Abstract [en]

Objective: To investigate whether the extent of expression of hyaluronan (HA) and epidermal growth factor receptor (EGFR) in squamous cell carcinoma of the mobile tongue can predict the risk of cervical metastasis and survival.

Study design: Retrospective histopathologic study.

Methods: Surgical specimens from 64 patients who had undergone surgery for squamous cell carcinoma of the mobile tongue were assessed using immunohistochemistry to investigate the expression of HA and EGFR in the primary tumours, and the data were then correlated to cervical metastasis and survival.

Results: There was a significant correlation between the intensity of HA staining and patient survival (p .024), and a weak correlation between the staining proportion of EGFR and the risk for regional recurrence (AUC 66).

Conclusions: This study indicates that immunoscoring using HA could be used to provide prognostic tools for tongue cancer, and that it might be of interest to study the prognostic properties of EGFR further concerning the risk for regional recurrence after the primary treatment.

Abstract [en]

Head and neck squamous cell carcinoma is a common form of cancer, and despite improvements in treatment during the last decades, survival rates have not significantly increased. There is therefore a need to better understand how these tumours and the adjacent tissues react to radiotherapy, the most common type of treatment for this group of tumours. In order to improve this understanding, the expression of hyaluronan (HA) and epidermal growth factor receptor (EGFR) and the presence of mast cells were mapped before and after radiotherapy using immunohistochemistry. The results showed HA and EGFR to have similar expression patterns in tumour tissue and histologically normal squamous epithelium prior to radiotherapy. Following radiotherapy, EGFR increased in histologically normal epithelium. An increased number of mast cells were also observed as a result of radiotherapy. No expression of EGFR was observed in the connective tissue either prior to or following radiotherapy.
