The aim of this study is to reveal the certain human papillomavirus (HPV) genotype distribution between cervical cancer and esophageal cancer in the both high-incidence geographic regions. For this study, we collected and detected the infection of HPV in 120 paraffin-embedded esophageal tissues and 152 paraffin-embedded cervical tissues, respectively. The esophageal tissues include 40 normal epithelium (ENOR), 26 dysplasia (DYS), and 54 invasive squamous cell carcinoma (ESCC). The cervical tissues consisted of 40 normal epithelium (CNOR), 53 intraepithelial neoplasia (CIN), and 59 invasive squamous cell carcinoma (CSCC). Both esophageal and cervical tissues collected in this study came from the same area, in which both the ESCC and CSCC were in high incidence, Xinjiang province, China. HPV GenoArray test kits were served to analyze the HPV infection. The result shows that among the 59 CSCC tissues, the total infection rate of HPV was 98.3% (58/59). The positive rate of HPV-16 i nfection was 63.8% (37/58). It indicated that HPV-16 is the most common infection among all of the high-risk HPV. The multiple infection rate was 19.0% (11/58). Among the 54 ESCC, a total of 7 genotypes were detected. The total infection rate of HPV was 61.1% (33/54). The positive rate of HPV-16 infection was 63.6% (21/33). The multiple infection rate was 6.1% (2/33). Our result shows that high-risk-type HPV-16 was associated with both cervical cancer and esophageal cancer, which play a role in the high-incidence area in Xinjiang. We hope that our results could point out the direction for the treatment strategy of HPV-associated cancer, cervical cancer, and esophageal cancer and for the application of HPV vaccines in the future.
