Primary prevention of human papillomavirus-dependent neoplasia: No condom, no sex

Abstract

Cervix cancer is one of several neoplastic disorders that arise following transfer of human papillomavirus (HPV) during unprotected sexual intercourse, and like most other sexually transmitted diseases (STDs), is largely preventable by consistent condom use. This primary prevention strategy has received little support, however, when compared with massive secondary prevention initiatives involving cervical screening. The reasons for this anomalous situation are complex, and include: (i) the asymptomatic nature of most primary HPV infections; (ii) widespread ignorance concerning the venereal aetiology of HPV-related cancers; (iii) the common but incorrect belief that condom use does not reduce HPV transmission; (iv) the perceived irrelevance of safe sex campaigns based on reducing transmission of human immunodeficiency virus (HIV) in high-HPV but low-HIV countries such as the Philippines; (v) the promotion of oral contraception by the medical and pharmaceutical sectors as the sexual prophylaxis of choice; and (vi) the assumption that HPV vaccines will solve the problem. Here it is proposed that the high prevalence of non-HIV STDs, including distressing disorders such as genital warts and herpes simplex, can be exploited with greater efficacy as a public health deterrent to unsafe sex and HPV transmission. Targeting a "mutually assured infection" campaign at vulnerable subgroups such as teenagers and oral contraceptive users could help reverse the global expansion of HPV-related cancers. © 2005 Elsevier Ltd.
