En 1983, durante la creación de un nuevo método para medir la secreción gástrica sin intubación, sorprendió la dificultad para encontrar pacientes peruanos dispépticos con hiperclorhidria. A Un el encontrar niveles altos dentro de lo que se considera acidez gástrica normal era difícil. La gran mayoría de pacientes tenía hipoclorhidria o, a lo más, niveles normales bajos de acidez. El nuevo método fue presentado en un reunión científica en 1985(1),y publicado formalmente en 1987 (2), pero ya desde 1983 quedó la sospecha deuna alta prevalencia de gastritis crónica atrófica en pacientes dispépticos peruanos como causa de la tendencia a hipoclorhidria.

Purpose: Latin America faces a shortage in radiation therapy (RT) units and qualified personnel for timely and high-quality treatment of patients with cancer. Investing in equitable and inclusive access to RT over the next decade would prevent thousands of deaths. Measuring the investment gap and payoff is necessary for stakeholder discussions and capacity planning efforts. Methods and Materials: Data were collected from the International Atomic Energy Agency's Directory of Radiotherapy Centers, industry stakeholders, and individual surveys sent to national scientific societies. Nationwide data on available devices and personnel were compiled. The 10 most common cancers in 2020 with RT indication and their respective incidence rates were considered for gap calculations. The gross 2-year financial return on investment was calculated based on an average monthly salary across Latin America....
