Background:
Hepatic artery chemoembolization (HACE) is a treatment option in the management of metastatic carcinoid. We reviewed our experience to identify potential factors that influence survival.
Methods:
The records of 122 patients with metastatic carcinoid tumor undergoing HACE were reviewed. Log-rank analysis and Cox proportional hazards were applied to identify factors predictive of decreased survival.
Results:
Median follow-up after HACE was 21.5 months. Complications occurred in 23% with periprocedural mortality of 5%. Radiographic tumor regression was seen in 82%, with stabilization of disease in 12%. Median duration of CT response was 19 months. Improvement in symptoms occurred in 92% for median duration of 13 months. HACE resulted in complete normalization of serum pancreastatin in 14%, with greater than 20% reduction in another 66%. Median overall survival was 33.3 months after HACE. Only pancreastatin level > or =5,000 pg/ml was associated with decreased survival by multivariate analysis.
Conclusion:
HACE offers symptom palliation and long-term survival in patients with incurable carcinoid metastases. Although safe, it should be approached cautiously in patients with significant tumor burden as evidenced by pancreastatin levels > or =5,000 pg/ml. We do not recommend whole-liver embolization in these patients but prefer a staged approach to each lobe of the liver.
