Background: Adjuvant chemotherapy or chemoradiation is often recommended for resected pancreatic adenocarcinoma. We sought to examine the impact of these therapies on R1 resected pancreatic cancer.
Methods: Utilizing the National Cancer Database we identified patients who underwent pancreatic resection for adenocarcinoma. Patients were stratified by resection status and adjuvant therapy.
Results: We identified 28,440 patients who underwent pancreatic resection. Patients with tumor size >2 cm were more likely to undergo R1 resections, p < 0.001. Adjuvant therapy improved survival in all patients with median and 5-year survival: adjuvant chemotherapy (21.7 months, 17.45%), chemoradiation (23.3 months, 20.9%) vs no adjuvant therapy (19.5 months, 19.1%), p < 0.001. In the R1 resection cohort survival was also improved with adjuvant therapy with chemoradiation demonstrating the most significant improvement: adjuvant chemotherapy (15.9 months, 6.5%), chemoradiation (18.7 months, 11.2%) vs no adjuvant therapy (12.5 months, 8.7%), p < 0.001. Chemoradiation but not adjuvant chemotherapy improved survival in the R1 node negative, p < 0.004, and node positive, p < 0.001. Adjuvant chemotherapy benefited survival in R1 node positive patients, p < 0.001.
Conclusions: Patients with pancreatic cancer who undergo R1 resection have significant improvement in survival when treated with adjuvant chemoradiation and adjuvant chemotherapy. However, benefits were greater in those receiving adjuvant chemoradiation.

Pancreatic cancer is influenced by interactions between cancer cells and the tumor microenvironment (TME), including tumor-infiltrating lymphocytes (TILs). Specifically, CD8 + T cells impact prognosis by eliminating cancer cells. Recent studies have revealed that microbiomes are present in pancreatic tissues and may affect tumor growth and immune responses.

Background: Radical resection is the only curative method for patients with pancreatic adenocarcinoma (PDAC). However, nearly 85% of PDAC patients suffer from local or distant recurrence within 5 years after curative resection. The progression of recurrent lesions accelerates the mortality rate in PDAC patients.

Background: Although resection is generally necessary for curative-intent treatment of most solid organ cancers, surgery is occasionally aborted due to intraoperative findings. Following aborted cancer surgery, patients have unique care needs that specialized palliative care (PC) providers may be best equipped to manage. We hypothesized that early ambulatory PC referral following aborted cancer surgery would be feasible and acceptable.

Background: The use of minimally invasive (laparoscopic and robotic) pancreatoduodenectomy (PD) is being increasingly adopted despite the lack of hard evidence to support its utilisation. With recent randomised controlled trials (RCTs) comparing open pancreatoduodenectomy (OPD) with robotic or laparoscopic pancreatoduodenectomy (RPD or LPD), we undertook a network meta-analysis (NMA) comparing all 3 approaches to evaluate comparative outcomes.
Methods: A systematic search of MEDLINE, EMBASE, and Cochrane CENTRAL was conducted up to May 2024 and relevant RCTs were identified.

Objective: The present study aimed to evaluate the safety of the first wearable augmented reality assistance system (ARAS) specifically designed for pancreatic surgery and its impact on perioperative outcomes.
Background: Pancreatic surgery remains highly complex and is associated with a high rate of perioperative complications. ARAS, as an intraoperative assistance system, has the potential to reduce these complications.
