RESUMO
A case of gastric endocrine cell carcinoma successfully treated by FU (5-FU/UFT) +irinotecan (CPT-11) adjuvant therapy against recurrent metastases is reported with some discussion. A 69-year-old man was admitted to our hospital with severe anemia. He was diagnosed with advanced gastric cancer, T3N1H0P0M0, Stage IIIa. Total gastrectomy with pancreato-splenectomy with D2 lymph node dissection was done for curative resection. The pathological diagnosis was gastric endocrine cell carcinoma because Grimelius and Chromogranin A stained positive histologically. Seven months after operation, recurrent liver metastases with tumor embolism of the portal vein were revealed by enhanced CT examination. FU (5-FU/UFT) +CPT-11 was done as the first-line adjuvant chemotherapy. Metastatic lesion of the liver and portal vein tumor embolism was decreased. Tumor marker CA19-9 level was also decreased and within normal limits. This therapy was evaluated as a partial response (PR) in twelve months and the patient died three years and eight months after operation. Gastric endocrine cell carcinoma is known as a potentially highly malignant tumor. But in our case FU+CPT-11 controlled growth of the recurrent tumor. Based on this finding, we recommend adjuvant chemotherapy by FU+CPT-11 for gastric endocrine cell carcinoma.

A resected case of squamous cell carcinoma associated with ductal carcinoma in the hemilateral breast successfully treated by FU plus cisplatin (CDDP) adjuvant therapy against recurrent metastases is reported with some discussion. A 42-year-old woman was admitted to our hospital because of right breast tumor. By physical examination, mammography, ultrasound examination and aspirated cytology, we diagnosed squamous cell carcinoma of the right breast. Before operation SCC antigen was elevated. Standard mastectomy was performed, and SCC antigen was decreased within normal range. Then, a standard regimen of chemotherapy using docetaxel with anti-hormonal therapy by LH-RH analog and tamoxifen was done as first-line adjuvant therapy. Four months after operation the SCC antigen level was elevated again, and recurrence of cancer (skin and liver metastases) was recognized. Next, we tried 5-FU/UFT plus CDDP for squamous cell carcinoma of other organs such as the esophagus. These anti-tumor drugs proved effective, and no metastasis of the skin was detected thereafter, and liver metastatic lesion was decreased in ten months. The SCC antigen level was within the normal range again. Additionally, when metastases redeveloped, TS-1 plus CDDP controlled growth of tumors in seven months. Based on the present findings,we recommend adjuvant chemotherapy by FU plus CDDP for squamous cell carcinoma of the breast.
