Abstract
BACKGROUND Studies have demonstrated that the learning curve plays an important role in robotic pancreatoduodenectomy (RPD). Although improved short-term outcomes of RPD after the learning curve have been reported compared to open pancreatoduodenectomy (OPD), there is a lack of long-term survival analyses. METHODS Patients who underwent curative intended RPD and OPD for pancreatic duct adenocarcinoma (PDAC) between January 2017 and June 2020 were retrospectively reviewed. A 1:2 propensity score matching (PSM) analysis was performed to balance the baseline characteristics between the RPD and OPD groups. RESULTS Of the 548 patients (108 RPD and 440 OPD), 103 RPD patients were matched with 206 OPD patients after PSM. There were 194 (62.8%) men and 115 (37.2%) women, with a median age of 64 (58-69) years. The median overall survival (OS) in the RPD group was 33.2 months compared with 25.7 months in the OPD group (p = 0.058, log-rank). The median disease-free survival (DFS) following RPD was longer than the OPD (18.5 vs. 14.0 months, p = 0.011, log-rank). The RPD group has a lower incidence of local recurrence compared the OPD group (36.9% vs. 51.2%, p = 0.071). Multivariate Cox analysis demonstrated that RPD was independently associated with improved OS (HR 0.70, 95% CI 0.52-0.94, p = 0.019) and DFS (HR 0.66, 95% CI 0.50-0.88, p = 0.005). CONCLUSION After the learning curve, RPD had improved oncologic outcomes in PDAC patients compared to OPD. Future prospective randomized clinical trials will be required to validate these findings.

Kirkegård J, Ladekarl M, Lund A, Mortensen F. Impact on Survival of Early Versus Late Initiation of Adjuvant Chemotherapy After Pancreatic Adenocarcinoma Surgery: A Target Trial Emulation. Ann Surg Oncol 2024; 31:1310-1318. [PMID: 37914923 PMCID: PMC10761389 DOI: 10.1245/s10434-023-14497-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Accepted: 10/10/2023] [Indexed: 11/03/2023]
Abstract
BACKGROUND We examined the impact of early (0-4 weeks after discharge) versus late (> 4-8 weeks after discharge) initiation of adjuvant chemotherapy on pancreatic adenocarcinoma survival. METHODS We used Danish population-based healthcare registries to emulate a hypothetical target trial using the clone-censor-weight approach. All eligible patients were cloned with one clone assigned to 'early initiation' and one clone assigned to 'late initiation'. Clones were censored when the assigned treatment was no longer compatible with the actual treatment. Informative censoring was addressed using inverse probability of censoring weighting. RESULTS We included 1491 patients in a hypothetical target trial, of whom 32.3% initiated chemotherapy within 0-4 weeks and 38.3% between > 4 and 8 weeks after discharge for pancreatic adenocarcinoma surgery; 206 (13.8%) initiated chemotherapy after > 8 weeks, and 232 (15.6%) did not initiate chemotherapy. Median overall survival was 30.4 and 29.9 months in late and early initiators, respectively. The absolute differences in OS, comparing late with early initiators, were 3.2% (95% confidence interval [CI] - 1.5%, 7.9%), - 0.7% (95% CI - 7.2%, 5.8%), and 3.2% (95% CI - 2.8%, 9.3%) at 1, 3, and 5 years, respectively. Late initiators had a higher increase in albumin levels as well as higher pretreatment albumin values. CONCLUSIONS Postponement of adjuvant chemotherapy up to 8 weeks after discharge from pancreatic adenocarcinoma surgery is safe and may allow more patients to receive adjuvant therapy due to better recovery.
