Abstract
Objective Accurate prognostic predictions and personalized decision-making on induction chemotherapy (IC) for individuals with locally advanced nasopharyngeal carcinoma (LA-NPC) remain challenging. This research examined the predictive function of tumor burden-incorporated machine-learning algorithms for overall survival (OS) and their value in guiding treatment in patients with LA-NPC. Methods Individuals with LA-NPC were reviewed retrospectively. Tumor burden signature-based OS prediction models were established using a nomogram and two machine-learning methods, the interpretable eXtreme Gradient Boosting (XGBoost) risk prediction model, and DeepHit time-to-event neural network. The models' prediction performances were compared using the concordance index (C-index) and the area under the curve (AUC). The patients were divided into two cohorts based on the risk predictions of the most successful model. The efficacy of IC combined with concurrent chemoradiotherapy was compared to that of chemoradiotherapy alone. Results The 1 221 eligible individuals, assigned to the training (n = 813) or validation (n = 408) set, showed significant respective differences in the C-indices of the XGBoost, DeepHit, and nomogram models (0.849 and 0.768, 0.811 and 0.767, 0.730 and 0.705). The training and validation sets had larger AUCs in the XGBoost and DeepHit models than the nomogram model in predicting OS (0.881 and 0.760, 0.845 and 0.776, and 0.764 and 0.729, P < 0.001). IC presented survival benefits in the XGBoost-derived high-risk but not low-risk group. Conclusion This research used machine-learning algorithms to create and verify a comprehensive model integrating tumor burden with clinical variables to predict OS and determine which patients will most likely gain from IC. This model could be valuable for delivering patient counseling and conducting clinical evaluations.

Ding X, Cui X, Cui X, Wang S. Efficacy and toxicities of elective upper-neck irradiation versus whole-neck irradiation of the uninvolved neck in patients with nasopharyngeal carcinoma: A meta-analysis. Radiother Oncol 2023; 188:109860. [PMID: 37625701 DOI: 10.1016/j.radonc.2023.109860] [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: 05/04/2023] [Revised: 07/13/2023] [Accepted: 08/11/2023] [Indexed: 08/27/2023]
Abstract
BACKGROUND This meta-analysis aimed to investigate the efficacy and radiation-related toxicities of upper-neck irradiation (UNI) over whole-neck irradiation (WNI) in patients with unilateral or bilateral node-negative nasopharyngeal carcinoma. METHODS We conducted a systematic review to identify studies comparing survival and toxicities between UNI and WNI by searching key databases up to Aug 2022. Hazard ratios (HRs) with 95% confidence intervals (CIs) for regional recurrence-free survival (RRFS), local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) were pooled using R 4.0.5. Risk ratios (RRs) for acute and late radiation-related toxicities were also pooled. Subgroup analyses according to nodal status, radiotherapy techniques, and study type were conducted. RESULTS Eight studies enrolling 2568 patients were included. Patients who received UNI showed similar RRFS (HR 0.99, 95% CI 0.57-1.74, P = 0.975), LRFS (HR 0.86, 95% CI 0.53-1.41, P = 0.559), DMFS (HR 0.90, 95% CI 0.63-1.29, P = 0.581), PFS (1.10, 95% CI 0.73-1.67, P = 0.642), and OS (1.03, 95% CI 0.77-1.37, P = 0.866) compared with WNI. When stratified by nodal status, the pooled HRs for RRFS in patient subgroups with stage N0 disease, stage N1 with only retropharyngeal lymph nodes metastasis, and unilateral cervical lymph node metastasis were 0.46 (95% CI 0.04-5.16, P = 0.529), 1.12 (95% CI 0.29-4.38, P = 0.872), and 1.02 (95% CI 0.48-2.16, P = 0.968) respectively, none of which reached statistical significance. UNI was associated with lower incidences of grade 1-2 hypothyroidism (RR 0.75, 95% CI 0.57-0.97, P = 0.031) and grade 1-2 dysphagia (RR 0.58, 95% CI 0.42-0.80, P < 0.001) compared with WNI. CONCLUSION UNI had similar efficacy and fewer toxicities compared with WNI for patients with unilateral or bilateral node-negative nasopharyngeal carcinoma. The lower-neck sparing of the uninvolved neck is a valid option for N0, N1, and even unilateral N3 diseases in nasopharyngeal carcinoma.

Abstract
Background To evaluate the long-term survival and treatment-related toxicities of helical tomotherapy (HT) in nasopharyngeal carcinoma (NPC) patients. Methods One hundred and ninety newly diagnosed non-metastatic NPC patients treated with HT from September 2007 to August 2012 were analyzed retrospectively. The dose at D95 prescribed was 70-74Gy, 60-62.7Gy and 52-56Gy delivered in 33 fractions to the primary gross tumor volume (pGTVnx) and positive lymph nodes (pGTVnd), the high risk planning target volume (PTV1), and the low risk planning target volume (PTV2), respectively, using simultaneous integrated boost technique. The statistical analyses were performed and late toxicities were evaluated and scored according to the Common Terminology Criteria for Adverse Events (version 3.0). Results The median follow-up time was 145 months. The 10-year local relapse-free survival (LRFS), nodal relapse-free survival (NRFS), distant metastasis-free survival (DMFS) and overall survival (OS) were 94%, 95%, 86%, and 77.8%; respectively. Fifty (26.3%) patients had treatment-related failures at the last follow-up visit. Distant metastasis, occurred in 25 patients, was the major failure pattern. Multivariate analysis showed that age and T stage were independent predictors of DMFS and OS, Concomitant chemotherapy improved overall survival, but anti-EGFR monoclonal antibody therapy failed. The most common late toxicities were mainly graded as 1 or 2. Conclusions Helical tomotherapy with simultaneous integrated boost technique offered excellent long-term outcomes for NPC patients, with mild late treatment-related toxicities. Age and clinical stage were independent predictors of DMFS and OS. And, concurrent chemotherapy means better OS. Further prospective study is needed to confirm the superiority of this technology and to evaluate the roles of anti-EGFR monoclonal antibody treatment.

Explore the Value of Adding Induction Chemotherapy to Concurrent Chemoradiotherapy in T3-4N0M0 Nasopharyngeal Carcinoma Patients: A Retrospective Study. Cancer Manag Res 2021; 13:7067-7076. [PMID: 34526821 PMCID: PMC8437383 DOI: 10.2147/cmar.s321471] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Accepted: 08/16/2021] [Indexed: 12/09/2022] Open
Abstract
Purpose Patients with T3-4N0M0 nasopharyngeal carcinoma (NPC) are a unique subgroup of locoregional advanced NPC, which generally have a better prognosis than others and are often excluded in most randomized controlled clinical trials focusing on locoregional advanced NPC. The management of this population is still controversial. This study aims to evaluate the outcomes of T3-4N0M0 NPC patients treated with sequential induction chemotherapy and concurrent chemoradiotherapy (IC+CCRT) or chemoradiotherapy (CCRT) alone. Patients and Methods We included 362 patients diagnosed with T3-4N0M0 NPC from two hospitals between December 2005 and December 2014. All patients were received IC + CCRT (n=146) or CCRT (n=216). Locoregional failure-free survival (LRFFS), distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS) were retrospectively estimated. Results The median follow-up was 95 (range: 11-168) months. Univariable analyses have shown that 5-year LRFFS, DFS and OS in the IC+CCRT group and the CCRT group were 87.4% vs 93.4% (P = 0.035), 80.4% vs 87.0% (P = 0.047) and 86.3% vs 93.0% (P = 0.040). Multivariate analyses demonstrated that only the T stage was the independent prognostic factor for LRFFS, DFS, and OS in the entire group analysis. Subgroup analysis revealed that patients with T3 tumors who received IC+CCRT had significantly lower LRFFS, DFS, and OS than those treated with CCRT. For T4 patients, the outcomes had no significant difference between the two groups. Conclusion This retrospective study showed that T3N0M0 patients who received CCRT had better prognosis than those treated with IC+CCRT. In terms of T4N0M0 disease, treatment outcomes are similar in both treatment groups. However, these results require further confirmation of large sample size, prospectively, randomized controlled trials.

Abstract
Up to 85% of the patients with nasopharyngeal carcinoma present with regional nodal metastasis. Although excellent nodal control is achieved with radiotherapy, a thorough understanding of the current TNM staging criteria and pattern of nodal spread is essential to optimize target delineation and minimize unnecessary irradiation to adjacent normal tissue. Selective nodal irradiation with sparing of the lower neck and submandibular region according to individual nodal risk is now emerging as the preferred treatment option. There has also been continual refinement in staging classification by incorporating relevant adverse nodal features. As for the uncommon occurrence of recurrent nodal metastasis after radiotherapy, surgery remains the standard of care.

Abstract
PURPOSE To identify whether chemoradiotherapy improves survival in patients with stage T3-4N0M0 nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS The data of patients with stage T3-4N0M0 NPC were extracted from the Surveillance, Epidemiology, and End Results database between 2004 and 2016. The patients were divided into radiotherapy and chemoradiotherapy groups. Overall survival (OS) and cancer-specific survival (CSS) were assessed using the Kaplan-Meier method and propensity score matching (PSM) analyses. RESULTS We examined 496 patients: 88 who received radiotherapy and 408 who received chemoradiotherapy. Before PSM, chemoradiotherapy was associated with a better 5-year OS (52.58% vs. 38.13%; P = .005) and similar CSS (63.62% vs. 59.26%; P = .196) compared to those associated with radiotherapy. However, chemoradiotherapy was not an independent prognostic factor for OS [hazard ratio (HR)=0.95, 95% confidence interval (CI): 0.68-1.32; P = .760] or CSS (HR = 1.02, 95% CI: 0.66-1.56; P = .935). After PSM, similar OS (45.15% vs. 42.78%; P = .626) and CSS (58.22% vs. 60.37%; P = .730) were found between the radiotherapy and chemoradiotherapy groups. CONCLUSION Radiotherapy and chemoradiotherapy are associated with similar OS and CSS in patients with stage T3-4N0M0 NPC.

Abstract
BACKGROUND To evaluate the failure patterns and prognostic factors in patients with cervical node-negative nasopharyngeal carcinoma (NPC) in the intensity-modulated radiotherapy (IMRT) era. METHODS Patients with cervical node-negative NPC treated with IMRT at the Sun Yat-sen University Cancer Center between February 2001 and December 2008 were retrospectively reviewed. The failure patterns, prognostic factors, and efficacy of additional chemotherapy were assessed. RESULTS The median follow-up time was 78 months for 298 patients. The 5-year local recurrence-free survival (LRFS), nodal recurrence-free survival (NRFS), distant metastasis-free survival (DMFS), failure-free survival (FFS), and overall survival (OS) were 95.2%, 99.3%, 94.8%, 89.8%, and 92.9%, respectively. The rate of treatment failure remained high in patients with T4 disease (35.4%, 17/48), including eight of local recurrence, two of nodal recurrence, and seven of distant metastasis. Multivariate analyses showed that the primary gross tumor volume (GTVp) was significantly associated with LRFS, DMFS, FFS, and OS. Subgroup analysis revealed that patients with GTVp ≤ 42.5 cc had better 5-year LRFS (98.7% vs 81.4%, P < .001), 5-year DMFS (97.8% vs 82.5%, P < .001), 5-year FFS (96.1% vs 65.4%, P < .001), and 5-year OS (96.6% vs 78.2%, P < .001) than patients with GTVp > 42.5 cc. However, additional chemotherapy showed no significant survival benefit in stratification analysis. CONCLUSIONS Cervical node-negative NPC has a good prognosis in the IMRT era, and the primary tumor volume is the most important prognostic factor. Further exploration is needed to determine the optimal treatment strategy for patients with a high tumor burden.

Abstract
Purpose Nasopharyngeal carcinoma (NPC) is a central tumor with a rich lymphatic
network and a propensity for bilateral cervical lymph node metastasis. There
is an orderly pattern of lymph node involvement in NPC. There is no current
standard for prophylactic neck irradiation in node-negative or limited
retropharyngeal (RP) node–positive NPC. This study aims to synthesize
the current evidence on upper neck irradiation (UNI) versus whole neck
irradiation (WNI) as prophylactic neck irradiation in node-negative or
limited RP node–positive NPC. Materials and Methods A search of relevant articles was done from 2000 to October 2015. Critical
appraisal and meta-analysis of the eligible studies were undertaken to
assess the effectiveness of UNI versus WNI as prophylactic neck irradiation
in node-negative or limited involved RP node NPC. Results Only one randomized controlled trial investigated the use of prophylactic UNI
versus WNI and showed no confirmed nodal relapse in both arms. Pooled
analysis of four retrospective studies showed no significant difference in
nodal recurrence, whether in-field or out-of-field recurrence. There was
also no significant difference in terms of 5-year distant
metastasis–free and overall survival. Conclusion In node-negative or limited RP node–positive NPC, the current evidence
shows the possibility of treating only the upper neck (levels II, III, and
VA) without compromising nodal control, distant metastasis, and overall
survival. As a result of the scarcity of data, more randomized clinical
trials are warranted in this subset of patients.

Feasibility of ipsilateral lower neck sparing irradiation for unilateral or bilateral neck node-negative nasopharyngeal carcinoma: systemic review and meta-analysis of 2, 521 patients. Radiat Oncol 2018; 13:141. [PMID: 30081932 PMCID: PMC6080384 DOI: 10.1186/s13014-018-1087-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2018] [Accepted: 07/25/2018] [Indexed: 11/26/2022] Open
Abstract
Background To compare the efficacy of ipsilateral lower neck sparing irradiation (ILNSI) versus ipsilateral lower neck prophylactic irradiation (ILNPI) for unilateral or bilateral neck node-negative nasopharyngeal cancer (NPC). Methods A comprehensive literature search of PubMed, EMBASE, the Cochrane Library and other public databases was conducted in October, 2017. The outcomes were 3-year overall/regional recurrence-free/disease-free/distant metastasis-free survival (OS/RRFS/DFS/DMFS) and ipsilateral lower neck (ILN) recurrence. We performed subgroup analysis of ILNSI versus ILNPI for different radiotherapy techniques. Sensitivity analysis was performed to examine the stability of the results. Results Nine head-to-head comparative studies (2, 521 patients) were included in the meta-analysis. For the comparison of ILNSI versus ILNPI, there was no significant difference in 3-year OS (HR = 1.16, 95% confidence interval [CI] = 0.85–1.58, P = 0.36), RRFS (HR = 1.37, 95% CI = 0.76–2.47, P = 0.30), DFS (HR = 1.08, 95% CI = 0.80–1.44, P = 0.62) and DMFS (HR = 1.00, 95% CI = 0.69–1.44, P = 0.99). ILNSI and ILNPI also led to equivalent ILN recurrence rates (OR = 0.98, 95% CI = 0.47–2.03, P = 0.96). No significant heterogeneity was observed for any outcome. Subgroup analysis confirmed no significant differences between ILNSI and ILNPI for any outcome, regardless of radiotherapy technique. Sensitivity analysis indicated all outcomes were highly stable in favor of the original conclusions. Conclusions ILNSI provided equivalent survival outcomes and regional control compared to ILNPI; ILNSI represents an appropriate alternative strategy for patients with unilateral or bilateral neck node-negative NPC.

Abstract
BACKGROUND Regenerating gene IA (REGIA) plays an important role in tissue regeneration and tumors prognosis of epithelium origin. However, the role of REGIA in nasopharyngeal carcinoma (NPC) is unclear. This study aims to investigate the expression and function of REG1A in NPC. RESULTS We have found that there was 63 patients with REGIA positive expression of 155 patients in this study (40.65%). The positive expression rate of REGIA was 30.50, 44.44 and 47.83% in stage T2, T3 and T4 patients, respectively. The REGIA expression was significantly difference in T2 and T4 stage tumors or T2 and T3-T4 stage. The positive expression rate of REGIA was found to be higher in patients with cervical lymph node persistence than those with cervical lymph node complete regression. Patients with negative REGIA expression had a better overall survival and free survival than those with REGIA positive expression. In addition, according to the univariate and multivariate analysis, the REGIA expression was an independent adverse prognostic factor for NPC patients. CONCLUSION REGIA expression was a useful biomarker in NPC patients for assessing T stage and survival.

Abstract
Nasopharyngeal carcinoma (NPC), a tumor arising from the epithelial cells of the nasopharynx, is endemic in Southeast Asia and Taiwan. The prognosis of NPC patients with local recurrence and metastasis is poor. Resistance to anoikis is a primary characteristic of tumor cells that metastasize. However, the mechanism through which NPC cells resist anoikis and are able to metastasize has not been fully elucidated. In the present study, the acquisition of anoikis resistance was analyzed in the TW01 and TW06 human NPC cell lines growing under anchorage-independent conditions. A considerable number of TW01 and TW06 cells was found to be resistant to anoikis and exhibited a higher capability of migration and invasion. These anoikis-resistant NPC cells exhibited significantly increased expression of signal transducer and activation of transcription 3 (Stat3) compared with adherent cells. Furthermore, blockade of STAT3 expression by STAT3 inhibitors or STAT3 silencing significant increased anoikis in anoikis-resistant NPC cells. Moreover, silencing STAT3 not only reduced the capacity of NPC cells to resist anoikis, but also reversed their invasive properties. The expression of epithelial‑to-mesenchymal transition‑related proteins and CD44 was also significantly decreased following STAT3 knockdown. The results of the present study established that STAT3 mediates anoikis resistance, with enhanced cell migration and invasion of NPC cells, and that activation of STAT3 may increase metastatic capacity, indicating the crucial role of STAT3 in conferring anoikis resistance and enhanced invasive properties to NPC cells.

Abstract
BACKGROUND Recurrent nasopharyngeal carcinoma (NPC) after previous radiotherapy is challenging. There is no standard approach for salvage treatment. Here we present toxicity and treatment results for recurrent NFC patients who underwent fractionated stereotactic radiotherapy (FSRT) as second line radiotherapy (RT). MATERIALS AND METHODS Between April 2009 and July 2012, 24 patients, with a male to female ratio of 3:1, were treated with CykerKnife® FSRT for recurrent NFC in our institution. Seven out of 24 patients had metastatic recurrent disease. Median age was 53 years (range, 20-70 years). Initial RT dose was 70Gy. The time period between initial RT and FSRT was a median of 33.2 months. The median prescription dose for FSRT was 30Gy (range, 24-30 Gy) in a median of 5 fractions (range, 4-6). RESULTS The median follow-up for all patients was 19.5 months (IQR: 12.2. -29.2 months). The locoregional control; progression free survival and overall survival (OS) rates for 1-, 2- and 3-year were 64%, 38%, 21%; 60%, 30%, 17% and 83%, 43%, 31%, respectively. Median OS for the entire cohort was 22 months (95% CI: 16.5-27.5). On multivariate analysis recurrent tumor stage was the only prognostic factor for OS (p=0.004). One patient exhibited grade III temporal lobe necrosis. One died because of grade IV mucositis and overlapping infection. CONCLUSIONS The treatment of recurrent NPC is controversial. Fractionated stereotactic radiotherapy is promising. However, the published trials are heterogeneous with respect to the selection criteria and treatment details. Prospective studies with long term follow-up data are warranted.

Abstract
Background Numerous studies have generated promising but incomplete evidence for the prognostic value of pretreatment serum levels of lactate dehydrogenase (S-LDH) in nasopharyngeal carcinoma (NPC). Methods Pretreatment serum levels of S-LDH in 601 patients with NPC were measured before treatment, and their associations with overall survival and tumor-free survival were studied. Univariate and multivariate analysis of subgroups was used to evaluate the prognostic value of S-LDH in early-stage and late-stage NPC separately. Results Pretreatment S-LDH levels were significantly lower in T1+2 patients than in T3+4 patients, lower in N0+1 patients than in N2+3 ones, and lower in stage I + II patients than in III + IV ones. Multivariate analysis showed that among patients with late-stage NPC, high pretreatment S-LDH levels >225 U/L were an independent predictor of poor overall survival and tumor-free survival. Among patients with early-stage NPC, pretreatment S-LDH levels >171 U/L, which overlap with the normal range, were an independent predictor of shorter overall survival and tumor-free survival. Conclusion Pretreatment S-LDH levels may be a reliable biomarker for predicting the long-term prognosis of patients with early-stage or late-stage NPC.

Abstract
BACKGROUND This study sought to compare the clinical outcomes of upper versus whole-neck prophylactic irradiation in the treatment of patients with node-negative nasopharyngeal carcinoma (NPC). METHODS Between November 2005 and June 2012, 301 patients with node-negative NPC were randomly assigned to receive primary plus prophylactic upper neck irradiation (UNI, 153 patients) or primary plus whole-neck irradiation (WNI, 148 patients). Patients in both groups received irradiation to the primary tumor and the upper neck nodal regions, and patients in the WNI group also received irradiation to the lower neck. The main endpoint of the study was to compare the lower neck control rate between the 2 groups. RESULTS With a median follow-up period of 39 months (range, 6-84 months), no patient in either group had a cervical node relapse. The overall survival at 3 years was 89.5% (95% confidence interval [CI] = 84.1%-95.0%) in the UNI group and 87.4% (95% CI = 81.4%-93.5%) in the WNI group (hazard ratio [HR] = 0.866, 95% CI = 0.41-1.82; P = .70). The 3-year relapse-free survival rate was 89.8% and 89.3% (95% CI = 84.2%-95.3% and 83.7%-94.8%, HR = 0.914, 95% CI = 0.42-2.00; P = .82), and the 3-year metastasis-free survival rate was 91.7% and 90.9% (95% CI = 87.0%-96.5% and 85.7%-96.1%) for the UNI and WNI groups, respectively (HR = 1.007, 95% CI = 0.44-2.32; P = .99). CONCLUSIONS Prophylactic upper neck irradiation is sufficient for patients with node-negative NPC.
