94, 3.03, and 2.03 years. Three-year actuarial OS for the entire group was 34.1% from second course of RT. The mean EQD2 Gy mean lung dose for all courses was 12.35 Gy (range, 2.7-26.52). The mean EQD2 Gy V5Gy, V10Gy, V20Gy, V30Gy, and V40Gy were 40.9%, 25.5%, 14.7%, 10.2%, and 7.7%. Six-year actuarial freedom from grade ≥3 complications was 86.3%. The rate of grade ≥3 lung toxicity was 4.5% (2 of 44). Other late toxicities included grade 3 recurrent laryngeal nerve damage (n = 1) and grade 3 chest wall pain/rib fracture (n = 1). Overall, 32% of patients had more than 2 courses of RT to the lung (range, 3-7). Long-term OS is possible with multiple RT courses to the lung for NSCLC with low toxicity. Long-term OS is possible with multiple RT courses to the lung for NSCLC with low toxicity. As a means of limiting normal tissue toxicity, proton-beam therapy (PBT) is an emerging radiation modality for glioblastoma (GBM) reirradiation. However, data for recurrent GBM treated with PBT reirradiation is limited. Therefore, we analyzed treatment patterns, toxicities, and clinical outcomes of patients with recurrent GBM treated with PBT reirradiation using the multi-institutional Proton Collaborative Group registry. Prospectively collected data for patients with recurrent GBM who underwent PBT while enrolled in Proton Collaborative Group study 01-009 (NCT01255748) were analyzed. We evaluated overall survival (OS), progression-free survival (PFS), and toxicity. Toxicities were scored per the Common Terminology Criteria for Adverse Events, version 4.0. Descriptive statistics were used to report patient, tumor, and treatment characteristics. Multivariable analyses (MVA) for toxicity were conducted using logistic regression. The Kaplan-Meier method was used to calculate OS and PFS. MVA for OS and PFS wa rates comparable with previously reported photon reirradiation. This is the largest series to date reporting outcomes for PBT reirradiation of patients with recurrent GBM. Our analysis indicates that PBT is well tolerated and offers efficacy rates comparable with previously reported photon reirradiation. Reirradiation (re-RT) using external beam radiation therapy (EBRT) is a novel salvage strategy for local failure in prostate cancer. We performed a systematic review describing oncologic and toxicity outcomes for salvage EBRT/stereotactic radiation therapy (SBRT) re-RT. A International ProspectiveRegisterof Systematic Reviews registered (#141466) systematic review, meta-analysis, and meta-regression was conducted using preferred reporting items for systematic reviews and meta-analyses guidelines. PubMed and EMBASE were searched from inception through September 2019. Outcome measures included local control (LC), biochemical relapse free survival (BRFS), and ≥grade 3 genitourinary (GU)/gastrointestinal (GI) toxicity. EBRT and SBRT data were collected separately. Meta-regression explored disease and toxicity outcomes as a function of equivalent dose in 2 Gy fractions (EQD2), length of follow-up, and partial versus whole prostate reirradiation. Nineteen studies representing 13 cohorts were included (428 pattherapy use in the primary literature. Further prospective studies and longer follow-up are needed before considering re-RT as standard practice. Salvage re-RT using EBRT, particularly with SBRT, is an emerging technique to treat isolated local failure of prostate cancer. With short-term follow-up, LC, BRFS, and reported toxicities appear reasonable, although further follow-up is required before definitive statements on late toxicities can be made. Our review is limited by incomplete reporting of androgen deprivation therapy use in the primary literature. Further prospective studies and longer follow-up are needed before considering re-RT as standard practice. There is no standard of care for recurrent high-grade glioma. Treatment strategies include reresection, reirradiation, systemic agents, intratumoral thermotherapy using magnetic iron-oxide nanoparticles ("nanotherapy"), and tumor treating fields. Only a small number of patients are eligible for reresection, and because many patients receive a full course of radiation therapy, there is fear of reirradiation-induced morbidity. Modern radiation techniques have resulted in greater acceptance of reirradiation. In this work we retrospectively analyzed patients who had undergone reirradiation of high-grade glioma at Charité Universitätsmedizin Berlin. All patients treated with reirradiation for recurrent high-grade glioma in our department from January 1997 to February 2014 were analyzed in this study. In total, 198 patients were included. The primary endpoint was overall survival after recurrence. One hundred ninety-eight patients were identified. Median time from first radiation therapy to reirradiation was gher doses (eg, 49.4 Gy/3.8 Gy) in selected patients. The prognosis of recurrent high-grade glioma remains dismal. Reirradiation is often tolerable even after early recurrence ( less then 14 months) and with higher doses (eg, 49.4 Gy/3.8 Gy) in selected patients. To evaluate the safety and efficacy of definitive chemoradiotherapy (CRT) for patients with clinical T1N0M0 esophageal adenocarcinoma. This was a retrospective study of patients with clinical T1N0 adenocarcinoma of the esophagus treated with curative-intent CRT between 2004 and 2017 at 2 tertiary care centers. https://www.selleckchem.com/ Patients received CRT instead of esophagectomy owing to medical comorbidities or patient preference. Toxicities were evaluated according to Common Terminology Criteria for Adverse Events version 4.03. The Kaplan-Meier method was used to estimate overall, progression-free, and disease-specific survivals. Twenty-eight patients were included for analysis. Median age was 76 years (range 55-90). The majority of patients were male (93%) and had a history of Barrett's esophagus (71%). Tumor characteristics included distal esophagus location (93%), clinical stage T1b (86%), and median length of 2 cm (range, 1-9). Prior endoscopic resection was performed in 57%.The median follow-up was 44 months (range, 4-146).
