Resection is surgery, not another form of local ablation
A liver resection removes an anatomical or non-anatomical portion of liver containing the tumor. This is fundamentally different from RFA/MWA, which destroys a target with heat, TACE or SIRT, which treat through the hepatic arterial circulation, and SBRT, which treats from outside the body with focused radiation. The appropriate option depends on whether all clinically relevant disease can be treated while preserving adequate liver function.
The key question is what liver can safely remain
German hepatobiliary centers emphasize individualized planning. Charité notes that major portions of a normal-functioning liver can sometimes be removed because the organ can regenerate, but this must not be generalized to every patient. The safe future liver remnant depends on baseline liver function, cirrhosis or steatosis, prior chemotherapy or radiation, vascular anatomy and the extent of the planned operation.
- Exact tumor diagnosis and pathology
- Number, size and segmental distribution of lesions
- Relationship to portal and hepatic veins and major bile ducts
- Underlying cirrhosis, steatosis or other chronic liver disease
- Current liver-function tests and overall performance status
- Previous chemotherapy, liver surgery, ablation, TACE, SIRT or radiotherapy
- Disease outside the liver and control of the primary cancer
HCC surgery requires special attention to liver reserve
The current EASL HCC framework treats surgery as one part of a multidisciplinary pathway and stresses individualized risk-benefit assessment. HCC frequently develops in chronically diseased or cirrhotic liver, so a technically removable tumor is not automatically safely resectable. Portal hypertension, liver function, tumor stage and transplantation strategy can change the decision.
For liver metastases, the primary cancer matters
Heidelberg and Charité describe liver-metastasis resection as an individual decision based on the underlying cancer, extent of disease and local liver findings. Preoperative systemic therapy can sometimes change resectability. Selected patients may undergo staged operations or combinations of resection with another local treatment when one operation alone is not the best strategy.
Open, laparoscopic and robotic approaches are not interchangeable
Heidelberg publishes both open and laparoscopic liver surgery, while Freiburg describes minimally invasive and robotic techniques within complex visceral surgery. A smaller-incision approach can be valuable in suitable cases, but tumor location, vascular involvement, need for reconstruction, prior operations and extent of resection determine whether minimally invasive surgery is appropriate.
The operation can range from a limited wedge to major hepatectomy
The term hepatectomy covers very different procedures. Some patients need removal of a small peripheral segment, while others require a formal segmentectomy, sectionectomy or removal of a larger liver portion. The operative plan may change after detailed imaging review or intraoperative findings, which is why a generic 'liver surgery' estimate or recovery promise can be misleading.
Major risks include bleeding, bile leak and postoperative liver failure
Liver surgery is major abdominal surgery. Important risks can include bleeding, bile leakage, infection, thrombosis, pulmonary or cardiac complications and insufficient liver function after resection. Individual risk depends on the extent of surgery, liver reserve, comorbidity and whether vascular, biliary or other-organ procedures are required.
Send the full imaging set before travelling
A useful international surgical review should allow the liver team to reconstruct both tumor biology and anatomy.
- Recent contrast-enhanced liver MRI and/or multiphase CT in DICOM format
- Whole-body staging where relevant
- Pathology and molecular reports
- Operative reports from previous abdominal or liver surgery
- Complete systemic-treatment history and response
- Reports of prior ablation, TACE, SIRT or radiotherapy
- Current blood count, liver and kidney function and coagulation results
- A clear question about resectability and alternatives
Recovery planning should include pathology and the next oncology decision
Discharge is not the end of the treatment pathway. Final pathology can change staging, margin assessment and the need for additional systemic treatment or surveillance. International patients should clarify expected inpatient recovery, wound and thrombosis care, when flying is reasonable, who will review final pathology and which team will coordinate follow-up imaging after return home.
