Abstract

BACKGROUND/AIMS:

We investigated the outcomes of patients with early gastric cancer, with special reference to the prognosis of patients with synchronous or metachronous primary malignancies in organs other than the stomach.

PATIENTS AND METHODS:

Among 890 patients with early gastric cancer, 97 (10.9%) had synchronous or metachronous primary malignancies in organs other than the stomach. Ten-year survival rates were compared between patients who had additional malignancies and patients who had early gastric cancer but no other malignant disease (control group).

RESULTS:

Synchronous primary malignancies were detected in 32 patients and metachronous primary malignancies were detected in 65 patients (17 had developed before gastrectomy and 48 developed after gastrectomy). Hepatic cell carcinoma, lung cancer and colorectal cancer were frequently detected between 2 and 24 years after gastrectomy. The 10-year survival rate was 80.8% for 769 patients in the control group but it was only 49.7% for the 92 patients with additional malignancies. Moreover, metachronous malignant disease was found more over 10 years after gastrectomy in 30 of the 48 cases (62.5%).

CONCLUSIONS:

These results suggest the importance of long-term follow-up for detection of metachronous carcinomas at sites other than the stomach for patients with early gastric cancer.
