Characterizing Opioid Prescribing Trends of Medical Oncologists From 2013 to 2019: Analysis From the Centers for Medicare & Medicaid Services Medicare Part D Prescribers Database.

Purpose: Opioid prescribing trends in medical oncology are poorly defined past 2017, the year after the CDC updated opioid prescription guidelines in noncancer settings. We aim to characterize pain management by medical oncologists by analyzing opioid and gabapentin prescribing trends from 2013 to 2019, identify physician-related factors associated with prescribing patterns, and assess whether CDC guidelines for nononcologic settings changed prescribing patterns.

Methods: The Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescribers-by Provider, CMS Medicare Part D Prescribers-by Provider and Drug, and CMS Medicare Physician National Downloadable files from 2013 to 2019 were merged by National Provider Identification.

Treatment of ALK-rearranged non-small-cell lung cancer with brigatinib as second or later lines: real-world observations from a single institution.

The second-generation ALK tyrosine kinase inhibitor brigatinib has recently been approved in the European Union for use after crizotinib treatment in patients with EML4-ALK-rearranged lung cancer. In the current study, brigatinib was investigated as second-line or later-line treatment in 35 patients who had developed resistance to crizotinib, ceritinib, or alectinib. Most patients (68.

Comparison of RECIST, iRECIST, and PERCIST for the Evaluation of Response to PD-1/PD-L1 Blockade Therapy in Patients With Non-Small Cell Lung Cancer.

Purpose: The aim of this study was to compare the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, the immune RECIST (iRECIST) criteria, and the Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) 1.0 in patients with advanced non-small cell lung cancer treated with programmed cell death protein 1 (PD-1)/programmed cell death protein 1 ligand (PD-L1) inhibitors.

EGFR Mutations in Cell-free Plasma DNA from Patients with Advanced Lung Adenocarcinoma: Improved Detection by Droplet Digital PCR.

Background: Analysis of cell-free DNA from blood could provide an alternative method for identifying genomic changes in the tumors of patients with advanced lung adenocarcinoma.

Objective: We compared the performance of droplet digital PCR (ddPCR) and Cobas EGFR Mutation Test v2 (Cobas) for detecting EGFR mutations in cell-free plasma DNA.

Patients And Methods: Plasma samples from patients with advanced EGFR-mutated lung adenocarcinoma were analyzed for EGFR T790M, exon 19 deletions, and L858R mutations by both ddPCR and Cobas.

Liquid-Biopsy-Based Identification of EGFR T790M Mutation-Mediated Resistance to Afatinib Treatment in Patients with Advanced EGFR Mutation-Positive NSCLC, and Subsequent Response to Osimertinib.

Background: Acquired epidermal growth factor receptor (EGFR) T790M mutation is the primary resistance mechanism to first-generation EGFR tyrosine kinase inhibitors (TKIs) used in advanced, EGFR mutation-positive non-small-cell lung cancer (NSCLC). Available data, predominantly in Asian patients, suggest that this mutation is also the major cause of resistance to the irreversible ErbB family blocker, afatinib. For EGFR T790M-positive patients who progress on EGFR TKI therapy, osimertinib is an effective treatment option.

Cell-Free Plasma DNA-Guided Treatment With Osimertinib in Patients With Advanced EGFR-Mutated NSCLC.

Introduction: Osimertinib is standard treatment for patients with advanced EGFR T790M-mutated non-small-cell lung cancer who have been pre-treated with EGFR-tyrosine kinase inhibitors (TKIs). We studied whether cell-free plasma DNA for T790M detection can be used to select patients for osimertinib treatment in the clinical routine.

Methods: From April 2015 to November 2016, we included 119 patients with advanced EGFR-mutated non-small-cell lung cancer who had progressed under treatment with an EGFR-TKI.

Symptomatic pseudo-progression followed by significant treatment response in two lung cancer patients treated with immunotherapy.

In the setting of pseudo-progression in a cancer patient who receives immunotherapeutic treatment, discontinuation of therapy is recommended if the patient is symptomatic. Here, we present two patients with advanced adenocarcinoma of the lung who developed massive tumor growth after initiation of treatment with the anti-PD-1 antibody pembrolizumab. Even though clinical deterioration occurred in the form of severe dyspnea and weight loss, pembrolizumab therapy was continued, as the speed of tumor growth suggested pseudo-progression and the tumors showed marked PD-L1 expression.

Complete remission of intrathecal metastases with lorlatinib therapy in a heavily pretreated ALK-positive lung cancer patient.

Patients with lung cancer who show EML4-ALK translocation are routinely treated with ALK tyrosine kinase inhibitors, although in the majority of cases, these patients develop resistance over time. The central nervous system is a common of site of recurrence in this population, which calls for next-generation drugs that can penetrate into the brain and achieve clinically meaningful central nervous system activity. Here, I report the case of a female patient diagnosed with adenocarcinoma of the lung in 2005, at the age of 46 years, who underwent lobectomy and then experienced a series of progression episodes 6 years later.

Hypothalamic insulin responsiveness is associated with pancreatic insulin secretion in humans.

Context: Activity of the hypothalamus - the major brain area controlling peripheral metabolism - is specifically modulated by insulin. Research in animals suggests that brain insulin action influences pancreatic insulin secretion.

Objective: We investigated the association between hypothalamic insulin sensitivity and pancreatic insulin secretion in humans.
