A dosimetric analysis of intensity-modulated radiation therapy with bone marrow sparing for cervical cancer.
BACKGROUND/AIM The purpose of the present study was to compare intensity-modulated radiation therapy (IMRT) plan with (Bone Marrow Sparing (BMS) - IMRT) or without (normal-IMRT) an intention of avoiding bone marrow in order to minimize treatment-related toxicity. PATIENTS AND METHODS Computed tomography (CT) images of 10 consecutive postoperative cervical cancer patients were used. All patien...
متن کاملDosimetric comparison of intensity modulated and volumetric arc radiation therapy for gastric cancer
The aim of the present study was to compare radiotherapy treatment plans for gastric cancer using intensity-modulated radiotherapy (IMRT) and single/double-arc volumetric modulated arc therapy (SA/DA-VMAT) delivery techniques. A total of 29 postoperative gastric cancer patients were enrolled in this study and each patient was scheduled 5-field IMRT (5F-IMRT), 7-field IMRT (7F-IMRT), SA-VMAT and...
متن کاملEsophageal Cancer Radiation Therapy
Esophageal cancer often is asymptomatic until it has advanced or metastasized to distant organs, limiting treatment options. The 2 most common forms are squamous cell carcinomas that appear in the upper or midesophagus and esophageal adenocarcinomas that tend to occur lower in the esophagus or at the gastroesophageal junction. Since the 1980s higher rates of esophageal adenocarcinomas have been...
متن کاملRadiation therapy and esophageal cancer.
BACKGROUND Squamous cell carcinoma and adenocarcinoma account for more than 90% of all esophageal cancer cases. Although the incidence of squamous cell carcinoma has declined, the incidence of adenocarcinoma has risen due to increases in obesity and gastroesophageal reflux disease. METHODS The authors examine the role of radiation therapy alone (external beam and brachytherapy) for the manage...
متن کاملPredictive factors for acute radiation pneumonitis in postoperative intensity modulated radiation therapy and volumetric modulated arc therapy of esophageal cancer
BACKGROUND Radiation pneumonitis (RP) is a common side reaction in radiotherapy for esophageal cancer. There are few reports about RP in esophageal cancer patients receiving postoperative intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT). This study aims to analyze clinical or dosimetric factors associated with RP, and provides data for radiotherapy planni...
