Practice Patterns and Survival in Patients with Resected Pancreatic Ductal Adenocarcinomas (PDAC) — Results from the Multicentre Indian Pancreatic & Periampullary Adenocarcinoma Project (MIPPAP) Study
Journal of gastrointestinal cancer(2023)
摘要
Background There is limited data from India with regard to presentation, practice patterns and survivals in resected pancreatic ductal adenocarcinomas (PDACs). Methods The Multicentre Indian Pancreatic & Periampullary Adenocarcinoma Project (MIPPAP) included data from 8 major academic institutions across India and presents the outcomes in upfront resected PDACs from January 2015 to June 2019. Results Of 288 patients, R0 resection was achieved in 81% and adjuvant therapy was administered in 75% of patients. With a median follow-up of 42 months (95% CI: 39–45), median DFS for the entire cohort was 39 months (95% CI: 25.4–52.5), and median overall survival (OS) was 45 months (95% CI: 32.3–57.7). A separate analysis was done in which patients were divided into 3 groups: (a) those with stage I and absent PNI (SI&PNI-), (b) those with either stage II/III OR presence of PNI (SII/III/PNI+), and (c) those with stage II/III AND presence of PNI (SII/III&PNI+). The DFS was significantly lesser in patients with SII/III&PNI+ (median 25, 95% CI: 14.1–35.9 months), compared to SII/III/PNI + (median 40, 95% CI: 24–55 months) and SI&PNI- (median, not reached) ( p = 0.036)). Conclusions The MIPPAP study shows that resectable PDACs in India have survivals at par with previously published data. Adjuvant therapy was administered in 75% patients. Adjuvant radiotherapy does not seem to add to survival after R0 resection.
