IN TRAOPERATIVE RADIATION THERAPY FOR GASTRIC ADENOCARCINOMA

Intraoperative radiation therapy (IORT) is a multidisciplinary approach in which residual tumors or tumor beds are directly irradiated during a surgical procedure. To evaluate its efficacy, from 1985, we conducted a prospective study including non-metastatic gastric adenocarcinoma treated by surgery, IORT (15 Grays) and postoperative external beam radiotherapy (44 Grays). Up to 1993, 51 ca...

3D-Conformal Radiation Therapy and Intensity-Modulated Radiation Therapy Techniques for Laryngeal Cancer Taking Parotid Glands as Organ at Risk

Background: Three-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) techniques are used for the treatment of patients with laryngeal cancer. Objective: This study aimed to investigate the effects of these 2 treatment techniques on the planning target volume (PTV) (laryngeal cancer), dose homogeneity, dose of organs at...
