Refining MR-guided thermal ablation for HCC within the Milan criteria: a decade of clinical outcomes and predictive modeling at a single institution.
BMC Cancer
January 2025
Department of Interventional Radiology, First Affiliated Hospital of Fujian Medical University, Fuzhou, 350000, China.
Background: The appropriateness of ablation for liver cancer patients meeting the Milan criteria remains controversial.
Purpose: This study aims to evaluate the long-term outcomes of MR-guided thermal ablation for HCC patients meeting the Milan criteria and develop a nomogram for predicting survival rates.
Methods: A retrospective analysis was conducted from January 2009 to December 2021 at a single institution.
Evaluation of parotid and submandibular salivary glands with ultrasonography in diabetic patients.

Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Zonguldak Bulent Ecevıt University, Zonguldak, Turkey.
Objectives: The main symptom of diabetes mellitus (DM) is hyperglycaemia, and patients with DM often have microvascular complications, such as retinopathy, neuropathy, and nephropathy; macrovascular complications, such as coronary heart disease, peripheral arterial disease and cerebrovascular disease; and oral complications, such as xerostomia, hyposalivation and periodontal disease. The main aim of this study was to evaluate the submandibular and parotid glands in type 2 DM patients and healthy individuals and to determine the changes in the salivary glands caused by diabetes.
Materials And Methods: In this study, the salivary glands of 100 patients (50 individuals with type 2 DM and 50 healthy individuals) were evaluated by ultrasonography (US).
Spatial accuracy of dose delivery significantly impacts the planning target volume margin in linear accelerator-based intracranial stereotactic radiosurgery.

Radiation Safety and Quality Assurance division, National Cancer Center Hospital East, Chiba, 277-8577, Japan.
The impact of three-dimensional (3D) dose delivery accuracy of C-arm linacs on the planning target volume (PTV) margin was evaluated for non-coplanar intracranial stereotactic radiosurgery (SRS). A multi-institutional 3D starshot test using beams from seven directions was conducted at 22 clinics using Varian and Elekta linacs with X-ray CT-based polymer gel dosimeters. Variability in dose delivery accuracy was observed, with the distance between the imaging isocenter and each beam exceeding 1 mm at one institution for Varian and nine institutions for Elekta.

Objective: The study aimed to evaluate the accuracy and safety of the semi-active robotic system for implant placement in atrophic posterior maxilla.
Methods: Patients underwent robot-assisted implant placement in atrophic posterior maxilla were identified and included. Cone-beam computed tomography (CBCT) was performed before surgery.
Prognostic significance of the retroperitoneal surgical resection margin on computed tomography colonography in retroperitonealized colon cancer.

Department of Colorectal Surgery, National Cancer Center Hospital, Tokyo, Japan. Electronic address:
Background: A positive pathologic retroperitoneal surgical resection margin in the retroperitonealized colon is reported to predict distant metastases. However, no studies have investigated retroperitoneal surgical resection margin positivity on computed tomography colonography and its prognostic significance.
Methods: Patients who underwent primary resection for ascending or descending colon cancer at our institution between 2013 and 2018 were retrospectively evaluated (n = 206).
