[PMID: 36420965 DOI: 10.1002/hed.27253] [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: 05/09/2022] [Revised: 10/25/2022] [Accepted: 11/09/2022] [Indexed: 11/25/2022] Open
Abstract
The present study aimed to evaluate the effectiveness and safety of various salvage treatments to treat locally recurrent nasopharyngeal carcinoma (IrNPC). A comprehensive search was conducted to gather relevant research publications on salvage treatment for IrNPC. Specifically, 2-, 3-, and 5-year overall survival were the primary outcome. A total of 89 studies with 101 cohorts were collected. Endoscopic nasopharyngectomy was found to be associated with a significantly improved 5-year OS compared with CRT (p = 0.027) and IMRT (p = 0.016). Moreover, based on recurrence T classification, the 2-, 3-, and 5-year OS were similar across different treatments. Endoscopic nasopharyngectomy was associated with a significant reduction in treatment-related complications (grade ≥ 3) compared with IMRT (p < 0.001) and open nasopharyngectomy (p = 0.028). Endoscopic nasopharyngectomy may provide comparable treatment outcomes to re-irradiation, while offering a better safety profile for selective patients with resectable IrNPC.

Association of Systemic Inflammation and Malnutrition With Survival in Nasopharyngeal Carcinoma Undergoing Chemoradiotherapy: Results From a Multicenter Cohort Study. Front Oncol 2021; 11:766398. [PMID: 34765561 PMCID: PMC8576523 DOI: 10.3389/fonc.2021.766398] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2021] [Accepted: 10/06/2021] [Indexed: 01/20/2023] Open
Abstract
Background Malnutrition and systemic inflammation are common in patients with nasopharyngeal carcinoma (NPC). The Patient-Generated Subjective Global Assessment (PG-SGA) score and neutrophil-to-lymphocyte ratio (NLR) reflect the integrated nutritional status and inflammatory level of patients with NPC, respectively. We performed this study to identify whether NLR and PG-SGA score are associated with outcome and survival time for patients with NPC undergoing chemoradiotherapy. Methods The multicenter cohort study included 1,102 patients with NPC between June 2012 and December 2019. The associations of all-cause mortality with NLR and PG-SGA score were calculated using the Kaplan–Meier method and the log-rank test. We also did a multivariate-adjusted Cox regression analysis to identify the independent significance of different parameters. Restricted cubic spline regression was carried out to evaluate the association between NLR and overall survival (OS). A nomogram was established using the independent prognostic variables. Interaction terms were used to investigate whether there was an interactive association between NLR and PG-SGA. Results A total of 923 patients with NPC undergoing chemoradiotherapy were included in this study: 672 (72.8%) were males and 251 (27.2%) were females, with a mean age of 49.3 ± 11.5 years. The Kaplan–Meier curves revealed that patients with malnutrition (PG-SGA score >3) had worse survival than patients who were in the well-nourished group (PG-SGA score ≤3) (p < 0.0001). In addition, patients in the high NLR group (NLR ≥ 3) had worse survival than those in the low NLR group (NLR < 3) (p < 0.0001). Patients with high PG-SGA and high NLR had the worst survival (p < 0.0001). An increase in NLR had an inverted L-shaped dose–response association with all-cause mortality. A nomogram was developed by incorporating domains of NLR and PG-SGA score to accurately predict OS 12–60 months for patients [the C-index for OS prediction of nomogram was 0.75 (95% CI, 0.70–0.80)]. The interaction of PG-SGA with NLR was significant (p = 0.009). Patients with high PG-SGA and high NLR had a nearly 4.5-fold increased risk of death (HR = 4.43, 95% CI = 2.60–7.56) as compared with patients with low PG-SGA and low NLR. Conclusions Our study provided clear evidence that high PG-SGA score and high NLR adversely and interactively affects the OS of patients with NPC undergoing chemoradiotherapy.

The development of a nomogram to predict post-radiation necrosis in nasopharyngeal carcinoma patients: a large-scale cohort study. Cancer Manag Res 2019; 11:6253-6263. [PMID: 31372033 PMCID: PMC6626898 DOI: 10.2147/cmar.s197841] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Accepted: 04/30/2019] [Indexed: 12/20/2022] Open
Abstract
Objective: This study aimed to establish a nomogram to predict the risk of post-radiation necrosis in nasopharyngeal carcinoma (NPC) patients. Background: This study was performed to identify influencing factors for developing post-radiation necrosis, and to establish an effective nomogram model to predict individual risks in NPC patients. Methods: 7144 NPC patients receiving radical radiotherapy from 2007 to 2012 were involved in the study, and 207 of them developed nasopharyngeal necrosis (NPN). The clinical characteristics and baseline laboratory results were collected and analyzed. Independent predictive factors were selected using the Cox proportional model and incorporated into the nomogram. The receiver operating characteristic curve and the calibration curve were used to verify discrimination and calibration. Results: The experience of re-irradiation contributed most to the occurrence of NPN (HR, 15.56, 95% CI 10.84–22.35, p<0.001). Clinical factors including age, pathology type, history of diabetes, and original T stage were independent predictors of NPN. Factors reflecting patients’ baseline nutritional and inflammatory status such as hemoglobin, albumin, and C-reactive protein were also significantly associated with the development of NPN. With all independent predictive factors incorporated, a nomogram was generated, and it showed excellent discrimination and calibration. Conclusion: This study was the first large-scale cohort study focusing on the development of NPN and established a nomogram to predict its occurrence based on the clinical and laboratory indicators. The nomogram demonstrated good discriminative capacity and satisfactory agreement, which would offer valuable clues for clinicians to distinguish the high-risk NPN population and maintain close surveillance.

Detection and clinical significance of circulating tumor cells in patients with nasopharyngeal carcinoma. Oncol Lett 2019; 18:2537-2547. [PMID: 31452741 DOI: 10.3892/ol.2019.10560] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2017] [Accepted: 09/28/2018] [Indexed: 12/11/2022] Open
Abstract
Nasopharyngeal carcinoma (NPC) is the most common cancer type originating in the nasopharynx, and varies notably from other cancer types of the head and neck in its occurrence, causes, clinical behavior and treatment. Significant effort has been made into understanding the biological properties of circulating tumor cells (CTCs), with previous studies demonstrating the critical role CTCs serve in the metastatic spread of carcinoma. However, associations between NPC and CTCs have not been completely elucidated. Therefore, in the present study, the CanPatrol™ CTC-enrichment technique and classical in situ hybridization assay were utilized to acquire, identify and classify CTCs from patients with NPC. Subsequently, the correlation between CTCs and the clinical indexes, progression-free survival (PFS), N-cadherin gene expression and the response to therapy were investigated. The present study then determined whether the Wnt/β-catenin signaling pathway served a role in therapy for NPC cells. Collectively, the research demonstrated that CTCs could be detected in patients with NPC. Additionally, CTCs exhibited a statistically significant association with the Epstein-Barr virus infection prior to therapy and Eastern Cooperative Oncology Group score following therapy. Furthermore, co-treatment with cisplatin and paclitaxel significantly decreased the number of CTCs. In addition, mesenchymal CTCs may serve as a predictor of PFS. Finally, the present study demonstrated that cisplatin combined with paclitaxel induced apoptosis and decreased the tumor markers in NPC cells through the Wnt/β-catenin signaling pathway. In conclusion, these data indicated that CTCs may serve as a biomarker in monitoring the therapeutic efficacy of treatments for NPC. Furthermore, the Wnt/β-catenin signaling pathway served a therapeutic role in the treatment of NPC.

Abstract
INTRODUCTION While the optimal target volumes for primary nasopharyngeal tumour are still subject to debate, we evaluated primary tumour volumes in nasopharyngeal carcinoma (NPC) patients treated according to an institutional protocol with a reduced volume approach and compared them to those determined by Radiation Therapy Oncology Group (RTOG)-0615 guidelines. METHODS This single-centre retrospective analysis included 36 NPC patients treated between 2/2007 and 3/2014. Planning target volume (PTV)-P 50 (50 Gy isodose to the primary tumour) included the gross tumour and the entire nasopharyngeal mucosa (clinical target volume [CTV]-P 50) with 5 mm margins. The PTV-P 50 volumes, as determined by our protocol, were compared to those obtained with RTOG-0615 PTV-P 59.4 (59.4 Gy to the primary tumour). Clinical outcomes were also analysed. RESULTS Median (range) follow-up: 48 (21-108) months; 88.9% were males; median age was 53 (27-86) years; 14%, 53%, and 33% had stage II, III, and IV disease at diagnosis, respectively. Median volume of PTV-P 50: 209.0 (92.6-568.0) cc. Median volume of RTOG-0615 PTV-P 59.4-P: 292.0 (123.6-425.1) cc. The PTV-P volume was significantly smaller than that delineated according to the RTOG-0615 protocol (p < 0.001). Isolated local relapse as first site of recurrence occurred in five patients: two with stage III, two with IVA and one with IVB disease; all had advanced local disease at diagnosis. All local recurrences occurred in the PTV-P 69-70 region. CONCLUSION A reduced volume approach for radiotherapy in primary NPC provided acceptable long-term local control.

Abstract
Purpose: The study evaluated the feasibility, clinical effectiveness, and quality of life of computed tomography (CT)-guided 125I brachytherapy for locally recurrent nasopharyngeal carcinoma (NPC). Methods: We recruited 81 patients diagnosed with locally recurrent NPC after previous radiotherapy with or without chemotherapy. Thirty-nine patients received 125I brachytherapy (group A) and 42 received re-irradiation (IMRT, group B). The evaluated outcomes were local control, complications, and quality of life. Cox proportional hazards regression analysis was used to compare local tumor progression-free survival (LTPFS) and overall survival (OS) in the two treatment groups. Results: The median follow-up was 30 months (range, 5-68 months), median LTPFS was 21 in group A and 17 months in group B. The 1-, 2-, and 3-year OS in group A were 84.6%, 51.3%, 30.7%, and 85.7%, 50.0%, and 32.6% in group B. In group A, 10/39 patients (25.6%) experienced at least one ≥grade III complication; no grade V complications occurred. In group B, 28/42 (66.7%) experienced at least one ≥grade III complication and 6/42 (14.3%) died of severe grade V complications. No significant between-group difference existed in the Quality of Life score on the EORTC QLQ-H&N35 questionnaire before treatment. In group A, quality of life was significantly improved after treatment; but did not improve, or even deteriorated in group B. Conclusions: 125I brachytherapy was a feasible, safe, and effective treatment for locally recurrent NPC. 125I brachytherapy significantly reduced complications caused by re-irradiation and improved patients' quality of life.

Long-term outcomes of a phase II randomized controlled trial comparing intensity-modulated radiotherapy with or without weekly cisplatin for the treatment of locally recurrent nasopharyngeal carcinoma. CHINESE JOURNAL OF CANCER 2016; 35:20. [PMID: 26879049 PMCID: PMC4753647 DOI: 10.1186/s40880-016-0081-7] [Citation(s) in RCA: 44] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/10/2015] [Accepted: 09/01/2015] [Indexed: 11/28/2022]
Abstract
Background
Salvage treatment for locally recurrent nasopharyngeal carcinoma (NPC) is complicated and relatively limited. Radiotherapy, combined with effective concomitant chemotherapy, may improve clinical treatment outcomes. We conducted a phase II randomized controlled trial to evaluate the efficacy of intensity-modulated radiotherapy with concomitant weekly cisplatin on locally recurrent NPC. Methods
Between April 2002 and January 2008, 69 patients diagnosed with non-metastatic locally recurrent NPC were randomly assigned to either concomitant chemoradiotherapy group (n = 34) or radiotherapy alone group (n = 35). All patients received intensity-modulated radiotherapy. The radiotherapy dose for both groups was 60 Gy in 27 fractions for 37 days (range 23–53 days). The concomitant chemotherapy schedule was cisplatin 30 mg/m2 by intravenous infusion weekly during radiotherapy. Results The median follow-up period of all patients was 35 months (range 2–112 months). Between concomitant chemoradiotherapy and radiotherapy groups, there was only significant difference in the 3-year and 5-year overall survival (OS) rates (68.7% vs. 42.2%, P = 0.016 and 41.8% vs. 27.5%, P = 0.049, respectively). Subgroup analysis showed that concomitant chemoradiotherapy significantly improved the 5-year OS rate especially for patients in stage rT3–4 (33.0% vs. 13.2%, P = 0.009), stages III–IV (34.3% vs. 13.2%, P = 0.006), recurrence interval >30 months (49.0% vs. 20.6%, P = 0.017), and tumor volume >26 cm3 (37.6% vs. 0%, P = 0.006). Conclusion Compared with radiotherapy alone, concomitant chemoradiotherapy can improve OS of the patients with locally recurrent NPC, especially those with advanced T category (rT3–4) and stage (III–IV) diseases, recurrence intervals >30 months, and tumor volume >26 cm3.

Abstract
The nasopharyngeal cancer is a common cancer among southern Chinese. In order to better understand molecular mechanism of recurrent nasopharyngeal cancer (rNPC), we used DNA microarray to identify down-regulated tumor suppressed genes (TSGs) in rNPC, and bioinformatics to analyze their chromosomal localizations and molecular functions. Eight non-recurrent nasopharyngeal cancer (nNPC) and six rNPC tissue samples were selected, and Affymetrix Gene1.0 ST chips were used to construct the expression profiling of each tissue sample. Identify the down-regulated TSGs in rNPC by comparing expression profiling data of two type tissue samples. A total of five TSGs were identified to be down-regulated in rNPC. These five TSGs include SERPINF1, TPD52L1, FBLN1, RASSF6, and S100A2, and Signal Log Ratio were -2.2, -2.3, -3.5, -3.9 and -6.9 respectively. Chromosomal localization analysis showed that S100A2, RASSF6, TPD52L1, SERPINF1, and FBLN1 were located on chromosomes 1q, 4q, 6q, 17p and 22q, respectively. Functional analysis showed that SERPINF1 and TPD52L1 belonged to enzyme activity genes, S100A2 and FBLN1 belonged to calcium ion binding genes, RASSF6 belong to protein binding genes. Five TSGs likely to be the candidate TSGs involved in rNPC, and may play important roles in occurrence of rNPC. Chromosomes 1q, 4q, 6q, 17p and 22q may be considered as important region for screening TSGs that may relevant to rNPC. Those genes and chromosomal region need to be further studied.

Abstract
OBJECTIVES Providing the primary recurrence is localized, salvage treatment is possible for nasopharyngeal carcinoma (NPC). This is a review of the experience of retreatment of this malignancy highlighting the roles of surgery and repeat radiotherapy. METHODS The Tumor Registry of the Prince of Wales Cancer Centre was audited for patients with an initial diagnosis of squamous/nonsquamous cell NPC who had primary treatment with radiotherapy, and now presented for retreatment. Features relating to patient, disease and treatment factors were evaluated. The primary end point was subsequent local control, and secondary endpoints were overall and cancer-specific survival. RESULTS Over a 30-year period 39 patients were eligible, with 25 receiving both primary and retreatment at Prince of Wales Hospital. There were 25 males and 14 females with a median age of 50 years. Thirty-six patients had radiotherapy, 4 had stereotactic radiosurgery, 5 had brachytherapy, and the remainder had external treatment. Surgery was performed in 10 patients, of whom 3 had this as the only retreatment modality. Radiotherapy doses for retreatment ranged from 15 Gy (stereotactic radiosurgery) to 71.28 Gy (mean fractionated dose). Local control was achieved in 16 patients giving an overall rate of 41.0%, and the 5-year overall survival rate was 33.3%. Treatment modality was a significant prognostic factor for local control (P < 0.001) and cancer-specific survival (P < 0.05). CONCLUSION The presence of local recurrence after definitive treatment of NPC may still be salvageable. The best outcomes with reirradiation occur in the context of limited volume recurrence and a disease-free interval greater than 18 months.

Abstract
INTRODUCTION The practice of image-based three dimensional treatment planning and conformal radiotherapy techniques offer the opportunity to elaborate novel treatment forms, e.g. repeat irradiation techniques for primary brain tumours. AIM The authors analysed the effect on survival and toxicity of fractionated external beam repeat irradiation in brain tumour patients. METHODS At the National Institute of Oncology, between 2002 and 2006, fractionated external beam repeat irradiation was performed in eleven patients with recurrent primary brain tumour, with total of 50-54 Gy or near total of 34-40 Gy doses. All patients were previously treated with total radiotherapy doses of 50-64 Gy. The intervals between radiotherapy courses were in the range of 7-30 years. All the treatments were carried out with 3D image-based conformal methods, the fractionation was conventional, with 1,8-2,0 Gy daily fractions in all cases. RESULTS The repeat irradiation was tolerated well in the material. No grade 3-4 acute toxicity was detected, and serious, grade 3 mental deterioration, not related tumour progression was observed in only one case. In one case reoperation was necessary due to histologically verified radio-necrosis with mass-effect, and we believe that late neurotoxicity caused serious functional inabilities in one case. The median progression free survival was 8 (2-33) months, the median survival was 13 (4,5-33) months. Three of our patients were alive at the end of the study. CONCLUSIONS Based on this experience and current knowledge, in absence of other treatment possibilities, the fractionated external beam repeat irradiation with near total doses could be a therapeutic choice in case of recurrent primary brain tumours, if having appropriate background. To define the optimal treatment strategy and regimens, further clinical trials should be carried out.

Abstract
AIMS To investigate prospectively the feasibility and efficacy of dose escalation using three-dimensional conformal radiotherapy (3D-CRT) boost technique for locally recurrent nasopharyngeal carcinoma (NPC) in a randomised study. MATERIALS AND METHODS Thirty-six patients with locally recurrent NPC (>6 months interval from previous radical radiotherapy, no cervical lymph-node involvement and no distant metastasis) were enrolled. Treatment included conventional external-beam radiotherapy to 54 Gy, followed by a 3D-CRT boost to the gross tumour region. Patients were randomised to three boost dose levels: 16 Gy, 20 Gy and 24 Gy for groups I, II and III, respectively, with 12 patients in each group. All boost doses were delivered in 4-Gy fractions and 3 fractions per week. Median follow-up was 27 months (range 14-44 months). RESULTS Three-year, local-recurrence-free survival rate was significantly higher (72%) for the high-dose group III than for groups I and II (37% and 28%, respectively, P = 0.047). No significant difference was found in the 3-year overall survival rate among the three groups (72%, 59% and 82% for groups I, II and III, respectively). Three-year distant metastases rates were 17%, 0% and 18%, respectively. Skull-base invasion (P = 0.017) and pathology (P = 0.0006) correlated with overall survival. Treatment was well tolerated and no significant difference was observed among the three groups in acute and late toxicities (grade III toxicity is minimal: 17%, 17%, 0% of oral mucositis and 25%, 17%, 17% of nasopharyngeal mucositis in groups I, II, III, respectively, and 8% leukocytopenia only in group II; no grade IV toxicity occurred in any of the groups except for a fatal bleeding in group III). CONCLUSIONS Re-irradiation with high-dose 3D-CRT boost technique results in high local control rate and acceptable toxicity in patients with recurrent NPC. Dose escalation to the boost volume to 78 Gy (54 Gy + 24 Gy boost) results in improved recurrence-free survival compared with lower doses.
