Although there have been recent advances in surgery,
radiotherapy, and
chemotherapy, the survival of patient with
glioma remains poor. Increased expression of
polymeric immunoglobulin receptor (pIgR) in
tumor tissue has been detected in various
cancer forms. However, the clinical relevance of pIgR in
glioma remains unclear. The aim of this study was to assess the prognostic value of pIgR in patients with
glioma after surgical resection. pIgR expression was evaluated by immunohistochemistry in
paraffin-embedded
glioma tissues from 146 patients. The relation between pIgR expression and clinicopathologic factors and long-term prognosis in these 146 patients was retrospectively examined. The prognostic significance of negative or positive pIgR exspression in
glioma was assessed using Kaplan-Meier survival analysis and log-rank tests. Positive expression of pIgR was statistically significantly associated with poor prognosis of patients with
glioma. Our results indicated that pIgR could be a novel predictor for poor prognosis of patients with
glioma after surgical resection.
