[A case of nonresected gastric cancer with peritoneal dissemination effectively treated by S-1/DOC and PTX/ CDDP combination chemotherapy with good QOL]

Abstract

We performed combination chemotherapy in the outpatient clinic on a 47-year-old man with nonresected gastric cancer accompanied by peritoneal dissemination. At first we administered S-1/DOC combination chemotherapy. Afterwards a rise of tumor marker (CEA) occurred accompanying taste disorder and edema of the lower limbs, so we changed to combination chemotherapy for PTX/CDDP. Since the only side effect was numbness, the patient was treated on an outpatient basis while working. The case achieved good QOL by these combination chemotherapy methods for 1 year 10 months post exploratory laparotomy.
