Improved selection of patients for hepatic surgery of colorectal liver metastases with 18F-FDG PET: a randomized study
Ruers TJM et al. - In a study to investigate whether the addition of 18F-FDG PET is beneficial and reduces the number of futile laparotomies in pts with colorectal liver metastases, it appears that the number of futile laparotomies was reduced from 45% to 28%; thus, the addition of 18F-FDG PET to the work-up for surgical resection of colorectal liver metastases prevents unnecessary surgery in 1 of 6 pts. Methods- 150 pts with colorectal liver metastases selected for surgical treatment by imaging with CT were randomly assigned to CT only (n=75) or CT plus 18F-FDG PET (n=75).
- Pts were followed up for at least 3 yr.
- Primary outcome measure was futile laparotomy, defined as any laparotomy that did not result in complete tumor treatment, that revealed benign disease, or that did not result in a disease-free survival period longer than 6 mo.
Results- Pt and tumor characteristics were similar for both groups.
- Number of futile laparotomies was 34 (45%) in the control arm without 18F-FDG PET and 21 (28%) in the experimental arm with 18F-FDG PET; the relative risk reduction was 38%.
