Large HHLA2 expression was detected in 62 instances (81.6%) and low HHLA2 manifestation was presented in 14 instances (18.4%). instances (81.6%) and low HHLA2 manifestation was presented in 14 instances (18.4%). HHLA2 manifestation showed a significant negative correlation with lymph node metastasis (value of less than .05 was considered statistically significant. 3.?Results 3.1. HHLA2 and PD-L1 manifestation in cervical AC HHLA2 protein manifestation was investigated by immunohistochemistry of 76 tumor cells. HHLA2 protein was observed in both membranous and cytoplasmic manifestation in malignancy cell. We assessed the membranous HHLA2 manifestation and HHLA2 staining intensity of malignancy cells was graded as absent, week, intermediate or strong (Fig. ?(Fig.1A,1A, B). The strong and intermediate organizations were combined to 1 1 group that we labelled as high HHLA2 manifestation, and the week and absent organizations were classified low HHLA2 manifestation group. In 97.4% of total tumors, HHLA2 expression was observed. Overall, 81.6% of tumors graded as high expression group and, as low expression group in 18.4% of tumors (Table ?(Table1).1). And PD-L1 manifestation in the tumor cell membrane from 0% to 100% in terms of tumor proportion score was assessed (Fig. ?(Fig.1C,1C, D). PD-L1 manifestation showed in 36 individuals (47.4%) and, 54.9% of patients with high HHLA2 expression were co-expressed PD-L1.

In our study, HHLA2 was indicated in the majority of cervical AC and usually co-expressed with PD-L1. The observed co-expression of HHLA2 and PD-L1 was similar to the pattern reported in osteosarcoma.[17] However, unlike osteosarcoma, HHLA2 and PD-L1 expression in cervical AC is definitely associated with an improved prognosis.[17] Higher HHLA2 expression is associated with delayed malignancy recurrence and PD-L1 expression is associated with long term survival. Moreover, PD-L1 manifestation showed borderline significance as an independent element for prognosis in cervical AC. In humans, HHLA2 manifestation has been investigated in several cancers.[16C20] High.
