Current management of hepatic tumors

Area of Science:

• Hepatology
• Surgical Oncology
• Medical Imaging

Background:

• Hepatic tumors are diagnosable with imaging, but precise localization is limited by inability to visualize the interlobar fissure noninvasively.
• Exploratory laparotomy followed by resection is the preferred treatment for resectable hepatic tumors in suitable patients.
• Percutaneous biopsy is generally discouraged unless laparotomy is not planned.

Purpose of the Study:

• To discuss the therapeutic strategies and outcomes for benign and malignant liver neoplasms.
• To highlight the advancements in surgical techniques for liver tumor resection.
• To evaluate the efficacy of various chemotherapeutic approaches for unresectable liver cancer.

Main Methods:

• Review of current diagnostic modalities including isotope scans, arteriogram, and ultrasonic imaging.
• Discussion of surgical approaches, emphasizing resection as the primary curative therapy.
• Analysis of systemic and intra-arterial chemotherapy, and hepatic dearterialization for unresectable disease.

Main Results:

• Resection is the mainstay for potentially curative treatment of hepatic malignant tumors.
• Surgical mortality rates have decreased due to improved understanding of hepatic anatomy and surgical innovations.
• Chemotherapeutic strategies (systemic, intra-arterial, dearterialization) show modest value with low response rates and rare long-term tumor control for unresectable liver cancer.

Conclusions:

• Surgical resection, when feasible, offers the best prospect for cure in patients with hepatic tumors.
• While chemotherapy provides limited benefit for unresectable liver cancer, ongoing research explores combination therapies.
• Continued advancements in surgical techniques are crucial for improving outcomes in liver tumor management.
