Virtual interviews and equity: The pediatric pulmonary fellow perspective.

Background And Objectives: The SARS-CoV-2 pandemic shifted medical training programs to utilize virtual interviews (VIs) starting with the 2020 interview cycle. Fellowship interviews continue in the virtual format. It is unknown how this shift has affected equity for applicants as compared to in-person interviews.

Identification of an optimal mutant allele frequency to detect activating , , and mutations in a commercial cell-free DNA next-generation sequencing assay in colorectal and pancreatic adenocarcinomas.

Background: Evaluation for activating mutations in , , and in colorectal cancer (CRC) and in in pancreatic ductal adenocarcinoma (PDAC) is essential for clinical care. Plasma cell-free DNA (cfDNA) next-generation sequencing (NGS) allows convenient assessment of a tumor's molecular profile, however low tumor DNA shedding limits sensitivity. We investigated mutant allele frequency (MAF) of other oncogenic dominant genes to identify a threshold for accurate detection of and mutations in cfDNA.

Long-term risk of carotid stenosis and cerebrovascular disease after radiation therapy for head and neck cancer.

Background: Recipients of radiation therapy (RT) for head and neck cancer (HNC) are at significantly increased risk for carotid artery stenosis (CAS) and cerebrovascular disease (CVD). We sought to determine (1) cumulative incidences of CAS and CVD among HNC survivors after RT and (2) whether CAS is associated with a RT dose response effect.

Methods: This single-institution retrospective cohort study examined patients with nonmetastatic HNC who completed (chemo)RT from January 2000 through October 2020 and subsequently received carotid imaging surveillance ≤2 years following RT completion and, in the absence of CAS, every 3 years thereafter.

Pan-Cancer Proteomics Analysis to Identify Tumor-Enriched and Highly Expressed Cell Surface Antigens as Potential Targets for Cancer Therapeutics.

The National Cancer Institute's Clinical Proteomic Tumor Analysis Consortium (CPTAC) provides unique opportunities for cancer target discovery using protein expression. Proteomics data from CPTAC tumor types have been primarily generated using a multiplex tandem mass tag (TMT) approach, which is designed to provide protein quantification relative to reference samples. However, relative protein expression data are suboptimal for prioritization of targets within a tissue type, which requires additional reprocessing of the original proteomics data to derive absolute quantitation estimation.

Adaptive Positron Emission Tomography Radiation Therapy in Patients With Locally Advanced Vulvar Cancer: A Prospective Study.

Purpose: In this prospective trial, we aim to determine whether fluorodeoxyglucose positron emission tomography and computed tomography (PET/CT)-based adaptive radiation therapy (ART) improves dosimetry outcomes for patients treated with definitive radiation for locally advanced vulvar cancer.

Methods And Materials: Patients were enrolled in 2 sequential institutional review board-approved prospective protocols for PET/CT ART from 2012 to 2020. Patients were planned with pretreatment PET/CT to 45 to 56 Gy in 1.

Divergent Interpretations of Imaging After Stereotactic Body Radiation Therapy for Lung Cancer.

Purpose: Conflicting information from health care providers contributes to anxiety among cancer patients. The purpose of this study was to investigate discordant interpretations of follow-up imaging studies after lung stereotactic body radiation therapy (SBRT) between radiologists and radiation oncologists.

Methods And Materials: Patients treated with SBRT for stage I non-small cell lung cancer from 2007 to 2018 at Duke University Medical Center were included.
