When heated during a radiofrequency ablation (RFA) procedure to ≥40°C, lyso-thermosensitive liposomal doxorubicin (LTLD) produces high drug concentration in the surrounding margins of the ablation zone. The hypothesis that the RFA + LTLD combination can effectively treat hepatocellular carcinoma (HCC) was investigated in the HEAT study: adding LTLD did not improve the efficacy of normal practice RFA. However, among the 285 patients with a solitary lesion who received at least 45-min RFA dwell time, the hazard ratio for overall survival was 0.63 (95% CI: 0.41-0.96; p = 0.04). The OPTIMA study is currently ongoing to test the hypothesis that adding LTLD to a standardized RFA lasting ≥45 min increases survival compared with standardized RFA alone.
在射频消融(RFA)手术过程中,当加热至≥40°C时,溶热敏感脂质体阿霉素(LTLD)会在消融区周边产生高药物浓度。在HEAT研究中,对RFA + LTLD联合治疗可有效治疗肝细胞癌(HCC)这一假设进行了研究:添加LTLD并未提高常规RFA的疗效。然而,在285例接受至少45分钟RFA驻留时间的单发病变患者中,总生存的风险比为0.63(95%置信区间:0.41 - 0.96;p = 0.04)。OPTIMA研究目前正在进行,以验证与单独的标准化RFA相比,在持续≥45分钟的标准化RFA中添加LTLD是否能提高生存率这一假设。
