The effect of NRAS mutations on the pathological features and clinical outcomes in patients with cutaneous melanoma was compared with that of tumors containing BRAF(V600E) mutations and tumors wild type for both (WT). Clinical outcome data were obtained from a prospective cohort of 249 patients. Mutations involving NRAS and BRAF(V600E) were detected by PCR and were sequence verified. Cox proportional hazards regression was performed to relate NRAS and BRAF mutations to clinical outcome. Seventy-five percentage of NRAS mutations occurred in tumors >1 mm thick (BRAF(V600E) 40%, WT 34%); 75% of NRAS mutations had >1 mitosis/mm(2) (BRAF(V600E) 40%, WT 55%). When compared to WT, multivariate analysis of melanoma-specific survival (MSS) identified NRAS mutations as an adverse prognostic factor [hazard ratio (HR) 2.96; P = 0.04] but not BRAF(V600E) mutations (HR 1.73; P = 0.23). NRAS mutations were associated with thicker tumors and higher rates of mitosis when compared to BRAF(V600E) and WT melanoma and independently of this, with shorter MSS.

Purpose: Multidisciplinary cancer care is a standard feature of high quality care. In many centers, the multidisciplinary meeting (MDM) is an integral component. A qualitative study was performed to explore health professionals' attitudes towards this model of care, the decision making processes, and dynamics among team members.Methods: A series of focus groups was conducted with health professionals who attend MDMs at our institution. Focus groups followed a semistructured format with open-ended questions. A thematic analysis was performed.Results: Four focus groups were held, attended by 23 participants including allied health professionals, specialist nurses, medical oncologists, and surgeons. All participants believed the primary objective of the MDM was to develop an individualized treatment plan. Several other key themes emerged. The MDM provided opportunities to improve communication, efficiency, and education as well as enhance professional relationships. Medical information was prioritized ahead of psychosocial details, with allied health professionals describing difficulty contributing to MDM discussion. Patient attendance at MDMs was opposed by health professionals because of concerns about the patient's ability to cope with the information discussed and the effect their presence would have on the dynamics of the decision-making process. Conclusion: Health professionals endorse MDMs as a usefultool in treating patients with cancer. Within this forum, both opportunities and constrains exist, with many benefits extending beyond the meeting itself into other clinical areas. Further study is warranted to establish an evidence base to ensure that both the possibilities and the limitations of this model of care are fully understood.

Disparities in the views of patients and facilitators about the preferred location, type of facilitator, and content of a support program may in part explain the poor uptake of existing support programs by patients with lung cancer and should be considered in the design of future programs.

The presence of a BRAF mutation does not necessarily 'drive' more rapid tumour growth but is associated with poorer MSS in patients with early-stage disease.

Despite an emerging evidence base for the potential benefits of GA and collaboration with geriatricians, medical oncologists reported a lack of access but a desire to engage with these services.

Elderly patients may be heterogeneous in their abilities to tolerate immunochemotherapy-associated toxicities. We describe the morbidity of rituximab-chemotherapy combinations among 205 newly-diagnosed diffuse large B-cell lymphoma (DLBCL) patients aged ≥60 years from 3 tertiary hospitals between 2009 and 2016, and explore the utility of retrospectivelyassigned baseline Comprehensive Geriatric Assessment (CGA) in predicting these toxicities. Seventy-three percent (146/201) experienced grade ≥3 toxicities, 81% (163/201) needed admission, 52% (107/205) had ≥2 unplanned admissions, 82/201 (41%) required dose reductions (DR) subsequent to Cycle 1, 39/166 (23%) had chemotherapy delays and 26/198 (13%) ceased therapy early. CGA was associated with pre-emptive baseline DR and perhaps because of this, did not predict grade ≥3 toxicities, ≥2 unplanned admissions or subsequent DR. Three-year overall survival (OS) of CGA-fit, CGA-unfit and CGA-frail patients was 82%, 60% and 53%, respectively. Three-year progression-free survival (PFS) of CGA-fit, CGA-unfit and CGA-frail patients was 66%, 58% and 46%, respectively. OS of CGA-fit patients was not statistically different from CGA-unfit patients, but was superior to CGA-frail patients (hazard ratio 2Á892, 95% confidence interval 1Á275-6Á559, P = 0Á011). PFS differences were not statistically significant. Baseline DR and early therapy cessation were associated with inferior OS and PFS independent of CGA. Prospective studies are needed to confirm if CGA-adapted treatment strategies minimize morbidity and improves survival.
