of 24) and 40% of T3 -4 patients (6 out of 15) assessed using CIm, had a change in their nodal or metastatic stage following FDG-PET. Sensitivity for nodal regional disease by FDG-PET and CIm was 89% and 62%, respectively. The staging FDG-PET scan altered management intent in 3% (2 out of 61) and radiotherapy fields in 13% (8 out of 61). The estimated 5-year overall survival (OS) and progression-free survival (PFS) for the cohort were 77.3% (95% confidence interval (CI): 55.3 -90.4%) and 72.2% (95% CI: 51.5 -86.4%), respectively. The estimated 5-year PFS for FDG-PET and CIm staged N2-3 disease was 70% (95% CI: 42.8 -87.9%) and 55.3% (95% CI: 23.3 -83.4%), respectively. FDG-PET shows increased sensitivity over CIm for staging nodal disease in anal cancer and changes treatment intent or radiotherapy prescription in a significant proportion of patients.

Objectives Cancer patients who have transitioned from curative intent chemotherapy or radiotherapy to palliative therapy have limited life expectancies. Due to this, medications for primary and secondary prevention or those with no short-term benefit are potentially inappropriate medicines in this patient group. These medications often have potentially harmful profiles, increasing the patient's adverse drug events, pill burden, and medication costs. This review evaluates the most current evidence to assess the outcomes and potential methods used for identifying and ceasing potentially inappropriate medications (PIMs) in palliative cancer patients. Methods A systematic review of the literature was conducted using the databases Ovid MEDLINE, PubMed, EMBASE, IPA, and CINAHL. Results Of the 51 articles examined in detail, three studies relating to cancer have been evaluated. In these retrospective and cross-sectional studies, the incidence of PIMs was shown in approximately 20 % of patients, although the studies were inconsistent. In addition, six studies were identified that demonstrated the evidence in other population groups; these studies have been selected to establish the evidence in large-scale retrospective studies, prospective cross-sectional studies, both demonstrating the prevalence of PIMs, as well as the outcomes of ceasing PIMs. Conclusion There is evidence that PIMs are commonly prescribed in palliative care patients. There are no studies that have identified the impact of ceasing PIMS in this setting. Published tools and implemented strategies have focused on the elderly populations. Further research is warranted in establishing clear guidelines for the identification of PIMs in palliative cancer patients as well as interventional studies assessing the outcomes of ceasing PIMs in these patients.

BACKGROUND AND PURPOSE:There is significant interest in whether diffusion-weighted MR imaging indices, such as the minimum apparent diffusion coefficient, may be useful clinically for preoperative tumor grading and treatment planning. To help establish the pathologic correlate of minimum ADC, we undertook a study investigating the relationship between minimum ADC and maximum FDOPA PET uptake in patients with newly diagnosed glioblastoma multiforme.
