PURPOSE A meta-analysis is presented comparing the overall survival (OS) and local control (LC) rates between penectomy and brachytherapy for penile cancer. METHODS AND MATERIALS A PUBMED search was conducted with the MeSH terms, "penis, penile, cancer, brachytherapy, penectomy, surgery, treatment" in various combinations. Nineteen retrospective studies(More)
Stereotactic body radiation therapy (SBRT) is an emerging technology for the treatment of spinal metastases, although the dosimetric impact of the calculation method on spinal dose distribution is unknown. This study attempts to determine whether CyberKnife (CK)-based SBRT using a Ray Tracing (RyTc) algorithm is comparable dosimetrically to that of Monte(More)
As stereotactic body radiation therapy (SBRT) for gastrointestinal (GI) gains popularity, there is a need to optimize doses and fractionation to minimize GI toxicity. GI organs that have classically developed radiation-induced toxicity include the liver & biliary system, small bowel, esophagus, and rectum. While the literature quantifies dose restrictions(More)
PURPOSE To define prognostic factors associated with improved survival and local control (LC) for gynecologic cancer recurrences limited to the pelvis and para-aortic (PA) region using stereotactic body radiation therapy (SBRT). METHODS Between 2/2008 and 7/2014, 30 women (35 targets) with pelvic or PA recurrence of endometrioid (n = 12), cervical (n =(More)
The benefit of whole-brain radiation therapy (WBRT) following stereotactic radiation surgery (SRS) for brain metastases is controversial. We conducted a systematic analysis of published literature to explore the outcome of brain metastases treated with SRS and WBRT versus SRS alone using PubMed and MEDLINE. Outcomes including survival, control, salvage(More)
PURPOSE To analyze the effect of post-radiation therapy (XRT) mammographic timing and radiation technique in relation to additional downstream workup for 569 breast conservation therapy patients treated with adjuvant XRT after their initial surveillance mammogram (MMG). METHODS AND MATERIALS From January 2011 to December 2014, 569 breast cancer patients(More)
BACKGROUND Atypical meningiomas (AMs) frequently recur after gross total resection (GTR). OBJECTIVE We conducted a meta-analysis to evaluate the benefit of adjuvant therapy after GTR of AMs. METHODS A PubMed/MEDLINE search identified studies detailing AMs treated by GTR alone or GTR and adjuvant radiotherapy (RT) published between 1984 and 2012.(More)
OBJECTIVE A systematic review of the literature was undertaken to investigate whether adjuvant radiotherapy and/or chemotherapeutics offered any additional benefit than surgery alone in the treatment of Merkel Cell Carcinoma (MCC). METHODS A PubMed, MEDLINE search was conducted between 1995 and 2013, to identify reported cases of surgically treated MCC(More)
In 2016, a projected 30,000 to 40,000 Americans will be diagnosed with small cell lung cancer (SCLC), and approximately 10% to 20% of them will have brain metastasis at time of diagnosis. The intrinsic radiosensitivity and propensity of SCLC to metastasize intracranially provides the rationale for whole brain radiation therapy (WBRT), either(More)
BACKGROUND The current standard of care for salvage treatment of glioblastoma multiforme (GBM) is gross total resection and adjuvant chemoradiation for operable patients. Limited evidence exists to suggest that any particular treatment modality improves survival for recurrent GBM, especially if inoperable. We report our experience with fractionated(More)
