PURPOSE: A thorough understanding of the natural history and consensus regarding the optimal management of pathologic lymph node-positive (pN1) prostate cancer are lacking. Our objective was to describe patterns of care and outcomes of a contemporary cohort of men with pN1 prostate cancer. MATERIALS AND METHODS: The National Cancer Data Base (NCDB) was used to identify 7,791 men who were found to have LN metastases at the time of radical prostatectomy (RP). Multinomial logistic regression and Cox proportional hazards regression were used to identify patient, tumor and facility characteristics associated with choice of post-RP management strategy and overall survival (OS), respectively...

BACKGROUND: The role of chemoradiotherapy (CRT) in locally advanced pancreatic cancer (LAPC) is uncertain after multiple randomized clinical trials have yielded mixed results. The authors used the National Cancer Database (NCDB) to determine whether CRT yields a survival benefit compared with chemotherapy alone (CT). METHODS: Patients with nonmetastatic LAPC diagnosed during 2004 through 2014 were identified in the NCDB. Patients who received CT were compared with those who received CRT using chi-square analysis...

BACKGROUND: While previous studies have identified low socioeconomic status as a risk factor for metastatic disease in patients with high-grade osteosarcoma, the influence of socioeconomic status on overall survival remains unclear. The present study aims to investigate the relationship between survival and socioeconomic status in patients with high-grade conventional osteosarcoma. METHODS: The National Cancer Data Base (NCDB) was queried from 1998-2012 to identify all patients <40years of age with a diagnosis of high-grade conventional osteosarcoma...

The EORTC trial which solidified the role of external beam radiotherapy (EBRT) plus temozolomide (TMZ) in the management of GBM excluded patients over age 70. Randomized studies of elderly patients showed that hypofractionated EBRT (HFRT) alone or TMZ alone was at least equivalent to conventionally fractionated EBRT (CFRT) alone. We sought to investigate the practice patterns and survival in elderly patients with GBM. We identified patients age 65-90 in the National Cancer Data Base (NCDB) with histologically confirmed GBM from 1998 to 2012 and known chemotherapy and radiotherapy status...

BACKGROUND: As systemic therapy has improved for locally advanced pancreatic cancer (LAPC), efforts to improve local control with optimal radiotherapy may be critical. Although conventionally fractionated radiation therapy (CFRT) has more recently shown a limited role in LAPC, stereotactic body radiation therapy (SBRT) is an emerging approach with promising results. With no studies to date comparing SBRT with CFRT for LAPC, this study used the National Cancer Data Base (NCDB) to evaluate these 2 modalities...

For elderly patients with glioblastoma multiforme (GBM), randomized trials have shown similar survival with hypofractionated short-course radiotherapy (SCRT) compared to conventionally fractionated long-course radiotherapy (LCRT). We evaluated the adoption of SCRT along with associated factors and survival in a national patient registry. Using the National Cancer Data Base (NCDB), we identified patients aged ≥70 years with GBM, diagnosed between 1998 and 2011, who received SCRT (34-42 Gy in 2.5-3.4 Gy fractions), or LCRT (58-63 Gy in 1...

Performing randomised comparative clinical trials in radiation oncology remains a challenge when new treatment modalities become available. One of the most recent examples is the lack of phase III trials demonstrating the superiority of intensity-modulated radiation therapy in most of its current indications. A new paradigm is developing that consists in the mining of large databases to answer clinical or translational issues. Beyond national databases (such as SEER or NCDB), that often lack the necessary level of details on the population studied or the treatments performed, electronic health records can be used to create detailed phenotypic profiles of any patients...

BACKGROUND: Current guidelines recommend adjuvant chemotherapy for resected pancreatic adenocarcinoma (PDAC). However, no studies have addressed its survival benefit for stage I patients as they comprise <10% of PDAC. METHODS: Using the NCDB 2006-2012, resected PDAC patients with stage I disease who received adjuvant therapy (chemotherapy or chemoradiation) were analyzed. Factors associated with overall survival (OS) were identified. RESULTS: 3909 patients with resected stage IA or IB PDAC were identified...

For high-risk low-grade gliomas (LGGs), adjuvant radiotherapy (RT) with procarbazine/lomustine/vincristine (PCV) chemotherapy increases overall survival (OS) over RT alone. However, in practice, temozolomide (TMZ) is often used instead of PCV. Using the National Cancer Data Base (NCDB), we provide the first investigation of practice patterns and outcomes of chemoradiotherapy with single-agent chemotherapy (SAC, analogous to TMZ) or multi-agent chemotherapy (MAC, analogous to PCV) for LGG. Patients with high-risk Grade II LGGs were queried in the NCDB...

For cervical esophageal cancer (CEC), National Comprehensive Cancer Network guidelines support RT to 50-50.4 Gy with chemotherapy but acknowledge higher doses may be appropriate. This study uses the National Cancer Database (NCDB) to characterize RT practices and identify if a dose-response relationship exists for overall survival (OS) for definitive treatment of CEC. We queried the NCDB for patients diagnosed with Stage I-III CEC from 2004 to 2013, and selected patients receiving definitive RT with doses between 50 and 74 Gy...

BACKGROUND: Head and neck Merkel cell carcinoma (MCC) is commonly treated with surgery and adjuvant radiotherapy (RT) for high-risk features. The optimal radiation dose is unknown. METHODS: One thousand six hundred twenty-five eligible patients with head and neck MCC were identified in the National Cancer Data Base (NCDB). Radiation dose was divided into 3 groups: 30 to <50 Gray (Gy), 50-55 Gy, and >55-70 Gy. Cox regression was used to compare overall survival (OS) between groups, accounting for age, sex, stage, surgery type, margin status, comorbidities, and use of chemotherapy...
