Methods and materials
This study was approved by the institutional review board.
Between November 2011 – November 2017,
pathologically confirmed RCCs were reviewed retrospectively.
We treated T1 stage RCC patients using LPN until January,
2015.
After that,T1 stage RCC was treated with fusion-imaging guided RFA.
Twenty cases were included in RFA group and twenty four cases were included in LPN group.
To evaluate its technical insufficiency,
we defined primary technical success as the percentage of patients who underwent complete response (CR) of tumor in CT within 48 hours after treatment.
And technical effectiveness was defined as the percentage of patients who underwent CR on the CT taken one month after treatment.
Through the primary technical success,
technical effectiveness,
hospital day,
creatinine value,
estimated glomerular filtration rate (eGRF),
hemoglobin,
complication and disease-free survival rate,
we compared outcome of the RFA and LPN.
All results were analyzed by independent t-test through MedCalc software.
