Comparing the clinical outcomes of initial surgery and primary definitive radiotherapy with a dosage of 6600 cGy or higher in cT1-2N0M0 oral cavity squamous cell carcinoma: A nationwide cohort study.

BACKGROUND: To compare the clinical outcomes of two treatment modalities, initial surgery and primary definitive radiotherapy (RT), in Taiwanese patients diagnosed with cT1-2N0M0 oral cavity squamous cell carcinoma (OCSCC). METHODS: Between 2011 and 2019, we analyzed data for 13,542 cT1-2N0M0 patients who underwent initial surgery (n = 13,542) or definitive RT with a dosage of at least 6600 cGy (n = 145) for the treatment of OCSCC. To account for baseline differences, we employed propensity score (PS) matching, resulting in two well-balanced study groups (initial surgery, n = 580; definitive RT, n = 145). RESULTS: Before PS matching, the 5-year disease-specific survival (DSS) rates were 88% for the surgery group and 58% for the RT group. After PS matching, the 5-year DSS rates of the two groups were 86% and 58%, respectively. Similarly, the 5-year overall survival (OS) rates before PS matching were 80% for the surgery group and 36% for the RT group, whereas after PS matching, they were 73% and 36%, respectively. All these differences were statistically significant (p < 0.0001). A multivariable analysis identified treatment with RT, older age, stage II tumors, and a higher burden of comorbidities as independent risk factors for both DSS and OS. We also examined the 5-year outcomes for various subgroups (margin ≥5 mm, margin <5 mm, positive margins, RT combined with chemotherapy, and RT alone) as follows: DSS, 89%/88%/79%/63%/51%, respectively, p < 0.0001; OS, 82%/79%/68%/39%/32%, respectively, p < 0.0001. CONCLUSIONS: In Taiwanese patients with cT1-2N0M0 OCSCC, a remarkably low proportion (1.1%) completed definitive RT. A significant survival disparity of 30% was observed between patients who underwent initial surgery and those who received definitive RT. Interestingly, even patients from the surgical group with positive surgical margins exhibited a significantly superior survival compared to those in the definitive RT group.

The effects of diabetes, hypertension and subsequent health control behavior on the survival of a Taiwan cohort aged over 50 years.

Purpose: This study used the Taiwan Longitudinal Study in Aging from 1996 to 2011 to investigate the effects of diabetes, hypertension, and healthy living behaviors of those aged over 50 years on the survival status in Taiwan. Methods: Among the 5,131 participants aged 50 years and above in the 1996 survey were included in this study. Cox's proportional hazards model was used to examine the incidence of diabetes, hypertension, and related mortality risk in those aged over 50 years. Results: After adjusting for age, gender, education level, diabetes, hypertension, health behavior, and leisure activity, results from the Cox model show that the elderly without diabetes have a lower mortality risk than those with diabetes. Regular exercise was associated with a lower risk of mortality. The hazard ratios of elderly with regular exercise were 0.78 (95 % CI: 0.64-0.96) for two times a week or less, 0.81 (95 % CI: 0.69-0.96) for 3-5 times a week, and 0.84 (95 % CI: 0.77-0.93) for 6 + times a week, respectively. On the other hand, leisure activity positively reduces mortality risk. For example, the hazard ratios of the elderly with watching TV and reading were 0.63 (95 % CI: 0.55-0.72) and 0.80 (95 % CI: 0.72-0.89), respectively. Moreover, smoking can increase mortality risk 23 % whether the elderly are with diabetes or hypertension or not. Conclusions: Regarding preventing and controlling chronic diseases in the future, continuously encouraging improvement in health behavior and engaging in leisure activities for the middle-aged and over should be considered essential markers.

Nasal Patency Across Seated, Supine, and Recumbent Postures in Individuals With and Without Allergic Rhinitis.

Objectives: This study aimed to investigate the effects of seated, supine, and recumbent postures on nasal resistance in individuals with allergic rhinitis (AR) and healthy controls, which has not been investigated in the past. Methods: A visual analog scale (VAS) assessed subjective nasal obstruction, while acoustic rhinometry and video endoscopy provided objective measures. Sixty participants, comprising 30 AR patients and 30 healthy controls, were evaluated across 4 postures without decongestion: seated, supine, left recumbent, and right recumbent. Results: In patients with AR, we noted no significant changes in subjective nasal blockage under various postures (all P > .18). However, significant reductions of minimal cross-sectional area (mCSA) were found (seated vs supine, P = .014; seated vs left recumbent, P = .001; seated vs right recumbent, P < .001) and significant increases in the inferior turbinate hypertrophy were observed on the dependent side of the nose when in recumbent posture (right nose: seated vs right recumbent, P = .013; left nose: seated vs left recumbent, P = .003). On the contrary, healthy controls experienced increased subjective nasal obstruction (VAS scores: seated vs supine, P < .001; seated vs left recumbent, P = .003; seated vs right recumbent, P < .001), reductions in mCSA (seated vs supine, P = .002; seated vs right or left recumbent, both P = .001), and increased inferior turbinate hypertrophy on the dependent side of the nose (right nose: seated vs right recumbent, P = .003; left nose: seated vs left recumbent, P = .006). Conclusions: Healthy controls reported better nasal patency when shifting from supine or recumbent to more upright or less gravity-dependent seated postures, which was further supported by objective examinations. On the contrary, despite patients with AR not subjectively perceiving increased nasal patency while adopting more upright postures, objective evaluations demonstrated an improvement in their nasal airflow in these less gravity-dependent postures.Level of Evidence: 4.

The benefits of leisure activities on healthy life expectancy for older people with diabetes.

PURPOSE: The purpose of this study is to examine whether leisure activities can help reduce years lived with disability and increase healthy life expectancy of diabetics aged 50 years and above. METHODS: Analysis was based on five waves of follow-up survey data (Taiwan Longitudinal Study of Aging, TLSA) from 1996 to 2011. A total of 5131 participants aged 50 years and above in 1996 were included in the analysis, and gender, leisure activity participation, and diabetes mellitus were used as primary variables to examine the variation trend in health status in the participants. The health status in the various waves of surveys was measured using the activities of daily living scale, and nondisabled was defined as healthy. A multivariate logistic regression model was used to calculate the life expectancy (LE) and healthy life expectancy (HLE) of the people aged 50 years and above. RESULTS: The diabetes older people with a high frequency of leisure activities have longer HLE than those with lower activity frequency. Using 50-year-old diabetic women as an example, the LE (HLE) of those with six or more leisure activities and those with three or fewer leisure activities was 30.40 (25.34) and 24.90 (20.87), respectively. The LE (HLE) of men with the same conditions was 24.79 (22.68) and 20.30 (18.45), respectively. CONCLUSIONS: This study used life expectancy and healthy life expectancy as markers to evaluate health benefits and provided evidence that leisure activities can help extend the life span and maintain the health status of middle-aged and older diabetics.

Survival-weighted quality of life profiles in patients treated for laryngeal and hypopharyngeal cancers.

Objectives: This study assessed functional outcomes and quality of life (QoL) in the long term in individuals treated for laryngohypopharyngeal cancer (LHC) by estimating their life expectancy (LE), survival-weighted psychometric scores (SWPSs), and quality-adjusted LE (QALE). Materials and methods: To estimate survival outcomes, we retrospectively reviewed the data of 1576 patients treated for primary LHC between January 2010 and December 2018 and followed them until death or December 2020. We also prospectively collected QoL and functional data between October 2013 and November 2022 from 232 patients by administering the Taiwanese Chinese versions of the QoL Questionnaire Core 30, Head and Neck 35, and EQ-5D-3L. To estimate LE, we employed linear extrapolation of a logit-transformed curve. We calculated QALE and SWPSs by combining the QoL data with the LE results. Results: We estimated the LE of the patients with LHC to be 7.8 years and their loss of LE to be 15.7 years. The estimated QALE was 7.0 QALYs, with a loss of QALE of 16.5 QALYs. Lifetime impairment durations were estimated for cognitive (4.9 years), physical (4.2 years), emotional (3.4 years), social (3.4 years), and role functions (2.7 years). We estimated the durations of problems related to swallowing, speech, and teeth to be 6.2, 5.6, and 4.8 years, respectively. The patients were expected to be dependent on feeding tubes for 1.2 years. Conclusions: Patients with LHC experience significant reductions in both LE and QALE. SWPSs may constitute a valuable tool for obtaining subjective information regarding how LHC affects multifaceted QoL outcomes.

Microbial Analysis in Chronic Rhinosinusitis Patients with Chronic Kidney Disease and End-Stage Renal Disease.

INTRODUCTION: This study aimed to elucidate the bacterial profile of chronic rhinosinusitis (CRS) in patients with end-stage renal disease (ESRD) and chronic kidney disease (CKD) compared with nonrenal patients, guiding antibiotic selection for clinicians. METHODS: We retrospectively analyzed 13,906 inpatients from the Chang Gung Research Database who underwent sinus surgery (2004-2018). Patients were categorized into ESRD-CRS, CKD-CRS, and non-CKD-CRS based on the estimated glomerular filtration rate. Bacterial cultures from surgical samples were classified as facultative anaerobes or aerobes (e.g., Klebsiella pneumoniae [KP], Pseudomonas aeruginosa [Ps.a]), anaerobes, and fungi and ranked by prevalence. RESULTS: Data from 47 ESRD-CRS, 230 CKD-CRS, and 13,123 non-CKD-CRS patients were analyzed. In ESRD-CRS, the predominant species were KP (31.6%), Ps.a (21.1%), and Coagulase-negative Staphylococcus (CoNS, 15.8%). CKD-CRS showed Staphylococcus epidermidis (27.7%), CoNS (20.5%), and Ps.a (20.5%). Non-CKD-CRS had Staphylococcus epidermidis (29.8%), CoNS (25.0%), and Staphylococcus aureus (15.5%). For anaerobes, ESRD-CRS was dominated by Fusobacterium nucleatum (10.5%) and Peptostreptococcus micros (10.5%), whereas CKD-CRS and non-CKD-CRS showed Propionibacterium acnes as a primary strain (14.5% and 28.7%, respectively). CONCLUSION: For CRS in ESRD, antibiotics targeting KP and Fusobacterium nucleatum are recommended. In CKD-CRS, a focus on Staphylococcus epidermidis and Propionibacterium acnes is suggested.

Should sub-millimeter margins be deemed positive in oral cavity squamous cell carcinoma?

BACKGROUND: While several studies have indicated that a margin status of < 1 mm should be classified as a positive margin in oral cavity squamous cell carcinoma (OCSCC), there is a lack of extensive cohort studies comparing the clinical outcomes between patients with positive margins and margins < 1 mm. METHODS: Between 2011 and 2020, we identified 18,416 Taiwanese OCSCC patients who underwent tumor resection and neck dissection. Of these, 311 had margins < 1 mm and 1013 had positive margins. To compare patients with margins < 1 mm and those with positive margins, a propensity score (PS)-matched analysis (n = 253 in each group) was conducted. RESULTS: The group with margins < 1 mm displayed a notably higher prevalence of several variables: 1) tongue subsite, 2) younger age, 3) smaller depth of invasion), 4) early tumor stage, and 5) treatment with surgery alone. Patients with margins < 1 mm demonstrated significantly better disease-specific survival (DSS) and overall survival (OS) rates compared to those with positive margins (74 % versus 53 %, 65 % versus 43 %, both p < 0.0001). Multivariable analysis further confirmed that positive margins were an independent predictor of worse 5-year DSS (hazard ratio [HR] = 1.38, p = 0.0103) and OS (HR = 1.28, p = 0.0222). In the PS-matched cohort, the 5-year outcomes for patients with margins < 1 mm compared to positive margins were as follows: DSS, 71 % versus 59 %, respectively (p = 0.0127) and OS, 60 % versus 48 %, respectively (p = 0.0398). CONCLUSIONS: OCSCC patients with a margin status < 1 mm exhibited distinct clinicopathological characteristics and a more favorable prognosis compared to those with positive resection margins.

A Study on Decision-Making for Improving Service Efficiency in Hospitals.

The provision of efficient healthcare services is essential, driven by the increasing demand for healthcare resources and the need to optimize hospital operations. In this context, the motivation to innovate and improve services while addressing urgent concerns is critical. Hospitals face challenges in managing internal dispatch services efficiently. Outsourcing such services can alleviate the burden on hospital staff, reduce costs, and introduce professional expertise. However, the pressing motivation lies in enhancing service quality, minimizing costs, and exploring innovative approaches. With the rising demand for healthcare services, there is an immediate need to streamline hospital operations. Delays in internal transportation services can have far-reaching implications for patient care, necessitating a prompt and effective solution. Drawing upon dispatch data from a healthcare center in Taiwan, this study constructed a decision-making model to optimize the allocation of hospital service resources. Employing simulation techniques, we closely examine how hospital services are currently organized and how they work. In our research, we utilized dispatch data gathered from a healthcare center in Taichung, Taiwan, spanning from January 2020 to December 2020. Our findings underscore the potential of an intelligent dispatch strategy combined with deployment restricted to the nearest available workers. Our study demonstrates that for cases requiring urgent attention, delay rates that previously ranged from 5% to 34% can be notably reduced to a much-improved 3% to 18%. However, it is important to recognize that the realm of worker dispatch remains subject to a multifaceted array of influencing factors. It becomes evident that a comprehensive dispatching mechanism must be established as part of a broader drive to enhance the efficiency of hospital service operations.

Is elective neck dissection justified in cT2N0M0 oral cavity cancer defined according to the AJCC eighth edition staging system?

BACKGROUND: The current NCCN guidelines recommend considering elective neck dissection (END) for early-stage oral cavity squamous cell carcinoma (OCSCC) with a depth of invasion (DOI) exceeding 3 mm. However, this DOI threshold, determined by evaluating the occult lymph node metastatic rate, lacks robust supporting evidence regarding its impact on patient outcomes. In this nationwide study, we sought to explore the specific indications for END in patients diagnosed with OCSCC at stage cT2N0M0, as defined by the AJCC Eighth Edition staging criteria. METHODS: We examined 4723 patients with cT2N0M0 OCSCC, of which 3744 underwent END and 979 were monitored through neck observation (NO). RESULTS: Patients who underwent END had better 5-year outcomes compared to those in the NO group. The END group had higher rates of neck control (95% vs. 84%, p < 0.0001), disease-specific survival (DSS; 87% vs. 84%, p = 0.0259), and overall survival (OS; 79% vs. 73%, p = 0.0002). Multivariable analysis identified NO, DOI ≥5.0 mm, and moderate-to-poor tumor differentiation as independent risk factors for 5-year neck control, DSS, and OS. Based on these prognostic variables, three distinct outcome subgroups were identified within the NO group. These included a low-risk subgroup (DOI <5 mm plus well-differentiated tumor), an intermediate-risk subgroup (DOI ≥5.0 mm or moderately differentiated tumor), and a high-risk subgroup (poorly differentiated tumor or DOI ≥5.0 mm plus moderately differentiated tumor). Notably, the 5-year survival outcomes (neck control/DSS/OS) for the low-risk subgroup within the NO group (97%/95%/85%, n = 251) were not inferior to those of the END group (95%/87%/79%). CONCLUSIONS: By implementing risk stratification within the NO group, we found that 26% (251/979) of low-risk patients achieved outcomes similar to those in the END group. Therefore, when making decisions regarding the implementation of END in patients with cT2N0M0 OCSCC, factors such as DOI and tumor differentiation should be taken into account.

Dispatchers trained in persuasive communication techniques improved the effectiveness of dispatcher-assisted cardiopulmonary resuscitation.

BACKGROUND: Early recognition of cardiac arrest and early initiation of bystander cardiopulmonary resuscitation can increase the survival of patients with out-of-hospital cardiac arrest (OHCA). We compared dispatcher-assisted cardiopulmonary resuscitation (DACPR) effectiveness before and after using different communication models in the dispatching center. METHOD: We analyzed dispatch recordings of non-trauma origin OHCA cases received by the Taichung dispatch center between May 1 to September 30, 2021, and November 1, 2021, to March 31, 2022. The dispatchers underwent an 8-hour training intervention consisting of targeted education using a new communication model for DACPR. Several outcome measures were evaluated, including the sustained return of spontaneous circulation and the time to first chest compression. RESULTS: We included 640 cases in the preintervention group and 580 cases in the postintervention group. The return of spontaneous circulation (ROSC) rate, the time to first chest compression, and good neurological outcome were significantly improved in the postintervention group (20.9% vs. 31.0%, p < 0.001;168 seconds vs. 151 seconds, p = 0.004; 2.8% vs. 5.3%, p = 0.024, respectively). In subgroup analyses, the intervention was related to a statistical improvement in ROSC rate among patients whose caller was a family member (18.7% vs. 31.4%, p < 0.001). Among patients whose caller was female, both ROSC and good neurological outcome significantly improved after the intervention (19.8% vs. 36.6%, p < 0.001; 2.7% vs. 7.5%, p = 0.006, respectively). There was a statistical difference between the pre-intervention and post-intervention group with respect to ROSC rate among patients whose caller was family (the adjusted odds ratio:1.78, 95% CI: 0.59-1.25], p < 0.001.) or female (the adjusted odds ratio:3.18,95% CI: 1.77-5.70], p = 0.008.) in the multivariable regression model. CONCLUSION: The new communication model has enhanced the effectiveness of DACPR in terms of the ROSC rate, particularly when the caller was a family member or female, leading to improved rates of ROSC and favorable neurological outcomes.

Prognostic utility of preoperative platelet-to-albumin ratio in surgically treated oral cavity cancer patients.

BACKGROUND: This study aimed to explore the prognostic utility of the preoperative platelet-to-albumin ratio (PAR) among patients with oral cavity squamous cell carcinoma (OSCC). METHODS: We retrospectively reviewed of 355 patients with surgically-treated OSCC between 2008 and 2017. The optimal PAR cutoff for patient stratification was determined through X-tile analysis. Prognostic variables for disease-free survival (DFS) and overall survival (OS) were identified using Cox proportional hazards models. We developed a PAR-based nomogram to predict personalized OS. RESULTS: We determined the optimal PAR cutoff to be 7.45. A PAR of ≥7.45 was an independent negative prognostic factor for DFS and OS (hazard ratio = 1.748 and 2.386; p = 0.005 and p < 0.001, respectively). The developed nomogram demonstrates the practical utility of PAR and accurately predicts personalized OS. CONCLUSIONS: The preoperative PAR is a promising and cost-effective prognostic biomarker for patients with surgically-treated OSCC; the PAR-based nanogram accurately predicts OS for such patients.

Sublabial excision versus transnasal endoscopic marsupialization for nasolabial cysts: A systematic review and meta-analysis.

OBJECTIVES: To compare the intraoperative and postoperative outcomes of sublabial excision and transnasal endoscopic marsupialization, the two primary surgical approaches for nasolabial cysts. DESIGN AND SETTING: A comprehensive meta-analysis of studies identified from PubMed, Embase, and the Cochrane Library. PARTICIPANTS: Patients diagnosed with nasolabial cysts who underwent surgical treatment. MAIN OUTCOME MEASURES: Operative time, postoperative pain, overall postoperative complications, admission rate, length of hospital stay, use of general anaesthesia, medical costs, and recurrence rate. RESULTS: The pooled analysis revealed that the transnasal endoscopic marsupialization group had shorter operative time (mean differences [MD], -32.51; 95% confidence interval [CI], -38.52 to -26.51), reduced postoperative pain (MD, -4.25; 95% CI, -7.62 to -0.89), fewer overall postoperative complications (risk difference [RD], -0.68; 95% CI, -0.90 to -0.46), lower admission rates (RD, -0.86; 95% CI, -1.11 to -0.61), shorter hospital stays (MD, -1.74; 95% CI, -2.58 to -0.89), decreased use of general anaesthesia (RD, -0.40; 95% CI, -0.76 to -0.03), and reduced medical costs (MD, -229.69; 95% CI, -338.64 to -120.75). The recurrence rate between the two groups showed no significant difference (RD, -0.01; 95% CI, -0.05 to 0.04). CONCLUSION: Transnasal endoscopic marsupialization presents as a promising alternative to sublabial excision in the treatment of nasolabial cysts. It offers advantages like reduced operative time, decreased postoperative pain, fewer complications, lower admission rates, shorter hospital stays, diminished need for general anaesthesia, and cost savings. Clinicians can leverage these findings to select the most suitable surgical approach for their patients.

Prognostic utility of neutrophil-to-albumin ratio in surgically treated oral squamous cell carcinoma.

BACKGROUND: We aimed to evaluate the prognostic significance of preoperative neutrophil-to-albumin ratio (NAR) in oral squamous cell carcinoma (OSCC). METHODS: A total of 622 patients with surgically treated OSCC were enrolled. NAR was defined as the absolute neutrophil count divided by the serum albumin level in peripheral blood before the radical surgery. Cox proportional hazards model were used to discover survival outcome-associated factors. RESULTS: The optimal cut-off of NAR to predict overall survival (OS) was determined to be 0.1. In Cox model, high NAR was identified as an independent negative prognosticator of OS, cancer-specific survival, and recurrence-free survival (adjusted hazard ratio: 1.503, 1.958, and 1.727, respectively; all p < 0.05). The NAR-based nomogram accurately predicted OS (concordance index: 0.750). CONCLUSION: Our study suggests that preoperative NAR is a convenient and effective prognostic marker for OSCC and NAR-based nomogram can be a promising prognostic tool in clinical setting.

Prognostic Utility of Neck Lymph Node-to-Primary Tumor Standardized Uptake Value Ratio in Oral Cavity Cancer.

We investigated the prognostic utility of preoperative neck lymph node-to-primary tumor maximum standardized uptake value ratios (NTRs) in oral cavity squamous cell carcinoma (OSCC). We retrospectively reviewed the medical records of 141 consecutive patients who were diagnosed as having OSCC and had received fluorodeoxyglucose-positron emission tomography within 2 weeks prior to radical surgery between 2009 and 2018. To determine the optimal NTR cutoff, receiver operating characteristic analysis for overall survival (OS) was executed. The NTR's prognostic value for disease-free survival (DFS) and OS were determined through Cox proportional hazards analysis and the Kaplan-Meier method. We determined the median (range) follow-up duration to be 35.2 (2.1-122.4) months. The optimal NTR cutoff was 0.273, and patients with a higher NTR (≥0.273) exhibited significantly worse DFS and OS (p = 0.010 and 0.003, respectively). A higher NTR (≥0.273) predicted poorer DFS (hazard ratio: 2.696, p = 0.008) and OS (hazard ratio: 4.865, p = 0.003) in multivariable analysis. We created a nomogram on the basis of the NTR, and it could accurately predict OS (concordance index: 0.774). Preoperative NTRs may be a useful prognostic biomarker for DFS and OS in patients with OSCC who have undergone surgery. NTR-based nomograms may also be helpful prognostic tools in clinical trials.

The prognostic utility of preoperative geriatric nutritional risk index on survival outcomes of locally advanced oral cancer.

PURPOSE: This retrospective cohort study was to assess the prognostic value of preoperative geriatric nutritional risk index (GNRI) on survival outcomes for patients with locally advanced oral squamous cell carcinoma (LAOSCC). METHODS: Patients with LAOSCC receiving upfront radical surgery at a single institute from January 2007 to February 2017 were enrolled. The primary outcomes in the study were 5-year overall survival (OS) and cancer-specific survival (CSS) rates, and a nomogram based on GNRI and other clinical-pathological factors was established for individualized OS prediction. RESULTS: There were 343 patients enrolled in this study. The optimal cut-off value of GNRI was observed to be 97.8. Patients in the high-GNRI group (GNRI ≥97.8) had statistically significantly better outcomes in 5-year OS (74.7% vs. 57.2%, p = 0.001) and CSS (82.2% vs. 68.9%, p = 0.005) when compared with the low-GNRI group (GNRI <97.8). In Cox models, low GNRI remained an independent negative prognosticator of OS (HR: 1.6; 95% CI: 1.124-2.277; p = 0.009) and CSS (HR: 1.907; 95% CI: 1.219-2.984; p = 0.005). The c-index of the proposed nomogram, incorporating assorted clinicopathological factors and GNRI, had a statistically significant increase compared with the predictive nomogram constructed by the TNM staging system alone (0.692 vs. 0.637, p < 0.001)." CONCLUSION: Preoperative GNRI is an independent prognostic factor of OS and CSS in patients with LAOSCC. A multivariate nomogram that includes GNRI may better help us to accurately estimate individual survival outcomes.

Postoperative radiotherapy alone is as effective as postoperative chemoradiotherapy in patients with pT4aN0 gingival cancer with negative surgical margins.

Background and purpose: This study compared the survival outcomes following postoperative chemoradiotherapy (CCRT) and postoperative radiotherapy (RT) alone for patients with gingival cancer with negative surgical margins and only bone invasion. Materials and methods: Of the 2579 gingival cancer cases reviewed from 2002 to 2018, 156 were enrolled in the study (CCRT: 63 patients; RT: 93 patients). The primary endpoints were the impact of adjuvant treatment (RT vs. CCRT) on overall survival (OS), locoregional recurrence-free survival (LRRFS), and distant metastasis-free survival (DMFS). Subgroup analyses were conducted based on surgical margins (<5 mm vs. ≥ 5 mm) and different adjuvant treatments (RT vs. CCRT). Results: Median follow-up time, age, and invasion depth were 88.5 months, 57 years, and 14 mm, respectively. More patients undergoing adjuvant CCRT had surgical margins < 5 mm (47.6% vs. 21.5%, p < 0.01) than those undergoing RT. No significant difference was observed in the 5-year OS, LRRFS, and DMFS of patients undergoing adjuvant RT and CCRT. Although adjuvant RT alone and CCRT provided similar local control for patients with surgical margins ≥ 5 mm, worse LRRFS trends were observed in patients with surgical margins < 5 mm (hazards ratio, 6.15, 95% confidence interval 0.92-41.13, p = 0.06). Conclusion: Postoperative RT alone may be effective for patients with gingival cancer with negative surgical margins (≥5 mm) and only bone invasion, while postoperative CCRT may result in better LRRFS than RT alone for patients with surgical margins < 5 mm.

Utility of modified Glasgow prognostic score for head and neck squamous cell carcinoma: Systematic review and meta-analysis.

Whether the modified Glasgow prognostic score (mGPS) is useful for patients with head and neck squamous cell carcinoma (HNSCC) remains controversial. An electronic database search on EMBASE, PubMed, and the Cochrane Library from inception to 30 June 2022 was performed for study selection and data extraction. The associations between the mGPS and survival outcomes were evaluated using a random-effects meta-analysis and expressed as pooled hazard ratios (HRs) and 95% CIs. We included 11 studies involving a total of 2017 patients with HNSCC. A higher mGPS was associated with poorer progression-free survival (HR = 2.39, 95% CI 1.69-3.38), overall survival (HR = 2.40, 95% CI 1.94-2.98), disease-specific survival (HR = 2.57, 95% CI 1.71-3.88), and disease-free survival (HR = 2.67, 95% CI 1.51-4.73, all p ≤ 0.001) in HNSCC. The mGPS can function as a valid prognostic biomarker for patients diagnosed as having HNSCC.

A Nomogram Incorporating Neutrophil-to-Lymphocyte Ratio and Squamous Cell Carcinoma Antigen Predicts the Prognosis of Oral Cancers.

We introduced a novel squamous cell carcinoma inflammatory index (SCI) and explored its prognostic utility for individuals with operable oral cavity squamous cell carcinomas (OSCCs). We retrospectively analyzed data from 288 patients who were given a diagnosis of primary OSCC from January 2008 to December 2017. The SCI value was derived by multiplying the serum squamous cell carcinoma antigen and neutrophil-to-lymphocyte ratio values. We appraised the associations of the SCI with survival outcomes by performing Cox proportional hazards and Kaplan-Meier analyses. We constructed a nomogram for survival predictions by incorporating independent prognostic factors in a multivariable analysis. By executing a receiver operating characteristic curve analysis, we identified the SCI cutoff to be 3.45, and 188 and 100 patients had SCI values of <3.45 and ≥3.45, respectively. The patients with a high SCI (≥3.45) were associated with worse disease-free survival and overall survival than those with a low SCI (<3.45). An elevated preoperative SCI (≥3.45) predicted adverse overall survival (hazard ratio [HR] = 2.378; p < 0.002) and disease-free survival (HR = 2.219; p < 0.001). The SCI-based nomogram accurately predicted overall survival (concordance index: 0.779). Our findings indicate that SCI is a valuable biomarker that is highly associated with patient survival outcomes in OSCC.

Nasal Patency in Sitting, Supine, and Prone Positions in Individuals with and without Allergic Rhinitis.

(1) Background: Physiological changes in nasal patency in response to posture contribute to sleep-related problems. Previously, we reported that the supine and prone positions cause a significant decrease in nasal patency in subjective and objective assessments of healthy individuals. Therefore, we conducted a study to evaluate the effect of posture on nasal patency in patients with allergic rhinitis (AR); (2) Methods: The present study comprised 30 patients diagnosed with AR and 30 healthy subjects without nasal disease (non-AR). Changes in nasal patency were evaluated in the sitting, supine, and prone positions. We used the visual analog scale to evaluate subjective nasal blockage. Acoustic rhinometry and endoscopy were used to objectively measure changes in nasal patency; (3) Results: In the non-AR group, the prone position had a significant effect on subjective nasal blockage compared with the sitting position, with significant decreases in the minimal cross-sectional area (mCSA) measured by acoustic rhinometry. Furthermore, endoscopy demonstrated a significantly increased inferior turbinate hypertrophy in the non-AR group. In the AR group, there was no statistical difference in subjective nasal blockage symptoms between the different positions. However, in objective examinations (acoustic rhinometry and endoscopy), the prone position showed significantly decreased nasal patency; (4) Conclusions: In patients with AR, subjective nasal blockage did not significantly increase in the supine or prone position. Endoscopy demonstrated increased inferior turbinate hypertrophy in supine and prone positions resulting in a significant reduction in nasal cavity mCSA, indicating an objective reduction in nasal patency.

Prognostic impact of the hemoglobin-albumin-lymphocyte-platelet score in patients with oral cavity cancer undergoing surgery.

BACKGROUND: We aimed to probe the hemoglobin-albumin-lymphocyte-platelet (HALP) score's prognostic value in oral cavity squamous cell carcinoma (OSCC). METHODS: Medical data of 350 patients with primary operated OSCC were retrospectively reviewed. We derived the optimal HALP cutoff by executing receiver operating characteristic curve analysis, and patients were then grouped based on this cutoff value. Cox proportional hazards model were used to discover survival outcome-associated factors. RESULTS: We derived the optimal HALP cutoff as 35.4. A low HALP score (<35.4) predicted poorer overall and disease-free survival (hazard ratio: 2.29 and 1.92, respectively; both p < 0.001) and was significantly associated with OSCC aggressiveness. We established a HALP-based nomogram that accurately predicted overall survival (concordance index: 0.784). CONCLUSION: The HALP score may be a useful prognostic biomarker in patients with OSCC undergoing surgery, and the HALP-based nomogram can be a promising prognostic tool in clinical setting.
