[A case of a pulmonary large cell carcinoma patient who has still been surviving for four years even with triple carcinoma developed on different occasions (rectum, stomach: resected; lung: nonresected)].

: The case occurs on an 86-year-old man. In May 1977, Miles' operation was performed for rectal cancer (papillary tubular adenocarcinoma), together with additional proctostomy. In March 1984, subtotal gastrectomy was performed for an early stomach cancer (moderately-differentiated tubular adenocarcinoma). In September 1985, chemotherapy with 3 courses of CDDP (50 mg x 1) plus VDS (3 mg x 3) and liniac irradiation (60 Gy in total) were performed for pulmonary large cell carcinoma. Restiform shadows and fibrosed foci were left behind, but thereafter only the former was persisted without anticancer therapy. Now in December 1989, he has still been surviving without any sign of local recurrence of remote metastasis. Neither anticancer therapy was tried for the first and second cancers nor a cancer family history was found about him.
