Recurrent cervical intraepithelial neoplasia in human immunodeficiency virus-seropositive women.

OBJECTIVE

To determine the effect of human immunodeficiency virus (HIV) infection on the rate of recurrence of cervical intraepithelial neoplasia (CIN) after standard ablative therapy, and to correlate the degree of immunosuppression with treatment results.

METHODS

The clinical courses of 44 HIV-positive women with CIN were compared with those of 125 HIV-negative women. Patients were treated with cryotherapy, laser therapy, or cone biopsy per standard indications and were followed with cytology at regular intervals, with a range of follow-up of 3-43 months.

RESULTS

Seventeen of 44 HIV-positive women (39%) developed biopsy-proven recurrent CIN, compared to 11 of 125 HIV-negative women (9%) (P < .01). The distributions of CIN severity, lesion size, and modality of treatment were similar in the two groups. In HIV-negative patients, recurrent CIN was associated with increasing grade, but in HIV-positive patients, recurrence was related to increasing immunosuppression. The mean CD4 count in HIV-positive patients with recurrence was 239/mm3, compared to 367/mm3 in HIV-positive patients who remained free of CIN. Only 18% of HIV-positive patients with CD4 counts over 500/mm3 had recurrence, compared to 45% of those with CD4 counts under 500. There was a trend toward poorer treatment results with the use of cryotherapy in HIV-positive patients. All recurrences occurred in patients whose mode of acquisition of HIV was heterosexual transmission.

CONCLUSION

Recurrence rates of CIN after standard treatment in HIV-positive women are high, and recurrence is related to immune status in this high-risk group. Therapeutic strategies that address these treatment failures should be developed for HIV-seropositive women.
