Assessing impact, needs and quality-of-life among informal carers of people with pancreatic cancer, a prospective study: the PAN-CARER study protocol.

INTRODUCTION: Approximately 10 300 people are diagnosed with pancreatic cancer each year in the UK. The cancer and its treatment inflict a significant physical, functional and emotional burden on patients. Research suggests that patients have many ongoing needs for support and care, but that these needs are not met by existing services. Family members often step in to fill this gap and provide support and care during and after treatment. Research in other cancers shows that this informal caregiving can place a very heavy burden on carers. However, there are few studies in the international literature that have focused on informal carers in pancreatic cancer; none have been conducted in the UK. METHODS AND ANALYSIS: Two complementary research methods will be utilised. First, a longitudinal quantitative study of 300 carers investigating, using validated questionnaires to assess the impact of caregiving (Caregiver Reaction Assessment), the unmet needs of carers (Supportive Care Needs Survey) and the quality-of-life (Short Form 12-item health survey), will be conducted. Second, qualitative interviews will be conducted with up to 30 carers to explore their experiences in more depth. Mixed-effects regression models will be applied to survey results to determine how impact, needs and quality-of-life vary over time, compare outcomes between carers of patients with operable and inoperable disease and identify social factors which affect outcomes. Interview data will undergo reflexive thematic analysis. ETHICS AND DISSEMINATION: The protocol has been approved by the Health Research Authority of the UK (Ethical approval IRAS ID 309503). Findings will be published in peer-reviewed journals and presented at national and international conferences.

The Influence of Patients' Age on the Outcome of Treatment for Pancreatic Ductal Adenocarcinoma.

OBJECTIVE: The aim of the study was to determine the impact of age on curative management and outcomes of patients with pancreatic ductal adenocarcinoma. METHODS: Patients who underwent resection for pancreatic ductal adenocarcinoma at 2 units were retrospectively reviewed (between 2005 and 2017) and stratified by age (older patients ≥70 years). Regression analysis was used to explore factors impacting administration of adjuvant chemotherapy and survival. The Kaplan-Meier method was used to estimate overall survival (time from surgery to death). Statistical significance was set at P < 0.05. RESULTS: From 2005 to 2014, 222 patients were identified (<70 years, n = 128; ≥70 years, n = 94). Elderly patients were less likely to receive adjuvant chemotherapy compared with younger patients (odds ratio, 0.57, P = 0.041). Tumor stage, margin, and year of surgery (post-2011 vs pre-2011) were not predictors for chemotherapy receipt (P > 0.05). Frailty was the commonest reason (36.8%) to decline chemotherapy in elderly patients. In patients receiving adjuvant chemotherapy, completion rates (P = 0.32) and overall survival (24 months vs 30 months, P = 0.50) were no different. CONCLUSIONS: Elderly patients demonstrate similar outcomes to younger yet are less likely to commence chemotherapy because of frailty. Holistic preoperative assessment may improve selection for curative treatment.

Current status of minimally invasive necrosectomy for post-inflammatory pancreatic necrosis.

OBJECTIVE: This paper reviews current knowledge on minimally invasive pancreatic necrosectomy. BACKGROUND: Blunt (non-anatomical) debridement of necrotic tissue at laparotomy is the standard method of treatment of infected post-inflammatory pancreatic necrosis. Recognition that laparotomy may add to morbidity by increasing postoperative organ dysfunction has led to the development of alternative, minimally invasive methods for debridement. This study reports the status of minimally invasive necrosectomy by different approaches. METHODS: Searches of MEDLINE and EMBASE for the period 1996-2008 were undertaken. Only studies with original data and information on outcome were included. This produced a final population of 28 studies reporting on 344 patients undergoing minimally invasive necrosectomy, with a median (range) number of patients per study of nine (1-53). Procedures were categorized as retroperitoneal, endoscopic or laparoscopic. RESULTS: A total of 141 patients underwent retroperitoneal necrosectomy, of whom 58 (41%) had complications and 18 (13%) required laparotomy. There were 22 (16%) deaths. Overall, 157 patients underwent endoscopic necrosectomy; major complications were reported in 31 (20%) and death in seven (5%). Laparoscopic necrosectomy was carried out in 46 patients, of whom five (11%) required laparotomy and three (7%) died. CONCLUSIONS: Minimally invasive necrosectomy is technically feasible and a body of evidence now suggests that acceptable outcomes can be achieved. There are no comparisons of results, either with open surgery or among different minimally invasive techniques.

Systematic review of peri-operative nutritional supplementation in patients undergoing pancreaticoduodenectomy.

BACKGROUND: Although nutritional supplementation is established in surgical practice, studies on feeding patients undergoing pancreaticoduodenectomy utilise widely disparate protocols, include small numbers of patients and have disparate endpoints. The aim of this study is to carry out a systematic review of peri-operative nutritional supplementation in patients undergoing pancreaticoduodenectomy in order to identify consistent themes. METHODS: Searches of the MEDLINE and EMBASE databases yielded 10 studies examining nutritional support in 571 patients undergoing pancreaticoduodenectomy. Data were retrieved on: proportion of pre-operative weight loss, biochemical parameters (pre-operative albumin and the presence of jaundice), type and duration of nutritional support and clinical outcome (morbidity, mortality and hospital stay). RESULTS: Pre-operative percentage weight loss was similar in all studies evaluated. Routine post-operative total parenteral nutrition (TPN) was associated with a higher incidence of complications. Enteral nutrition reduced infective complications. Cyclical nutrition was associated with a lower incidence of post-operative gastric stasis. CONCLUSION: Clear themes emerge from this systematic review. Patients undergoing pancreaticoduodenectomy are nutritionally depleted at the time of surgery and the pre-operative period may present a window for intervention. Routine TPN is not beneficial. Routine post-operative enteral nutritional support, delivered on a cyclical basis appears to be the optimal mode of delivery.
