Emerging Therapeutic Approaches to Hepatocellular Carcinoma

Excerpt

Hepatocellular carcinoma (HCC) is one of the most common solid malignancies worldwide, and its incidence is dramatically increasing in the United States. Unlike many other malignancies, treatment of HCC often involves management of two disease processes: liver cancer and cirrhosis. In addition to tumor-specific factors such as tumor size, number, and location, the surgeon also has to consider liver specific factors such as degree of fibrosis/cirrhosis, extent of portal hypertension, and the size of the future liver remnant. As such, therapy for HCC is complex and can involve resection, transplantation, interventional radiology-based liver-directed therapies, and emerging systemic chemotherapeutic and targeted agents. To successfully treat this group of patients, surgical oncologists should be aware of the many and varied approaches to treating patients with HCC. Specifically, surgical oncologists need to know not only how to select patients and perform hepatic resection in appropriate patients with HCC, but also be familiar with the controversy surrounding management of early HCC and identify those factors that may make one therapeutic modality preferable compared with others. In addition, surgical oncologists need to be familiar with the role of intra-arterial regional therapy as “destination” therapy for unresectable HCC, as well as bridge therapy before transplantation/resection. Finally, surgical oncologists need to be aware of the emerging role of systemic chemotherapy for stage IV HCC, as well as its potential future role as adjuvant therapy. In this issue of Annals of Surgical Oncology, a series of review articles have been solicited to provide evidence-based data to equip the practicing surgical oncologist with the knowledge to understand these complex treatment issues.1‐4 …
