AI Article Synopsis
Article Abstract
Background: The National Lung Screening Trial (NLST) established a role for lung cancer screening. Mortality benefits with screening are predicated on successful treatment with low surgical mortality. Given variations observed in perioperative outcomes after lung cancer resection, it remains unknown whether benefits observed in the NLST are generalizable to a broader population. We sought to determine whether NLST perioperative outcomes are reflective of contemporary practice in a national cohort.
Methods: We identified patients diagnosed with non-small cell lung cancer who underwent lung resection in the 2014 to 2015 National Cancer Database (NCDB) and the NLST. We compared demographic and cancer characteristics in both datasets. We used hierarchical logistic regression to compare 30-day and 90-day postoperative mortality across facilities in both datasets.
Results: In all, 65054 patients in NCDB and 1003 patients in the NLST treated across 1119 NCDB hospitals and 33 NLST hospitals were included. After risk and reliability adjustment, mean 30-day and 90-day mortality were significantly higher among NCDB hospitals (mean 30-day, 2.2 [95% confidence interval (CI), 2.2 to 2.2] vs 1.8 [95% CI, 1.8 to 1.8], P < .001; mean 90-day, 4.2 [95% CI, 4.2 to 4.3] vs 2.9 [95% CI, 2.9 to 2.9], P < .001). Variation in risk- and reliability-adjusted 30-day mortality (95% CI, 1.1% to 4.9%) and 90-day mortality (95% CI, 2.6% to 9.7%) was observed among NCDB hospitals. Adjusted mortality was similar among NLST facilities (30 days, 1.8% to 1.8%; 90 days, 2.9% to 2.9%).
Conclusions: Risk- and reliability-adjusted postoperative mortality varies widely in a national cohort compared with outcomes observed in the NLST. Efforts to minimize this variation are needed to ensure that benefits of lung cancer screening are fully realized in the United States.

Aim: The prognostic factors and a nomogram applicable to breast cancer (BC) patients with bone metastasis (BM) who received first-line chemotherapy have not been extensively studied. This study aimed to identify prognostic factors and construct a prognostic nomogram to predict overall survival (OS) in this population.
Methods: Data for BC patients with BM undergoing first-line chemotherapy were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2016.

The incidence of lung cancer is the highest among all tumors, and treatment has become an urgent problem to be solved. The Drug-eluting bead-based bronchial arterial chemoembolization (DEB-BACE) combination immunotherapy is a rare neoadjuvant therapy for lung cancer surgery, which can significantly reduce the time it takes for lung cancer patients to undergo surgery.We report a male patient, aged 59-year-old, with Stage-III b squamous cell lung cancer accompanied by hemoptysis underwent surgical resection after DEB-BACE combination immunotherapy treatment 21 days later without obvious adverse events.

Thoracic SMARCA4-deficient undifferentiated tumors (SMARCA4-UTs), recently recognized as a rare malignancy described in the 5th edition of the World Health Organization Classification of Tumors, are characterized by an inactivating mutation in SMARCA4, most commonly found in the mediastinum of male smokers. Despite the aggressive nature and poor prognosis associated with these tumors, which have a median survival time of approximately 4-7 months, no standardized treatment guidelines are currently established. There are currently no reported cases of extended progression-free survival (PFS) in SMARCA4-UT patients treated with surgery and immunotherapy.

There are many causes of peripheral blood eosinophilia (PBE), including allergic, infectious, rheumatic, and hematologic disorders. Solid tumor cancers, such as lung cancer, can also cause PBE, and although rare, being diagnosed with PBE in this way is associated with a worse prognosis than for lung cancer patients without PBE. Additionally, some cancer patients develop PBE when receiving treatment with immune checkpoint inhibitors (ICIs).
