[Radiofrequency ablation (RFA) in colorectal cancer with hepatic metastases].
We considered the appropriateness of RFA, which was performed in three cases of colorectal cancer with hepatic metastases accompanied by liver cirrhosis. Case 1 involved a patient with sigmoid colon cancer ss, n1 (+) with severe hepatic dysfunction and synchronous hepatic metastases (S5, S6, S8) in which RFA was performed. After 1 year and 6 months, recurrence (S3, S4) was detected in the residual liver, and the patient is currently undergoing the IFL (CPT-11/5-FU/Leucovorin) treatment. In case 2, following a partial hepatic resection, RFA was performed for cecal cancer ss, n2(+) with synchronous hepatic metastases (S5, S6, S8). After 11 months, recurrence (S5, S6, S7) occurred in residual liver and again RFA was performed following a partial hepatic resection. Lung metastases have occurred and currently IFL (CPT-11/5-FU/Leucovorin) and WHF treatments are underway. In case 3, 4 years and 8 months after cancer of the descending colon ss, n1 (+), RFA was performed on asynchronous hepatic metastases (S5, S7, S8). The patient died of peritonitis carcinomatosa one year after RFA. In all three cases, metastases were identified by dynamic CT as low density masses with no blood flow. Necrosis in all three metastases and local control had been achieved. There were no severe complications. Under the current conditions, local coagulation methods including RFA are appropriate in those cases in which resection are not possible such as multiple metastases with severe hepatic dysfunction, etc.
