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 AND PURPOSE: Radiotherapy (RT) to the primary nasopharyngeal tumor is frequently offered to patients with metastatic nasopharyngeal carcinoma (mNPC). However, only limited data exist to support RT in this setting. We used the National Cancer Database (NCDB) to evaluate outcomes for mNPC patients receiving chemotherapy with and without local RT. METHODS: The NCDB was queried for patients with mNPC with synchronous metastatic disease at diagnosis who received chemotherapy...

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...

Acoustic neuroma (AN) management involves surgery, radiation, or observation. Previous studies have demonstrated that patient race and insurance status impact in-hospital morbidity/mortality following surgery; however the nationwide impact of these demographics on the receipt of each treatment modality has not been examined. The National Cancer Data Base (NCDB) from 2004 to 2013 identified AN patients. Multivariate analysis adjusted for several variables within each treatment modality, including patient age, race, sex, income, primary payer for care, tumor size, and medical comorbidities...

High-risk features are used to direct adjuvant therapy for stage II colon cancer. Currently, high-risk features are identified postoperatively, limiting preoperative risk stratification. We hypothesized carcinoembryonic antigen (CEA) can improve preoperative risk stratification for stage II colon cancer. The National Cancer Database (NCDB 2004-2009) was reviewed for stage II colon adenocarcinoma patients undergoing curative intent resection. A novel risk stratification including both traditional high-risk features (T4 lesion, <12 lymph nodes sampled, and poor differentiation) and elevated CEA was developed...

PURPOSE: To evaluate the effectiveness of radiation therapy among elderly patients who are deemed medically inoperable. METHODS AND MATERIALS: We searched PubMed to identify studies from the past 25 years that reported outcomes of medically inoperable endometrial cancer patients treated with radiation alone. The National Cancer Database (NCDB) was queried to identify patients 65 years and older with Stage I-II medically inoperable endometrial cancer. Univariable and multivariable models were performed to investigate the impact of prognostic factors on overall survival...

Differentiated thyroid cancer (DTC) with minimal extrathyroidal extension (MEE), is classified as stage III regardless of the tumor size. In this study, we aim to examine the effect of MEE on the overall survival and management of this population. Using a retrospective cohort study utilizing the National Cancer Data Base (NCDB), 2004-2012, the study population included patients, ≥ 45 years old, who underwent surgery for DTC (pT3N0M0) with MEE compared to patients with (pT2N0M0). We found a total of 9556 patients were included...
