Preoperative Predictors Including the Role of Inflammatory Indices in Predicting Early Recurrence After Re-resection for Recurrent Hepatocellular Carcinoma.

BACKGROUND

Repeat liver resection (RLR) for recurrent HCC (rHCC) is a widely accepted treatment modality. However, early recurrence rate is high, frequently resulting in futile resection. We performed this study to evaluate preoperative factors, including the value of inflammatory indices, in predicting early (<1 year) recurrence in patients who underwent RLR for rHCC. This may help clinicians better select patients for RLR, while excluding cases in which RLR for rHCC would likely be futile.

METHODS

This is a retrospective study of 80 patients where 90 operative cases of RLR and 84 cases of early recurrence (<1 year) post-RLR were evaluated. Preoperative predictors of early recurrence and overall survival (OS) were assessed.

RESULTS

There were 31 (34.4%) early recurrences with a 5-year OS of 38.9%. Elevated platelet-to-lymphocyte ratio (PLR) >103.6 was a significant independent preoperative predictor of both early recurrence, relative risk (RR) 4.284 (P = 0.001) and OS, RR 2.139 (P = 0.027), while alphafetoprotein (AFP) ≥ 200 was a significant independent preoperative predictor of early recurrence only, RR 11.655 (P = 0.030). Patients were followed-up at a median of 14.3 months with 54.8% developing intrahepatic recurrences and 19.4% developing extrahepatic recurrences.

CONCLUSION

Both, elevated PLR and AFP ≥ 200 were independent predictors of early (<1 year) recurrence after RLR for rHCC, while only an elevated PLR was an independent preoperative prognosticators of overall survival. Indication for RLR should be carefully discussed in patients with relapsed HCC with an elevated PLR, due to the potential of early recurrence and poor overall survival.
