抜粋

Human papillomavirus (HPV) infection is known to be an independent etiologic factor for oral squamous cell carcinoma (OSCC). Especially, HPV-16 is associated with a significant risk of developing OSCC. The most important prognostic factor in OSCC is local lymph node metastasis (LNM); therefore, knowledge of LNM status is crucial for selecting proper treatment plans. However, it is not clarify relationship between HPV-16 infection and LNM in OSCC. The purpose of this study was to determine the role of HPV-16 infection in LNM in OSCC. We analyzed 130 cases of OSCC (100 cases of OSCC without LNM; 30 cases of OSCC with LNM). HPV-16 infection was detected by PCR, immunohistochemical examination and in situ hybridization. HPV-16 positivity rates among primary tumor (PT) specimens without LNM were 43.0 % (43/100), and HPV-16 positivity rates among PT specimens with LNM were 26.7 % (8/30). In addition, HPV-16 positivity rates in both PT and LNM specimens in 30 OSCC patients with LNM were 10 % (3/30). OSCC with HPV-16 DNA detected by PCR showed positive staining on immunohistochemical examination and in situ hybridization. The HPV-16 infection rate in OSCC with LNM was significantly lower than that for OSCC without LNM. In the case of OSCC with LNM, HPV-16 infection rates for both in PT and LNM were low. This suggests that HPV-16 positive cases had a significantly lower risk of LNM when compared with patients having HPV-16 negative OSCC. The results of the present study suggest that HPV status in OSCC is able to act as a marker for risk of LNM.
