PURPOSE: No direct comparisons between extreme hypofractionation and conventional fractionation have been reported in randomized trials for the treatment of localized prostate cancer. The goal of this study is to use a propensity score matched (PSM) analysis with the National Cancer Database (NCDB) for the comparison of stereotactic body radiation therapy (SBRT) and intensity modulated radiation therapy (IMRT) for organ confined prostate cancer. METHODS: Men with localized prostate cancer treated with radiation dose ≥72 Gy for IMRT and ≥35 Gy for SBRT to the prostate only were abstracted from the NCDB...

BACKGROUND: This study aims to compare the 7th and 8th editions of the AJCC/UICC TNM staging system for patients with papillary thyroid cancer (PTC) in two national patient cohorts. METHODS: Adult PTC patients undergoing surgery were selected from SEER (2004-2012) and NCDB (2004-2012). Staging criteria for the 7th and 8th AJCC/UICC editions were applied separately to both cohorts; survival probabilities were estimated using the Kaplan-Meier method. Multivariable Cox proportional hazards models were used to estimate the association of stage with survival in both settings...

BACKGROUND: Surgery remains the mainstay of treatment for sinonasal melanoma, but it is often difficult to obtain clear, negative margins. Therefore, patients often receive adjuvant radiation therapy (RT), however its impact on overall survival (OS) is not well understood. METHODS: Patients with surgically resected sinonasal melanoma were identified from the National Cancer Data Base (NCDB, n=696). Kaplan-Meier curves and parametric survival regression were used to analyze the impact of adjuvant RT on OS from surgery...

BACKGROUND: Studies of various prostate cancer patient cohorts found men receiving external-beam radiotherapy (EBRT) had higher mortality than men undergoing radical prostatectomy (RP). Conversely, a recent clinical trial showed no survival differences between treatment groups. We used the National Cancer Data Base (NCDB) to evaluate overall survival in intermediate-risk (T2b-T2c or Gleason 7 [grade group II or III] or prostate-specific antigen 10-20 ng/mL) prostate cancer patients undergoing EBRT with or without androgen deprivation therapy (ADT), RP, or no initial treatment...

Nationwide utilization of spinal stereotactic body radiotherapy (SBRT) is not known; to address this void, the National Cancer Data Base (NCDB) from 2004 to 2013 was used for analysis. Spinal SBRT was defined as 1-5 fractions (14-32Gy) delivered to the cervical, thoracic, lumbar or sacral spine. From 2004 to 2013, 1044 patients received spinal SBRT, most commonly in single-fraction (38%), three-fraction (26%) and five-fractions (25%). Metastatic spinal disease most commonly originated from the lung (34%), kidney (14%), and blood (9%)...

OBJECTIVES: Mucoepidermoid carcinoma (MEC) is an uncommon malignancy that most commonly occurs in the parotid gland followed by the minor salivary glands of the upper aerodigestive tract, most notably in the oral cavity (OC) and oropharynx (OP). Because of its rarity, few studies have been performed that are specific to MEC within the OC and OP. The objective of this study is to describe the tumor characteristics and prognostic features for MEC of the OC and OP. MATERIALS AND METHODS: The National Cancer Database (NCDB) was used for this study...
