Meta-analysis of Prognostic Factors for Overall Survival Among Resected Patients with Spontaneous Ruptured Hepatocellular Carcinoma.

OBJECTIVE

Our meta-analysis was performed to explore the prognostic factors for overall survival among post-hepatectomy patients with spontaneous ruptured hepatocellular carcinoma (SRHCC).

METHODS

PubMed, EMBASE, the Cochrane Library, and Web of Science were all searched up for relevant studies regarding prognostic factors with SRHCC. RevMan5.3 software and Stata 14.0 software were used for statistical analysis.

RESULTS

A total of nineteen studies with 1876 resected SRHCC patients were finally identified. Pooled results indicated that preoperative AFP (high vs low) (P = 0.003), concurrent liver cirrhosis (yes vs no) (P = 0.02), preoperative liver function (child A vs non-child A) (P = 0.0007), tumor size (large vs small) (P < 0.00001), tumor number (solitary vs multiple) (P = 0.002), satellite foci (yes vs no) (P = 0.0006), micro-vascular invasion (yes vs no) (P < 0.00001), type of hepatectomy (major or minor) (P = 0.04), surgical margin (R + vs R -) (P < 0.00001), and type of hepatectomy (emergency hepatectomy vs staged hepatectomy) (P = 0.005) were prognostic factors for overall survival among post-hepatectomy SRHCC patients.

CONCLUSION

Apart from some conventional prognostic factors identified in resected patients with SRHCC, numerous prognostic factors have also been unmasked, which might provide clinical reference to stratify patients with different therapeutic regimes.
