5. Study Description
Brief Summary
The use of preoperative chemoradiation and adjuvant chemotherapy with 5-FU based chemotherapy reduced local recurrence rate to less than 10%, but has only had limited effect on overall survival due to the constantly high (more than 30%) rate of distant metastasis.
However, it has been shown that complete eradication of the primary tumour observed in the histopathological specimen (pathological complete response, pCR) correlates with a favourable overall prognosis so obtaining a pCR might be beneficial. The aim of the study is to investigate whether the addition of bevacizumab to preoperative fluoropyrimidinebased chemoradiation improves pathological complete remission rate in locally advanced rectal cancer with acceptable toxicity. Secondary objectives are to evaluate pathological downstaging rate, histopathological R0 resection rate,sphincter preservation rate, perioperative surgical complication rate, local control, DFS, OS, late toxicity and quality of life.
Detailed Description
radiotherapy: 45 Gy to the pelvis (25x 1.8 Gy on days 1-33, excluding weekends) plus 5.4 Gy on days 36-38 as a boost to the primary tumour (3 fractions of 1.8 Gy).Three- dimensional CT planing and a four field box technique with high energy photons (15 MV) will be used. All fields will be treated daily. Multileaf collimators will be used to shape individual radiation fields. Patients will be irradiated in a prone position with a full bladder and by using belly board to minimize exposure of the small bowel.
capecitabine 825 mg/m² p.o. twice daily on days 1-38 (including weekends),
bevacizumab: at dose 5 mg/kg on days -14, 2, 16,30.
Radical surgery (TME): to be undertaken ideally 6-8 weeks following completion of chemoradiation.
Postoperative treatment (in patients achieving histopathological R0 or R1 resection):capecitabine 1250 mg/m² p.o. twice daily for 14 consecutive days every three weeks; 4 cycles (R0)or 6 cycles (R1) beginning 6-8 weeks after surgery
