RESUMO
We report two cases of early gastric cancer with distant metastases (stage IV). At our institute 1428 cases of primary gastric cancer were resected between 1980 and 1997; 536 were diagnosed as early gastric cancer based on the resected specimens (304 cases of mucosal cancer, Tis--TNM classification--and 232 of submucosal cancer, T1). 528 of these 536 cases were classified as histological stage I, six as stage II, none as stage III and two as stage IV. The incidence of stage IV early gastric cancer was 0.14% of all gastric cancers and 0.37% of the early gastric cancers. The two patients with stage IV early gastric cancer were women. Both tumors were defined as early cancer because they were confined to the submucosa. One was a type 0 IIc + III early cancer, histologically classifiable as a small, moderately differentiated adenocarcinoma (tub2 according to the Japanese Classification of Gastric Carcinoma, G2; TNM classification: ICD-O C16), size 10 x 8 mm; the other was a surface spreading type 0 IIc, classifiable as a signet-ring cell carcinoma (sig, G3), size 50 x 35 mm. Stage IV factors were N3 in the first and ovarian metastasis (Krukenberg tumor) in the second case.
