研究目的:

主要研究目的 在cT4NxM0/cT1-3N+M0、经根治术治疗且术后腹腔灌洗液CTC和ctDNA均为阳性的胃癌患者中,探索升阶梯HIPEC联合化疗相比标准治疗是否能够降低患者1年内腹膜转移的发生率。 次要研究目的 观察和评价腹腔灌洗液CTC和/或ctDNA状态对cT4NxM0/cT1-3N+M0胃癌腹膜转移的预测作用。 ?比较术前、术后腹腔灌洗液和血液(术后)ctDNA状态/水平对患者1年/2年腹膜转移率,RFS以及OS的预测价值。 探索腹腔灌洗液ctDNA、CTC变化与化疗疗效(ORR、RFS等)之间的相关性(A组:HIPEC+标准治疗(standard of care,SOC)vs SOC)。 探索性研究目的 A组与B组患者在肿瘤病理分期、基本临床资料、胃癌特异性肿瘤标记物之间的差异 基于腹腔灌洗液CTC和ctDNA定义的腹膜转移高危人群的关键基因组特征  

Objectives of Study:

The main study objectives To explore whether ascending-step HIPEC in combination with chemotherapy reduces the incidence of peritoneal metastases within 1 year in patients with cT4NxM0/cT1-3N+M0, gastric cancer treated by radical surgery, and with postoperative peritoneal lavage fluid that is positive for CTC and ctDNA, compared with standard treatment. Secondary study objectives To observe and evaluate the predictive effect of CTC and/or ctDNA status of peritoneal lavage fluid on peritoneal metastasis of cT4NxM0/cT1-3N+M0 gastric cancer. To compare the predictive value of preoperative and postoperative intraperitoneal lavage fluid and blood (postoperative) ctDNA status/levels on patients' 1-year/2-year peritoneal metastasis rate, RFS, and OS. To explore the correlation between changes in ctDNA and CTC in peritoneal lavage fluid and the efficacy of chemotherapy (ORR, RFS, etc.) (Group A: HIPEC + standard of care (SOC) vs SOC). Purpose of exploratory study Differences between patients in group A and group B in terms of tumor pathological stage, basic clinical data, and gastric cancer-specific tumor markers Key genomic characteristics of people at high risk of peritoneal metastases defined based on peritoneal lavage CTC and ctDNA

随机方法(请说明由何人用什么方法产生随机序列):

对于筛选成功且灌洗液CTC和ctDNA检测结果为双阳性的患者,利用信封法进行随机化分组。通过在一个不透光的信封内保存随机分组方案,按入组顺序依次拆开信封,按照信封内的分配方案确定患者的分组情况。

Randomization Procedure (please state who generates the random number sequence and by what method):

Patients who were successfully screened and had double-positive results for CTC and ctDNA in the lavage fluid were randomized into groups using the envelope method.By keeping the randomized grouping scheme in an opaque envelope, the envelopes were opened sequentially in the order of enrollment, and the grouping of patients was determined according to the allocation scheme in the envelope.
