Purpose: To study the association between pretreatment serum hepatitis B viral (HBV) DNA copy numbers and clinical outcome of non-small cell lung cancer (NSCLC) patients with chronic HBV infection.
Patients and methods: We retrospectively evaluated the medical records of NSCLC HBV (+) patients between January 2008 and December 2010. The HBV DNA copy numbers and other prognostic factors including albumin (ALB), C-reactive protein (CRP), platelet, neutrophil–lymphocyte ratio (NLR), platelet–lymphocyte ratio (PLR), and Glasgow Prognostic Score (GPS) were obtained before any antitumor treatment. Kaplan–Meier curves and the log-rank test were used to calculate prognostic significance. A multivariable Cox proportional hazard regression was modeled to analyze the independent prognostic factors for NSCLC HBV (+) patients. All independent prognostic factors in the Cox multivariable analysis were used to build a nomogram. The predictive accuracy of HBV DNA, TNM stage and nomogram was evaluated with the concordance index (C-index) and time-dependent receiver operating characteristics (ROC) curves, and simultaneously compared with traditional TNM staging system respectively.
Results: A total of 188 patients were recruited in this study; the median age was 56 years, and the median overall survival (OS) was 34 months. Cox multivariate analysis results showed independent factors for OS including TNM stage (P=0.028), treatment (P=0.002), HBV DNA (P<0.001), and GPS (P=0.026). The nomogram model for survival was built based on four prognostic factors. The C-index for HBV DNA was 0.67, 0.69 for TNM stage, and 0.76 for the nomogram model. There was no statistical difference between HBV DNA and TNM stage (P=0.48). However, the C-index values of nomogram model were statistically higher both than HBV DNA (0.76 vs 0.67, P<0.001), and TNM stage (0.76 vs 0.69, P<0.001).
Conclusion: Pretreatment serum HBV DNA copy numbers can act as a prognostic marker of survival for NSCLC patients with chronic HBV infection.
