Abstract
Background Induction chemotherapy (ICT) augmentation is a common strategy for standard concurrent chemoradiotherapy (CCRT) of locoregionally advanced nasopharyngeal carcinoma (NPC). The survival condition is a crucial issue for patients with locoregionally advanced NPC. The survival of ICT patients with CCRT treatment versus standard CCRT alone should be elucidated via a systemic review and meta-analysis of randomized clinical trials. Methods We compared ICT with CCRT and CCRT alone treatment to determine if ICT with CCRT can be associated with a significant benefit of survival conditions versus CCRT. Different survival indicators were analyzed for the ICT with CCRT. Twelve studies with a total of 3711 patients with locoregionally advanced NPC were enrolled. The focused outcome was the overall survival, progression-free survival, distant metastasis-free survival, and locoregional recurrence-free survival. Results Our results showed that ICT with CCRT is associated with a significant benefit for the overall survival status versus CCRT treatment. Similar significant benefits in the survival condition were seen in progression-free survival, distant metastasis-free survival, and locoregional recurrence-free survival. Conclusions The updated meta-analysis results suggest that the ICT with CCRT might be associated with significant benefits of survival in overall, progression-free, distant metastasis-free, as well as locoregional recurrence-free dimensions versus CCRT treatment. However, the bias of different kinds, doses, and regimens of chemotherapy agents and radiotherapy should not be ignored.

Abstract
PurposeInduction chemotherapy followed by concurrent chemoradiotherapy (IC-CCRT) may be beneficial for nasopharyngeal carcinoma. However, the evidence on medium- and long-term effects of IC-CCRT is limited, and new randomized controlled trials (RCTs) have been published after 2018. Therefore, this systematic review and meta-analysis compared survival rates between patients with nasopharyngeal carcinoma receiving IC-CCRT or concurrent chemoradiotherapy (CCRT).MethodsFour databases were searched for RCTs on this topic. Two authors independently selected studies, assessed evidence, and extracted data on progression-free survival, overall survival, metastasis-free survival, and local recurrence-free survival. Available data were pooled in a random-effects model and mainly presented in hazard ratio (HR). Heterogeneity and small study effects were also evaluated.ResultsEleven RCTs (n = 3345) were deemed eligible. Pooled results revealed that patients receiving IC-CCRT had significantly improved progression-free survival (HR = 0.66, P < 0.05), overall survival (HR = 0.64, P < 0.05), metastasis-free survival (HR = 0.58, P < 0.05), and local recurrence-free survival (HR = 0.69, P < 0.05) at 3 years, but no significant difference in 5-year overall survival was noted between IC-CCRT and CCRT (HR = 0.84, P > 0.05). Most findings had low heterogeneity.ConclusionIC-CCRT may benefit patients with nasopharyngeal carcinoma in the medium term, although no significant difference was observed in 5-year survival compared with CCRT. All outcomes had decreased survival rate from the 3-years to 5-year follow-up. Differences in patient ethnicities and regimens of IC-CCRT may be sources of heterogeneity.

Does three cycles of neoadjuvant chemotherapy prior to concurrent chemoradiotherapy provide benefits for all childhood patients with locoregionally advanced nasopharyngeal carcinoma? J Cancer Res Clin Oncol 2021; 148:2569-2579. [PMID: 34618220 DOI: 10.1007/s00432-021-03817-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 09/24/2021] [Indexed: 12/09/2022]
Abstract
BACKGROUND Adding neoadjuvant chemotherapy (NAC) to concurrent chemoradiotherapy (CCRT) is the main strategy in treatment of children and adolescents with locoregionally advanced nasopharyngeal carcinoma (CA-LANPC). Yet, an optimal number of NAC cycles remains unknown. We aimed to optimize the NAC cycle and potentially contribute to clinical decision making for the individual treatment of CA-LANPC. PATIENTS AND METHODS Utilizing an NPC-specific database through an acknowledged big-data information system at our center, we identified 143 CA-LANPC treated with NAC followed by CCRT between September 2007 through April 2018. Recursive partitioning analysis (RPA) was performed to categorize the patients and predict disease-free survival (DFS). The clinical benefits of NAC cycles (two cycles vs three cycles) were assessed in each risk group. RESULTS Independent factors derived from multivariable analysis to predict DFS were T stage (T1-3 vs T4) and plasma Epstein-Barr virus (EBV) DNA (< 4000 vs ≥ 4000 copies/mL) for risk stratification. Consequently, 87 (61%) participants were classified as low-risk group (T1-3 with low or high EBV DNA, and T4 with low EBV DNA) and the other 56 patients (39%) were classified as a high-risk group (T4 with high EBV DNA) through RPA, and corresponding 5-year DFS rates of 91.9% and 71.2%, respectively (p = 0.001). Among the high-risk group, patients receiving three cycles of NAC had statistically significant improvement in 5-year DFS over those who received two cycles of NAC (86.7% vs 59.1%; p = 0.020), while the survival benefit of three cycles NAC for low-risk groups were not observed (94.7% vs 89.7%; p = 0.652). CONCLUSIONS We found three cycles of NAC with CCRT was a positive prognostic indicator for improved DFS for the high-risk group among CA-LANPC. However, whether low-risk patients could benefit from three cycles NAC needs further study.

Pretreatment Plasma EBV-DNA Load Guides Induction Chemotherapy Followed by Concurrent Chemoradiotherapy in Locoregionally Advanced Nasopharyngeal Cancer: A Meta-Analysis. Front Oncol 2021; 10:610787. [PMID: 33665166 PMCID: PMC7921716 DOI: 10.3389/fonc.2020.610787] [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: 09/29/2020] [Accepted: 12/30/2020] [Indexed: 12/21/2022] Open
Abstract
Background The efficacy of induction chemotherapy (IC) followed by concurrent chemoradiotherapy (CCRT) in locoregionally advanced nasopharyngeal cancer (LA-NPC) is controversial. In this paper, we conduct a meta-analysis based on relevant studies to provide strong evidence for clinical strategies. Materials and Methods We searched the MEDLINE, Embase, Cochrane, PubMed, and Web of Science databases for studies that stratified patients based on a high or low plasma Epstein–Barr virus deoxyribonucleic acid (EBV-DNA) load before treatment and compared the clinical efficacy of IC+CCRT vs. CCRT alone in LA-NPC. We tested for heterogeneity of studies and conducted sensitivity analysis. Subgroup analysis was performed for overall survival (OS), progression-free survival (PFS), distant metastasis-free survival (DMFS), and locoregional relapse-free survival (LRFS). Results Seven studies with a total of 5289 cases were finally included in the meta-analysis. The heterogeneity test revealed the homogeneity of OS (I2 = 0.0%, p=0.794), PFS (I2 = 0.0%, p=0.778), DMFS (I2 = 0.0%, p=0.997), and LRFS (I2 = 0.0%, p=0.697) in patients with EBV-DNA loads of ≥4000 copies/ml in both the IC+CCRT and CCRT groups. The results reveal that IC+CCRT significantly extended the OS (HR 0.70 [95% CI 0.58-0.83], p=0.000), PFS (HR 0.83 [95% CI 0.70-0.99], p=0.033), and DMFS (HR 0.79 [95% CI 0.69-0.9], p=0.000) of patients compared with the CCRT group, but there were no beneficial effects on LRFS (HR 1.07 [95% CI 0.80-1.42], p=0.647). The heterogeneity test found that there was no significant heterogeneity of PFS (I2 = 0.0%, p=0.564), DMFS (I2 = 0.0%, p=0.648), LRFS (I2 = 22.3%, p=0.257), and OS (I2 = 44.6%, p=0.164) in patients with EBV-DNA loads of <4000 copies/ml. The results show that IC+CCRT prolonged DMFS (HR 0.57 [95% CI 0.39-0.85], p=0.006) of patients without significant improvements in OS (HR 0.88 [95% CI 0.55-1.26], p=0.240), PFS (HR 0.98 [95% CI 0.74-1.31], p=0.908), and LRFS (HR 0.98 [95% CI 0.54-1.77], p=0.943). Conclusions Pretreatment plasma EBV-DNA can be considered a promising effective marker for the use of IC in LA-NPC patients. The addition of IC could improve the OS and PFS of patients with EBV-DNA load ≥4000 copies/ml, but we saw no efficacy in patients with EBV-DNA load <4000 copies/ml. Moreover, regardless of the EBV-DNA load, IC could improve DMFS, but there was no effect on LRFS.

Abstract
IMPORTANCE The role of induction chemotherapy (IC) or adjuvant chemotherapy (AC) in the treatment of locoregionally advanced nasopharyngeal carcinoma (NPC) remains controversial. OBJECTIVES To update meta-analyses on the association of survival outcomes with IC and AC regimens in patients with locoregionally advanced NPC and assess whether the current evidence is conclusive by a trial sequential analysis (TSA) approach. DATA SOURCES PubMed, Embase, and Web of Science were searched for articles published from inception until June 1, 2019. STUDY SELECTION Randomized clinical trials that assessed the efficacy of radiotherapy with or without chemotherapy among previously untreated patients and patients with nondistant metastatic NPC. DATA EXTRACTION AND SYNTHESIS Data were extracted by 2 investigators from each trial independently and synthesized by the 2 investigators. All trial results were combined and analyzed by a fixed- or random-effects model. MAIN OUTCOMES AND MEASURES Overall survival (OS), progression-free survival (PFS), distant metastasis-free survival (DMFS), and locoregional recurrence-free survival (LRFS). RESULTS A total of 8036 patients (median age, 46.5 years; 5872 [73.1%] male) from 28 randomized clinical trials were included in the analysis. Pooled analyses revealed that concurrent chemoradiotherapy (CCRT) was significantly associated with improved OS, PFS, DMFS, and LRFS compared with radiotherapy across all subgroups. The TSA confirmed the treatment outcomes of CCRT compared with radiotherapy. The additional IC regimen was associated with an improvement in OS (hazard ratio [HR], 0.84; 95% CI, 0.74-0.95), PFS (HR, 0.73; 95% CI, 0.64-0.84), DMFS (HR, 0.67; 95% CI, 0.59-0.78), and LRFS (HR, 0.74; 95% CI, 0.64-0.85). These findings were consistent in subgroup analyses of multicenter trials with sample sizes greater than 250, years of survival rate of 5 or greater, median follow-up longer than 5 years, or low risk of bias. However, the additional AC regimen was not associated with a survival benefit in OS (HR, 0.98; 95% CI, 0.78-1.23), PFS (HR, 0.86; 95% CI, 0.70-1.07), DMFS (HR, 0.84; 95% CI, 0.64-1.10), or LRFS (HR, 0.80, 95% CI, 0.59-1.09). The TSA provided sound evidence on the additional benefit of IC but not AC. CONCLUSIONS AND RELEVANCE These data suggest a significant association of survival outcomes with CCRT in patients with locoregionally advanced NPC. The addition of IC instead of AC could achieve survival benefits. The potential therapeutic gain of AC should be explored in the future.

Abstract
Objective Plasma Epstein-Barr virus (EBV) DNA concentration at the time of diagnosis (pre-EBV) can be used to stratify risk for nasopharyngeal cancer (NPC) patients. However, pre-EBV cut-off values vary among studies. Methods This was a post hoc analysis of 208 NPC patients from a phase II/III study comparing sequential (SEQ) vs. simultaneous integrated boost (SIB) intensity modulated radiation therapy. The objective was to identify the optimal pre-EBV cut-off value to predict overall survival (OS), progression free survival (PFS) and distant metastatic free survival (DMFS) rates. Results The pre-EBV and post-treatment EBV DNA (post-EBV) were detectable in 59.1% and 3.8% of the patients, respectively. A new pre-EBV cut-off value of 2300 copies/ml was identified by the receiver operating characteristics analysis. This cut-off value showed 82% sensitivity, 59% specificity and 31.7% positive and 93.5% negative predictive values in predicting OS. The 3-year OS, PFS and DMFS were 95.6 vs. 73.8%, 89.8 vs. 55.3% and 93 vs. 70.1% for pre-EBV < vs. ≥2300 copies/ml, respectively. Older age group (≥45 years), high pre-EBV and detectable post-EBV concentration were independent predictors for OS, PFS and DMFS in a multivariate analysis. When the stage grouping and pre-EBV value were combined, a subgroup of patients with stage II-III and pre-EBV values <2300 copies/ml. had the best survival outcomes, while the worst survival subgroup was the patients with stage III-IVb with pre-EBV values ≥2300 copies/ml. Conclusions Pre-EBV cut-off of 2300 copies/ml is an optimal value predicting OS, PFS and DMFS.
