Background: Gamma Knife ventral anterior capsulotomy is an effective option to treat refractory obsessive-compulsive disorder. Although well tolerated, complications can develop years after radiosurgery. We describe a case in which abnormal complications induced by very high doses of radiation evolved.

Case Description: A 55-year-old man with refractory obsessive-compulsive disorder was treated with Gamma Knife ventral anterior capsulotomy using a dose of 180 Gy. His obsessive-compulsive symptoms improved, but his condition evolved with a manic episode, cognitive memory changes, visual hallucinations, confabulation, and frontal lobe symptoms. Magnetic resonance imaging showed brain edema in the left hemisphere and a 6-mm brain cyst in the right hemisphere at postoperative month 20.

Conclusions: This case shows the consequences of affecting more fibers related to the anterior frontal region than intended with a radiosurgical procedure and illustrates the importance of careful clinical and imaging follow-up after Gamma Knife ventral anterior capsulotomy.

Background: Patients with non-small cell lung cancer (NSCLC) are prone to developing brain metastases (BMs), particularly those with epidermal growth factor receptor (EGFR) mutations. In clinical practice, treatment-naïve EGFR-mutant NSCLC patients with asymptomatic BMs tend to choose EGFR-tyrosine kinase inhibitors (TKIs) as first-line therapy and defer intracranial radiotherapy (RT). However, the effectiveness of upfront intracranial RT remains unclear.

Due to the better survival of patients with tumorous diseases, it is increasingly important to predict the side effects of radiotherapy, for which the Radiation-Induced Lymphocyte Apoptosis (RILA) method is proving to be effective in multicentric studies. Prostate cancer is the leading cause of cancer-related deaths among men worldwide, which is usually treated with radiotherapy. We recruited 49 patients with localized prostate cancer and performed RILA measurements before radiotherapy.

Catheter-based pulmonary artery denervation (PADN) has achieved promising outcomes to treat pulmonary hypertension (PH). We herein present stereotactic body radiotherapy (SBRT) as a novel noninvasive approach for PADN. A single fraction of 15 Gy, 20 Gy or 25 Gy was delivered for PADN in a thromboxane A2 (TxA2) - induced acute PH swine model.

Introduction Pediatric hemifacial spasm (HFS) is rare, presenting early in infancy, and often fraught with subsequent psychomotor and intellectual deficits. Fourth ventricular hamartoma (FVH) is a rare cause of HFS with only 5 cases reported in literature. While Gamma-knife radiosurgery (GKRS) has been used to treat hypothalamic hamartomas, this is the first case of FVH treated with primary GKRS.

Aims: Exploring fibrosis index-4 (FIB-4)'s predictive value for HBV-related hepatocellular carcinoma (HCC) in assessing recurrence following stereotactic body radiation therapy (SBRT) in patients with HBV-related HCC.

Methods: HBV-related HCC patients who underwent SBRT were retrospectively enrolled from March 2012 to March 2020. Patients were divided into recurrence and non-recurrence groups based on the HCC recurrence situation.
