Journal for Immunotheraphy of Cancer<\/em><\/a>, analiza 374 muestras metast\u00e1sicas de los cuatro \u00f3rganos secundarios m\u00e1s propensos a ser invadidos por c\u00e9lulas tumorales diseminadas (cerebro, huesos, h\u00edgado y pulm\u00f3n), y pertenecientes a c\u00e1nceres originados en ubicaciones primarias diferentes.<\/p>\n\u201cLos an\u00e1lisis bioinform\u00e1ticos realizados han refutado la hip\u00f3tesis \u201csemilla y tierra\u201d y revelaron que los tumores metast\u00e1sicos ubicados en los pulmones, independientemente delalocalizaci\u00f3n primaria<\/strong> del c\u00e1ncer, comparten caracter\u00edsticas de inflamaci\u00f3n e infiltraci\u00f3n inmune. Por lo tanto, podr\u00edan responder a un mismo tratamiento <\/strong>con inmunoterapia\u201d, asegura Sandra Garc\u00eda-Mulero, primera autora del trabajo.<\/p>\nAdem\u00e1s, se encontraron diferencias significativas<\/strong> entre los perfiles inmunes de las met\u00e1stasis en distintos \u00f3rganos.En el h\u00edgado, la met\u00e1stasis tiende a ser muy poco inmunog\u00e9nica, es decir, que apenas activa el sistema inmunitario. Por el contrario, los resultados mostraron que la met\u00e1stasis en los pulmones <\/strong>tiende a ser altamente inmunog\u00e9nica e induce una reacci\u00f3n inflamatoria. Una de las hip\u00f3tesis que explicar\u00eda la susceptibilidad de los pulmones a la met\u00e1stasis seria que, para evitar una reacci\u00f3n inmune masiva, los propios pulmones podr\u00edan activar mecanismos inmunosupresores, y los tumores aprovechar\u00edan esta situaci\u00f3n para facilitar la met\u00e1stasis.<\/p>\nA la hora de plantear una terapia para este tipo de tumores metast\u00e1sicos altamente inflamatorios se podr\u00eda considerar el tratamiento con bloqueadores, que permitir\u00eda la respuesta inmunitaria de los pulmones, favoreciendo la destrucci\u00f3n de c\u00e9lulas cancerosas.<\/p>\n","protected":false},"excerpt":{"rendered":"
