Aim: Despite significant advances in cancer genetics research in Latin America, the access to routine medical care for hereditary cancer patients is still limited.

Aim: To assess clinical resources for Lynch syndrome (LS) management across Latin American countries.

Method: International survey including selection criteria, clinical and genetic information was sent out to the 26 recently described LS programs from 10/33 countries of Latin America (Vaccaro et al. submitted).

Results: Amsterdam or Bethesda guidelines were mostly used to select patients for a tumor screening test and/or genetic MMR sequencing in 15/26 LS programs from public (n=7) or private (n=8) hospitals located in large urban areas from Argentina, Brazil, Chile, Colombia, Mexico, Peru and Uruguay. 717 LS carriers have been identified with a mean age of 42.5 years (range 32-50.9) and a mean of 3.7 follow-up years (range 1-9.6).

Conclusion: Several research projects and publications have been implemented, generating knowledge of MMR variants in these populations to bring additional awareness to medical professionals and public health leaders. Participation in PLSD and international collaborations have been initiated to support the implementation of genetic testing and research in most of the countries of Latin America.
