N/A Background: There have been many reports about the multiple primary cancers, and they have played a role to study the pathogenesis of the cancer. Methods: During 25 years from 1967 until 1991, 22946 primary cancers had registered at the Presbyterian Medical Canter, and there were 68 cases of multiple primary cancers compatible with Warren k Gates' criteria. Among them 29 cases were multiple primary cancers associated with gastric cancer. Results: The incidence of multiple primary cancers associated with gasric cancer is 0.13% in total primary cancers (0. 38% in total stomach cancers, 42,6% in total multiple primary cancers). All stomach cancers were adenocarcinomas. The other sites except for stomach are esophagus (8; all squamous cell carcinomas), liver (4; all hepatocellular carcinomas), uterine cervix (4; all squamous cell carcinomas), larynx (3; all squamous cell carcinomas) and miscellaneous (10). The ratio between synchronous and metachronous (interval more than 6 months) is 1.07:1, and the average time interval between first and second cancer in the metachronous cases is 5, 7 years. The 9 cases of 14 metachronous cases were treated with chemotherpy of radiation therapy after first surgery. Conclusion: The multiple primary cancers associated with gastric cancer may be largely caused by exposure to the same carcinogens in the contiguous aerodigestive organs and also iatrogenic causes play an important role in the pathogenesis of the multiple primary cancers.

The present study was carried out to evaluate the effect of avian pox on wild bird population by investigating the avian pox infection in migratory birds of a stopover site. 3,565 birds in 116 species were examined for avian pox in migratory birds at the Heuksando island in South Korea during the spring and fall of 2011. 20 birds in 12 species were found pox-like lesions and 5 birds were diagnosed by avian pox using PCR: Pale Thrush (Turdus pallidus), Yellow-breasted Bunting (Emberiza aureola), Yellow-throated Bunting (Emberiza elegans), Rustic Bunting (Emberiza rustica), Black-faced Bunting (Emberiza spodocephala). To our knowledge, this is the first report of avian pox detected in these 5 species of the world.
