The investigation of T-cell receptor subtypes in ovarian cancer: effects on survival and prognostic factors
The aim of this study was to investigate T-cell receptor (TCR) changes in ovarian carcinoma (OC). The study included 24 malignant and 23 benign adnexal masses. DNA was isolated from ovarian samples. Multiplex PCR was used to determine T-cell gene clonality. PCR products were loaded onto polyacrylamide gel electrophoresis and imaged. The relationship between prognostic parameters and T-cell rearrangement was evaluated. In the study group (SG), TCRB-B positivity was higher than control group (CG) and TCRD receptor positivity was higher in CG. In SG, TCRG-B levels were higher in patients with stage I-II tumours compared to stage III. TCRG-B receptor was higher in patients with overall survival of 36 months and above. In our study, subgroups of TCRs were analysed in OC. According to our findings, significant differences in TCRB-B and TCRD subgroups may be applied to immune therapies. Understanding of TCR pathways will provide new treatment approaches in OC.IMPACT STATEMENT
