Abstract
A 60-year-old man underwent sigmoid loop colostomy for obstructive rectal cancer. Computed tomography (CT) showed a circumferential thickening of the lower rectal wall caused by a tumor invading the posterior and side pelvic wall. As we considered R0 resection too difficult, we gave the patient bevacizumab plus FOLFOX4 (oxaliplatin, leucovorin, and 5-fluorouracil). After eight courses, CT showed improvement in the rectal wall thickening but linear thickening of the mesorectal fascia remained. We therefore gave the patient chemoradiotherapy (CRT), and then 10 weeks later performed Hartmann’s operation laparoscopically. Microscopic examination revealed that the tumor had been almost replaced by fibrous tissue, with only a few cancer cells left in the subserosa. The circumferential resection margin was free of cancer cells. The patient is doing well after 27 months of follow-up. This case suggests that systemic chemotherapy with FOLFOX4 plus bevacizumab prior to conventional preoperative CRT is a promising strategy for patients with initially unresectable locally advanced rectal cancer.
