A Multicenter Retrospective Review of Systemic Anti-Cancer Treatment and Palliative Care Provided to Solid Tumor Oncology Patients in the 12 Weeks Preceding Death in Ireland.

BACKGROUND: Systemic anti-cancer treatment (SACT) can improve symptoms and survival in patients with incurable cancer but there may be harmful consequences. Information regarding the use of SACT at the end-of-life and its impact on patients has not been described in Ireland. AIMS: The study aimed to quantify and describe the use of SACT at end-of-life. The primary outcome of interest was the number of patients who received treatment in the last 12, 4 and 2 weeks of life. Secondary outcomes included the frequency of admissions and procedures, location of death, and timing of specialist palliative care (SPC) referral. METHODS: Retrospective review. Fisher exact testing was used for analyses. Patients were included if they died between January 2015 and July 2017 and received at least 1 dose of treatment for a solid tumor malignancy. RESULTS: Five hundred and eighty two patients were included. Three hundred and thirty eight (58%), 128 (22%) and 36 (6%) received treatment in the last 12, 4 and 2 weeks of life respectively. Patients who received chemotherapy in the last 12 weeks of life were more likely to be admitted to hospital, undergo a procedure, and die in hospital than those who did not (P < 0.001 for all). Median time of SPC referral before death was shorter in those patients who received chemotherapy than those who did not (61 v129 days, p = 0.0001). CONCLUSION: Patients who received chemotherapy had a higher likelihood of hospital admission, invasive procedure, and in-hospital death. They were less likely to have been referred early to SPC services.

The role of the melanoma gene MC1R in Parkinson disease and REM sleep behavior disorder.

The MC1R gene, suggested to be involved in Parkinson disease (PD) and melanoma, was sequenced in PD patients (n = 539) and controls (n = 265) from New York, and PD patients (n = 551), rapid eye movement sleep behavior disorder (RBD) patients (n = 351), and controls (n = 956) of European ancestry. Sixty-eight MC1R variants were identified, including 7 common variants with frequency > 0.01. None of the common variants was associated with PD or RBD in the different regression models. In a meta-analysis with fixed-effect model, the p.R160W variant was associated with an increased risk for PD (odds ratio = 1.22, 95% confidence interval = 1.02-1.47, p = 0.03) but with significant heterogeneity (p = 0.048). Removing one study that introduced the heterogeneity resulted in nonsignificant association (odds ratio = 1.11, 95% confidence interval, 0.92-1.35, p = 0.27, heterogeneity p = 0.57). Rare variants had similar frequencies in patients and controls (10.54% and 10.15%, respectively, p = 0.75), and no cumulative effect of carrying more than one MC1R variant was found. The present study does not support a role for the MC1R p.R160W and other variants in susceptibility for PD or RBD.
