研究目的:

本研究的目的是, 采用目标试验模拟框架, 比较高风险腺瘤 (除结直肠癌外)患者高质量结肠镜完全切除腺瘤后的两种随访策略, 术后 3 年进行一次结肠镜监测(低频监测)与术后 3 年内进行多次结肠镜监测(高频监测),随访期间累积进展期肿瘤 (Advanced Neoplasia,AN) (进展期肿瘤包含结直肠癌)发现率的差异。本研究假设,低频监测策略在随访期间累积进展期肿瘤发现率上不劣于(数值不低于)3 年内多次监测策略。特别说明,本研究在使用高风险腺瘤一词时,不包含结直肠癌;使用进展期肿瘤一词时,包含结直肠癌。  

Objectives of Study:

The objective of this study is to use a target trial simulation framework to compare two follow-up strategies for patients with high-risk adenomas (excluding colorectal cancer) following high-quality complete endoscopic resection of the adenoma: colonoscopic surveillance once every 3 years postoperatively (low-frequency surveillance) versus multiple colonoscopic examinations within 3 years postoperatively (high-frequency surveillance), with regard to differences in the cumulative detection rate of advanced neoplasia (AN) (which includes colorectal cancer). This study hypothesizes that the low-frequency monitoring strategy is non-inferior (i.e., the rate is not lower) to the multiple-monitoring strategy within 3 years in terms of the cumulative detection rate of advanced neoplasia during the follow-up period. It should be noted that in this study, the term “high-risk adenoma” does not include colorectal cancer, whereas the term “advanced neoplasia” does include colorectal cancer.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄大于等于 50 岁且小于等于 75 岁;
2.首次结肠镜检查前从未行结肠镜检查、未接受过结肠镜息肉切除术;
3.首次结肠镜检查肠道准备充分, 进镜到达盲肠,退镜时间大于 6 分钟,术者满意。(符合上述条件的结肠镜检查定义为高质量结肠镜检查。这一定义较USMSFT 定义更有可操作性。);
4.首次结肠镜检查发现高风险腺瘤,并在内镜下完全切除。(高风险腺瘤定义为: 3~10 个非进展期腺瘤,或至少 1 个进展期腺瘤。 本研究对高风险腺瘤的定义稍不同于 USMSTF:不含结直肠癌,不含发现 11 个或以上腺瘤的情况。

Inclusion criteria

1. 50 years of age or older and 75 years of age or younger; 2. Never had a colonoscopy or undergone colonoscopic polypectomy prior to the first colonoscopy; 3. For a first-time colonoscopy, bowel preparation is adequate; the scope reaches the cecum; the withdrawal time exceeds 6 minutes; and the operator is satisfied. (A colonoscopy meeting the above criteria is defined as a high-quality colonoscopy. This definition is more practical than the USMSFT definition.); 4. A high-risk adenoma was identified during the initial colonoscopy and completely resected endoscopically. (High-risk adenoma is defined as: 3 to 10 non-advanced adenomas, or at least 1 advanced adenoma. The definition of high-risk adenoma used in this study differs slightly from that of the USMSTF: it excludes colorectal cancer and cases in which 11 or more adenomas were found.)

排除标准:

1.家族性腺瘤性息肉病病史。
2.Lynch 综合征病史。
3.炎症性肠病病史。
4.结直肠癌病史。
5.结直肠手术史。
6.首次结肠镜检查的息肉病理不明确,无法判断是否高风险腺瘤。
7.首次结肠镜检查发现腺瘤数量大于 10 个(不含 10 个)。

Exclusion criteria:

1.History of familial adenomatous polyposis.
2.Medical history of Lynch syndrome.
3.History of inflammatory bowel disease.
4.History of colorectal cancer.
5.History of colorectal surgery.
6.The pathology of the polyps found during the first colonoscopy was inconclusive, making it impossible to determine whether they were high-risk adenomas.
7.More than 10 adenomas (excluding 10) were detected during the initial colonoscopy.

Measure method:

If one or more of the following conditions are met, the patient is deemed to have an advanced neoplasia (AN) detected during this colonoscopy: 1. The adenoma is ≥10 mm in size. The endoscopist’s direct observation and documentation during the procedure shall serve as the basis for this determination.2. The adenoma exhibits villous structures on histopathological examination. Based on the hospital’s standard pathological testing procedures, specific histological types—such as villousstructures (i
