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

A Hierarchical Transformer Encoder to Improve Entire Neoplasm Segmentation on Whole Slide Image of Hepatocellular Carcinoma [PDF]

open access: yesarXiv, 2023
In digital histopathology, entire neoplasm segmentation on Whole Slide Image (WSI) of Hepatocellular Carcinoma (HCC) plays an important role, especially as a preprocessing filter to automatically exclude healthy tissue, in histological molecular correlations mining and other downstream histopathological tasks.

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.

β‐Glucuronidase‐Expressing Lactobacillus reuteri Triggers Irinotecan Enterotoxicity Through Depleting the Regenerative Epithelial Stem/Progenitor Pool

open access: yesAdvanced Science, EarlyView.
XLP mitigated CPT11 mucositis by suppressing GUS‐expressing microbes, notably L. reuteri, and diminishing bacterial GUS activity, consequently reducing SN38 accumulation to protect the intestinal epithelium. This preservation of the mucosal stem cell niche enabled rapid regeneration of secretory lineages such as mucin‐producing goblet cells, which ...

Inhibiting FAT1 Blocks Metabolic Bypass to Enhance Antitumor Efficacy of TCA Cycle Inhibition through Suppressing CPT1A‐Dependent Fatty Acid Oxidation

open access: yesAdvanced Science, EarlyView.
This study demonstrates that mutant FAT1 promotes ASCL2‐driven, CPT1A‐dependent fatty acid oxidation, leading to resistance to CPI‐613‐mediated TCA cycle inhibition in head and neck cancer. In vivo gene depletion of mutant FAT1 with LNP‐sgFAT1 suppresses tumor growth and restores CPI‐613 sensitivity, revealing a targetable metabolic bypass with ...
