Resumen

La calidad de vida relacionada con salud (CVRS) se refiere a la evaluación que hace el paciente de su estado actual de funcionamiento y satisfacción comparado con aquel que se percibe como ideal. La medición de la calidad de vida en ensayos clínicos provee una evaluación mas precisa de qué tan bien se sienten los individuos o grupos de pacientes y los beneficios y eventos adversos que puedan ser resultado de la intervención médica. En la investigación oncológica, la calidad de vida ha sido identificada como el segundo desenlace primario más importante luego de la supervivencia. Para determinar cómo se está evaluando la calidad de vida en ensayos clínicos en cáncer, se realizó una búsqueda en las bases de datos MedLine y LILACS. Luego de una selección basada en criterios de elegibilidad, se escogieron 192 artículos. El primer ensayo clínico que incluye una medición de calidad de vida se publicó en 1992; la neoplasia más frecuentemente estudiada fue el cáncer de mama, mientras que en el cáncer colo-rectal se observa una tendencia hacia la disminución de estudios que miden la calidad de vida. Se encontraron cinco trabajos en los que se utilizaron instrumentos no específicos para medir el constructo. Debido a la relevancia que tiene la calidad de vida, es necesario generar investigaciones similares, con el fin de evaluar estas mediciones en otros tipos de estudios epidemiológicos y en otras patologías.

Palabras clave:

Abstract

Health Related Quality of Life (HRQL) refers to the evaluation a patient makes of his/her current functional state and sense of well-being compared to the ideal. The measurement of quality of life in clinical trials (CT) provides a more accurate evaluation on how well individual patients or groups of patients feel, and what benefits and adverse events might occur as a result of medical intervention. In oncological research, quality of life has been identified as the second most important outcome, preceded only by survival. In order to establish how quality of life evaluation was being carried out on clinical trials for cancer, we conducted a data base search at MEDLINE and LILACS. Following selection based upon elegibility criteria, 192 articles were chosen. The first CT to measure quality of life were published in 1992; the most frequently studied neoplasia was breast cancer; in the case of colorectal cancer, the trend was towards fewer quality of life measurement studies. Five studies were found in which non-specific instruments were utilized to measure the construct. Due to the relevance of quality of life, it is necessary to carry out similar searches to evaluate these measurements in other kinds of epidemilogical and pathological studies.
