title: [A case of advanced colon cancer resected successfully after neoadjuvant chemotherapy].
abstract: This case concerns a 54-year-old male patient who had been identified as having a type 2 tumor in the cecum, which subsequent pathologic examination revealed to be an adenocarcinoma. The results of a computed tomography (CT) scan suggested that the tumor had directly invaded the right iliopsoas. Neoadjuvant chemotherapy was performed to avoid a non-curative resection. CT and positron-emission tomography(PET) findings after the 6th course of chemotherapy revealed a significant reduction in tumor size, at which point a right hemicolectomy with D3 nodal dissection was performed. The changes from neoadjuvant chemotherapy were judged to be Grade 1a. The patient was recurrence-free at his 14- months follow-up examination. Neoadjuvant chemotherapy with a drug that targets a specific molecule is a useful treatment for patients with an unresectable primary cancer.
