Issues: HIV+ women are at increased risk for invasive cervical cancer (ICC). Visual inspection with acetic acid (VIA) is an inexpensive technique demonstrated as safe, feasible and acceptable; has sensitivity comparable to cytology; and was associated with a 24% decrease in ICC in a large Indian study of the general population. It also allows immediate treatment with cryotherapy in a single-visit approach. Limited data exists on performance of VIA/Cryotherapy in the setting of HIV infection.
Description: From January to December 2009, Jhpiego implemented VIA/Cryotherapy programs at 7 sites in Guyana (2 HIV sites, 5 sites serving the general population). HIV status was by self-report. Data was collected regarding VIA findings, treatment, and need for referral due to large lesion/suspicion of ICC. A chi-square test was used to compare findings among HIV+ women vs. HIV-/unknown.
Lessons Learned: January - December 2009, 5000 screened women
[Findings: VIA/Cryotherapy among 5000 women]
|All Project Sites||Number of new VIA screenings conducted||Number (%) of new clients with a VIA positive result (n=5000)||Number (%) of eligible* new VIA+ clients receiving immediate cryotherapy
(n=5000)||Number (%) of referrals for large lesions** (n=5000)|
|HIV positive||401||86 (21%)||39 (71%)||31 (36%)|
|HIV negative/status unknown||4599||815 (18%)||577 (84%)||127 (16%)|
|Total||5000||901 (18%)||616 (83%)||158 (18%)|
| || || ||*Not all women who are VIA positive are eligible for cryotherapy||** Large lesions include those that occupy more than 75% of the cervix.|
Conclusions: HIV+ women required referral for large lesions more frequently than HIV negative/unknown women (36% versus 16%, p< 0.001). This has significant program implications, including increased need for referral and/or incorporation of excisional treatment for HIV+ women - requiring additional training and resources.
Most women, regardless of HIV status, received cryotherapy during the same visit. This supports the feasibility of single-visit screening and treatment, thus reducing loss-to-follow up.
No significant association existed between HIV status and VIA positive rates. This may be because of incorrect distribution by HIV status, since this was self-reported, or that these HIV positive women have varying degrees of immune suppression and, thus, risk of dysplasia.
