Penile HPV-associated lesions are frequently seen in male sexual partners of women with CIN. The natural course and clinical significance of these lesions are unclear. Women with CIN and their male sexual partners were randomized for condom use (condom group n ؍ 68, noncondom group n ؍ 68). Males were screened for the presence of penile lesions, i.e., flat lesions, papular lesions and condylomata acuminata, and of HPV in their penile swabs by PCR testing. Median follow-up time was 13.1 months (range 2.9 -57.4). The outcome of our study was clinical regression of penile lesions defined as disappearance of lesions at penoscopy. Potentially prognostic factors, i.e., HPV status, lesion type and age, were studied as well. Outcomes were assessed in 57 men of the condom group and in 43 men of the noncondom group. Condom use shortened the median time to regression of flat penile lesions (7.4 months condom group vs. 13.9 months noncondom group; HR ؍ 2.1, 95% CI 1.2-3.7). This effect was not found for papular lesions (HR ؍ 0.5, 95% CI 0.1-2.8).
Key words: penile lesion; clinical course; condom use; human papillomavirusInfection with high-risk types of HPV is the main causative agent for cervical cancer and its precursor lesions, i.e., CIN 1-3. 1 The relationship between the natural history of CIN lesions and the presence of HPV has been clarified. 2 However, the number of studies on the clinical behavior of HPV infection in men is limited.Of the male sexual partners of women with cervical lesions, 50 -65% have HPV-associated penile lesions, i.e., flat lesions, papular lesions and condylomata acuminata. [3][4][5] The natural history of these lesions and HPV infection in men are incompletely understood because of the use of either insensitive (in situ hybridization) or unreliable (cytology) techniques for HPV detection in previous studies. [5][6][7] Moreover, penile lesions studied before were often biopsied or treated, resulting in interference with the clinical course.Studying HPV-associated penile lesions is hampered by a clinical pitfall: most of these lesions are flat, cause no clinical symptoms and are difficult to detect by the naked eye unless a careful visual inspection is performed. These lesions are easily detectable using a penoscope and application of acetic acid. Using the latter approach on male sexual partners of women with CIN lesions in a non-STD setting, we observed penile lesions in 68% of cases, with a predominance of flat penile lesions. A smaller number had papular lesions, and only a few had condylomata acuminata. HPV DNA, mainly of high-risk HPV types, was detected by PCR in 59% of penile swabs. 8 Sexual intercourse is the predominant mode of acquiring HPV infection. 9 Previous studies in men have shown that failure to use a condom is associated with HPV infection and that consistent condom use reduces the risk of acquiring genital warts. 10,11 Of interest is the work of Hippelainen et al.,6 who studied the clinical course of HPV infections in men. Most of these men were partners of HPV-inf...
