Background
We evaluated the efficacy and feasibility of paclitaxel in patients with gemcitabine-refractory pancreatic cancer. We also evaluated the correlation between tumor marker decline and response rate.
Methods
Thirty patients histologically diagnosed with pancreatic cancer who had undergone paclitaxel treatment as salvage chemotherapy were retrospectively analyzed. Paclitaxel treatment was performed with 80 mg/(m2 week) for 3 weeks followed by 1 week rest, and this was continued until failure. Tumor marker response was evaluated by measuring levels of carbohydrate antigen 19-9, carcinoembryonic antigen, and DUPAN-2 monthly.
Results
In total, 272 weekly paclitaxel treatments were performed. The median number of treatments per patient was 8 (range 1–22). The median overall survival from the start of paclitaxel treatment was 6.7 months (range 1.2–18.8). The response rate was 10% (3/30 patients) and the disease control rate was 46.7% (14/30 patients). Although grade 3 and 4 hematological and non-hematological toxicities were seen in 7 and 6 patients, respectively, adverse events were managed by conservative treatment. We found a significant correlation between the disease control rate and tumor marker decline within 2 months of paclitaxel treatment (P = 0.01). Patients with tumor marker decline tended to survive longer.
Conclusion
Weekly administration of paclitaxel in patients with gemcitabine-refractory pancreatic cancer seems to be well tolerated and can be effective. Paclitaxel treatment should be considered as salvage chemotherapy after gemcitabine failure in patients with good performance status.
