Concurrent chemoradiotherapy versus radiotherapy alone in older patients with stage II nasopharyngeal carcinoma after intensity-modulated radiotherapy: A propensity score-matched cohort study. Radiother Oncol 2024; 191:110081. [PMID: 38185256 DOI: 10.1016/j.radonc.2024.110081] [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: 05/31/2023] [Revised: 12/28/2023] [Accepted: 01/01/2024] [Indexed: 01/09/2024]
Abstract
BACKGROUND AND PURPOSE Whether concurrent chemoradiotherapy (CCRT) benefits the older (age ≥ 60 years) patients with stage II nasopharyngeal carcinoma (NPC) has not been determined. This study aimed to compare the outcomes and toxicities of CCRT with Intensity-Modulated Radiotherapy (IMRT) alone in older patients with stage II NPC. MATERIALS AND METHODS Between January 2010 and December 2017, 220 older (age ≥ 60 years) patients with stage II NPC were analyzed. A pair of 53 patients were matched between the CCRT group and RT group by using propensity score matching (PSM) in terms of age, sex, pathological type, T and N stage, ACE-27 scores, CRP, LDH and Hb. Cancer-specific survival (CSS), progression-free survival (PFS), locoregional relapse-free survival (LRRFS) and distant metastasis-free survival (DMFS) were analysed by the Kaplan-Meier method and log-rank test. Multivariate analysis was performed to assess the prognostic risk factors by using a Cox's proportional hazards regression model. Treatment toxicities were clarified and compared between the two groups by using the χ2 test. RESULTS The median follow-up time of the whole cohort was 82.0 months (range, 11-151 months). PSM analysis indicated that compared with the RT group, significantly higher 5-year CSS (98.1 % vs. 83.0 %, P = 0.02), PFS (98.1 % vs. 79.2 %, P = 0.01) and DMFS (100.0 % vs. 92.4 %, P = 0.04) were observed in the CCRT group. Multivariate analysis showed that CCRT was an independent prognostic factor predicting CSS (HR, 0.34; 95 % CI, 0.15-0.79; P = 0.01), PFS (HR, 0.48; 95 % CI, 0.25-0.93; P = 0.03), and LRRFS (HR, 0.36; 95 % CI, 0.14-0.90; P = 0.03), and a higher ACE-27 score predicted a worse CSS. Patients in the CCRT group experienced higher frequencies of the acute toxicities than patients in the RT group. Late complications were comparable between the two groups. CONCLUSION CCRT significantly improved the survival benefits for the older patients with stage II NPC compared with IMRT alone without adding late complications, whereas increased some of the treatment-associated acute toxicities.

Abstract
Chemotherapy remains controversial for stage II nasopharyngeal carcinoma because of its considerable prognostic heterogeneity. We aimed to develop an MRI-based deep learning model for predicting distant metastasis and assessing chemotherapy efficacy in stage II nasopharyngeal carcinoma. This multicenter retrospective study enrolled 1072 patients from three Chinese centers for training (Center 1, n = 575) and external validation (Centers 2 and 3, n = 497). The deep learning model significantly predicted the risk of distant metastases for stage II nasopharyngeal carcinoma and was validated in the external validation cohort. In addition, the deep learning model outperformed the clinical and radiomics models in terms of predictive performance. Furthermore, the deep learning model facilitates the identification of high-risk patients who could benefit from chemotherapy, providing useful additional information for individualized treatment decisions.

Concurrent chemoradiotherapy versus radiotherapy alone for stage II nasopharyngeal carcinoma in the era of intensity-modulated radiotherapy. Eur Arch Otorhinolaryngol 2023; 280:3097-3106. [PMID: 37079074 DOI: 10.1007/s00405-023-07943-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 03/25/2023] [Indexed: 04/21/2023]
Abstract
BACKGROUND Concurrent chemoradiotherapy has long been a standardized therapy for localized advanced nasopharyngeal cancer. It is widely used in clinical applications. In contrast, NCCN guidelines highlight that the efficacy of concurrent chemoradiotherapy for stage II nasopharyngeal cancer in the new era of intensity-modulated radiotherapy has not been defined. Thus, we systematically reviewed the significance of concurrent chemoradiotherapy for stage II nasopharyngeal cancer. METHODS We searched the relevant literature in PubMed, EMBASE, and Cochrane, extracting relevant data from the searched literature. The main items extracted were hazard ratios (HRs), risk ratios (RRs) and 95% confidence intervals (CIs). When the HR could not be extracted from the literature, we used Engauge Digitizer software for extraction. Data analysis was accomplished using the Review Manager 5.4 tool. RESULTS Our study included seven articles involving 1633 cases of stage II nasopharyngeal cancer. The survival outcomes were overall survival (OS) (HR = 1.03, 95% CI (0.71-1.49), P = 0.87), progression-free survival (PFS) (HR = 0.91, 95% CI (0.59-1.39), P = 0.66), distant metastasis-free survival (DMFS) (HR = 1.05, 95% CI (0.57-1.93), P = 0.87), local recurrence-free survival (LRFS) (HR = 0.87, 95% CI (0.41-1.84), P = 0.71, P > 0.05), and locoregional failure-free survival (LFFS) (HR = 1.18, 95% CI (0.52-2.70), P = 0.69). CONCLUSIONS In the era of intensity-modulated radiotherapy, concurrent chemoradiotherapy and radiotherapy alone have the same survival benefits, and concurrent chemoradiotherapy increases acute hematological toxicity. Subgroup analysis showed that for people with N1 nasopharyngeal cancer at risk of distant metastases, concurrent chemoradiotherapy and radiotherapy alone also had equal survival benefits.

The role of radiologic extranodal extension in predicting prognosis and chemotherapy benefit for T1-2 N1 nasopharyngeal carcinoma: A multicenter retrospective study. Radiother Oncol 2023; 178:109436. [PMID: 36464180 DOI: 10.1016/j.radonc.2022.11.025] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 09/30/2022] [Accepted: 11/25/2022] [Indexed: 12/05/2022]
Abstract
BACKGROUND AND PURPOSE This multicenter retrospective study aimed to investigated the prognostic value of unequivocal radiologic extranodal extension (rENE) and the efficacy of chemotherapy for stage T1-2 N1 nasopharyngeal carcinoma (NPC) in the IMRT era. MATERIALS AND METHODS We included 1,082 patients treated in 2005-2017 from three centers. rENE was recorded as G1 (coalescent nodal mass comprising ≥ 2 inseparable nodes) or G2 (invading beyond perinodal fat to frankly infiltrate adjacent structures). Multivariable analysis (MVA) evaluated the prognostic value of rENE. The value of chemotherapy was assessed in rENE-positive (rENE + ) and rENE-negative (rENE - ) subset separately. RESULTS Centers 1, 2, and 3 had 139/515 (27.0 %), 100/365 (27.4 %), and 43/202 (21.3 %) cN + patients with rENE, respectively. Compared to rENE-, rENE + patients had a worse distant metastasis-free survival (DMFS) and overall survival (OS) (all p < 0.001). MVA confirmed the prognostic of both G1-rENE and G2-rENE for distant metastasis [G1: hazard ratio (HR): 2.933, G2: HR: 6.942, all p < 0.001] and death (G1: HR: 1.587, p = 0.040; G2: HR: 6.162, p < 0.001). There was no significant difference for DMFS and OS between chemo-radiotherapy and radiotherapy alone in rENE + and rENE - groups (all p > 0.1). However, rENE + patients with a cumulative cisplatin/nedaplatin dose (CCND) of > 160 mg/m2 had an improved DMFS (p = 0.033) but no OS (p = 0.197). CONCLUSION Unequivocal rENE is prognostic in patients with T1-2 N1 NPC. Addition of chemotherapy to radiotherapy did not affect DMFS and OS in rENE - patients. Chemotherapy with a CCND of > 160 mg/m2 improved DMFS in rENE + patients.

A Systematic Review and Meta-Analysis of Studies Comparing Concurrent Chemoradiotherapy With Radiotherapy Alone in the Treatment of Stage II Nasopharyngeal Carcinoma. Front Oncol 2022; 12:843675. [PMID: 35903695 PMCID: PMC9317745 DOI: 10.3389/fonc.2022.843675] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2021] [Accepted: 05/31/2022] [Indexed: 12/09/2022] Open
Abstract
Purpose The role of concurrent chemoradiotherapy (CCRT) in stage II nasopharyngeal carcinoma (NPC) is still controversial. Our objective is to evaluate the value of concurrent chemotherapy in stage II NPC receiving radiotherapy (RT). Methods We searched the PubMed, Embase, and Scopus databases for studies comparing CCRT versus RT alone in stage II NPC with survival outcomes and toxicities, including locoregional recurrence-free survival (LRFS), metastasis-free survival (DMFS), progression-free survival (PFS), overall survival (OS), and grade 3–4 acute toxicities. The hazard ratios (HRs) of survival outcomes and risk ratios (RRs) of toxicities were extracted for meta-analysis. Subgroup analysis for stage N1 patients was performed to further explore whether these populations can earn benefits from concurrent chemotherapy. Results Nine eligible studies with a total of 4,092 patients were included. CCRT was associated with a better OS (HR = 0.61, 95% CI 0.44–0.82), LRFS (HR = 0.62, 95% CI 0.50–0.78), and PFS (HR = 0.65, 95% CI 0.54–0.79), but with similar DMFS (HR = 0.81, 95% CI = 0.46–1.45) compared with two-dimensional RT (2DRT) alone. However, CCRT showed no survival benefit in terms of OS (HR = 0.84, 95% CI 0.62–1.15), LRFS (HR = 0.85, 95% CI 0.54–1.34), DMFS (HR = 0.96, 95% CI 0.60–1.54), and PFS (HR = 0.96, 95% CI 0.66–1.37) compared with intensity-modulated RT (IMRT) alone. Subgroup analyses indicated that CCRT had similar OS (HR = 1.04, 95% CI 0.37–2.96), LRFS (HR = 0.70, 95% CI 0.34–1.45), DMFS (HR = 1.03, 95% CI 0.53–2.00), and PFS (HR = 1.04, 95% CI 0.58–1.88) in the stage N1 populations. Meanwhile, compared to RT alone, CCRT significantly increased the incidence of grade 3–4 leukopenia (RR = 4.00, 95% CI 2.29–6.97), mucositis (RR = 1.43, 95% CI 1.16–1.77), and gastrointestinal reactions (RR = 8.76, 95% CI 2.63–29.12). No significant differences of grade 3–4 toxicity in thrombocytopenia (RR = 3.45, 95% CI 0.85–13.94) was found between the two groups. Conclusion For unselected patients with stage II NPC, CCRT was superior to 2DRT alone with better LRFS, PFS, and OS, while adding concurrent chemotherapy to IMRT did not significantly improve survival but exacerbated acute toxicities.

Abstract
To assess survival between subgroups (T1N1, T2N0, and T2N1) of patients with stage II nasopharyngeal carcinoma (NPC). This retrospective cohort study evaluated pathologically confirmed stage II NPC patients from The Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2016. The included patients were divided into three subgroups: T1N1, T2N0, and T2N1. Overall survival (OS) and cancer-specific survival (CSS) were assessed using the Kaplan-Meier method among the three subgroups. This study investigated 836 patients: 383 (45.8%) patients were in the T1N1 subgroup, 175 (20.9%) patients were in the T2N0 subgroup, and 278 (33.3%) patients were in the T2N1 subgroup. The 5-year OS (75.7%, 68.6%, and 75.7%) and CSS (85.3%, 83.4%, and 84.5%) were similar among the T1N1, T2N0, and T2N1 subgroups. Univariate and multivariate regression analyses revealed that the subgroup (T1N1, T2N0, and T2N1) of stage II NPC was not an independent prognostic factor for OS or CSS. Survival was comparable among subgroups (T1N1, T2N0, and T2N1) of stage II NPC patients. However, patients with T1N1, T2N0, and T2N1 stage disease who receive different treatments might have different prognoses.

[PMID: 34953045 PMCID: PMC8855903 DOI: 10.1002/cam4.4520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 12/07/2021] [Accepted: 12/08/2021] [Indexed: 11/14/2022] Open
Abstract
Purpose We aimed to develop and prospectively validate a risk score model to guide individualized concurrent chemoradiotherapy (CCRT) for patients with stage II nasopharyngeal carcinoma (NPC) in intensity‐modulated radiotherapy (IMRT) era. Materials and Methods In total, 1220 patients who received CCRT or IMRT alone were enrolled in this study, including a training cohort (n = 719), a validation cohort (n = 307), and a prospective test cohort (n = 194). Patients were stratified into different risk groups by a risk score model based on independent prognostic factors, which were developed in the training cohort. Survival rates were compared by the log‐rank test. The validation and prospective test cohorts were used for validation. Results Total tumor volume, Epstein–Barr virus DNA, and lactate dehydrogenase were independent risk factors for failure‐free survival (FFS, all p < 0.05). A risk score model based on these three risk factors was developed to classify patients into low‐risk group (no risk factor, n = 337) and high‐risk group (one or more factors, n = 382) in the training cohort. In the high‐risk group, CCRT had better survival rates than IMRT alone (5‐year FFS: 82.6% vs. 74.0%, p = 0.028). However, there was no survival difference between CCRT and IMRT alone either in the whole training cohort (p = 0.15) or in the low‐risk group (p = 0.15). The results were verified in the validation and prospective test cohorts. Conclusion A risk score model was developed and prospectively validated to precisely select high‐risk stage II NPC patients who can benefit from CCRT, and thus guided individualized treatment in IMRT era.

Abstract
Nasopharyngeal carcinoma (NPC) is a severe malignancy arising from the nasopharyngeal epithelium and is southern China's third most common cancer. With the advancement of treatment methods, early-stage NPC patients usually have a better prognosis and more prolonged survival period than those with other malignant tumors. Most treatment failures are due to distant metastasis or a locally advanced stage of NPC in the initial diagnosis. In addition, approximately 10% of patients develop local recurrence, and 10%-20% of patients experience distant metastasis after treatment. These patients have a poor prognosis, with a median survival of only approximately 10-15 months. In the rapid development of treatment options, the efficacy and safety of some treatments have been validated and approved for first-line treatment, while those of other treatments remain unclear. The present study aims to provide a comprehensive overview of recent advances in NPC treatment and explain the various therapeutic possibilities in treating locally advanced, recurrent, and metastatic NPC patients.

Prognostic significance of metabolic tumour volume and maximum standard uptake value of fluor-18-fluorodeoxyglucose positron emission tomography with computed tomography in nasopharyngeal carcinoma. Contemp Oncol (Pozn) 2021; 25:153-159. [PMID: 34729034 PMCID: PMC8547178 DOI: 10.5114/wo.2021.109620] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 08/19/2021] [Indexed: 11/17/2022] Open
Abstract
Aim of the study To evaluate the prognostic role of markers of fluor-18-fluorodeoxyglucose positron emission tomography with computed tomography (18F-FDG-PET-CT), such as maximum standard uptake value (SUVmax) and metabolic tumour volume (MTV) measured at primary and nodal disease, and their clinical significance in terms of predicting treatment outcomes and survival. Material and methods Between January 2017 and January 2020, 20 case records of nasopharyngeal carcinoma patients who underwent 18F-FDG-PET-CT as part of staging workup before radiotherapy and as a part of response evaluation after radiotherapy were retrospectively reviewed. Results At a median follow-up of 34.7 months, the 2-year progression-free survival (PFS) was 70% and 2-year overall survival (OS) was 79%. Patients with a lower nodal SUVmax (SUVmax-N) had a better 2-year PFS (91% vs. 46%; p = 0.035) and 2-year OS (95% vs. 58%; p = 0.015). A high SUVmax-N of > 10.58 was a negative predictor of OS (95% confidence interval [CI]: 0.93-1; p = 0.003) as well as PFS (95% CI: 0.64-1; p = 0.017). Also, a high MTV > 25.8 cm3 was a negative predictor of PFS (95% CI: 0.58-0.98; p = 0.048). MTV was an independent predictor of PFS and OS on univariate analysis, whereas it was not significant in the Cox regression multivariate analysis. Conclusions High values of MTV and SUVmax-N can be considered as independent prognostic factors of OS and PFS in nasopharyngeal cancer patients treated with concurrent chemoradiation, highlighting the need for more intensified treatment.

Abstract
Objective: This study aims to compare the treatment outcomes of concurrent chemoradiotherapy (CCRT) versus radiotherapy (RT) alone in stage II nasopharyngeal carcinoma (NPC) patients. Methods: We retrospectively collected 601 stage II NPC patients treated in two hospitals between June 2003 to June 2016. All patients were divided into the CCRT group (n = 255) and the RT group (n = 346). Overall survival (OS), locoregional failure-free survival (LRFFS), progression-free survival (PFS), and distant metastasis-free survival (DMFS) were assessed using the Kaplan-Meier method. The log-rank test was used to compare the differences between the groups. The Cox-regression hazards model was performed to determine potential prognostic factors. Results: The median follow-up was 99 months. No significant difference was found in locoregional recurrence, distant metastasis, disease progression, and death between the two groups (all p > 0.05). In univariate analysis, the 5-years OS, PFS, LRFFS, and DMFS had no significant differences between the CCRT and RT groups (all p > 0.05). Two-dimensional radiotherapy (2DRT) sub-analysis showed that CCRT remarkably increased DMFS, PFS, and OS rates (all p < 0.05) but not LRFFS (p = 0.258) compared with RT alone. While intensity-modulated radiotherapy (IMRT) sub-analysis showed that the prognosis of the two groups had no significant differences (all p > 0.05). In multivariate analyses, age was significantly and inversely related to OS, PFS, LRFFS, and DMFS. IMRT was an independent favorable factor for improving LRFFS, PFS, and OS. Concurrent chemotherapy was an independent protective factor for DMFS. Conclusion: In the context of 2DRT, it is definite that concurrent chemotherapy provides survival benefits for patients with stage II NPC. While in the IMRT era, the impact of chemotherapy on survival in patients with stage II NPC is weakened. Prospective randomized controlled studies are required to confirm these results.

External Validation of a Nomogram to Predict Survival and Benefit of Concurrent Chemoradiation for Stage II Nasopharyngeal Carcinoma. Cancers (Basel) 2021; 13:cancers13174286. [PMID: 34503096 PMCID: PMC8428339 DOI: 10.3390/cancers13174286] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 08/20/2021] [Indexed: 12/29/2022] Open
Abstract
Simple Summary The optimal treatment strategy (concurrent chemoradiation (CCRT) vs. radiotherapy alone) for stage II nasopharyngeal carcinoma (NPC) in the intensity-modulated radiotherapy (IMRT) era is controversial across guidelines. A nomogram by Sun et al. was published to predict the overall survival (OS) benefit of CCRT based on a patient’s clinical parameters. Using the cohort from the Hong Kong NPC1301 study, we evaluated the external validity of the nomogram and the associations between the proposed clinical factors and OS among stage II NPC patients. Use of CCRT was an insignificant predictor for OS. The nomogram lacked the predictive accuracy and should be interpreted with caution. Abstract A nomogram was recently published by Sun et al. to predict overall survival (OS) and the additional benefit of concurrent chemoradiation (CCRT) vs. radiotherapy (RT) alone, in stage II NPC treated with conventional RT. We aimed to assess the predictors of OS and to externally validate the nomogram in the IMRT era. We analyzed stage II NPC patients treated with definitive RT alone or CCRT between 2001 and 2011 under the territory-wide Hong Kong NPC Study Group 1301 study. Clinical parameters were studied using the Cox proportional hazards model to estimate OS. The nomogram by Sun et al. was applied with 1000 times bootstrap resampling to calculate the concordance index, and we compared the nomogram predicted and observed 5-year OS. There were 482 patients included. The 5-year OS was 89.0%. In the multivariable analysis, an age > 45 years was the only significant predictor of OS (HR, 1.98; 95%CI, 1.15–3.44). Other clinical parameters were insignificant, including the use of CCRT (HR, 0.99; 95%CI, 0.62–1.58). The nomogram yielded a concordance index of 0.55 (95% CI, 0.49–0.62) which lacked clinically meaningful discriminative power. The nomogram proposed by Sun et al. should be interpreted with caution when applied to stage II NPC patients in the IMRT era. The benefit of CCRT remained controversial.

Eur Arch Otorhinolaryngol 2021; 278:3333-3344. [PMID: 33517538 DOI: 10.1007/s00405-020-06593-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Accepted: 12/24/2020] [Indexed: 12/15/2022]
Abstract
PURPOSE The current study set out to compare the efficacies and toxicities (grad 3 and 4) between concurrent chemoradiotherapy (CCRT), induction chemotherapy plus radiotherapy (IC + RT), IC + CCRT, RT and CCRT + adjuvant chemotherapy (CCRT + AC) in regard to advanced nasopharyngeal carcinoma (NPC) treatment using a network meta-analysis. METHODS Literature retrieval was conducted using PubMed, Cochrane Library and other English databases. Eligible randomized controlled trails (RCTs) of 5 different regimens were included. The network meta-analysis combined direct and indirect comparisons to measure pooled odd ratios (OR) and the surface under the cumulative ranking curves (SUCRA). RESULTS A total of eight eligible RCTs were enrolled into this network meta-analysis after initial exclusion. With respect to hematologic toxicity, CCRT + AC exhibited higher toxicity in patients with advanced NPC in terms of anemia and leukopenia/neutropenia compared to RT. As for anemia, the toxicity of IC + CCRT was higher than those with advanced NPC. In addition, CCRT exhibited higher toxicity than RT in relation to leukopenia/neutropenia. Non-hematologic toxicity in regard to nausea/vomiting suggested that CCRT, IC + CCRT and CCRT + AC presented with higher levels of toxicity in patients with advanced NPC, in contrast to RT. Lastly, RT was found to be less toxic but with higher five-year overall survival (OS) rate in patients with advanced NPC, while CCRT, IC + CCRT and CCRT + AC were more toxic in patients with advanced NPC. CONCLUSION Among the five therapeutic regimens, the survival rate of IC + RT was similar to that of CCRT, and the toxicity SUCRA value of IC + RT was lower than that of CCRT. Together, our findings indicate that IC + RT may be a potentially acceptable treatment alternative to CCRT for advanced NPC, and is worthy of further investigation.

Abstract
IMPORTANCE Since the advent of modern radiotherapy techniques and incorporation of systemic chemotherapy for nasopharyngeal cancer, locoregional control has been excellent. However, the rate of treatment-related complications, many of which are irreversible, remains high. New approaches are being explored to determine whether the toxic effects of treatment can be relieved while maintaining disease control. This review presents the current state of deescalation strategies for nasopharyngeal cancer. OBSERVATIONS A review of the literature shows that deescalation approaches can be generally categorized into deescalating systemic therapy vs deescalating radiotherapy. This review discusses studies that have explored sparing chemotherapy in selected patients with stage II cancer as well as altering the chemotherapy scheduling, dosing, and agent from the current standard of care, cisplatin. Deescalating radiotherapy has involved decreasing the dose and the treatment volume. In many cases, these approaches are being guided by measuring Epstein-Barr virus DNA levels, which is a robust biomarker for screening, treatment monitoring, and surveillance. Ongoing work with various imaging modalities, such as fluorodeoxyglucose positron emission tomography and dynamic contrast-enhanced or diffusion-weighted magnetic resonance imaging sequences, have shown promise as another biomarker to safely guide practitioners toward deescalation. CONCLUSIONS AND RELEVANCE Various strategies to deescalate treatment in nasopharyngeal cancer have been explored, and outcomes have remained excellent in most approaches. Patient selection remains key, and long-term outcomes and late complications are still to be determined. Continued investigation with prospective, multi-institutional studies are needed to better elucidate how treatment for nasopharyngeal carcinoma can best be individualized and deescalated.

Abstract
PURPOSE To investigate the follow-up strategy of stage II NPC based on event dynamics. METHODS Stage II NPC patients were retrospectively assessed from January 2007 to December 2014 at Guangxi Medical University Cancer Hospital. Event dynamics for patterns of recurrence and metastasis were calculated based on the hazard rates. RESULTS A total of 251 patients were included. After treatment, 10 (4.0%) patients developed recurrence and 6 (2.4%) patients developed metastasis. The hazard rate curve of recurrence showed a bimodal recurrence pattern. The maximum hazard rates were 0.048 and 0.072 at the intervals of 36-42 and 90-96 months, respectively. The maximum hazard rate was 0.036 at the interval of 48-54 months in the hazard rate curve of metastasis. CONCLUSIONS Follow-up strategies of stage II NPC should be performed based on currently recommended guidelines. In the future, it should be modified to meet the needs of individual patients.

Abstract
Background This study directs to evaluate the efficacy and safety of intensity-modulated radiotherapy (IMRT) alone versus IMRT plus chemotherapy in intermediate-risk NPC (stage II and T3N0M0). Methods A total of 124 patients with stage II and T3N0M0 NPC were pair-matched (1:1 ratio) to form two groups: an IMRT-alone group and an IMRT/chemotherapy group. Survival outcomes (overall survival [OS], disease–free survival [DFS], locoregional relapse–free survival [LRRFS], distant metastasis–free survival [DMFS]) and treatment-related grade 3–4 acute toxicity events were compared between the groups. Results Survival outcomes for patients with stage II and T3N0M0 NPC were quiet comparable between patients treated with IMRT alone versus patients treated with IMRT/chemotherapy: 5-year OS was 91.9% vs. 90.3%, respectively (P = 0.727); DFS was 87.1% vs. 88.7%, respectively (P = 0.821); LRFFS was 96.8% vs. 95.2%, respectively (P = 0.646), and DMFS was 91.9% vs. 91.5%, respectively (P = 0.955). Grade 3 acute toxicities were significantly higher with IMRT/chemotherapy than with IMRT alone: mucositis, 15% vs. 5% (P = 0.004); leukopenia/neutropenia, 8% vs. 1% (P < 0.015); and nausea/vomiting, 22% vs. 3% (P < 0.001). Conclusion For intermediate-risk (stage II and T3N0M0) NPC patients, the addition of chemotherapy to IMRT does not appear to provide any survival benefit. Moreover, grade 3 acute toxicities are also more common in patients receiving IMRT plus chemotherapy.

Abstract
Nasopharyngeal carcinoma is an endemic disease with a high prevalence in Southeast Asia, Mediterranean countries, and Northern Africa. With substantial advances in screening and diagnosis, increasingly more early-stage (stage I~II) patients are being diagnosed. The undebated treatment modality for stage I patients is radiotherapy alone. However, controversies exist for patients with stage II disease, mostly revolving around the management of chemotherapy. However, the use of intensity-modulated radiotherapy for the treatment of nasopharyngeal carcinoma has increased recently, which has drastically improved survival outcomes. Thus, many oncologists have considered omitting chemotherapy for stage II patients in the intensity-modulated radiotherapy era. Unfortunately, prospective studies comparing concurrent radio-chemotherapy with intensity-modulated radiotherapy alone are limited. Notably, stage II nasopharyngeal carcinoma consists of three subgroups, among which stage T2N1M0 disease is unique and potentially warrants additional treatment including chemotherapy. Additionally, molecular biology techniques are advancing at an incredible speed. Instead of adopting a one-size-fits-all recommendation, exploring potential predictive biomarkers to select patients who are likely to derive benefit from chemotherapy is a better choice. In this review, we summarize the data from studies and reviews regarding chemotherapy for stage II nasopharyngeal carcinoma in the intensity-modulated radiotherapy era and discuss chemotherapy utility. Eventually, we conclude that IMRT alone may be sufficient for stage II nasopharyngeal carcinoma, but this needs to be verified by prospective studies in the near future, the evidence collected thus far suggests that concurrent chemo-radiotherapy without induction or adjuvant chemotherapy is yet to be necessary for patients with stage II disease.

Abstract
Background: Type 2 diabetes mellitus (T2DM) is a chronic, hyperglycemia-associated, metabolic disorder. Heart disease is a major complication of T2DM. The present study aimed to explore the effects of miR-216a-3p on cardiomyocyte proliferation, apoptosis, and inflammation in T2DM through the Toll-like receptor (TLR) pathway involving interferon-α2 (IFN-α2) mediation. Methods: T2DM was induced in rats by a high-fat diet, in combination with an intraperitoneal injection of low-dose streptozotocin. ELISAs were conducted to measure inflammatory-related factors in serum. Next, isolated cardiomyocytes were used in loss- and gain-of-function experiments, followed by MTT and flow cytometry assays, conducted to evaluate cell proliferation, cell cycle, and apoptosis. Results: Our results revealed an increase in the inflammatory response in T2DM rat models, accompanied by significantly increased expression of miR-216a-3p and TLR pathway-related genes. However, a decrease in the expression of IFN-α2 was observed. Moreover, the presence of an miR-216a-3p inhibitor and si-IFN-α2 increased the expression of TLR pathway-related genes and cell apoptosis, whereas cell proliferation was significantly decreased in the cardiomyocytes. Conclusion: We found that in T2DM, miR-216a-3p inhibited the proliferation and enhanced the apoptosis of cardiomyocytes and generated an inflammatory response through activation of the TLR pathway and targeting of IFN-α2.

Abstract
PURPOSE Chemotherapy use remains controversial for stage II nasopharyngeal carcinoma (NPC). This retrospective study was conducted to identify whether chemoradiotherapy was associated with better survival compared to radiotherapy. MATERIALS AND METHODS The Surveillance, Epidemiology, and End Results (SEER) database was queried for stage II NPC patients between 2004 and 2015. Patients were divided into radiotherapy and chemoradiotherapy groups. Overall survival (OS) and cancer-specific survival (CSS) were examined using the Kaplan-Meier method, Cox proportional hazards models, and propensity score matching analyses. RESULTS This study examined 908 patients, including 102 receiving radiotherapy and 806 receiving chemoradiotherapy. Chemoradiotherapy was associated with 5-year OS (78.01% vs. 75.12%; p = 0.22) and CSS (78.92% vs. 78.26%; p = 0.40) rates comparable to those of radiotherapy. Propensity score matching analyses demonstrated similar OS (HR: 0.63, 95% CI: 0.36--1.10; p = 0.10) and CSS (HR: 0.77, 95% CI: 0.41-1.48; p = 0.44) rates with radiotherapy. Age >60 years and non-Asian patients were associated with worse survival. CONCLUSION This study revealed that chemoradiotherapy showed similar survivals to stage II NPC patients compared with radiotherapy. Due to the limitations of SEER database, further studies should be performed to verify the results.

Establishment and validation of a nomogram for predicting the benefit of concurrent chemotherapy in stage II nasopharyngeal carcinoma: A study based on a phase III randomized clinical trial with 10-year follow-up. Oral Oncol 2019; 100:104490. [PMID: 31790913 DOI: 10.1016/j.oraloncology.2019.104490] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2019] [Revised: 11/14/2019] [Accepted: 11/23/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND AND PURPOSE Our previous phase III randomized trial demonstrated that the addition of concurrent chemotherapy to radiotherapy (RT) could improve survival in stage II nasopharyngeal carcinoma (NPC). Based on the study, we sought to develop a nomogram for predicting the 5-year and 10-year survival of patients with stage II NPC and estimating the benefit of concurrent chemoradiotherapy (CCRT) for individual patients. MATERIALS AND METHODS Data of 199 enrolled patients from the original trial was analyzed to build a nomogram. Overall survival (OS) was the primary endpoint. The discrimination and calibration capacities were evaluated using Harrell Concordance Index (C-index) and calibration curves, respectively. Internal validation of the nomogram was performed by a separate cohort of 306 patients from the same cancer center. RESULT In training cohort, patients in CCRT group achieved higher 5-year and 10-year OS compared with patients in RT group. Three independent prognostic factors, which were age, N stage and treatment method from multivariable analysis were extracted to enter the nomogram. T stage was also included due to its importance in clinical decisions. The Harrell C-index of the nomogram in training and validation cohort was 0.748 and 0.653 respectively. The calibration curves showed an acceptable agreement between prediction and observed probability. CONCLUSION We developed and validated a nomogram to predict the 5-year and 10-year OS in stage II NPC patients. The nomogram could serve as a pragmatic tool in clinical decisions to estimate the individual risk of stage II patients and identify those who could benefit from chemotherapy.

[PMID: 31743830 PMCID: PMC6872832 DOI: 10.1016/j.tranon.2019.08.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 08/06/2019] [Accepted: 08/07/2019] [Indexed: 12/09/2022] Open
Abstract
PURPOSE In contrast to other studies, our previous study showed that adding induction chemotherapy (IC) to concurrent chemoradiotherapy (CCRT) significantly worsened the prognosis of patients with stage II nasopharyngeal carcinoma (NPC). However, the population used was small; therefore, there is an urgent need to confirm the result in a larger population because IC is still widely used in certain sections of china for stage II NPC. METHODS AND MATERIALS We retrospectively analyzed an additional 272 patients. Therefore, in total, we report the results for 445 patients with stage II NPC treated with IC + CCRT or CCRT between June 2003 to June 2016 at the Zhejiang Cancer Hospital and Sun Yat-Sen University Cancer Center. RESULTS This study included 445 patients treated with IC + CCRT (n = 195) or CCRT (n = 250). By last analysis, 22 (11.3%) patients in the IC + CCRT group developed local-regional recurrence and 23 (11.8%) patients developed distant metastases. Twenty-four (9.6%) patients in the CCRT group developed local-regional recurrence and 12 (4.8%) patients developed distant metastases. Univariate analyses showed that adding IC to CCRT significantly decreased the 5-year disease-free survival (DFS) (80.6% vs. 88.5%, P = .043); however, there was no statistically significant difference in 5-year overall survival (OS) (90.5% vs. 95.0%, P = .375). CONCLUSION Using a larger population, the present study showed that adding IC to CCRT had a negative effect on patients with stage II NPC, which warrants further investigation.

Ten-Year Outcomes Of Intensity-Modulated Radiotherapy (IMRT) Combine With Chemotherapy Versus IMRT Alone For Stage II Nasopharyngeal Carcinoma In The Real-World Study (RWD). Cancer Manag Res 2019; 11:8893-8903. [PMID: 31632149 PMCID: PMC6791404 DOI: 10.2147/cmar.s218842] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2019] [Accepted: 09/14/2019] [Indexed: 11/30/2022] Open
Abstract
Objectives The aim was to define the role of chemotherapy in stage II nasopharyngeal carcinoma (NPC) and to identify the toxicity of chemotherapy for these patients in the era of intensity-modulated radiotherapy (IMRT). Methods Between January 2002 and December 2013, 169 patients with stage II NPC were analyzed. Of these patients, 149 patients treated with chemotherapy were divided into three groups as follows: neoadjuvant chemotherapy followed by IMRT (NCT) group, concurrent chemotherapy with IMRT (CCRT) group, and neoadjuvant chemotherapy followed by CCRT (NC+CCRT) group. In addition, 20 patients received IMRT alone. We retrospectively assessed the 10-year survival and acute adverse effects in the patients using SPSS software. Results The median follow-up time was 93 months (2–160 months). The 10-year OS of the NCT, CCRT, NC+CCRT groups vs the IMRT alone group was 69.8%, 63.4%, 69.7% vs 72.4%, respectively (P=0.664, 0.940, and 0.998, respectively). Both univariable and multivariable analyses showed that the addition of chemotherapy to IMRT did not significantly improve the 10-year survival outcomes. The hematotoxicity and mucous reaction of patients with chemotherapy were more serious than those with IMRT alone (P=0.007 and 0.049). Distant metastasis for stage II NPC patients mostly occurred within 3 years, which is very different from patients with advanced NPC. Conclusion Patients with stage II NPC who are treated with IMRT may obtain satisfactory long-term survival outcomes. The additional chemotherapy cannot significantly increase survival; however, it may remarkably increase treatment-associated acute toxic reactions.

Abstract
Purpose To assess the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) in stage II nasopharyngeal carcinoma (NPC). Methods Stage II (2010 UICC/AJCC staging system) NPC patients treated between January 2007 and December 2014 were retrospectively analyzed. The NLR was calculated from peripheral blood cell counts before treatment. The optimal cut-off value of NLR was determined by receiver operating characteristic curve analysis. Survival rates were compared according to the NLR value. Multivariable Cox regression analyses were performed to assess the association between the NLR and overall survival (OS), locoregional-free survival (LRFS), and distant metastasis-free survival (DMFS). Results Two hundred and fifty-one stage II NPC patients were included in this study. The NLR was correlated with T stage (r=0.158, p=0.012). An NLR ≥2.92 was associated with poor 5-year OS (84.3% vs 97.4%, p=0.001) and LRFS (91.4% vs 98.4%, p=0.003). An NLR ≥2.82 was associated with poor 5-year DMFS (92.6% vs 98.2%, p=0.033). The multivariate Cox regression analysis showed that an NLR ≥2.92 was an independent prognostic biomarker in stage II NPC. Conclusion The NLR is an independent prognostic factor in stage II NPC.

Abstract
BACKGROUND Tumor-nodal-metastasis (TNM) is the most important survival predictor in nasopharyngeal carcinoma (NPC). Distant metastasis (DM) is the predominant failure pattern of NPC in the intensity-modulated radiotherapy (IMRT) era. The DM risk appears to be different for T-N subsets within the same clinical stage. Appropriately depicting DM risk has emerged as an important issue in tailoring individualized treatment and underpins the reason for this study. METHODS A total of 1616 non-metastatic (M0) NPC patients treated with IMRT were included. All were re-staged according to the 8th edition AJCC/UICC TNM (TNM-8). DM-free survival (DMFS) was calculated and compared among T-N subsets within each stage and DM risk groups were derived by Recursive-partitioning analysis (RPA) based on ordinal T and N categories. RESULTS Significant heterogeneity in DM risk was evident among T-N subsets within cTNM-8 stages II-IV. The RPA algorithm classified patients into four DM risk groups: RPA-I (T1N0-1 and T2-3N0), RPA-II (T2-3N1), RPA-III (T4N0-1 and T1-3N2) and RPA-IV (T4N2 and T1-4N3), with 5-year DMFS of 93.4% (95% CI: 91.3-96.1), 84.3% (80.8-87.8), 78.9% (75.4-82.4) and 63.6% (56.3-70.9), respectively (p < 0.001). Compared to cTNM-8 stage grouping, RPA grouping had a lower Akaike information criterion (AIC) and higher Harrell's concordance index (c-index) for DMFS. CONCLUSIONS Significant heterogeneity in DM risk exists among T-N subsets within cTNM-8 stages. The RPA groups demonstrated improved intra-group hazard consistency compared to cTNM-8 stage groups. While further validation is warranted, these RPA prognostic groupings provide a strong anatomic foundation to augment DM prediction for optimal targeting in future clinical trials.

Abstract
The standard of care treatment for locally advanced nasopharyngeal carcinoma (NPC) includes both chemotherapy and definitive radiation. However, there are limited data on the optimal management of stage II NPC. We performed a retrospective analysis of the National Cancer Database to analyze the treatment patterns and role of chemotherapy in patients with stage II NPC. We identified 611 patients diagnosed with T1-2, N0-1, M0 NPC, from 2004 to 2013. Five-year survival was calculated using Kaplan Meier (KM) analysis. Multivariable analysis and propensity matched analysis were performed to analyze the impact of chemotherapy on overall survival. Of the 611 patients, 527 underwent concurrent chemoradiation (CCRT) and 84 received radiation only. Unadjusted KM analysis showed improved 5-year survival in the CCRT group compared to radiation only (80.5% vs 65.7%; P = 0.0021). Multivariable analysis also showed improved survival with the addition of chemotherapy (Hazard ratio [HR] 0.59; 95 CI 0.39-0.89; P = 0.0124). Propensity matched analysis confirmed a significant clinical benefit from the addition of chemotherapy to radiation. Age ≥ 65 years (HR 2.41; 95% CI 1.71-3.4; P = <0.0001), Charlson-Deyo comorbidity index >1 (HR 2.82; 95% CI 1.49-5.31; P = 0.0014) and positive lymph node status (HR 1.6; 95% CI 1.04-2.46; P = 0.0340) were associated with worse survival. In this retrospective analysis, patients with stage II NPC had improved survival with CCRT compared to definitive radiation only. Elderly patients with comorbidities had worse outcomes.

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.

Abstract
Identification of predictive factors of chemotherapy use and assessment of the roles of these factors in prognosis will aid therapeutic decision-making in stage II nasopharyngeal carcinoma (NPC).Using logistic regression, we retrospectively assessed factors predicting chemotherapy use in 251 stage II (2010 UICC/AJCC staging system) NPC patients. Five-year overall survival (OS), locoregional-free survival (LRFS), and distant metastasis-free survival (DMFS) were analyzed based on the predictive factors.Logistic regression found that N1 stage was an independent factor predicting chemotherapy use in stage II NPC patients. However, 5-year OS (96.5% vs 94.9%, P = .564), LRFS (98.2% vs 96.9%, P = .652), and DMFS (95.9% vs 97.6%, P = .560) did not differ between N0 and N1 stage patients. Moreover, addition of chemotherapy use did not improve treatment outcomes in N1 stage compared with radiotherapy alone.N1 stage predicted chemotherapy use in stage II NPC patients. But, the addition of chemotherapy did not provide a survival benefit.

Abstract
PURPOSE Little is known about combination of the circulating Epstein-Barr viral (EBV) DNA and tumor volume in prognosis of stage II nasopharyngeal carcinoma (NPC) patients in the intensity modulated radiotherapy (IMRT) era. We conducted this cohort study to evaluate the prognostic values of combining these two factors. MATERIALS AND METHODS By Kaplan-Meier, we compare the differences of survival curves between 385 patients with different EBV DNA or tumor volume levels, or with the combination of two biomarkers mentioned above. RESULTS Gross tumor volume of cervical lymph nodes (GTVnd, p < 0.001) and total tumor volume (GTVtotal, p < 0.001) were both closely related to pretreatment EBV DNA, while gross tumor volume of nasopharynx (GTVnx, p=0.047) was weakly related to EBV DNA. EBV DNA was significantly correlated with progress-free survival (PFS, p=0.005), locoregional-free survival (LRFS, p=0.039), and distant metastasis-free survival (DMFS, p=0.017), while GTVtotal, regardless of GTVnx and GTVnd, had a significant correlation with PFS and LRFS. The p-values of GTVtotal for PFS and LRFS were 0.008 and 0.001, respectively. According to GTVtotal and pretreatment EBV DNA level, patients were divided into a low-risk group (EBV DNA 0 copy/mL, GTVtotal < 30 cm3; EBV DNA 0 copy/mL, GTVtotal ≥ 30 cm3; or EBV DNA > 0 copy/mL, GTVtotal < 30 cm3) and a high-risk group (EBV DNA > 0 copy/mL, GTVtotal ≥ 30 cm3). When patients in the low-risk group were compared with those in the high-risk group, 3-year PFS (p=0.003), LRFS (p=0.010), and DMFS (p=0.031) rates were statistically significant. CONCLUSION Pretreatment plasma EBV DNA and tumor volume were both closely correlated with prognosis of stage II NPC patients in the IMRT era. Combination of EBV DNA and tumor volume can refine prognosis and indicate for clinical therapy.

Addition of chemotherapy to intensity-modulated radiotherapy does not improve survival in stage II nasopharyngeal carcinoma patients. J Cancer 2018; 9:2030-2037. [PMID: 29896288 PMCID: PMC5995949 DOI: 10.7150/jca.25042] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2018] [Accepted: 02/28/2018] [Indexed: 01/16/2023] Open
Abstract
In this study, we examined whether combining neoadjuvant chemotherapy (NAC) and/or concurrent chemotherapy (CC) with intensity-modulated radiotherapy (IMRT) improved survival in patients with stage II nasopharyngeal carcinoma (NPC). Two hundred forty-two stage II NPC patients were enrolled between May 2008 and April 2014 and received radical IMRT with simultaneous integrated boost technique using 6 MV photons; some patient groups also received chemotherapy every 3 weeks for 2-3 cycles. The median follow-up duration was 69 months for all patients. At the last follow-up, 18 patients had experienced treatment failure; locoregional relapse among the IMRT alone, NAC+IMRT, NAC+CCRT, and CCRT occurred in 3, 3, 4 and 5, respectively; distant metastases in 0, 0, 2 and 1, respectively, and there was a statistically significant difference among four groups (P=0.019). The 5-year locoregional relapse-free survival (LRRFS), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) rates for all patients were 94.7%, 98.7%, 92.9%, and 93.4%, respectively. Five-year LRRFS, DMFS, PFS, and OS were similar among the IMRT alone, NAC+IMRT, NAC+CCRT, and CCRT treatment groups. Univariate and multivariate analyses revealed that a combined regimen was not an independent prognostic factor for any survival outcome. However, patients who received IMRT plus chemotherapy experienced more acute adverse events than those who received IMRT alone. Thus, the addition of NAC and/or CC to IMRT did not improve survival outcomes, but was associated with higher incidences of acute treatment-associated toxicities than IMRT alone in patients with stage II NPC.

Biomed Pharmacother 2018; 102:1003-1014. [PMID: 29710517 DOI: 10.1016/j.biopha.2018.03.114] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2018] [Revised: 03/19/2018] [Accepted: 03/19/2018] [Indexed: 12/12/2022] Open
Abstract
Epstein-Barr virus (EBV) can establish a life-long latent infection in the host and is associated with various human malignancies, including nasopharyngeal carcinoma (NPC), the most common cancer originated from nasopharynx. EBV nuclear antigen 1 (EBNA1) is the only viral protein absolutely demanded for segregation, replication, transcription and maintenance of EBV viral genome in host cells. Baicalein, a bioactive flavonoid compound purified from the root of Scutellariae baicaleinsis, displays anti-inflammatory, immunosuppressive, and anti-tumor properties. In this study, the therapeutic effects and functional mechanism of baicalein on EBV-positive human NPC were determined. Cell Counting Kit-8 assays and cell formation colony were performed to investigate that baicalein can suppress proliferation of EBV-infected human NPC cells. Flow cytometric and hoechst 33258 staining results indicated that baicalein induced cell cycle arrest and apoptosis. Western blotting results demonstrated that baicalein down-regulates EBNA1 expression but not reduces the stability and half-life of EBNA1 in EBV-infected NPC cells. Additionally, the mRNA level of EBNA1 was examined by real time-PCR, the activity of EBNA1 Q promoter (Qp) was determined by dual luciferase reporter assay. Considering that transcription factor specificity protein 1 (Sp1) can maintain EBNA1 Qp active. Further analyses also elucidated that baicalein inhibits the expression of Sp1 while knock-down Sp1 by specific shRNAs decreases the expression and transcription levels of EBNA1. Therefore, the results suggested that baicalein may decrease EBNA1 expression level in EBV-positive NPC cells via inhibiting the activity of EBNA1 Q-promoter while over-expression of EBNA1 attenuate the inhibitory effect of baicalein. Finally, it was found that baicalein may strongly reduce growth of tumor in the mouse xenograft model of EBV-positive NPC. These results indicated that baicalein inhibits growth of EBV-positive NPC by repressing the activity of EBNA1 Q-promoter. Baicalein may be used as a therapeutic agent to treat EBV-positive NPC.

Abstract
The aim of this meta-analysis was to evaluate the efficacy and toxicity of adding chemotherapy to radiotherapy (RT) in the treatment of stage-II nasopharyngeal carcinoma (NPC). We searched Pubmed, Cochrane Library, Embase, China National Knowledge Internet, China Biology Medicine, VIP, and Wanfang database for studies of the RT with or without chemotherapy in patients with stage-II NPC that were published in any language. Analyses were carried out using RevMan 5.3 software. The relative risk was used to evaluate the data, the I2 test was used to compare heterogeneity, sensitivity analysis was used to evaluate the stability and reliability of the results. There were 16 studies with 3038 patients that were included in this analysis. Risk ratios (RR) of 1.04 (95% CI: 1.01-1.06), 1.05 (95% CI: 1.00-1.10), 1.05 (95% CI: 1.02-1.07), and 1.00 (95% CI: 0.97-1.03) were observed for overall survival (OS), progression-free survival (PFS), locoregional failure-free survival (LRFS), and distant metastasis-free survival (DMFS). Subgroup analysis showed that compared with conventional RT alone, chemoradiation (CRT) could significantly improve OS (RR = 1.09, 95% CI: 1.03-1.15), PFS (RR = 1.20, 95% CI: 1.08-1.35), and LRFS (RR = 1.09, 95% CI: 1.04-1.14), but did not significantly improve the rate of DMFS (RR = 1.03, 95% CI: 0.94-1.12). However, compared with intensity modulated radiation therapy alone, CRT did not significantly improve the rate of OS (RR = 1.01, 95% CI: 0.99-1.03), PFS (RR = 0.99, 95% CI: 0.95-1.03), LRFS (RR = 1.02, 95% CI: 0.99-1.05), and DMFS (RR = 0.99, 95% CI: 0.96-1.01). Compared with conventional RT alone, CRT could significantly improve patients' prognoses in terms of OS, PFS, and LRFS for stage-II NPC, but not DMFS, and CRT can provide greater benefits from concurrent chemotherapy than neoadjuvant chemotherapy. With intensity modulated radiation therapy, the stage-II NPC patients did not benefit from the addition of chemotherapy.

Abstract
Objectives To compare clinical outcomes of concurrent chemoradiotherapy (CCRT) with those of radiotherapy alone for stage II nasopharyngeal carcinoma in the intensity-modulated radiotherapy (IMRT) era. Materials and methods We comprehensively searched PubMed, Embase, and the Cochrane Library to identify eligible studies. Overall survival (OS), progression-free survival (PFS), distant metastasis-free survival (DMFS), locoregional recurrence-free survival (LRRFS) with hazard ratios (HRs), and toxicities with odd ratios (ORs) were analyzed. Results A total of seven studies met the criteria, with 1302 patients who were treated with IMRT alone or IMRT plus concurrent chemotherapy. No significant survival benefit was shown by CCRT regardless of OS (HR = 1.17, 95% CI 0.73–1.89, P = 0.508), PFS (HR = 0.76, 95% CI 0.38–1.50, P = 0.430), DMFS (HR = 0.89, 95% CI 0.33–2.41, P = 0.816), or LRRFS (HR = 1.03, 95% CI 0.95–1.12, P = 0.498). Additionally, CCRT notably increased the risk of acute grade 3–4 leukopenia (OR = 4.432, 95% CI 2.195–8.952, P < 0.001), compared to IMRT alone. Conclusion Adding concurrent chemotherapy to IMRT led to no survival benefit and increased acute toxicity reactions for stage II nasopharyngeal carcinoma.

Radiat Oncol J 2017; 35:306-316. [PMID: 29207865 PMCID: PMC5769881 DOI: 10.3857/roj.2017.00115] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2017] [Revised: 06/12/2017] [Accepted: 06/30/2017] [Indexed: 12/29/2022] Open
Abstract
Purpose To investigate the predictive role of maximum standardized uptake value (SUVmax) of 2-[18F]fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in nasopharyngeal cancer patients treated with intensity-modulated radiotherapy (IMRT). Materials and Methods Between October 2006 and April 2016, 53 patients were treated with IMRT in two institutions and their PET/CT at the time of diagnosis was reviewed. The SUVmax of their nasopharyngeal lesions and metastatic lymph nodes (LN) was recorded. IMRT was delivered using helical tomotherapy. All patients except for one were treated with concurrent chemoradiation therapy (CCRT). Correlations between SUVmax and patients’ survival and recurrence were analyzed. Results At a median follow-up time of 31.5 months (range, 3.4 to 98.7 months), the 3-year overall survival (OS) and disease-free survival (DFS) rates were 83.2% and 77.5%, respectively. In univariate analysis, patients with a higher nodal pre-treatment SUVmax (≥ 13.4) demonstrated significantly lower 3-year OS (93.1% vs. 55.5%; p = 0.003), DFS (92.7% vs. 38.5%; p < 0.001), locoregional recurrence-free survival (100% vs. 50.5%; p < 0.001), and distant metastasis-free survival (100% vs. 69.2%; p = 0.004), respectively. In multivariate analysis, high pre-treatment nodal SUVmax (≥ 13.4) was a negative prognostic factor for OS (hazard ratio [HR], 7.799; 95% confidence interval [CI], 1.506–40.397; p = 0.014) and DFS (HR, 9.392; 95% CI, 1.989–44.339; p = 0.005). conclusions High pre-treatment nodal SUVmax was an independent prognosticator of survival and disease progression in nasopharyngeal carcinoma patients treated with IMRT in our cohort. Therefore, nodal SUVmax may provide important information for identifying patients who require more aggressive treatment.

Chemotherapy use and survival in stage II nasopharyngeal carcinoma. Oncotarget 2017; 8:102573-102580. [PMID: 29254272 PMCID: PMC5731982 DOI: 10.18632/oncotarget.21751] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2017] [Accepted: 09/21/2017] [Indexed: 11/25/2022] Open
Abstract
Although common, the use of chemotherapy for stage II nasopharyngeal carcinoma (NPC) is controversial due to its undefined clinical benefits. We therefore conducted a retrospective cohort study to investigate whether chemotherapy confers survival gains to stage II NPC patients. A total of 251 stage II (2010 UICC/AJCC staging system) NPC patients treated between January 2007 and December 2014 were retrospectively analyzed. Patients were matched using the propensity-score matching method. The primary endpoint was overall survival (OS). Secondary endpoints were locoregional-free survival (LRFS) and distant metastasis-free survival (DMFS). Our analyses revealed no significant differences in OS, LRFS, or DMFS for stage II NPC patients treated with radiotherapy (RT) alone, concurrent chemoradiotherapy (CCRT), or CCRT + adjuvant chemotherapy (AC). T2N1 (OR = 6.690; 95% CI, 3.091–14.481) and T1N1 (OR = 5.857; 95% CI, 2.278–15.061) patients were more likely to receive CCRT than T2N0 patients. Similarly, both T2N1 (OR = 10.513; 95% CI, 3.439–32.137) and T1N1 (OR = 7.321; 95% CI, 1.978–27.098) patients were more likely to receive CCRT + AC than T2N0 patients. The present matched survival analysis suggests potential overuse of chemotherapy in stage II NPC, as the addition of chemotherapy did not provide a survival benefit in this group of patients.

Concurrent chemoradiotherapy degrades the quality of life of patients with stage II nasopharyngeal carcinoma as compared to radiotherapy. Oncotarget 2017; 8:14029-14038. [PMID: 28152511 PMCID: PMC5355159 DOI: 10.18632/oncotarget.14932] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2016] [Accepted: 12/28/2016] [Indexed: 11/25/2022] Open
Abstract
The purpose of this study was to compare the quality of life (QoL) of stage II nasopharyngeal carcinoma (NPC) patients treated with radiotherapy (RT) versus concurrent chemoradiotherapy (CCRT). In a cross-sectional study, these patients were treated with RT (n = 55) or CCRT (n = 51) between June 2008 and June 2013. For all subjects, disease-free survival was more than 3 years. QoL was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) questions and the Head and Neck 35 (EORTC QLQ-H&N35) questions. RT had better outcomes than CCRT for global QoL, functional scales, symptom scales of fatigue and insomnia, financial problems, and weight gain. Survivors receiving 1 cycle of concurrent chemotherapy had worse QoL outcomes than survivors receiving 2 cycles of concurrent chemotherapy. Patients receiving 3 cycles of concurrent chemotherapy had the best QoL outcomes. Thus, CCRT adversely affects the QoL of patients with stage II NPC as compared to radiotherapy.

J Cancer 2017; 8:287-297. [PMID: 28243333 PMCID: PMC5327378 DOI: 10.7150/jca.17317] [Citation(s) in RCA: 55] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2016] [Accepted: 10/13/2016] [Indexed: 12/03/2022] Open
Abstract
Background: To explore the value of chemoradiotherapy (CRT) in stage II nasopharyngeal carcinoma (NPC) compared to radiotherapy (RT) alone which includes two-dimensional radiotherapy (2D-RT) and intensity-modulated radiotherapy (IMRT). Methods:All topic-related comparative articles were identified by a comprehensive search of public databases (MEDLINE, EMBASE, Cochrane Library and CBMdisc). The primary outcomes were overall survival (OS), loco-regional relapse-free survival (LRRFS) and distant metastasis-free survival (DMFS). Secondary outcomes were grade 3-4 acute toxicity events. We performed subgroup analysis of CRT versus 2D-RT/IMRT alone to investigate the optimal modality. Sensitivity analysis focused on CRT versus IMRT alone was used to assess stability of the study results. Results:Eleven comparative studies (2138 patients) were eligible. CRT had significantly higher OS (HR = 0.67, 95% CI = 0.45-0.98, P = 0.04) and LRRFS (HR = 0.61, 95% CI = 0.46-0.80, P = 0.0003) than RT alone, but no significant difference was observed in DMFS (HR = 0.83, 95% CI = 0.52-1.31, P = 0.41). Meanwhile, CRT was associated with higher frequencies of grade 3-4 leukopenia, mucositis and nausea (P = 0.005, 0.03, < 0.0001, respectively). Subgroup analysis showed that IMRT alone could achieve equivalent OS, LRRFS and DMFS compared to CRT (P = 0.14, 0.06, 0.89, respectively). Significant value was only observed in LRRFS for CRT compared to 2D-RT alone (P = 0.01). Sensitivity analysis for the comparison of CRT and IMRT alone demonstrated generally stable outcomes, in support of the final conclusions. Conclusions:In the treatment of patients with stage II NPC, CRT was better than 2D-RT alone with significant benefit in LRRFS. IMRT alone was superior to CRT with equivalent survival outcomes and fewer grade 3-4 acute toxicities.

Abstract
OBJECTIVE In our previous work, we incorporated complete blood count (CBC) into TNM stage to develop a new prognostic score model, which was validated to improve prediction efficiency of TNM stage for nasopharyngeal carcinoma (NPC). The purpose of this study was to revalidate the accuracy of the model, and its superiority to TNM stage, through data from a prospective study. METHODS CBC of 249 eligible patients from the 863 Program No. 2006AA02Z4B4 was evaluated. Prognostic index (PI) of each patient was calculated according to the score model. Then they were divided by the PI into three categories: the low-, intermediate-and high-risk patients. The 5-year disease-specific survival (DSS) of the three categories was compared by a log-rank test. The model and TNM stage (7th edition) were compared on efficiency for predicting the 5-year DSS, through comparison of the area under curve (AUC) of their receiver-operating characteristic curves. RESULTS The 5-year DSS of the low-, intermediate-and high-risk patients were 96.0%, 79.1% and 62.2%, respectively. The low-and intermediate-risk patients had better DSS than the high-risk patients (P<0.001 and P<0.005, respectively). And there was a trend of better DSS in the low-risk patients, compared with the intermediate-risk patients (P=0.049). The AUC of the model was larger than that of TNM stage (0.726 vs. 0.661, P=0.023). CONCLUSIONS A CBC-based prognostic score model was revalidated to be accurate and superior to TNM stage on predicting 5-year DSS of NPC.
