Future directions of image-guided thermal ablation in colorectal cancer lung oligometastases

Colorectal cancer (CRC) with lung oligometastases, particularly in the presence of extrapulmonary disease, poses considerable therapeutic challenges in clinical practice. We have carefully studied the multicenter study by Hu et al, which evaluated the survival outcomes of patients with metastatic CRC who received image-guided thermal ablation (IGTA). These findings provide valuable clinical evidence supporting IGTA as a feasible, minimally invasive approach and underscore the prognostic significance of metastatic distribution. However, the study by Hu et al has several limitations, including that not all pulmonary lesions were pathologically confirmed, postoperative follow-up mainly relied on dynamic contrast-enhanced computed tomography, no comparative analysis was performed with other local treatments, and the impact of other imaging features on efficacy and prognosis was not evaluated. Future studies should include complete pathological confirmation, integrate functional imaging and radiomics, and use prospective multicenter collaboration to optimize patient selection standards for IGTA treatment, strengthen its clinical evidence base, and ultimately promote individualized decision-making for patients with metastatic CRC.
