Personalized treatment of rectal cancer with induction chemotherapy, radiation therapy and consolidation chemotherapy

Basic Information

Recruitment status Recruiting
Health condition(s) or Problem(s) studiedRectal cancer
Date of first enrollment11/05/2022
Target sample size40
Countries of recruitment
Study typeInterventional
Intervention(s)Induction and consolidation chemotherapy: Oxaliplatin 130mg/sqm over 2 hours, day1. Capecitaine according to the body surface area (refer to the following) twice daily days1-15 every 3 weeks. Repeat 3 cycles. Single dose <1.36sqm, 1200mg. 1.36sqm=< and 1.66sqm>, 1500mg. 1.66sqm=< and 1.96sqm>, 1800mg. >1.96sqm, 2100mg. Radiotherapy: 25Gy in 5 fractions to the pelvis. Surgery: Surgery is performed as soon as possible (after recovery from adverse effects of chemotherapy) if the patient is judged effective within 4 weeks after the last dose of induction chemotherapy and is found to be negative for lateral lymph nodes, negative for CRM and EMVI, and cT3. Surgery is either sphincter function-preserving (low anterior resection, intersphincteric resection) or non-sphincter function-preserving (Hartmann's operation, abdominoperineal resection), but the details of the procedure are determined based on patient factors. For patients with lateral lymph node metastasis, lateral lymph node dissection of the side with lymph node metastasis before treatment should be performed. In cases of stenosis, induction chemotherapy should be given after loop stoma construction. The choice of approach (open, laparoscopic, or robot) and diverting stoma construction is left to each institution. Postoperative therapy: In the case of induction chemotherapy alone, 5 courses of capecitabine are administered as postoperative adjuvant chemotherapy. In the case of induction chemotherapy, radiation therapy and consolidation chemotherapy, no postoperative treatment is given.


Primary Outcome3-year disease-free survival rate
Secondary OutcomeOverall survival, pCR rate, R0 rate, local recurrence rate, completion rate of preoperative treatment, incidence rate of adverse events, and incidence rate of surgical complications
