PURPOSE Recent studies have suggested that the addition of adjuvant radiation therapy (aRT) may improve outcomes in men with pathologically involved lymph nodes (pN+). The objective of this study was to assess the treatment patterns and the overall survival (OS) outcomes in men with pN+prostate cancer using the National Cancer Data Base. METHODS Men(More)
AIMS To use the Surveillance, Epidemiology and End Results database in order to evaluate prostate biopsy concordance in a large population-based sample. METHODS We identified 34 195 men who were diagnosed with prostate cancer and underwent a radical prostatectomy from 2010 to 2011. All patients also had to have both clinical and pathological Gleason(More)
BACKGROUND The optimal management of patients with localized esophageal cancer is uncertain. The objective of this study was to analyze contemporary patterns of care for esophageal cancer using the National Cancer Database. METHODS Patients diagnosed with localized esophageal adenocarcinoma or squamous cell carcinoma from 2004 to 2011 and who received(More)
PURPOSE Endorectal balloons may be of benefit during stereotactic body radiation therapy of the prostate to limit intrafraction prostatic motion and potentially minimize rectal toxicity. We evaluated the effect of the endorectal balloon (ERB) on rectal dosimetry, specifically the absolute volume of rectum receiving high dose. METHODS AND MATERIALS Eleven(More)
OBJECTIVE Two randomized trials have demonstrated a local control advantage in the absence of a survival advantage for the addition of adjuvant radiation therapy (RT) to surgery in patients with stage I endometrial adenocarcinoma (EC). This study analyzed the National Cancer Data Base (NCDB) to evaluate the impact of adjuvant RT on overall survival (OS) for(More)
To study the impact of race in an equal access care institution with a predominantly African-American (AA) population. We retrospectively reviewed data from 222 men with low risk (LR) or intermediate risk (IR) prostate cancer who underwent radical prostatectomy at the New York Harbor VA between 2003 and 2011. Biochemical relapse, distant control, and(More)
PURPOSE Several prior studies have suggested that brachytherapy utilization has markedly decreased, coinciding with the recent increased utilization of intensity modulated radiation therapy, as well as an increase in urologist-owned centers. We sought to investigate the brachytherapy utilization in a large, hospital-based registry. MATERIAL AND METHODS(More)
BACKGROUND Evidence suggests that delaying surgical procedures may increase the rate of pathologic complete response (pCR) and that pCR is associated with improved overall survival (OS). In this study, the National Cancer Data Base (NCDB) was analyzed to evaluate this relationship in a large hospital-based registry. METHODS We identified patients(More)
Because of the rarity of esophageal melanoma, the optimal management of this disease is limited. The pooled dataset in the National Cancer Database (NCDB) was used to identify the prognostic factors and treatment outcomes. Patients who were diagnosed with esophageal melanoma between 2004 and 2011 were identified. Patients were stratified as either localized(More)
One thousand one hundred and sixty three patients (male-852, female-311) with ureteric calculi requiring intervention were treated between April 1988 to July 1992. Four hundred and eleven cases were treated by ESWL Monotherapy, 414 by stone manipulation plus ESWL, 301 by retrograde ureteroscopic lithotripsy, 36 by percutaneous antegrade ureteroscopic(More)
