Robotic stereotactic body radiotherapy for recurrent nasopharyngeal carcinoma.

Background: We aimed to evaluate the outcomes of patients reirradiated with stereotactic body radiotherapy for recurrent nasopharyngeal carcinoma (r-NPC) in our hospital.

Methods: We retrospectively analyzed 10 patients with r-NPC previously irradiated with definitive radiotherapy. Local recurrences were irradiated with a dose of 25 to 50 Gy (median: 26.

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).

The Impact of the Stage and Tumor Size on Rare Brain Metastasis of Cervical Cancer.

Aim: To investigate the clinical features, prognostic factors and survival times of cervical cancer patients with brain metastasis.

Material And Methods: We retrospectively reviewed the medical records of 820 patients with cervical cancer. Data were analyzed using SPSS version 12.
