โœฆ Synopsis

Some studies have shown that human papillomavirus (HPV) infection may play not only an etiologic role in anogenital cancers but also a role in the clinical outcome. The objective of the current study was to determine whether detection of HPV DNA in primary squamous cell carcinomas of the upper aerodigestive tract (UADT) is a prognostic factor in patients with the disease.

METHODS.

The authors analyzed archival specimens of UADT tumors from 101 randomly selected patients with evaluable samples for HPV DNA detection. HPV testing was performed using a general primer-mediated polymerase chain reaction.

RESULTS.

The overall detection rate was 16.8% (17 of 101 specimens). HPV DNA was detected at higher rates in specimens from younger patients and in welldifferentiated tumors. Pharyngeal tumors were more likely to be HPV positive (30.0%) than buccal (10.3%) or laryngeal tumors (15.4%), but the differences were not significant. The detection rate was similar for T1-T2 tumors (17.4%) and T3-T4 tumors (15.6%). However, tumors without lymph node metastasis were more likely to be HPV positive (21.4%) than tumors with lymph node involvement (6.5%).

Kaplan-Meier and Cox regression survival analyses did not show any difference in overall or disease free survival according to HPV detection.

CONCLUSIONS.

Although the HPV DNA detection rate was slightly higher in local than in regionally spread tumors, our results support the hypothesis that it is very unlikely that HPV detection plays any role in the prognoses of patients with UADT squamous cell carcinoma.

## BACKGROUND. Squamous cancers of the upper aerodigestive tract (UADT) are related to the use of tobacco and/or alcohol, and in North America they are more common among the poor. They are usually locoregionally confined at diagnosis, and local treatment with surgery and/or radiation therapy is oft

The role of family history in the multiple occurrence of cancer in the upper aerodigestive tract (UADT) remains unclear. The family histories of close relatives were examined in 167 patients with either hypopharyngeal or cervical esophageal cancer (PhCe cancer) and in 167 control subjects with benig
