High risk lung nodule: A multidisciplinary approach to diagnosis and management.

Pulmonary nodules are often discovered incidentally during CT scans performed for other reasons. While the vast majority of nodules are benign, a small percentage may represent early-stage lung cancer with the potential for curative treatments. With the growing use of CT for both clinical purposes and lung cancer screening, the number of pulmonary nodules detected is expected to increase substantially.

A machine learning model for ranking candidate HLA class I neoantigens based on known neoepitopes from multiple human tumor types.

Tumor neoepitopes presented by major histocompatibility complex (MHC) class I are recognized by tumor-infiltrating lymphocytes (TIL) and are targeted by adoptive T-cell therapies. Identifying which mutant neoepitopes from tumor cells are capable of recognition by T cells can assist in the development of tumor-specific, cell-based therapies and can shed light on antitumor responses. Here, we generate a ranking algorithm for class I candidate neoepitopes by using next-generation sequencing data and a dataset of 185 neoepitopes that are recognized by HLA class I-restricted TIL from individuals with metastatic cancer.

Characteristics of Matriculants to Thoracic Surgery Residency Training Programs.

Background: Thoracic surgery (TS) residency positions are in high demand. There is no study describing the nationwide attributes of successful matriculants in this specialty. We examined the characteristics of TS resident applicants and identified factors associated with acceptance.

Incidence of Asymptomatic Brain Metastases in Metastatic Colorectal Cancer.

Background: Current literature suggests that brain metastasis is an infrequent occurrence in metastatic colorectal cancer. Outside of rare autopsy studies, these retrospective reports describe the incidence of symptomatic brain metastasis and therefore lack a description of the incidence in asymptomatic patients. With improved survival and a lack of routine brain imaging, the true incidence of brain metastasis among patients with metastatic colorectal cancer is likely under-recognized.

Adoptive T-Cell Therapy for Solid Malignancies.

The use of immunotherapies for solid and hematologic malignancies has demonstrated durable antitumor effects. Use of checkpoint inhibitors allows for immunologic reactivation of the adaptive immune system against tumor-specific neoantigens and effective rejection. Recent developments in adoptive transfer of T cells has shown effective immune rejection of solid malignancies and durable regression.

Surgeon, not disease severity, often determines the operation for acute complicated diverticulitis.

Background: The "best" operation in the setting of acute complicated diverticulitis has been debated for decades. Multiple studies, including a recent prospective randomized trial, have reported improved outcomes with primary anastomosis. The aim of this study was to determine whether surgeon or patient-specific factors drives the choice of operative procedure.
