RESUMEN

Background: Several factors can affect overall survival of head and neck cancer (HNC) patients, including characteristics of the cancer disease and response to treatments. However, patients' nutritional status and the effectiveness of medical nutrition therapy (MNT) can also impact overall survival. The primary goal of our research was to collect real-life data on the use of MNT in HNC patients and to specifically investigate the correlation between survival and the duration of uninterrupted (persistent) nutrition. Method: The data of this retrospective, analytical, cohort study was collected from electronic healthcare records from the Hungarian National Health Insurance Fund Management. Overall, 38,675 HNC patients' data of the period between 2012 and 2021 was used. We applied multi-step exclusions to identify patient groups accurately and to avoid biasing factors. Statistical analysis was done by the Kaplan-Meier method, log-rank test, and Cox regression analysis. Results: Throughout the investigated period 16,871 (64%) patients received MNT therapy out of 26,253 newly diagnosed patients (≥18 years). In terms of the persistence of MNT, we divided the patients into three groups (1-3; 4-6; ≥7-month duration of MNT). When comparing these groups, we found that patients receiving long-term (≥7 months) MNT had a significantly longer overall survival (p < 0.0001) than those who received MNT for a shorter duration, both in locally advanced and recurrent/metastatic cases. Conclusion: The main outcome of the study is that there is a positive correlation between the persistence of MNT and the overall survival in HNC patients when nutritional intervention lasts several months. It highlights the responsibility of the specialists during the patient journey to use MNT early and to continue its use for as long as it is beneficial to the patients.

RESUMEN

OBJECTIVES: Concurrent chemoradiation to treat head and neck cancer (HNC) may result in debilitating toxicities. Targeted exercise such as yoga therapy may buffer against treatment-related sequelae; thus, this pilot RCT examined the feasibility and preliminary efficacy of a yoga intervention. Because family caregivers report low caregiving efficacy and elevated levels of distress, we included them in this trial as active study participants. METHODS: HNC patients and their caregivers were randomized to a 15-session dyadic yoga program or a waitlist control (WLC) group. Prior to randomization, patients completed standard symptom (MDASI-HN) and patients and caregivers completed quality of life (SF-36) assessments. The 15-session program was delivered parallel to patients' treatment schedules. Participants were re-assessed at patients' last day of chemoradiation and again 30 days later. Patients' emergency department visits, unplanned hospital admissions and gastric feeding tube placements were recorded over the treatment course and up to 30 days later. RESULTS: With a consent rate of 76%, 37 dyads were randomized. Participants in the yoga group completed a mean of 12.5 sessions and rated the program as "beneficial." Patients in the yoga group had clinically significantly less symptom interference and HNC symptom severity and better QOL than those in the WLC group. They were also less likely to have a hospital admission (OR = 3.00), emergency department visit (OR = 2.14), and/or a feeding tube placement (OR = 1.78). CONCLUSION: Yoga therapy appears to be a feasible, acceptable, and possibly efficacious behavioral supportive care strategy for HNC patients undergoing chemoradiation. A larger efficacy trial is warranted.

RESUMEN

PURPOSE OF REVIEW: The purpose of this review is to summarize current evidence regarding management of head and neck lymphoedema (HNL) to improve dysphagia outcomes following head and neck cancer (HNC) treatment. This review aims to support complete decongestive therapy (CDT) comprising compression, manual lymphatic drainage (MLD), exercises and skincare as an adjunct of dysphagia rehabilitation. RECENT FINDINGS: Research in the limbs supports the use of CDT to improve lymphoedema outcomes. Emerging evidence supports the use of CDT for the head and neck, though, there is no consensus on optimal treatment required to improve dysphagia outcomes. Current evidence is limited due to a paucity of randomized controlled trials, case series or cohort studies with small participant numbers, and a lack of functional and instrumental dysphagia outcome measures. This provides a foundation to design and test an individually tailored programme of HNL intervention to evaluate swallowing outcomes post CDT. SUMMARY: As the incidence of HNC is increasing with HPV, with patients living for longer with late effects of HNC treatment, it is vital to understand how the presence of HNL impacts on the swallow, and if functional dysphagia outcomes improve following treatment of HNL. Prospective, longitudinal research with objective and functional outcome measures are required to help determine optimal management of HNL and its impact on the swallow.

RESUMEN

PURPOSE: Malnutrition affects up to 80% of patients with head and neck cancer (HNC) and is associated with higher burden of disease, poorer treatment outcomes, and greater mortality. The Eating As Treatment (EAT) intervention is a behavioral intervention previously demonstrated to be effective in improving nutritional status, depression, and quality of life in patients with HNC. This article examines the effects of the EAT intervention on 5-year mortality among participants. METHODS AND MATERIALS: A multicenter, stepped-wedge, randomized controlled trial was conducted in 5 Australian hospitals. Dietitians were trained to deliver EAT, a combination of motivational interviewing and cognitive behavior therapy strategies, to patients with HNC receiving radiation therapy. Secondary analyses of survival benefit on an intention-to-treat basis were performed. Differences in proportions of 5-year all-cause mortality between the control and EAT intervention arms were analyzed using multivariable logistic regression, and 5-year survival rates were analyzed using Cox proportional hazards regression. Analyses controlled for temporal effects (study duration), hospital site (clustering), and baseline nutritional status differences. RESULTS: Overall, there were 64 deaths in the 5 years after enrollment, 36 (24%) among those assigned to the control condition and 28 (18%) among those assigned to EAT. Logistic regression showed statistically significant reduced odds in favor of EAT (odds ratio, 0.33; 95% CI, 0.11-0.96), with an absolute risk reduction of 17% (95% CI, 0.01-0.33) and a relative risk reduction of 55% (95% CI, 0.22-0.92), resulting in a number needed to treat of 6 (95% CI, 4-13). Survival analysis revealed that risk of death was significantly reduced by the EAT intervention (hazard ratio, 0.39; 0.16-0.96). CONCLUSIONS: Participation in EAT provided a statistically and clinically meaningful survival benefit, likely via improved nutrition during radiation therapy. This survival benefit strengthens the finding of the main trial, showing that a behavioral intervention focused on nutrition could improve HNC outcomes. Replication studies using stepped-wedge designs for implementation into clinical practice may be warranted.

RESUMEN

The research was conducted to examine the correlation between nutritional status and wound healing in individuals who were receiving treatment for head and neck cancer. Specifically, this study sought to identify crucial nutritional factors that influenced both the recovery process and efficacy of the treatment. From February 2022 to September 2023, this cross-sectional study was undertaken involving 300 patients diagnosed with head and neck cancer who were treated at Tianjin Medical University Cancer Institute and Hospital, Tianjin, China. In order to evaluate nutritional status, body mass index (BMI), serum protein levels and dietary intake records were utilized. The assessment of wound healing was conducted using established oncological wound healing scales, photographic documentation and clinical examinations. After treatment, we observed a noteworthy reduction in both BMI (p < 0.05) and serum albumin levels (p < 0.05). There was slightly increased prevalence of head and neck cancer among males (61.0%, p < 0.05). Over the course of 6 months, significant enhancement in wound healing scores was noted, exhibiting overall improvement of 86% in the healing process. An inverse correlation was identified between nutritional status and wound healing efficacy through multivariate analysis. A logistic regression analysis revealed a significant positive correlation (p < 0.05) between elevated levels of serum protein and total lymphocytes and enhanced wound healing. Conversely, negative correlation (p < 0.05) was observed between larger wound size at baseline and healing. The research findings indicated noteworthy association between malnutrition and impaired wound repair among individuals diagnosed with head and neck cancer. The results underscored the significance of integrating nutritional interventions into therapeutic protocol in order to enhance clinical results. This research study provided significant contributions to the knowledge of intricate nature of head and neck cancer management by advocating for multidisciplinary approach that incorporates nutrition as the critical element of patient care and highlighted the importance of ongoing surveillance and customized dietary approaches in order to optimize wound healing and treatment efficacy.

RESUMEN

PURPOSE: Recent breakthroughs in natural language processing and machine learning, exemplified by ChatGPT, have spurred a paradigm shift in healthcare. Released by OpenAI in November 2022, ChatGPT rapidly gained global attention. Trained on massive text datasets, this large language model holds immense potential to revolutionize healthcare. However, existing literature often overlooks the need for rigorous validation and real-world applicability. METHODS: This head-to-head comparative study assesses ChatGPT's capabilities in providing therapeutic recommendations for head and neck cancers. Simulating every NCCN Guidelines scenarios. ChatGPT is queried on primary treatments, adjuvant treatment, and follow-up, with responses compared to the NCCN Guidelines. Performance metrics, including sensitivity, specificity, and F1 score, are employed for assessment. RESULTS: The study includes 68 hypothetical cases and 204 clinical scenarios. ChatGPT exhibits promising capabilities in addressing NCCN-related queries, achieving high sensitivity and overall accuracy across primary treatment, adjuvant treatment, and follow-up. The study's metrics showcase robustness in providing relevant suggestions. However, a few inaccuracies are noted, especially in primary treatment scenarios. CONCLUSION: Our study highlights the proficiency of ChatGPT in providing treatment suggestions. The model's alignment with the NCCN Guidelines sets the stage for a nuanced exploration of AI's evolving role in oncological decision support. However, challenges related to the interpretability of AI in clinical decision-making and the importance of clinicians understanding the underlying principles of AI models remain unexplored. As AI continues to advance, collaborative efforts between models and medical experts are deemed essential for unlocking new frontiers in personalized cancer care.

RESUMEN

CONTEXT: In our institution, patients with upper aero-digestive tract cancer receive adapted physical activity (APA) awareness training as part of their holistic oncology care program. The main aim of this study was to show that raising awareness of APA helped to increase self-reported PA levels, as assessed by questionnaire. METHOD: This retrospective study included 67 patients with localized Head and Neck cancer. The intervention consisted of an APA teacher; a face-to-face consultation before the start of oncological treatment, four monthly telephone interventions in the three months following the end of treatment. The pre-post evaluation focused on self-reported APA practices before and three months after the end of oncology treatment. RESULTS: APA awareness training significantly increased average total PA, average moderate PA intensity, average weekly walking frequency, average walking intensity, and significantly reduced daily sitting time. The search for correlations between body composition or type of treatments and changes in PA levels showed no significant results. CONCLUSION: This study showed that a basic APA awareness training integrated into a holistic oncology care program could increase patients' self-reported PA levels. The next step will be to verify the objectivity of the increase in self-reported PA, and then to assess its effect on quality of life and survival.

RESUMEN

Numerous studies have examined the effectiveness of photobiomodulation therapy (PBMT) in reducing chemoradiotherapy (CRT)-induced oral mucositis (OM) in patients with head and neck cancer (HNC). Despite this, there is an urgent need to update the meta-analyses on this topic. This meta-analysis aims to explore the impact of PBMT on CRT-induced OM in these patients. We conducted a systematic search in PubMed, Embase, Cochrane, LILACS, and Web of Science from January 2000 to October 2023. This search focused on randomized controlled trials (RCTs) that assessed the effects of PBMT on CRT-induced OM. The study included a total of 14 RCTs encompassing 869 patients with HNC. The incidence of OM in the PBMT group was significantly lower from the second week onwards compared to the control group (RR = 0.49, CI = 0.25-0.97, I2 = 71%, p = 0.04), and this was present until the seventh week (RR = 0.77, CI = 0.61-0.99, I2 = 89%, p = 0.04). Furthermore, the occurrence of severe mucositis in the PBMT group decreased from the third week (RR = 0.51, CI = 0.29-0.90, I2 = 12%, p = 0.02) until the conclusion of the intervention (RR = 0.45, CI = 0.24-0.85, I2 = 80%, p = 0.01). Additionally, PBMT showed beneficial effects in alleviating OM-related pain (WMD = -1.09, 95% CI = -1.38 to -0.880, I2 = 13%, p < 0.00001). The use of He-Ne or InGaAlP lasers with a power range of 10-25 mW demonstrated the most favorable outcomes in preventing and treating OM. PBMT has shown considerable efficacy in reducing the incidence, severity, and pain associated with OM in patients with HNC. Future studies are encouraged to further investigate the most effective parameters for PBMT in the management of OM.

RESUMEN

PURPOSE: Health literacy is a current Public Health priority in Portugal. The participation of well-informed patients in their care and shared decision making are essential, especially in chronic aggressive and debilitating pathologies such as recurrent or metastatic (R/M) Head and Neck Squamous Cell Carcinoma (HNSCC). AIMS: This study aimed to characterize R/M HNSCC patients' and caregivers' information needs identified by healthcare professionals (HCPs). METHODS: Two online Focus Groups, one with only medical doctors and the other with other HCPs involved in the treatment of R/M HNSCC patients, were conducted, using a modified Metaplan, Lean or adapted PDCA methodology. The discussions were audio recorded in full and content analysis was performed using ATLAS.ti qualitative data analysis software. RESULTS: Topics addressed were diagnosis, treatment, quality of life, and global evaluation. In general, all experts agreed that only essential information should be cautiously given, according to patients' and caregivers' wishes. It was consensual that patients are given the necessary information to adhere to treatment. Two main barriers were identified: one barrier was associated with verbal communication due to the lack of health literacy of these patients, and the other barrier regarded healthcare access. It was also considered important to remind patients of the daily and social activities that they could and should maintain, as well as providing sufficient social resources and problem-solving training to caregivers. CONCLUSIONS: This qualitative study highlights the complexity of R/M HNSCC patients' care. Immediate availability of psychologists and psychiatrists should be implemented in all centers that treat HNSCC patients. The differences found between the physicians' Focus Group and other HCPs' Focus Group in some of the addressed topics emphasize the importance of a multidisciplinary and holistic approach, in a biomedical model integrated with a biopsychosocial model.

RESUMEN

OBJECTIVES: The utility of intensive posttreatment surveillance of head and neck squamous cell carcinoma (HNSCC) has been debated. The objective is to investigate adherence to the National Comprehensive Cancer Network (NCCN) posttreatment follow-up guidelines and assess the association with recurrence and survival. METHODS: A total of 452 patients diagnosed with HNSCC at an academic medical center in a socioeconomically disadvantaged, urban setting were categorized by adherence to NCCN follow-up guidelines. Survival analyses were conducted to study the association between adherence and the 5-year overall survival and disease-specific survival in the entire cohort and subset of patients with documented recurrence. RESULTS: We found that 23.5% of patients were adherent to NCCN follow-up guidelines in the first year after treatment, and 15.9% were adherent over 5 years. Adherence in the first year was significantly associated with 5-year overall survival (HR 0.634; 95% CI 0.443-0.906; p = 0.0124) and disease-specific survival (HR 0.556; 95% CI 0.312-0.992; p = 0.0470), but consistent adherence over 5 years did not show a significant association. Among the 21.7% of the cohort with recurrence, adherence was not associated with early-stage recurrence (AJCC stage I/II). In this subset, first year adherence was associated with improved disease-specific but not overall survival, and adherence over 5 years was not associated with survival. CONCLUSION: Adherence to NCCN follow-up guidelines in the first year after treatment was associated with a better chance of 5-year overall and disease-specific survival, but this significant association was not observed among those who demonstrated consistent adherence over 5 years. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:708-716, 2024.

RESUMEN

OBJECTIVE: To identify socioeconomic factors influencing the presentation and outcomes of cutaneous head and neck squamous cell carcinoma (cHNSCC). STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary academic medical center with comprehensive cancer center. METHODS: Patients treated for cHNSCC at a single institution between 2008 and 2022 were included. Demographic, socioeconomic data and disease characteristics were obtained from medical record abstraction. Outcome measures included tumor stage, number of distinct primaries, recurrence, and disease-related death. χ2 and Mann-Whitney tests were implemented to evaluate clinicopathologic distributions across disease stages. Survival analyses were performed using Cox regression and Kaplan-Meier analysis. RESULTS: A total of 346 patients met the inclusion criteria. The median age at presentation and length of follow-up was 70.8 and 3.1 years, respectively. The majority of the cohort was white, male, and English-speaking. 13.3% of patients were underinsured and 27.5% were immunosuppressed. Patients who presented with advanced disease were more likely to be underinsured (21.7% vs 9.6%, P = .006) and have a history of homelessness (8.5% vs 2.1%, P = .014). Immunosuppressed patients were more likely to be underinsured (P = .009). Insurance status (1.97 [1.06-3.66], P = .032) and immune status (2.35 [1.30-4.26], P = .005) were independently associated with worse recurrence-free survival. CONCLUSION: Socioeconomic factors that influence access to care, such as insurance status, are associated with cHNSCC disease stage and disease recurrence. These factors may impose barriers that delay diagnosis and treatment. This may result in worse disease-related outcomes and greater treatment-associated morbidity for certain patients.

RESUMEN

PURPOSE OF REVIEW: In 2017, the American Joint Committee on Cancer (AJCC) introduced the inclusion of extracapsular nodal extension (ENE) into the N staging of nonviral head and neck squamous cell carcinoma (HNSCC), while retaining the traditional N classification based on the number and sizes of metastatic nodes. The extent of ENE was further defined as microscopic ENE (ENEmi) and major ENE (ENEma) based on extent of disease beyond the nodal capsule (≤ or > 2 mm). This article reviews the evidence and progress made since these changes were introduced. RECENT FINDINGS: The 'gold standard' for evaluation ENE is histopathologic examination, the current preferred primary treatment of patients with HNSCC is by radiation-based therapy ±â€Šchemotherapy or biotherapy. The current pretreatment staging is by imaging, which needs improved reliability of radiologic rENE assessment with reporting needs to consider both sensitivity and specificity (currently computed tomography images have high-specificity but low-sensitivity). Adjuvant chemotherapy is indicated for patients with ENEma to enhance disease control, whereas for patients with ENEmi, there is a need to assess the benefit of adjuvant chemotherapy. Evidence that the presence of pENE in HPV-positive oropharyngeal carcinoma is an independent prognostic factor and should be considered for inclusion in future AJCC editions has recently emerged. SUMMARY: There remains a paucity of data on the reliability of imaging in the staging of rENE, more so the for the accurate assessment of ENEmi. Optimistic early results from use of artificial intelligence/deep learning demonstrate progress and may pave the way for better capabilities in tumor staging, treatment outcome prediction, resulting in improved survival outcomes.

RESUMEN

Several molecular-targeted imaging and therapeutic agents are in clinical trials for image-guided surgery and photoimmunotherapy (PIT) for head and neck cancers. In this context, we have previously reported the development, characterization, and specificity of a dual-function antibody conjugate (DFAC) for multimodal imaging and photoimmunotherapy (PIT) of EGFR-overexpressing cancer cells. The DFAC reported previously and used in the present study comprises an EGFR-targeted antibody, cetuximab, conjugated to benzoporphyrin derivative (BPD) for fluorescence imaging and PIT and a Si-centered naphthalocyanine dye for photoacoustic imaging. We report here the evaluation and performance of DFAC in detecting microscopic cancer spheroids by fluorescence and photoacoustic imaging along with their treatment by PIT. We demonstrate that while fluorescence imaging can detect spheroids with volumes greater than 0.049 mm3, photoacoustic imaging-based detection was possible even for the smallest spheroids (0.01 mm3) developed in the study. When subjected to PIT, the spheroids showed a dose-dependent response, with smaller spheroids (0.01 and 0.018 mm3) showing a complete response with no recurrence when treated with 100 J/cm2. Together our results demonstrate the complementary imaging and treatment capacity of DFAC. This potentially enables fluorescence imaging to assess the presence of tumor on a macroscopic scale, followed by photoacoustic imaging for delineating tumor margins guiding surgical resection and elimination of any residual microscopic disease by PIT, in a single intraoperative setting.

RESUMEN

PURPOSE: This study aimed to investigate whether malnutrition or nutrition impact symptoms (NIS) affect the possibility of returning to work after treatment for head and neck cancer. METHODS: Patients of working age with head and neck cancer were followed up from treatment initiation to 3 months (n = 238), 1 year (n = 182), and 2 years (n = 130) after treatment completion. The observed decrease in the number of patients over time was due to retirement, lack of follow-up, or death. Returning to work was dichotomised as yes or no. Malnutrition was diagnosed 7 weeks after treatment initiation using the Global Leadership Initiative on Malnutrition (GLIM) criteria. This time-point corresponds to the end of chemoradiotherapy or radiotherapy (with or without prior surgery), except for patients who underwent exclusive surgery. NIS were scored on a Likert scale (1-5) at each follow-up using the Head and Neck Patient Symptom Checklist© (HNSC©). Nonparametric tests were used to analyse the ability of patients with/without malnutrition and high/low NIS scores to return to work. RESULTS: At 3 months, 1 year, and 2 years after treatment completion, 135/238 (56.7%), 49/182 (26.9%), and 23/130 (17.7%) patients had not returned to work. Patients with malnutrition at 7 weeks after treatment initiation were more likely to not return to work at 3 months than those without malnutrition, 70.5% compared to 47.1% (p < 0.001). At all three follow-up time-points, patients reporting high scores for a number of NIS had more often not returned to work, with this pattern being most distinct at 2 years. CONCLUSION: Malnutrition according to the GLIM criteria at 7 weeks after treatment initiation and NIS assessed by the HNSC© at subsequent follow-ups were predictors of the return-to-work process after treatment for up to 2 years. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT03343236 (date of registration 17/11/2017).

RESUMEN

At the 45th Congress of ESPEN (The European Society for Clinical Nutrition and Metabolism), we presented for the first time the initial results of our 2023 oncology research, in which we revealed positive correlations between the persistence of medical nutrition therapy and overall survival, in head and neck cancer patients. Patients who received longterm nutrition therapy (≥7 months) had a significantly longer survival (p<0.0001) than those who received only short-term nutrition therapy intervention, i.e., for 1-3 months. The aim, methodology and results of the Hungarian research aroused the interest of the congress participants; therefore, we also publish it in Hungarian in the form of a short notice.

RESUMEN

The present pilot study aims to investigate the diagnostic and prognostic efficacy of serum HSP90 beta in Head and Neck Squamous Cell Carcinoma (HNSCC) patients subjected to localized hyperthermia therapy (HT). Serum levels of HSP90 beta were measured by ELISA and its diagnostic and prognostic efficacy was determined by receiver operating characteristic curve (ROC) analysis. HNSCC patients showed significantly (P<0.05) higher serum levels of HSP90 beta (65.6±13.08 ng/ml) compared to Healthy Controls (HC: 23.5±3.8 ng/ml). No significant difference was observed in serum HSP90 beta levels between complete responders (CR) and non-responders (NR) in the chemo-radiation therapy (CRT) cohort. However, in CRT+HT cohort, CR showed significantly (P = 0.02) lower serum HSP90 beta levels at 24 h after HT (25.6±9.04 ng/ml) compared to NR (130.5±34.2 ng/ml). Youden's index values between HNSCC versus HC, CR versus NR (CRT) and CR versus NR (CRT+HT) were found to be 0.47, 0.45 and 0.80, respectively. Thus, alterations in the serum HSP90 beta after HT suggest its potential in prognosis of HT response in HNSCC patients. Elevated levels of HSP90 beta may serve as a promising diagnostic serum bio-marker for HNSCC. However, further validation in larger patient samples is needed for clinical translation of HSP90 beta as diagnostic and prognostic biomarker.

RESUMEN

OBJECTIVES: Nutritional intervention, including nutritional counseling (NC), plays a significant role in the comprehensive management of patients with head and neck cancer (HNC). The aim of this study was to investigate the effects of NC combined with oral nutritional supplements during radical treatment on weight loss and survival outcomes in patients with HNC. METHODS: The study included 310 patients who received radical treatment for HNC. Among these patients, 119 underwent NC along with oral nutritional supplements (NCONS); 191 were supported with oral nutritional supplements only (ONS). The study aimed to investigate the effects of sex, disease stage, treatment modality, and tumor site on weight loss. Additionally, the Kaplan-Meier method assessed the influence of NC on overall survival and disease-free survival. RESULTS: The present study suggested that the NC independently prevented weight loss, regardless of sex and disease stage (female: -1.6%, P = 0.001; male: -2.3 %, P = 0.003; T stage (0-2): -1.7%, P = 0.008; T stage (3-4): -2.7%, P = 0.003; N stage (0-1): 2.5%, P = 0,027; N stage (3-4): 2.9%, P < 0.001). The protective effect was most significant in patients with oral cancer and oropharyngeal cancer and in patients treated with chemotherapy (oral: -1.7%, P = 0.03; oropharynx: -3.3%, P < 0.001; radiochemotherapy: -3%, P = 0.028; induction chemotherapy preceded radiochemotherapy: -6%, P < 0.001). Furthermore, the 3-year overall survival rates were 93.4% and 85.4% in the NC along with oral nutritional supplements (NCONS) and oral nutritional supplement (ONS) groups, respectively (P = 0.031). CONCLUSIONS: Patients with HNC who received NC during radical treatment experienced reduced weight loss. This effect was particularly pronounced in patients with oral cavity or oropharyngeal cancer and those undergoing chemotherapy. Additionally, NC was associated with improved overall survival in this patient cohort. Nevertheless, further studies are required to validate and support these findings.

RESUMEN

BACKGROUND: Rural post-treatment head and neck cancer (HNC) survivors experience high rates of cancer-related distress and may experience unique symptom clusters. Oncology nurses can benefit from a better understanding of the symptom clusters that HNC survivors experience. OBJECTIVES: The purpose of this secondary data analysis was to identify symptom clusters of cancer-related distress in rural HNC survivors. METHODS: Secondary data analysis was conducted with survey data collected from rural HNC survivors (N = 20). Distress symptoms were measured using the National Comprehensive Cancer Network Distress Thermometer and Problem List, amended for a population with HNC. Symptom clusters were defined as two or more co-occurring symptoms and evaluated based on participant-reported severity using exploratory factor analysis. Resultant clusters were assessed for theoretical and clinical appropriateness. FINDINGS: Preliminary analysis suggests rural HNC survivors experience eight symptom clusters. As a first step, the results of this study can help nurses to identify symptom clusters in rural HNC survivors.
