Second-Line Treatment for Advanced Pancreatic Adenocarcinoma: Is There a Role for Gemcitabine?
- 32 Downloads
Advanced pancreatic adenocarcinoma (PA) is an aggressive disease that has poor prognosis and frequently interferes with patient’s quality of life. There has been progress in first-line regimens; however, there is no standard second-line regimen. The aim of this study is to analyze second-line gemcitabine after first-line fluorouracil (FU) + leucovorin (LV) + irinotecan + oxaliplatin (FOLFIRINOX) regimen.
This study included consecutive patients with advanced PA treated at Hospital Sirio-Libanês from 2011 to 2016. The patients received FOLFIRINOX as first-line treatment and upon progression, received gemcitabine alone. Survival analysis was performed using the Kaplan-Meier method.
A total of 54 patients were evaluated. Most patients were male (61.1%) and most had an ECOG performance status of 0 or 1 prior to the beginning of second-line treatment (66.6%). The mean number of gemcitabine cycles was 3.4. Most patients had disease progression as the best response to treatment (75.9%), 11.1% had stable disease, and 9.3% experienced a partial response. The median progression-free survival was 1.7 months, and the median overall survival was 6.8 months.
Gemcitabine alone did not show meaningful clinical benefit as second-line treatment after FOLFIRINOX.
