Aim: To evaluate the CD8+CD28- and CD4+CD25+ regulatory T (Treg) cells in addition to other some lymphocyte subgroups in peripheral blood of advanced stage lung cancer patients.
Methods: The study group (n = 28) comprised chemotherapy and radiotherapy naïve patients with non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). The control group (n = 22) consisted of age- and sex-matched healthy volunteers. Flow cytometry was used to count T cells, natural killer (NK) cells and CD4+CD25 Treg cells, and for CD8+ T cell subgroup analysis. Flow cytometry was performed and annexin V binding was used for apoptotic cell evaluation.
Results: In patient group, the percentage of CD8+CD28- cells among lymphocytes was elevated, and there was also an increase in the CD28-/CD28+ cell ratio among CD8 lymphocyte population. The distribution of CD8 cells was different in lung cancer patients when compared with the control group. The absolute count of CD4+CD25(bright) cells and the percentages of these cells among total lymphocytes were higher in the patient group. The Annexin V(+) cell percentages among CD8+CD28- and CD8+CD28+ lymphocytes were higher in the patient group than in the control group. No differences were found between the NSCLC and SCLC patients with respect to the hematological parameters and the distribution of lymphocyte subgroups. In NSCLC patients, the percentage of CD8+CD28- cells among the lymphocyte population was higher in patients with stage IV than those with stage III.
Conclusion: These findings may reflect the possibility of tumor-induced immunosuppression and they should be complemented with further studies.

Objective: The aim of this study is to explore the clinicopathological features, radiographic manifestations, treatment options, and prognosis of primary pulmonary angiosarcoma (PPAS).
Method: We summarized and analyzed the clinical data of 11 patients with primary pulmonary angiosarcoma treated at the First Affiliated Hospital of Guangzhou Medical University between January 2018 and January 2024. A retrospective analysis was conducted in conjunction with a review of the relevant literature.
EGFR status assessment using reflex testing targeted next-generation sequencing for resected non-squamous non-small cell lung cancer.

EGFR status assessment is mandatory for adjuvant decision-making of resected stage IB-IIIA non-squamous non-small cell lung cancer (NS-NSCLC). It is questionable whether single-gene RT-PCR versus next-generation sequencing (NGS) should be used for this evaluation. Moreover, co-occurring mutations have an impact on tumor behavior and may influence future therapeutic decision-making.

Third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is the standard therapy for patients harboring T790M after first-generation EGFR-TKI resistance. However, the impact of acquired EGFR amplification on the efficacy of third-generation EGFR-TKI against T790M remains uncertain. We aimed to investigate whether the presence of acquired EGFR amplification after first-generation EGFR-TKI resistance influences the efficacy of third-generation EGFR-TKI in patients with advanced non-small-cell lung cancer (NSCLC).
