Core Tip

Core Tip: It remains controversial whether patients who have reached no evidence disease after resection of pulmonary metastasis of colorectal cancer (CRC) can benefit from adjuvant chemotherapy (ACT). We aimed to evaluate the efficacy of ACT in patients after resection of pulmonary metastasis resection from CRC. Due to the lack of randomized prospective trials and high level evidence, our study may support valuable data support for individual participant data meta-analysis and help further research on this type of disease.
