[The chemotherapy with mFOLFOX6 for advanced colon cancer was effective for gastric cancer - a case report].

The patient was a 72-year-old woman, admitted to our hospital due to appetite loss. We performed gastroscopy, colonoscopy and abdominal CT. She had both advanced ascending colon cancer with multiple liver metastasis(cStage IV: cT3N1H3)and early gastric cancer(cStage 0: cTisN0M0). She received chemotherapy with modified FOLFOX6(mFOLFOX6), and the chemotherapy was judged effective for her gastric cancer. During the next 6 months, a total of 10 courses had been performed. The tumor marker scores(CEA, CA19-9)decreased significantly. Gastric cancer was diagnosed as CR(complete response)in gastroscopy after 6 courses of chemotherapy. In this case, chemotherapy with mFOLFOX6 was effective for gastric cancer.
