title: Possible prognostic significance of human papillomavirus type in cervical cancer.
abstract: While several different human papillomaviruses (HPV) have been associated with cancer of the cervix, it is yet to be determined if specific HPV types have clinical or prognostic significance. To address this question, 30 cases of invasive carcinoma (squamous carcinoma, adenosquamous carcinoma, and adenocarcinoma) with HPV DNA sequences detectable in the tissue were analyzed. HPV type was determined by Southern blot DNA hybridization. Clinical information was obtained by chart review, and all biopsy and surgical specimens were reviewed microscopically without knowledge of HPV type. HPV 16 was detected in 14 cases, HPV 18 in 6, and HPV 31 in 2. In eight samples there were distinctly different, but as yet uncharacterized, HPV DNAs. Of the factors evaluated, tumor grade was found to have a statistically significant relationship to HPV type. Eighty-three percent of HPV 18-associated tumors were grade 3 tumors (5 of 6) as compared to only 7% of HPV 16-associated tumors (1 of 14) (P = 0.002). Age at diagnosis and nodal status in relation to HPV type exhibited a trend but were not statistically significant. The mean age of the HPV 18 group was 37 years, compared to 49 years for the HPV 16 group. Similarly, among Stage IB cancers, nodal involvement was associated with 60% of HPV 18 cases (3 of 5) as compared with 36% of HPV 16 cases (4 of 11). These observations suggest that HPV 18 may be associated with a more aggressive form of cervical cancer than other HPV types.
