Abstract:
BACKGROUND:Cisplatin (CDDP) administration concomitant with radiotherapy (RT) for the treatment of locally advanced cervical cancer has evolved from an inpatient 5-day every 21-day regimen to a weekly outpatient regimen. This study was designed to test for differences in progression-free survival (PFS) and toxicity between the 2 regimens. METHODS:In all, 77 consecutive patients at a single institution with stage IB2-IV cervical cancer were included in this analysis (using the International Federation of Gynecologists and Obstetricians staging system). All patients were treated with CDDP, external beam RT, and 2 9-Gy high-dose-rate brachytherapy treatments. Two cohorts were compared: 1) 5-day, patients treated from 1995 to 2001 with CDDP 20 mg/m(2) x 5 days every 21 days concomitant with RT; 2) weekly, treated after May 2001 with CDDP 40 mg/m(2) weekly concomitant with RT. RESULTS:In all, 50 patients were treated with the 5-day regimen and 27 patients with the weekly regimen. There were no significant demographic differences between the groups. Overall 3-year PFS, controlling for stage, was 90% and 76% for 5-day and weekly groups, respectively (P = .01). Adjusting for stage, age, and completion of treatment, the risk of treatment failure among the weekly group was 3.46 times higher than the 5-day group (P = .02). The weekly group had a 3.43 times higher risk of developing acute toxicities than the 5-day group (P = .02) in advanced-stage patients. CONCLUSIONS:Patients who received weekly CDDP have a shorter 3-year PFS. Patients with advanced-stage cervical cancer who received weekly CDDP had significantly more acute toxicities. These data should be confirmed in a multi-institutional, randomized, controlled study.
