<b><i>Background:</i></b> Sex-determining region Y-box 2 (SOX2) is a transcriptional factor that drives embryonic stem cells to neuroendocrine cells in lung development and is highly expressed in small-cell lung cancer (SCLC). However, the prognostic role of SOX2 and its relationship with tumor-infiltrating lymphocytes (TILs) has not been determined in SCLC. Herein, we assessed the expression of SOX2 and CD8+ TILs to obtain insights into the prognostic role of SOX2 and CD8+ TILs in limited-stage (LS)-SCLC. <b><i>Methods:</i></b> A total of 75 patients with LS-SCLC was enrolled. The SOX2 expression and CD8+ TILs were evaluated by immunohistochemistry. <b><i>Results:</i></b> High SOX2 and CD8+ TIL levels were identified in 52 (69.3%) and 40 (53.3%) patients, respectively. High SOX2 expression was correlated with increased density of CD8+ TILs (<i>p</i> = 0.041). Unlike SOX2, high CD8+ TIL numbers were associated with significantly longer progression-free survival (PFS; 13.9 vs. 8.0 months, <i>p</i> = 0.014). Patients with both high SOX2 expression and CD8+ TIL numbers (<i>n</i> = 29, 38.7%) had significantly longer PFS and overall survival (OS) compared to those from the other groups (median PFS 19.3 vs. 8.4 months; <i>p</i> = 0.002 and median OS 35.7 vs. 17.4 months; <i>p</i> = 0.004, respectively). Multivariate Cox regression analysis showed that the combination of high SOX2 expression and CD8+ TIL levels was an independent good prognostic factor for OS (HR = 0.471, 95% CI, 0.250–0.887, <i>p</i> = 0.02) and PFS (HR = 0.447, 95% CI, 0.250–0.801, <i>p</i> = 0.007) in SCLC. <b><i>Conclusions:</i></b> Evaluation of the combination of SOX2 and CD8+ TIL levels may be of a prognostic value in LS-SCLC.

Phagocytosis is a critical host defense mechanism used by macrophages and neutrophils to clear invading pathogens. The complex sequence of events resulting in internalization and degradation of the pathogens is a coordinated process involving lipids, signaling proteins, and the cytoskeleton. Here, we examine the role of the microtubule cytoskeleton in supporting both the engulfment of pathogens and their elimination within phagolysosomes.Key words: macrophage, microtubule, phagocytosis, maturation, Fc receptor.

Background/Aims: The role of Tumor-infiltrating lymphocytes (TILs) in the prognosis of patients with lung cancer is still controversial. We performed a meta-analysis to evaluate the prognostic role of TILs in lung cancer. Methods: Studies were recruited by searching PubMed, Embase and the Cochrane Library and assessed by further quality evaluation. The pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated to investigate the association between TIL subsets and lung cancer patients' outcome. Results: A total of 29 articles including 8,600 patients were enrolled into the meta-analysis. Our results indicated that high level of CD8+ cells infiltration in tumor stroma (TS) or tumor nest (TN) was associated with better OS in lung cancer patients (HR = 0.76, 95% CI 0.62-0.93, P = 0.006; HR = 0.80, 95% CI 0.67-0.96; P = 0.018, respectively). Similar results could be also observed in CD3+ T cells infiltration. High CD4+ T lymphocytes infiltration in TS was explicitly accompanied by better OS (HR = 0.65, 95% CI 0.46-0.91; P = 0.013), rather than in TN. In contrast, high density of FOXP3+ T cells infiltration in TS showed a poor PFS (HR = 2.67, 95% CI, 1.74-4.08, P < 0.001). Conclusion: This meta-analysis clarified that high level of CD8+ and CD3+ T cells infiltration in TS or TN, and high CD4+ T lymphocytes infiltration in TS showed better OS in lung cancer patients, whereas high density of FOXP3+ T cells infiltration in TS could be recognized as a negative prognostic factor.
