CRT

A radiation delivery method called tomotherapy may be more effective than conformal radiation therapy at keeping mesothelioma tumors from growing back at the original spot after surgery. That is the conclusion of UCLA researchers who compared tomotherapy and 3D conformal radiation therapy (CRT) in 45 patients with advanced pleural mesothelioma over an 8 year period. Of the forty-five consecutive patients, 23 received 3D-CRT and the other 22 received tomotherapy. Kaplan-Meier analysis was used to calculate overall survival, the time it took for a tumor to start regrowing in the same place, and the time it took for metastatic tumors to start appearing outside of the treatment field. Tomotherapy and 3D-CRT are both methods of delivering radiation into a mesothelioma tumor…
