Geometric and dosimetric evaluation of a commercial AI auto‐contouring tool on multiple anatomical sites in CT scans

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Current radiotherapy practices rely on manual contouring of CT scans, which is time‐consuming, prone to variability, and requires highly trained experts. There is a need for more efficient and consistent contouring methods. This study evaluated the performance of the Varian Ethos AI auto‐contouring tool to assess its potential integration into

Prognostic factors in conversion surgery following nab‐paclitaxel with gemcitabine and subsequent chemoradiotherapy for unresectable locally advanced pancreatic cancer: Results of a dual‐center study

open access: yesAnnals of Gastroenterological Surgery, Volume 7, Issue 1, Page 157-166, January 2023., 2023
For radical surgery after induction gemcitabine along with nab‐paclitaxel and subsequent chemoradiotherapy for unresectable locally advanced pancreatic ductal adenocarcinoma, CA19‐9 normalization and maintenance of good nutritional status during treatment until surgery were important for prolonged prognosis.

Facilitating 1.5T MR‐Linac adoption: Workflow strategies and practical tips

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background MR‐guided radiotherapy (MRgRT) offers new opportunities but also introduces workflow complexities requiring dedicated optimization. Implementing magnetic resonance linear accelerator (MR‐Linac) technology comes with challenges such as prolonged treatment times and workflow integration issues.

Do postoperative infectious complications really affect long‐term survival in colorectal cancer surgery? A multicenter retrospective cohort study

open access: yesAnnals of Gastroenterological Surgery, Volume 7, Issue 1, Page 110-120, January 2023., 2023
This multicenter retrospective cohort study suggested that postoperative infection (PI) after curative colorectal surgery (CRC) is associated with impaired oncological outcomes. Strategies to prevent PI and implement appropriate postoperative treatment may improve the quality of care and oncological outcomes in patients undergoing curative CRC surgery.

Machine learning for prediction of dose-volume histograms of organs-at-risk in prostate cancer from simple structure volume parameters [PDF]

open access: yesarXiv
Dose prediction is an area of ongoing research that facilitates radiotherapy planning. Most commercial models utilise imaging data and intense computing resources. This study aimed to predict the dose-volume of rectum and bladder from volumes of target, at-risk structure organs and their overlap regions using machine learning.

Quantification and dosimetric impact of intra‐fractional bladder changes during CBCT‐guided online adaptive radiotherapy for pelvic cancer treatments

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study quantitatively evaluates bladder changes and their dosimetric impact during the on‐couch adaptive process on a commercial CBCT‐based online adaptive radiotherapy (CT‐gART) platform. Methods Data from 183 fractions of ten patients receiving online ART for pelvic cancers were analyzed retrospectively.

Perioperative optimization of Crohn's disease

open access: yesAnnals of Gastroenterological Surgery, Volume 7, Issue 1, Page 10-26, January 2023., 2023
Most Crohn's disease patients require surgery during the course of their illness, especially those who experience complications. The management of perioperative medications and surgery‐related decision‐making should be individualized and patient‐centered based on a multidisciplinary approach.
