A randomized, double-blind, placebo-controlled trial of 5-fluorouracil for the treatment of cervicovaginal human papillomavirus.

OBJECTIVE: To compare intravaginal 5-fluorouracil (5-FU) and placebo for the treatment of cervical and/or vaginal human papillomavirus (HPV).
METHODS: A randomized, placebo-controlled trial was performed. Women with HPV detected visually or by Papanicolaou (Pap) test and confirmed by colposcopic biopsy were randomized to receive either intravaginal 5-FU cream or an intravaginal placebo cream. Women with cervical or vaginal intraepithelial neoplasia were excluded. The primary outcome measure was cytologic regression of HPV as determined by Pap test screening 4 to 6 months after treatment. The secondary outcome was cytologic evidence of disease progression at both the 4-6-month and 12-month follow-up evaluations. Data were analyzed using the Chi square test with significance established at P < 0.05.
RESULTS: A total of forty patients were randomized, and thirty patients had a follow-up Pap test 4 to 6 months after treatment. Of those patients treated with 5-FU, 28% demonstrated regression of HPV on cytologic evaluation, compared with 69% of those treated with placebo (P < 0.05). Twelve-month follow-up cytology was available from 18 of the study participants. There were no significant differences in the frequency of cytologic progression or regression between groups at 12 months.
CONCLUSION: Four to six months post treatment, the use of intravaginal 5-FU for the treatment of cervical or vaginal HPV is associated with a lower rate of regression than the use of placebo.
