PURPOSE Cumulative doses of 200 mg/m2 for concurrent cisplatin (DDP) were indicated by retrospective studies as sufficient in conferring survival benefit for locoregionally advanced nasopharyngeal carcinoma (LA-NPC). We performed an open-label, phase II, randomized, controlled trial to test the noninferiority of a two-cycle 100 mg/m2 concurrent DDP regimen over three-cycle in patients with low-risk LA-NPC with pretreatment Epstein-Barr virus DNA levels < 4,000 copies/mL. PATIENTS AND METHODS Eligible patients were randomly assigned 1:1 to receive two cycles or three cycles concurrent DDP-based chemoradiotherapy. The primary end point was 3-year progression-free survival (PFS). The secondary end points included overall survival, distant metastasis-free survival, locoregional relapse-free survival, etc. RESULTS Between September 2016 and October 2018, 332 patients were enrolled, with 166 in each arm. After a median follow-up of 37.7 months, the estimated 3-year PFS rates were 88.0% in the two-cycle group and 90.4% in the three-cycle group, with a difference of 2.4% (95% CI, –4.3 to 9.1, Pnoninferiority = .014). No differences were observed between groups in terms of PFS, overall survival, and the cumulative incidences of locoregional relapse and distant metastasis. Patients in the three-cycle group developed significantly more grade 3-4 mucositis (41 [24.8%] v 25 [15.1%]), hyponatremia (26 [15.8%] v 14 [8.4%]), and dermatitis (9 [5.5%] v 2 [1.2%]). The overall all-grade and grade 3-4 toxicity burdens were heavier in three-cycle group (T-scores, 12.33 v 10.57, P < .001 for all grades; 1.76 v 1.44, P = .05 for grade 3-4). Patients in the three-cycle group also showed more all-grade hearing impairment, dry mouth and skin fibrosis, and impaired long-term quality of life. CONCLUSION Intensity-modulated radiotherapy plus two cycles of concurrent 100 mg/m2 DDP could be an alternative treatment option for patients with low-risk LA-NPC.

PURPOSE: Nasopharyngeal carcinoma (NPC) has been proved to be an Epstein-Barr virus (EBV)-associated cancer. By use of nested polymerase chain reactions (PCRs), we examined whether the presence of EBV DNA in the peripheral-blood cells (PBC) can serve as a prognostic indicator for NPC.PATIENTS AND METHODS: Peripheral blood from 124 patients with NPC who had no evidence of distant metastasis and 114 healthy volunteers with serologically positive findings for EBV infection was collected prospectively. Plasma and erythrocytes were separated. DNA was extracted from PBCs and analyzed by a nested PCR using primers specific to Epstein-Barr virus nuclear antigen 1 (EBNA-1). All patients were treated by radiotherapy with or without chemotherapy. Clinical parameters and status of EBNA-1 in PBCs were used for survival analysis using the Kaplan-Meier method and the Cox proportional hazards model.RESULTS: Positive rates of EBNA-1 DNA in PBCs of NPC patients and healthy volunteers are 71% and 14%, respectively (P = .001). No significant difference was observed with regard to the clinical characteristics of patients who were EBNA-1–positive (n = 88) and those who were EBNA-1–negative (n = 36). After a median follow-up period of 38 months (range, 24 to 56 months), 29 of 88 EBNA-1–positive patients and only one of 36 EBNA-1–negative patients developed distant metastases (P = .00015). Kaplan-Meier estimates of overall survival (P = .0010), metastasis-free survival (P = .0004), and progression-free survival (P = .0004) were significantly lower for the patients in the EBNA-1–positive group than for those in the EBNA-1–negative group. Multivariate Cox analysis confirmed the same results.CONCLUSION: The presence of EBNA-1 DNA in PBCs is a novel, important risk factor for patients with NPC that indicates a significantly higher risk of developing distant metastasis as well as a lower survival rate.

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.

Purpose This multinational study evaluated the antitumor activity of nivolumab in nasopharyngeal carcinoma (NPC). Tumor and plasma-based biomarkers were investigated in an exploratory analysis. Patients and Methods Patients with multiply pretreated recurrent or metastatic NPC were treated with nivolumab until disease progression. The primary end point was objective response rate (ORR) and secondary end points included survival and toxicity. The expression of programmed death-ligand 1 (PD-L1) and human leukocyte antigens A and B in archived tumors and plasma clearance of Epstein-Barr virus DNA were correlated with ORR and survival. Results A total of 44 patients were evaluated and the overall ORR was 20.5% (complete response, n = 1; partial response, n = 8). Nine patients received nivolumab for > 12 months (20%). The 1-year overall survival rate was 59% (95% CI, 44.3% to 78.5%) and 1-year progression-free survival (PFS) rate was 19.3% (95% CI, 10.1% to 37.2%). There was no statistical correlation between ORR and the biomarkers; however, a descriptive analysis showed that the proportion of patients who responded was higher among those with PD-L1 positive tumors (> 1% expression) than those with PD-L1-negative tumors. The loss of expression of one or both human leukocyte antigen class 1 proteins was associated with better PFS than when both proteins were expressed (1-year PFS, 30.9% v 5.6%; log-rank P = .01). There was no association between survival and PD-L1 expression or plasma Epstein-Barr virus DNA clearance. There was no unexpected toxicity to nivolumab. Conclusion Nivolumab has promising activity in NPC and the 1-year overall survival rate compares favorably with historic data in similar populations. Additional evaluation in a randomized setting is warranted. The biomarker results were hypothesis generating and validation in larger cohorts is needed.

The Impact

e13528 Background: Primary CNS lymphoma (PCNSL) incidence is increasing among the elderly and immunocompromised. Especially for these vulnerable populations, a deeper understanding of the prognostic value of tumor biomarkers is necessary to recommend more targeted therapies. Our primary objective is to evaluate the predictive strength of immunohistochemical markers on PCNSL overall survival. Secondary objectives include estimating the impact of these biomarkers on event-free survival. Methods: We retrospectively analyzed PCNSL patients treated at Yale between 2000 and 2018. The primary endpoint is overall survival. Event-free survival, measured by time to relapse or death, is the secondary endpoint. Kaplan-Meier survival curves with log-log confidence intervals were used to estimate survival outcomes. Cox proportional hazards regression models were used to evaluate the statistical significance (at alpha = 0.05) of immunohistochemical markers. Results: One hundred ten subjects were analyzed. Not all biomarkers were available for every subject. The median age of the cohort is 64 years. Sixty-three patients died, and seventy-six experienced an event (progression or death). Surviving patients had a median follow-up of 4.36 years. The median overall survival is 2.63 years (95% confidence interval (CI): 1.13 to 5.98 years). Epstein-Barr virus (EBV) status by immunohistochemistry significantly impacted overall survival. Adjusting for age and immunocompromised status, EBV-positive patients had a higher risk of death than EBV-negative patients (n = 13, hazard ratio (HR) = 33.75, 95% CI: 1.61-708.68). Other significant biomarkers include the GFAP and S100 proteins. The median event-free survival is 1.13 years (95% CI: 0.66 to 2.12 years), and EBV-positive patients had an increased risk of event (HR = 38.23, 95% CI: 2.32-630.88). CD10, BCL2, BCL6, and MUM1 were not significant to predict either survival outcome. Conclusions: We describe a large cohort of PCNSL patients treated at a single institution with comparable survival outcomes to similar research yet conflicting evidence of biomarker significance. Multi-institutional studies may further clarify the prognostic role of immunohistochemistry for improved PCNSL patient survival.

Purpose We investigated the effect of Epstein-Barr virus (EBV) serostatus on the overall outcome of allogeneic hematopoietic stem-cell transplantation (allo-HSCT). Patients and Methods The study included 11,364 patients who underwent allogeneic peripheral-blood or bone marrow transplantation for acute leukemia between 1997 and 2012. We analyzed the impact of donor and recipient EBV serologic status on overall survival, relapse-free survival, relapse incidence, nonrelapse mortality, and incidence of graft-versus-host disease (GVHD) after allo-HSCT. Results Patients receiving grafts from EBV-seropositive donors had the same overall survival as patients who received grafts from EBV-seronegative donors (hazard ratio [HR], 1.05; 95% CI, 0.97 to 1.12; P = .23). Seropositive donors also had no influence on relapse-free survival (HR, 1.04; 95% CI, 0.97 to 1.11; P = 0.31), relapse incidence (HR, 1.03; 95% CI, 0.94 to 1.12; P = .58), and nonrelapse mortality (HR, 1.05; 95% CI, 0.94 to 1.17; P = .37). However, in univariate analysis, recipients receiving grafts from seropositive donors had a higher risk of chronic GVHD than those with seronegative donors (40.8% v 31.0%, respectively; P < .001; HR, 1.42; 95% CI, 1.30 to 1.56). When adjusting for confounders, higher risk was identified for both acute and chronic GVHD. In seronegative patients with seropositive donors, the HR for chronic GVHD was 1.30 (95% CI, 1.06 to 1.59; P = .039). In seropositive patients with seropositive donors, the HR was 1.24 (95% CI, 1.07 to 1.45; P = .016) for acute GVHD and 1.43 (95% CI, 1.23 to 1.67; P < .001) for chronic GVHD. Seropositive patients with seronegative donors did not have an increased risk of GVHD. Conclusion Our data suggest that donor EBV status significantly influences development of acute and chronic GVHD after allo-HSCT.
