Cancer Commun (Lond) 2020; 40:32-42. [PMID: 32112522 PMCID: PMC7163789 DOI: 10.1002/cac2.12004] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2019] [Accepted: 12/23/2019] [Indexed: 12/15/2022] Open
Abstract
Background Capecitabine was previously used as a second‐line or salvage therapy for metastatic nasopharyngeal carcinoma (NPC) and has shown satisfactory curative effect as maintenance therapy in other metastatic cancers. This study aimed to explore the role of capecitabine as maintenance therapy in de novo metastatic NPC patients with different plasma Epstein‐Barr virus (EBV) DNA levels before treatment. Methods We selected de novo metastatic NPC patients treated with locoregional radiotherapy (LRRT) for this retrospective study. The propensity score matching (PSM) was applied to balance potential confounders between patients who underwent capecitabine maintenance therapy and those who did not with a ratio of 1:3. Overall survival (OS) was the primary endpoint. The association between capecitabine maintenance therapy and survival was assessed using the log‐rank test and a Cox proportional hazard model. Results Among all patients eligible for this study, 64 received capecitabine maintenance therapy after LRRT. After PSM, 192 patients were identified in the non‐maintenance group. In the matched cohort, patients treated with capecitabine achieved a higher 3‐year OS rate compared with patients in the non‐maintenance group (68.5% vs. 61.8%, P = 0.037). Multivariate analysis demonstrated that capecitabine maintenance therapy was an independent prognostic factor. In subgroup analysis, 3‐year OS rate was comparable between the maintenance and non‐maintenance groups in patients with high pretreatment EBV DNA levels (˃30,000 copies/mL) (54.8% vs. 45.8%, P = 0.835), whereas patients with low pretreatment EBV DNA levels (≤30,000 copies/mL) could benefit from capecitabine maintenance therapy in OS (90.0% vs. 68.1%, P = 0.003). Conclusion Capecitabine maintenance therapy may be superior to non‐maintenance therapy in prolonging OS for de novo metastatic NPC patients with pretreatment EBV DNA ≤ 30,000 copies/mL.

Comparing three induction chemotherapy regimens for patients with locoregionally advanced nasopharyngeal carcinoma based on TNM stage and plasma Epstein-Barr virus DNA level. BMC Cancer 2020; 20:89. [PMID: 32013967 PMCID: PMC6998839 DOI: 10.1186/s12885-020-6555-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Accepted: 01/20/2020] [Indexed: 12/28/2022] Open
Abstract
Background We compared the efficacy and toxicity of three IC regimens (TPF: taxanes, cisplatin, and 5-fluorouracil; TP: taxanes and cisplatin; and PF: cisplatin and 5-fluorouracil) followed by CCRT in locoregionally advanced NPC. Methods The retrospective study involved 1354 patients with newly diagnosed stage III-IVA NPC treated with IC and CCRT. The median follow-up time in our cohort was 50 months. Based on EBV DNA level, all the patients with stage IV were divided into low- (pre-EBV DNA < 1500 copies) and high-risk group (pre-EBV DNA ≥ 1500 copies). Progression free survival (PFS), overall survival (OS), locoregional relapse free survival (LRFS), distant metastasis free survival (DMFS) and grade 3–4 toxicities were compared among different IC regimens. The survival rates were compared using log-rank test and a Cox proportional hazards model was used to perform multivariate analyses. Results A multivariate analysis revealed TPF to be more effective than TP. Among stage III patients, no significant difference in clinical outcome between the different IC regimens was showed, while TPF was associated with significantly better survival conditions in the stage IV patients. A further subgroup analysis revealed that only patients with pre-EBV DNA ≥ 1500 copies could benefit from the application of TPF among stage IV NPC. In terms of acute toxicities, PF was associated with fewer grade 3/4 acute toxicities. Conclusions In low-risk NPC patients, PF-based IC showed similar efficacy as TPF and TP but was associated with fewer grade 3/4 acute toxicities. In high-risk patients, however, the TPF regimen was superior to PF and TP, although grade 3/4 toxicities were more common with the TPF regimen.

Maximal standard uptake values of 18F-fluoro-2-deoxy-D-glucose positron emission tomography compared with Epstein-Barr virus DNA as prognostic indicators in de novo metastatic nasopharyngeal carcinoma patients. BMC Cancer 2019; 19:908. [PMID: 31511059 PMCID: PMC6740035 DOI: 10.1186/s12885-019-6106-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Accepted: 08/29/2019] [Indexed: 11/28/2022] Open
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.

Abstract
Objective We aimed to investigate the efficacy and safety of cetuximab (CTX) or nimotuzumab (NTZ) on the addition of palliative chemotherapy (PCT) in patients with de novo metastatic nasopharyngeal carcinoma (NPC). Materials and methods From 2007 to 2016, 451 eligible patients with de novo metastatic NPC were enrolled in the study. With propensity score matching technique, we created a well-balanced cohort by matching patients who received CTX/NTZ plus PCT (62 patients) with those receiving PCT alone (248 patients) in a ratio of 1:4. The primary endpoint was overall survival (OS). All potential prognostic factors were involved in the multivariate analysis with the Cox regression hazards model. Kaplan-Meier curves were used to compare the survival status, and log-rank test to measure the significance. Results The median follow-up time was 27.7 months (range, 1-126 months). No significant difference in survival was observed between the CTX/NTZ plus PCT group and PCT group. (3-year OS: 63.0% vs 58.1%; P=0.485). The administration of CTX/NTZ was not found to be an independent prognostic factor in multivariate analysis. With regard to toxicity, the development of a G3-4 skin reaction and mucositis was more common in patients receiving CTX plus PCT. Interaction effects analysis did not show any significant interaction effects on OS between the treatment regimen and prognostic factors (P>0.05). Conclusion The efficacy of CTX/NTZ and PCT is comparable to single PCT treatment in terms of survival outcomes among de novo metastatic NPC patients. Moreover, the application of CTX exacerbated skin reactions and mucositis.

The impact of Adult Comorbidity Evaluation-27 on the clinical outcome of elderly nasopharyngeal carcinoma patients treated with chemoradiotherapy or radiotherapy: a matched cohort analysis. J Cancer 2019; 10:5614-5621.

Abstract
Objectives: To evaluate the prognostic significance of Adult Comorbidity Evaluation-27 (ACE-27) for elderly patients (age ≥70 years) with locoregionally advanced nasopharyngeal carcinoma (NPC) treated with Intensity-Modulated Radiotherapy (IMRT), with or without chemotherapy. Methods: 206 elderly patients with locoregionally advanced NPC treated from December 2006 to December 2016 were involved into analysis as the training cohort. Besides, a separate cohort of 72 patients from the same cancer center collected between January 2003 and October 2006 served as the validation cohort. By using propensity score matching (PSM), we created a balanced cohort by matching patients who received chemoradiotherapy with patients who received IMRT alone. Treatment toxicities were calculated between CRT and RT groups using the χ2 test. The primary endpoint was cancer-specific survival (CSS). Multivariate analysis was performed to assess the relative risk for each factor by using a Cox's proportional hazards regression model. Results: The median follow-up was 39.0 months (range = 3-137 months). In the PSM cohort, patients in the CRT group achieved comparable survival compared with patients in the RT group. The 3-year CSS rate was 64.3% and 65.2%, respectively (P =0.764). In multivariate analysis, the addition of chemotherapy to IMRT was not an independent prognostic factor for CSS, whereas a high ACE-27 score was an independent risk factor. In subgroup analysis with ACE-27 score ≥ 2, the 3-year CSS rate was worse in patients from the CRT group (63.5% vs. 46.3%, P = 0.041). Conclusions: CRT is comparable to IMRT alone for elderly patients with locoregionally advanced NPC. The ACE-27 tool may help to identify high-risk subgroup for poor disease outcome and tailor individualized treatment.

Abstract
OBJECTIVE We aimed to investigate whether zoledronic acid (ZA) can prevent skeletal-related events (SREs) and offer survival benefits for nasopharyngeal carcinoma (NPC) patients with bone-only metastasis at diagnosis. MATERIALS AND METHODS A total of 228 newly diagnosed NPC cases with bone-only metastasis were eligible for this retrospective study. Using the propensity score method (PSM) method, a well-balanced cohort was created for further analysis. Overall survival (OS) was the primary endpoint. The difference in survival was evaluated using the log-rank test. Hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause mortality were derived from a Cox regression model. Cumulative incidence competing risk analyses using Fine and Gray's method was used to test the cumulative incidence of SREs between the different treatment groups. RESULT In the PSM cohorts, patients in the platinum-based palliative chemotherapy (PCT) + ZA group and PCT alone group achieved similar 3-year OS (57.3% vs. 46.4%; log rank P = 0.188). Multivariate analysis indicated that ZA administration was not an independent prognostic factor (HR, 0.783; 95% CI, 0.267-2.300; P = 0.657). There was no significant difference in acute treatment toxicity between the 2 treatment groups, although the cumulative incidence of bone-related events (SREs) was significantly lower in the PCT + ZA group (Fine-Gray P = 0.026). CONCLUSION ZA combined with PCT could not improve OS in NPC patients with bone-only metastasis at diagnosis. However, the incidence of SREs could be effectively prevented via ZA application.

Abstract
Objective: This study aimed to establish a nomogram to predict the risk of post-radiation necrosis in nasopharyngeal carcinoma (NPC) patients. Background: This study was performed to identify influencing factors for developing post-radiation necrosis, and to establish an effective nomogram model to predict individual risks in NPC patients. Methods: 7144 NPC patients receiving radical radiotherapy from 2007 to 2012 were involved in the study, and 207 of them developed nasopharyngeal necrosis (NPN). The clinical characteristics and baseline laboratory results were collected and analyzed. Independent predictive factors were selected using the Cox proportional model and incorporated into the nomogram. The receiver operating characteristic curve and the calibration curve were used to verify discrimination and calibration. Results: The experience of re-irradiation contributed most to the occurrence of NPN (HR, 15.56, 95% CI 10.84–22.35, p<0.001). Clinical factors including age, pathology type, history of diabetes, and original T stage were independent predictors of NPN. Factors reflecting patients’ baseline nutritional and inflammatory status such as hemoglobin, albumin, and C-reactive protein were also significantly associated with the development of NPN. With all independent predictive factors incorporated, a nomogram was generated, and it showed excellent discrimination and calibration. Conclusion: This study was the first large-scale cohort study focusing on the development of NPN and established a nomogram to predict its occurrence based on the clinical and laboratory indicators. The nomogram demonstrated good discriminative capacity and satisfactory agreement, which would offer valuable clues for clinicians to distinguish the high-risk NPN population and maintain close surveillance.

Abstract
Object To ascertain the treatment effect of concurrent chemotherapy (CCT) in stage II‐III nasopharyngeal carcinoma (NPC) patients with different Epstein‐Barr virus (EBV) DNA level in intensity‐modulated radiotherapy (IMRT) era. Methods A total of 2742 patients diagnosed with stage II‐III NPC were involved in this study. Patients received IMRT with/without CCT. Overall survival (OS) was the primary endpoint. Receiver operating characteristics curve was used to determine the cut‐off value of pre‐DNA based on OS. After propensity score matching, the role of CCT was explored in patients with different EBV DNA level. Results In our cohort, the cut‐off value of pre EBV DNA was 1460 copies/mL (area under curve [AUC], 0.695‐0.769; sensitivity, 0.766; specificity, 0.599). Patients with high EBV DNA level showed poor survival in OS, progression free survival (PFS), locoregional relapse‐free survival (LRFS) and distant metastasis‐free survival (DMFS). In patients with EBV DNA level >1460 copies/mL, the concurrent chemoradiotherapy (CCRT) group achieved higher 3‐year OS compared with IMRT groups. However, the CCRT and IMRT groups showed comparable OS in patients with EBV DNA ≤1460 copies/mL. In multivariate analyses, CCT was a protective factor for OS, PFS, and LRFS in high‐risk patients (EBV DNA level >1460 copies/mL), while not an independent prognostic factor among the low‐risk patients (EBV DNA level ≤1460 copies/mL). Conclusion Pre‐EBV DNA could be a useful tool to guide individualized treatment for stage II‐III NPC patients. Additional CCT to IMRT improved the survival for patients with high pre‐EBV DNA, while those with low pre‐EBV DNA could not.

Abstract
Background: The goal of this study was to explore the value of adding neoadjuvant chemotherapy (NACT) or adjuvant chemotherapy (ACT) to concurrent chemoradiotherapy (CCRT) in patients with nasopharyngeal carcinoma (NPC) with different risks of treatment failure. Patients and Methods: A total of 2,263 eligible patients with stage III–IVb NPC treated with CCRT ± NACT or ACT were included in this retrospective study. Distant metastasis–free survival (DMFS), overall survival, and progression-free survival were calculated using the Kaplan-Meier method and differences were compared using the log-rank test. Results: Patients in the low-risk group (stage N0–1 disease and Epstein-Barr virus [EBV] DNA <4,000 copies/mL) who received NACT followed by CCRT achieved significantly better 5-year DMFS than those treated with CCRT alone (96.2% vs 91.3%; P= .008). Multivariate analyses also demonstrated that additional NACT was the only independent prognostic factor for DMFS (hazard ratio, 0.42; 95% CI, 0.22–0.80; P=.009). In both the intermediate-risk group (stage N0–1 disease and EBV DNA ≥4,000 copies/mL and stage N2–3 disease and EBV DNA <4,000 copies/mL) and the high-risk group (stage N2–3 disease and EBV DNA ≥4,000 copies/mL), comparison of NACT or ACT + CCRT versus CCRT alone indicated no significantly better survival for all end points. Conclusions: The addition of NACT to CCRT could reduce distant failure in patients with low risk of treatment failure.

Abstract
BACKGROUND AND PURPOSE No nomogram has been established for de novo metastatic NPC patients previously. Thus, we retrospectively involved 502 de novo NPC patients to develop a practical clinical tool by combining prognostic biomarkers to estimate individual risk. METHODS The nomogram was based on a primary cohort involving 353 patients from 2007 to 2013; all independent prognostic factors were integrated for inclusion in the model. The predictive accuracy of the model was evaluated by concordance index (C-index). A calibration curve was used to compare predicted and observed survival. We confirmed the results using a validation cohort study on 149 patients enrolled from 2014 to 2016. RESULTS Five independent prognostic factors derived from multivariable analysis were entered into the nomogram. The C-index of the nomogram was 0.724. The calibration curves for probability of 3- and 5-year overall survival (OS) showed satisfactory agreement between predicted survival and actual observed survival. The Kaplan-Meier survival curves showed a significant difference in survival among different risk groups according to the total score. All results were confirmed in the validation cohort. CONCLUSION We established a convenient nomogram that provides individual prediction of OS for patients with de novo metastatic NPC.

Abstract
Background Currently, the diagnosis and treatment of nasopharyngeal carcinoma (NPC) patients with residual cervical lymphadenopathy following radical radiotherapy with or without chemotherapy are challenging. We investigated the prognosis of NPC patients with residual cervical lymphadenopathy and assessed the diagnostic and prognostic values of Epstein-Barr virus (EBV) DNA in these patients. Methods This study included 82 NPC patients who were diagnosed with suspected residual cervical lymphadenopathy following completion of antitumor therapy. Their plasma EBV DNA levels were measured using quantitative polymerase chain reaction (qPCR) before the initiation of treatment and before neck dissection. Fine needle aspiration cytology (FNAC) was performed in 21 patients. All patients had undergone neck dissection and postoperative pathological examination to identify the nature of residual cervical lymphadenopathy. The overall survival (OS), progression-free survival (PFS), distant metastasis-free survival (DMFS), and locoregional relapse-free survival (LRRFS) were calculated using the Kaplan–Meier method and compared using the log-rank test. The Cox proportional hazards model was used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). Multivariable analysis was used to estimate the effect of potential prognostic factors on survival. Results Following a median follow-up of 52.6 months, compared with patients with negative postoperative pathological findings for residual cervical lymphadenopathy, the patients with positive findings had a significantly lower 3-year PFS rate (49.9% vs. 83.3%, P = 0.008). Among NPC patients with residual cervical lymphadenopathy, the patients with preoperative plasma EBV DNA > 0 copy/mL had a lower 3-year PFS rate than did those with no detectable EBV DNA (43.7% vs. 61.1%, P = 0.031). In addition, combining FNAC with preoperative EBV DNA detection improved the diagnostic sensitivity. Multivariable analysis demonstrated that residual cervical lymphadenopathy with positive postoperative pathological result was an independent prognostic factor for PFS and that detectable preoperative plasma EBV DNA was an independent prognostic factor for OS. Conclusions Using FNAC combined with preoperative EBV DNA detection improves the sensitivity in diagnosing NPC with residual cervical lymphadenopathy. Compared with patients with undetectable EBV DNA, patients with detectable preoperative plasma EBV DNA have worse prognosis and may require a more aggressive treatment strategy.

Patterns of Failure and Survival Trends in 3,808 Patients with Stage II Nasopharyngeal Carcinoma Diagnosed from 1990 to 2012: A Large-Scale Retrospective Cohort Study. Cancer Res Treat 2019; 51:1449-1463. [PMID: 30913870 PMCID: PMC6790851 DOI: 10.4143/crt.2018.688] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Accepted: 03/06/2019] [Indexed: 11/21/2022] Open
Abstract
Purpose The purpose of this study was to investigate the survival trends and patterns of failure in patients with stage II nasopharyngeal carcinoma (NPC) treated with radiotherapy (RT) and chemotherapy over the last 20 years. Materials and Methods Thirty-eight hundred and eight patients diagnosed with stage II NPC between January 1990 and December 2012 were involved in this retrospective cohort study. All patients were treated with RT. According to the main imaging techniques and RT technology, we categorized these patients into four calendar periods: 1990-1996, 1997-2002, 2003-2007, and 2008-2012. Overall survival (OS), progression-free survival (PFS), locoregional relapse-free survival (LRFS), and distant metastasis–free survival (DMFS) were served as the clinical outcome. Results After a median follow-up period of 84.7 months, we observed increasing trends in survival and disease control. The 3- and 5-year OS rates increased from 87.1% and 78.7% in the first calendar period to 97.4% and 94.5% in the last calendar period, respectively (p<0.001). Additionally, significant increasing trends could be seen in the PFS and LRFS during the four calendar periods. In the subgroup analysis, the LRFS in patients older than 50 years at diagnosis showed greater improvement than younger patients. However, the rate of distant metastasis was stable and relatively low, as the 5-year DMFS ranged from 90.5% to 94.7% among the four calendar periods. Conclusion The survival rates in patients with stage II NPC showed increasing trends from 1990 to 2012. The advance of RT provided excellent locoregional control and enhanced OS.

Ten-year outcomes of survival and toxicity for a phase III randomised trial of concurrent chemoradiotherapy versus radiotherapy alone in stage II nasopharyngeal carcinoma. Eur J Cancer 2019; 110:24-31. [PMID: 30739837 DOI: 10.1016/j.ejca.2018.10.020] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2018] [Revised: 10/13/2018] [Accepted: 10/23/2018] [Indexed: 10/27/2022]
Abstract
PURPOSE Our previous results showed survival benefits of concurrent chemoradiotherapy (CCRT) in treating stage II nasopharyngeal carcinoma (NPC) compared with radiotherapy (RT) alone. Here, we present the updated 10-year survival results and late toxicity profile to assess the ultimate effectiveness of concurrent chemotherapy. METHODS Patients with stage II NPC were randomly assigned to RT arm (n = 114) or to CCRT arm (n = 116) with a concurrent weekly cisplatin regimen. The primary end-point was overall survival (OS). RESULTS With a median follow-up of 125 months, significant improvements in OS (83.6% vs 65.8%, P = 0.001), progression-free survival (76.7% vs 64.0%, P = 0.014), cancer-specific survival (86.2% vs 71.9%, P = 0.002), distant-metastasis free survival (94.0% vs 83.3%, P = 0.007) were observed in CCRT arm. In point of locoregional-relapse free survival, the impact of CCRT was not remarkable. The findings were in accordance with our previous report. The survival benefits earned by CCRT mainly reflected in T2N1 population. Although CCRT brought more acute toxic effects (P = 0.001), as presented in previous report, the late toxicities and treatment-associated deaths events were comparable between two arms. CONCLUSIONS Ten-year outcomes confirmed that CCRT could improve the OS of stage II patients without adding late toxicities compared with conventional RT.

Identifying optimal candidates for local treatment of the primary tumor among patients with de novo metastatic nasopharyngeal carcinoma: a retrospective cohort study based on Epstein-Barr virus DNA level and tumor response to palliative chemotherapy. BMC Cancer 2019; 19:92. [PMID: 30665378 PMCID: PMC6341516 DOI: 10.1186/s12885-019-5281-5] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Accepted: 01/07/2019] [Indexed: 11/30/2022] Open
Abstract
Background To evaluate the clinical outcome in patients with de novo metastatic nasopharyngeal carcinoma (NPC) treated or not treated with locoregional radiotherapy (LRRT) based on plasma Epstein–Barr virus (EBV) DNA level and tumor response after palliative chemotherapy (PCT). Methods From 2007 to 2016, 502 patients with de novo metastatic NPC were included in this study. All patients were treated with PCT and 315 patients received LRRT. Our primary study endpoint was overall survival (OS). Results EBV DNA was detected in 461 patients (91.8%) before treatment but was undetectable in 249 patients (49.6%) after PCT. Three hundred and seventeen patients (63.1%) achieved satisfactory response (complete response or partial response) to PCT. Both the post-PCT EBV DNA level and tumor response were independent prognostic factors. Among low-risk patients (patients with undetectable EBV DNA and satisfactory tumor response after PCT), the 3-year OS rate was 80.4% in LRRT-treated patients and 45.3% in patients not treated with LRRT (P < 0.001). Multivariate analyses demonstrated that LRRT was an independent prognostic factor of OS in the low-risk patients (P < 0.001). However, among the high-risk patients (patients with detectable EBV DNA and/or unsatisfactory response after PCT), no statistically significant survival differences were observed between the LRRT and non-LRRT groups. Conclusions EBV DNA level and tumor response after PCT both correlate with the prognosis of de novo metastatic NPC. In such cases, LRRT may benefit the patients with undetectable EBV DNA levels and satisfactory tumor response after PCT.

Abstract
Purpose The purpose of this study was to subdivide M1 stage nasopharyngeal carcinoma (NPC) patients with bone-only metastases for prognosis prediction while identifying the treatment effect of locoregional radiotherapy (LRRT) and metastasis radiotherapy (MRT) among patients with different risk. Materials and Methods From November 2006 to October 2016, a total of 226 patients with bone-only metastasic NPC were retrospectively enrolled. All patients developed distant lesions before receiving treatment. All potential prognostic factors were considered and the correlation of the M1 subdivisions with overall survival (OS) was determined by Cox regression hazards model. Kaplan–Meier curves were used to appraise survival condition and log-rank testing was used to compare the differences. Results The median follow-up time was 33.9 months (range, 3 to 126 months). According to multivariate Cox proportional hazard analysis, the number of metastatic lesions and Epstein-Barr virus (EBV) DNA status after palliative chemotherapy (PCT) were independent prognostic factors for OS. Thus, we subdivided patients into three risk groups according to these two factors. Systemic chemotherapy combined with LRRT may benefit patients in low- and intermediate-risk groups but not in the high-risk group. Further aggressive MRT based on systemic chemotherapy showed no survival benefit in any risk group. Conclusion The stratification of NPC patients with bone-only metastasis based on EBV DNA after PCT and the number of metastatic lesions provided promising prognostic value and could aid clinicians in person-specific treatment.

Symptomatic venous thromboembolism associated with peripherally inserted central catheters predicts a worse survival in nasopharyngeal carcinoma: results of a large cohort, propensity score-matched analysis. BMC Cancer 2018; 18:1297. [PMID: 30594171 PMCID: PMC6310996 DOI: 10.1186/s12885-018-5213-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2018] [Accepted: 12/12/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Despite increasing use, symptomatic venous thromboembolism (VTE) associated with peripherally inserted central catheter (PICC) is a common complication in nonmetastatic nasopharyngeal carcinoma (NPC) patients. METHODS A total of 3012 nonmetastatic NPC patients were enrolled in this retrospective study, and we applied Cox regression and log-rank tests to assess the association between PICC-VTE and survival using the propensity score method (PSM) to adjust for gender, age, radiotherapy technique, tumor stage, node stage, UICC clinical stage and pre-treatment EBV DNA. RESULTS 217 patients developed PICC-VTE, with an incidence of 7.20%. PSM identified 213 patients in the cohort with VTE and 852 in that without. Patients who developed PICC-VTE had a shorter 5-year PFS (77.5% vs 87.6%, p < 0.001), DMFS (85.0% vs 91.2%, p < 0.001), LRRFS (93.9% vs 97.7%, p < 0.001) and OS (85.4% vs 87.6%, p < 0.001). Subgroup analyses indicated that no significant survival difference was found between PICC-related superficial venous thrombosis and deep vein thrombosis, nor did different anticoagulant treatment methods. CONCLUSIONS PICC-VTE was associated with a worse survival outcome in nonmetastatic NPC patients. A prospective randomized clinical trial is required to verify the results.

Abstract
Background We wished to evaluate the efficacy and safety of liposomal paclitaxel and docetaxel for induction chemotherapy (IC) for nasopharyngeal carcinoma (NPC). Methods A total of 1498 patients with newly-diagnosed NPC between 2009 and 2017 treated with IC plus concurrent chemotherapy were included in our observational study. Overall survival (OS), progression-free survival (PFS), locoregional relapse-free survival (LRFS), distant metastasis-free survival (DMFS) and grade-3–4 toxicities were compared between groups using propensity score matching (PSM). Results In total, 767 patients were eligible for this study, with 104 (13.6%) and 663 (86.4%) receiving a liposomal paclitaxel-based and docetaxel-based taxanes, cisplatin and 5-fluorouracil (TPF) regimen, respectively. PSM identified 103 patients in the liposomal-paclitaxel group and 287 patients in the docetaxel group. There was no significant difference at 3 years for OS (92.2% vs. 93.9%, P = 0.942), PFS (82.6% vs. 81.7%, P = 0.394), LRFS (94.7% vs. 93.3%, P = 0.981) or DMFS (84.6% vs. 87.4%, P = 0.371) between the two groups after PSM. Significant interactions were not observed between the effect of chemotherapy regimen and sex, age, T stage, N stage, overall stage, or Epstein–Barr virus DNA level in the subgroup multivariate analysis. The prevalence of grade-3–4 leukopenia and neutropenia in the liposomal-paclitaxel group was significantly lower than that of the docetaxel group (P < 0.05 for all). Conclusions Compared with docetaxel, liposomal paclitaxel has identical anti-tumor efficacy, but causes fewer and milder adverse reactions in IC for NPC.

Famitinib in combination with concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma: a phase 1, open-label, dose-escalation Study. Cancer Commun (Lond) 2018; 38:66. [PMID: 30382933 PMCID: PMC6235389 DOI: 10.1186/s40880-018-0330-z] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2018] [Accepted: 09/15/2018] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Famitinib is a tyrosine kinase inhibitor against multiple targets, including vascular endothelial growth factor receptor 2/3, platelet-derived growth factor receptor, and stem cell factor receptor (c-kit). Previous studies have demonstrated anti-tumour activities of famitinib against a wide variety of advanced-stage solid cancers. We aimed to determine the safety and efficacy of famitinib with concurrent chemoradiotherapy (CCRT) in patients with locoregionally advanced nasopharyngeal carcinoma (NPC). We also evaluated the feasibility of contrast-enhanced ultrasound (D-CEUS) as a predictor of early tumour response to famitinib and to correlate functional parameters with clinical efficacy. METHODS The trial was conducted in subjects with stage III or IVa-b NPC using a 3 + 3 design of escalating famitinib doses. Briefly, subjects received 2 weeks of famitinib monotherapy followed by 7 weeks of famitinib plus CCRT. D-CEUS of the neck lymph nodes was performed at day 0, 8 and 15 after famitinib was administered before starting concurrent chemoradiotherapy. End points included safety, tolerability and anti-tumour activity. RESULTS Twenty patients were enrolled (six each for 12.5, 16.5 and 20 mg and two for 25 mg). Two patients in the 25 mg cohort developed dose-limiting toxicities, including grade 4 thrombocytopenia and grade 3 hypertension. The most common grade 3/4 adverse events were leukopenia, neutropenia and radiation mucositis. D-CEUS tests showed that more than 60% of patients achieved a perfusion parameter response after 2 weeks taking famitinib alone, and the parameter response was associated with disease improvement. In the famitinib monotherapy stage, three patients (15%) showed partial responses. The complete response rate was 65% at the completion of treatment and 95% 3 months after the treatment ended. After a median follow-up of 44 months, the 3-year progression-free survival (PFS) and distant metastasis-free survival were 70% and 75%, respectively. Subjects with a decrease of perfusion parameter response, such as peak intensity decreased at least 30% after 1 week of famitinib treatment, had higher 3-year PFS (90.9% vs. 44.4%, 95% CI 73.7%-100% vs. 11.9%-76.9%, P < 0.001) than those with an increase or a reduction of less than 30%. CONCLUSIONS The recommended famitinib dose for phase II trial is 20 mg with CCRT for patients with local advanced NPC. D-CEUS is a reliable and early measure of efficacy for famitinib therapies. Further investigation is required to confirm the effects of famitinib plus chemoradiotherapy.

Abstract
PURPOSE The purpose of this study was to evaluate the long-term clinical outcome and toxicity of induction chemotherapy (IC) followed by concomitant chemoradiotherapy (CCRT) compared with CCRT alone for the treatment of children and adolescent locoregionally advanced nasopharyngeal carcinoma (LACANPC). MATERIALS AND METHODS A total of 194 locoregionally advanced nasopharyngeal carcinoma patients youngerthan 21 years who received CCRT with or without IC before were included in the study population. Overall survival (OS) rate, progression-free survival (PFS) rate, locoregional recurrence-free survival (LRFS) rate, and distant metastasis-free survival (DMFS) rate were assessed by the Kaplan-Meier method and a log-rank test. Treatment toxicities were clarified and compared between two groups. RESULTS One hundred and thiry of 194 patients received IC+CCRT. Patients who were younger and with more advanced TNM stage were more likely to receive IC+CCRT and intensive modulated radiotherapy. The addition of IC before CCRT failed to improve survival significantly. The matched analysis identified 43 well-balanced patients in both two groups. With a median follow-up of 51.5 months, no differences were found between the IC+CCRT group and the CCRT group in 5-year OS (83.7% vs. 74.6%, p=0.153), PFS (79.2% vs. 73.4%, p=0.355), LRFS (97.7% vs. 88.2%, p=0.083), and DMFS (81.6% vs. 81.6%, p=0.860). N3 was an independent prognostic factor predicting poorer OS, PFS, and DMFS. The addition of IC was associated with increased rates of grade 3 to 4 neutropenia. CONCLUSION This study failed to demonstrate that adding IC before CCRT could provide a significant additional survival benefit for LACANPC patients. Further investigations are warranted.

Abstract
Background: To assess the prognosis of neck residue nasopharyngeal carcinoma (NPC) patients and the efficacy of neck dissection in the treatment of these patients. Methods: We recruited 68 neck residue NPC patients. For each neck residue patient we had three matched NPC patients without neck residue as controls (n = 204). The primary endpoint was progression-free survival (PFS). The Cox proportional hazards model was used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs), and multivariable analysis was used to test the independent statistical significance of NPC patients. Results: Compared to controls, the neck residue patients showed significantly lower 3-year PFS (46.7% vs. 87.6%; P < 0.001). Multivariable analysis showed that neck residue was an independent prognostic factor for PFS. Conclusions: NPC patients who had pathologically proven neck residue are associated with poor prognosis. Management with neck dissection alone seems not to be sufficient for these patients.

Abstract
Background Despite wide usage, peripherally inserted central catheter (PICC)-related venous thromboembolism (VTE) is common in nasopharyngeal carcinoma (NPC) patients. Patients and methods This was a retrospective cohort study of NPC patients with PICC insertions from February 2, 2007 to December 25, 2014 in Sun Yat-Sen University Cancer Centre. Univariable and multivariable logistic regression analyses were used to estimate odds ratios (ORs) with 95% confidence intervals (CIs) for the correlations between risk factors and symptomatic PICC-VTE. Results Of the 1,363 NPC patients, 76 developed symptomatic VTE. In univariable analysis, body mass index (BMI), Eastern Cooperative Oncology Group (ECOG) score, metastasis stage (M stage), and VTE history were associated with symptomatic PICC-VTE. Following multivariable adjustments, BMI (OR 0.900, p=0.007), ECOG score (OR 4.162, p=0.011), M stage (OR 2.717, p=0.019), and VTE history (OR 109.772, p<0.001) were still statistically significant. Conclusion PICC-VTE is a common complication in NPC patients, with an incidence of 5.6% in our analysis. Those with VTE history and lower BMI and worse ECOG performance score metastatic NPC patients are more susceptible to symptomatic PICC-related thrombosis and thus may require prophylactic anticoagulation.

Concurrent chemoradiotherapy with nedaplatin versus cisplatin in stage II-IVB nasopharyngeal carcinoma: an open-label, non-inferiority, randomised phase 3 trial. Lancet Oncol 2018; 19:461-473. [PMID: 29501366 DOI: 10.1016/s1470-2045(18)30104-9] [Citation(s) in RCA: 82] [Impact Index Per Article: 13.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2017] [Revised: 12/15/2017] [Accepted: 12/18/2017] [Indexed: 01/31/2023]
Abstract
BACKGROUND Cisplatin-based concurrent chemoradiotherapy is currently considered to be the standard treatment regimen for patients with advanced nasopharyngeal carcinoma, but has well known side-effects such as gastrointestinal reactions, nephrotoxicity, and ototoxicity. Nedaplatin was developed to decrease the toxic effects induced by cisplatin, and in this trial we assessed whether a nedaplatin-based concurrent chemoradiotherapy regimen was non-inferior to a cisplatin-based regimen in patients with locoregional, stage II-IVB nasopharyngeal carcinoma. METHODS We did an open-label, non-inferiority, phase 3, randomised, controlled trial at two centres in China. Patients aged 18-65 years with non-keratinising stage II-IVB (T1-4N1-3 or T3-4N0) nasopharyngeal carcinoma, a Karnofsky score of at least 70, and adequate haematological, renal, and hepatic function were randomly assigned (1:1) to receive intravenously either nedaplatin 100 mg/m2 or cisplatin 100 mg/m2 on days 1, 22, and 43 for three cycles concurrently with intensity-modulated radiotherapy. Randomisation was done manually using a computer-generated random number code and patients were stratified by treatment centre and clinical stage. Patients and clinicians were not masked to treatment allocation. The primary endpoint was progression-free survival at 2 years; non-inferiority was shown if the upper limit of the 95% CI for the difference in 2-year progression-free survival between the two groups did not exceed 10%. Analyses were by both intention to treat and per protocol, including all patients who received at least one complete cycle of chemotherapy. This trial is registered with ClinicalTrials.gov, number NCT01540136, and is currently in follow-up. FINDINGS Between Jan 16, 2012, and July 16, 2014, we randomly assigned 402 patients to nedaplatin-based (n=201) or cisplatin-based (n=201) concurrent chemoradiotherapy. In the intention-to-treat population, 2-year progression-free survival was 89·9% (95% CI 85·8-94·0) in the cisplatin group and 88·0% (83·5-94·5) in the nedaplatin group, with a difference of 1·9% (95% CI -4·2 to 8·0; pnon-inferiority=0·0048). In the per-protocol analysis (cisplatin group, n=197; nedaplatin group, n=196), 2-year progression-free survival was 89·7% (95% CI 85·4-94·0) in the cisplatin group and 88·7% (84·2-94·5) in the nedaplatin group, with a difference of 1·0% (95% CI -5·2 to 7·0; pnon-inferiority=0·0020). A significantly higher frequency of grade 3 or 4 vomiting (35 [18%] of 198 in the cisplatin group vs 12 [6%] of 200 in the nedaplatin group, p<0·0001), nausea (18 [9%] vs four [2%], p=0·0021), and anorexia (53 [27%] vs 26 [13%], p=0·00070) was observed in the cisplatin group compared with the nedaplatin group. 11 (6%) patients in the nedaplatin group had grade 3 or 4 thrombocytopenia compared with four (2%) in the cisplatin group (p=0·065). Patients in the cisplatin group had a higher frequency of any grade or grade 3 or 4 late auditory or hearing toxicities than did patients in the nedaplatin group (grade 3 or 4: three [2%] in the nedaplatin group vs 11 [6%] in the cisplatin group, p=0·030). No patients died from treatment-related causes. INTERPRETATION Our findings show that nedaplatin-based concurrent chemoradiotherapy represents an alternative doublet treatment strategy to cisplatin-based concurrent chemoradiotherapy for patients with locoregional, advanced nasopharyngeal carcinoma. Further investigations are needed to explore the potential use of this treatment as induction or adjuvant chemotherapy or in combination with other agents.
