    Abstract:
    The incidence of cervical neoplasia in Israeli Jewish women is persistently lower, while that of vulvar carcinoma is comparable to that in other populations. The aim of the present investigation was to assess the prevalence of HPV and of immunohistochemically detected mutant p53 in Israeli Jewish women with cervical and vulvar neoplasia compared with other populations. Tissue sections from formalin-fixed paraffin-embedded blocks of ten patients with CIN III, 29 with invasive squamous cell carcinoma, three with adenocarcinoma and 14 with invasive vulvar carcinoma, were examined for the presence of HPV 16 and HPV 18 DNA by PCR amplification, and for mutant p53 protein by immunohistochemical staining. HPV negative cases were re-examined with a sensitive primer. HPV DNA was detected in eight patients with CIN III and in 23 patients with invasive squamous carcinoma. In the remaining cervical squamous neoplasia tissue analysis with the sensitive primer could not be done. HPV DNA was also detected in two patients with adenocarcinoma and in nine (64.2%) patients with vulvar carcinoma. Positive p53 immunohistochemical staining was found only in one CIN III patient, in six (20.7%) squamous carcinoma and in 11 (78.6%) vulvar carcinoma patients. Of the p53 immunohistochemical staining positive tissues, two with cervical carcinoma and six with vulvar carcinoma were also HPV-positive. The prevalence of HPV and of positive p53 immunohistochemical staining in our series of Israeli Jewish women with cervical and vulvar neoplasia is similar to that in other populations, suggesting that the etiological factors are probably also alike.
