Abstract
In this study, we determined the number of peripheral blood circulating tumor cells (CTCs) pre- and post-cryosurgery in patients with colorectal cancer liver metastasis as a reference for understanding the relevance of any changes to the efficacy of cryosurgery. CTC numbers and CTC-related gene expression were measured in the peripheral blood of 55 patients with colorectal liver metastasis at 1 day before and 7 and 30 d after cryoablation using magnetic activated cell sorting (MACS) and fluorescence activated cell sorting (FACS) combined with real-time quantitative PCR (RT-qPCR). The number of CTCs decreased significantly with postoperative time (P < 0.01). Delta cycle threshold values for the CTC-related genes CEA, Ep-CAM, CK18 and CK19 increased significantly after cryoablation. Furthermore, the expression of CEA, Ep-CAM, CK18 and CK19 decreased significantly with time after cryoablation (P < 0.01). RT-qPCR and FACS combined with MACS has significant diagnostic and prognostic value for evaluating the efficacy of cryosurgery in patients with advanced colorectal cancer.

Abstract
Cryoablation and surgery achieve similar removal rates for some colorectal cancer (CRC) liver metastasis removal, and systemic chemotherapy is accepted as the most important approach to improving overall survival (OS) in CRC patients with liver metastases. We aimed to evaluate the potential benefit of cryoablation plus chemotherapy in CRC patients with liver metastases. We retrospectively analyze 63 patients of CRC liver metastasis. There were 32 patients in group A, who have received cryoablation plus chemotherapy, and there were 31 patients in group B, who have received chemotherapy alone. We mainly observe the 2-year survival, the quality of life (QOL), and adverse effects. Patients in group A had a higher 2-year survival rate, better OS, better QOL, and better treatment response than patients in group B. Two-year survival rates were 71.9 and 51.6%,respectively, in group A and group B. The negative conversion rates of carcinoembryonic antigen and carbohydrate antigen 19-9 (CA199) were 57.1 and 61.5%, respectively, in group A, and 22.2 and 30%, respectively, in group B. The tumor shrinkage (a tumor volume reduction of ≥ 30%) rates were 62.5 and 22.6%, respectively, in groups A and B. Performance status remained stable or improved in 16 patients (50%) in group A and eight patients (25.81%) in group B. Cryoablation in combination with chemotherapy may increase the 2-year survival rate and improve QOL in CRC patients with liver metastasis.
