Sirolimus, Gemcitabine Hydrochloride, and Cisplatin in Treating Patients At High Risk for Cholangiocarcinoma Recurrence After Liver Transplant or Surgery

PRIMARY OBJECTIVES:

I. Assessment of the percentage of patients who are able to complete therapy through 4 and 6 months post-registration.

SECONDARY OBJECTIVES:

I. To describe the adverse events, rate of dose reductions, and quality of life in these patients.

II. To summarize timed endpoints of time-to-recurrence, disease-free survival, overall survival, time to treatment failure, and time until treatment related grade 3+ adverse events.

OUTLINE:

Patients receive cisplatin intravenously (IV) over 1 hour and gemcitabine hydrochloride IV over 30 minutes on days 1 and 8, and sirolimus orally (PO) daily or three times weekly. Treatment repeats every 3 weeks for up to 8 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for up to 5 years.
