Gemcitabine and carboplatin in second-line ovarian cancer.

Most patients with advanced ovarian cancer achieve a clinical complete remission following cytoreductive surgery and chemotherapy with paclitaxel plus carboplatin. However, a majority of these patients will ultimately recur, and second-line treatment for this group of patients is an important aspect of management of this disease as well as an area of active clinical investigation. Until recently, for patients with platinum-sensitive ovarian cancer (more than 6-month disease-free interval), chemotherapy with single-agent carboplatin was frequently recommended. However, two recent prospective randomized trials have shown that combination chemotherapy produces higher response rates and improvement in progression-free survival compared with treatment with single-agent carboplatin. One trial compared treatment with paclitaxel plus a platinum compound with re-treatment with platinum, and a second trial compared carboplatin plus gemcitabine re-treatment against carboplatin in patients with platinum-sensitive recurrent ovarian cancer. Both trials showed a 3-month improvement in progression-free survival in patients treated with the combination, as well as acceptable toxicity. In the absence of a prospective randomized trial comparing these two regimens in patients with platinum-sensitive recurrent ovarian cancer, the choice of which combination to use may depend on toxicity considerations.
