简要总结
RATIONALE: Drugs used in chemotherapy, such as cisplatin, paclitaxel, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known whether chemotherapy and radiation therapy are more effective when given with or without additional chemotherapy in treating cervical cancer.
PURPOSE: This randomized phase III trial is studying chemotherapy and pelvic radiation therapy to see how well they work when given with or without additional chemotherapy in treating patients with high-risk early-stage cervical cancer after radical hysterectomy.
详细描述
OBJECTIVES:
Primary
- To determine if administering adjuvant systemic chemotherapy after chemoradiotherapy will improve disease-free survival compared to chemoradiotherapy alone in patients with high-risk early-stage cervical carcinoma found to have positive nodes and/or positive parametria after radical hysterectomy.
Secondary
- To evaluate adverse events.
- To evaluate overall survival.
- To evaluate quality of life.
- To evaluate chemotherapy-induced neuropathy.
- To perform a post-hoc dose-volume evaluation between patients treated with standard radiotherapy and patients treated with intensity-modulated radiotherapy (IMRT) with respect to toxicity and local control.
- To collect fixed tissue samples to identify tumor molecular signatures that may be associated with patient outcomes, such as adverse events, disease-free survival, and overall survival.
- To collect blood samples to identify secreted factors from serum and plasma that may be associated with adverse events or outcome and to identify single nucleotide polymorphisms (SNPs) in genes from buffy coat that may be associated with a genetic predisposition to tumor formation itself or a response to cytotoxic therapy.

结局指标
主要结局
Disease-free Survival (Percentage of Participants Alive Without Disease)
时间窗: From randomization to first failure (local, regional, or distant metastases failure or death due to any cause) or last follow-up. Maximum follow-up at the time of analysis was 12.8 years. The 2- and 4-year DFS estimates are reported.
Disease-free survival (DFS) is estimated by the Kaplan-Meier method. The distribution of DFS estimates between the two arms is compared using the log rank test. DFS time is measured from the date of randomization to the date of first DFS failure (local, regional or distant metastases failure or death due to any cause) or last follow-up (censored). Analysis was to occur after disease or death was reported for 50 participants.
