Brain Metastasis Incidence and Patterns of Presentation After Definitive Treatment of Locally Advanced Non-Small Cell Lung Cancer: A Potential Argument for Brain Magnetic Resonance Imaging Surveillance.

Purpose: Brain metastases (BMs) are a common source of morbidity and mortality. Guidelines do not advise brain surveillance for locally advanced non-small cell lung cancer (LA-NSCLC). We describe the incidence, time to development, presentation, and management of BMs after definitive chemoradiotherapy (CRT).

Five-year survivors from brain metastases treated with stereotactic radiosurgery: Biology, improving treatments, or just plain luck?

Background: Improvements in therapies have led to an increasing number of long-term survivors of brain metastases. The present series compares a population of 5-year survivors of brain metastases to a generalized brain metastases population to assess for factors attributable to long-term survival.

Methods: A single institution retrospective review was performed to identify 5-year survivors of brain metastases who received stereotactic radiosurgery (SRS).

Upstage Rate of Complex Sclerosing Lesions/Radial Scars.

Background: Radial scars (RS) and complex sclerosing lesions (CSL) are breast radiologic findings described as small, stellate lesions causing architectural distortion. This can mimic malignancy. Core needle biopsy (CNB) is often performed.

Evaluation of the Axillary Surgery Performed in Clinically Node-Positive Breast Cancer Patients Following Neoadjuvant Chemotherapy.

Background: The American College of Surgeons Oncology Group Z1071 trial in 2013 demonstrated the fesability of sentinel lymph node biopsy in clinically node-positive patients following neoadjuvant chemotherapy. The goal of this study was to determine the continued impact of this study on our practice pattern.

Materials And Methods: This is a retrospective review of institutional changes in the management of axillary nodal disease following the publication of Z1071.

Metabolic Response of Triple-Negative Breast Cancer to Folate Restriction.

Background: Triple-negative breast cancers (TNBCs), accounting for approximately 15% of breast cancers, lack targeted therapy. A hallmark of cancer is metabolic reprogramming, with one-carbon metabolism essential to many processes altered in tumor cells, including nucleotide biosynthesis and antioxidant defenses. We reported that folate deficiency via folic acid (FA) withdrawal in several TNBC cell lines results in heterogenous effects on cell growth, metabolic reprogramming, and mitochondrial impairment.

Dietary Energy Modulation and Autophagy: Exploiting Metabolic Vulnerabilities to Starve Cancer.

Cancer cells experience unique and dynamic shifts in their metabolic function in order to survive, proliferate, and evade growth inhibition in the resource-scarce tumor microenvironment. Therefore, identification of pharmacological agents with potential to reprogram cancer cell metabolism may improve clinical outcomes in cancer therapy. Cancer cells also often exhibit an increased dependence on the process known as autophagy, both for baseline survival and as a response to stressors such as chemotherapy or a decline in nutrient availability.
