A phase II trial of gemcitabine and capecitabine in patients with unresectable or metastatic gallbladder cancer or cholangiocarcinoma: Southwest Oncology Group study S0202.

ABSTRACT: Patients with gallbladder cancer or cholangiocarcinoma were treated with the combination of gemcitabine 1,000 mg/m(2) IV over 100 min on days 1 and 8 and capecitabine 650 mg/m(2) BID PO on days 1-14, administered every 21 days.The primary objective of this study was to assess the response rate (confirmed complete and partial responses) of gemcitabine and capecitabine used in advanced/metastatic biliary neoplasms. Secondary objectives included overall survival and toxicities.The study accrued 57 patients from September 2003 to April 2005. Three patients were ineligible, and two others received no treatment. Characteristics of analyzable patients: 35 (67%) cholangiocarcinoma, 17 (33%) gallbladder cancer; PS 0 (18 pts), 1 (26 pts), 2 (8 pts); 26 (50%) men; median age 58.8 years (29.5-85.6). Among 51 patients evaluated for toxicity, 6 experienced grade 4 toxicities. Among 52 patients, there were 7 confirmed partial responses for a confirmed response probability of 13% (95% CI: 6-26%). Six patients had an unconfirmed partial response for an overall response probability of 25% (95% CI: 14-39%). Twelve patients (23%) demonstrated stable disease. The 6-month overall survival was 55% (95% CI: 41-69%), and median survival was 7 months (95% CI: 5-8 months).The combination of gemcitabine and capecitabine is a well-tolerated regimen with activity in patients with advanced gallbladder cancer and cholangiocarcinoma.

Project description:Hilar cholangiocarcinoma (CCA) is a difficult malignancy to treat surgically because of its anatomical location and its frequent association with primary sclerosing cholangitis. Neoadjuvant chemoradiotherapy followed by liver transplantation in lymph node-negative patients has been advanced by select liver transplant centers for the treatment of patients with unresectable disease. This approach has most commonly used external-beam radiotherapy in combination with biliary brachytherapy and 5-fluorouracil-based chemotherapy. Our center recently embarked on a protocol using stereotactic body radiation therapy (SBRT) followed by capecitabine in lymph node-negative patients until liver transplantation. We, therefore, retrospectively determined the tolerability and pathological response in this pilot study. During a 3-year period, 17 patients with unresectable hilar CCA were evaluated for treatment under this protocol. In all, 12 patients qualified for neoadjuvant therapy and were treated with SBRT (50-60 Gy in 3-5 fractions over the course of 2 weeks). After 1 week of rest, capecitabine was initiated at 1330 mg/m(2) /day, and it was continued until liver transplantation. During neoadjuvant therapy, there were 35 adverse events in all, with cholangitis and palmar-plantar erythrodysesthesia being the most common. Capecitabine dose reductions were required on 5 occasions. Ultimately, 9 patients were listed for transplantation, and 6 patients received a liver transplant. The explant pathology of hilar tumors showed at least a partial treatment response in 5 patients, with extensive tumor necrosis and fibrosis noted. Additionally, high apoptotic indices and low proliferative indices were measured during histological examinations. Eleven transplant-related complications occurred, and the 1-year survival rate after transplantation was 83%. In this pilot study, neoadjuvant therapy with SBRT, capecitabine, and liver transplantation for unresectable CCA demonstrated acceptable tolerability. Further studies will determine the overall future efficacy of this therapy.
