简要总结
This study is a prospective, observational and exploratory study to explore the effect of Huaier Granule on the negative conversion rate of patients with increased CEA levels after colorectal cancer surgery.
详细描述
This study is a prospective, single center, observational study, expected to include patients who visited the selected research center from December 2022 to December 2024 and were pathologically diagnosed with stage I-III colorectal cancer and underwent R0 radical resection surgery. During routine clinical follow-up within one year after radical surgery, if serum CEA>5.2ng/ml occurs, patients may choose whether to use Huaier granules to prevent recurrence and metastasis according to their wishes. Patients who agree to use Huaier granules will enter the observation group; Patients who do not agree to use it will enter the control group. After the subjects are enrolled, they will be visited every 1 month ± 7 days in the first year, and every 3 months ± 14 days starting from the second year according to clinical routine diagnosis and treatment, until imaging examination determines disease progression, the end of the study, intolerable toxicity, withdrawal from the study for any reason or death, or the researcher determines no longer benefiting, whichever occurs first.

研究组 & 干预措施
Huaier Granule
Oral administration of Huaier granule, 10g (1 bag) each time, 3 times a day, is recommended for at least 6 months until there is imaging progression of the disease, the end of the study, intolerable toxicity, withdrawal or death from the study for any reason, or the researcher determines that there is no longer benefit, whichever occurs first.
干预措施: Huaier granule (Drug)
结局指标
主要结局
