[Cost-effectiveness and cost-benefit analysis of upper gastrointestinal cancer screening in Yangzhong City, Jiangsu Province, from 2009 to 2015].

Objective

To evaluate the effectiveness and benefit of the upper gastrointestinal cancer screening in Yangzhong city, Jiangsu province, from 2009 to 2015.

Methods

From 2009 to 2015, 31 natural villages with high-incidence of upper gastrointestinal cancer were selected from Baqiao town, Youfang town and Xinglong sub-district in Yangzhong city. 13 776 residents aged 40 to 69 years old were recruited and screened for upper gastrointestinal cancer by using endoscopic examination and pathological diagnosis. Two economic evaluation methods, cost-effectiveness analysis and cost-benefit analysis, were performed to evaluate the current screening schemes.

Results

The mean age of all respondents were (53.60±8.14) years old and the males accounted for 43.64% (6 012). A total of 502 cases of upper gastrointestinal tract lesions were detected, including 100 cases of cancer (62 cases of esophagus, gastric/cardiac early stage cancer, 38 cases of advanced stage cancer), 38 cases of severe esophageal hyperplasia/carcinoma in situ, and 15 cases of high-grade intraepithelial neoplasia in stomach/cardia, the detection rate was 0.73%, 0.28% and 0.11%, respectively; the early diagnosis rate was 75.16% (115/153). The cost of a precancerous lesion, a case diagnosed at the early stage and a positive case identified through the upper gastrointestinal cancer screening in Yangzhong City was 10 037.17, 30 460.64 and 22 895.25 RMB, respectively. The early detection cost index from 2009 to 2015 was 0.52, 0.56, 0.48, 0.48, 0.21, 0.30, and 0.26, respectively. The effectiveness-cost ratio from 2009 to 2015 was 3.41, 2.77, 2.66, 2.58, 4.99, 3.12, and 3.48, respectively.

Conclusions

The project of early diagnosis and treatment of upper gastrointestinal tract cancer in Yangzhong city has achieved good results and benefits.
