This project aims to improve screen and treat programmes for cervical cancers by discovering the best method of treatment. The specific aims are
- To develop, test and produce 20 novel lightweight hand-held cordless, portable battery driven and rechargeable Thermal Coagulators (Liger Medical, Utah).
- To evaluate the success / failure rate of Thermal Coagulation in a randomised controlled trial comparing thermal coagulation to the existing current standard cryocautery and to Large Loop Excision of the Transformation Zone (LLETZ aka LEEP) as part of a screen and treat programme in Zambia.
- To evaluate the user satisfaction scores of the Liger Thermal Coagulator cryocautery as part of a screen and treat programme in Zambia.
- To determine the rate of over treatment of VIA positive women as revealed by histopathological examination of the randomly assigned excised treatment cases.
- To determine the value of Z scan to predict normality and abnormality in VIA positive women randomly assigned to excisional therapy
In collaboration with a medical devices company in Utah, the engineering performance of the Liger Thermal Coagulator has been developed and tested in vitro and in vivo. 200+ Liger units have been produced and a randomised controlled trial of the device has been undertaken, compared to cryocautery and LLETZ using efficacy and user friendliness as endpoints. The inclusion of a study arm of excisional therapy allows to quantify the rate of overtreatment in VIA programmes and using the Z scan may allow for a non invasive method of accurately predicting normality and abnormality in VIA positive women.

Experimental: Thermocoagulation (device)
VIA Positive women will be treated by the new device for thermocoagulation
Procedure: Thermocoagulation (device)
Thermocoagulation uses heat injury to destroy the abnormal dysplastic cells of the cervix
Active Comparator: Cryotherapy (device)
VIA positive women will be treated by cryotherapy
Procedure: Cryotherapy (device)
Cryotherapy uses cold injury to destroy the abnormal dysplastic cells of the cervix
Active Comparator: LEEP (device)
VIA Positive women not suitable for thermo-coagulation or cryotherapy will be treated by LEEP
Procedure: LEEP (device)
The abnormal area of the cervix is excised with a thin metallic loop driven by electrosurgical unit
- Difference in proportions with no lesions at 12 months follow-up between the thermocoagulation and cryotherapy arms among VIA positive women treated at baseline [ Time Frame: 12 months ]The VIA positive women will be followed up after 12 months to see if the lesions have disappeared. HPV test will be used as the test of cure
- Over-treatment defined as the number of VIA positive women found with no CIN lesions in the post-operative LEEP specimens [ Time Frame: 12 months ]The LEEP specimens will be subjected to histopathology to check for presence of cervical intraepithelial neoplasias
