Sumario:INTRODUCTION: To report response rates, progression-free survival (PFS) and overall survival (OS) in patients with advanced pancreatic cancer treated with different available chemotherapeutic regimens over 10 years. MATERIALS AND METHODS: This is a retrospective observational study. All patients with locally advanced and metastatic pancreatic cancer (MPC) at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, from January 2008 to December 2017 were studied. Data were collected from the hospital information system. The characteristics and outcomes of all the patients were analysed. PFS and OS were also estimated. Kaplan–Meier curves and log-rank test were applied, and SPSS version 20 was used for data analysis. RESULTS: Eighty-seven subjects with a median age of 56 years (range 21–76) were included. Sixty-two (71%) subjects were male. The most common tumour location was the head of the pancreas in 46 (53%) of all the subjects. Sixty-three (72%) subjects had elevated carbohydrate antigen-19.9 values. About 47 (54%) subjects had locally advanced pancreatic cancer (LAPC), and 40 (46%) subjects had MPC. Chemotherapy regimens used were FOLFIRINOX in 23 (26%), gemcitabine (GEM) based in 66 (65%) and capecitabine (CAP) based in 8 (9%) of the subjects. One (1%) subject had a complete response, 12 (14%) had a partial response, 10 (11%) had stable disease and 59 (68%) of the subjects had progressive disease. The objective response rate (ORR) was 15% and the disease control rate (DCR) was 26%. In MPC, the ORR was 10%, DCR was 18% and tumour progression was seen in 72% of the patients, while in LAPC, the ORR was 19.1, DCR 34% and tumour progression was documented in 64% of the patients, respectively. The FOLFIRINOX chemotherapy regimen had better ORR, DCR and lesser number of progressions as compared to GEM- and CAP-based chemotherapy regimens. The median PFS of the whole group was 32 weeks, and the median OS was 54 weeks. The PFS was significantly higher for LAPC (39 weeks) as compared to the MPC group (25 weeks) (P = 0.028). There was no statistically significant difference between the OS of these two groups (P = 0.451). In addition, PFS was significantly higher with FOLFIRINOX chemotherapy as compared to the other chemotherapy regimens. Regarding OS, there was no statistically significant difference among all chemotherapy regimen groups (P = 0.267). CONCLUSION: Based on our results, FOLFIRINOX remained the most effective chemotherapy regimen despite the dose modifications and toxicities in all groups, indicating that modified FOLFIRINOX could be considered as a first-line regimen in Southeast Asian population.
