Abstract
PURPOSE Whether cervical lymph node necrosis (CNN) is an independent adverse prognostic factor in nasopharyngeal carcinoma (NPC) has not been determined. In this study, the CNN ratio was graded quantitatively to explore the prognostic value in NPC. PARTICIPANTS AND METHODS We retrospectively reviewed a total of 648 pathologically confirmed as NPC. We outlined metastatic lymph nodes and necrotic area of lymph nodes slice by slice on the magneticresonanceimages (MRI) cross section, and calculated the corresponding CNN ratio. RESULTS The median CNN ratio (17.37 %) was taken as the cut-off point, 256 (39.51 %) patients were divided into CNN1 group (<17.37 %, n = 128) and CNN2 group (≥17.37 %, n = 128), 392 (60.49 %) patients without lymph nodes necrosis were CNN0. Among the CNN0, CNN1 and CNN2 groups, five-year overall survival (OS) was 82.4 %, 76.6 % and 71.1 %, locoregional recurrence-free survival (LRRFS) was 91.3 %, 91.1 % and 90.5 %, distant metastasis-free survival (DMFS) was 83.7 %, 78.5 % and 68.7 %, progression-free survival (PFS) was 78.3 %, 71.7 % and 61.6 % respectively. By multivariate analysis, CNN was an independent prognostic factor for OS (P = 0.003), DMFS (P = 0.019) and PFS (P = 0.007). More than 3 cycles of chemotherapy significantly increased OS (P = 0.024) and DMFS (P = 0.015) in the CNN1 group. CONCLUSIONS This study indicated that CNN is one of the factors with the negative prognosis of NPC. The CNN ratio might be used as one of the reference factors in the formulation of individualized treatment plan.

Efficacy of adjuvant chemotherapy/maintenance chemotherapy after induction chemotherapy and concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma: Experiences of two centers. Cancer Med 2022; 12:6811-6824. [PMID: 36420689 PMCID: PMC10067090 DOI: 10.1002/cam4.5470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 10/16/2022] [Accepted: 11/13/2022] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND AND OBJECTIVE In general, there are not many studies exploring the clinical value of adjuvant chemotherapy or maintenance chemotherapy (AC/MC) after induction chemotherapy and concurrent chemoradiotherapy (IC+CCRT+AC/MC). The purpose of this study was to establish a clinical nomogram for the use of AC/MC in patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC). MATERIAL AND METHODS Two centers (Guangzhou Medical University Cancer Center [N = 1226] and Zhongshan People's Hospital [N = 150]) recruited 1376 patients with LA-NPC. All the patients underwent IC+CCRT; 560 patients received AC with cisplatin/nedaplatin plus docetaxel/paclitaxel (TP) or cisplatin/nedaplatin plus fluorouracil (PF), and 81 patients received MC with S-1. Multivariate Cox regression was used to confirm optimal predictors of progression-free survival (PFS), and a nomogram was established to identify patients into low-risk and high-risk cohorts. Additionally, bootstrap internal validation was performed to further verify our nomogram. RESULTS After propensity score matching (PSM), the survival curves were not statistically different between IC+CCRT+AC/MC and IC+CCRT (all p > 0.05). Then, a nomogram was developed based on variables that were screened by univariate and multivariate Cox regression, including N stage, cumulative platinum dose during CCRT, body mass index (BMI), IC cycles, IC regimen and cervical lymph node (CLN) necrosis and infiltration of adjacent tissues. The results of the nomogram showed that the high-risk cohort had greatly worse 5-year DMFS, LRFS, PFS and OS compared to low-risk cohort (all p < 0.05), and subgroup analysis found that the 5-year DMFS, PFS and OS of patients treated with IC+CCRT+AC/MC were better than those treated with IC+CCRT in high-risk cohort (all p < 0.05). Notably, the incidence of adverse effects for IC+CCRT+AC cohort was higher than that for IC+CCRT+MC cohort, especially leukocytopenia and neutropenia. IC+CCRT and IC+CCRT+MC were associated with similar incidences of adverse effects. CONCLUSIONS The addition of AC or MC to IC+CCRT could improve the DMFS of patients with high-risk NPC and prolong their survival. Additionally, our findings suggest a potential role of AC/MC following IC plus CCRT in the treatment of high-risk LA-NPC.

Prognostic value of quantitative cervical nodal necrosis burden on MRI in nasopharyngeal carcinoma and its role as a stratification marker for induction chemotherapy. Eur Radiol 2022; 32:7710-7721. [PMID: 35437613 DOI: 10.1007/s00330-022-08785-5] [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: 08/19/2021] [Revised: 03/22/2022] [Accepted: 03/26/2022] [Indexed: 01/03/2023]
Abstract
OBJECTIVES This study aimed to assess the prognostic value of quantitative cervical nodal necrosis (CNN) burden in N staging risk stratification in patients with nasopharyngeal carcinoma. METHODS Univariate and multivariate Cox regression models evaluated the association between lymph node variables based on MRI images and survival. Revisions for the N classification system were proposed and compared to the 8th edition AJCC staging system using Harrell's concordance index (C-index). The survival outcomes of induction chemotherapy plus concurrent chemoradiotherapy (CCRT) and CCRT alone in patients with multiple CNNs were compared. RESULTS In 1319 patients enrolled, CNN was not an independent prognostic factor for the main survival outcomes, but multiple CNNs (three or more necrotic nodes) were independent prognostic factors for distant metastasis-free survival (DMFS) (adjusted hazard ratio [HR], 2.05; p = 0.020) and progression-free survival (PFS) (HR, 1.78; p = 0.004), surpassing other nodal variables. On upgrading patients with multiple CNNs to revised N3 disease, the proposed N staging widened the differences in DMFS and PFS between N2 and N3 disease. The overall survival of patients with multiple CNNs who received CCRT plus induction chemotherapy was improved compared to that of those who received CCRT alone (76.1% vs. 55.7%; adjusted p = 0.030). CONCLUSIONS Upgrading patients with multiple CNNs to stage N3 may improve prognostication of the current AJCC staging system. Multiple CNNs might be a potential marker for stratifying patients who would benefit from induction chemotherapy. KEY POINTS • Quantitatively assessed the prognostic value of CNN burden in patients with NPC. • Upgrading patients with multiple CNNs to stage N3 may improve prognostication. • Multiple CNNs may be used as a stratification marker for induction chemotherapy.

Abstract
Purpose We aimed to select optimal candidates benefiting from the addition of induction chemotherapy (IC) to concurrent chemoradiotherapy (CCRT) in advanced N-stage nasopharyngeal carcinoma (NPC). Patients and Methods A total of 624 NPC patients with N2-3 stage received CCRT with or without IC were retrospectively reviewed. We constructed a nomogram for predicting overall survival (OS) based on the result of the multivariate analysis in the training cohort (n = 468) and then tested it on the validation cohort (n = 156). Harrell’s concordance indices (C-index) and time-independent receiver operating characteristic (tdROC) analysis were applied to evaluate the discriminatory ability of the nomogram and compare it with TNM staging. IC plus CCRT was compared with CCRT in the whole cohort and two risk groups based on the nomogram with balanced baseline characteristics. In addition, acute toxicities were compared between different treatment groups. Results The nomogram showed good prognostic accuracy with a C-index of 0.716 (95% CI 0.669–0.763) in the validation cohort. The 5-year OS of low and high-risk groups stratified by the nomogram were significantly different. IC+CCRT was significantly associated with superior OS as compared with CCRT (75.4 vs 52.6%, p = 0.009) in the high-risk group. However, no significant difference between IC plus CCRT and CCRT was observed (p = 0.843) in the low-risk group. IC plus CCRT was associated with more grade 1–4 acute toxicities. Conclusion Our study can help clinicians select NPC patients with advanced N stage who benefit from IC.

Prognostic value of cervical nodal necrosis on staging imaging of nasopharyngeal carcinoma in era of intensity-modulated radiotherapy: a systematic review and meta-analysis. Cancer Imaging 2022; 22:24. [PMID: 35596198 PMCID: PMC9123677 DOI: 10.1186/s40644-022-00462-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Accepted: 05/13/2022] [Indexed: 12/02/2022] Open
Abstract
Purposes To systematically review and perform meta-analysis to evaluate the prognostic value of cervical nodal necrosis (CNN) on the staging computed tomography/magnetic resonance imaging (MRI) of nasopharyngeal carcinoma (NPC) in era of intensity-modulated radiotherapy. Methods Literature search through PubMed, EMBASE, and Cochrane Library was conducted. The hazard ratios (HRs) with 95% confidence intervals (CIs) of CNN for distant metastasis-free survival (DMFS), disease free survival (DFS) and overall survival (OS) were extracted from the eligible studies and meta-analysis was performed to evaluate the pooled HRs with 95%CI. Results Nine studies, which investigated the prognostic values of 6 CNN patterns on MRI were included. Six/9 studies were eligible for meta-analysis, which investigated the CNN presence/absence in any nodal group among 4359 patients. The pooled unadjusted HRs showed that the CNN presence predicted poor DMFS (HR =1.89, 95%CI =1.72-2.08), DFS (HR =1.57, 95%CI =1.08-2.26), and OS (HR =1.87, 95%CI =1.69-2.06). The pooled adjusted HRs also showed the consistent results for DMFS (HR =1.34, 95%CI =1.17-1.54), DFS (HR =1.30, 95%CI =1.08-1.56), and OS (HR =1.61, 95%CI =1.27-2.04). Results shown in the other studies analysing different CNN patterns indicated the high grade of CNN predicted poor outcome, but meta-analysis was unable to perform because of the heterogeneity of the analysed CNN patterns. Conclusion The CNN observed on the staging MRI is a negative factor for NPC outcome, suggesting that the inclusion of CNN is important in the future survival analysis. However, whether and how should CNN be included in the staging system warrant further evaluation.
