    Abstract:
    AIM: To preliminarily evaluate the effect of microwave ablation (MWA) alone on platelet (PLT) and coagulation function in patients with BCLC-A hepatocellular carcinoma (B-A-HCC) using a retrospective method. MATERIALS AND METHODS: A total of 36 patients with 48 B-A-HCCs were radically treated with MWA alone under the guidance of ultrasound between April and October 2018. PLT coagulation indexes were measured before and after MWA at 1 day, 3 days, 1 week, and 2 weeks, and blood samples (after morning fasting) were collected from cubital veins. Coagulation indexes included prothrombin time (PT), prothrombin activity (PTA), thrombin time (TT), Activated Partial Thromboplastin Time (APTT), international standardized ratio (INR), plasma fibrinogen (FIB), plasma antithrombin III (AT-III), and D dimer (DD). Overall survival (OS), recurrence-free survival (RFS), local tumor progression (LTP), and adverse reactions were also recorded. RESULTS: All patients were radically treated with MWA alone. The median size of the lesion was 2.6 (1.5-7.0) cm3. On the first day after MWA, the level of PLT decreased significantly compared with the values before MWA and gradually returned to preoperative levels one week after MWA. One day after MWA, the levels of PT, INR, and AT-III increased markedly and the level of PTA decreased significantly, all of them gradually returned to baseline after 3 days to a week of time. 1, 3, and 7 days after MWA, the levels of FIB, and DD increased significantly, and the level of TT decreased significantly; all of them gradually returned to baseline at 2 weeks. At 6 months posttreatment, the OS and RFS rates were 100% and 91.7%, the LTP rates was 5.6%, no significant adverse reactions. CONCLUSION: PLT and coagulation indexes were abnormal in patients with B-A-HCC who were radically treated with MWA alone after treatment; without specific treatment, they all gradually returned to baseline within a week or two.
