| 1 | Chemotherapy plus percutaneous radiofrequency ablation in patients with inoperable colorectal liver metastases显示文摘AIM:To access the efficacy of chemotherapy plus radiofrequency ablation(RFA)as one line of treatment in inoperable colorectal liver metastases.METHODS:Eligible patients were included in three PhaseⅡstudies.In the first study percutaneous RFA was used first followed by 6 cycles of 5-fluorouracil,leucovorin and irinotecan combination(FOLFIRI)(adjunctive chemotherapy trial).In the other two,chemotherapy(FOLFIRI or 5-fluorouracil,leucovorin and oxaliplatin combination)up to 12 cycles was used first with percutaneous RFA offered to responding patients (primary chemotherapy trials).RESULTS:Thirteen patients were included in the adjunctive chemotherapy trial and 17 in the other two.At inclusion they had 1-4 liver metastases(up to 6.5 cm in size).Two patients died during chemotherapy.All patients in the adjunctive chemotherapy trial and 44%in the primary chemotherapy studies had their metastases ablated.Median PFS and overall survival in the adjunctive study were 13 and 24 mo respectively while in the primary chemotherapy studies they were 10 and 21 mo respectively.Eighty one percent of the patients had tumour relapse in at least one previously ablated lesion.CONCLUSION:Chemotherapy plus RFA in patients with low volume inoperable colorectal liver metastases seems safe and relatively effective.The high local recurrence rate is of concern. | Joseph Sgouros James Cast Krishna K Garadi Maria Belechri David J Breen John RT Monson Anthony Maraveyas | 2011 | World Journal of Gastrointestinal Oncology2011，3，4： | 4 |
