PRESENCE OF HUMAN PAPILLOMAVIRUS PREDICTS RECURRENCE OF INVERTED PAPILLOMA

Recent evidence suggests that human papillomavirus may play a role in the pathogenesis of inverted papilloma, a benign but locally aggressiv e neoplasm with a high recurrence rate and an association with squamou s cell carcinoma. Histologic features of inverted papilloma have not b een useful in discriminating lesions at high risk for recurrence. We s tudied archival pathology specimens from 32 patients with inverted pap illoma treated at the University of Michigan between 1980 and 1994 wit h polymerase chain reaction techniques and human papillomavirus E6 and L1 consensus primers. Twenty (63%) specimens tested positive for huma n papillomavirus. The clinical status of the remaining 25 patients was reviewed after seven patients with recent diagnosis or who were lost to follow-up were excluded. A significant association was identified b etween the presence of human papillomavirus DNA in inverted papilloma and recurrence after surgical excision. Thirteen of 15 patients whose tumors tested positive for HPV recurred, whereas none of the 10 patien ts whose tumors were human papillomavirus negative recurred (p < 0.000 02). This strongly suggests that the presence of human papillomavirus predicts recurrence of inverted papilloma.
