Purpose Accelerated tumor repopulation has significant implications in low–dose rate (LDR) brachytherapy. Repopulation onset time remains undetermined for cervical cancer. The purpose of this study was to determine the onset time of accelerated rep

Melanoma brain metastasis poses a difficult ther- apeutic challenge. Melanoma is perceived as a radioresistant histology and is thought to be less responsive to whole brain radiotherapy (WBRT). Stereotactic radiosurgery (SRS) is regarded as one of th

Brain metastases from radioresistant histologies are perceived to be less responsive to WBRT compared to other histologies, and stereotactic radiosurgery (SRS) may provide better local control. The aim of this study was to examine the outcomes of pat

Background To investigate outcome prediction by measuring tumor absolute volume and regression ratio using serial magnetic resonance imaging (MRI) during radiation therapy (RT) of cervical cancer and to develop algorithms identifying patients at risk

Purpose: To examine the outcomes of patients with a single brain metastasis from radioresistant histologies (renal cell carcinoma and melanoma) treated with stereotactic radiosurgery (SRS) with or without whole brain radiotherapy (WBRT). Methods and

The purpose of this work was to determine alternative radiotherapy (RT) regimens that are biologically equivalent to clinically proven treatments using different RT modalities or different fractionation schemes. The concept of equivalent uniform dose

Purpose To evaluate whether real-time intraoperative ultrasound (US)-based dosimetry can replace conventional postoperative computed tomography (CT)-based dosimetry in prostate brachytherapy. Methods and Materials Between December 2001 and November 2
