Abstract   Purpose: Adenosquamous carcinoma, a rare malignant tumor of the stomach, is char- acterized by two different cell components, one adenomatous and the other squamous component. Its clinicopathologic feature and prognosis are quite different from the ordinary adenocarcinomas. We report our experience of 9 such cases. Materials and Methods: Clinical and pathologic features were reviewed for the 9 patients who undenwent gastrectomies and were confirmed as adenosquamous carcinoma by pathologists during the 10-year period of from 1987 to 1998. Postoperative adjuvant therapy and prognosis were also reviewed. Results: The ages of 6 male and 3 female patients ranged from 30 to 59, with the median age of 48. Total gastrectomy was done in 4 cases, while other underwent subtotal gastrectomy. Curative resection was done in four cases. Fourteeen additional organs were resected concomitantly due to suspicious tumor invasion and among them 9 organs were histologically confirmed for tumor invasion. The mean tumor size was 7.4 cm (2.5-27 cm) and all cases were pathologically advanced. One case showed peritoneal seeding and 3 cases showed hepatic metastases. There were 7 cases of stage IV disease by the UICC TNM classification (5th ed.) and the other two were stage II and stage IIlb respectively. Eight cases received postoperative adjuvant chemotherapy comprising S-FU, DDP, adria- mycin, picibanil or VP-16. Of 9 patients, 6 died and the overall 5-year survival rate was 15.3%. Conclusion: Adenosquamous cancer of stomach is regarded as a disease of unfavorable prognosis, which was confirmed by this study. The treatments were not quite different from those for other stomach cancers. Although more cases and further investigations are essential for complete understanding of the clinical prognosis and proper treatment of the gastric adenosquamous cancer, early diagnosis, curative resection and close postoperative follow-ups are currently available options for better outcome of this disease.
