OBJECTIVE
This study examined the effect of systemic chemotherapy with gemcitabine (GEM) on survival in elderly patients (aged > or = 70 years) with unresectable biliary tract cancer as compared with best supportive care (BSC).
METHODS
We conducted a retrospective study of consecutive patients with unresectable biliary tract cancer administered GEM (800-1,000 mg/m2) on days 1, 8 and 15 every 4 weeks as a first-line treatment. Eligibility included age 70 years and over, and bile duct carcinoma or gallbladder cancer.
RESULTS
Twenty-eight patients were enrolled: 13 (46.4%) received chemotherapy with GEM and 15 (53.6%) received BSC. No cases of complete or partial response were observed. Stable and progressive disease was observed in 9 (69.2%) and 2 patients (15.4%), respectively. Disease control rate was 69.2%. The median overall survival time of patients treated with GEM and BSC was 9.1 and 2.9 months, and the 1-year survival rates were 15.4% and 6.7%, respectively. Grade 3/4 neutropenia occurred in three (23.1%), leukopenia in two (15.4%) and anemia in one patient (7.7%). Grade 3 non-hematologic toxicities were constipation (7.7%) and fatigue (7.7%).
CONCLUSIONS
Chemotherapy with single-agent GEM is a safe and well tolerated regimen for elderly patients with unresectable biliary tract cancer.
