AIM To observe the effect of targeted therapy with 64-slice spiral computed tomography(CT) combined with cryoablation for liver cancer.METHODS A total of 124 patients(142 tumors) were enrolled into this study. According to the use of dual-slice spiral CT or 64-slice spiral CT as a guide technology, patients were divided into two groups: dual-slice group(n = 56, 65 tumors) and 64-slice group(n = 8, 77 tumors). All patients were accepted and received targetedtherapy by an argon-helium superconducting surgery system. The guided scan times of the two groups was recorded and compared. In the two groups, the lesion ice coverage in diameter of ≥ 3 cm and < 3 cm were recorded, and freezing effective rate was compared. Hepatic perfusion values [hepatic artery perfusion(HAp), portal vein perfusion(p Vp), and the hepatic arterial perfusion index(HAp I)] of tumor tissues, adjacent tissues and normal liver tissues at preoperative and postoperative four weeks in the two groups were compared. Local tumor changes were recorded and efficiency was compared at four weeks post-operation. Adverse events were recorded and compared between the two groups, including fever, pain, frostbite, nausea, vomiting, pleural effusion and abdominal bleeding.RESULTS Guided scan times in the dual-slice group was longer than that in the 64-slice group(t = 11.445, p = 0.000). The freezing effective rate for tumors < 3 cm in diameter in the dual-slice group(81.58%) was lower than that in the 64-slice group(92.86%)(χ2 = 5.707, p = 0.017). The HAp and HAp I of tumor tissues were lower at four weeks post-treatment than at pretreatment in both groups(all p < 0.05), and those in the 64-slice group were lower than that in the dualslice group(all p < 0.05). HAp and p Vp were lower and HAp I was higher in tumor adjacent tissues at post-treatment than at pre-treatment(all p < 0.05). Furthermore, the treatment effect and therapeutic efficacy in the dual-slice group were lower than the 64-slice group at four weeks post-treatment(all p < 0.05). Moreover, pleural effusion and intraperitoneal hemorrhage occurred in patients in the dual-slice group, while no complications occurred in the 64-slice group(all p < 0.05). CONCLUSION64-slice spiral CT applied with cryoablation in targeted therapy for liver cancer can achieve a safe and effective freezing treatment, so it is worth being used.
