Intentional wedge resection versus segmentectomy for ≤2 cm ground-glass-opacity-dominant non-small cell lung cancer: a real-world study using inverse probability of treatment weighting.

Background: Whether wedge resection is oncological suitable for ground glass opacity (GGO)-dominant non-small cell lung cancer (NSCLC) ≤2 cm is still debatable. The aim of this study is to investigate the short-term and long-term outcomes of intentional wedge resection and segmentectomy for those patients.

Materials And Methods: This was a real-world study from one of the largest thoracic surgery centers in West China.

Optimum timing of lung resection surgery following SARS-CoV-2 infection for non-small cell lung cancer.

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on postoperative recovery of non-small cell lung cancer (NSCLC) is need to be understood, thereby informing the optimal timing of surgical decision-making during the COVID-19 pandemic for NSCLC patients. This study reports the postoperative outcomes of surgical NSCLC patients with preoperative SARS-CoV-2 infection.

Method: This single-center retrospective cohort study included 241 NSCLC patients who underwent lobectomy or sub-lobectomy between December 1, 2022 and February 14, 2023.

The accuracy of Raman spectroscopy in the diagnosis of lung cancer: a systematic review and meta-analysis.

Background: To investigate the overall performance of Raman Spectroscopy (RS) in the diagnosis of lung cancer.

Methods: We systematic searched databases including PubMed, EMBASE, CNKI and Web of science for studies up to May 2020 with no start date limited. Then we extracted data of true positives, true negatives, false positives and false negatives from the included studies to calculate the pooled sensitivity, specificity, accuracy, positive and negative likelihood ratios (LRs), and diagnostic odds ratio (DOR), with 95% confidence intervals to evaluate the diagnostic value of Raman spectroscopy.

Clinicopathological features and prognostic analysis of metastatic pulmonary sarcomatoid carcinoma: a SEER analysis.

Background: Pulmonary sarcomatoid carcinoma (PSC) is a rare type of non-small cell lung cancer (NSCLC). Metastases are often detected at the first diagnosis. Despite high rates of distant metastasis, there is insufficient data describing the characteristics of PSC metastasis.
