Abstract:
Patients with carcinoma of unknown primary site represent a very heterogeneous clinicopathologic group. Progress has been made in defining important clinical subsets, and specialized pathologic analysis is essential for the poorly differentiated neoplasms. Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is a broad-spectrum antineoplastic agent with demonstrated activity in a wide variety of carcinomas. We have combined paclitaxel with carboplatin and oral etoposide for the therapy of patients with unknown primary carcinoma. The overall response rate (47%, with 13% complete responders) compares favorably with any other chemotherapy. Furthermore, the median survival of 13.4 months was notable and encouraging. Toxicity was well-tolerated and no treatment-related deaths occurred. Additional data are needed to more firmly establish the role of paclitaxel for unknown primary cancer.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy.
