Article Synopsis
- PreciseART is an adaptive radiation therapy software integrated into the Precision treatment planning system that monitors dose variations during cancer treatment.
- The study compared PreciseART’s automatic dose recalculation with a traditional treatment planning system, finding no significant differences in accuracy for both phantom and patient studies.
- The notification system of PreciseART effectively alerts users about dose compliance, confirming its usefulness in clinical adaptive radiation therapy.
Purpose: This study aims to introduce modified fixed field volumetric modulated arc therapy (MF-VMAT) which manually opened the field size by fixing the jaws and comparing it to the typical planning technique, auto field volumetric modulated arc therapy (AF-VMAT) in cervical cancer treatment planning.
Methods And Materials: Previously treated twenty-eight cervical cancer plans were retrospectively randomly selected and replanned in this study using two different planning techniques: AF-VMAT and MF-VMAT, resulting in a total of fifty-six treatment plans. In this study, we compared both planning techniques in three parts: (1) Organ at Risk (OARs) and whole-body dose, (2) Treatment plan efficiency, and (3) Treatment plan accuracy.
Objective: This retrospective study evaluated the preliminary outcomes of image-guided vaginal brachytherapy (IG-VBT) in the adjuvant treatment of high intermediate risk endometrial cancer.
Materials And Methods: Data were collected from 48 patients who underwent adjuvant IG-VBT between 2019 and 2022 at the Division of Radiation Oncology, Department of Radiology, Faculty of Medicine, Chiang Mai University. The vaginal cuff clinical target volume (CTV-VC) is composed of a 4-mm-thick band around vaginal cylinder at the upper 3 cm of the vaginal cuff.
Article Synopsis
- The study tracked 12 years of a quality assurance program in radiation oncology to enhance patient safety and reduce treatment errors.
- The Quality Assurance Program (QUAPRO) included a three-step process to identify near-misses during the treatment phases and transitioned to an electronic system by 2017 for better tracking.
- Results showed that while the rate of near misses initially fluctuated, the integration of electronic records improved detection, ultimately leading to a significant decrease in near misses due to enhancements in the workflow.
The dose expansion methods as the skin flash and virtual bolus were used to solve intrafraction movement for breast planning due to breathing motion. We investigated the skin dose in each planning method by using optically stimulated luminescence on an in-house moving phantom for breast cancer treatment in tomotherapy. The impact of respiratory motion on skin dose between static and dynamic phantom's conditions was evaluated.

This study is not only analyzing the plan quality by utilizing the plan parameters and indexes but also compares treatment modalities from the protocol implementation.
Method And Material: Twenty-five patients treated in the period from February 2020 to September 2022 were recruited in this analysis.
Survival outcome of cervical cancer patients treated by image-guided brachytherapy: a 'real world' single center experience in Thailand from 2008 to 2018.

The objective of our study was to evaluate the survival outcome of cervical cancer patients treated using image-guided brachytherapy (IGBT). From 2008 to 2018, 341 patients with cervical cancer were treated by radical radiotherapy. IGBT (by computed tomography [CT] or transabdominal ultrasound [TAUS]) was used to treat all of these patients.

Materials And Methods: For each of the seventeen patients included in the study, two treatment plans (i.e.
Article Synopsis
- The study aimed to assess the cumulative radiation dose at point A using 3 cm and 4 cm central shielding.
- After applying the shielding to a standard radiotherapy plan, the cumulative doses were calculated in EQD2 for both shielding types.
- Results indicated that 3 cm central shielding resulted in a higher cumulative dose at point A compared to 4 cm central shielding.
