Detection of human papillomavirus DNA and p53 gene mutations in human prostate cancer

Prostate. 1996 May;28(5):318-24. doi: 10.1002/(SICI)1097-0045(199605)28:5<318::AID-PROS8>3.0.CO;2-7.


The relationship between integration with human papillomavirus (HPV) and p53 gene mutations in tissues of prostate cancer were examined. Tissue samples analyzed were obtained by total prostatectomy (29 stage B cancer cases) and from autopsy (22 endocrine therapy-resistant metastatic disease cases). HPV DNA was detected in 8 of 51 (16%, 5 in stage B and 3 in autopsy cases) by polymerase chain reaction (PCR) using consensus primers on L1 region. Genotypes of HPV were entirely type 16. Structural abnormalities of p53 gene were detected in 7 of the 22 autopsy cases (32%) by PCR-single-strand conformation polymorphism analysis and direct sequencing. No p53 gene mutation was found in stage B cancer cases. Analysis of mutation spectra revealed clear differences between Japanese and Westerners. There was a significant difference in the mutation frequency between stage B and autopsy cases (p < 0.01, Fisher's exact test). One case showed both integration of HPV and p53 gene mutation in different cancer foci. However, the other cases revealed an inverse correlation between the presence of HPV DNA and p53 gene mutations. These data show that p53 genetic alteration is correlated with the progression of prostate cancer, in contrast to the integration of HPV that may occur in a relatively early stage. In conclusion, this study may indicate that either p53 gene mutation or the presence of HPV's oncogenic protein E6 is involved in the development of prostate cancer.
