Background:
The impact of single round screening by visual inspection with acetic acid (VIA), cytology, or human papilloma virus (HPV) testing on cervical cancer incidence and mortality is investigated in a cluster randomised controlled trial in India.
Women aged 30-59 years in 52 clusters of 497 villages in Osmanabad District, India, were randomised to a single round of screening by trained midwives with either VIA (N=34,149), cytology (N=32,136), HPV testing (N=34,515) or to a control group (N=30,378).
All laboratory tests were done locally. Test-positive women had further investigations (colposcopy/biopsy) and treatment in the base hospital (NDMCH).
Data on participation, test positivity, cervical intraepithelial neoplasia (CIN) detection and treatment rates were analysed. We report the preliminary findings after the screening phase (February 2000 to November 2003).


Objectives:
  • To evaluate the reduction in cervical incidence and mortality associated with single round of screening with VIA, cytology or HPV testing, as compared to a control group with no screening
  • To evaluate the cost-effectiveness (CE) of the above three approaches
To evaluate:
  • The determinants of participation for screening/diagnosis/treatment Safety and effectiveness of cryotherapy by nurses
  • Safety and effectiveness of LEEP by mid-level clinicians
  • Over-treatment associated with treatment decisions based on colposcopy

Conclusions:
  • Over 75% of women complied with invitation to screening
  • Over 80% of screen-positive women investigated and treated
  • VIA has a higher test positivity rate (14%) than cytology (7%) and HPV testing (10%)
  • VIA detected significantly higher CIN 1 as compared with cytology and HPV testing (p<0,001)
  • VIA detected significantly lower CIN 2-3 than for cytology (p=0,005); cytology and HPV testing have similar detection rates
  • VIA is a useful alternative, but requires careful monitoring and quality assurance
  • HPV testing is not associated with improved detection of CIN 2-3 lesions compared to cytology, despite high investments
  • With minimal investments in training and quality assurance, good quality cytology can be achieved
  • The ultimate effectiveness of the 3 approaches will become clear with follow-up for cancer incidence and mortality
