También recuerdan que seguir fumando afecta a la efectividad de los tratamientos, a la supervivencia global, al riesgo de desarrollar otros cánceres y a la calidad de vida.
Según el estudio, casi la mitad de los pacientes fumadores continúa fumando tras el diagnóstico o recae al poco tiempo de dejarlo. Por ello, los autores consideran que la cesación tabáquica constituye una herramienta infrautilizada en el manejo del cáncer y que muchos médicos fracasan a la hora de recomendar el abandono del tabaco.
Los investigadores realizaron una revisión de la literatura científica al respecto. Su trabajo demuestra que aquellos pacientes que abandonaron el consumo de tabaco en el momento del diagnóstico presentan mejores resultados en comparación con los que siguen fumando. La investigación muestra que la eficacia de los tratamientos oncológicos es menor en pacientes fumadores, sus efectos adversos son mayores y más graves, y las tasas de supervivencia menores. Asimismo, la calidad de vida es mejor en no fumadores.
