Surgery is superior to hepatic artery infusion pump insertion as a treatment for metastatic cancer of the liver, according to the report in the Archives of Surgery.
The conclusion comes from a study of the fate of 174 patients treated at the University of Alabama, Birmingham, USA, over a ten-year period.
|Average patient survival (in months) following treatment:|
Surgical resection 70
Artery pump inserted 32
89 patients had operations of which 73 were given surgical treatment for liver metastases.
Of the 73 patients, 52 had lobectomy or wedge resection, 16 had an artery pump inserted and five had cryotherapy.
Patients who had resection lived on average for 70 months compared with a 32 month survival period for those who had pump treatment, the researchers, led by Dr Martin Heslin, reported. Untreated patients lasted on average three months.
The researchers write, "Aggressive surgical management of patients with hepatic colorectal metastases is safe, may prolong overall survival, and therefore should be considered in all patients with metastases confined to the liver."
