OBJETIVOS: determinar si existe informacion cientifica publicada que permita validar el uso de A. muricata para tratar el cancer en pacientes. METODOS: se realizo una revision en las principales bases de datos de bibliografia cientifica biomedica disponibles (BVS-BIREME /11/, COCHRANE /0/, PubMed /5/, LILACS /2/, SciELO /0/, SeCiMed /0/, EBSCO /2/) con las palabras claves Anonna AND muricata AND cancer, asi como en Google con la estrategia: graviola AND cancer. La informacion fue analizada para determinar si podia sustentar la recomendacion antes senalada. RESULTADOS: encontramos que los estudios cientificos publicados que pudieran sustentar la recomendacion de esta planta o alguno de sus extractos son en modelos experimentales in vitro y la mayoria con principios activos puros extraidos. CONCLUSIONES: no existe suficiente evidencia para recomendar el uso de ningun extracto o principio activo de A muricata y la divulgacion infundada de sus extraordinarias propiedades anticancerigenas es eticamente inaceptable(AU) INTRODUCTION: the dissemination of information about fantastic remedies to cure diseases feared by everybody because of their possible fatal outcome, or those cure all substances that may solve more than one hundred health problems is unfortunately frequent on Internet and creates false expectations in patients, relatives and even health professionals.
