Impact of Neoadjuvant Therapy for Pancreatic Cancer: Transatlantic Trend and Postoperative Outcomes Analysis.

BACKGROUND: The introduction of modern chemotherapy a decade ago has led to increased use of neoadjuvant therapy (NAT) in patients with pancreatic ductal adenocarcinoma (PDAC). A recent North American study demonstrated increased use of NAT and improved operative outcomes in patients with PDAC. The aims of this study were to compare the use of NAT and short-term outcomes in patients with PDAC undergoing pancreatoduodenectomy (PD) among registries from the US and Canada, Germany, the Netherlands, and Sweden. STUDY DESIGN: Databases from 2 multicenter (voluntary) and 2 nationwide (mandatory) registries were queried from 2018 to 2020. Patients undergoing PD for PDAC were compared based on the use of upfront surgery vs NAT. Adoption of NAT was measured in each country over time. Thirty-day outcomes, including the composite measure (ideal outcomes), were compared by multivariable analyses. Sensitivity analyses of patients undergoing vascular resection were performed. RESULTS: Overall, 11,402 patients underwent PD for PDAC with 33.7% of patients receiving NAT. The use of NAT increased steadily from 28.3% in 2018 to 38.5% in 2020 (p < 0.0001). However, use of NAT varied widely by country: the US (46.8%), the Netherlands (44.9%), Sweden (11.0%), and Germany (7.8%). On multivariable analysis, NAT was significantly (p < 0.01) associated with reduced rates of serious morbidity, clinically relevant pancreatic fistulae, reoperations, and increased ideal outcomes. These associations remained on sensitivity analysis of patients undergoing vascular resection. CONCLUSIONS: NAT before PD for pancreatic cancer varied widely among 4 Western audits yet increased by 26% during 3 years. NAT was associated with improved short-term outcomes.

Laparoscopic distal pancreatectomy is more cost-effective than open resection: results from a Swedish randomized controlled trial.

BACKGROUND: Laparoscopic distal pancreatectomy is being implemented worldwide. The aim of this study was to perform a cost-effectiveness analysis from a health care perspective. METHODS: This cost-effectiveness analysis was based on the randomized controlled trial LAPOP, where 60 patients were randomized to open or laparoscopic distal pancreatectomy. For the follow-up of two years, resource use from a health care perspective was recorded, and health-related quality of life was assessed using the EQ-5D-5L. The per-patient mean cost and quality-adjusted life years (QALYs) were compared using nonparametric bootstrapping. RESULTS: Fifty-six patients were included in the analysis. The mean health care costs were lower, €3863 (95% CI: -€8020 to €385), for the laparoscopic group. Postoperative quality of life improved with laparoscopic resection and resulted in a gain in QALYs of 0.08 (95% CI: -0.09 to 0.25). The laparoscopic group had lower costs and improved QALYs in 79% of bootstrap samples. With a cost-per-QALY threshold of €50 000, 95.4% of the bootstrap samples were in favour of laparoscopic resection. CONCLUSION: Laparoscopic distal pancreatectomy is associated with numerically lower health care costs and improvements in QALYs compared with the open approach. The results support the ongoing transition from open to laparoscopic distal pancreatectomies.

Quality of life after open versus laparoscopic distal pancreatectomy: long-term results from a randomized clinical trial.

BACKGROUND: Pancreatic surgery is rapidly transitioning towards minimally invasive methods. Positive results have been published regarding the safety and efficacy of laparoscopic distal pancreatectomy, but postoperative quality of life after operation remains relatively unexplored. The aim of this study was to assess the long-term quality of life after open versus laparoscopic distal pancreatectomy. METHODS: A long-term analysis of quality-of-life data after laparoscopic and open distal pancreatectomy based on the LAPOP trial (a single-centre, superiority, parallel, open-label, RCT in which patients undergoing distal pancreatectomy were randomized 1 : 1 to either the open or laparoscopic approach). Patients received the quality-of-life questionnaires QLQ-C30 and PAN26 before surgery and at 5-6 weeks, 6 months, 12 months, and 24 months after surgery. RESULTS: Between September 2015 and February 2019, a total of 60 patients were randomized, and 54 patients (26 in the open group and 28 in the laparoscopic group) were included in the quality-of-life analysis. A significant difference was observed in six domains in the mixed model analysis, with better results among patients who underwent laparoscopic surgery. At the 2-year measurement, a statistically significant difference between groups was seen in three domains, and a clinically relevant difference of 10 or more was seen in 16 domains, with better results among the patients who underwent laparoscopic resection. CONCLUSION: Considerable differences were shown in postoperative quality of life after laparoscopic compared with open distal pancreatectomy, with better results among the patients who had undergone laparoscopic resection. Of note, some of these differences persisted up to 2 years after surgery. These results strengthen the ongoing transition from open to minimally invasive pancreatic surgery for distal pancreatectomy.

Symptoms and life changes after total pancreatectomy: a qualitative study.

BACKGROUND: Total pancreatectomy (TP) is a major surgical procedure that involves lifelong exocrine and endocrine pancreatic insufficiency. Qualitative evidence is sparse regarding patients' experiences after the operation. The aim of this study was to explore patients' experiences of symptoms that occur after TP and how these symptoms affect their health and life situations. METHODS: A qualitative design with prospective consecutive sampling and an inductive thematic analysis was used. Semistructured interviews were postoperatively performed at 6-9 months with 20 patients undergoing TP in two university hospitals in Sweden. RESULTS: Two main themes emerged from the analysis: "Changes in everyday life" and "Psychological journey". Patients experienced symptoms related to diabetes as the major life change after the operation, and they were also limited by symptoms of exocrine insufficiency, difficulties with food intake and physical weakness. In the psychological journey that patients underwent, the support received from family, friends and the health care system was important. Moreover, patients experienced a general need for more extensive information, especially regarding diabetes. CONCLUSION: Patients experience a lack of sufficient support and education after TP, particularly concerning their diabetes. Further efforts should be undertaken to improve information and the organization of diabetes care for this patient group.

Complications and chemotherapy have little impact on postoperative quality of life after pancreaticoduodenectomy - a cohort study.

BACKGROUND: With the poor prognosis of pancreatic cancer and the high rate of postoperative complications after pancreaticoduodenectomy, it is important to evaluate how the operation affects patients' quality of life. METHODS: This single-centre study included all patients undergoing pancreaticoduodenectomy from 2006 to 2016. Quality of life was measured with two questionnaires preoperatively, and at 6 and 12 months postoperatively. Comparisons between groups were made using a linear mixed models analysis. RESULTS: Of 279 patients planned for pancreaticoduodenectomy, 245 underwent the operation. The postoperative response rates were all 80% or more. Differences were found in one domain between the early and late time periods and three domains between patients receiving and not receiving adjuvant chemotherapy. No significant differences were found between patients with and without severe postoperative complications. However, the demographic variables of age group, sex, preoperative diabetes and smoking all exerted a significant impact on postoperative quality of life. CONCLUSION: While little or no impact was shown for the factors of postoperative complications, time period and adjuvant chemotherapy, demographic data, such as age, sex, preoperative diabetes and smoking, had considerable impacts on postoperative quality of life after pancreaticoduodenectomy.

Preoperative Biliary Drainage Does Not Independently Reduce Survival After Pancreaticoduodenectomy Among Patients With Pancreatic Ductal Adenocarcinoma: A National Registry Study.

Objective: This study aimed to explore a possible relationship between preoperative biliary drainage (PBD) and overall survival in a national cohort of Swedish patients who underwent pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). Background: PBD has been shown to increase postoperative complications after PD, but its use is steadily increasing. There are a few small studies that have indicated that PBD might in itself negatively affect overall survival after PD. Methods: Patients from the Swedish National Registry for tumors in the pancreatic and periampullary region diagnosed from 2010 to 2019 who underwent PD for PDAC were included. Kaplan-Meier curves, log-rank tests and Cox proportional hazards analyses were performed to investigate survival. Results: Out of 15,818 patients in the registry, 3113 had undergone PD, of whom 1471 had a histopathological diagnosis of PDAC. Patients who had undergone PBD had significantly worse survival, but the effect of PBD disappeared in the multivariable analysis when elevated bilirubin at any time was included. Conclusions: PBD does not independently influence survival after PD for PDAC, but this study implies that even a nominally increased preoperative bilirubin level might impair long-term survival.

There Is No Increase in Perioperative Mortality After Pancreaticoduodenectomy in Octogenarians: Results From the Swedish National Registry for Tumors in the Pancreatic and Periampullary Region.

Objective: The aim of this observational study was to compare postoperative mortality and complications between octogenarians and younger patients following pancreaticoduodenectomy (PD). Summary Background Data: With the growing elderly population and improved operative and postoperative results, PD is performed more frequently in octogenarians. Despite recent studies, it is uncertain whether elderly patients experience worse postoperative outcomes than younger patients. Methods: All patients registered in the Swedish National Registry for tumors in the pancreatic and periampullary region from 2010 to 2018 who underwent PD were included in the analysis. Results: Out of 13,936 patients included in the registry, 2793 patients underwent PD and were divided into the following age groups: <70 (n = 1508), 70-79 (n = 1137), and ≥80 (n = 148) years old. There was no significant difference in in-hospital, 30- or 90-day mortality among groups. The 2 older groups had a higher rate of medical and some surgical complications but not a significantly higher rate of complications ≥IIIa according to the Clavien-Dindo classification system. The 2 older groups had lower body mass index, higher American Society of Anesthesiologists and Eastern Cooperative Oncology Group scores, lower smoking rates, and a higher rate of preoperative biliary drainage than the <70-year-old group (all P < 0.001). The operation time was shorter in the oldest group. Conclusions: Despite the worse preoperative condition of octogenarians than younger patients, short-term mortality and serious complications were not increased. The shorter operation time, however, may indicate that patients in the oldest group were more strictly selected. With careful preoperative consideration, especially regarding cardiovascular morbidity, more octogenarians can potentially be safely offered PD.
