Evaluation of combined percutaneous radio-frequency ablation and percutaneous ethanol injection after transcatheter arterial chemoembolization for hepatocellular carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the therapeutic effect of combined CT-guided percutaneous radio-frequency ablation (RFA) plus percutaneous ethanol injection (PEI) on nonresectable priminary hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE).</p><p><b>METHODS</b>One hundred fifty patients diagnosed as HCC either by pathology or by AFP combined with typical CT and angiographic image findings were studied, 99 men and 51 women, with an average of 51 years. Each patient had at least 3 lesions, ranging from 3.1 to 7.9 cm in diameter, average 5.0 cm. All patients were randomly divided into group A (control group) and group B (combination group) according to their check-in date (odd or even). In group A, 74 patients were treated with RFA alone two weeks after TACE. In group B, 76 patients were treated with RFA plus PEI two weeks after TACE.</p><p><b>RESULTS</b>The complete necrosis rate was 75.8% in group A and 89.5% in group B (P < 0.05).</p><p><b>CONCLUSION</b>The clinical therapeutic effect of radiofrequency ablation (RFA) combined with percutaneous ethanol injection (PEI) is better than that of RFA alone after TACE in HCC.</p>

Application of~(125)I seed permanent plantation in osseous metastases / 中华放射学杂志

Objective To evaluate the value of ~(125)I permanent plantation in treating osseous metastases.Methods Twenty-two patients with osseous metastases were accepted radioactive seeds ~(125)I permanent plantation.The curative effect was appraised according to the degree of ostalgia relieving and the changing of the radiology imaging in patients.Results Accepted radioactive seeds ~(125)I permanent plantation,relief of pain was obtained and the effective rate is 91%(20/22).However none of the patients showed severe side-effect.Among 32 lesions in 22 cases followed-up by CT in 2 months,4 obtained CR, 18 obtained PR,10 NC and 0 PD.The responsive rate was 68.7%.Conclusion ~(125)I permanent plantation procedure can be a safe and effective method in treating osseous metastases and obtaining good clinical effects with minimal damage and few comnlications.
