Treatment for colorectal cancer with isolated para-aortic lymph node metastasis

Curative Systemic Therapy Sequenced Radical Surgery for Synchronous Isolated Paraaortic Lymph Node Metastasis of Colorectal Cancer

Not applicable Interventional First Affiliated Hospital of Zhejiang University · NCT04774757

This study is testing a new treatment plan that combines medication and surgery for people with colorectal cancer that has spread to nearby lymph nodes to see if it helps them live better and longer.

What this trial studies

This study evaluates the effectiveness and safety of a treatment approach that combines systemic therapy followed by radical surgery for patients with synchronous isolated para-aortic lymph node metastasis of colorectal cancer. Eligible patients will receive up to two lines of systemic therapy, and those who show potential for achieving no evidence of disease will undergo para-aortic lymph node dissection. The study aims to determine if this sequenced treatment can improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with histologically confirmed colorectal cancer and isolated para-aortic lymph node metastasis who can potentially achieve no evidence of disease.

Not a fit: Patients with additional distant metastases or those unable to achieve no evidence of disease will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved survival rates and quality of life for patients with this specific type of colorectal cancer metastasis.

How similar studies have performed: While there is limited data on this specific approach, similar strategies combining systemic therapy with surgical intervention have shown promise in other studies.

2. ECOG PS 0-1
3. Histologically confirmed colorectal carcinoma
4. Synchronous metastatic colorectal cancer with isolated para-aortic lymph node metastases: In the preoperative examination of positron emission tomography CT and abdominopelvic CT, metastasis was noted when the diameter of the PALN was 10 mm or greater and had irregular shape.
