Situation of radiotherapy in Latin America.

A survey to evaluate situation of radiotherapy in Latin America was conducted. Consultation was made with representatives of 10 countries, resulting in the responses of 5. These five countries represent around 80% and 81%, respectively, from the total area and population of South America. Situation of equipment, modern facilities, and human resources is analyzed. A Cobalt machine is the basic megavoltage equipment in Latin America; half of the total number, however, is of old units with very low output sources. Linacs represent one-third of cobalt machines, the majority of low photon energy without electron capability. Treatment planning, localization, patient positioning, and immobilization are inadequade or of low quality in a high number of institutions. Teaching programs are insufficient or inexistent in certain areas. Late diagnosis and referral for treatment is a major problem for cancer control in Latin America. Hierarchization and regionalization of radiation therapy centers are indicated as a way to provide high quality services and teaching programs. In Latin America, lodging and facilities for transportation are essential to assure the continuity of radiation treatment and regular follow-up to patients from rural or distant areas.
