BACKGROUND: The primary treatment of early stage cervical carcinoma (IB-IIA) is either surgery or radiation therapy based on the pivotal Milan randomized study published twenty years ago. In the presence of high-risk features, the gold standard treatment is concurrent chemotherapy and radiation therapy (CRT) whether it is the in the postoperative or the definitive setting. Using the National Cancer Data Base (NCDB), the goal of our study is to compare the outcomes of surgery and radiation therapy in the chemotherapy era...

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 (T1-4N0M0), regional (T1-4N+M0), or metastatic (M1). The primary endpoint of this study was overall survival (OS) which was analyzed using the Kaplan-Meier method and multivariate Cox regression, which was performed to identify potential factors influencing survival...

Given the paucity of esophageal small cell carcinoma (SCC) cases, there are few large studies evaluating this disease. In this study, the National Cancer Data Base (NCDB) was utilized to analyze the clinical features, treatment, and survival of patients with esophageal SCC in a large, population-based dataset. We selected patients diagnosed with esophageal SCC from 1998 to 2011. Patients were identified as having no treatment, chemotherapy alone, radiation ± sequential chemotherapy, concurrent chemoradiation, and esophagectomy ± chemotherapy and/or radiation...

BACKGROUND: Radical cystectomy (RC) is used to treat select patients with T1 high-grade (T1HG) bladder cancer. However, population-level utilization trends and outcomes for these patients are not well-known. We sought to evaluate treatment patterns and clinicopathologic outcomes of RC for T1HG bladder cancer. PATIENTS AND METHODS: Using the National Cancer Data Base (NCDB) for 1998-2012, we conducted a retrospective cohort study of patients with clinical T1HG bladder cancer...

PURPOSE: Adjuvant radiation therapy (RT) was shown to improve local control in patients with high-intermediate risk (HIR) stage I endometrial cancer (EC) in randomized trials. Overall survival (OS) was not significantly different with adjuvant RT in these trials or subsequent meta-analyses; however, they were underpowered to assess OS. We used the National Cancer Data Base (NCDB) to examine the impact of adjuvant RT on OS in HIR EC patients. METHODS: The NCDB was queried for patients diagnosed with FIGO (2009) Stage I endometrioid adenocarcinoma from 1998 to 2012 who underwent surgery±adjuvant RT...

BACKGROUND: Stage II and III rectal cancers have been effectively treated with neoadjuvant chemoradiotherapy (NCRT) followed by definitive resection. Advancements in surgical technique and systemic therapy have prompted investigation of neoadjuvant multiagent chemotherapy (NMAC) regimens with the elimination of radiation (RT). The objective of the current study was to investigate factors that predict for the use of NCRT versus NMAC and compare outcomes using the National Cancer Data Base (NCDB) for select stage II and III rectal cancers...

OBJECTIVE: To determine overall survival (OS) and factors associated with OS of women with Mullerian adenosarcoma. METHODS: Women with adenosarcoma of the uterus, cervix or ovary (n=2205) were identified from the 1998-2011 National Cancer Data Base. Kaplan-Meier and multivariate Cox proportional-hazards survival analyses were performed to test for associations of potential explanatory variables with OS. A subset analysis of women with uterine adenosarcoma was also performed...

INTRODUCTION: A subset of patients with potentially resectable clinical stage IIIA non-small cell lung cancer (NSCLC) are managed with trimodality therapy. However, little data exist to guide the timing of surgery after neoadjuvant therapy. This study examined whether the time interval between neoadjuvant chemoradiation (NCRT) and surgical resection impacts overall survival. METHODS: Clinical stage IIIA disease (T1-3 N2) NSCLC patients who underwent neoadjuvant chemoradiation therapy were identified in the National Cancer Data Base (NCDB) between 2004-2012 and categorized based on the interval between chemoradiation and surgery (0 to ≤3, 3 to ≤6, 6 to ≤9, and 9 to ≤12 weeks)...

OBJECTIVE: To identify prognostic and treatment factors for primary urethral cancer using a nationwide database. MATERIALS AND METHODS: The National Cancer Database (NCDB) was queried for all cases of primary urethral cancer from 2004-2013. Patients with other cancer diagnoses, metastasis or diagnosis on autopsy we excluded. Proportional hazards regression was used to identify independent predictors of overall survival in patients with primary urethral cancer. Because we hypothesized that predictors may covary by sex, we also performed regression analysis stratified by sex...

BACKGROUND: Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive malignancy of unknown etiology with a poor overall prognosis. Its relative rarity has made it difficult to determine the impact of different treatment modalities on survival. METHODS: Retrospective study of cases in the National Cancer Data Base (NCDB). NCDB cases that were diagnosed as having SNUC between January 1, 2004, and December 31, 2013 were included in the analysis. Outcomes of patients treated with surgery followed adjuvant chemoradiotherapy were compared with definitive chemoradiotherapy...
