Treatments for second malignancies after gastrectomy for stomach cancer.
OBJECTIVE
Metachronous primary cancers after stomach cancer were reported as a cause of late death. It is necessary to treat these second malignancies to improve the result of surgical treatment for gastric cancer.


METHODS
Among 3,570 patients who underwent gastrectomy during 1961-1986, 160 second primary malignancies were observed as of December of 1991. Liver (27 patients) and colorectal (18 patients) cancers were the largest in number.


RESULTS
By the end of 1992, for 32 liver tumors small resection, transcatheter arterial embolization and percutaneous ethanol injection were carried out and 3-year survival of resected cases (6 patients; 80.0%) was better than that of nonresected cases (26; 3.8%) (p < 0.05). In 19 colorectal cancers, surgical resection (13/19) and combined locoregional chemotherapy (2/19) were actively performed, and 5-year survival of resected cases (13; 55.4%) was better than that of nonresected cases (6; 0%) (p < 0.05).


CONCLUSIONS
With an intensive long-term follow-up after gastrectomy for cancer, early diagnosis and effective therapy for second primary malignancies is improved.
