Abstract null null Purpose null Concurrent chemoradiation plays an integral role in the treatment of esophageal cancer. Proton beam radiation therapy has the potential to spare adjacent critical organs, improving toxicity profiles and potentially improving clinical outcomes. null null null Methods and Materials null We evaluated the REG001-09 registry for patients undergoing proton radiation therapy for esophageal cancer. Demographic, clinicopathologic, toxicity, and dosimetry information were c...

INTRODUCTION The ACHOCC-19 study was performed to characterize COVID-19 infection in our oncological population. METHODOLOGY Analytical cohort study of patients with cancer and COVID-19 infection in Colombia. From April 1 to October 31, 2020. Demographic and clinical variables related to cancer and COVID-19 infection were collected. The primary outcome was 30-day mortality from all causes. The association between the outcome and the prognostic variables was analyzed using logistic regression mod...
PURPOSE As patients with mediastinal lymphoma are typically young with curable disease, advanced radiation techniques such as proton therapy are often considered to minimize subacute and late toxicity. However, it is unclear which mediastinal lymphoma patients are treated with proton therapy. Within a prospective, multi-institutional proton registry, we characterized mediastinal lymphoma patients treated with proton therapy and assessed concordance with consensus recommendations published in 201...

Abstract Background Capsular contracture causes pain, poor cosmesis, and reoperations. This study analyzes its incidence and risk factors in a more modern treatment era. Methods Patients undergoing mastectomy with implant reconstruction from 2010 to 18 were reviewed. Univariate and multivariate analysis evaluated rates and risk factors for capsular contracture. Results Among 451 patients, the majority underwent nipple-sparing mastectomy (262, 58.1%) with one-stage reconstruction (283, 62.7%) uti...

Study conducted to determine frequency and timing of unplanned breast implant removal after mastectomy, reconstruction, and postmastectomy radiation (PMRT). From 2010-2017, 52 patients underwent mastectomy, reconstruction, and PMRT. With median follow-up of 3.1 years, 23 patients (44%) experienced implant removal. Implant removal occurred in 9 (17%) patients before starting PMRT and 14 (27%) patients after starting PMRT. Implant removal rates were similar for hypofractionated PMRT compared with ...

Abstract Purpose We proposed a novel tool of dose-linear-energy-transfer (LET) volume histogram (DLVH) and performed an exploratory study to investigate rectal bleeding in prostate cancer treated by intensity-modulated proton therapy (IMPT). Methods DLVH was constructed with dose and LET as two axes, while the normalized volume of the structure was contoured in the dose-LET plane as iso-volume lines. We defined DLVH index, DL v % ( d , l ), i.e., v % of the structure have a dose of ≥ d Gy and an...

Abstract Purpose Data comparing moderately hypofractionated intensity-modulated radiation therapy (IMRT) and proton beam therapy (PBT) are lacking. We aim to compare late toxicity profiles of patients with early stage prostate cancer treated with moderately hypofractionated PBT and IMRT. Materials and Methods This multi-institutional analysis included patients with low- or intermediate-risk biopsy-proven prostate adenocarcinoma from 7 tertiary referral centers treated from 1998 to 2018. All pati...
