Primary Hepatic Carcinoid Tumours: Clinical Features with an Emphasis on Carcinoid Syndrome and Recurrence

Abstract

This study sought to determine the clinical profiles and optimal management of primary hepatic carcinoid tumours. The clinical features of nine Chinese patients and 64 patients reported in the English-language literature were characterized. Recurrence rate and survival analysis were performed with the Kaplan-Meier method. The impact of surgical resection and post-operative recurrence on survival was determined by means of the log-rank test. Carcinoid syndrome complicated 10 cases (14%). Sixty-two patients (85%) underwent surgical resection. Actuarial 5- and 10-year survival rates for resected patients were 80% and 75%, respectively. Twelve patients experienced recurrences: the recurrence rate at 5 years post-operatively was 26%. All patients with resectable recurrent disease achieved good long-term survival and no significant relationship was found between recurrence and survival. Owing to the high incidence of recurrence, long-term follow-up is necessary and it is recommended that recurrent cases should be managed with judicious surgical resection.
