Tumor-infiltrating lymphocytes predict survival outcomes in patients with cervical cancer treated with concurrent chemoradiotherapy
To (i) identify correlations between selected immunogenic factors and clinicopathological characteristics, (ii) determine whether intratumoral abundance of various specific tumor-infiltrating lymphocytes (TILs) is a prognostic indicator in women with Stage II and III cervical cancer who undergo treatment with cisplatin-based concurrent chemoradiotherapy (CCRT), and (iii) investigate subtypes of FOXP3 In this retrospective study, intratumoral lesions in colposcopic biopsies from 55 women with advanced cervical cancer who subsequently underwent CCRT at our institution were subjected to automatic immunological staining using the following six mouse monoclonal antibodies: anti-CD3, anti-CD4, anti-CD8, anti-CD20, anti-CD206, and anti-FOXP3. Associations between the findings on automatic scoring of the number of each type of TIL in each specimen and various clinicopathological characteristics were analyzed, as were associations between the abundance of various specific types of TIL and survival. Subtypes of FOXP3 Infiltration with CD8 The abundance of various specific intratumoral TILs may be prognostic indicators in patients with advanced cervical cancer undergoing CCRT.
