We reported a case of super-elderly
colon cancer with peritoneal dissemination effectively treated with modified FOLFOX6
chemotherapy. A 80-year-old woman was referred to our hospital for abdominal distension in January 2007. Abdominal CT showed peritoneal dissemination and colonoscopy revealed transverse colon
cancer. The patient's performance status (PS) score was 3. She had
pleural effusion on the left side and massive acsites. After the general condition was improved, operation was performed for sub-
ileus in March, but it became a probe
laparotomy for severe peritoneal dissemination. We tried modified FOLFOX6
chemotherapy from April. The patient's
pleural effusion decreased after 3 courses of
chemotherapy and we could remove the thoracic tube. Massive acsites observed in abdominal CT disappeared after 5 courses of
chemotherapy. The patient did not suffer from sub-
ileus after around 8 courses of
chemotherapy and she could then take food. The patient's PS score became 1, and she was discharged in September. Two more courses of
chemotherapy were given on as an outpatient basis. The
chemotherapy was changed to S-1 on the patient's request in November. As of February 2008, the patient's PS score was 0, and she has been under treatment as an outpatient.
