Fast-track pathways for diagnosing colorectal cancer (CRC) have been implemented in several European countries. In Sweden, a substantial number of CRC are diagnosed via the Swedish Standardized Course of Care for colorectal cancer (SCC-CRC). We evaluated the SCC-CRC in terms of CRC yield, and predictive values and odds ratios (OR) for the entry criteria.
We retrospectively analyzed all 2539 patients referred for SCC-CRC colonoscopy between September 2016 and December 2020. Entry criteria and colonoscopy outcomes were analyzed.
CRC yield was 16.4%. Highest positive predictive values (PPVs) were seen for abnormal radiology (PPV 30.5%, OR 4.7 (95% CI 3.4-6.4) < 0.001), abnormal rectal examination (PPV 28%, OR 3.6 (95% CI 2.7-4.8) < 0.001), and anemia (PPV 24.8%, OR 2.2 (95% CI 1.5-3.1) < 0.001). Some entry criteria showed no significant risk increase, i.e., visible blood in stool/rectal bleeding, change in bowel habits, and the combination of changed bowel habits plus anemia. A positive fecal immunochemical test (FIT), although not part of the SCC-CRC, showed the highest OR: 9.9 (95% CI 4.5-21.7) < 0.001) and PPV of 18.8%.
CRC yield from the SCC-CRC is slightly higher compared to other European fast tracks. A number of entry criteria showed no benefit towards assessing CRC risk. FIT testing should be included in CRC fast tracks to increase diagnostic efficacy.
多个欧洲国家已实施了结直肠癌(CRC)的快速诊断途径。在瑞典,相当数量的CRC是通过瑞典结直肠癌标准化护理流程(SCC-CRC)诊断出来的。我们从CRC检出率、入选标准的预测值和比值比(OR)方面对SCC-CRC进行了评估。
我们回顾性分析了2016年9月至2020年12月期间因SCC-CRC结肠镜检查而转诊的所有2539例患者。分析了入选标准和结肠镜检查结果。
CRC检出率为16.4%。放射学异常的阳性预测值(PPV)最高(PPV为30.5%,OR为4.7(95%CI 3.4 - 6.4)<0.001),直肠指检异常(PPV为28%,OR为3.6(95%CI 2.7 - 4.8)<0.001),以及贫血(PPV为24.8%,OR为2.2(95%CI 1.5 - 3.1)<0.001)。一些入选标准未显示出显著的风险增加,即粪便中可见血液/直肠出血、排便习惯改变以及排便习惯改变加贫血的组合。粪便免疫化学试验(FIT)呈阳性,尽管它不是SCC-CRC的一部分,但其OR最高:9.9(95%CI 4.5 - 21.7)<0.001),PPV为18.8%。
与其他欧洲快速诊断途径相比,SCC-CRC的CRC检出率略高。一些入选标准对评估CRC风险并无益处。CRC快速诊断途径应纳入FIT检测以提高诊断效率。
