Among 500 cases of surgically resected lung cancer in a recent 22-year period from January 1973 to January 1994, there were 29 cases (6%) of multiple primary cancer including 25 cases of double cancer and 2 cases of triple cancer and each 1 case of quartuple and quintuple cancer. Four cases had synchronous and 25 cases had metachronous multiple cancer. The patient's age at the time of the lung resection ranged from 47 to 80 years old (average: 65.8).
The most commn site of the other primary cancers was the head and neck (9 cases), followed by the stomach (6 cases), thyroid (4), colon (3), mamma (2) and liver (2). Nineteen of 29 patients had already died. Ten of them died of lung cancer and the remaining nine of other cancer or MOF. There are five long survivors over 5 years. Therefore, basic diagnostic and therapeutic policies for newly appearing lesions in the lung or other organs should be formalised.
It is considered that such surgical cases might increase henceforth.
