New concepts in the therapeutic options of liver metastases from colorectal cancer.

Colorectal cancer is one of the most frequent malignant neoplasms causing approximately 10% of cancer deaths. Up to 30% of patients with primary colorectal cancer have already liver metastatic disease at the time of diagnosis. Untreated patients with liver metastases share a poor prognosis with an average survival of 12 months.

Ultrasound-guided liver biopsy in real life: comparison of same-day prebiopsy versus real-time ultrasound approach.

Background And Aim: Currently, an increasing number of liver biopsies are performed by radiologists under real-time ultrasound control. A routine ultrasound assessment of a puncture site before performing percutaneous biopsy is reported to increase diagnostic yield and decrease complication rates. It is not clear if real-time ultrasound is superior to marking the puncture site before biopsy as regards reducing biopsy size and avoiding fragmentation and complications.
