Relationship Between the Comprehensive Nutritional Index and the EORTC QLQ-H&N35 in Nasopharyngeal Carcinoma Patients Treated with Intensity-Modulated Radiation Therapy

Assessing malnutrition in patients with nasopharyngeal carcinoma: Diagnostic protocol for the development and validation of a new nutritional assessment tool

INTRODUCTION

There is currently no gold standard or specific nutritional assessment tool to assess malnutrition in patients with nasopharyngeal carcinoma (NPC). Our study aims to develop a new nutritional assessment tool for NPC patients.

METHODS AND ANALYSIS

NPC patients will be required to complete a risk factor questionnaire after obtaining their informed consent. The risk factor questionnaire will be used to collect potential risk factors for malnutrition. Univariate and multivariate logistic regression analyses will be used to identify risk factors for malnutrition. A new nutritional assessment tool will be developed based on risk factors. The new tool's performance will be assessed by calibration and discrimination. The bootstrapping will be used for internal validation of the new tool. In addition, external validation will be performed by recruiting NPC patients from another hospital.

DISCUSSION

If the new tool is validated to be effective, it will potentially save medical staff time in assessing malnutrition and improve their work efficiency. Additionally, it may reduce the incidence of malnutrition and its adverse consequences.

STRENGTHS AND LIMITATIONS OF THIS STUDY

The study will comprehensively analyze demographic data, disease status, physical examination, and blood sampling to identify risk factors for malnutrition. Furthermore, the new tool will be systematically evaluated, and validated to determine their effectiveness. However, the restricted geographical range may limit the generalizability of the results to other ethnicities. Additionally, the study does not analyze subjective indicators such as psychology.

ETHICS AND DISSEMINATION

The ethical approval was granted by the Ethical Committee of the First Affiliated Hospital of Guangxi Medical University (NO. 2022-KT-GUI WEI-005) and the Second Affiliated Hospital of Guangxi Medical University (NO. 2022-KY-0752).

Risk factors for malnutrition in patients with nasopharyngeal carcinoma

BACKGROUND

Malnutrition is a common complication in patients with nasopharyngeal carcinoma (NPC). However, there are few studies on risk factors for malnutrition in NPC patients. Our aims were to identify the risk factors for malnutrition in NPC patients.

METHODS

NPC patients were recruited in this cross-sectional study, and they were divided into well-nourished and malnourished groups according to the Global Leadership Initiative on Malnutrition (GLIM). Potential risk factors were initially screened using univariate analysis (p < 0.1), and the selected ones were analyzed by logistic regression analysis (p < 0.05) to identify the risk factors for malnutrition in NPC patients.

RESULTS

In total, 305 NPC patients meeting eligibility criteria were enrolled. Multivariate logistic regression analysis revealed that low body mass index (BMI) (OR = 0.596, 95% CI 0.520-0.683, p < 0.001), the high total radiation dose received (OR = 1.046, 95% CI 1.023-1.069, p < 0.001), appetite loss (OR = 2.839, 95% CI 1.269-6.353, p = 0.011), and low PA (OR = 0.993, 95% CI 0.988-0.998, p = 0.008) were risk factors for malnutrition in NPC patients.

CONCLUSIONS

The low BMI, the high total radiation dose received, appetite loss, and low prealbumin were risk factors for malnutrition in NPC patients.

A promising predictive biomarker combined EBV NDA with PNI for nasopharyngeal carcinoma in nonendemic area of China

In endemic areas, EBV DNA is used to guide diagnosis, detect recurrence and distant metastasis of NPC. Until now, the importance of EBV DNA in the prediction of NPC has received little attention in non-endemic regions. To explore the prognostic value of EBV DNA alone or in combination with PNI in NPC patients from a non-endemic area of China. In this retrospective study, 493 NPC patients were enrolled. Clinical pathologic data, pre-treatment plasma EBV DNA, and laboratory tests were all performed. A standard anticancer treatment was prescribed, and follow up data were collected. EBV DNA was found to be positively related to clinical stage (r = 0.357, P < 0.001), T stage (r = 0.193, P < 0.001), N stage (r = 0.281, P < 0.001), and M stage (r = 0.215, P < 0.001). The difference in EBV DNA loads between clinical stage, T, N and M stage was statistically significant (P < 0.001). In this study, the best cutoff value for EBV-DNA to distinguish the prognosis of NPC was 262.7 copies/ml. The 5-year OS of patients in the EBV-DNA ≤ 262.7 copies/ml group and EBV-DNA > 262.7 copies/ml group was 88% and 65.3%, respectively (P < 0.001). EBV-DNA and PNI were found to be independent prognostic factors for OS in multivariate analysis (P < 0.05). EBV-DNA was independent prognostic factors for PFS. In predicting NPC patients OS, the novel combination marker of EBV DNA and PNI outperformed TNM staging (AUC: 0.709 vs. 0.675). In addition, the difference between EBV + PNI and EBV + TNM was not statistically significant for OS or PFS (P > 0.05). This novel combination biomarker was a promising biomarker for predicting NPC survival and may one day guide treatment option.

The impact of multidisciplinary team nutrition management on nutritional and toxicity status in patients with nasopharyngeal carcinoma

Objective

To explore the impact of multidisciplinary team (MDT) nutrition management on the nutritional and toxicity status of patients with nasopharyngeal carcinoma undergoing chemoradiotherapy.

Methods

A total of 104 patients undergoing chemoradiotherapy for nasopharyngeal carcinoma admitted to our hospital from July 2018 to February 2021 were retrospectively enrolled, including who received conventional nutrition management (the routine group, n ​= ​52) and who received MDT nutrition management (the experimental group, n ​= ​52). Nutritional indicators (dietary intake, body mass index, serum albumin, serum prealbumin, hemoglobin, total lymphocyte count, serum transferrin [TRF]), the Nutrition Risk Screening 2002 (NRS2002) score and acute toxicity level were recorded before, during, and after chemoradiotherapy. Multiple regression analysis was performed to identify nutritional risk indicators.

Results

During and after chemoradiotherapy, the body mass index, albumin, prealbumin, hemoglobin, total lymphocyte count, TRF, dietary intake, number of patients with an NRS2002 score < 3, and acute toxicity score in the experimental group improved compared to those in the routine group (P ​< ​0.05). Concurrent chemotherapy, the NRS2002 score and a half-diet strategy were independent factors affecting the nutritional status of nasopharyngeal carcinoma patients who underwent chemoradiotherapy.

Conclusions

Active screening and evaluation of the nutritional status of patients with nasopharyngeal carcinoma during chemoradiotherapy as well as MDT nutrition management can be used to detect nutritional problems, thus improving quality of life and reducing related toxicity.

Mapping Health-Related Quality of Life, Anxiety, and Depression in Patients with Head and Neck Cancer Diagnosed with Malnutrition Defined by GLIM

Patients with cancer deal with problems related to physical, psychological, social, and emotional functions. The aim was to investigate malnutrition defined by the Global Leadership Initiative on Malnutrition (GLIM) criteria in relation to health-related quality of life, anxiety, and depression in patients with head and neck cancer. This was a prospective observational research study with 273 patients followed at the start of treatment, seven weeks, and one year. Data collection included nutritional status and support, and the questionnaires: European Organization for Research and Treatment of Cancer Head and neck cancer module (EORTC QLQ-H&N35) and the Hospital Anxiety and Depression Scale (HADS). Malnutrition was defined using the GLIM criteria. The study showed that patients with malnutrition had significantly greater deterioration in their health-related quality of life at seven weeks. On a group level, health-related quality of life was most severe at this time point and some scores still implied problems at one year. Significantly, more patients reported anxiety at the start of treatment whereas significantly more patients reported depression at seven weeks. Over the trajectory of care, the need for support often varies. Psychosocial support is imperative and at the end of treatment extra focus should be put on nutritional interventions and managing treatment-related symptoms to improve nutritional status and health-related quality of life. In the long-term, head and neck cancer survivors need help to find strategies to cope with the remaining sequel.

Construction of a comprehensive nutritional index and comparison of its prognostic performance with the PNI and NRI for survival in older patients with nasopharyngeal carcinoma: a retrospective study

OBJECTIVES

To explore the relationship between the Comprehensive Nutritional Index (CNI) and survival in older patients with nasopharyngeal carcinoma (NPC) and to compare the prognostic performance of three nutritional indicators (CNI, Prognostic Nutritional Index (PNI), and Nutritional Risk Index (NRI)) for overall survival (OS).

METHODS

This retrospective study involved 309 older NPC patients in Guangzhou (China) from November 2006 to November 2017. The CNI comprised five parameters: the body mass index (BMI), usual body weight percentage (UBW%), hemoglobin (Hb) level, albumin level, and total lymphocyte count (TLC). All single nutritional indicators were evaluated before and immediately after treatment. The principal component analysis (PCA) was used for calculation of the CNI by single nutritional indicators after treatment. The cutoff point for the CNI was evaluated and logistic regression used to explore the risk factors for the CNI. Univariable, multivariable Cox regression, and Kaplan-Meier methods were applied for OS and disease-free survival (DFS) analyses. Cox proportional hazards models were used to compare the prognostic value of the CNI, PNI, and NRI for OS.

RESULTS

All single nutritional indicators decreased significantly after treatment (P < 0.05). The CNI cutoff point for mortality was 0.027, and the logistic regression indicated more complex treatments or higher cancer stage for NPC was associated with a low CNI (HR = 0.179; 95% CI: 0.037-0.856; 0.545, 0.367-0.811, respectively). In multivariable Cox regression, the CNI remained an independent prognostic factor of OS and DFS (HR = 0.468, 95% CI: 0.263-0.832; 0.527, 0.284-0.977, respectively). Kaplan-Meier curves showed that a low CNI was associated with worse OS and DFS (P = 0.001 and 0.013, respectively). The prognostic predictive performance of the CNI was superior to that of the PNI or NRI.

CONCLUSIONS

The CNI can be recommended as an appropriate indicator reflecting the integrated nutritional status of older NPC patients. A low CNI predicted a poor survival outcome and the prognostic performance of CNI was superior to PNI or NRI.

Weight Change Trajectory in Patients With Locally Advanced Nasopharyngeal Carcinoma During the Peri-Radiation Therapy Period

OBJECTIVES

To analyze the weight change trajectory in patients with locally advanced nasopharyngeal carcinoma (LANPC) before, during, and after radiation therapy for a time span of 40 weeks.

SAMPLE & SETTING

147 patients from a university-affiliated medical center in China were included.

METHODS & VARIABLES

Body weight was measured weekly during intensive treatment and biweekly after radiation therapy.

RESULTS

All 147 patients experienced critical weight loss during the peri-radiation therapy period. Overall, body weight remained basically unchanged during induction chemotherapy, followed by a sharp and severe decrease during radiation therapy. At 20 weeks after radiation therapy, body weight had increased only slightly from the lowest point.

IMPLICATIONS FOR NURSING

A time-tailored intervention based on the weight change trajectory is necessary for patients with LANPC. According to the weight change trajectory, relevant interventions for maintaining body weight should be initiated as early as the second week of radiation therapy and no later than the fourth week of radiation therapy, and these interventions should continue for at least four weeks after radiation therapy.

The prognostic role of prognostic nutritional index in nasopharyngeal carcinoma: A systematic review and meta-analysis

PURPOSE

The prognostic utility of the prognostic nutritional index (PNI) in nasopharyngeal carcinoma (NPC) has never been systematically reviewed. Therefore, we performed this meta-analysis.

METHODS

We performed comprehensive research via Embase, PubMed, Web of Science and the Cochrane Library. The pooled hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were applied to explore the relationship between PNI and overall survival (OS), progression-free survival (PFS), locoregional failure-free survival (LRFFS), distant metastasis-free survival (DMFS) and clinical features. Both univariate analysis (UVA) and multivariate analysis (MVA) were used.

RESULTS

A total of 8 eligible studies including 3631 patients were ultimately enrolled. A low PNI level was significantly associated with a shorter OS [(HR 2.06, P < 0.00001; UVA) and (HR 1.78, P < 0.00001; MVA)], PFS [(HR 2.27, P = 0.006; UVA) and (HR 1.45, P = 0.0003; MVA)] and DMFS [(HR 2.06, P < 0.00001; UVA) and (HR 2.04, P < 0.00001; MVA)]. However, only one study reported the LRFFS of NPC patients, and there was no significant difference [HR 1.68, P = 0.26]. Furthermore, female patients, higher tumor stage, a lower alanine transaminase (ALT) level and a lower white blood cell (WBC) level were associated with a lower PNI level.

CONCLUSION

Our meta-analysis indicated that NPC patients with a low PNI level had worse OS, PFS and DMFS, and a low PNI level was associated with female patients, higher tumor stage, a lower ALT level and a lower WBC level. These findings indicate that PNI is a promising prognostic biomarker.

Health-related quality of life became worse in short-term during treatment in head and neck cancer patients: a prospective study

BACKGROUND

Quality of life (QoL) is influenced in head and neck cancer (HNC) patients by a set of factors related to diagnosis, treatment and tumor impacts. The aim of this study was to evaluate the Quality of Life (QoL) changes in Head and Neck cancer (HNC) patients during treatment (radiotherapy and/or chemoradiotherapy).

METHODS

QoL was evaluated prospectively in 63 HNC patients during radiotherapy and/or chemoradiotherapy at three moments: before or at beginning (T0), in the middle (T1 ~ four weeks) and immediately at the end (T2 ~ eight weeks) of treatment. The differences between the scores at different time points was verified using Friedman's non-parametric test. Negative changes between time points were evaluated, with differences (delta) of ±10 points being considered to be clinically significant.

RESULTS

The total mean age was 59.1 ± 9.5y, and 82.5% were male. The oral cavity and larynx were more frequent tumors. The functional score for 'role' was decreased at time points T1 and T2 as compared to T0, while an improvement in scores was observed for cognitive function. Several physical symptoms also worsened over time, such as: fatigue, nausea and vomiting, dry mouth and sticky saliva, swallowing and skin symptoms, senses and teeth problems. A high frequency of altered and clinically meaningful values were observed for most of domains, ranging from 6 to 74%.

CONCLUSIONS

The QoL became worse at approximately one month after treatment beginning in HNC patients, and this remained until the end of therapy. Protocols directing to early nutritional counseling and management of symptoms of nutritional impact are important to improve clinical outcomes. This is part of preventive actions aiming to make the exhausting treatment process less traumatic and easier to complete.

Prognostic value of nutritional impairment on treatment-related toxicity and survival in patients with nasopharyngeal carcinoma taking normal nutrition before radiotherapy

BACKGROUND

To investigate nutritional impairment during intensity-modulated radiotherapy (IMRT) in patients with nasopharyngeal carcinoma (NPC) taking normal nutrition before IMRT and its effect on treatment-related toxicities (TRTs) and survival.

METHODS

Modified nutrition index (m-NI) of 187 patients with NPC, comprised eight indicators (body mass index, circumference of upper arm muscles, total lymphocyte count, red blood cell count, levels of albumin, pre-albumin, transferrin, and hemoglobin), were evaluated before/after IMRT. Patient characteristics, m-NI, and the follow-up data for survival and TRTs were analyzed.

RESULTS

The m-NI scores of patients with NPC decreased significantly after IMRT. Severe nutritional impairment (SNI; decrease in m-NI score ≥50%) was an independent prognostic factor for overall survival (OS) and an independent risk factor for grade ≥2 oral mucositis. Classification T4 disease and smoking were SNI risk factors.

CONCLUSIONS

SNI during IMRT is a risk factor for oral mucositis and a prognostic factor for worse OS in patients with NPC.

Systematic nutrition management for locally advanced nasopharyngeal carcinoma patients undergoing radiotherapy

Objective

To evaluate the impact of systematic nutrition management (SNM) on nutritional status, treatment-related toxicity, quality of life (QoL), response rates, and survival in patients with locally advanced nasopharyngeal carcinoma (LA-NPC) treated by radiotherapy (RT).

Methods

In this retrospective study, 56 patients with LA-NPC were selected as nutrition management group (NG) for SNM during RT till 1 month later. Another 56 patients with LA-NPC receiving RT without SNM as control group (CG) were identified from the hospital database and matched pairs with NG patients according to age, gender, stage, and body mass index (BMI) prior to RT.

Results

At 1 month after RT, the percentage of malnourished patients with BMI <18.5 kg/m² was statistically significant reduced in NG as compared to the CG group (35.7% vs 58.9%, P=0.014). Nutritional indexes of body weight, hemoglobin, prealbumin, and lymphocyte in the NG were statistically significant higher than those in the CG group (P<0.05). NG patients had statistically significant less grade 3–4 oral mucositis during RT compared with the CG group (32.1% vs 51.8%, P=0.035). Furthermore, at 1 month after RT, an improved QoL was observed in NG patients with respect to physical, role and social functions, symptom scales of fatigue and pain, and the global health status as compared to the CG group (P<0.05). With a median follow-up of 24.8 months, there were no statistical differences between NG and CG (P>0.05) for the 2-year progression-free survival and overall survival (84.2% versus 79.5% and 94.7% versus 92.3%, respectively.).

Conclusion

SNM for LA-NPC patients treated by RT resulted in better nutritional status, reduced treatment-related toxicity and improved QoL.

Construction of a comprehensive nutritional index and its correlation with quality of life and survival in patients with nasopharyngeal carcinoma undergoing IMRT: A prospective study

OBJECTIVES

The aim of this study was to investigate the relationship between a comprehensive nutritional index (CNI) and QoL in patients with NPC who undergo IMRT and to explore the relationship between CNI and survival.

METHODS

359 patients with newly diagnosed NPC were enrolled. QoL was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 and Quality of Life Questionnaire Head and Neck Cancer Module at three time points: before, immediately after, and 3 months after IMRT. The CNI comprised five values including body mass index, usual body weight percentage, hemoglobin, albumin, and total lymphocyte count, and was evaluated before and immediately after IMRT. The correlation between the CNI and QoL and the effect of CNI on prognosis were analysed.

RESULTS

QoL and CNI scores decreased remarkably after IMRT (P < 0.05). The CNI was quite low in patients with III-IV clinical tumor stage and those undergoing induction chemotherapy plus concurrent chemotherapy. After IMRT, lower CNI score correlated worse QoL (P < 0.05). The Kaplan-Meier curve indicated that patients with lower CNI had significantly poorer survival outcomes (P = 0.02). In multivariate analysis, CNI remained an independent prognostic factor of overall survival (P = 0.046).

CONCLUSIONS

CNI can be recommended as an appropriate indicator reflecting the integrated nutrition status of NPC patients. Low CNI was associated with poor QoL and predicted a poor survival outcome. More interventions should be taken to improve the nutrition status of NPC patients to improve QoL and enhance survival outcomes.

Home enteral nutrition may prevent myelosuppression of patients with nasopharyngeal carcinoma treated by concurrent chemoradiotherapy

BACKGROUND

The aim of this study is to assess the effect of home enteral nutrition (HEN) on the myelosuppression of patients with nasopharyngeal cancer (NPC) during the course of concurrent chemoradiotherapy (CCRT).

METHODS

A total of 18 outpatients with NPC administered oral nutritional supplementation intervention at home during the course of CCRT were designated as the HEN group, whereas 36 patients with NPC who had previously completed CCRT were retrospectively included as the control group. Patient Generated Subjective Global Assessment, body mass index (BMI), and blood test were evaluated prior to CCRT. During the course of CCRT, blood test was assessed every 2 weeks.

RESULTS

In male patients, hemoglobin (HB) and red blood cell were decreased (P < .05) in both HEN and control group after CCRT, whereas white blood cell (WBC) started to decrease since week 2 of CCRT in the control group but maintained in the HEN group which was significantly higher than the control (5.05 ± 1.29 vs 3.77 ± 1.5, P < .05). In female patients, HB and WBC were reduced in control group during CCRT, whereas these indicators also maintained in the HEN group. Surprisingly, all patients with lower BMI (<24 kg/m² ) had a significant increase in platelet (PLT) after CCRT (200.78 ± 58.03 vs 253.00 ± 69.82, P < .05), while had steady HB and WBC values in the HEN group. At the end of CCRT, WBC and PLT of the HEN group were both higher than those in the control group (5.21 ± 1.07 vs 3.37 ± 1.52), (253.00 ± 69.82 vs 165.57 ± 59.56) (P < .05 for both). Our findings suggest that HEN is effective in preventing myelosuppression during CCRT for patients with NPC.

CONCLUSION

Our findings suggest that HEN is effective in preventing myelosuppression during CCRT for patients with NPC.
