Radiofrequency Ablation Versus Stereotactic Body Radiotherapy for Localized Hepatocellular Carcinoma in Nonsurgically Managed Patients: Analysis of the National Cancer Database.

Purpose Data that guide selection of optimal local ablative therapy for the management localized hepatocellular carcinoma (HCC) are lacking. Because there are limited prospective comparative data for these treatment modalities, we aimed to compare the effectiveness of radiofrequency ablation (RFA) versus stereotactic body radiotherapy (SBRT) by using the National Cancer Database. Methods We conducted an observational study to compare the effectiveness of RFA versus SBRT in nonsurgically managed patients with stage I or II HCC.

Intravascular large B-cell lymphoma in the United States (US): a population-based study using Surveillance, Epidemiology, and End Results program and National Cancer Database.

A population-based study of intravascular large B-cell lymphoma (IVLBCL) in the US was conducted to determine incidence, demographic and clinical characteristics, prognostic factors, and survival compared with diffuse large B-cell lymphoma not otherwise specified (DLBCL NOS). In the years 2000-2013, the age-adjusted incidence rate of IVLBCL was 0.095 (case/1,000,000).
