[A case of cerebellum metastasis from colon cancer]

We report a case of cerebellum metastasis from transverse colon cancer, which had no evidence of recurrence in the thoracoabdominal region by chemotherapy and resection of liver and lung metastases after initial operation. The case is a 71-year-old male. We performed a radical resection of transverse colon cancer (D2) in 2001. The finding was moderately-differentiated adenocarcinoma, se, n1, ly1, v2, H0, P0, M0, stage IIIa. Relapsing tumor, which metastasized to the liver in 3 years, the right lung in 4 years and 8 months and the left lung in 5 years and 11 months after initial operation, were totally resected. Following the partial resection of the left lung, he received a treatment with 12 times of mFOLFOX6 and S-1+PSK. There was a good control observed in the thoracoabdominal region with no metastases for 14 months. However, drift and dizziness developed in April 2008, and cerebellum metastasis was diagnosed by MRI. He underwent a partial resection of cerebellum tumor, radiation therapy and FOLFIRI. He has been alive for 1 year after the treatment of the cerebellum metastasis, and there has been no evidence of recurrence in the thoracoabdominal region in 8 years after initial operation.
