In our clinic we have treated 688 cases of malignant tumors from 1966 to 1980. Of these 29 (4.3%) were multiple primary malignant tumors, i. e, one case of quadruple, 3 triple and 25 double malignant tumors.We reported a case of a quadruple primary malignant tumor in detail, together with a statistical analysis of our 29 multiple primary malignant tumors.In our series, 20 were males and 9 were females, but the frequency of multiple primary malignant tumors between males and females were almost equal. The average age of 25 double malignant tumors was 63.6 years old; and the average interval between the first tumor and the second tumor was 5.06 years and 36% were synchronous (within one year) and 64% were nonsynchronous.The combination of laryngeal cancer and stomach cancer occurred in 7 (24.1%) and was seen most frequently.
