Summary

Comparative evaluation of efficacy and safety of high-resolution anoscopy (HRA)-guided topical treatment (trichloroacetic acid, TCA) vs. surgical treatment (electrocautery, ECA) in HIV-positive patients for human papillomavirus (HPV)- induced AIN, an anal cancer precursor. The primary hypothesis is that cost-saving and simple TCA treatment is non-inferior to the current best option therapy with ECA. TCA treatment would also be possible in the normal setting of a doctor´s office without extensive specialization and without complex technical equipment.

Conditions

  • Anal Intraepithelial Neoplasia (AIN) in HIV-infected Patients

Interventions

OTHER

Topical 85% trichloroacetic acid (TCA)

In the experimental intervention arm, all visible lesions are treated with 85% TCA by dipping the wooden stick end of a cotton swab into a cup containing TCA. The stick end is saturated with TCA and is inserted through the anoscope and directed to the lesion under HRA guidance. TCA is applied to the lesion repeatedly until the lesion changes to a dense white colour. Each TCA application session is followed by another appointment four weeks later, where the clinician re-evaluates the lesions of the patient and determines whether a next TCA application is necessary up to a maximum of four times

PROCEDURE

Surgical electrocautery (ECA)

In the control arm, HRA-guided ECA, is performed every 4 weeks up to a maximum of four times. All visible lesions are ablated at every visit. Bleeding from small vessels can be stopped by ECA. Patients undergo local anaesthesia if necessary
