Uno de cada cuatro pacientes con cáncer de pulmón en Andalucía debería recibir radioterapia y no lo hace
Uno de cada cuatro pacientes con cáncer de pulmón en Andalucía debería recibir radioterapia y no lo hace, según sostiene un estudio realizado por investigadores de la Universidad de Granada (UGR) y del Hospital Virgen de las Nieves de la capital granadina, que ha revelado así que los hospitales públicos andaluces «utilizan menos la radioterapia» en el tratamiento de pacientes con tumor de pulmón «de lo que marcan los protocolos clínicos».En concreto, este trabajo apunta a que la radioterapia la emplean un 25 por ciento menos de lo que se debería, lo que se traduce, según las estimaciones de los autores de esta investigación, «en más de 3.000 meses de pérdida en supervivencia para el conjunto de pacientes diagnosticados de cáncer de pulmón por culpa de este no tratamiento».Para llevar a cabo este trabajo, publicado en el último número de la revista ‘Journal of Thoracic Oncology’, sus autores revisaron las historias clínicas y el tratamiento de todos los pacientes sometidos a radioterapia para el cáncer de pulmón en 2007 en los 12 hospitales públicos andaluces que cuentan con instalaciones de radioterapia.Los datos fueron agrupados según el tipo de hospital, paciente, las características del tratamiento, el tipo histológico y el estado del tumor. Este hecho es un muy significativo, ya que otros estudios similares hacen referencia a encuestas o a datos de registros agregados.ESTUDIO CON 3.051 PACIENTESDe los 3.051 pacientes diagnosticados con cáncer de pulmón analizados, 610 fueron tratados con radioterapia inicial con una tasa de radiación global del 20 por ciento, cuando la tasa de radiación recomendada según sus historiales hubiera sido de 1.383 pacientes. De este modo, 773 pacientes con cáncer de pulmón más (es decir, un 25%) debería haber sido tratado con radioterapia y no lo fue.Como explica el profesor de la UGR José Expósito, la radioterapia tiene «un papel definido y claro en el tratamiento del cáncer de pulmón» y, de acuerdo con la literatura científica, «puede establecerse el porcentaje de pacientes que ‘deben’ recibir radioterapia, en función del estadiaje, del tipo histológico y otras consideraciones».Los estudios desarrollados por el grupo del profesor canadiense Mackillop, con el que han trabajado los investigadores de la UGR, estiman además la aportación neta en términos de meses de supervivencia que la radioterapia puede aportar en cada situación clínica. En este artículo, los investigadores han analizado, mediante test de regresión, las variables de las que puede depender esta diferencia entre los pacientes que deberían recibir radioterapia y los que realmente la reciben. «Esta variación puede deberse tanto a cierto déficit en equipamiento (unidades de radioterapia y profesionales), como a los estilos de práctica (preferencias) de los especialistas», ha concluido Expósito.
