The anti-PD1 monoclonal antibody pembrolizumab improves survival in recurrent/metastatic head and neck squamous cell carcinoma (HNSCC). Patients with locoregional, pathologically high-risk HNSCC recur frequently despite adjuvant cisplatin-radiation therapy (CRT). Targeting PD1 may reverse immunosuppression induced by HNSCC and CRT.

In this prospective, dual-center, phase 2 study, we investigated the efficacy and tolerability of reduced elective nodal volume and dose in oropharyngeal and laryngeal squamous cell carcinoma.
Methods And Materials: Patients with newly diagnosed squamous cell carcinoma of the oropharynx and larynx were eligible for enrollment.
Purpose: The size and growth of U.S. radiation oncology (RO) residency positions have important implications for the RO workforce.
View Article and Find Full Text PDFBackground: The role of chemotherapy in extremity/trunk soft-tissue sarcoma (ET-STS) is controversial, even for patients at high risk for distant recurrence and death (those with high-grade tumors ≥5 cm in size). This study examines the impact of integrating chemotherapy with neoadjuvant radiotherapy (RT) on overall survival (OS) for patients with high-risk ET-STS.
Methods: The National Cancer Data Base was queried for adult patients with high-risk ET-STS who received neoadjuvant RT and limb salvage surgery between 2006 and 2014.
Purpose: Palbociclib is a selective cyclin-dependent kinase 4/6 inhibitor approved for metastatic ER+/HER2- breast cancer. Preclinical evidence suggests a possible synergistic effect of palbociclib when combined with radiation therapy (RT); however, the toxicity of this pairing is unknown. We report preliminary results on the use of this combination.

The heterogeneity in presentation and diagnosis within a patient population with HPV-positive OPSCC and its impact on times to presentation, diagnosis, and treatment have yet to be characterized.
Participants: Patients with biopsy-proven p16-positive OPSCC seen and/or treated at our institution between 2008 and 2018.

Purpose: To examine the role of radiation oncology (RO) graduates' application patterns and personal preferences in current labor concerns.
Methods And Materials: An anonymous, voluntary survey was distributed to 665 domestic RO graduates from 2013 to 2017. Questions assessed graduates' regional (Northeast [NE]; Midwest [MW]; South [SO]; West [WT]) job type and population size preferences.
Objective: To evaluate outcomes and survival in young patients with oral tongue cancer (OTC).
Methods: Retrospective chart review of patients aged 18-40 with OTC treated between 2000 and 2016. Tumor characteristics of p16 expression, perineural invasion (PNI), and lymph-vascular invasion (LVI) were evaluated.
Objectives: Patients with large, high-grade extremity soft tissue sarcoma (STS) are at high risk for both local and distant recurrence. RTOG 95-14, using a regimen of neoadjuvant interdigitated chemoradiotherapy with mesna, doxorubicin, ifosfamide, and dacarbazine followed by surgery and 3 cycles of adjuvant mesna, doxorubicin, ifosfamide, and dacarbazine, demonstrated high rates of disease control at the cost of significant toxicity (83% grade 4, 5% grade 5). As such, this regimen has not been widely adopted.

Purpose: To examine whether permanent radiation oncologist (RO) employment opportunities vary based on geography.
Methods And Materials: A database of full-time RO jobs was created by use of American Society for Radiation Oncology (ASTRO) Career Center website posts between March 28, 2016, and March 31, 2017. Jobs were first classified by region based on US Census Bureau data.
Objective: Stereotactic body radiotherapy (SBRT) for early-stage non-small-cell lung cancer (NSCLC) is the standard of care in medically inoperable patients. In very elderly patients, previous studies have shown SBRT to offer excellent local control, though with higher toxicities than in younger populations. We report our institutional experience using SBRT in the definitive management of NSCLC in patients ≥80years old.

The Varian Truebeam STx (Varian Medical Systems, Palo Alto, CA) linear accelerator (LINAC) system is an arc-based, frameless stereotactic radiosurgery system used for the treatment of TN. To our knowledge, there has been only one published series of patient histories that documents the use of a frameless LINAC system for the treatment of TN.
View Article and Find Full Text PDFSoft tissue sarcomas (STS) consist of a heterogeneous group of rare malignancies arising from mesenchymal origin. While surgical resection is the primary treatment for STS, the use of radiotherapy (RT) as an adjunctive modality has been shown to improve oncologic outcomes. Technologic improvements, such as image guidance and intensity-modulated radiotherapy that significantly improve both the precision and delivery of RT, have led to the reduction of long-term RT toxicities without compromising outcomes.
View Article and Find Full Text PDFIntroduction: The benefit of surgery (trimodality therapy [TMT]) after chemoradiotherapy (CRT) for patients with stage III non-small-cell lung cancer (NSCLC) is controversial, but nodal pathologic complete response (N-PCR) is accepted as a strong predictor of overall survival (OS). We compared the outcomes of patients treated with TMT versus CRT, focusing on the importance of N-PCR.
Methods: Patients with stage III NSCLC treated with CRT or TMT from December 2004 through December 2012 were included; patients with N3 disease were excluded.
Background: The purpose of this study was to report long-term outcomes for a large cohort of patients with head and neck squamous cell carcinoma (HNSCC) who underwent stereotactic body radiotherapy (SBRT) reirradiation.
Methods: From 2002 to 2011, 85 patients with previously irradiated HNSCC were treated with SBRT to 94 lesions. Some underwent surgery (29%), and many were treated with induction, concurrent, and/or adjuvant chemotherapy or biologic therapy (70%).
