In this pilot study, Investigators will assess the feasibility and acceptability of point of care HPV testing in an existing SVA program. There is no control group since neither the efficacy nor effectiveness is to be tested. In the pilot study the screen positive women will be referred to the Tata Memorial Hospital for further diagnostic work-up to restrict the programme logistics. While in the main study, Colposcopy and Cryotherapy will be conducted at the community level. The evaluation framework will be based on a robust D&I model called REAIM.
i.TMH staff will hold health camps to mobilize women to attend. Providers already trained in the TMH outreach program will identify women eligible for screening. After obtaining the consent, the medical social worker will collect baseline data and record the results of the GeneXpert HPV testing on self sample and health care provider collected sample.
ii. Quantitative data: Data will be collected in-person by the Medical Social worker. De-identified data will be uploaded to Own Cloud, a file-sharing program in the University of Arizona, College of Nursing.
ii. Qualitative data: There will be a discussion on cultural appropriateness and possible adjustments to the procedures based on the healthcare providers' experiences with a small subset of the 227 women already screened. Between one to two focus groups will be conducted by the study investigators with assistance from local staff with a subset of women, separately to qualitatively assess acceptability of HPV testing using GeneXpert.
The focus group discussions with women participants will be audio-recorded and transcribed verbatim. The moderator will be guided by a semi-structured set of questions to facilitate discussion, and will specifically probe to elicit distinctive/ unusual behaviors or symptoms related to the program, screening and HPV testing.
In keeping with standards for objective evaluation, Dr. Menon or Kue will conduct a focus group discussion with Medical Social workers at the end of the study period for program evaluation (i.e., acceptability, potential changes in delivery, etc.). Discussions will be recorded by a note-taker, not previously associated with the study.
Given the small numbers, a think-aloud group, in a question and answer format with a note-taker to record the main points will be simply conducted with the providers. Both the facilitator and note-taker will not be among TMH staff as this may introduce bias to the conversation.
iii: Training of TMH staff to use GeneXpert: Personnel from the India office of Cepheid will train providers on how to use GeneXpert using standardized training protocols. The quality of the self- collected sample will be compared to the quality of the provider collected sample (by running two separate GeneXpert tests on each sample) to establish the feasibility of self-sampling.

Cluster of 3000 women
Cluster will be selected from an existing cervical, breast, and oral cancer screening program in Mumbai, India and its surrounding semi-urban and rural areas.
Other: Cluster of 3000 women
An evaluation of the feasibility, reach, adoption and implementation of a cervical cancer screening program where we diagnose HPV using the GeneXpert point of care testing kit prior to VIA and cryotherapy.
- The feasibility of HPV testing as a single visit approach will be summarized using the appropriate descriptive statistics. [ Time Frame: 3 months ]This will be predominantly for counts and percentages for categorical variables (e.g., number of women screened, number of women with incomplete self-collected specimens). In addition to the numbers of participants, the notes from the providers' debriefing regarding culturally appropriateness of HPV testing will be considered.
- Overall agreement between clinician-collected versus self-collected samples will be compared using pairwise t tests [ Time Frame: 3 months ]For all pairwise comparisons, the agreement will be estimated with the kappa statistic and corresponding 95% confidence intervals. McNemar's test shall be used to detect significant differences in the discordant results (p<0.05), indicating systematic differences by assay or sample type in the detection of HPV.
- The focus group data will be analyzed using constant comparative data analysis to identify thematic components and sub-themes. [ Time Frame: 3 months ]The research team will conduct a content analysis taking the following approach set forth by Huberman and Miles.
- The HPV GeneXpert by health care provider and HPV HC2 samples by health care provider will be compared to study the agreement rates. [ Time Frame: 3 months ]For all pairwise comparisons, the agreement will be estimated with the kappa statistic and corresponding 95% confidence intervals. McNemar's test shall be used to detect significant differences in the discordant results (p<0.05), indicating systematic differences by assay or sample type in the detection of HPV.
- Documentation of six different genotypes/ genotype families of HPV from cervical tissue samples, which will inform the development of HPV vaccinations specific to the strains of HPV in India. [ Time Frame: 3 months ]The prevalence and distribution of HPV genotypes in Indian women with cervical cancer and the trends in HPV infections will be summarized using the appropriate descriptive statistics.
- Probe for perceptions about self-collection of vaginal samples to describe acceptability of this process. [ Time Frame: 3 months ]Mainly descriptive statistics in percentage, numbers and description
- Fit a predictive model of HPV infection(s). [ Time Frame: 3 months ]This will be predicted by sexual behavior, sociodemographic and clinical characteristics of the women screened, controlling for the two screening sites. A positive intra-class correlation (ICC) is expected among participants at the same screening site due to commonalities in selection, exposure, mutual interaction, or a combination of those factors. We will fit Linear Mixed Models (LMMs) and Generalized Linear Mixed Models (GLMMs) to account for various levels of correlation among participants (also known as a "mixed-model ANCOVA" (Brown, 2009). We will fit these models using SAS PROC MIXED and GLIMMIX, Version 9.3.
