Challenges and limitations of clinical trials in the adolescent and young adult CNS cancer population: A systematic review.

Background: The adolescent and young adult (AYA) cancer population, aged 15-39, carries significant morbidity and mortality. Despite growing recognition of unique challenges with this age group, there has been little documentation of unmet needs in their care, trial participation, and quality of life, particularly in those with primary brain tumors. Methods: A systematic literature review of 4 databases was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. Studies included editorials, reviews, and practice guidelines on the challenges and limitations faced by the AYA population. Papers had to address CNS tumors. Results: Sixty-eight studies met the inclusion criteria. The challenges and limitations in clinical trials in the AYA population were synthesized into 11 categories: molecular heterogeneity, tumor biology, diagnostic delay, access to care, physician factors, patient factors, primary brain tumor (PBT) factors, accrual, limited trials, long term follow up, and trial design. The published papers' recommendations were categorized based on the target of the recommendation: providers, coordination of care, organizations, accrual, and trial design. The AYA cancer population was found to suffer from unique challenges and barriers to care and the construction of trials. Conclusions: The AYA CNS cancer population suffers from unique challenges and barriers to care and construction of trials that make it critical to acknowledge AYAs as a distinct patient population. In addition, AYAs with primary brain tumors are underrecognized and underreported in current literature. More studies in the AYA primary brain tumor patient population are needed to improve their care and participation in trials.

Body image and cancer-related lymphoedema: A systematic review.

OBJECTIVE: Cancer-related lymphoedema is a common side effect of cancer, affecting 24%-49% of people with cancer. Body image contributes to the well-being of individuals with this condition. This systematic review aimed to explore, for the first time, the state of the science concerning body image in cancer-related lymphoedema, including how body image is measured and variables associated with body image concerns. METHODS: Six databases were systematically searched for peer-reviewed articles describing empirical quantitative studies where body image was measured with a reliable and valid measurement tool in adults with cancer-related lymphoedema. RESULTS: Nine studies with 977 participants were included. The studies involved individuals who had experienced breast, head and neck, melanoma, and urogenital cancers and developed lymphoedema. There was considerable heterogeneity in body image measures used, precluding meta-analysis. The following variables were associated with increased body image concern: higher body integrity beliefs, experience of physical changes (e.g. pain) and differences in sensation and function, including changes in appearance related thoughts, feelings and emotions. Several studies described behavioural and psychological interventions which positively impacted body image outcomes in individuals with lymphoedema relating to specific cancers. CONCLUSION: Regular screening for body image concerns could encourage more positive body image awareness in individuals with cancer-related lymphoedema and lessen some of its associated negative consequences. Future longitudinal and individual differences research in this area is important to inform intervention development. There is also need for a more standardised approach to the study and measurement of body image in people with cancer-related lymphoedema.

A qualitative meta-synthesis examining spirituality as experienced by individuals living with terminal cancer.

This review aimed to examine and synthesise literature on spirituality as experienced by individuals living with terminal cancer. Six databases were systematically searched for studies with qualitative findings relevant to spirituality and terminal cancer. Thirty-seven studies were included and thematic synthesis was used to identify themes. Analytical themes included: making sense of dying; living with dying; feeling connected; and being reflective. This review highlights how the experience of spirituality can positively impact the lives of terminal cancer patients. Further, these findings suggest that spirituality can be a transformative experience that allows individuals to experience peace at end of life.

Rare presentation of enoxaparin-induced skin necrosis in a postoperative patient.

Enoxaparin-induced skin necrosis is a rare complication of low-molecular weight heparin (LMWH) therapy. We describe a woman in her 50s who developed deep vein thrombosis (DVT), thrombocytopenia and necrotic skin lesions after initiation of enoxaparin for DVT prophylaxis. Despite high clinical suspicion of heparin-induced thrombocytopenia syndrome and a positive heparin-platelet factor 4 antibody, heparin serotonin assay was negative. This case emphasises the importance for clinical vigilance regarding complications to LMWH therapy.

Trends in radiation dose for low grade gliomas across the United States.

PURPOSE: Adjuvant radiation is often used in patients with low grade gliomas with high-risk characteristics with a recommended dose of 45-54 Gy. We used the National Cancer Database (NCDB) to see which doses were being used, and if any difference was seen in outcome. METHODS: We queried the NCDB for patients with WHO Grade 2 primary brain tumors treated with surgery and adjuvant radiotherapy. We divided the cohort into dose groups: 45-50 Gy, 50.4-54 Gy, and > 54 Gy. Multivariable logistic regression was used to identify predictors of low and high dose radiation. Propensity matching was used to account for indication bias. RESULTS: We identified 1437 patients meeting inclusion criteria. Median age was 45 years and 62% of patients were > 40 years old. Nearly half of patients (48%) had astrocytoma subtype and 70% had subtotal resection. The majority of patients (69%) were treated to doses between 50.4 and 54 Gy. Predictors of high dose radiation (> 54 Gy) were increased income, astrocytoma subtype, chemotherapy receipt, and treatment in later year (2014). The main predictors of survival were age > 40, astrocytoma subtype, and insurance type. Patients treated to a dose of > 54 Gy had a median survival of 73.5 months and was not reached in those treated to a lower dose (p = 0.0041). CONCLUSIONS: This analysis shows that 50.4-54 Gy is the most widely used radiation regimen for the adjuvant treatment of low-grade gliomas. There appeared to be no benefit to higher doses, although unreported factors may impact interpretation of the results.

Virtual online consultations: advantages and limitations (VOCAL) study.

INTRODUCTION: Remote video consultations between clinician and patient are technically possible and increasingly acceptable. They are being introduced in some settings alongside (and occasionally replacing) face-to-face or telephone consultations. METHODS: To explore the advantages and limitations of video consultations, we will conduct in-depth qualitative studies of real consultations (microlevel) embedded in an organisational case study (mesolevel), taking account of national context (macrolevel). The study is based in 2 contrasting clinical settings (diabetes and cancer) in a National Health Service (NHS) acute trust in London, UK. Main data sources are: microlevel--audio, video and screen capture to produce rich multimodal data on 45 remote consultations; mesolevel--interviews, ethnographic observations and analysis of documents within the trust; macrolevel--key informant interviews of national-level stakeholders and document analysis. Data will be analysed and synthesised using a sociotechnical framework developed from structuration theory. ETHICS APPROVAL: City Road and Hampstead NHS Research Ethics Committee, 9 December 2014, reference 14/LO/1883. PLANNED OUTPUTS: We plan outputs for 5 main audiences: (1) academics: research publications and conference presentations; (2) service providers: standard operating procedures, provisional operational guidance and key safety issues; (3) professional bodies and defence societies: summary of relevant findings to inform guidance to members; (4) policymakers: summary of key findings; (5) patients and carers: 'what to expect in your virtual consultation'. DISCUSSION: The research literature on video consultations is sparse. Such consultations offer potential advantages to patients (who are spared the cost and inconvenience of travel) and the healthcare system (eg, they may be more cost-effective), but fears have been expressed that they may be clinically risky and/or less acceptable to patients or staff, and they bring significant technical, logistical and regulatory challenges. We anticipate that this study will contribute to a balanced assessment of when, how and in what circumstances this model might be introduced.
