简要总结
RATIONALE: Drugs used in chemotherapy, such as fluorouracil and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as panitumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether chemotherapy is more effective with or without panitumumab in treating patients with colon cancer.
PURPOSE: This randomized phase III trial assessing whether preoperative chemotherapy and/or an anti-EGFR monoclonal antibody improve outcome in high risk operable colon cancer.
详细描述
FOxTROT is a multi-centre randomised controlled trial (RCT) with the following objectives:
Primary objectives:
- To determine if neoadjuvant chemotherapy with or without panitumumab followed by deferred surgery and completion of chemotherapy postoperatively can reduce the 2-year recurrence as compared to surgery and postoperative chemotherapy with or without panitumumab.
- To determine if, in patients with RAS-wt tumours, adding panitumumab to neoadjuvant therapy increases anti-tumour activity as measured by tumour shrinkage.
Secondary
- To assess the accuracy of pre-treatment CT scan staging.
- To assess the tolerability of the neoadjuvant therapies.
- To assess the nature and frequency of surgical complications.
- To measure the impact of the treatments on quality of life and on resource usage.
- To assess whether adding panitumumab to neoadjuvant CT reduces 2-year recurrence
- To assess the prognostic and predictive value of tumour biomarkers
- To assess the influence of resectional quality on outcome
