RESUMO
Here we report a rare case with perforation of gastric cancer responding to chemotherapy. The patient was a 74- year-old male who underwent abdominal ultrasonography and contrast CT because of body-weight lost and poor appetite in June, 2004 and whose lymph node(LN)swelling was seen in the level from the hepatic to the renal hilum. A gastric wall irregularity was also seen. We suspected gastric cancer with LN metastasis and carried out upper gastrointestinal endoscopy. Then it demonstrated type 2 advanced gastric cancer from the upper to the middle body. The pathological diagnosis of gastric tumor was poorly-differentiated adenocarcinoma containing por 2, tub 1, and pap. The patient was treated with S-1, CDDP and CPT-11 and remained ambulant. After completion of 1 course of chemotherapy, he complained of intense abdominal pain, so we carried out upper gastrointestinal endoscopy and found perforation in the stomach at the same location as the gastric cancer. Emergency total gastrectomy was performed at once. The histopathological finding showed disappearance of the cancer cell not only in the stomach but also accessory LN. Because the remnant LN metastasis was seen in the hepatic hilum at abdominal contrast CT after operation, S-1 was administered to the patient as 60 mg/m2/day in ambulant. Now, over 40 months after the operation, the patient has been alive with good performance status and disappearance of LN metastasis.
