A prospective, comparative analysis of acute toxicity profile between three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy (IMRT) in locally advanced head and neck cancer patients.

Introduction: The advances of modern radiotherapy have emerged with the development of conformal radiotherapy techniques, such as the three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy (IMRT). We prospectively compared acute toxicities and treatment-compliance between IMRT and 3DCRT in patients with locally advanced head and neck carcinoma.

Method: 80 patients were enrolled in this comparative prospective non-randomized study.

Assessment of three-dimensional setup errors in image-guided pelvic radiotherapy for uterine and cervical cancer using kilovoltage cone-beam computed tomography and its effect on planning target volume margins.

Purpose: To achieve the best possible therapeutic ratio using high-precision techniques (image-guided radiation therapy/volumetric modulated arc therapy [IGRT/VMAT]) of external beam radiation therapy in cases of carcinoma cervix using kilovoltage cone-beam computed tomography (kV-CBCT).

Materials And Methods: One hundred and five patients of gynecological malignancies who were treated with IGRT (IGRT/VMAT) were included in the study. CBCT was done once a week for intensity-modulated radiation therapy and daily in IGRT/VMAT.
