The platinum compounds and paclitaxel in the management of carcinomas of the endometrium and uterine cervix.

Thigpen T, Vance RB, Khansur T

Abstract:

Endometrial carcinoma and squamous cell carcinoma of the cervix are common invasive neoplasms of the female genital tract. Early diagnosis of a majority of patients has resulted in high cure rates for both diseases. In the last two decades, a growing number of active systemic drugs have been identified. Cisplatin has been extensively studied in both neoplasms and has clear activity (20% response rate in endometrial carcinoma and 23% response rate in squamous cell carcinoma of the cervix). Recently, paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has been shown to be clearly active in both (35% response rate in endometrial carcinoma and 17% response rate in squamous cell carcinoma of the cervix). The apparent clinical non-cross-resistance between paclitaxel and cisplatin in other neoplasms like ovarian carcinoma makes combinations including these two agents of great interest. In endometrial carcinoma, a phase I trial of cisplatin plus doxorubicin plus escalating paclitaxel doses is being performed by the Gynecologic Oncology Group (GOG). Based on the outcome of this study, a future randomized trial will compare the current standard, doxorubicin plus cisplatin, with either a combination of cisplatin, doxorubicin, and paclitaxel or a two-drug regimen of paclitaxel plus cisplatin. In squamous cell carcinoma of the cervix, a logical approach to the incorporation of paclitaxel into front-line therapy for advanced or recurrent disease is a phase III trial of the best regimen from GOG protocol 110 (cisplatin with or without either ifosfamide or dibromodulcitol) versus the same drugs plus paclitaxel. In addition, the GOG is conducting a phase I trial of paclitaxel given concomitantly with radiation in the hope that the resulting regimen will be an arm of a future randomized study in patients with locoregionally advanced disease (stages IIB through IVA). The ultimate role of paclitaxel in the management of patients with these two neoplasms awaits the results of these efforts. (25 Refs)
