    Abstract:
    OBJECTIVES: To determine the maximum tolerated dose (MTD) of weekly paclitaxel and cisplatin chemotherapy concurrent with whole pelvic irradiation in women with locally advanced cervical cancer. METHODS: Consenting patients with stage IB2, IIA, IIB, IIIB and IVA carcinoma of the cervix (all cell types) were eligible for this phase I/II trial. Chemotherapy agents were administered in escalating doses to cohorts of three patients at each dose level, pending evaluation of toxicities from the previous dose level. RESULTS: Thirty-five eligible women were enrolled on this study, of whom 13 comprised the phase I component. The MTD was determined to be cisplatin 40 mg/m2 and paclitaxel 40 mg/m2 administered weekly for six cycles with external beam radiation therapy. An additional 21 patients were enrolled in the phase II component at the previously determined MTD, yielding a total of 22 patients at the MTD, of whom 19 were evaluable. Among the evaluable patients treated at the MTD, two had grade 3 or 4 gastrointestinal (GI) toxicities (representing 5 of 113 cycles administered to this cohort) and seven experienced grade 3 or 4 neutrophil toxicity, none occurring prior to the fourth cycle. Thrombocytopenia was rare. Radiation therapy was successfully completed in 52% of patients at 8 weeks and in 79% of patients at 9 weeks, with a median of 59 days. CONCLUSIONS: Paclitaxel and cisplatin combination chemotherapy concurrent with whole pelvic irradiation can be safely administered at the described MTD.
