Liu Z, et al. – Researchers evaluated Chinese individuals living in various regions worldwide to study the differences in cancer profiles. In all, they identified significant differences in cancer incidence by sex, period, and age across regions. The most notable variations were determined among those from Shanghai and American Chinese individuals in Los Angeles. For cancer site, the most significant differences were detected in prostate, gastrointestinal, gynecologic, oral cavity and pharynx, and brain and central nervous system (CNS) cancers. Shanghai was significantly higher in stomach, liver, esophageal, pancreatic, and brain and CNS cancers, while lower in colon, prostate, breast, cervical, and oral cavity and pharynx cancers.
