Abstract Background This study aimed to evaluate the prognostic value of maximal standard uptake values (SUVmax) of 18F-fluoro-2-deoxy-D-glucose positron emission tomography (PET) comparing with Epstein-Barr virus (EBV) DNA levels in de novo metastatic nasopharyngeal carcinoma (NPC) patients. Methods From December 2006 to December 2016, 253 de novo metastatic NPC patients assessed by PET/ computed tomography were involved in current study. SUVmax-T, SUVmax-N, and SUVmax-M referred to the SUVmax at the primary tumor, cervical lymph nodes, and metastatic lesions respectively. Overall survival (OS) was the primary endpoint. Result Patients who died during the follow-up had significantly higher SUVmax-N, SUVmax-M, and EBV DNA level than those in the patients who were alive. SUVmax-N and SUVmax-M were positively correlated with EBV DNA level. The cut-off values of SUVmax-T, SUVmax-N, SUVmax-M, and EBV DNA were 17.0, 12.7, and 6.9, and 13,800 copies/mL respectively, which were determined by receiver operating characteristic (ROC) curve analysis. Patients with elevated SUVmax-N, SUVmax-M, and EBV DNA levels had a lower 3-year OS rate. In multivariate analysis, the independent prognostic factors of OS included EBV DNA, metastatic site, and locoregional radiotherapy application, while SUVmax was not an independent prognostic factor. Conclusion In de novo metastatic NPC patients, higher SUVmax-N and SUVmax-M were associated with worse prognosis. However, the predictive ability of SUVmax-N and SUVmax-M was poorer than that of EBV DNA.

Purpose To evaluate which patients with nasopharyngeal carcinoma (NPC) obtained the greatest benefits from the detection of distant metastasis with [18F]fluorodeoxyglucose positron emission tomography and computed tomography (PET/CT) combined with plasma Epstein-Barr virus (EBV) DNA levels. Patients and Methods Consecutive patients with NPC were prospectively enrolled. PET/CT, conventional work-up (CWU), and quantification of plasma EBV DNA were performed before treatment. The accuracy of these strategies for distant metastases was assessed. The costs of the diagnostic strategies were compared. Results Eighty-six (14.8%) of the 583 eligible patients were found to have distant metastases; 71 patients (82.6%) by PET/CT and 31 patients (36.0%) by CWU. In the multivariable analysis, advanced N stage (odds ratio, 2.689; 95% CI, 1.894 to 3.818) and pretreatment EBV DNA level (odds ratio, 3.344; 95% CI, 1.825 to 6.126) were significant risk factors for distant metastases. PET/CT was not superior to CWU for detecting distant metastases in very low–risk patients (N0-1 with EBV DNA < 4,000 copies/mL; P = .062), but was superior for the low-risk patients (N0-1 with EBV DNA ≥ 4,000 copies/mL and N2-3 with EBV DNA < 4,000 copies/mL; P = .039) and intermediate-risk patients (N2-3 disease with EBV DNA ≥ 4,000 copies/mL; P < .001). The corresponding patient management changes based on PET/CT were 2.9%, 6.3%, and 16.5%, respectively. The costs per true-positive case detected by PET/CT among these groups were ¥324,138 (≈$47,458), ¥96,907 (≈$14,188), and ¥34,182 (≈$5,005), respectively. Conclusion PET/CT detects more distant metastases than conventional staging in patients with NPC. The largest benefit in terms of cost and patient management was observed in the subgroup with N2-3 disease and EBV DNA ≥ 4,000 copies/mL.

Abstract Background Nasopharyngeal carcinoma (NPC) is closely associated with Epstein-Barr virus (EBV) infection. EBV BamHI A rightward transcripts (BART) encode microRNAs (EBV-miR-BARTs) abnormally highly expressed and play an essential role in NPC. Our previous study indicated that circulating EBV-miR-BARTs was potentially severed as a biomarker of NPC. This study aims to investigate the diagnostic and prognostic performance of miR-BART7-3p and miR-BART13-3p. Methods Plasma levels of EBV DNA, miR-BART7-3p, and miR-BART13-3p were examined by quantitative PCR in 483 treatment-naïve NPC patients and 243 controls without NPC. The prognostic performance was examined by comparing plasma levels with rates of distant metastasis during follow-up. Results Plasma EBV DNA was detected in 93.7% of NPC subjects vs. 8.6% of controls. The microRNAs BART7-3p and miR-BART13-3p were detected in 96.1% and 97.9% of NPC subjects vs. 3.39% and 3.3% of controls. The area under the receiver operating characteristic curve for diagnosing NPC was 0.926 for EBV DNA, 0.964 for miR-BART7-3p, 0.973 for miR-BART13-3p, and 0.997 for all three indices. Among 465 NPC patients without distant metastasis, the above-median miR-BART7-3p and EBV-DNA were independent risk for shorter distant metastasis-free survival (DMFS) (HR=2.94, 95%CI: 1.44-5.97, p=0.003; HR=2.27, 95%CI:1.26-4.10, p=0.006) in multivariate Cox regression. In the 245 patients who received radiotherapy, EBV DNA, miR-BART7-3p, and miR-BART13-3p were detectable immediately afterward in, respectively, 28.6%, 17.6%, and 54.7% of patients. Four-year DMFS rate was lower in patients with detectable miR-BART7-3p (73.0% vs. 89.7%, p<0.001), miR-BART13-3p (61.4% vs. 90.0%, p<0.001), and EBV-DNA (82.7% vs. 89.5%, p=0.035) after radiotherapy. In multivariate Cox regression, detectable miR-BART7-3p and EBV-DNA were independent risks for shorter DMFS (HR=4.13, 95%CI: 1.89-9.01, p<0.001; HR = 2.14, 95%CI: 1.04-4.42, p=0.039). Four-years DMFS rate was 92.0% in subjects (n=156) with neither detectable miR-BART7-3p nor EBV-DNA after radiotherapy, 80.0% in subjects (n=65) with either detectable miR-BART7-3p or EBV-DNA after radiotherapy, and 52.9% in subjects (n=24) with both detectable miR-BART7-3p and EBV-DNA after radiotherapy (p<0.001). Conclusions Circulating levels of miR-BART7-3p and miR-BART13-3p show excellent diagnostic performance for NPC. The combination of plasma levels of miR-BART7-3p and EBV DNA at diagnosis and after radiotherapy may help stratify patients by risk of poor DMFS.
