The planning of the laser liver surgery is followed by an ultrasound examination during which it is possible to establish the relationship of the tumor with other structures in the liver.
A small tumor measuring 3cm requires only two needles, inserted one at a time about 1.5cm apart, larger tumors can be ablated but require more needles. The fiber optics through which the lasers travel are positioned into the tumor, and the lasers are then turned on and monitored in real time by the ultrasound, finally the lasers are removed with the cancer having been ‘melted’ away.
The procedure can be done under a local anesthetic and can be repeated if the cancer returns.
In the United States and Northern Europe metastatic carcinoma is the most common type of liver tumor and often the liver is the only site of residual tumor following resection of the primary lesion.
When it comes to metastatic disease of the liver it is only the complete mechanical ablation of tumor which can lead to curing some patients and for someone who has a small number of tumors - one, two or three hepatic metastases - surgical ablation can cure up to 25% of those patients and, more importantly, prevent up to 90% of 1 year deaths from such cancer.
Systemic conventional chemotherapy usually has limited effectiveness on liver tumors but recently a new technique for tissue ablation has been developed; the process employs radiofrequency energy emitted directly into the tumor
