Background
Nutritional status assessment is essential in cancer patients because a poor nutritional status has been associated with poor outcomes; however, the impact of rapid turnover proteins (RTPs), such as prealbumin, transferrin, and retinol-binding protein, on the outcomes of hepatocellular carcinoma (HCC) has not been well-investigated. We therefore examined the prognostic significance of RTPs in patients with HCC after curative resection.
Methods
This study included 150 patients who underwent elective hepatic resection for HCC between January 2011 and December 2018. The prealbumin, transferrin, and retinol-binding protein levels were classified into two groups (high vs. low); the RTP score (0–3) was calculated as the sum of each RTP measurement (high = 0; low = 1). We retrospectively investigated the relationship between the RTP score and disease-free and overall survival.
Results
Multivariate analysis showed that a high RTP score (P = 0.022), presence of sarcopenia (P = 0.001), and stage III or higher (P = 0.005) were independent predictors of disease-free survival, while a high RTP score (P < 0.001), presence of sarcopenia (P = 0.017), and stage III or higher (P = 0.012) were independent predictors of overall survival. In patients with high RTP scores, positive hepatitis B and C viral infection, high indocyanine green (ICG) at 15 min (ICGR15), Child–Pugh grade B, poorly differentiated carcinoma, and postoperative ascites were more common than in patients with low RTP scores.
Conclusion
The preoperative RTP score may be a prognostic factor in patients with hepatocellular carcinoma after hepatic resection, suggesting an important role of RTP in the assessment of nutritional status in cancer patients.
