A randomized trial of 13-Cis retinoic acid in children with advanced neuroblastoma after high-dose therapy

One hundred and seventy-five children with Stage 3 or 4 neuroblastoma who had obtained a good response to conventional therapy were randomly allocated to 13-Cis retinoic acid at a dose of 0.75 mg/kg/day or placebo for up to 4 years. Toxicity was mild but no advantage in event-free survival was shown for the children receiving retinoic acid. © 2000 Cancer Research Campaig

How well do we currently care for our dying patients in acute hospitals: the views of the bereaved relatives?

Background The National Care of the Dying Audit—Hospitals (NCDAH) is used as a method to evaluate care for dying patients in England. An additional component to the 2013/2014 audit was the Local Survey of Bereaved Relatives Views using the ‘Care Of the Dying Evaluation’ (CODE) questionnaire. Aim Within the context of the NCDAH audit, to evaluate quality of care provided to dying patients and their families in acute hospitals from the perspective of bereaved relatives. Design Postbereavement survey to bereaved relatives. Setting/participants For acute hospitals wishing to participate, consecutive ‘expected’ adult deaths occurring between 1 May and 30 June 2013 were identified and the CODE questionnaire was sent to the next-of-kin. Results From 3414 eligible next-of-kin, 95 (2.8%) were excluded due to being involved in a complaint procedure and 1006 (29.5%) due to insufficient next-of-kin details. From the remaining 2313 potential participants, 858 returned a completed CODE questionnaire (37.1% response rate). Generally, symptoms were perceived to be well controlled with 769 (91%) participants reporting that either no pain was present or only there ‘some of the time’. Unmet information needs, however, was a recognised area for improvement, for example, 230 (29%) reporting having a discussion about hydration would have been beneficial. Conclusions Adopting a postbereavement survey to NCDAH appears to be feasible, acceptable and a valuable addition. On the whole, the majority of participants reported good or excellent care. A small but significant minority, however, perceived poor quality of patient care with clear and timely communication urgently needed

Collecting biological material from palliative care patients in the last weeks of life: a feasibility study

Objective To assess the feasibility of prospectively collecting biological samples (urine) from palliative care patients in the last weeks of life. Setting A 30-bedded specialist hospice in the North West of England. Participants Participants were adults with a diagnosis of advanced disease and able to provide written informed consent. Method Potential participants were identified by a senior clinician over a 12-week period in 2014. They were then approached by a researcher and invited to participate according to a developed recruitment protocol. Outcomes Feasibility targets included a recruitment rate of 50%, with successful collection of samples from 80% who consented. Results A total of 58 patients were approached and 33 consented (57% recruitment rate). Twenty-five patients (43%) were unable to participate or declined; 10 (17%) became unwell, too fatigued, lost capacity, died or were discharged home; and 15 (26%) refused, usually these patients had distressing pain, low mood or profound fatigue. From the 33 recruited, 20 participants provided 128 separate urine samples, 12 participants did not meet the inclusion criteria at the time of consent and 1 participant was unable to provide a sample. The criterion for a urinary catheter was removed for the latter 6 weeks. The collection rate during the first 6 weeks was 29% and 93% for the latter 6 weeks. Seven people died while the study was ongoing, and another 4 participants died in the following 4 weeks. Conclusions It is possible to recruit and collect multiple biological samples over time from palliative care patients in the last weeks and days of life even if they have lost capacity. Research into the biological changes at the end of life could develop a greater understanding of the biology of the dying process. This may lead to improved prognostication and care of patients towards the end of life

GC-MS Techniques Investigating Potential Biomarkers of Dying in the Last Weeks with Lung Cancer

Predicting when a patient with advanced cancer is dying is a challenge and currently no prognostic test is available. We hypothesised that a dying process from cancer is associated with metabolic changes and specifically with changes in volatile organic compounds (VOCs). We analysed urine from patients with lung cancer in the last weeks of life by headspace gas chromatography mass spectrometry. Urine was acidified or alkalinised before analysis. VOC changes in the last weeks of life were identified using univariate, multivariate and linear regression analysis; 12 VOCs increased (11 from the acid dataset, 2 from the alkali dataset) and 25 VOCs decreased (23 from the acid dataset and 3 from the alkali dataset). A Cox Lasso prediction model using 8 VOCs predicted dying with an AUC of 0.77, 0.78 and 0.85 at 30, 20 and 10 days and stratified patients into a low (median 10 days), medium (median 50 days) or high risk of survival. Our data supports the hypothesis there are specific metabolic changes associated with the dying. The VOCs identified are potential biomarkers of dying in lung cancer and could be used as a tool to provide additional prognostic information to inform expert clinician judgement and subsequent decision making
