[Long-term survival of a case of rectal cancer discovered after resection of a single brain metastasis].

: A woman in her fifties had shown a decline of orientation before admission. She had a tumor in the left frontal lobe. The solitary tumor was resected. Rectal cancer was discovered after that, and she underwent the Hartmann procedure. The final diagnosis was metastatic brain carcinoma from primary rectal cancer. Subsequently recurrence of brain metastasis was diagnosed, and gamma knife radiosurgery was performed. She then received adjuvant chemotherapy for about 1 year. Since the gamma knife treatment, she has been followed up without any further evidence of recurrence. We believe that if solitary brain metastases are found early adjuvant therapy should be performed, which should prolong survival.
