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.
