ClinConnect Summary

The goal of this clinical trial is to compare in newly diagnosed patients with resectable rectal cancer with lateral lymph node metastasis. The main questions it aims to answer are:

* Evaluate the effectiveness and safety of Forfoxiri combined with lateral lymph node dissection, and optimize the treatment plan for rectal cancer patients with resectable lateral lymph node metastasis.
* Using multiple omics techniques to identify and confirm specific molecular markers for chemotherapy response, lateral lymph node metastasis, and distant metastasis in rectal cancer, in order to achieve the go...

• • Subjects voluntarily join the study and sign the informed consent.
• Exclusion Criteria:
• • A history of malignancy at other sites, excluding curable non-melanic skin cancer and carcinoma in situ of the cervix;
• • Unable to complete MRI;
• • Preoperative examination indicated the need for combined organ resection;
• • Allergic to 5-Fu and platinum drugs; Inability to swallow oral medications;
• • The patient is under thrombolytic or anticoagulant therapy, has bleeding diathesis or coagulation dysfunction, or has occurred in the past year Aneurysm, stroke, transient ischemic attack, arteriovenous malformation;
