Abstract

Oral squamous cell carcinoma (OSCC) are frequently infiltrated by tumour infiltrating lymphocytes (TILs) which may demonstrate specific anti-tumour cytotoxicity. We have used a panel of family-specific primers in reverse-transcriptase (RT)-polymerase chain reactions (PCR) to determine the TCR Vβ repertoire of TILs in the primary and metastatic tumours in patients with OSCC. We observed a diverse and heterogeneous usage of the TCR Vβ genes by TILs in the primary tumours, a scenario not unlike normal oral mucosal lymphocytes. In one patient with a longstanding history of OSCC, the repertoire was restricted. Restricted TCR Vβ gene usage also occurred in TILs of metastatic tumours. Within individual patients, discrepancies of TCR Vβ gene usage were also observed between TILs in the primary OSCC and those in metastatic lymph nodes. Work is ongoing to determine the clonality and functional significance of these TILs.
