简要总结
RATIONALE: Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some find tumor cells and kill them or carry tumor-killing substances to them. Others interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as cisplatin and fluorouracil, 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. Cetuximab may help cisplatin and fluorouracil work better by making tumor cells more sensitive to the drugs. It may also make tumor cells more sensitive to radiation therapy. Giving cetuximab together with chemotherapy and radiation therapy may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving cetuximab together with cisplatin, fluorouracil, and radiation therapy works in treating immunocompetent patients with stage I (closed to accrual as of 11/3/2008), stage II, (some stage II closed to accrual as of 11/3/2008) or stage III anal cancer.
详细描述
OBJECTIVES:
Primary Objective:
- Determine whether the addition of cetuximab to combined modality therapy (CMT) comprising cisplatin, fluorouracil, and radiotherapy reduces the local failure rate by ≥ 50% at 3 years (compared with historical data) in immunocompetent patients with stage I-III invasive anal carcinoma.
Secondary Objectives:
- Determine objective response rate (complete and partial), progression-free survival, colostomy-free survival, and overall survival.
- Determine the overall toxicity of concurrent cisplatin, fluorouracil, and radiation therapy combined with cetuximab.

结局指标
主要结局
Local Failure Rate at 3 Years
时间窗: assessed every 3 months for patients within 2 years of registration, then every 6 months for patients in year 3
Local failure was defined as progression/relapse of disease in the anal canal and/or regional organs and/or regional lymph nodes after completion of protocol therapy, or progression during protocol therapy. Lost to follow-up and death (regardless of cause of death) prior to 3 years were also considered as local failures. For the calculation of local failure rate at 3 years, patients were classified into two groups (ie, coded as binary variable): failure (patients with local failure events prior to 3 years) vs. no failure (patients who still alive and had no local failure at 3 years). The binomial proportion and its exact two-sided 80% confidence interval (CI) were used to estimate it.
次要结局
- Objective Response Rate(Tumor assessments were made at baseline, within 4 weeks of the completion of protocol treatment, then every 6 months if patient was 1-4 years from registration, yearly if patient was 5-10 years from registration until progression/relapse using the RECIST)
- 3-year Progression-free Survival Rate(assessed every 3 months for patients within 2 years of registration, then every 6 months for patients in year 3)
- 3-year Overall Survival Rate(assessed every 3 months for patients within 2 years of registration, then every 6 months for patients in year 3)
- 3-year Colostomy-free Survival Rate(assessed every 3 months for patients within 2 years of registration, then every 6 months for patients in year 3)
