  • 纳入2004-2009年间的5,417,699名接受FIT筛查的台湾受试者,随访至2014年;
  • FIT筛查显著降低了进展期结直肠癌发病率(48.4/10万人 vs. 75.7/10万人,校正后RR=0.66)及结直肠癌死亡率(20.3/10万人 vs. 41.3/10万人,校正后RR=0.60);
  • 相比于近端进展期结直肠癌发病率及近端结直肠癌死亡率(校正后RR分别为0.84及0.72),FIT筛查对降低远端进展期结直肠癌发病率及远端结直肠癌死亡率更为有效(校正后RR分别为0.61及0.56)。

来自Gut上发表的一项前瞻性队列研究结果,对超过500万名接受粪便免疫化学检验(FIT)筛查的台湾受试者进行多年随访后发现,FIT可显著降低34%的进展期结直肠癌发病率及40%的结直肠癌死亡率,对远端结直肠癌的效果尤为明显。

Objective: To measure the effects of faecal immunochemical test (FIT) for colorectal cancer (CRC) screening on overall and site-specific long-term effectiveness of population-based organised service screening.
Design : A prospective cohort study of Taiwanese nationwide biennial FIT screening was performed. A total of 5 417 699 eligible subjects were invited to attend screening from 2004 through 2009 and were followed up until 2014. We estimated the adjusted relative rates (aRRs) on the effectiveness of reducing advanced-stage CRC (stage II+) and CRC death by Bayesian Poisson regression models with the full adjustment for a cascade of self-selection factors (including the screening rate and the colonoscopy rate) and the completeness of colonoscopy together with demographic features.
Results: FIT screening (exposed vs unexposed) reduced the incidence of advanced-stage CRC (48.4 vs 75.7 per 100 000) and mortality (20.3 vs 41.3 per 100 000). Statistically significant reductions of both incidence of advanced-stage CRCs (aRR=0.66, 95% CI 0.63 to 0.70) and deaths from CRC (aRR=0.60, 95% CI 0.57 to 0.64) were noted. FIT screening was more effective in reducing distal advanced-stage CRCs (aRR=0.61, 95% CI 0.58 to 0.64) and CRC mortality (aRR=0.56, 95% CI 0.53 to 0.69) than proximal advanced CRCs (aRR=0.84, 95% CI 0.77 to 0.92) and CRC mortality (aRR=0.72, 95% CI 0.66 to 0.80).
Conclusion: A large-scale population-based biennial FIT screening demonstrates 34% significant reduction of advanced-stage CRCs and 40% reduction of death from CRC with larger long-term effectiveness in the distal colon than the proximal colon. Our findings provide a strong and consistent evidence-based policy for supporting a sustainable population-based FIT organised service screening worldwide. The disparity of site-specific long-term effectiveness also provides an insight into the remedy for lower effectiveness of FIT screening in the proximal colon.
