Camrelizumab and apatinib plus induction chemotherapy and concurrent chemoradiotherapy in stage N3 nasopharyngeal carcinoma: a phase 2 clinical trial. Nat Commun 2024; 15:1029. [PMID: 38310101 PMCID: PMC10838332 DOI: 10.1038/s41467-024-45126-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Accepted: 01/16/2024] [Indexed: 02/05/2024] Open
Abstract
The antiangiogenic agent apatinib has been shown to clinically improve responses to immune checkpoint inhibitors in several cancer types. Patients with N3 nasopharyngeal carcinoma have a high risk of distant metastasis, however, if the addition of immunotherapy to standard treatment could improve efficacy is unclear. In this phase II clinical trial (ChiCTR2000032317), 49 patients with stage TanyN3M0 nasopharyngeal carcinoma were enrolled and received the combination of three cycles of induction chemotherapy, camrelizumab and apatinib followed by chemoradiotherapy. Here we report on the primary outcome of distant metastasis-free survival and secondary end points of objective response rate, failure-free survival, locoregional recurrence-free survival, overall survival and toxicity profile. After induction therapy, all patients had objective response, including 13 patients (26.5%) with complete response. After a median follow-up of 28.7 months, the primary endpoint of 1-year distant metastasis-free survival was met for the cohort (1-year DMFS rate: 98%). Grade≥3 toxicity appeared in 32 (65.3%) patients, with the most common being mucositis (14[28.6%]) and nausea/vomiting (9[18.4%]). In this work, camrelizumab and apatinib in combination with induction chemotherapy show promising distant metastasis control with acceptable safety profile in patients with stage TanyN3M0 nasopharyngeal carcinoma.

Enhancer remodeling activates NOTCH3 signaling to confer chemoresistance in advanced nasopharyngeal carcinoma. Cell Death Dis 2023; 14:513.

Abstract
Acquired resistance to chemotherapy is one of the major causes of mortality in advanced nasopharyngeal carcinoma (NPC). However, effective strategies are limited and the underlying molecular mechanisms remain elusive. In this study, through transcriptomic profiling analysis of 23 tumor tissues, we found that NOTCH3 was aberrantly highly expressed in chemoresistance NPC patients, with NOTCH3 overexpression being positively associated with poor clinical outcome. Mechanistically, using an established NPC cellular model, we demonstrated that enhancer remodeling driven aberrant hyperactivation of NOTCH3 in chemoresistance NPC. We further showed that NOTCH3 upregulates SLUG to induce chemo-resistance of NPC cells and higher expression of SLUG have poorer prognosis. Genetic or pharmacological perturbation of NOTCH3 conferred chemosensitivity of NPC in vitro and overexpression of NOTCH3 enhanced chemoresistance of NPC in vivo. Together, these data indicated that genome-wide enhancer reprogramming activates NOTCH3 to confer chemoresistance of NPC, suggesting that targeting NOTCH3 may provide a potential therapeutic strategy to effectively treat advanced chemoresistant NPC.

Tumor residue in patients with stage II-IVA nasopharyngeal carcinoma who received intensity-modulated radiation therapy: development and validation of a prediction nomogram integrating postradiotherapy plasma Epstein-Barr virus deoxyribonucleic acid, clinical stage, and radiotherapy dose. BMC Cancer 2023; 23:410. [PMID: 37149594 PMCID: PMC10164328 DOI: 10.1186/s12885-023-10827-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 04/07/2023] [Indexed: 05/08/2023] Open
Abstract
BACKGROUND To develop and validate a predictive nomogram for tumor residue 3-6 months after treatment based on postradiotherapy plasma Epstein-Barr virus (EBV) deoxyribonucleic acid (DNA), clinical stage, and radiotherapy (RT) dose in patients with stage II-IVA nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). METHODS In this retrospective study, 1050 eligible patients with stage II-IVA NPC, who completed curative IMRT and underwent pretreatment and postradiotherapy (-7 to +28 days after IMRT) EBV DNA testing, were enrolled from 2012 to 2017. The prognostic value of the residue was explored using Cox regression analysis in patients (n=1050). A nomogram for predicting tumor residues after 3-6 months was developed using logistic regression analyses in the development cohort (n=736) and validated in an internal cohort (n=314). RESULTS Tumor residue was an independent inferior prognostic factor for 5-year overall survival, progression-free survival, locoregional recurrence-free survival and distant metastasis-free survival (all P<0.001). A prediction nomogram based on postradiotherapy plasma EBV DNA level (0 vs. 1-499 vs. ≥500 copies/ml), clinical stage (II vs. III vs. IVA), and RT dose (68.00-69.96 vs. 70.00-74.00 Gy) estimated the probability of residue development. The nomogram showed better discrimination (area under the curve (AUC): 0.752) than either the clinical stage (0.659) or postradiotherapy EBV DNA level (0.627) alone in the development and validation cohorts (AUC: 0.728). CONCLUSIONS We developed and validated a nomogram model integrating clinical characteristics at the end of IMRT for predicting whether tumor will residue or not after 3-6 months. Thus, high-risk NPC patients who might benefit from immediate additional intervention could be identified by the model, and the probability of residue can be reduced in the future.

The Dynamic Change in Plasma Epstein-Barr Virus DNA Load over a Long-Term Follow-Up Period Predicts Prognosis in Nasopharyngeal Carcinoma. Viruses 2022; 15:66. [PMID: 36680107 PMCID: PMC9865665 DOI: 10.3390/v15010066] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Revised: 12/19/2022] [Accepted: 12/21/2022] [Indexed: 12/28/2022] Open
Abstract
The current study was designed to investigate the changes in the circulating Epstein−Barr virus DNA load (EBV DNA) at various time points before and after treatment and its clinical significance in nasopharyngeal carcinoma (NPC). A total of 142 patients with NPC were prospectively enrolled in this study. The plasma EBV DNA concentration was measured before and after treatment using qPCR. The prognostic values of the EBV DNA load were analyzed using the Kaplan−Meier and Cox regression tests. Following multivariate analysis, our data showed that high pre-EBV DNA loads were associated with significantly poorer distant metastasis free survival (DMFS) and progression free survival (PFS); detectable end-EBV DNA loads were associated with significantly worse loco-regional recurrence free survival (LRRFS) and PFS, and the detecTable 6 months-post-EBV DNA loads were associated with significantly poorer overall survival (OS), DMFS and PFS (p < 0.05). Additionally, combining the pre-EBV DNA load and the stage of the disease, our results showed that patients at stage III-IVA with a low pre-EBV DNA load had similar survival rates as patients at stage II with a low or high pre-EBV DNA load, but had better survival rates than those at stage III-IVA with a high pre-EBV DNA load. Taken together, we showed that the change of the EBV DNA load measured at several time points was more valuable than at any single time point for predicting patients’ survival for NPC. Furthermore, combining the pre-EBV DNA load and the TNM classification could help to formulate an improved prognostic model for this cancer.

Abstract
Background Adding induction chemotherapy to concurrent platinum-based chemoradiotherapy has significantly prolonged the survival time of patients with locoregionally advanced nasopharyngeal carcinoma. In this study, we intend to evaluate the survival outcomes, responses, and incidences of toxicities of induction chemotherapy and the differences between different strategies. Methods A comprehensive search was conducted in PubMed, Embase, Web of Science, and Cochrane CENTRAL on August 10, 2021. Single-arm or multi-arm prospective clinical trials on induction chemotherapy without targeted therapies or immune checkpoint inhibitors were included. Primary outcomes included survival outcomes, objective response rate, and disease control rate, and the secondary outcome was the rates of grade 3 or higher treatment-related adverse events. Results The 39 studies included in the systematic review and meta-analysis comprised 36 clinical trials and 5389 patients. The estimates for 3-year overall and fail-free survival rates were 87% and 77%. The estimates for 5-year rates of overall and fail-free survival were 81% and 73%. Gemcitabine plus platinum and docetaxel combined with 5-fluorouracil plus platinum strategies were associated with the highest rates of 3-year and 5-year overall survival. The objective response and disease control rates were 85% and 98% after the completion of induction chemotherapy. Neutropenia (27%) and nausea/vomiting (7%) were the most common grade 3 or higher treatment-related hematological and non-hematological adverse events during the induction phase. Conclusions Different induction chemotherapeutic strategies appear to have varying effects and risks; a comprehensive summary of the survival outcomes, responses, and toxicities in clinical trials may provide a crucial guide for clinicians.

Prognostic and Predictive Value of Circulating Inflammation Signature in Non-Metastatic Nasopharyngeal Carcinoma: Potential Role for Individualized Induction Chemotherapy.

[PMID: 34079329 PMCID: PMC8164700 DOI: 10.2147/jir.s310017] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Accepted: 04/29/2021] [Indexed: 12/12/2022] Open
Abstract
Purpose We sought to assess the prognostic and predictive value of a circulating inflammation signature (CISIG) and develop CISIG-based tools for predicting prognosis and guiding individualized induction chemotherapy (ICT) in non-metastatic nasopharyngeal carcinoma (NPC). Patients and Methods We retrospectively collected a candidate inflammatory biomarker panel from patients with NPC treated with definitive radiotherapy between 2012 and 2017. We developed the CISIG using candidate biomarkers identified by a least absolute shrinkage and selection operator (LASSO) Cox regression model. The Cox regression analyses were used to evaluate the CISIG prognostic value. A CISIG-based prediction model was constructed, validated, and assessed. Potential stratified ICT treatment effects were examined. Results A total of 1149 patients were analyzed. Nine biomarkers selected by LASSO regression in the training cohort were used to construct the CISIG, including hyaluronidase, laminin, procollagen III, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, high-density lipoprotein, lactate dehydrogenase, and C-reactive protein-to-albumin ratio. CISIG was an independent prognostic factor for disease-free survival (DFS; hazard ratio: 2.65, 95% confidence interval: 1.93–3.64; P < 0.001). High CISIG group (>−0.2) was associated with worse 3-year DFS than low CISIG group in both the training (67.5% vs 88.3%, P < 0.001) and validation cohorts (72.3% vs 85.1%, P < 0.001). We constructed and validated a CISIG-based nomogram, which showed better performance than the clinical stage and Epstein–Barr virus DNA classification methods. A significant interaction between CISIG and the ICT treatment effect was observed (P for interaction = 0.036). Patients with high CISIG values did not benefit from ICT, whereas patients with low CISIG values significantly benefited from ICT. Conclusion The developed CISIG, based on a circulating inflammatory biomarker panel, adds prognostic information for patients with NPC. The proposed CISIG-based tools offer individualized risk estimation to facilitate suitable ICT candidate identification.

Cancer Commun (Lond) 2020; 40:564-585. [PMID: 32989921 PMCID: PMC7668470 DOI: 10.1002/cac2.12100] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Accepted: 09/14/2020] [Indexed: 12/22/2022] Open
Abstract
Nasopharyngeal carcinoma (NPC) is a malignant epithelial tumor ubiquitously associated with the Epstein-Barr virus (EBV), which is highly prevalent in South China, Southeast Asia, and North Africa. Despite being a highly radio-sensitive and treatable cancer, a majority of NPC patients are diagnosed in their advanced stage, and locoregional and distant relapses following definitive treatment contribute largely to cancer-specific mortality among these patients. Given that EBV-driven NPC is the predominant variant seen in endemic regions, various EBV detection methods have been developed and are utilized in screening, prognostication, and post-treatment surveillance of NPC patients. While the Immunoglobulin A (IgA) serology assay is the most extensively studied EBV detection method, the detection of plasma EBV DNA released during replication or cellular apoptosis has shown superior outcomes in endemic population screening, prognostication, and detection of distant relapse. Furthermore, there is emerging evidence on the use of circulating tumor cells, microRNAs, DNA hypermethylation, and combination assays in various clinical scenarios. Herein, this paper provides a comprehensive overview of the relevant studies using various EBV detection techniques in the management of NPC. Specifically, the recent advances, clinical evidence, and challenges associated with the clinical application of EBV liquid biopsies in population screening, prognostication, and surveillance of NPC are presented.

Long-term outcomes and safety after reirradiation in locally recurrent nasopharyngeal carcinoma in a non-endemic area. Strahlenther Onkol 2020; 197:188-197. [PMID: 32514613 DOI: 10.1007/s00066-020-01647-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Accepted: 05/25/2020] [Indexed: 01/22/2023]
Abstract
PURPOSE To determine outcomes and toxicities after reirradiation for locally recurrent nasopharyngeal carcinoma (rNPC) and to apply a prognostic index in a non-endemic region. METHODS We retrospectively reported progression-free survival (PFS), overall survival (OS), and treatment-related toxicities in patients treated with curative intent for locally rNPC. We applied the prognostic model for OS and grade 5 radiotherapy (RT)-related toxicities published by Li et al. and evaluated its prognostic accuracy by receiver operating characteristic (ROC) curve analysis. RESULTS Between 2005 and 2018, 33 patients were treated for rNPC in our institution. Median follow-up was 60 months. The mean time to local recurrence was 75 months. Six (18%) patients had a persistent grade 3 toxicity from a previous RT course. The median re-RT dose was 66 Gy. After re-RT, 13 patients had local failure and 3 patients had metastatic recurrence. Median PFS was 18 months with a 5-year PFS rate of 29%. Median OS was 35 months with a 5-year OS rate of 37%. Grade 3 or higher toxicities rate was 74%. There were 21% grade 5 toxicities. The median time to a grade 5 toxicity was less than 6 months following re-RT. The prognostic nomogram was not predictive for OS or grade 5 toxicities. CONCLUSION Reirradiation of rNPC is an effective treatment but is associated with a high rate of life-threatening toxicity. Stratification of patients based on their risk of developing severe toxicity is needed to select patients who will most likely benefit from re-RT.

Abstract
OBJECTIVE/BACKGROUND To evaluate the efficacy and outcome of adding low-dose fractionated radiotherapy (LDFRT) to induction chemotherapy plus concurrent chemoradiation in locally advanced nasopharyngeal carcinoma (LANPC). METHODS A single-institute, phase II-III, prospectively controlled randomized clinical trial was performed at King Faisal Specialist Hospital and Research Centre. Patients aged 18-70 years with WHO type II and III, stage III-IVB nasopharyngeal carcinoma, Eastern Cooperative Oncology Group performance score of 0-2, with adequate hematological, renal, and hepatic function were eligible. In total, 108 patients were enrolled in this trial. All patients received two cycles of induction docetaxel and cisplatin (75 mg/m2 each) chemotherapy on Days 1 and 22, followed by concurrent chemoradiation therapy. Radiation therapy consisted of 70 Gy in 33 fractions, with concurrent cisplatin 25 mg/m2 for 4 days on Days 43 and 64. Patients were randomly assigned to either adding LDFRT (0.5 Gy twice daily 6 hours apart for 2 days) to induction chemotherapy in the experimental arm (54 patients) or induction chemotherapy alone in the control arm (54 patients). RESULTS There was no significant difference in the post-induction response rates (RRs) or in toxicity between the two treatment arms. The 3-year overall survival (OS), locoregional control (LRC), and distant metastases-free survival (DMFS) rates for experimental arm and control arm were 94% versus 93% (p = .8), 84.8% versus 87.5% (p = .58), and 84.1% versus 91.6% (p = .25), respectively. CONCLUSION The results showed no benefit from adding LDFRT to induction chemotherapy in terms of RR, OS, LRC, and DMFS.

Integrating postradiotherapy plasma Epstein-Barr virus DNA and TNM stage for risk stratification of nasopharyngeal carcinoma to adjuvant therapy. Ann Oncol 2020; 31:769-779. [PMID: 32217076 DOI: 10.1016/j.annonc.2020.03.289] [Citation(s) in RCA: 52] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 02/03/2020] [Accepted: 03/16/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND After curative radiotherapy (RT) or chemoradiation (CRT), there is no validated tool to accurately identify patients for adjuvant therapy in nasopharyngeal carcinoma (NPC). Post-RT circulating plasma Epstein-Barr virus (EBV) DNA can detect minimal residual disease and is associated with recurrence and survival independent of TNM (tumor-lymph node-metastasis) stage. We aimed to develop and validate a risk model for stratification of NPC patients after completion of RT/CRT to observation or adjuvant therapy. PATIENTS AND METHODS The prospective multicenter 0502 EBV DNA screening cohort (Hong Kong NPC Study Group 0502 trial) enrolled from 2006 to 2015 (n = 745) was used for model development. For internal validation, we pooled independent patient cohorts from prospective clinical studies enrolled from 1997 to 2006 (n = 340). For external validation, we used retrospective cohort of NPC patients treated at Sun Yat-sen University Cancer Center from 2009 to 2012 (n = 837). Eligible patients had histologically confirmed NPC of Union for International Cancer Control (UICC) 7th Edition stage II-IVB who completed curative RT/CRT with or without neoadjuvant chemotherapy, had post-RT EBV DNA tested within 120 days after RT and received no adjuvant therapy. The primary end point was overall survival (OS). We used recursive-partitioning analysis (RPA) to classify patients into groups of low, intermediate, and high risk of death. RESULTS Combining post-RT EBV DNA level (0, 1-49, 50-499, and ≥500 copies/ml) and TNM stage (II, III, IVAB), RPA model classified patients into low-, intermediate-, and high-risk groups with 5-year OS of 89.4%, 78.5% and 37.2%, respectively. The RPA low-risk group had comparable OS to TNM stage II (5-year OS 88.5%) but identified more patients (64.8% versus stage II 28.1%) that could potentially be spared adjuvant therapy toxicity. The RPA model (c-index 0.712) showed better risk discrimination than either the TNM stage (0.604) or post-RT EBV DNA alone (0.675) with improved calibration and consistence. These results were validated in both internal and external cohorts. CONCLUSION Combining post-RT EBV DNA and TNM stage improved risk stratification in NPC.

Abstract
Purpose The contribution of adjuvant chemotherapy after chemoradiation therapy (CRT) in nasopharyngeal cancer (NPC) remains controversial. Plasma Epstein-Barr virus (EBV) DNA is a potential biomarker of subclinical residual disease in NPC. In this prospective, multicenter, randomized controlled trial, we used plasma EBV DNA to identify patients with NPC at a higher risk of relapse for adjuvant chemotherapy. Patients and Methods Eligible patients with histologically confirmed NPC of Union for International Cancer Control stage IIB to IVB, adequate organ function, and no locoregional disease or distant metastasis were screened by plasma EBV DNA at 6 to 8 weeks after radiotherapy (RT). Patients with undetectable plasma EBV DNA underwent standard surveillance. Patients with detectable plasma EBV DNA were randomly assigned to either adjuvant chemotherapy with cisplatin and gemcitabine for six cycles (arm 1) or observation (arm 2). Patients were stratified for primary treatment (RT v CRT) and stage (II/III v IV). The primary end point was relapse-free survival (RFS). Results Seven hundred eighty-nine patients underwent EBV DNA screening. Plasma EBV DNA was undetectable in 573 (72.6%) and detectable in 216 (27.4%); 104 (13.2%) with detectable EBV DNA were randomly assigned to arms 1 (n = 52) and 2 (n = 52). After a median follow-up of 6.6 years, no significant difference was found in 5-year RFS rate between arms 1 and 2 (49.3% v 54.7%; P = .75; hazard ratio for relapse or death, 1.09; 95% CI, 0.63 to 1.89). The level of post-RT plasma EBV DNA correlated significantly with the hazards of locoregional failure, distant metastasis, and death. Conclusion In patients with NPC with detectable post-RT plasma EBV DNA, adjuvant chemotherapy with cisplatin and gemcitabine did not improve RFS. Post-RT plasma EBV DNA level should be incorporated as the selection factor in future clinical trials of adjuvant therapy in NPC.

Abstract
Mitochondria play important roles in multiple aspects of viral tumorigenesis. Mitochondrial genomes contribute to the host's genetic background. After viruses enter the cell, they modulate mitochondrial function and thus alter bioenergetics and retrograde signaling pathways. At the same time, mitochondria also regulate and mediate viral oncogenesis. In this context, oncogenesis by oncoviruses like Hepatitis B virus (HBV), Hepatitis C virus (HCV), Human papilloma virus (HPV), Human Immunodeficiency virus (HIV) and Epstein-Barr virus (EBV) will be discussed.

Abstract
Recent studies suggest that plasma Epstein-Barr virus (EBV) DNA may reflect tumor burden in patients with nasopharyngeal cancer. A prospective study was initiated to investigate this correlation in 125 patients (34 pretreatment [Group A], 78 in remission [Group B] and 13 relapsed [Group C]) and 19 healthy controls. In group A, EBV DNA was detected in plasma samples of 24 (70%) patients. In Group B, EBV DNA was detected in 7 patients (range 77–13,731 copies/mL) and further imaging in all but one of these patients revealed active disease confirmed by ultrasound-guided fine-needle biopsy. There was only one false-positive case; this patient is currently under follow-up. Here we describe 2 of the 7 patients with detectable plasma EBV DNA in whom recurrence was documented by PET scan during follow-up. Our results showed that in group B the positive predictive value of quantitative analysis of plasma EBV DNA was 85%. Quantitative analysis of EBV DNA in plasma seems to become an integral part of screening, staging, monitoring, and prediction of relapse in patients with nasopharyngeal carcinoma. However, previous studies cannot be considered definitive and more reports on the use of this technique are urgently needed from both endemic and non-endemic regions.

Abstract
Nasopharyngeal carcinoma (NPC) is very common in southern China and Southeast Asia. In regions where NPC is endemic, undifferentiated subtypes constitute most cases and are invariably associated with Epstein-Barr virus (EBV) infection, whereas the differentiated subtype is more common in other parts of the world. Undifferentiated NPC is a unique malignancy with regard to its epidemiology, etiology, and clinical presentation. Clinically, NPC is highly invasive and metastatic, but sensitive to both chemotherapy and radiotherapy (RT). Overall prognosis has dramatically improved over the past three decades because of advances in management, including the improvement of RT technology, the broader application of chemotherapy, and more accurate disease staging. Despite the excellent local control with modern RT, distant failure remains a challenging problem. Advances in molecular technology have helped to elucidate the molecular pathogenesis of NPC. This article reviews the contribution of EBV gene products to NPC pathogenesis and the current management of NPC.

Abstract
Abstract Treatment modalities of head and neck squamous cell cancer include surgery, radiation, chemotherapy, targeted agents and immune checkpoint inhibition. Treatment is often toxic and can affect long-term function and quality of life. In this context, identification of biomarker data that can help tailor therapy on an individualized basis and reduce treatment-related toxicity would be highly beneficial. A variety of predictive biomarkers have been discovered and are already utilized in clinical practice, while many more are being explored. We will review p16 overexpression as a surrogate biomarker in HPV-associated head and neck cancer and plasma EBV DNA as a biomarker in nasopharyngeal carcinoma, the two established biomarkers currently utilized in clinical practice. We will also examine novel predictive biomarkers that are in clinical development and may shape the future landscape of targeted head and neck cancer therapy. These emerging biomarkers include the tyrosine kinases and their signaling pathway, immune checkpoint biomarkers, tumor suppressor abnormalities, and molecular predictors of hypoxia-targeted therapy. We will also look at futuristic biomarkers including detection of circulating DNA from clinical specimens and rapid tumor profiling. We will highlight the ongoing effort that will see a shift from prognostic to predictive biomarker development in head and neck cancer with the goal of delivering individualized cancer therapy.

Tumor response to neoadjuvant chemotherapy predicts long-term survival outcomes in patients with locoregionally advanced nasopharyngeal carcinoma: A secondary analysis of a randomized phase 3 clinical trial. Cancer 2016; 123:1643-1652. [PMID: 28001301 DOI: 10.1002/cncr.30520] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2016] [Revised: 11/29/2016] [Accepted: 11/30/2016] [Indexed: 11/10/2022]
Abstract
BACKGROUND Tumor response to neoadjuvant chemotherapy using the regimen of cisplatin and 5-fluorouracil could define high-risk patients with locoregionally advanced nasopharyngeal carcinoma (NPC). However, the regimen of docetaxel, cisplatin, and 5-fluorouracil (TPF) appears to be more effective than the regimen of cisplatin and 5-fluorouracil. Therefore, one needs to redefine the high-risk subpopulation of patients receiving neoadjuvant chemotherapy with TPF. METHODS A total of 231 patients from a randomized phase 3 trial with American Joint Committee on Cancer/International Union Against Cancer stage III to stage IVB NPC (except T3-T4N0 disease) who were receiving treatment with the TPF regimen were enrolled. Patient survival rates between different groups were compared. RESULTS Of the 231 patients, the overall response to neoadjuvant chemotherapy was a complete response (CR) for 26 (11.3%), a partial response (PR) for 184 patients (79.6%), and stable disease (SD) for 21 patients (9.1%). Univariate analysis revealed the 3-year failure-free survival (FFS) rates in the CR (88.5% vs 61.9%; P =.017) and PR (81.2% vs 61.9%; P = .01) groups, and the 3-year overall survival rates for the CR (96.2% vs 76.2%; P =.048) and PR (93.4% vs 76.2%; P =.025) groups were obviously higher compared with that of the SD group. In multivariate analysis, CR was established as a favorable prognostic factor for FFS (hazard ratio [HR], 0.210; 95% confidence interval [95% CI], 0.057-0.779 [P =.02]), and PR for FFS (HR, 0.447; 95% CI, 0.213-0.936 [P =.033]) and OS (HR, 0.361; 95% CI, 0.132-0.986 [P =.047]) when compared with SD. No survival difference was observed between the CR and PR groups. CONCLUSIONS Tumor response to TPF may be a properly powerful prognosis predictor and help to develop individualized treatment strategies for patients with locoregionally advanced NPC.

Abstract
Objective Platinum-based chemotherapy in combination with radiotherapy is a standard treatment strategy for locoregionally advanced nasopharyngeal carcinoma (NPC). This study aimed to investigate the long-term efficacy and tolerability of inductive chemotherapy with docetaxel plus carboplatin (TC) or 5-fluorouracil plus carboplatin (FC) followed by concurrent radiation therapy in patients with NPC. Methods Patients (N=88) were randomized to receive TC or FC as inductive therapy followed by concurrent radiotherapy (60–70 Gy) with two cycles of carboplatin (area under the curve =5 mg·h/L). Patients were followed up for 8 years. Primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), toxicity, tumor response, distant metastasis-free survival, and local recurrence-free survival. Results At the end of the follow-up period, 31 patients died, 32 had disease progression, eleven had cancer recurrence, and 25 had distant metastasis. Overall, there was no difference between treatment groups with regard to response or survival. We found that following induction and concurrent chemoradiotherapy, the majority of patients showed a complete response (~96%–98% for induction therapy and 82%–84% for comprehensive therapy) to both therapies. PFS and OS were also similar between groups. The rate of PFS was 63.6% for both FC and TC and that of OS was 65.9% and 63.5%, respectively. The overall incidence of grade 3–4 adverse events in the TC group (20.5%) was higher than in the FC group (10.7%). Neutropenia and leukopenia were the most common grade 3–4 adverse events in the TC group, and mucositis was the most common in the FC group. Conclusion These data indicate that TC and FC therapies have similar efficacy in treating locally advanced NPC and both are well tolerated.

Abstract
Epidemiological trends during the past decade suggest that although incidence of nasopharyngeal carcinoma is gradually declining, even in endemic regions, mortality from the disease has fallen substantially. This finding is probably a result of a combination of lifestyle modification, population screening coupled with better imaging, advances in radiotherapy, and effective systemic agents. In particular, intensity-modulated radiotherapy has driven the improvement in tumour control and reduction in toxic effects in survivors. Clinical use of Epstein-Barr virus (EBV) as a surrogate biomarker in nasopharyngeal carcinoma continues to increase, with quantitative assessment of circulating EBV DNA used for population screening, prognostication, and disease surveillance. Randomised trials are investigating the role of EBV DNA in stratification of patients for treatment intensification and deintensification. Among the exciting developments in nasopharyngeal carcinoma, vascular endothelial growth factor inhibition and novel immunotherapies targeted at immune checkpoint and EBV-specific tumour antigens offer promising alternatives to patients with metastatic disease.

Abstract
Purpose The purpose of this study is to evaluate the prognostic significance of the tumor volume reduction rate (TVRR) measured during adaptive definitive radiation therapy (RT) for nasopharyngeal cancer (NPC). Materials and Methods We reviewed the RT records of 159 NPC patients treated with definitive RT with or without concurrent chemotherapy between January 2006 and February 2013. Adaptive re-planning was performed in all patients at the third week of RT. The pre- and mid-RT gross tumor volumes (GTVs) of the primary tumor and the metastatic lymph nodes were measured and analyzed for prognostic implications. Results After a median follow-up period of 41.5 months (range, 11.2 to 91.8 months) for survivors, there were 43 treatment failures. The overall survival and progression-free survival (PFS) rates at 5 years were 89.6% and 69.7%, respectively. The mean pre-RT GTV, mid-RT GTV, and TVRR were 45.9 cm3 (range, 1.5 to 185.3 cm3), 26.7 cm3 (1.0 to 113.8 cm3), and –41.9% (range, –87% to 78%), respectively. Patients without recurrence had higher TVRR than those with recurrence (44.3% in the no recurrence group vs. 34.0% in the recurrence group, p=0.004), and those with TVRR > 35% achieved a significantly higher rate of PFS at 5 years (79.2% in TVRR > 35% vs. 53.2% in TVRR ≤ 35%; p < 0.001). In multivariate analysis, TVRR was a significant factor affecting PFS (hazard ratio, 2.877; 95% confidence interval, 1.555 to 5.326; p=0.001). Conclusion TVRR proved to be a significant prognostic factor in NPC patients treated with definitive RT, and could be used as a potential indicator for early therapeutic modification during the RT course.

Abstract
This is a prospective randomized trial performed to compare the efficacy of concurrent chemoradiotherapy (CCRT) + S-1 (oral fluoropyrimidine) with that of CCRT + cisplatin in patients with locoregionally advanced nasopharyngeal carcinoma. A total of 105 eligible patients were randomly assigned to receive CCRT with S-1 (S-1 arm, n=50) or cisplatin weekly (control arm, n=55). Patients in the S-1 arm received CCRT plus S-1 (40-60 mg, twice daily for 4 consecutive weeks. Patients in the control arm received standard CCRT with weekly cisplatin. All the patients were included in an intention-to-treat survival analysis. Our results demonstrated that the S-1 and control arms did not differ significantly in terms of complete response, partial response, progression-free survival or overall survival (all P-values >0.05). However, the two arms varied significantly regarding certain grade 3-4 toxicities, including leukopenia, 5.5 vs. 22.0% (P=0.013); mucositis, 20.0 vs. 46.0% (P=0.004); dermatitis, 15.5 vs. 32.7% (P=0.011); and nausea, 9.1 vs. 41.6% (P<0.001) for the S-1 and control arms, respectively. In conclusion, CCRT with S-1 was found to be similar in efficacy but superior in terms of toxicity compared to the standard CCRT with weekly cisplatin.

The challenge of blocking a wider family members of EGFR against head and neck squamous cell carcinomas. Oral Oncol 2015; 51:423-30.

Abstract
Head and neck squamous cell carcinoma (HNSCC) represent 95% of head and neck cancer with an incidence of over half a million people globally. The prognosis for patients with recurrent or metastatic HNSCC is generally poor with low 5-year survival rates despite treatment advances over the past few decades. Consequently, it is essential to search for new biomarkers and effective therapy options to optimize HNSCC treatment. Epidermal growth factor receptor (EGFR) is overexpressed in approximately 90% of tumours. EGFR has become one of most common targets for new therapies being investigated in HNSCC. In this way, multiple therapies targeting EGFR in HNSCC have been tested but response rates are still low especially in the recurrent or metastatic setting. This has been attributed to mechanisms of resistance to EGFR-targeted therapies. Afatinib, an oral small molecule ErbB Family Blocker that irreversibly binds to ErbB1 (EGFR), ErbB2 (HER2) and ErbB4 (HER4), is being investigated in HNSCC treatment with encouraging phase II results and several ongoing phase III trials. Results of these trials will help to understand the place of afatinib in the HNSCC treatment armamentarium.

Abstract
Epstein-Barr virus (EBV) DNA in blood can be quantified in peripheral blood mononuclear cells, in circulating cell-free (CCF) DNA specimens, or in whole blood. CCF viral DNA may be actively released or extruded from viable cells, packaged in virions or passively shed from cells during apoptosis or necrosis. In infectious mononucleosis, viral DNA is detected in each of these kinds of specimens, although it is only transiently detected in CCF specimens. In nasopharyngeal carcinoma, CCF EBV DNA is an established tumor marker. In EBV-associated Hodgkin lymphoma and in EBV-associated extranodal NK-/T-cell lymphoma, there is growing evidence for the utility of CCF DNA as a tumor marker.

Abstract
Head and neck cancer (HNC) broadly includes carcinomas arising from the mucosal epithelia of the head and neck region as well as various cell types of salivary glands and the thyroid. As reflected by the multiple sites and histologies of HNC, the molecular characteristics and clinical outcomes of this disease vary widely. In this Review, we focus on established and emerging biomarkers that are most relevant to nasopharyngeal carcinoma and head and neck squamous-cell carcinoma (HNSCC), which includes primary sites in the oral cavity, oropharynx, hypopharynx and larynx. Applications and limitations of currently established biomarkers are discussed along with examples of successful biomarker development. For emerging biomarkers, preclinical or retrospective data are also described in the context of recently completed comprehensive molecular analyses of HNSCC, which provide a broad genetic landscape and molecular classification beyond histology and clinical characteristics. We will highlight the ongoing effort that will see a shift from prognostic to predictive biomarker development in HNC with the goal of delivering individualized cancer therapy.

Down-regulation of Sp1 suppresses cell proliferation, clonogenicity and the expressions of stem cell markers in nasopharyngeal carcinoma. J Transl Med 2014; 12:222. [PMID: 25099028 PMCID: PMC4132216 DOI: 10.1186/s12967-014-0222-1] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2014] [Accepted: 07/31/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Transcription factor Sp1 is multifaceted, with the ability to function as an oncogene or a tumor suppressor, depending on the cellular context. We previously reported that Sp1 is required for the transcriptional activation of the key oncogenes in nasopharyngeal carcinoma (NPC), including B-lymphoma mouse Moloney leukemia virus insertion region 1 (Bmi1) and centromere protein H (CENPH), but the role of Sp1 and its underlying mechanisms in NPC remained largely unexplored. The objective of this study was to investigate the cellular function of Sp1 and to verify the clinical significance of Sp1 as a potential therapeutic target in NPC. METHODS The levels of Sp1 in the normal primary nasopharyngeal epithelial cells (NPECs) and NPC cell lines were analyzed by Quantitative Real-time RT-PCR (qRT-PCR) and Western blot. The location and expression of Sp1 in the NPC tissues were detected by immunohistochemistry staining (IHC). The effect of Sp1 knockdown on the cell proliferation, clonogenicity, anchorage-independent growth and the stem-cell like phenotype in NPC cells were evaluated by MTT, flow cytometry, clonogenicity analysis and sphere formation assay. RESULTS The mRNA and protein levels of Sp1 were elevated in NPC cell lines than in the normal primary NPECs. Higher expression of Sp1 was found in NPC tissues with advanced clinical stage (P=0.00036). Either inhibition of Sp1 activity by mithramycin A, the FDA-approved chemotherapeutic anticancer drug or Sp1 silencing by two distinct siRNA against Sp1 suppressed the growth of NPC cells. Mechanism analysis revealed that Sp1 silencing may suppress cell proliferation, clonogenicity, anchorage-independent growth and the stem-cell like phenotype through inducing the expression of p27 and p21, and impairing the expressions of the critical stem cell transcription factors (SCTFs), including Bmi1, c-Myc and KLF4 in NPC cells. CONCLUSIONS Sp1 was enriched in advanced NPC tissues and silencing of Sp1 significantly inhibited cell proliferation, clonogenicity, anchorage-independent growth and the stem-cell like phenotype of NPC cells, suggesting Sp1 may serve as an appealing drug target for NPC.

Abstract
BACKGROUND The impact of combining plasma fibrinogen levels with Epstein-Barr Virus DNA (EBV DNA) levels on the prognosis for patients with nasopharyngeal carcinoma (NPC) was evaluated. METHODS In this observational study, 2563 patients with non-metastatic NPC were evaluated for the effects of circulating plasma fibrinogen and EBV DNA levels on disease-free survival (DFS), distant metastasis-free survival (DMFS), and overall survival (OS). RESULTS Compared with the bottom biomarker tertiles, TNM stage-adjusted hazard ratios (HR, 95% confidence intervals (CIs)) for predicting DFS in fibrinogen tertiles 2 to 3 were 1.26 (1.00 to 1.60) and 1.81 (1.45 to 2.26), respectively; HR for EBV DNA tertiles 2 to 3 were 1.49 (1.12 to 1.98) and 4.24 (3.27 to 5.49), respectively. After additional adjustment for established risk factors, both biomarkers were still associated (P for trend <0.001) with reduced DFS (HR: 1.79, 95% CI, 1.43 to 2.25 for top fibrinogen tertiles; HR: 4.04, 95% CI: 3.10 to 5.27 for top EBV DNA tertiles compared with the bottom tertiles). For patients with advanced-stage disease, those with high fibrinogen levels (3.34 g l(-1)) presented with worse DFS, regardless of EBV DNA 4000 or <4000 copies ml(-1) subgroup. Similar findings were observed for DMFS and OS. CONCLUSIONS Circulating fibrinogen and EBV DNA significantly correlate with NPC patients survival. Combined fibrinogen and EBV DNA data lead to improved prognostic prediction in advanced-stage disease.

Abstract
Elevated levels of circulating cell-free Epstein-Barr virus (EBV) DNA have been detected in plasma and serum samples from nasopharyngeal cancer (NPC) patients by quantitative real time PCR (qPCR) test. This qPCR test for circulating EBV DNA was found to be useful in the clinical management of NPC patients. For instance, EBV DNA qPCR test has good sensitivity and specificity in the detection of NPC at disease onset. Increase of the viral DNA load was found in NPC patients at late stages of disease. High EBV DNA load at disease onset or detectable viral load post-treatment was associated with poor survival or frequent relapse in NPC patients. Residual EBV DNA load after primary treatment could be a useful indicator to justify adjuvant chemotherapy. The qPCR test might also be applied to define a poor prognostic group in patients at early stage (I/II) for implementing concurrent chemo-radiotherapy (chemo-RT) to improve patients' outcome. The test is also useful to monitor distant metastases or response to radiotherapy, chemo-RT or surgery. Supplementary tests, however, are needed to pick up EBV negative WHO type I NPC and test improvement is needed to increase sensitivity in detecting stage I disease and local recurrence.

Abstract
OBJECTIVE This study examined prognostic factors in patients with head and neck squamous cell carcinoma with advanced neck disease. STUDY DESIGN The records of 191 patients with previously untreated head and neck squamous cell carcinoma and metastatic cervical lymph node (LN) >6 cm (cN, n = 70) and 3.01 to 6 cm (control, n = 121) in the greatest dimension were reviewed. Univariate and multivariate analyses were used to identify factors associated with disease-free survival (DFS) and locoregional control (LRC). RESULTS In the cN3 group, independent variables for DFS were age, active drinking, LN size, and extranodal extension (P < .05), and that for LRC was age (P = .025). In the control group, independent variables for DFS were tumor location and differentiation and LN bilaterality (P < .05), and that for LRC was LN bilaterality (P = .011). CONCLUSIONS The survival of cN3 patients is affected by host and nodal characteristics including age, drinking, nodal size, and extranodal extension.

Abstract
Purpose To investigate the feasibility of neoadjuvant chemotherapy and replanning intensity-modulated radiotherapy (IMRT) for intracranial invasion nasopharyngeal carcinoma (NPC). Methods and materials From June 2007 to January 2012, 32 patients with intracranial invasion NPC treated with TPF (docetaxel 75 mg/m2, cisplatin 75 mg/m2, 5-FU 2500 mg/m2 every 3 weeks for 3 cycles) neoadjuvant chemotherapy, and replanning IMRT with concurrent chemotherapy were retrospectively studied. The first IMRT plan for each patient was generated based on the original planning CT scan acquired before the start of treatment. Because of tumor shrinkage during radiotherapy, modified gross tumor volume of primary tumor (GTV-P) and high risk clinical target volume (CTV-H), and a new plan was generated and used to complete the course of IMRT. The DVHs of IMRT plan with or without replanning were compared. Results There weren’t statistically significant differences in the V95, D-mean, D-95, and D-99 to the modified PTVGTV-P and PTVCTV-H with and without replanning IMRT. Replanning reduced the doses to the brain stem, optic nerve, optic chiasm and temporal lobe. Objective responses were 100.0% 3 months after completion of radiotherapy. Acute toxicities were well tolerated, except for the relatively high incidence of neutropenia. The 2-year local control rates and distant-metastasis free survival were 88.2% (95% CI, 72.9% to 100.0%) and 89.6% (95% CI, 75.9% to 100.0%). Conclusion Neoadjuvant chemotherapy and replanning IMRT according to tumor shrinkage during the treatment is essential to ensure safe doses to normal tissues, and produces encouraging outcome for intracranial invasion NPC.

Abstract
OBJECTIVES Nasopharyngeal carcinoma is a unique tumour which is endemic in Southern China including Hong Kong. While the treatment results for primary cancer has been encouraging, management of persistent or recurrent tumours has been challenging. Compared to other surgical approaches, the maxillary swing operation provides spacious access to the bilateral nasopharynx and the ipsilateral parapharyngeal space, allowing resection of tumours with wide margins. In this article, we will present our results in the surgical management of recurrent nasopharyngeal carcinoma. MATERIALS AND METHODS Retrospective review. RESULTS Over the years, we have performed salvage maxillary swing nasopharyngectomy for 312 patients. Microscopic negative resection margins were achieved in the majority (79.5%) of the patients. The overall local recurrence rate after surgery was 13.1%, the risk of which was significantly higher in patients with previous positive resection margins. The overall 5-year actuarial local tumour control and overall survival was 74% and 62%, respectively, which was significantly higher in patients with clear resection. For small tumours located in the posterior wall, minimally invasive approach can be used, which included the endoscopic resection, or more recently, the transoral robotic (TORS) assisted approach. CONCLUSION The result of surgical salvage of recurrent nasopharyngeal carcinoma is promising. Every effort should be made to ensure microscopic clearance of disease as well as to minimize the potential complications of surgery that may adversely affect the subsequent quality of life.

Abstract
Neoadjuvant chemotherapy plus radiotherapy is the most common treatment regimen for advanced nasopharyngeal carcinoma (NPC). Whether chronomodulated infusion of chemotherapy can reduce its toxicity is unclear. This study aimed to evaluate the toxic and therapeutic effects of sinusoidal chronomodulated infusion versus flat intermittent infusion of cisplatin (DDP) and 5-fluorouracil (5-FU) followed by radiotherapy in patients with locoregionally advanced NPC. Patients with biopsy-diagnosed untreated stages III and IV NPC (according to the 2002 UICC staging system) were randomized to undergo 2 cycles of sinusoidal chronomodulated infusion (Arm A) or flat intermittent constant rate infusion (Arm B) of DDP and 5-FU followed by radical radiotherapy. Using a “MELODIE” multi-channel programmed pump, the patients were given 12-hour continuous infusions of DDP (20 mg/m2) and 5-FU (750 mg/m2) for 5 days, repeated every 3 weeks for 2 cycles. DDP was administered from 10:00 am to 10:00 pm, and 5-FU was administered from 10:00 pm to 10:00 am each day. Chronomodulated infusion was performed in Arm A, with the peak deliveries of 5-FU at 4:00 am and DDP at 4:00 pm. The patients in Arm B underwent a constant rate of infusion. Radiotherapy was initiated in the fifth week, and both arms were treated with the same radiotherapy techniques and dose fractions. Between June 2004 and June 2006, 125 patients were registered, and 124 were eligible for analysis of response and toxicity. The major toxicity observed during neoadjuvant chemotherapy was neutropenia. The incidence of acute toxicity was similar in both arms. During radiotherapy, the incidence of stomatitis was significantly lower in Arm A than in Arm B (38.1% vs. 59.0%, P = 0.020). No significant differences were observed for other toxicities. The 1-, 3-, and 5-year overall survival rates were 88.9%, 82.4%, and 74.8% for Arm A and 91.8%, 90.2%, and 82.1% for Arm B. The 1-, 3-, and 5-year progression-free survival rates were 91.7%, 88.1%, and 85.2% for Arm A and 100%, 94.5%, and 86.9% for Arm B. The 1-, 3-, and 5-year distant metastasis-free survival rates were 82.5%, 79.1%, and 79.1% for Arm A and 90.2%, 85.2%, and 81.7% for Arm B. Chronochemotherapy significantly reduced stomatitis but was not superior to standard chemotherapy in terms of hematologic toxicities and therapeutic response.

Abstract
PURPOSE To evaluate the feasibility and efficacy of neoadjuvant chemotherapy involving docetaxel and cisplatin followed by intensity-modulated radiotherapy (IMRT) with concurrent cisplatin in patients with newly diagnosed stage III to IVB nasopharyngeal carcinoma (NPC). METHODS Docetaxel (75 mg/m(2) on day 1) and cisplatin (75 mg/m(2) on day 1) were administered on a 3-week cycle for 2 courses, followed by radical IMRT (72 Gy/33F/6.5-7 W) with concurrent cisplatin (75 mg/m(2), on day 1) every 3 weeks for 2 cycles. RESULTS From June 2008 to October 2010, forty-six patients were recruited in this trial. Forty-five patients completed neoadjuvant setting, and all patients completed planned concurrent chemoradiotherapy (CCRT). The complete and partial response rates were 28.3 and 56.5 % after neoadjuvant chemotherapy, and 91.3, 8.7 % after CCRT, respectively. After median follow-up of 26 months (range 12-39 months), one patient experienced local recurrence and 4 patients developed distant metastasis. The 3-year overall survival and progression-free survival rate were 94.1 and 72.7 %, respectively. Neutropenia (37.0 %) and vomiting (28.3 %) were the most common Grade 3-4 adverse effects during neoadjuvant course, while mucositis (30.4 %), xerostomia (30.4 %) and radiodermatitis (21.7 %) were the most common Grades 3 acute toxicities during CCRT. Xerostomia (73.9 %), dysphagia (56.5 %), hear loss (30.4 %) and skin reaction (21.7 %) were the common Grade 1-2 late effects. There were no Grades 3-4 late toxicities. CONCLUSIONS The protocol of neoadjuvant docetaxel and cisplatin followed by IMRT with concurrent cisplatin was well tolerated, with outstanding compliance and efficacy in locally advanced NPC, which deserved further follow-up.

Abstract
PURPOSE Nasopharyngeal carcinoma (NPC) is consistently associated with Epstein-Barr virus (EBV) and highly prevalent in Indonesia. EBV-DNA load can be used for early diagnosis and may have prognostic value. In this study, EBV-DNA load was evaluated in minimal invasive nasopharyngeal (NP) brushings and whole blood for initial diagnosis and therapy assessment against the standard-of-care diagnosis by biopsy with EBV-RISH and standard EBV-IgA serology. EXPERIMENTAL DESIGN NP brushings and blood samples were collected from 289 consecutive ENT patients suspected of NPCs and 53 local healthy controls. EBV-DNA load was quantified by real-time PCR and serology by peptide-based EBV-IgA ELISA. Tissue biopsies were examined by routine histochemistry and by EBER RNA in situ hybridization. RESULTS Repeated NP brushing was well tolerated by patients and revealed high viral load in the 228 NPC cases at diagnosis than 61 non-NPC cancer cases and healthy controls (P < 0.001). The diagnostic value of EBV-DNA load in blood and EBV-IgA serology was inferior to the NP brush results. The level of EBV-DNA load in brushes of patients with NPC was not related to T, N, or M stage, whereas elevated EBV-DNA load in blood correlated with N and M stage. EBV-DNA levels in brushings and whole blood showed a significant reduction at 2 months after treatment (P = 0.001 and P = 0.005, respectively), which was not reflected in EBV-IgA serology. CONCLUSIONS NP brush sampling combined with EBV-DNA load analysis is a minimal invasive and well-tolerated diagnostic procedure, suited for initial diagnosis and follow-up monitoring of NPCs.

Abstract
This study aimed to evaluate the efficacy, toxicity and tolerability of simultaneous modulated accelerated radiation therapy (SMART)-intensity modulated radiotherapy (IMRT) plus cisplatin and 5-fluorouracil (5-FU) chemotherapy for patients with advanced nasopharyngeal cancer (NPC). Forty-five patients with stage II–IV NPC, determined by the American Joint Committee on Cancer system, were treated with prescribed doses of 72 Gy total to the gross tumor volume, 60 Gy to the clinical target volume and metastatic nodal station, and 54 Gy to the clinically-negative neck region. Before radiotherapy, two cycles of cisplatin (30 mg/m2/day on days 1–3) plus 5-FU (400 mg/m2/day on days 1–5) were delivered every three weeks for two cycles. Patients received two cycles of cisplatin (30 mg/m2 day on days 1–3) every three weeks during radiotherapy. In addition, two cycles of cisplatin and 5-FU were given after radiation. All patients completed the prescribed radiotherapy and all scheduled cycles of chemotherapy. Thirty of the 45 patients (66.6%) had a complete response at the end of treatment. Grade 3 mucositis occurred in 4/45 patients (8.8%) and grade 3 dermatitis occurred in 5/45 (11.1%) during radiotherapy. Grade 3 neutropenia occurred in 6/45 (13.3%) during concurrent chemotherapy. There was no treatment-related mortality. After a median follow-up time of 51 months, only three patients’ treatments had failed. Local and distant failure rates were 1.5 and 3.0%, respectively. SMART-IMRT plus cisplatin and 5-FU chemotherapy showed promising activity with manageable toxicity. It is a feasible regimen and improves locoregional disease control.

Abstract
UNLABELLED Treatment options for Epstein-Barr virus (EBV)-associated Burkitt lymphoma in Africa are limited because of chemotherapy-associated toxicity. Since other EBV-associated diseases respond to antiviral agents, we investigated adding an antiviral agent, valacyclovir, to the current chemotherapy regimen in Malawi. In this phase I safety study, we showed that cyclophosphamide combined with valacyclovir was safe. Phase II efficacy trials should now be undertaken. BACKGROUND Nucleoside analogues, including acyclovir, ganciclovir, and their precursors, have shown some efficacy against several Epstein-Barr virus (EBV)-associated diseases, including active EBV infection and posttransplantation lymphoproliferative disorder (PTLD). They have also been proposed as a possible treatment for EBV-associated malignancies, including endemic Burkitt lymphoma. The safety of nucleoside analogues in combination with chemotherapy in the developing world has not been studied and is necessary before any large scale efficacy trials are conducted. PATIENTS AND METHODS Children 3-15 years old meeting inclusion criteria were assigned to a 3+3 dose escalation trial of combination valacyclovir (15 and 30 mg/kg, 3 times daily for 40 days) and cyclophosphamide (CPM) (40 mg/kg day 1, 60 mg/kg on days 8, 18, and 28) or CPM monotherapy. Subjects were monitored for clinical and laboratory toxicity and had EBV levels measured regularly. Dose-limiting toxicity (DLT) was our primary outcome. RESULTS We found that the combination of valacyclovir and CPM was safe and did not lead to any DLT compared with CPM monotherapy. The most common side effects were vomiting, abdominal pain, and tumor site pain, which were similar in both arms. Patients with measurable serum EBV showed decreased loads over their treatment course. CONCLUSIONS We recommend a phase II valacyclovir dose of 30 mg/kg 3 times daily for 40 days. We also observed that 6 of our 12 patients with presumed Burkitt lymphoma had measurable EBV viral loads that decreased over the course of their treatment, suggesting that phase II studies should investigate this correlation further. This study paves the way for a phase II efficacy trial of combined valacyclovir and CPM in the treatment of endemic Burkitt lymphoma.

Abstract
Nasopharyngeal carcinoma (NPC) is a unique malignant head and neck cancer with clinical, demographic, and geographic features distinct from other head and neck epithelial malignancies. Non-keratinizing, poorly differentiated, and undifferentiated WHO types 2 and 3 is the most common subtypes of NPC. NPC is also characterized by its relatively high sensitivity to radiation, so that in the last decades radiotherapy (RT) has been the cornerstone of treatment. However, in the majority of cases NPC is discovered at locally advanced stage. The results are disappointing when RT alone is offered. The 5-year survival rates have been reported to be about 34-52%. The poor prognosis for advanced NPC led to increasing interests in exploring the use of chemotherapy (CT). NPC has been considered to be not only radiosensitive but also chemo-sensitive and has shown high response rate to various chemotherapeutic agents. Certainly, the treatment strategies for NPC will continue to change and evolve as a better understanding is gained of the molecular and immune mechanisms that drive this disease. We reviewed the current literature focusing on the role of CT and new-targeted agents.

Abstract
BACKGROUND We aimed to improve the outcomes for locoregionally advanced nasopharyngeal carcinoma by testing the feasibility and safety of the addition of bevacizumab to chemoradiotherapy. METHODS We enrolled patients older than 18 years with stage IIB-IVB nasopharyngeal carcinoma from 19 centres in North America and Hong Kong. Treatment consisted of three cycles of bevacizumab (15 mg/kg) and cisplatin (100 mg/m(2)) both given on days 1, 22, and 43 of radiation (70 Gy) with intensity-modulated radiation therapy delivered over 33 days on a daily basis, Monday through Friday. Patients then received three cycles of bevacizumab (15 mg/kg) and cisplatin (80 mg/m(2)), both given on days 64, 85, and 106 after radiation, and three cycles of fluorouracil (1000 mg/m(2) per day), given on days 64-67, 85-88, and 106-109 after radiation. The primary endpoint was the occurrence of treatment-related grade 4 haemorrhage or any grade 5 adverse event in the first year. Analyses were done with all eligible patients who started protocol treatment. The trial is registered at ClinicalTrials.gov, number NCT00408694. FINDINGS From Dec 13, 2006, to Feb 5, 2009, we enrolled 46 patients, of whom 44 were eligible for analysis. We recorded no grade 3-4 haemorrhages or grade 5 adverse events; nine patients (20%) had a treatment-related grade 1-2 haemorrhage. Nine patients had one or more grade 4 blood or bone marrow-related complication (grade 4 leucopenia was noted in six patients, grade 4 lymphopenia in five, grade 4 neutrophils in five, and grade 4 anaemia in one). One patient had two grade 4 infections with grade 3-4 neutrophils. One patient reported grade 4 tinnitus, one patient reported grade 4 thrombosis, one reported grade 4 radiation mucositis, and two reported grade 4 pharyngolaryngeal pain. With a median follow-up of 2·5 years (IQR 2·1-2·9), the estimated 2 year locoregional progression-free interval was 83·7% (95% CI 72·6-94·9), the 2 year distant metastasis-free interval was 90·8% (82·2-99·5), the 2 year progression-free survival was 74·7% (61·8-87·6), and 2 year overall survival was 90·9% (82·3-99·4). INTERPRETATION The addition of bevacizumab to standard chemoradiation treatment for patients with nasopharyngeal carcinoma is feasible, and might delay the progression of subclinical distant disease.

Abstract
PURPOSE To determine whether human papillomavirus (HPV) DNA can be detected in the plasma of patients with HPV-positive oropharyngeal carcinoma (OPC) and to monitor its temporal change during radiotherapy. METHODS AND MATERIALS We used polymerase chain reaction to detect HPV DNA in the culture media of HPV-positive SCC90 and VU147T cells and the plasma of SCC90 and HeLa tumor-bearing mice, non-tumor-bearing controls, and those with HPV-negative tumors. We used real-time quantitative polymerase chain reaction to quantify the plasma HPV DNA in 40 HPV-positive OPC, 24 HPV-negative head-and-neck cancer patients and 10 non-cancer volunteers. The tumor HPV status was confirmed by p16(INK4a) staining and HPV16/18 polymerase chain reaction or HPV in situ hybridization. A total of 14 patients had serial plasma samples for HPV DNA quantification during radiotherapy. RESULTS HPV DNA was detectable in the plasma samples of SCC90- and HeLa-bearing mice but not in the controls. It was detected in 65% of the pretreatment plasma samples from HPV-positive OPC patients using E6/7 quantitative polymerase chain reaction. None of the HPV-negative head-and-neck cancer patients or non-cancer controls had detectable HPV DNA. The pretreatment plasma HPV DNA copy number correlated significantly with the nodal metabolic tumor volume (assessed using (18)F-deoxyglucose positron emission tomography). The serial measurements in 14 patients showed a rapid decline in HPV DNA that had become undetectable at radiotherapy completion. In 3 patients, the HPV DNA level had increased to a discernable level at metastasis. CONCLUSIONS Xenograft studies indicated that plasma HPV DNA is released from HPV-positive tumors. Circulating HPV DNA was detectable in most HPV-positive OPC patients. Thus, plasma HPV DNA might be a valuable tool for identifying relapse.

Abstract
BACKGROUND This monocentric study evaluates the activity and tolerability of docetaxel (Taxotere), cisplatin and 5-fluorouracil (5-FU) (TPF) induction chemotherapy followed by intensity-modulated radiotherapy (IMRT) concurrent with high-dose cisplatin in Epstein-Barr virus -related locally advanced undifferentiated nasopharyngeal cancer. PATIENTS AND METHODS We retrospectively reviewed the records of patients who received induction docetaxel 75 mg/m(2) and cisplatin 75 mg/m(2) on day 1, and 5-FU 750 mg/m(2)/day (96-h continuous infusion). Following induction, patients received full doses of IMRT concurrently with cisplatin 100 mg/m(2) every 21 days for three cycles. RESULTS Thirty patients received three TPF cycles (median). Induction was well tolerated; the main toxicity was neutropenia (33%, grade 3-4). During chemoradiotherapy, neutropenia (40%) and mucositis (43%) were the most frequent grade 3-4 adverse events. Mean dose of IMRT was 68.8 Gy. Worst late toxicity was xerostomia. Complete response rate was 93%. At 35 months, two patients had locoregional recurrence, three had distant metastases, and one had both. Three-year progression-free survival and overall survival were 79% [95% confidence interval (CI) 64% to 94%] and 87% (95% CI 74%- to 100%), respectively. CONCLUSIONS In this high-stage nonendemic cancer population, TPF followed by high-dose cisplatin IMRT was promising; this treatment approach deserves evaluation in randomized trials.

Abstract
The benefit achieved by concurrent chemoradiotherapy (CCR) and sequential chemoradiotherapy (SCR) vs radiotherapy (RT) alone for patients with stage II-IVa nasopharyngeal carcinoma (NPC) was compared. A total of 113 patients with stage II-IV a NPC were allotted into CCR group (n=38), SCR group (n=36) and RT alone group (n=39). All patients were irradiated with the same RT technique to ≥66 Gy at 2 Gy per fraction, conventional 5 fractions/week in all groups. The CCR group received concurrent chemotherapy of weekly cisplatin for 7 weeks, and the SCR group received neoadjuvant and (or) adjuvant chemotherapy. The results showed that the 3- and 5-year overall survival rate was significantly higher in CCR group than in RT alone group (92.16% vs 61.54%, 81.58% vs 51.28%, P<0.005). The median survival time was significantly longer in CCR group than in RT alone group (67.8 months vs 52.7 months, P<0.005). It was concluded that CCR could significantly improve overall survival rate, progression-free survival rate, and median survival time when compared with RT alone.

Abstract
BACKGROUND Plasma Epstein-Barr virus (EBV) DNA is widely used in screening, monitoring, and prediction of relapse in nonmetastatic nasopharyngeal carcinoma (NPC). However, data regarding utility of plasma EBV DNA in metastatic NPC are rare. The current study was to test the prognostic implication of plasma EBV DNA level in metastatic/recurrent NPC patients treated with palliative chemotherapy. METHODS Plasma EBV DNA level was measured at baseline and thereafter at the start of each treatment cycle in 127 histologically proven metastatic/recurrent NPC patients treated with palliative chemotherapy. Correlations of pre-treatment and post-treatment plasma EBV DNA levels to survival and response were analyzed. RESULTS Patients with a low pre-treatment plasma EBV DNA level (<median) had significantly better survival than those with a high pre-treatment plasma EBV DNA level (≥median). Patients with a post-treatment plasma EBV DNA decline to an undetectable level had better survival and better tumor response compared with those with a sustained detectable post-treatment plasma EBV DNA level. The early decrease of post-treatment plasma EBV DNA to an undetectable level after 1 cycle of chemotherapy was associated with significantly increased survival. Patients with low pre-treatment plasma EBV DNA level and undetectable post-treatment plasma EBV DNA showed a favorable prognosis (5-year overall and progression-free survival of 50.6% and 21.7%, respectively). CONCLUSIONS Plasma EBV DNA is of predictive value for prognosis in metastatic/recurrent NPC patients undergoing palliative chemotherapy. The pre-treatment plasma EBV DNA level as well as the early decrease of plasma EBV DNA after chemotherapy enabled easy and early discrimination between patients who will and those who will not benefit from continued treatment.
