Abstract
OBJECTIVES: Oropharyngeal squamous cell carcinoma (OPSCC) is divided in two different disease entities depending on HPV involvement. We investigated differences in presenting symptoms and clinical findings in patients with HPV-positive and -negative OPSCC tumors.
METHODS: Altogether 118 consecutive patients diagnosed with primary OPSCC between 2012 and 2014 at the Helsinki University Hospital were included. HPV-status of the tumors was assessed by PCR detection of HPV DNA and immunostaining with p16-INK4a antibody.
RESULTS: Fifty-one (47.7%) of the patients had HPV-positive and 56 (52.3%) HPV-negative tumors. Forty-nine (49/51, 96.1%) of the HPV+ tumors were also p16+ showing high concordance. The most common presenting symptom among HPV+/p16+ patients was a neck mass (53.1%), whereas any sort of pain in the head and neck area was more frequently related to the HPV-/p16- (60.0%) group. HPV+/p16+ tumors had a tendency to locate in the tonsillar complex and more likely had already spread into regional lymph nodes compared with HPV-/p16- tumors. Smoking and alcohol consumption were significantly more common among HPV+/p16+ patients but also rather common among HPV-/p16- patients.
CONCLUSIONS: This analysis of symptoms and signs confirm that OPSCC can be dichotomized in two distinct disease entities as defined by HPV status.
