Efficacy and Safety of Hypofractionated Radiation Therapy Combined With Immunotherapy for Hepatocellular Carcinoma With Vp4 Portal Vein Tumor Thrombosis

Hepatology Research, EarlyView.
ABSTRACT Background Hepatocellular carcinoma (HCC) with Vp4 portal vein tumor thrombosis (PVTT) has an extremely poor prognosis, and evidence for effective systemic therapy is limited. Preclinical studies suggest that hypofractionated radiation therapy (HFRT) may enhance immune checkpoint inhibitor (ICI) efficacy through immunogenic cell death and ...

Left breast irradiation with tangential intensity modulated radiotherapy (t-IMRT) versus tangential volumetric modulated arc therapy (t-VMAT): trade-offs between secondary cancer induction risk and optimal target coverage

Radiation Oncology, 2019
Adjuvant radiotherapy is the standard treatment after breast-conserving surgery. According to meta-analyses, adjuvant 3d-conventional irradiation reduces the risk of local recurrence and thereby improves long-term survival by 5–10%.

Linac-based VMAT radiosurgery for multiple brain lesions: comparison between a conventional multi-isocenter approach and a new dedicated mono-isocenter technique

Radiation Oncology, 2018
BackgroundLinac-based stereotactic radiosurgery or fractionated stereotactic radiotherapy (SRS/FSRT) of multiple brain lesions using volumetric modulated arc therapy (VMAT) is typically performed by a multiple-isocenter approach, i.e.

Outcome and Toxicity Profile of Stereotactic Body Radiation Therapy for Adrenal Tumours in Dogs

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Stereotactic body radiation therapy (SBRT) has become a non‐invasive alternative option for canine adrenal tumours with high surgical risks; however, its clinical benefits and risks are still to be fully understood. The goal of this multi‐institutional retrospective study was to describe the clinical outcome and safety of SBRT for the ...
