- Scientific TitleA Multicenter Phase III Randomised Trial comparing Total Mesorectal Excision with Pre-operative Radiotherapy with or without Post-operative Oral Capecitabine in the Treatment of Operable Primary Rectal Cancer.
- ACRONYMSCRIPT
- hypothesisThe overall survival in the arm treated without chemotherapy (TNM-stage II or III tumours) is expected to be approximately 60%. Assuming an improvement in overall survival from 60% to 70% in the arm treated with chemotherapy (TNM-stage II or III tumours), 840 patients are needed; 420 in each arm (alpha 0.05, two sided; power 0.90).

- Brief summaryBackground:
Of major concern in the treatment of rectal cancer is the development of local and distant recurrences. Local recurrence rates have been reduced by both TME-surgery and pre-operative hypofractioned radiotherapy. So far, chemotherapy has shown little or no effect in combination with conventional surgery in the prevention of distant recurrences and improvement of survival. This may in part be explained by the high rate of local recurrence, which might have masked the beneficial effect of chemotherapy. The role of adjuvant chemotherapy has never been tested in combination with standardised TME-surgery. In the CKVO 95-04 trial, the beneficial role of pre-operative, short-term radiotherapy has been confirmed in combination with standardised and quality-controlled TME-surgery and pathology. In this successor trial, the additional value of post-operative chemotherapy will be evaluated in the same setting.

Study objectives:
Main objective: To investigate in a randomised fashion whether chemotherapy after standardised TME-surgery with pre-operative radiotherapy, leads to a substantial improvement in overall survival. Secondary objective: To investigate in a randomised fashion whether post-operative chemotherapy leads to a substantial improvement in local and distant tumour control, when standardised TME-surgery with pre-operative radiotherapy and pathology are applied.

Selection criteria:
The issue of this trial will be studied through randomisation for yes/no post-operative chemotherapy; only patients with a TNM-stage II or III rectal adenocarcinoma without any macroscopical residual tumour are eligible for this randomisation. The lower margin of the tumour must have been located within 15 cm of the anal verge. TME-surgery must have been performed and all patients must have received preoperative radiotherapy with 5x5 Gy. Only patients with WHO performance status 2 or less and without contraindications to chemotherapy are eligible.

Study design:
Pathological examination of the resected specimen must have been done according to the protocol of Quirke. If a patient is randomised for chemotherapy, 8 courses of capecitabine are given. Primary end-point will be overall survival and secondary endpoints will be overall recurrence rate (local + distant recurrence) and local and distant recurrence separately. All randomised patients will be followed for the end-points.

Statistical considerations:
The overall survival in the arm treated without chemotherapy (TNM-stage II or III tumours) is expected to be approximately 60%. Assuming an improvement in overall survival from 60% to 70% in the arm treated with chemotherapy (TNM-stage II or III tumours), 840 patients are needed; 420 in each arm (alpha 0.05, two sided; power 0.90).
