Abstract:
Objective To explore the clinical effects and safety of treatment for colorectal cancer to pulmonary metastases with percutaneous multiple electrodes radiofrequency-2000 (RF-2000) under CT-guided.Methods 26 pulmonary metastatic tumors in 11 cases were treated with RF-2000. The following extents were observed: (1) blood pressure,pulse rate and oxygen saturation during the treatment;(2)the variety of the liver function,the lung function and renal function after treatment;(3) the variety of the volume and low dense shadow of tumors after treatment;(4)the survival rate for 5 years. Results (1) The blood pressure,pulse rate and oxygen saturation were not changed during the treatment;(2) the liver function,the lung function and renal function after treatment were also not changed;(3) the volume of tumors were increased one month after treatment,three months later,23 lesions of 26 tumors were disappeared,2 decreased to more than 80% and 1 to 50%~80% in volume,and the low dense shadow within the tumors appeared as Ⅰtype (less than 50%) in one,Ⅱtype (50%~80%) in 3 and Ⅲ type (more than 80%) in 22;(4)The survival rate for 5 years was 81.82%(9/11). Conclusion The clinical effects and safety of treatment of colorectal cancer to lung metastases with percutaneous radiofrequency-2000 (RF-2000) under CT-guided is excellent.
