Early ?-fetoprotein response predicts survival in patients with advanced hepatocellular carcinoma treated with sorafenib.


ABSTRACT:

Background

It is not clear whether tumor marker responses can predict survival during sorafenib treatment in hepatocellular carcinoma (HCC). We investigated whether the ?-fetoprotein (AFP) response is associated with survival in patients with advanced HCC treated with sorafenib.

Methods

We retrospectively reviewed the records of 126 patients with advanced HCC treated with sorafenib between 2007 and 2012. An AFP response was defined as >20% decrease from baseline. At 6-8 weeks after commencing sorafenib, AFP and radiological responses were assessed by modified Response Evaluation Criteria in Solid Tumors.

Results

The median overall survival (OS) and progression-free survival (PFS) were 6.2 and 3.5 months, respectively. Of the study population, a partial response (PR) was identified in 5 patients (4.0%), stable disease (SD) in 65 patients (51.6%), and progressive disease (PD) in 57 patients (44.4%), respectively. AFP non-response was an independent prognostic factor for poor OS (median 10.9 months for AFP response vs 5.2 months for AFP non-response), together with Child-Pugh B, tumor diameter ?10 cm, and portal vein invasion (all P<0.05), and PFS (median 5.3 months for AFP response vs 2.9 months for AFP non-response), together with tumor diameter ?10 cm and portal vein invasion (all P<0.05). SD or PR was more frequently found in AFP responders than in non-responders (72.1% vs 47.0%, respectively; P=0.007). In a sub-group with SD, OS (median 12.7 vs 5.8 months, respectively) and PFS (median 9.1 vs 3.7 months, respectively) were significantly longer in AFP responders than in non-responders (all P<0.05).

Conclusion

Early AFP response may be useful for predicting survival in patients with advanced HCC treated with sorafenib.
