The Effect of Neoadjuvant Chemotherapy on Lymph Node Metastasis of FIGO Stage IB1-IIB Cervical Cancer: A Systematic Review and Meta-Analysis

Abstract Background: Tumor microenvironment (TME) plays a particularly important role in the progression, invasion and metastasis of cervical carcinoma (CC). Tumor-associated macrophages (TAMs) are significant components of cervical cancer microenvironment. However, the result of studies on the correlation between TAMs and progression in CC is still controversial. This research is aimed at investigating the relationship between TAMs and progression in CC.Method: A total of 100 patients with CC were included in this study. The correlation between TAMs and clinicopathologic features was studied. Also, a systematic literature search was conducted from legitimate electronic databases. This is the first meta-analysis to specifically evaluate the role of different types of TAMs in TME of cervical cancer.Results: In the meta-analysis, high stromal CD68+ TAMs density was relevant to lymph node metastasis (WMD = 11.89, 95% CI 5.30 to 18.47). At the same time, CD163+ M2 TAM density was associated with lymph node metastasis (OR = 2.42, 95% CI 1.09 to 5.37; WMD = 39.37, 95% CI 28.25 to 50.49) and International Federation of Obstetrics and Gynecology (FIGO) stage (WMD = -33.60, 95% CI -45.04 to -22.16). This was confirmed in 100 experimental studies of CC. It supported a critical role of TAMs as a prospective predictor for cervical cancer.Conclusion: Taken together, CD68+ TAM and CD163+ M2 TAM infiltration in cervical cancer was association with tumor progression. And CD163+ M2 TAM infiltration was associated with more advanced FIGO stage and lymph node metastasis in CC.

Tumor microenvironment (TME) plays a particularly important role in the progression, invasion and metastasis of cervical carcinoma (CC). Tumor-associated macrophages (TAMs) are significant components of the tumor microenvironment in CC. However, the results of studies on the correlation between TAMs and progression in CC are still controversial. This research aimed to investigate the relationship between TAMs infiltration and progression in CC. A total of 100 patients with CC were included in the study. The correlation between TAMs and clinicopathologic features was studied. Besides, a systematic literature search was conducted from legitimate electronic databases to specifically evaluate the role of TAMs in TME of cervical carcinoma. In the meta-analysis, high stromal CD68+ TAMs density was relevant to lymph node metastasis (WMD = 11.89, 95% CI 5.30 to 18.47). At the same time, CD163+ M2 TAM density was associated with lymph node metastasis (OR = 2.42, 95% CI 1.09 to 5.37; WMD = 39.37, 95% CI 28.25 to 50.49) and FIGO stage (WMD = -33.60, 95% CI -45.04 to -22.16). This was further confirmed in the experimental study of 100 tissues of cervical cancer. It supported a critical role of TAMs as a prospective predictor of cervical cancer. In conclusion, CD68+ TAM and CD163+ M2 TAM infiltration in CC were associated with tumor progression. And CD163+ M2 TAM infiltration was associated with more advanced FIGO stage and lymph node metastasis in CC.
