A cohort study of the recovery of health and wellbeing following colorectal cancer (CREW study): protocol paper

Background: the number of people surviving colorectal cancer has doubled in recent years. While much of the literature suggests that most people return to near pre-diagnosis status following surgery for colorectal cancer, this literature has largely focused on physical side effects. Longitudinal studies in colorectal cancer have either been small scale or taken a narrow focus on recovery after surgery. There is a need for a comprehensive, long-term study exploring all aspects of health and wellbeing in colorectal cancer patients. The aim of this study is to establish the natural history of health and wellbeing in people who have been treated for colorectal cancer. People have different dispositions, supports and resources, likely resulting in individual differences in restoration of health and wellbeing. The protocol described in this paper is of a study which will identify who is most at risk of problems, assess how quickly people return to a state of subjective health and wellbeing, and will measure factors which influence the course of recovery. Methods: this is a prospective, longitudinal cohort study following 1000 people with colorectal cancer over a period of two years, recruiting from 30 NHS cancer treatment centres across the UK. Questionnaires will be administered prior to surgery, and 3, 9, 15 and 24 months after surgery, with the potential to return to this cohort to explore on-going issues related to recovery after cancer. Discussion: outcomes will help inform health care providers about what helps or hinders rapid and effective recovery from cancer, and identify areas for intervention development to aid this process. Once established the cohort can be followed up for longer periods and be approached to participate in related projects as appropriate and subject to funding<br/

Abnormal P300 in people with high risk of developing psychosis

Background Individuals with an “at-risk mental state” (or “prodromal” symptoms) have a 20–40% chance of developing psychosis; however it is difficult to predict which of them will become ill on the basis of their clinical symptoms alone. We examined whether neurophysiological markers could help to identify those who are particularly vulnerable. Method 35 cases meeting PACE criteria for the at-risk mental state (ARMS) and 57 controls performed an auditory oddball task whilst their electroencephalogram was recorded. The latency and amplitude of the P300 and N100 waves were compared between groups using linear regression. Results The P300 amplitude was significantly reduced in the ARMS group [8.6 ± 6.4 microvolt] compared to controls [12.7 ± 5.8 microvolt] (p < 0.01). There were no group differences in P300 latency or in the amplitude and latency of the N100. Of the at-risk subjects that were followed up, seven (21%) developed psychosis. Conclusion Reduction in the amplitude of the P300 is associated with an increased vulnerability to psychosis. Neurophysiological and other biological markers may be of use to predict clinical outcomes in populations at high risk

What is different about living alone with cancer in older age? A qualitative study of experiences and preferences for care

Background: Increasing numbers of older patients with advanced cancer live alone but there is little research on how well health services meet their needs. The aim of this study was to compare the experiences and future preferences for care between two groups of older people with cancer in their last year of life; those who live alone, and those who live with co-resident carers. Methods: In-depth qualitative interviews were conducted with 32 people aged between 70 and 95 years who were living with cancer. They were recruited from general practices and hospice day care, when the responsible health professional answered no to the question, of whether they would be surprised if the patient died within twelve months. Twenty participants lived alone. Interviews were recorded and transcribed and the data analysed using a Framework approach, focussing on the differences and commonalities between the two groups. Results: Many experiences were common to all participants, but had broader consequences for people who lived alone. Five themes are presented from the data: a perception that it is a disadvantage to live alone as a patient, the importance of relational continuity with health professionals, informal appraisal of care, place of care and future plans. People who lived alone perceived emotional and practical barriers to accessing care, and many shared an anxiety that they would have to move into a care home. Participants were concerned with remaining life, and all who lived alone had made plans for death but not for dying. Uncertainty of timescales and a desire to wait until they knew that death was imminent were some of the reasons given for not planning for future care needs. Conclusions: Older people who live alone with cancer have emotional and practical concerns that are overlooked by their professional carers. Discussion and planning for the future, along with continuity in primary care may hold the key to enhancing end-of-life care for this group of patients

The Palliative Care Research Society in the UK

One of the things that distinguished St. Christopher’s Hospice from previous homes for dying patients was Dame Cicely Saunders’ emphasis on research, and on developing a robust evidence base for care of the dying. Good palliative care research is still needed to increase our understanding of the nature and aetiology of the physical, psychological, social and spiritual problems encountered by patients and families, to test the effectiveness of pharmacological and nonpharmacological interventions in addressing these problems, and to evaluate models of service delivery

What to eat when off treatment and living with involuntary weight loss and cancer: a systematic search and narrative review

Purpose: the aim of this study was to report a systematic search and narrative review of the evidence base that can inform dietary advice for patients off treatment living with cancer cachexia syndrome (CCS).Methods: searches were conducted in MEDLINE, EMBASE, PsycINFO and CINAHL databases for publications about diet and cancer patients off treatment with symptoms of CCS. The following limits were applied: English language, from September 1998 to September 2008 and adults. In addition, a hand search included the reference lists of papers identified. Seven hundred and eighteen abstracts were assessed against inclusion/exclusion criteria and 88 were selected for full text independent examination by two researchers. Information from 48 papers was extracted, quality assessed, thematically analyzed and presented as a narrative synthesis.Results: two dominant perspectives emerged on what should be eaten by weight-losing cancer patients. The majority of authors advocated a nutrient-dense diet, facilitated by nutritional counselling. The alternative approach was to advise the patient to ‘eat what they want’. There is little robust evidence to justify either approach as able to deliver on the range of physical and psychosocial objectives that they aim to achieve.Conclusion: new model for the delivery of nutritional care may benefit cancer patients (off treatment) living with weight loss. The proposed model integrates the two identified perspectives to facilitate optimal food intake taking into account the patient's (1) disease symptoms and treatment side effects (2) emotional adaptation to illness and (3) social circumstances. Research is needed to establish which of these obstacles to eating can be changed for which patient groups to improve patient outcome
