Presence of human papilloma virus in transitional cell carcinoma in Jewish population in Israel.
The possible causal association of human papilloma virus (HPV) with transitional cell carcinoma (TCC) of the urinary bladder in Israeli Jewish patients was assessed. One hundred and ten histopathological TCC sections were examined by peroxidase anti-peroxidase (PAP) method. HPV capsid antigen was demonstrated in 19 out of 110 cases (17.3%). HPV-DNA sequences, determined by in situ DNA-DNA hybridization at high stringency wash were present in 24 cases (21.8%): 16(14.5%) cases proved to be HPV6/11 and 8 (7.3%) were HPV 16/18 positive. Four (3.6%) of the HPV 6/11 positive specimens cross hybridized with HPV 31/33/35 at low stringency conditions. Sixteen samples known to be positive by in situ hybridization were reconfirmed by polymerase chain reaction (PCR). When the PCR was performed on the 43 negative cases, an additional 4(9.3%) HPV positive cases were revealed: two proved to be HPV 6/11 and two HPV 16/18. Comparison of the different methods for HPV detection in 59 TCC histopathological samples, showed good correlation; an overall positivity of 33.9% by PCR, 27.1% by in situ hybridization and 25.4% by PAP was observed. Forty one samples from nontumoral material of the bladder or post mortem specimens served as controls and 4.8% HPV DNA was present in only two cases: one HPV 6/11 and one 16/18. Hence, HPV in TCC of the bladder is detected at a relatively high frequency and might be involved in the pathogenesis of this tumor among Jewish population in Israel.
