Cancer Med 2024; 13:e7029. [PMID: 38396378 PMCID: PMC10891362 DOI: 10.1002/cam4.7029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 02/02/2024] [Accepted: 02/08/2024] [Indexed: 02/25/2024] Open
Abstract
PURPOSE To investigate the correlation between tumor volume reduction rate (TVRR) and prognosis in patients with diverse clinical types of nasopharyngeal carcinoma (NPC) undergoing chemoradiotherapy, thereby aptly categorizing risks and directing the personalized treatment of NPC. MATERIALS AND METHODS A total of 605 NPC patients with varying clinical types were enrolled in this study and subsequently segregated into six subgroups based on their clinical types and TVRR. To accentuate the efficacy of grouping, Groups 1-6 underwent clustered analysis of hazard atio (HR) values pertaining to progression-free survival (PFS), forming three risk clusters denoted as low, intermediate, and high. The log-rank test was employed to discern differences, and R 4.1.1 was utilized for cluster analysis. RESULTS According to survival rates, we classified the first (G2 and G4), second (G1 and G6), and third (G3 and G5) risk clusters as low-, intermediate-, and high-risk, respectively. When comparing risk stratification with the 8th edition of the TNM staging system, our classification exhibited superior predictive prognostic performance. Subgroup analysis of treatments for each risk cluster revealed that the PFS in the neoadjuvant chemotherapy (NACT) + concurrent chemoradiotherapy (CCRT) group surpassed that of the CCRT group significantly (p < 0.05). CONCLUSION The reliance on clinical types and TVRR facilitates risk stratification of NPC during chemoradiotherapy, providing a foundation for physicians to tailor therapeutic strategies. Moreover, the risk cluster delineated for NPC patients during the mid-term of chemoradiotherapy stands as an independent prognostic factor for progression-free survival (PFS), overall survival (OS), distantmetastasis-free survival (DMFS), and local recurrence-free (LRRFS) posttreatment. Additionally, individuals in the high-risk cluster are recommended to undergo adjuvant chemotherapy after CCRT.

Abstract
INTRODUCTION AND AIMS Intensity-modulated radiotherapy (IMRT) is the most commonly used radiotherapy technology in oncology, which enables precise conformation of the radiation dose to the target volume and reduces the risk of radiation damage to the adjacent normal structures. Nevertheless, it is still inevitable for IMRT of head and neck cancer to cause radiation-related toxic and side effects, such as dry mouth, mucositis, oral dysarthria, taste disorder, osteonecrosis, and trismus. Trismus is one of the most common late side effects caused by radiotherapy of nasopharyngeal carcinoma (NPC), which seriously affects the quality of life for patients with NPC. However, the current clinical assessment and management of trismus after radiotherapy for NPC are still imperfect. This best practice implementation project aimed to implement an evidence-based practice in assessing and managing trismus for NPC patients who underwent radiotherapy, thereby improving the compliance of clinical practice with the best evidence and the quality of life of patients with NPC. METHODS This evidence-based audit and feedback project was implemented using a three-phase approach at a third-class hospital in China, following JBI's Practical Application of Clinical Evidence System (PACES) and GRiP evidence application. The first phase included a baseline audit with six evidence-based audit criteria derived from the best available evidence. The second phase included analyzing the results of the baseline audit, identifying barriers to compliance with best practice principles, and developing and implementing strategies to address the barriers identified in the baseline audit. The third phase involved a follow-up audit to assess the results of the interventions implemented to improve practice. RESULTS After evidence application, the compliance rate for audit criterion 1 increased from 0% at baseline audit to 70% at follow-up audit. The compliance rate for audit criterion 2 increased from 0% to 100%. The compliance rate for audit criterion 3 increased from 22 to 62%. The compliance rate for audit criterion 4 increased from 88 to 100%. The compliance rate for audit criterion 5 was 100% at baseline audit and follow-up audit. The compliance rate for audit criterion 6 increased from 0 to 55%. CONCLUSION Implementation of the best evidence for the assessment and management of trismus of patients with NPC after radiotherapy is conducive to improving the compliance of clinical practice with the best evidence, standardizing clinical nursing practice, improving the quality of clinical nursing, and better preventing severe trismus in patients with NPC after radiotherapy.

Treating radiation‑related nasopharyngeal necrosis with endostar in patient with nasopharyngeal carcinoma: A report of two cases and a literature review. Mol Clin Oncol 2023; 19:57. [PMID: 37359714 PMCID: PMC10288433 DOI: 10.3892/mco.2023.2653] [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: 01/25/2023] [Accepted: 05/25/2023] [Indexed: 06/28/2023] Open
Abstract
Radiation-related nasopharyngeal necrosis (RRNN) is a rare and often fatal complication in patients with nasopharyngeal carcinoma (NPC). Currently, no standard treatments are recommended for RRNN. The effects of traditional conservative treatments are suboptimal, and surgery for RRNN cannot be performed by inexperienced doctors. In the present study, the use of Endostar in two patients with RRNN was evaluated. Two patients with RRNN were treated at the Department of Oncology, Panyu Central Hospital (Guangzhou, China). Endostar was administrated (15 mg/day from day 1 to day 7, every three weeks) intravenously for four and seven cycles in a male and a female patient, respectively. The effects of Endostar were assessed using magnetic resonance imaging (MRI) and a nasopharyngoscope. The symptoms of RRNN in both patients were relieved after treatment with Endostar. MRI and nasopharyngoscope analysis revealed that necrosis of the nasopharynx was substantially decreased and nasopharyngeal ulcers were healed. Endostar has the potential to be a novel, effective therapy for the treatment of patients with RRNN. However, clinical trials are required to confirm the results of the present study.

Abstract
BACKGROUND There is no standardized registration frame of cone beam CT (CBCT) in intensity modulated radiotherapy (IMRT) for nasopharyngeal carcinoma (NPC). The overall registration frame that covers the whole head and neck is the most commonly used CBCT registration frame for NPC patients in IMRT. OBJECTIVE To compare the set-up errors using different registration frames of CBCT for NPC to assess the set-up errors for different region of the commonly used clinical overall registration frame. METHODS 294 CBCT images of 59 NPC patients were collected. Four registration frames were used for matching. The set-up errors were obtained using an automatic matching algorithm and then compared. The expansion margin from the clinical target volume (CTV) to the planned target volume (PTV) in the four groups was also calculated. RESULTS The average range of the isocenter translation and rotation errors of four registration frames are 0.89∼2.41 mm and 0.49∼1.53°, respectively, which results in a significant difference in the set-up errors (p < 0.05). The set-up errors obtained from the overall frame are smaller than those obtained from the head, upper neck, and lower neck frames. The margin ranges of the overall, head, upper neck, and lower neck frames in three translation directions are 1.49∼2.39 mm, 1.92∼2.45 mm, 1.86∼3.54 mm and 3.02∼4.78 mm, respectively. The expansion margins calculated from the overall frame are not enough, especially for the lower neck. CONCLUSION Set-up errors of the neck are underestimated by the overall registration frame. Thus, it is important to improve the position immobilization of the neck, especially the lower neck. The margin of the target volume of the head and neck region should be expanded separately if circumstances permit.

Abstract
OBJECTIVE To evaluate the effects of traditional Chinese Baduanjin Qigong exercises on the physical and psychological recovery of patients with nasopharyngeal carcinoma after chemoradiotherapy. METHODS Eighty-eight nasopharyngeal carcinoma patients who had completed chemoradiotherapy were randomly divided into the Baduanjin intervention group (n = 44) and the control group (n = 44). Patients in the intervention group practised Baduanjin exercise for 12 weeks, with the frequency of 40 min a day and 5 days a week after discharge from the hospital. Participants in the control group received usual care. Outcome indicators included quality of life (QOL), complications, cancer-related fatigue (CRF), sleep quality, anxiety, and depression. The intention-to-treat and per-protocol populations were compared using univariate analysis of variance. Partial eta squared was used as a measure of the effect size. RESULTS A total of 75 patients completed the study. In the intention-to-treat analysis, after 12 weeks of exercise intervention, there were significant increases in the global FACT-H&N (95% CI = 2.09 to 11.47, ηp2 = 0.088), social/family well-being (95% CI = 0.13 to 2.26, ηp2 = 0.055), emotional well-being (95% CI = 0.34 to 2.44, ηp2 = 0.074), and head and neck cancer subscale scores (95% CI = 0.17 to 3.86, ηp2 = 0.052) in the Baduanjin group compared with the control group at the 12th week. In the per-protocol analysis, there were significant increases in the global FACT-H&N (95% CI = 4.11 to 11.75, ηp2 = 0.190), physical well-being (95% CI: 0.50 to 3.04, ηp2 = 0.096), social/family well-being (95% CI: 0.32 to 2.15, ηp2 = 0.090), emotional well-being (95% CI: 0.60 to 2.53, ηp2 = 0.125), functional well-being (95% CI: 0.25 to 2.49, ηp2 = 0.075), and head and neck cancer subscale (95% CI: 1.08 to 4.08, ηp2 = 0.139) scores in the Baduanjin group compared with the control group at the 12th week. CONCLUSION The findings in this study indicate that Baduanjin exercise is an effective and appropriate intervention for improving quality of life and is worthy of recommendation and implementation by oncology nurses in the rehabilitation process of patients with nasopharyngeal carcinoma.

Objective Nasopharyngeal carcinoma (NPC) is prevailing in Southern China, characterized by distinct geographical distribution. Aimed to predict the overall survival (OS) of patients with nasopharyngeal carcinoma, this study developed and validated nomograms considering demographic variables, hematological biomarkers, and oncogenic pathogens in China. Methods The clinicopathological and follow-up data of the nasopharyngeal carcinoma patients obtained from a prospective longitudinal cohort study in the Chongqing University Cancer Hospital between Jan 1, 2017 and Dec 31, 2019 (\documentclass[12pt]{minimal}

The calibration curve demonstrated that favorable agreement between the predictions of the nomograms and the actual observations in the training and validation cohorts. In addition, the decision curve analysis proved that the nomogram model had the highest overall net benefit. Conclusion A new prognostic model to predict OS of patients with NPC was developed. This can offer clinicians treatment making and patient counseling. Furthermore, the nomogram was deployed into a website server for use.

Abstract
Purpose To assess the causes of death (COD) and long-term survival after nasopharyngeal carcinoma (NPC) diagnosis. Methods Using linked data from the Surveillance, Epidemiology, and End Results program, patients with NPC diagnosed from 1990 to 2010 and followed up >5 years were identified. Chi-squared test, the Kaplan–Meier method, and the Cox proportional hazard model were used for analyses. Results Among the 3,036 long-term NPC survivors, 1,432 survived for >5–10 years and 1,604 survived for >10 years. The most common COD was primary NPC (36.9%), followed by other causes (28.7%), other cancers (15.3%), cardiac disease (12.9%), and non-malignant pulmonary disease (6.2%). With a median follow-up of 125 months, deaths from NPC decreased with increasing time from diagnosis, while death because of cardiac disease and other causes increased. In those aged <50 years, death due to NPC remained the main COD over time, while cardiopulmonary disease-related death was the leading COD in patients aged ≥50 years. In White patients, death due to NPC decreased, and death due to cardiac disease increased over time. Death from NPC remained significant in Black and Asian patients even 15 years after the diagnosis of NPC, while death due to cardiac disease significantly increased after 9 years of diagnosis in Black patients. Multivariate analyses showed that the independent factors associated with inferior NPC-specific survival were older age, Asians, American Indian/Alaska Native, regional stage, distant stage, and diagnosis in the early years. Conclusions The probability of death from primary NPC remains significant even 15 years after the NPC diagnosis. Our study advocates continued surveillance for NPC survivors beyond the traditional 5 years. Individualized follow-up strategies are required for patients with NPC of different ages and races.

Abstract
Radiotherapy (RT) is one of the most common and effective clinical therapies for malignant tumors. However, there are several limitations that undermine the clinical efficacy of cancer RT, including the low X-ray attenuation coefficient of organs, serious damage to normal tissues, and radioresistance in hypoxic tumors. With the rapid development of nanotechnology and nanomedicine, high-Z nanoradiosensitizers provide novel opportunities to overcome radioresistance and improve the efficacy of RT by deposition of radiation energy through photoelectric effects. To date, several types of nanoradiosensitizers have entered clinical trials. Nevertheless, the limitation of the single treatment mode and the unclear mechanism of nanoparticle radiosensitization have hindered the further development of nanoradiosensitizers. In this review, we systematically describe the interaction mechanisms between X-rays and nanomaterials and summarize recent advances in multifunctional high-Z nanomaterials for radiotherapeutic-based multimodal synergistic cancer therapy. Finally, the challenges and prospects are discussed to stimulate the development of nanomedicine-based cancer RT.
