Can Patient Characteristics and Pre-Treatment MRI Features Predict Survival After Stereotactic Ablative Radiotherapy (SABR) Treatment in Hepatocellular Carcinoma (HCC): Preliminary Assessment.

Background: The study purpose was to develop a machine learning (ML)-based predictive model for event-free survival (EFS) in patients with hepatocellular carcinoma (HCC) undergoing stereotactic ablative radiotherapy (SABR).

Methods: Patients receiving SABR for HCC at a single institution, between 2017 and 2020, were included in the study. They were split into training and test (85%:15%) cohorts.

Combination treatment of HCC with SBRT and immune checkpoint inhibition.

The treatment of unresectable or metastatic HCC has been significantly advanced in recent years by developments in both radiotherapy and systemic cancer therapies. Independently, both Stereotactic Ablative Body Radiotherapy (SBRT) and Immune Checkpoint Inhibitors (ICIs) are licensed for the treatment of these tumours. Building on the successes seen in other solid tumours, there is significant interest in exploring combination treatments.

British Society of Gastroenterology guidelines for the diagnosis and management of cholangiocarcinoma.

These guidelines for the diagnosis and management of cholangiocarcinoma (CCA) were commissioned by the British Society of Gastroenterology liver section. The guideline writing committee included a multidisciplinary team of experts from various specialties involved in the management of CCA, as well as patient/public representatives from AMMF (the Cholangiocarcinoma Charity) and PSC Support. Quality of evidence is presented using the Appraisal of Guidelines for Research and Evaluation (AGREE II) format.

Conformal 3D computed tomography planned endoluminal brachytherapy for the local control of esophageal cancer.

Purpose: To outline the toxicity, tolerability, and efficacy of a 3D conformal computed tomography planned endoluminal brachytherapy (ELBT) treatment for esophageal adenocarcinoma (OAC) or squamous cell carcinoma (OSCC).

Methods And Materials: A retrospective single-center analysis of toxicity, tolerability, and outcomes for 65 consecutive patients with OAC/OSCC who received 6-8Gy in one fraction or 12-16Gy in two fractions of high-dose-rate ELBT as salvage postchemoradiotherapy (n = 7 and n = 14 respectively), or as a boost to external beam radiotherapy (n = 14 and n = 30, respectively).

Results: Median overall survival from the first brachytherapy application was 7.
