Objectives:
We aimed to compare the efficacy and toxicity of palliative chemotherapy in elderly patients with pancreatic ductal adenocarcinoma (PDAC) with those in younger patients.
Methods:
A total of 60 patients with locally advanced or metastatic PDAC who received FOLFIRINOX or nab-paclitaxel plus gemcitabine at our institution from January 2014 to December 2021 were analyzed. Patients 70 years or older were classified into an elderly group.
Results:
The elderly group included 16 patients (26.7%). In the elderly group, nab-paclitaxel plus gemcitabine was used more than FOLFIRINOX compared with the young group (75.0% and 25.0% vs 34.1% and 64.9%, respectively; P = 0.008). The overall survival was not significantly different between the 2 groups (15.6 vs 13.4 months, P = 0.259). However, the elderly group showed better progression-free survival (11.4 vs 7.4 months, P = 0.034). The incidence of adverse events including neutropenia (75.0% vs 81.8%, P = 0.716), thrombocytopenia (25.0% vs 31.3%, P = 0.743), and anemia (50.0% vs 43.2%, P = 0.771) was not different between the 2 groups. Peripheral neuropathy was more common in the elderly group (18.3% vs 2.3%, P = 0.054), though not statistically significant.
Conclusion:
The efficacy and toxicity of chemotherapy in elderly patients with advanced PDAC were comparable with those in younger patients.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
