ABSTRACT
The aim of this study was to evaluate the rare postoperative supraclavicular metastasis originating from oral squamous cell carcinoma (OSCC) and to discuss epidermal growth factor receptor (EGFR) as a potential predictive marker. Tumour specimens of OSCC patients divided into three groups were included supraclavicular metastasis (n = 8), conventional cervical metastasis (n = 28), no metastasis (n = 48). Basic information and EGFR expression were compared among these groups and the data were analysed to identify potentially related risk factors for supraclavicular metastasis. In the supraclavicular metastasis group (n = 8), all primary tumours were T1-T2 and located in the tongue and buccal region; five of eight cases were pathologically N0. The median interval from the primary tumour resection to the development of supraclavicular metastases was 21.5 months. All related deaths (5/8) occurred within 2 years. In the supraclavicular metastasis group, EGFR expression was highest in the supraclavicular metastases, followed by cervical lymph nodes, and was lowest in the primary tumours (P = 0.39). In contrast, in the conventional metastasis group and the N0 group, EGFR expression was higher in the primary tumours than in the lymph nodes (P < 0.01). Supraclavicular metastasis of OSCC is infrequent and associated with a poor prognosis. EGFR might predict the occurrence of supraclavicular metastasis.
