p53 Gene Status and Response to Platinum/Paclitaxel-Based Chemotherapy in Advanced Ovarian Carcinoma

Abstract

In contrast to the limited efficacy of treatment with paclitaxel in combination with standard platinum doses against wild-type p53 ovarian tumors, patients with mutant p53 ovarian tumors were more responsive to paclitaxel-based chemotherapy. The pattern of response to chemotherapy containing paclitaxel is different from that associated with high-dose cisplatin therapy. Determining p53 mutational status can be useful in predicting therapeutic response to drugs effective in ovarian carcinoma.
