Summary

The clinical diagnosis and treatment of small pulmonary nodules (suspected to be lung metastases) in advanced colorectal cancer patients remain controversy. Previous studies have shown that tumor-informed circulating tumor DNA (ctDNA) blood testing can sensitively detect residual cancer. Postoperative ctDNA in colorectal cancer patients is a valuable biomarker to identify minimal residual disease (MRD) after radical resection, which is possibly useful in redefining the risk group of patients and guiding postoperative treatment. This study aimed to explore the clinical value of therapeutic strategies based on tumor-informed ctDNA test in advanved colorectal cancer patients with small pulmonary nodules.

Conditions

  • Advanced Colorectal Cancer
  • Circulating Tumor DNA

Interventions

PROCEDURE

Local treatment

Radical surgical resection, local radiotherapy, radiofrequency ablation (RFA) or interventional therapy (absolute alcohol or cryotherapy). The equipment used for RFA of lung lesions consisted of the radiofrequency generator (CelonLab POWER), cold circulation pump (Celon Aquaflow Ⅲ), radiofrequency needle electrode (Celon proSurge: T20, T30 and T40 is an electrode length of 20, 30 and 40 mm respectively, and maximum output power of 20, 30 and 40 W; Olympus Surgical Technologies Europe, Hamburg, Germany).
