Abstract
Recently, multiple cancers tend to be increasing as cancer patient on average have been living longer due to the development of diagnosis for cancers, and multidisciplinary treatment for cancers.
We present a 59-year-old male with four primary cancers, which appeared in stomach, sigmoid colon, oral floor, and parotis respectively. The patient was admitted to our department because of oral floor pain in May, 1987. He was diagnosed as carcinoma of oral floor, and recieved radiation, surgery and chemotherapy. Parotid carcinoma appeared, however, 4 months after discharge from our hospital. He died of extention of the tumor in spite of the treatment at department of otorhinolaryngology of our hospital. He also received treatments of cancers, in stomach in 1980 and sigmoid colon in 1982 at another hospital.
