Brief summary

The purpose of this study is to compare laparoscopic ablation to open ablation of liver malignancies regarding complication rates and ablation response as well as quality of life following the surgery.

Detailed description

Liver malignancies is a major cause of cancer-related mortality and the incidence is increasing. Patients with liver malignancies are often left with limited surgical treatment options due to extensive tumor burden or comorbidities. Ablation is a less invasive treatment for these patients that can be performed percutaneously, by laparoscopy or open surgery. Ablation during open surgery has a high potential of complications. Laparoscopic ablation presumably has a lower complication rate than during open surgery, yet still offers some of the same advantages needed for tumors in locations not favorable for percutaneous ablation. This study aims to compare laparoscopic ablation with ablation during open surgery to investigate a treatment option with a supposed lower complication rate and equally treatment effectiveness after one month.

Interventions

PROCEDURELaparoscopic ablation

Heat-based ablation modality performed by laparoscopy. Centers may use either radiofrequency or microwave ablation. The modality should be the same in both groups.

PROCEDUREOpen ablation

Heat-based ablation modality performed by laparotomy. Centers may use either radiofrequency or microwave ablation. The modality should be the same in both groups.

Design outcomes

Primary

MeasureTime frameDescription
Complications measured by the comprehensive complication index.Complications are registered and clavien-dindo graded 30 days after surgery.Comprehensive Complication Index (CCI) scores compared between open and laparoscopic ablation groups. A higher CCI score represents a larger complication burden.

Secondary

MeasureTime frameDescription
Tumor ablation completeness.30 days after surgery.Presence of tumor remnants in ablation cavity one month after procedure evaluated with contrast enhanced CT.
Quality of Recovery score (QoR)Before surgery and postoperative day 1, 7 and 30.Questionnaires are filled out prior to surgery and after
Quality of Life score (QoL)Before surgery and on postoperative day 30.Questionnaires are filled out prior to surgery and after
Overall survivalUp to 90 days after surgeryOverall and disease-free survival measured as survival status 90 days after surgery.
