Carcinoma of Unknown Primary Site: Sequential Treatment with Paclitaxel/Carboplatin/Etoposide and Gemcitabine/Irinotecan: A Minnie Pearl Cancer Research Network Phase II Trial

Abstract

Sequential combination chemotherapy with paclitaxel/carboplatin/oral etoposide and gemcitabine/irinotecan is an active treatment for patients with carcinoma of unknown primary site, but overall toxicities are greater than those seen with other combinations of new drugs and survival appears similar to that observed in 264 other patients treated in our four previous phase II trials. A better understanding of the biology of these heterogeneous tumors will likely lead to improved therapy for these patients.
