ELISA tests on HNSCC serum samples. Statistical significance was indicated as * for p < 0.05; (A) Serum antibody levels against HPV16 L1 in HNSCC patients. Differential OD between HPV-positive and HPV-negative patients (p < 0.05); (B) HPV16 L1 antibody variation during HPV-positive patient follow-up; (C) HPV16 E7 oncoprotein quantification in serum shows no difference between HPV-positive and HPV-negative patients (p > 0.05); (D) HPV16 E7 oncoprotein variation during HPV-positive patient follow-up.
