Background: Previous studies have demonstrated that survival of patients with non-small cell lung cancer (NSCLC) with oligometastasis may benefit from local treatment. The purpose of this study was to compare the efficacy of local surgical treatment with systematic chemoradiotherapy in NSCLC with oligometastasis.
Methods: Data from a total of 172 patients with NSCLC with oligometastasis were collected at our Cancer Hospital from January 2006 to December 2016. The patients were divided into two groups: group A (82 cases) underwent primary surgical treatment and adjuvant chemotherapy was performed after operation, while group B (90 cases) received systematic chemotherapy and local radiotherapy. The median survival time (MST) and the 5-year survival rate of the two groups were compared and analyzed. The effects of various pathological types, surgical methods of the primary tumors and the site of oligometastasis were also analyzed.
Results: The MSTs in groups A and group B were 48 months and 18 months, respectively, and the 5-year survival rates were 21.1% and 7.6%, respectively (P<0.05). In group A, the survival rates were higher in patients with adrenal metastasis than patients with metastasis in the brain, bone, the liver or in other oligometastatic patients (P<0.05). There was no significant difference in the survival rate among the various pathological types or surgical methods of primary tumors (P>0.05).
Conclusions: Local surgical treatment of primary lesions in NSCLC significantly prolonged overall survival and 5-year survival rates of patients with NSCLC with oligometastasis.

Erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), is currently used in the therapy of several solid malignancies. This agent has been associated with several dermatological side-effects, the most common being papulo-pustular acneiform rash. Herein we describe a unique skin effect in a patient treated with erlotinib for non-small cell lung cancer.

Resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) is the main cause of mortality in lung cancer. This study aimed to investigate the roles of neuropilin 1 (NRP1) in non-small cell lung cancer (NSCLC). NRP1 expression was assessed in tumor tissues from patients with osimertinib-resistant (OR) NSCLC and osimertinib-responsive NSCLC as well as in patients with paracancerous NSCLC tissues who did not undergo radiotherapy or chemotherapy.

This study aimed to explore the risk factors for mediastinal lymph node metastases (MLNM) in patients with early-stage non-small-cell lung cancer (NSCLC) and to establish a predictive model. A retrospective analysis was conducted on the clinical data from NSCLC patients treated at the Second Affiliated Hospital of Guangzhou Medical University and the First Affiliated Dongguan Hospital of Guangdong Medical University between March 2021 and March 2023. Baseline clinical data, laboratory parameters, and pathological features were collected and analyzed.

Background: Immune checkpoint inhibitors (ICIs) have emerged as the first-line treatment for driver-negative advanced non-small cell lung cancer (NSCLC). However, there is uncertainty regarding the availability and timing of ICI initiation in patients with NSCLC combined with pulmonary tuberculosis (TB). Additionally, the implementation of dual therapy for anti-TB and anti-tumor treatment poses significant challenges in terms of avoiding drug-drug interactions and reducing adverse reactions during clinical diagnosis and treatment.

Primary and secondary resistance to immune checkpoint blockade (ICB) reduces its efficacy. The mechanisms underlying immunotherapy resistance are highly complex. In non-small cell lung cancer (NSCLC), these mechanisms are primarily associated with the loss of programmed cell death-ligand 1 (PD-L1) expression, genetic mutations, circular RNA axis and transcription factor regulation, antigen presentation disorders, and dysregulation of signaling pathways.
