Popis: | Patients with human papillomavirus (HPV) positive tonsillar and base of tongue squamous cell carcinoma (TSCC and BOTSCC, respectively) have a better clinical outcome than those with HPV negative tumours, irrespective of treatment. However, to better individualise treatment, additional biomarkers are needed together with HPV status. In a pilot study, we showed that high numbers of CD8(+) tumour infiltrating lymphocytes (TILs) in HPVDNA+ p16(INK4a+) TSCC indicated a better outcome. Here this study was extended. Totally 203 TSCC and 77 BOTSCC formalin fixed paraffin embedded tumour biopsies, earlier tested for HPV DNA (79% HPVDNA+) and p16(INK4a) from patients treated with curative intention, were analysed for CD8(+) and CD4(+) TILs by immunohistochemistry. Data obtained for 275 patients were correlated to HPVDNA and p16(INK4a) status, overall survival (OS) and disease free survival (DFS). In both HPVDNA+ and HPVDNA+ p16(INK4a+) tumours higher CD8(+) TIL counts correlated to a better 3-year OS (logrank test, both p |
