Oxaliplatin and Capecitabine in the Treatment of Relapsed/Refractory Carcinoma of Unknown Primary Site

A Phase II Trial of Oxaliplatin and Capecitabine in the Treatment of Patients With Relapsed/Refractory Carcinoma of Unknown Primary Site

In this phase II trial, we will evaluate the feasibility and efficacy of the oxaliplatin/capecitabine combination in patients who have had one previous chemotherapy regimen for the treatment of carcinoma of unknown primary site. Patients who are relapsed after a previous response to treatment will be eligible, as well as those who were refractory to first-line therapy.

All patients received treatment with oxaliplatin 130mg/m2, given intravenously on day 1 of each 21 day cycle. Capecitabine 1000mg/m2 PO BID was administered on days 1-14 of each cycle.
