Evaluation of Nutritional Status and Anxiety Levels in Patients Applying to the Radiation Oncology Outpatient Clinic during the COVID-19 Pandemic: Turkish Society for Radiation Oncology Group Study (TROD 12:02).

Cancer patients often face malnutrition, which negatively affects their response to cancer treatment. This study aims to analyze the effects of the COVID-19 pandemic on nutritional status and anxiety in cancer patients with different types and stages of cancer. This is a cross-sectional cohort study that includes 1,252 patients with varying cancer types from 17 radiation oncology centers.

Stereotactic body radiotherapy as a boost after external beam radiotherapy for high-risk prostate cancer patients.

Background: The effect of high-dose-rate (HDR) brachytherapy after external radiation in high-risk prostate cancer patients has been proven. Stereotactic body radiotherapy as a less invasive method has similar dosimetric results with HDR brachytherapy. This study aims to evaluate the prostate-specific antigen (PSA) response, acute side effects, and quality of life of patients who underwent stereotactic body radiotherapy (SBRT) as a boost after pelvic radiotherapy (RT).

Hyperfractionated accelerated radiotherapy in locally advanced head and neck cancers.

Purpose: Head and neck cancers are rapidly proliferating and relatively radiosensitive tumors. The increase in the number of daily fractions and the decrease in total treatment time give promising results in clinical practice.

Patients And Methods: 20 patients diagnosed with head and neck cancer between August 2000 and July 2001 participated in this study.
