Comparison of Thyroid Toxicity Profiles in Head and Neck Cancer Patients Irradiated by 3D-Conformal Radiation Therapy and Intensity-Modulated Radiation Therapy

Medical Journal of Dr. D.Y. Patil Vidyapeeth
Background: In spite of recent technical advances in the radiation field, exposure to non-target organs such as the thyroid gland remains unavoidable in locally advanced head and neck cancer (LAHNC) planning, which is associated with late toxicities, and

Dosimetric comparison of two dose expansion methods in intensity modulated radiotherapy for breast cancer

Radiation Oncology, 2023
Background To explore the dosimetric difference between IMRT-VB plan based on the establishment of external expansion structure and virtual bolus (VB) and IMRT-SF based on the skin flash (SF) tool of the Eclipse treatment planning system in postoperative

Establishment of criteria for gamma-analysis of individual dose distributions during verification of radiotherapy high-tech treatment plans for cancer patients

Весці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2022
A typical process for verification of treatment plans in intensity-modulated radiation therapy is described. The main errors and uncertainties that arise in the course of planning dose distribution and in the process of dose delivery are listed.

Oncologic outcomes of IMRT versus CRT for nasopharyngeal carcinoma

Medicine, 2019
Background: Nasopharyngeal carcinoma (NPC) is a prevalent malignancy in Asia particularly southern China. Comparisons of outcomes of conformal radiotherapy (CRT) and intensity-modulated radiotherapy (IMRT) have been still debated.
