N2 - Risk factors for vulvar cancer have been evaluated in a case-control study conducted between 1987 and 1990 in northern Italy on 73 women with histologically confirmed invasive vulvar cancer and 572 control subjects in hospital for acute nongynecological, nonneoplastic non-hormone-related conditions. The risk of vulvar cancer was inversely related to education level: with reference to women reporting less than 7 years of schooling, the relative risk estimates were 0.6 and 0.4, respectively, in those reporting 7 to 11 and 12 or more years of schooling (χ1/2 trend = 4.91 P = 0.03). No relationship emerged between number of births and spontaneous or induced abortions. Parous women reporting late first birth tended to be at lower risk (relative risk = 0.5, 95% confidence interval 0.3 to 1.1 for
