OBJECTIVE: To explore the appropriate strategies which are suitable for the areas with diverse health and economic resource settings in China by estimating the life outcomes and cost-effectiveness of several cervical cancer screening strategies. METHODS: Markov model was used to calculate the long-term effectiveness, utility, benefit and cost among screened and unscreened cohorts in rural and urban areas, and then analyses of cost-effectiveness, cost-utility and cost-benefit were performed. The assessed screening strategies were acetic acid of visual inspection combined with Lugol's iodine staining (VIA/VILI), conventional Pap smear and simple HPV DNA testing (careHPV) in rural areas, and conventional Pap smear, simple HPV DNA testing (careHPV), HPV DNA testing (HC2) and liquid-based cytology (LBC) alone or combined with HPV DNA testing (LBC+HC2) in urban areas. We estimated the life outcomes and cost-effectiveness of the above screening strategies at one-year, 3-year and 5-year intervals. RESULTS: All of the screening strategies were effective to decrease cervical cancer mortality and to increase life years, with a trend of shorter screening interval having better effectiveness. However, no matter in urban or rural areas, compared with careHPV testing at 5-year interval, the costs of other screening strategies were 1.28 - 13.86 folds, 1.31 - 14.14 folds, and 1.27 - 12.80 folds higher to avoid one death, to save a year of life, and a QALY, and the benefit per cost of other screening strategies was 9.9%-90.2%. CONCLUSIONS: careHPV testing at 5-year interval has the best cost-effectiveness performance and the highest benefit-cost ratio with the moderate life outcomes. It is the optimal cervical cancer screening strategy to be generalized in our country. careHPV testing at 3 years interval can be considered in more developed areas to achieve better effectiveness.
