Recurrence Mechanisms of Colorectal Adenoma After Resection and a Multi-Omics Research Protocol

We aim to establish a single-cell atlas of primary adenomas, recurrent adenomas, and paired normal mucosa, identify recurrence-associated cell subpopulations and transcriptional pathways, and construct a risk prediction model for recurrence (integrating multi-omics features and clinical variables). Ultimately, we propose a panel of biomarkers that can be used to optimize follow-up strategies and guide potential microbiome-based interventions.

Under the premise of meeting routine clinicopathological requirements, we will collect tissue samples from 30 patients with colorectal adenomas. Each collected adenoma sample will be divided into three equal portions for scRNA-seq, scATAC-seq, and microbiome diversity sequencing, respectively. Two years after sampling, enrolled patients will undergo follow-up colonoscopy. Those in whom adenomas are detected will be classified as the recurrence group, while those without adenomas will be classified as the non-recurrence group. Sequencing data will be jointly analyzed in conjunction with clinical medical records. The tissue specimens obtained will not affect routine diagnosis or treatment outcomes.
