Abstract
Background and Study Aims

In this study we assessed rates and determinants of survival in people with untreated chronic HCV infection and hepatocellular carcinoma (HCC) in an Egyptian liver clinic setting.

Patients and Methods

This is a prospective cohort study of patients diagnosed with HCV-related HCC and undergoing HCC management at a national liver centre in Egypt in 2013–2014 and with a follow-up through 2016.

Results

A total of 345 patients diagnosed with HCV-related liver cirrhosis complicated by HCC were included. Median age at diagnosis was 57 years (IQR = 52, 62), the majority were male (78%) and Child-Turcotte-Pugh (CTP) class A (64%). At diagnosis Barcelona Clinic Liver Cancer staging (BCLC) was 0 (8%), A (48%), B (20%), C (17%), and D (7%). Most common HCC management modalities were transarterial chemoembolization (TACE) (42%), and radiofrequency ablation (RFA) (21%). Median survival following HCC was 22.8 months. Factors associated with poorer survival in adjusted analyses were INR (HR = 1.81, p = 0.01), alpha-foeto protein (AFP) ≥200 (HR = 1.41, p = 0.02), higher CTP score (HR = 2.48, p < 0.01), and advanced BCLC stage (HR = 1.85, p < 0.01). One year survival in patients with CTP A, B, and C was 85%, 71% and 32%, respectively. One year survival following RFA, TACE, combination RFA/TACE, and sorafenib was 93%, 79%, 80% and 60%, respectively.

Conclusion

Survival following HCV-HCC in Egyptian patients undergoing HCC management in a specialised clinic setting is poor, although similar to high income country settings. CTP score is a key determinant of survival, even following adjustment for BCLC stage and HCC management.
