Neoadjuvant versus adjuvant radiotherapy for centrally located hepatocellular carcinoma: a propensity score matching study based on two prospective phase II trials

Therapeutic Advances in Medical Oncology
Background: The prognosis of centrally located hepatocellular carcinoma (cl-HCC) was unsatisfactory when treated with surgery alone. Adjuvant radiotherapy (RT) and neoadjuvant radiotherapy have been reported to correlate with better disease-free survival

Parotid gland as an organ at risk in whole-brain radiation therapy: A retrospective comparison of 3D-CRT and IMRT techniques from a tertiary cancer center

Cancer Research, Statistics, and Treatment
Background: Regardless of primary malignancy, whole-brain radiation therapy (WBRT) is the preferred treatment for brain metastases. However, WBRT exposes the parotid glands to significant radiation.

Prediction of VMAT gamma passing rates using 3D CNNs based on leaf position analysis and gradient class activation mapping for plan complexity evaluation

Medical Physics, Volume 53, Issue 5, May 2026.
Background Volumetric Modulated Arc Therapy (VMAT) is a highly conformal radiotherapy technique that enables precise tumor irradiation while sparing surrounding healthy tissue. However, the high technical demands this technique places on Linear Accelerators (LinAc) necessitate reliable quality assurance (QA) tools.

A Bayesian Causal Model for Matrix‐Valued Exposures With Applications to Radiotherapy Planning

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT In radiotherapy for cancer, organs surrounding the target tumor, known as organs‐at‐risk (OARs), should be protected from excessive radiation to avoid toxicity. Radiation exposure to multiple OARs can be summarized using matrix‐valued dose‐volume histograms (DVH), and understanding the causal relationship between DVHs and toxicity outcomes can

Impact of Hormonal and Radiation Therapy on Bladder Outlet Obstruction in High‐Risk Localized Prostate Cancer: A Prospective Pressure‐Flow Study

International Journal of Urology, Volume 33, Issue 5, May 2026.
ABSTRACT Purpose There are few reports investigating urodynamic changes after radiotherapy and hormonal therapy (HT) for prostate cancer. We prospectively evaluated differences in bladder outlet obstruction (BOO) using pressure‐flow studies (PFS) before and after HT and radiotherapy in patients with high‐risk localized or locally advanced prostate ...
