 To determine the efficacy of HIPEC in the treatment of locally advanced colorectal cancer, patients are randomized into HIPEC group and control group. In HIPEC group, the patients undergo radical colorectal resection with lymphadenectomy and HIPEC with paclitaxel and 5-Fu. Patients in the control group just undergo radical colorectal resection with lymphadenectomy. Patients in both groups receive 8 cycles of postoperative chemotherapy XELOX and are followed up for 5 years or until death.
