Summary: | Aim
Receptor‐binding cancer antigen expressed on SiSo cells (sRCAS1) is responsible for induction of selective immunosuppression. In addition, preclinical studies have shown that sRCAS1 levels may reflect cancer aggressiveness. The main aim of our study was to analyze pre‐ and post‐treatment levels of sRCAS1 in the sera of patients treated for cervical cancer and to evaluate whether the levels change during treatment and their impact on patient prognosis.
Methods
The study included 49 patients suffering from cervical cancer. The early stage cervical cancer patients (14) were treated surgically, while the advanced stage patients (35) underwent radiochemotherapy. Serum sRCAS1 levels were evaluated both before and after intervention with the use of the ELISA method.
Results
We have found that median serum sRCAS1 levels of patients before intervention were not significantly different from the levels assessed after intervention. There were also no differences when pre‐ and post‐treatment levels were compared within the group of early and of advanced stage patients. Serum sRCAS1 levels were not influenced by either the histopathological type of the tumor or the methods of treatment. High post‐intervention sRCAS1 levels indicated shortened OS when compared to low sRCAS1 levels. Neither pre‐intervention sRCAS1 levels nor the alteration in sRCAS1 levels during treatment were associated with patient prognosis. In multivariate analysis, post‐treatment sRCAS1 levels and clinical stage of cervical cancer remained as independent predictors of survival.
Conclusion
High post‐treatment serum sRCAS1 level in cervical cancer patients seems to be a negative prognostic factor for patient overall survival. |
