Two primary cancers mean that a patient has organizationally different kinds of primary malignant tumors simultaneously or serially. Synchronous double primary cancers are defined as the case of the second cancer is found within 6 months after the diagnosis of the first cancer. And, when the interval is more than 6 months, it is called metachronous two primary cancers. From January 1996 to December 2007, 39 patients who were diagnosed as two primary cancers in the stomach and the liver at Dongsan Medical Center, Keimyung University, were reviewed retrospectively. The survival time was 16.1 ± 14.8 months in synchronous double primary cancers, and 51.9 ± 31.0 months in metachronous double primary cancers. At the time of dignosis, the cancer stage was earlier in metachronous cancers than synchronous cancers. In conclusion, regular follow-up examination should be needed in order to earlier diagnosis of sencond primary cancer.
