Investigadores del M.D. Anderson Cancer Center de la Universidad de Texas (Estados Unidos) muestran en los resultados de su estudio que los pacientes que recibieron quimioterapia neoadyuvante sobrevivieron de promedio 31 meses más que los tratados únicamente con cirugía. Entre estos últimos, el riesgo de morir a causa del tumor fue un 66% superior que entre los sometidos a quimioterapia neoadyuvante.
Según datos de la Sociedad Americana del Cáncer, cada año son diagnosticados de cáncer de vejiga más de 55.000 estadounidenses y fallecen más de 12.000.
Para los autores del estudio, los resultados obtenidos demuestran que la quimioterapia neoadyuvante constituye un importante avance, puesto que pone de manifiesto que conlleva una significativa mejoría en términos de supervivencia. En la investigación participaron 307 pacientes, la mitad de los cuales recibieron tratamiento con una combinación de metotrexato, vinblastina, doxorrubicina y cisplatino antes de ser intervenidos.
