2. BENIGN LIVER MASS
Hepatic Adenoma
Focal Nodular Hyperplasia
Liver Hemangioma
Liver Cysts
◦ Simple cyst
◦ Cystadenoma
MALIGNANT LIVER MASS
Hepatocellular carcinoma (95% in Liver Cirrhosis)
Intrahepatic Cholangiocarcinoma
Metastatic cancer to the liver
◦ Colon and rectal cancer
◦ Neuroendocrine cancer (NET)
◦ Soft tissue sarcoma
◦ Breast cancer
◦ Ovarian/Prostate cancers
◦ Others
3. Liver Mass
Most without symptoms upon presentation
Incidental findings on abdominal CT scan or MRI
Symptoms :
◦ Right upper quadrant fullness/discomfort/pain
◦ Elevated liver enzymes
◦ Jaundice
4. Diagnostic Work-Up
Liver enzymes (ALT, AST, Tbili, Alkaline phosphatase)
Triple tumor markers (AFP, CA 19-9, CEA)
Triphasic Liver CT scan (arterial, portal, washout phase)
Liver MRI (lesions <2cm)
Liver mass seen on Ultrasonography needs a Triphasic Liver CT scan
5. Available Treatment Modalities
Liver Resection (Robotic, Laparoscopic, Open, Hybrid technique)
Radiofrequency Ablation (Laparoscopic, Percutaneous, Open for lesions
< 3.5 cm diameter)
Regional Liver Therapy
◦ Transarterial Chemoembolization
◦ Transarterial Radioembolization
◦ Hepatic Artery Infusion Pump / Isolated Hepatic Perfusion Therapy
Focused External Beam Radiation
Liver Transplantation (shortage of donor, limited eligibility criterias, lifelong immunosuppression post
transplantation)
6. Hepatic Adenoma
Young female in reproductive age
Estrogen dependent (Oral contraception/Injection
most common)
Malignant degeneration and risk of
rupture/bleeding as size increases
Liver resection indicated for size > 4-5cm
9. Liver Cyst
Benign
Right upper quadrant discomfort from capsular
stretch
Can be very large >10cm in size / > 1 gallon of
fluid
Frequently multiple in both hemilivers
Robotic or Laparoscopic cyst wall resection /
fenestration
10. Hepatocellular Carcinoma
95% occur in background liver cirrhosis
In the US : Alcohol, Hepatitis C
Typical appearance on CT scan
Liver resection / Radiofrequency Ablation /
Liver Transplantation depending on stage
11. Intrahepatic Cholangiocarcinoma
Malignancy of intrahepatic bile duct
Normal background liver
Tend to spread to portal lymphnodes
Response to standard chemotherapy only 40%
Liver resection with negative margin --> only
potentially curative treatment
12. Metastatic Cancer to the Liver
Most common origin is colon and rectal cancer (60%)
Most are found incidentally during CT scan A/P
Most centers gives neoadjuvant 2-3 months followed
by surgery
No limit on number of lesions resected
Liver resection ± Radiofrequency ablation
13. Evolution of Liver Surgery
Traditional Liver Surgery Minimally Invasive Robotic/Laparoscopic Liver
Surgery
14. Minimally Invasive Robotic/Laparoscopic Liver Surgery
1. Less postoperative pain
2. Less blood loss
3. Shorter hospital stay
4. Lower perioperative complications & improved recovery
5. Lower wound-related complications (Infection and hernia)
6. Similar oncologic outcomes
7. Better cosmesis
