3502 Background: This current study was an open, prospective and nonrandomized phase II study, which critically evaluated the prognostic parameters for local disease-free survival (DFS) and overall survival (OS) in patients who underwent percutaneous radiofrequency ablation (RFA) for inoperable colorectal pulmonary metastases (CRPM). Methods: The inclusion criteria were patients who had inoperable CRPM, due to number, distribution, poor performance status or patients’ refusal to accept surgery. The exclusion criteria were lesions > 6 per hemithorax; diameter of metastases > 5 cm; bleeding diathesis; and/or significantly compromised lung function. All patients underwent percutaneous RFA with a radiological clear margin of at least 2 cm. The end-points of this study were local DFS and OS, determined from the time of RFA intervention. Ten clinical and six treatment-related prognostic parameters were assessed in univariate and multivariate analyses. All patients were reviewed at one week, one month and every three months thereafter with chest CT. Fifty-five patients entered into the study. The follow-up was complete and the median follow-up was 24 months (6 to 40). Results: The median local DFS was not reached and 2-year local DFS was 57%. Univariate analysis demonstrated that largest size of lung metastasis, location of lung metastases, post-RFA CEA at 1 month and 3 months were significant for local DFS. In multivariate analysis, largest size of lung metastasis of ≤ 3 cm and post-RFA CEA of ≤ 5 ng/ml at 1 month were independently associated with an improved local DFS. The median OS was 33 months (4 to 40), with 1-, 2-, and 3-year survival of 85%, 64% and 46%, respectively. Univariate analysis demonstrated that interval between the diagnoses of colorectal cancer and pulmonary metastasis; largest size of lung metastasis and location of lung metastases were significant for OS. In multivariate analysis, only size of lung metastasis of ≤ 3 cm was independently associated with an improved OS. Conclusions: Percutaneous RFA of inoperable CRPM may have a useful role in patients with a lesion of ≤ 3 cm. No significant financial relationships to disclose.

Objective: To investigate the effectiveness and safety of CT-guided percutaneous radiofrequency ablation for the treatment of secondary hyperparathyroidism (SHPT) in chronic renal failure. Methods: Thirty patients with SHPT in our hospital were selected as the study subjects. Preoperative CT examinations confirmed that there were 1 to 4 hyperplastic parathyroid tissues. Under the guidance of CT, radiofrequency ablation of the hyperplastic parathyroid tissues was performed to detect ablation The levels of PTH, blood Ca, and blood P before and after 10 min, 1 d, 1 week, 1 month, 6 months, and 1 year of ablation were observed to observe the improvement of clinical symptoms and the occurrence of complications. Results: First, the patients' blood PTH levels at 10 min, 1 d, 1 week, 1 month, 6 months, and 1 year after ablation were significantly lower than those before the ablation (P < 0.05); 10 min, 1 d, Blood Ca levels at 1 week, 1 month, 6 months, and 1 year were significantly lower than those before ablation (P < 0.05); 10 min, 1 d, 1 week, 1 month, 6 months, and 1 month after ablation The blood P level in 2015 was significantly lower than that before ablation (P < 0.05). Second, the symptoms of bone pain, itching of the skin, muscle weakness, and anorexia were significantly improved after ablation, and hoarseness occurred in 3 cases. The rate was 10%, all of which remitted spontaneously within 1 week after operation; 2 cases of severe hypocalcemia occurred with a rate of 6.6%. All patients had remission after timely calcium supplementation, and all patients did not relapse. Conclusion: CT-guided percutaneous radiofrequency ablation is a safe and effective method for the treatment of SHPT, which can significantly improve the symptoms of renal bone disease and improve the quality of life.
