Abstract:

Objective: To investigate the role of glycolipid transfer protein (GLTP) in neoadjuvant chemotherapy combined with immunotherapy followed by radiotherapy for locally advanced cervical cancer and its prognostic value. Methods: mRNA and clinical data of 306 cervical cancer patients from The Cancer Genome Atlas (TCGA) and 300 patients from the GSE44001 dataset were screened and downloaded. Weighted gene co-expression network analysis (WGCNA) was used to identify prognosis- and immune-related modules in cervical cancer patients, and the target gene GLTP was selected. Batch effect correction was performed to adjust for batch differences in gene expression data of locally advanced cervical cancer from TCGA and GSE44001, followed by dataset integration. The expression of GLTP mRNA in cervical cancer tissues versus normal tissues was analyzed using TNMplot and GEPIA websites. 41 patients with locally advanced cervical cancer [FIGO stage (2018 edition) ⅠB3-ⅣA] diagnosed and treated at The First Affiliated Hospital of Hebei North University from January 2021 to January 2022 were enrolled to analyze the relationship between GLTP expression and clinicopathological characteristics, as well as prognostic factors. The IOBR software package (MCP-counter method) was employed to analyze the association of GLTP with immune cells and immune checkpoint-related molecules. Results: GLTP was identified as both an immune-related module gene and a prognosis-related gene in cervical cancer from the TCGA database through WGCNA. Analysis via TNMplot and GEPIA showed that GLTP mRNA expression was significantly higher in cervical cancer tissues than that in normal tissues (all P<0.05). Immunohistochemical staining revealed a higher positive-expression rate of GLTP in cervical cancer tissues compared with normal tissues (68.29% vs. 43.90%, P=0.026). Significant differences in PD-L1 expression and objective response were observed between GLTP-positive and GLTP-negative patients (all P<0.05). Multivariate COX regression analysis indicated that patients with an effective objective response (HR=6.096, 95%CI: 2.242-16.573, P<0.001) and positive expression of GLTP (HR=9.115, 95%CI: 3.006-27.639, P<0.001) had a higher cancer-specific survival (CSS) rate after treatment. The overall CSS rate was better in GLTP-positive patients than in GLTP-negative patients (Log-rank P<0.001). Receiver operator characteristic curve analysis showed that GLTP had a certain predictive value for cervical cancer prognosis (the area under the curve is 0.742). Using a cut-off value of 6.67, 266 patients were divided into high- and low-GLTP-expression groups. Spearman correlation analysis revealed a negative correlation between GLTP expression and immune score (r=-0.19, P<0.001). The high-GLTP-expression group exhibited lower numbers of T cells, CD4+T cells, cytotoxic T lymphocytes, natural killer cells, as well as lower expression of immune checkpoint related molecules TIGIT, CD160, LAG3, CD200R1, CD276, CTLA4, CD27, CD40LG, CD244, CD200, CD48 and ICOS, compared with the low-GLTP-expression group (all P<0.05). Conversely, expression of TNFRSF25 and TNFRSF9 were higher in the high-GLTP-expression group (all P<0.05). Conclusions: GLTP is highly expressed in cervical cancer tissues and influences the prognosis of patients receiving neoadjuvant chemotherapy combined with immunotherapy followed by radiotherapy, suggesting its potential as a predictive biomarker for immunotherapy efficacy.
