Dosimetry for Dose Verification of Total Skin Electron Beam Therapy Using Gafchromic® EBT3 Film Dosimetry.

Background And Purpose: Total skin electron beam therapy (TSEBT) is an important skin-directed radiotherapeutic procedure done in the treatment of cutaneous T-cell lymphomas, namely, mycosis fungoides (MF). This procedure is usually done at larger source-to-surface distances with the patient standing on a rotatory platform. As the patient has to stand in different positions without any rigid immobilization devices, there are chances that the total skin may not get uniformly irradiated which could lead to nonuniform dose distributions.

Skin Sparing in Intensity-Modulated Radiation Therapy of Nasopharyngeal Carcinoma.

Background And Purpose: Radiation therapy of nasopharyngeal carcinomas (NPCs) involves high doses to the target structures which are superficial to the skin surfaces. As a result, the skin toxicities involved are higher and sometimes worsens to such an extent that radiotherapy needs to be interrupted unplanned. This leads to a break in radiation therapy which overall affects the local control and cure rates.

To evaluate the use of tandem and cylinder as an intracavitary brachytherapy device for carcinoma of the cervix with regard to local control and toxicities.

Introduction: Brachytherapy always remains a keystone in the treatment of gynecological carcinoma for both definitive and adjuvant treatments. Due to the rapid fall-off nature of brachytherapy, the target gets a high dose with a low dose to the normal organs nearby and thereby increasing the tumor control probability.

Aims And Objectives: This study aims at the evaluation of local control and toxicities in the carcinoma of the cervix using tandem and cylinder as brachytherapy applicator.

quality assurance of three-dimensional conformal radiotherapy mono-isocentric plan for simultaneous treatment of two targets.

Objective: The purpose of this study was to check the efficacy of a radiotherapy plan generated for the treatment of two femoral targets simultaneously in the pelvis.

Methods: The target positions for conformal radiotherapy were simulated by joining two identical water phantoms (approximating the patient dimensions), and a treatment plan to treat the two targets simultaneously with a common isocenter was planned. Calculations were made with a dose prescription of 300cGy to each lesion.

Modality of Radiotherapy and Overall Survival in Pediatric Diffuse Brainstem Gliomas: Implications for Resource-Constrained Settings.

Background: Childhood diffuse brainstem glioma (dBSG) is a rare tumor with a poor prognosis. Any tumor-directed surgical intervention is difficult. Magnetic resonance imaging forms the mainstay of diagnosis and radiation therapy has remained the backbone of therapy.
