Metrics details. The situation of patients developing multiple primary cancers is becoming more frequent and graver. This study investigated the risks of developing second primary cancers that are related to first primary cancers, and the interval times of synchronous and metachronous multiple primary cancers. A two-month period between first- and second- primary cancers was used to differentiate metachronous and synchronous multiple primary cancers. The combinations of subsequent cancers and relative risks RRs of having multiple primary cancers versus having single primary cancer for the top-ten first and second primary cancers were examined. The RR was adjusted for age of the first primary cancer. A survival analysis of the time to second-primary-cancer development was performed. Multiple primary cancers were found in 1. Most After adjustment for age at first diagnosis, head and neck cancers had the highest metachronous association with second esophageal cancers RR, Prostate cancer and second colorectal cancer also demonstrated a high metachronous association RR, 2.

Cancer statistics, metachronous, Therefore, SV40 is potentially associated with cancer formation.

The term metachronous is used in oncology to refer to two or more independent primary malignancies, when the second or third, etc. These may be in the same, or in different, organs.

Second cancers developed within 2 years for first lung cancers and for head and neck cancers. They should be distinctly separate by at least 4 cm distance and they should not consist of submucosal spread or a satellite lesion of each other. The primary cancer site was defined as per the ICD-O-3 description [ 12 ], and it was categorized into 20 major types of solid cancer, based on topography codes. In accordance with our series, several studies showed no significant difference in survival between multiple and single colorectal cancers 4 , 6.
