Results
33 patients were HPV-positive and 29 HPV-negative.
Eight patients had no identifiable primary lesion: 5 were HPV+ and 3 HPV- and were excluded from the assessment of the primary lesion.
Nine patients had no lymph node metastases: 4 were HPV+ and 5 were HPV- and were excluded from the morphological evaluation of lymphadenopathy.
Exophytic growth pattern of primary tumour was found in 17/28 (61%) HPV+ OPSCC and in 9/26 (35%) in HPV- OPSCC without statistically correlation,
although it was more frequent in the HPV+ OPSCC (Fig. 9).
The tendency to invade the deep muscular tissues,
both of the masticatory space and the tongue,
was found in 10/28 (36%) HPV+ OPSCC and 17/26 (65%) HPV- OPSCC respectively and was statistically correlated with HPV- OPSCC (Fig. 10).
Regarding the evaluation of the N parameter,
the presence of ENE at CT imaging was found in 7/29 (24%) HPV+ OPSCC and in 2/24 (8%) HPV- OPSCC respectively,
without statistical correlation with HPV status (Fig. 11).
In contrast,
lymph node metastases had the cystic appearance in 14/29 (48%) HPV+ OPSCC and in 5/24 (21%) with high statistical correlation with the presence of HPV (Fig. 12).
