Ano-genital neoplasia in renal transplant patients.

Ano-genital neoplasia is about 20 x more common in renal transplant patients than the general population. Neoplasms in the immunosuppressed are more morbid and mortal because: patients are younger; tumors are more undifferentiated; they have more and larger foci; more sites are involved; neoplasms tend to persist, recur and progress; and there are more complications from treatments. Intraepithelial neoplasia engenders some morbidity. Invasion is rarer, but when it occurs, it is always morbid, and all too often mortal. Invasive ano-genital cancer is primarily preventable because the lower genital and anal tracts are accessible to inspection, cytologic screening, endoscopy and biopsy. Prime prevention is avoiding infection with the Human Papilloma Virus (HPV). Next best is detecting HPV/intraepithelial neoplasia early with frequent inspection, cytology and liberal biopsies; and then removing any condylomas or intraepithelial neoplasia that develop.
