A 63-year-old woman underwent right upper lobectomy for small cell carcinoma. She received a total of 2 courses of carboplatin and etoposide infusion as adjuvant therapy. One year after the operation, because of elevated serum Pro GRP levels and a metastatic brain tumor revealed by CT, 4 courses of IP therapy (irinotecan 60 mg/m(2), day 1, 8, 15 and cisplatin 60 mg/m(2), day 1, every 4 weeks) and whole brain radiotherapy (2 Gy f, 5 f/week, total 40 Gy) were given. A complete response was obtained, but a tumor relapse occurred ten months after the last chemotherapy. We then performed a stereotactic radiosurgery (marginal dose: 22 Gy, maximum dose 44 Gy), and one month later MRI showed the tumor had shrunk markedly. FDG-PET showed no intensive uptake, suggesting that there was no remaining viable tumor. No severe side effects were observed during these treatments. Currently, the patient has been alive with good performance status and no signs of relapse.

Osimertinib, a third-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), has revolutionized one of the standard most efficient treatments for EGFR mutation-positive non-small cell lung cancer (NSCLC). Osimertinib, a third-generation EGFR-TKI, is currently one of most efficient treatments in clinical practice. However, it has a potentially fatal side effect: interstitial lung disease (ILD).

Department of Oncology, Shandong Provincial Hospital Affiliated to Shandong First Medical University, P.R. China.
Background: Cryoablation induces antitumor immune responses. Spatial transcriptomic landscape technology has been used to determine the micron-level panoramic transcriptomics of tissue slices in situ.
Methods: The effects of cryoablation on the immune microenvironment in non-small cell lung cancer (NSCLC) were explored by comparing the Whole Transcriptome Atlas (WTA) panel of immune cells before and after cryoablation using the spatial transcriptomic landscape.
Comparison between lymph and non-lymph node resection in patients with stage IA non-small-cell lung cancer: A retrospective study.
J Cancer Res Ther

No. 2 Department of Thoracic Surgery, The Third Affiliated Hospital of Kunming Medical University, Kunming, China.
Objective: This retrospective study aimed to determine the need for lymph node resection during surgical treatment in patients with stage IA non-small-cell lung cancer (NSCLC).
Materials And Methods: A total of 1428 patients diagnosed with cT1N0M0 1 A stage NSCLC who underwent surgery were divided into two groups: lymphadenectomy (n = 1324) and nonlymphadenectomy (n = 104). The effects of lymph node resection on overall survival (OS) and recurrence-free survival (RFS) and on clinicopathological factors that affected the prognosis of the patients were investigated.
High-Cost Cancer Drug Use in Medicare Advantage and Traditional Medicare.
JAMA Health Forum

Department of Health Systems, Management, and Policy, University of Colorado Cancer Center, Aurora.
Importance: Medicare Advantage (MA) plans are designed to incentivize the use of less expensive drugs through capitated payments, formulary control, and preauthorizations for certain drugs. These conditions may reduce spending on high-cost therapies for conditions such as cancer, a condition that is among the most expensive to treat.
Objective: To determine whether patients insured by MA plans receive less high-cost drugs than those insured by traditional Medicare (TM).
FABP5 regulates ROS-NLRP3 inflammasome in glutamate-induced retinal excitotoxic glaucomatous model.

Fatty acid binding proteins (FABPs) are a class of small molecular mass intracellular lipid chaperone proteins that bind to hydrophobic ligands, such as long-chain fatty acids. FABP5 expression was significantly upregulated in the N-methyl-d-aspartic acid (NMDA) model, the microbead-induced chronic glaucoma model, and the DBA/2J mice. Previous studies have demonstrated that FABP5 can mediate mitochondrial dysfunction and oxidative stress in ischemic neurons, but the role of FABP5 in oxidative stress and cell death in retina NMDA injury models is unclear.
