RESUMEN
BACKGROUND: Immune-related characteristics can serve as reliable prognostic biomarkers in various cancers. Herein, we aimed to construct an individualized immune prognostic signature in nasopharyngeal carcinoma (NPC). METHODS: This study retrospectively included 455 NPC samples and 39 normal healthy nasopharyngeal tissue specimens. Samples from Gene Expression Omnibus (GEO) were obtained as discovery cohort to screen candidate prognostic immune-related gene pairs based on relative expression ordering of the genes. Quantitative real-time reverse transcription-PCR was used to detect the selected genes to construct an immune-related gene pair signature in training cohort, which comprised 118 clinical samples, and was then validated in validation cohort 1, comprising 92 clinical samples, and validation cohort 2, comprising 88 samples from GEO. RESULTS: We identified 26 immune-related gene pairs as prognostic candidates in discovery cohort. A prognostic immune signature comprising 11 immune gene pairs was constructed in training cohort. In validation cohort 1, the immune signature could significantly distinguish patients with high or low risk in terms of progression-free survival (PFS) (hazard ratio [HR] 2.66, 95 % confidence interval (CI) 1.17-6.02, P=0.015) and could serve as an independent prognostic factor for PFS in multivariate analysis (HR 2.66, 95 % CI 1.17-6.02, P=0.019). Similar results were obtained using validation cohort 2, in which PFS was significantly worse in high risk group than in low risk group (HR 3.02, 95 % CI 1.12-8.18, P=0.022). CONCLUSIONS: The constructed immune signature showed promise for estimating prognosis in NPC. It has potential for translation into clinical practice after prospective validation.

BACKGROUND: Loneliness is a negative emotional state that can lead to physical and mental health problems. This study's objective was to acquire an in-depth understanding of the heterogeneity and the predictors of loneliness among older adults in rural China and provide valuable references for practical interventions. METHODS: Older rural adults in China (N = 680) were recruited between January and April 2023. Latent profile analysis (LPA) was employed to identify subgroups of loneliness among participants. Single-factor and multinomial logistic regression analyses were conducted to investigate predictors of loneliness. RESULTS: The loneliness of rural older adults could be divided into three subgroups: low interaction loneliness group (55.0%), moderate emotional loneliness group (31.8%), and high loneliness group (13.2%). The subgroup predictors included age, gender, religious beliefs, marital status, living alone, number of chronic diseases, and smartphone use (P < 0.05). CONCLUSION: This study identified a classification pattern for loneliness among older adults in rural areas of China, revealed the characteristics of different demographic variables in loneliness categories, and highlighted the heterogeneity of loneliness in this population. It serves as a theoretical reference for formulating intervention plans aimed at addressing various loneliness categories for local rural older adults. CLINICAL TRIAL REGISTRATION: ChiCTR2300071591.

BACKGROUND: This study aimed to investigate the clinical benefit of adding concurrent chemotherapy to intensity-modulated radiotherapy (IMRT) for nasopharyngeal carcinoma (NPC) patients with an intermediate risk (stage II and T3N0M0). METHODS: A multicenter phase II randomized trial was conducted in intermediate-risk NPC patients. Enrolled patients were previously untreated and aged ranged from 18 to 70 years without severe coexisting diseases. Patients were randomly assigned to receive IMRT alone or IMRT+concurrent chemotherapy (CC; three cycles of 80â¯mg/m2 cisplatin every 3 weeks). Primary endpoint was defined as 3year progression-free survival (PFS). The secondary endpoints were distant metastasis-free survival (DMFS), locoregional relapse-free survival (LRRFS), overall survival (OS), and treatment-associated toxicity. We registered this study with Chinese Clinical Trial Registry (CliCTR1800017132; registered July 13, 2018, study start July 13, 2018). RESULTS: From November 2015 to July 2019, 42 patients with stage II and T3N0M0 NPC were enrolled; 20 patients received IMRT alone while 22 patients received IMRT+CC. After a median of 58 months of follow-up, we estimated the 3year PFS rates as 90% (IMRT group) and 86.4% (IMRT+CC group; hazard ratio 1.387, 95% confidence interval 0.240-8.014; Pâ¯= 0.719). The 3year PFS, OS, and cumulative DMFS and LRRFS showed no significant differences between the two groups (Pâ¯> 0.05). However, the IMRT group displayed a lower incidence of nausea/vomiting, leucopenia, and dry mouth than the IMRT+CC group. CONCLUSION: Adding CC to IMRT provided no survival benefit but increased treatment-associated toxicities in patients with intermediate-risk NPC.
RESUMEN
BACKGROUND: This study explores the effect of sensory-based static balance training on the balance ability, aging attitude, and perceived stress of older adults in the community. It provides a practical basis for the in-depth implementation and revision of the community health management model. METHODS: A randomized controlled intervention study was conducted from 2022 to 2023. A total of 72 older adults were recruited and randomly divided into an intervention group (36 individuals) and a control group (36 individuals). Balance ability (measured by the Short Physical Performance Battery and One Leg Stand Test), aging attitudes, and perceived stress were assessed at baseline and at the 12-week and 24-week follow-ups. Repeated-measures ANOVA and generalized estimating equations were used to compare outcome measures. RESULTS: Sensory-based static balance training was beneficial for balance ability and aging attitude among participants in the intervention group. At the end of the intervention, participants in the intervention group showed significant improvements in SPPB scores and OLST scores compared with the control group (FSPPB = 12.347, P = 0.001, Waldχ2OLST = 45.530, P < 0.001), as well as significant differences in aging attitudes (FAAQ = 18.549, P < 0.001). Multiple comparisons at different time points in the intervention group reveal a significant intervention effect (FSPPB = 29.211, Waldχ2OLST = 80.428, FAAQ = 45.981, all P < 0.05). However, the difference in perceived stress before and after the intervention was not significant (FCPSS = 2.876, P = 0.095). CONCLUSIONS: Sensory-based static balance training significantly improved balance ability and aging attitudes among older adults in the community. The effect on perceived stress among older adults in the community was not significant. TRIAL REGISTRATION: Registered in the Chinese Clinic on 04/06/2022. The registration number is ChiCTR2200060541.

BACKGROUND: This study directs to evaluate the efficacy and safety of intensity-modulated radiotherapy (IMRT) alone versus IMRT plus chemotherapy in intermediate-risk NPC (stage II and T3N0M0). METHODS: A total of 124 patients with stage II and T3N0M0 NPC were pair-matched (1:1 ratio) to form two groups: an IMRT-alone group and an IMRT/chemotherapy group. Survival outcomes (overall survival [OS], disease-free survival [DFS], locoregional relapse-free survival [LRRFS], distant metastasis-free survival [DMFS]) and treatment-related grade 3-4 acute toxicity events were compared between the groups. RESULTS: Survival outcomes for patients with stage II and T3N0M0 NPC were quiet comparable between patients treated with IMRT alone versus patients treated with IMRT/chemotherapy: 5-year OS was 91.9% vs. 90.3%, respectively (P = 0.727); DFS was 87.1% vs. 88.7%, respectively (P = 0.821); LRFFS was 96.8% vs. 95.2%, respectively (P = 0.646), and DMFS was 91.9% vs. 91.5%, respectively (P = 0.955). Grade 3 acute toxicities were significantly higher with IMRT/chemotherapy than with IMRT alone: mucositis, 15% vs. 5% (P = 0.004); leukopenia/neutropenia, 8% vs. 1% (P < 0.015); and nausea/vomiting, 22% vs. 3% (P < 0.001). CONCLUSION: For intermediate-risk (stage II and T3N0M0) NPC patients, the addition of chemotherapy to IMRT does not appear to provide any survival benefit. Moreover, grade 3 acute toxicities are also more common in patients receiving IMRT plus chemotherapy.

PURPOSE: To compare the clinical results and functional outcomes between two-dimensional conventional radiation therapy (2DRT) and intensity-modulated radiation therapy (IMRT) in nasopharyngeal carcinoma (NPC) with skull-base invasion. METHODS: A total of 1258 patients were subclassified into two groups: mild skull-base invasion group (792; 63%) and severe skull-base invasion group (466; 37%). Patients were pair matched (1:1 ratio) using six clinical factors into 2DRT or IMRT groups. The Kaplan-Meier method and Cox regression model were performed to assess overall survival (OS), disease-free survival (DFS), locoregional relapse-free survival (LRRFS) and distant metastasis-free survival (DMFS). Toxicities were evaluated. RESULTS: IMRT significantly improved four-year OS compared with 2DRT (65.6% vs. 81.8%, P = 0.000), DFS (57.3% vs. 73.3%, P = 0.000) and LRRFS (76.5% vs. 87.5%, P = 0.003) in NPC with severe skull-base invasion, but similar results were observed in patients with mild skull-base invasion (P > 0.05). In patients with severe invasion, radiation therapy techniques were found to be an independent prognostic factor for OS (HR = 0.457, P = 0.000), DFS (HR = 0.547, P = 0.000) and LRRFS (HR = 0.503, P = 0.004). IMRT was associated with better OS. In subgroups analysis, IMRT group also had a better survival in OS, DFS (P < 0.05 for all rates) for patients received concurrent chemotherapy and sequential chemotherapy compared to 2DRT in the severe invasion group. The IMRT group displayed lower incidence of mucositis, xerostomia, trismus (< 1 cm) and temporal lobe necrosis than the 2DRT group. CONCLUSIONS: IMRT significantly improved patient survival compared with 2DRT in NPC patients with severe skull-base invasion, but a similar survival rate was noted in mild invasion patients. Chemotherapy can improve survival in NPC patients with severe invasion. Among the two therapies, IMRT significantly decreased therapy-related toxicity.

PURPOSE: The efficacy and tolerability of adding chemotherapy to radiotherapy in the era of intensity-modulated radiation therapy (IMRT) remain controversial among older patients with nasopharyngeal carcinoma (NPC). The present study compared IMRT alone with IMRT in combination with chemotherapy in elderly NPC patients. METHODS: Between January 2011 and December 2014, 102 patients aged >65 years with NPC who received IMRT alone (IMRT group) or IMRT in combination with chemotherapy (IMRT/CT group) were enrolled. Patients from both treatment arms were pair-matched (1:1 ratio) based on six clinical factors. Differences in overall survival (OS), disease-free survival (DFS), locoregional relapse-free survival (LRRFS), and distant metastasis-free survival (DMFS) were assessed using the Kaplan-Meier method and Cox proportional hazards models, whereas the toxicity profile was assessed using Common Terminology Criteria for Adverse Events (CTCAE) version 4. RESULTS: No significant differences were noted in OS (72.1% vs. 72.5%, pâ¯= 0.799), DFS (65.9% vs. 70.1%, pâ¯= 0.733), LRRFS (76.4% vs. 71.6%, pâ¯= 0.184), and DMFS (90.8% vs. 98.0%, pâ¯= 0.610) between the IMRT and IMRT/CT groups. Multivariate analyses showed that chemotherapy was not an independent factor for OS, DFS, LRRFS, and DMFS. However, the incidences of grade 3 vomiting/nausea (pâ¯= 0.000), leukopenia/neutropenia (pâ¯= 0.000), thrombocytopenia (pâ¯= 0.041), and anemia (pâ¯= 0.040) were significantly higher in the IMRT/CT group compared with the IMRT group. No grade 4 toxicities were observed. CONCLUSION: IMRT alone was similar to IMRT/CT in treating elderly NPC patients (age >65 years), with comparable survival outcomes and less grade 3 toxicities.

BACKGROUND: The objective of this study was to evaluate the efficacy and safety of gemcitabine plus cisplatin concurrent chemoradiotherapy (CCRT) in patients with nasopharyngeal carcinoma. METHOD: Patients with NPC were randomly assigned to the gemcitabine plus cisplatin (GP) group or fluorouracil plus cisplatin (PF) group. Primary end-point was disease-free survival (DFS); secondary endpoints: overall survival, distant metastasis-free survival (DMFS), locoregional relapse-free survival, and treatment-related adverse events. RESULTS: Seventy-six patients were prospectively enrolled and the median follow-up time was 41 months (9-61 months). Three-year DFS were similar between the GP and PF groups (73.7% vs. 60.5%, HR 0.66, 95% CI 0.30-1.44; P = 0.30). Distant metastasis was the most common failure form in PF compared with GP (P = 0.034). Three-year DMFS was significantly better in the GP group than PF group (89.5% vs. 71.1%, P = 0.045). Grade 3-4 gastrointestinal toxicities (vomiting and diarrhea) were significantly more common in the PF group; grade 3-4 neutropenia and thrombocytopenia were more common in the GP group. CONCLUSION: Gemcitabine plus cisplatin could be used as an alternative regimen in CCRT for nasopharyngeal carcinoma.

OBJECTIVES: The efficacy of various chemotherapy regimens in nasopharyngeal carcinoma (NPC) remains under debate. We compared the efficacy and toxicity of a taxane-based regimen and regimen including fluorouracil in NPC. MATERIALS AND METHODS: Eight-hundred and six patients with stage II-IVB NPC from four institutions in China were pair-matched (1:1 ratio) to the cisplatin plus fluorouracil (PF) group or cisplatin plus taxanes (TP) group using eight clinical factors. Overall survival (OS), disease-free survival (DFS), locoregional relapse-free survival (LRRFS) and distant metastasis-free survival (DMFS) were assessed using the Kaplan-Meier method and Cox regression model. Toxicities were assessed in all patients. RESULTS: Three-year DFS was significantly better in the TP group than PF group (82.5% vs. 72.7%, P=0.002), with no significant difference in OS, LRRFS or DMFS. TP led to significantly better DFS compared to PF in the subgroups advanced stage NPC, patients aged ≤45-years-old and female patients. In multivariate analysis, chemotherapy regimen was an independent prognostic factor for DFS [hazard ratio, 0.591, 95% CI 0.444-0.786, P=0.000]. Grade 3-4 leukopenia, neutropenia and anemia were significantly more common in the TP group; grade 3-4 mucositis, vomiting, vasculitis and diarrhea were more common in the PF group. CONCLUSION: Taxane-based regimens have a higher efficacy in NPC than regimens including fluorouracil, especially in patients with advanced stage, patients aged≤45-years-old and female patients.
