Background: Lack of an ideal detector for small field dosimetry has led to the development of many new types of detectors. Recent studies have shown that plastic scintillation detectors (PSDs) provide favorable dosimetric characteristics, such as minimal volume averaging and fluence perturbation effects, real time response rates, high signal to noise ratio (SNR), and independence to temperature, energy spectrum, dose rate, and irradiation direction, in the field of small field dosimetry, largely due to their small size and water-equivalent composition materials, which eliminates the need for certain correction factors.
Purpose: The goal of this study was to evaluate a new 0.

Background: Recurrent ovarian cancer is often treated with chemotherapy, but many patients experience multiple recurrences with progressively shorter intervals and poorer prognosis. Repeated chemotherapy reduces patients' quality of life. Stereotactic Ablative Radiation Therapy for Recurrent Ovarian Cancer (SABR-ROC) (KGOG3064/KROG 2204) is an ongoing trial investigating the clinical efficacy of stereotactic ablative radiation therapy (SABR) for recurrent ovarian cancer.

Background And Objectives: Atypical and anaplastic meningioma (World Health organization [WHO] Grades II and III) present therapeutic challenges due to their aggressive behavior and high risk of recurrence. This study addressed the lack of data related to the effectiveness and safety of repeated stereotactic radiosurgery (SRS) in managing high-grade recurrent or residual meningioma.
Methods: This study analyzed data extracted from the medical records of 112 patients (mean age of 57.

Purpose: PSMA-PET/CT is frequently used for staging patients with de-novo or recurrent prostate cancer (PCa). In patients with oligometastatic PCa PSMA-PET/CT guided stereotactic ablative body radiotherapy (SABR) is a common treatment option. Follow-up is regularly performed via measurement of prostate-specific-antigen (PSA) level.

Background: Anaplastic ependymomas are malignant CNS tumors with poor prognosis. Chondroid metaplasia in ependymomas is extremely rare, and its clinical significance remains unclear.
Observations: A 21-year-old male underwent gross-total resection and adjuvant radiotherapy for an anaplastic ependymoma.
