title: Photodynamic therapy: Progress toward a scientific and clinical network in Latin America.
abstract: Cancer is one of the major challenges for Latin America health services, since the skin cancer is the most frequent lesion. This manuscript addresses an initiative for the treatment of basal cell carcinomas (BCC) by photodynamic therapy (PDT) based on a government-funded national program in Brazil. The program provides clinical training and facilitates access to drugs/equipment and significantly reduces PDT costs. It also lays foundations for the establishment of a Latin American research network to improve prevention, early detection and treatment of diseases. Centers have been established by direct contact (conferences, visits to healthcare facilities and official departments). A local training was divided into complementary theoretical and practical parts. This is an ongoing project that has involved 10 countries: Brazil, Bolivia Chile, Ecuador, El Salvador, Colombia, Cuba, Mexico, Peru and Venezuela, The initial results are encouraging and have provided assessment of Latin America patients relating, for example, the most common skin phototypes with incidence of BCC in such countries. The network is expected to produce relevant scientific information for PDT introduction in many countries. The experience acquired by local teams shall enable them to innovate PDT protocols and increase the number of skilled contributors/researchers to broaden knowledge on the ever-crescent PDT field in Latin America. The establishment of a collaboration network and introduction of other projects and experience exchange shall become an easier process with time. This PDT clinical research network is a start for the strengthening of Science in South Hemisphere countries.
