[Impact of the Size and Depth of Pulmonary Nodules on the Surgical Approach for Lung Resection in the Treatment of Early-stage Lung Cancer ≤2 cm].

Background: Current studies suggest that for early-stage lung cancers with a component of ground-glass opacity measuring ≤2 cm, sublobar resection is suitable if it ensures adequate margins. However, lobectomy may be necessary for some cases to achieve this. The aim of this study was to explore the impact of size and depth on surgical techniques for wedge resection, segmentectomy, and lobectomy in early-stage lung cancer ≤2 cm, and to determine methods for ensuring a safe resection margin during sublobar resections.

[Influencing Factors and Significance of Tumor-associated Macrophage Polarization in Tumor Microenvironment].

Tumor-associated macrophages (TAMs), characterized by high plasticity, are the most abundant immune cells in the tumor microenvironment (TME). TAMs are recruited to tumor region in response to various TME components such as cytokines, chemokines as well as exosomes. Subsequently, these environmental cues induce a certain polarization state of TAMs, ranging from anti-tumor states (M1-like) to pro-tumor states (M2-like).
