[PMID: 38366691 DOI: 10.1002/hed.27680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Revised: 01/28/2024] [Accepted: 01/30/2024] [Indexed: 02/18/2024] Open
Abstract
BACKGROUND The effect of radiotherapy waiting time after last induction chemotherapy (IC-RT) on prognosis of patients with locally advanced nasopharyngeal carcinoma (LANPC) needs further discussion. METHODS Three hundred and six patients with LANPC diagnosed pathologically by induction chemotherapy (IC) and radiotherapy (RT) from 2013 to 2018 were selected for this study. RESULTS The IC-RT was a risk factor for the post-treatment progression of LANPC (OR = 1.017 95%CI: 1.003-1.031), For patients with LANPC, the IC-RT > 40 days significantly reduced 5-year PFS (70% vs. 55%; p = 0.0012), 5-year OS (84% vs. 73%; p = 0.028), 5-year DMFS (80% vs. 66%; p = 0.003), 5-year LRFS (77% vs. 67%; p = 0.012). Indicating that patients with stage IVa who IC-RT > 40 days were found to be a significant predictor of aggravated PFS (HR = 2.69; 95%CI: 1.57-4.6), OS (HR = 2.55; 95%CI: 1.29-5.03), DMFS (HR = 3.07; 95%CI: 1.64-5.76) and LRFS (HR = 2.26; 95%CI: 1.21-4.21). CONCLUSION The prognosis of patients will be adversely affected if the IC-RT exceeds 40 days, especially for stage IVa patients.

Abstract
PURPOSE To estimate diffusion tensor imaging (DTI) parameters for early diagnosis during the stage of radiation-induced brain injury (RBI) in nasopharyngeal carcinoma (NPC) patients.PubMed, Embase, Web of Science and Cochrane Library were searched up to March 2019. Eligible studies comparing early brain injuries with controls of temporal lobe in NPC patients before and after radiotherapy which collected the DTI parameters such as apparent diffusion coefficient (ADC), fractional anisotropy (FA), axial diffusibility (λa), radial diffusibility (λr), mean diffusion (MD) were included. CONCLUSION Seven studies (N = 21) were selected from the studies in the databases. Overall, FA, λa, λr values were significant difference between early RBI and healthy control (HC) in NPC patients after radiotherapy (MD= -0.03, 95% CI= -0.05∼-0.01; p = .008 in FA, MD= -0.07, 95% CI= -0.11∼-0.02; p = .002 in λa and MD = 0.02, 95% CI = 0.00 ∼ 0.04; p = .04 in λr). The meta regression analysis about dose dependence with FA value was: -0.057 ∼ 0.0003 in 95% CI, I2=74.70%, P = 0.052 (adjust p = .029). The overall heterogeneity is p < .001, I2=91% in FA, P = 0.08, I2=61% in λa and p = .04, I2=69% in λr. DTI parameters such as the reduced FA value, the decreased λa value, and the increased λr value were significant in the early period of RBI in NPC patients after radiotherapy, which becoming a more sensitive method in diagnosing the early stage of RBI.

Radiotherapy interruption due to holidays adversely affects the survival of patients with nasopharyngeal carcinoma: a joint analysis based on large-scale retrospective data and clinical trials. Radiat Oncol 2022; 17:36. [PMID: 35183221 PMCID: PMC8858542 DOI: 10.1186/s13014-022-02006-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 02/07/2022] [Indexed: 12/26/2022] Open
Abstract
Background The impact of radiotherapy interruption due to the Spring Festival holidays in China on the survival of patients with nasopharyngeal carcinoma (NPC) is unclear. Methods Nontrial patients with locoregionally advanced NPC receiving radiotherapy plus induction chemotherapy (IC) and/or concurrent chemotherapy (CC) were included (N = 5035) and divided into two groups based on the Spring Festival-induced radiotherapy interruption. Kaplan–Meier curves for overall survival (OS) and failure-free survival (FFS) were compared between rival groups. Impact of the timing of radiotherapy interruption (during or outside the Spring Festival) on survival was investigated in a propensity score-matched dataset. We adopted ordination correspondence analysis to determine the cut-off of radiotherapy prolongation for prognostic prediction, and accordingly performed subgroup analysis based on delayed days and chemotherapy details. Individual patient data of three phase III NPC trials (NCT00677118, NCT01245959, NCT01872962) were used for validation (N = 1465). Results Radiotherapy interruption was most frequently observed between December to January of the following year. Significantly lower OS and FFS were associated with the Spring Festival-induced interruption of radiotherapy (P = 0.009 and 0.033, respectively), but not that interruption of IC. In two matched comparison groups, the timing of radiotherapy interruption during the Spring Festival was more likely to lead to a decrease in FFS than outside the Spring Festival (P = 0.046), which was not observed in the validation using clinical trial data or in the subgroup analysis based on the 5-day delayed time. The absence of CC and the accumulated dose of cisplatin < 200 mg were related to the negative influences of the Spring Festival-induced radiotherapy interruption on FFS (P = 0.002) and OS (P = 0.010), respectively. Conclusions The poor survival of patients with NPC is associated with the Spring Festival-induced interruption of radiotherapy. We recommend that these patients receive adequate doses of cisplatin concurrently with radiotherapy.

Abstract
PURPOSE To explore the prognostic impact of waiting time for radiotherapy (RT) after induction chemotherapy (IC) for nasopharyngeal carcinoma (NPC). METHODS AND MATERIALS A total of 648 NPC patients receiving IC between 2009 and 2011 were included. Propensity score matching (PSM) was performed to balance the variables. Survival outcomes were compared in subgroups based on time to RT (TTR) after IC. RESULTS The optimal cutoff point for TTR was 28 days. A total of 330 patients were selected by 1:2 PSM. Stratified and dichotomized TTRs were both strongly correlated with prognosis. Patients with TTR > 28 days had significantly worse 5-year LRFS, DMFS, DFS and OS than those with TTR ≤ 28 days (P < 0.05). In multivariate analysis, TTR > 28 days was an independent predictor of worse LRFS [HR=2.08; 95% CI, 1.18-3.66; P = 0.011), DMFS (HR=1.65; 95% CI, 1.04-2.62; P = 0.033), DFS (HR=1.86; 95% CI, 1.35-2.62; P < 0.001) and OS (HR=1.90; 95% CI, 1.26-2.85; P < 0.001). High-risk patients with T4 or N2-3 disease were highly susceptible to RT delay with impaired DFS and OS. In high-risk patients with TTR > 28 days, concurrent chemotherapy yielded better DMFS (70.9% vs. 52.0%, P = 0.041), DFS (52.5% vs. 34.3%, P = 0.039) and OS (70.3% vs. 53.2%, P = 0.048). CONCLUSIONS Prolonged waiting is detrimental to survival in NPC, and it is strongly recommended to start RT within 28 days after IC. T4/N2-3 NPC has a higher risk of treatment failure with delayed RT. With potential protection against RT delay, concurrent chemotherapy should be performed in high-risk patients as salvage therapy.

A novel prognostic model predicts overall survival in patients with nasopharyngeal carcinoma based on clinical features and blood biomarkers. Cancer Med 2021; 10:3511-3523.

Abstract
This study aims to develop and validate a novel prognostic model to estimate overall survival (OS) in nasopharyngeal carcinoma (NPC) patients based on clinical features and blood biomarkers. We assessed the model's incremental value to the TNM staging system, clinical treatment, and Epstein‐Barr virus (EBV) DNA copy number for individual OS estimation. We retrospectively analyzed 519 consecutive patients with NPC. A prognostic model was generated using the Lasso regression model in the training cohort. Then we compared the predictive accuracy of the novel prognostic model with TNM staging, clinical treatment, and EBV DNA copy number using concordance index (C‐index), time‐dependent ROC (tdROC), and decision curve analysis (DCA). Subsequently, we built a nomogram for OS incorporating the prognostic model, TNM staging, and clinical treatment. Finally, we stratified patients into high‐risk and low‐risk groups according to the model risk score, and we analyzed the survival time of these two groups using Kaplan–Meier survival plots. All results were validated in the independent validation cohort. Using the Lasso regression, we established a prognostic model consisting of 13 variables with respect to patient prognosis. The C‐index, tdROC, and DCA showed that the prognostic model had good predictive accuracy and discriminatory power in the training cohort than did TNM staging, clinical treatment, and EBV DNA copy number. Nomogram consisting of the prognostic model, TNM staging, clinical treatment, and EBV DNA copy number showed some superior net benefit. Based on the model risk score, we split the patients into two subgroups: low‐risk (risk score ≤ −1.423) and high‐risk (risk score > −1.423). There were significant differences in OS between the two subgroups of patients. Similar results were observed in the validation cohort. The proposed novel prognostic model based on clinical features and serological markers may represent a promising tool for estimating OS in NPC patients.

Abstract
Nasopharyngeal carcinoma (NPC) arises from the epithelium of the nasopharyngeal mucosa. Elderly people above the age of 65 years are more susceptible to NPC. Nasopharyngectomy is the renowned treatment procedure to NPC; however, it is too risky due to its complicated surgical procedure. Other treatment methods also reported with serious side effects such brain injury; hence, the alternative anticancer drug without any side effects was needed. Fucoxanthin is a carotenoid derived from marine algae with the numerous pharmacological functions. This study aims to examine the inhibitory potential in NPC cell proliferation via apoptosis and autophagy. The cytotoxicity of fucoxanthin on C666-1 cells was observed by the MTT assay. The expression of autophagy-linked proteins was assessed with immunoblotting analysis. The expression of autophagy protein LC3 was estimated using immunocytochemical analysis in C666-1 and GFP-LC3 transfected cells. Furthermore, the fucoxanthin-treated C666-1 cells were analyzed with TUNEL assay. The apoptotic level in the fucoxanthin-treated C666-1 cells was evaluated using acridine orange staining. Fucoxanthin significantly increased the expression of autophagy-linked proteins which is clearly depicted in the immunoblotting analysis and immunocytochemical analysis of GFP-tagged LC3 protein. The results of TUNEL assay of fucoxanthin-treated C666-1 in the presence autophagy inhibitors demonstrated the induction of autophagy by fucoxanthin. Acridine orange staining results of C666-1 confirmed fucoxanthin decreases the expression of autophagy-linked proteins during stressed condition thereby causes apoptosis. Our overall results authentically conclude that fucoxanthin induces autophagy and apoptosis in NPC cell line, and it can be ideal agent to treat nasopharyngeal cancer in future with further investigations.
