Abstract:
Eighty-nine patients with FIGO stages 3 and 4 epithelial ovarian cancer who responded to cis-platinum alone or cis-platinum containing combinations have been studied retrospectively to determine the time taken to achieve maximum tumour response. Clinically determined partial and complete responses were seen within 2-6 (median 3) treatment courses and 2-5 (median 3) treatment courses respectively. Sixty-nine patients were restaged surgically demonstrating partial and complete response within 4-12 (median 5) and 3-16 (median 5) treatment courses respectively. After the initial 6 courses of chemotherapy, 53 patients showing a partial response continued with the same drugs but only 1 patient ultimately achieved a surgically confirmed complete response. Since second line drugs rarely achieve complete response following tumour progression we propose that patients who have only achieved partial response following 6 treatment courses should change chemotherapy in an attempt to achieve complete response.

Cancer Therapies
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. Some cancer cells respond to one...
