[Incidence of multiple cancer]
식도암과 연관된 다른 장기의 암에 대한 Keio 대학의 자료입니다 (Okamoto. Ann Thorac Surg 2004). 일부는 antecedent, 일부는 synchronous, 일부는 metachronous입니다. Synchronous가 무려 49%라는 점이 놀랍습니다. 무척 일본적인 자료이고 우리나라와는 사뭇 다릅니다. 일본의 위암과 우리나라의 위암이 얼마나 다른지 어렴풋이 느껴집니다. 여하튼 흥미롭습니다. Gastric tube cancer는 7%였습니다.
흥미로운 점은 비교적 좋은 치료결과입니다 (Okamoto. Ann Thorac Surg 2004). 7명 중 5명의 치료결과가 성공적이었다고 보고하였습니다. 요약의 일부를 옮깁니다.
"Gastric cancer was detected during follow-up endoscopic examinations or in an upper gastrointestinal series in seven patients. All of the cancers were diagnosed as adenocarcinoma histopathologically. Endoscopic mucosal resection was performed in two patients, partial resection of the residual stomach was performed in three patients. One patient was treated by endoscopic mucosal resection as palliative therapy, since he had severe pulmonary emphysema. Total resection of the gastric tube was attempted in 2 advanced cases but was unsuccessful because of direct invasion of other organ by the cancer. The 5 patients who underwent curative resection are alive with no subsequent recurrence."
