Prognostic utility of the geriatric nutritional risk index for head and neck cancer: Systematic review and meta-analysis.

We conducted a systematic review of the literature to assess the potential prognostic utility of geriatric nutritional risk index (GNRI) for head and neck cancer (HNC). We selected studies and extracted data after searching the Cochrane Library, EMBASE, and PubMed databases. The associations between GNRI and survival outcomes were explored by calculating hazard ratios (HRs) and 95% confidence intervals (CIs) through a random-effects meta-analysis. We included 11 studies that involved 2887 patients with HNC. The combined HR demonstrated significant associations of low GNRI with unfavorable progression-free survival (HR = 1.87, 95% CI = 1.32-2.65, p < 0.001) and overall survival (HR = 3.04, 95% CI = 2.30-4.03, p < 0.001). The association between the GNRI and overall survival persisted across various subgroups. The GNRI could serve as a valuable prognostic biomarker for patients with HNC. Low GNRI scores are significantly associated with unfavorable survival outcomes.

Prognostic importance of modified geriatric nutritional risk index in oral cavity squamous cell carcinoma.

We probed the associations of preoperative modified geriatric nutritional risk index (mGNRI) values with prognosis in patients receiving surgery for oral cavity squamous cell carcinoma (OCSCC). This retrospective study analyzed the clinical data of 333 patients with OCSCC and undergoing surgery between 2008 and 2017. The preoperative mGNRI was calculated using the following formula: (14.89/C-reactive protein level) + 41.7 × (actual body weight/ideal body weight). We executed receiver operating characteristic curve analyses to derive the optimal mGNRI cutoff and employed Kaplan-Meier survival curves and Cox proportional hazard model to probe the associations of the mGNRI with overall survival (OS) and disease-free survival (DFS). The optimal mGNRI cutoff was derived to be 73.3. We noted the 5-year OS and DFS rates to be significantly higher in the high-mGNRI group than in the low-mGNRI group (both p < 0.001). A preoperative mGNRI below 73.3 was independently associated with unfavorable DFS and OS. A mGNRI-based nomogram was constructed to provide accurate OS predictions (concordance index, 0.781). Hence, preoperative mGNRI is a valuable and cost-effective prognostic biomarker in patients with OCSCC. Our nomogram facilitates the practical use of mGNRI and offers individualized predictions of OS.

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.

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.

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.

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.

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.

Low Pretreatment Albumin-to-Globulin Ratios Predict Poor Survival Outcomes in Patients with Head and Neck Cancer: A Systematic Review and Meta-analysis.

Background: Studies have indicated that a low albumin-to-globulin ratio (AGR) before treatment is linked to poor prognosis of many cancers, but the prognostic impact of AGR remains controversial in head and neck cancer (HNC). This meta-analysis examined the prognostic value of AGR in HNC. Methods: We systematically searched the Embase, PubMed, and Cochrane library for relevant articles from inception to July 22, 2022. Studies conducted from 2000 to 2022 exploring the prognostic value of AGR in HNC were retrieved. We employed a random-effects model and calculated pooled hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) to examine the associations of AGR with survival outcome. Results: Our analysis included nine studies involving 3211 patients with HNC. The pooled results revealed significant associations between low pretreatment AGRs and poor disease-free survival (HR = 1.97, 95% CI 1.58-2.45, p < 0.001), distant metastasis-free survival (HR = 1.64, 95% CI 1.25-2.16, p < 0.001), overall survival (HR = 2.18, 95% CI 1.65-2.88, p < 0.001), T3-T4 status (OR = 2.22, 95% CI 1.43-3.44, p < 0.001), stage III-IV disease (OR = 2.62, 95% CI 1.62-4.23, p < 0.001), and lymph node metastasis (OR = 1.95, 95% CI 1.29-2.82, p = 0.001) in patients with HNC. Conclusion: AGR can serve as a prognostic biomarker in managing HNC, and a low pretreatment AGR is strongly associated with adverse survival outcomes and advanced cancer status. Additional large-scale prospective trials must be conducted to assess the validity of our findings.

Prognostic Value of Neutrophil Percentage-to-Albumin Ratio in Patients with Oral Cavity Cancer.

This study investigated preoperative neutrophil percentage-to-albumin ratio (NPAR) for predicting oral cavity squamous cell carcinoma (OSCC) survival. We retrospectively analyzed 368 patients who received curative OSCC surgery between 2008 and 2017. Receiver operating characteristic curve analyses were employed to identify the optimal NPAR cutoff (16.93), and the patients were then separated into low-NPAR and high-NPAR groups. Intergroup differences in survival were determined through Kaplan−Meier analysis and log-rank tests. Disease-free survival (DFS) and overall survival (OS) predictors were identified using Cox proportional-hazards models. A nomogram integrating independent prognostic factors was proposed to increase the accuracy of OS prediction. A high NPAR (≥16.93) was associated with worse median OS and DFS than was a low NPAR (both p < 0.001); this finding was confirmed through multivariate analyses (hazard ratio (HR) for OS = 2.697, p < 0.001; and HR for DFS = 1.671, p = 0.008). The nomogram's favorable predictive ability was confirmed by the calibration plots and concordance index (0.784). The preoperative NPAR is thus a promising prognostic biomarker in patients with OSCC after external validation in a larger cohort. Our nomogram can facilitate clinical use of the NPAR and provides accurate individualized OS predictions.

Prognostic Value of CRP-Albumin-Lymphocyte (CALLY) Index in Patients Undergoing Surgery for Oral Cavity Cancer.

Background: The prognostic value of the CRP-albumin-lymphocyte index (CALLY index) was analyzed in patients with oral cavity squamous cell carcinoma (OSCC) undergoing curative surgery. Methods: We retrospectively included 279 patients who were diagnosed as having primary OSCC and being treated with surgery. The optimal cutoff for the preoperative CALLY index was identified by considering the area under the receiver operating characteristic curve; subsequently, the discriminatory ability of the cutoff was determined. We employed Kaplan-Meier analysis and the log-rank test to elucidate associations between the CALLY index and survival outcomes. We identified prognostic variables by using the Cox proportional hazards model. Finally, we devised a nomogram based on the CALLY index for predicting individualized survival. Results: The cutoff value of the CALLY index was determined to be 0.65. A CALLY index < 0.65 exhibited a significant association with pathological aggressiveness as well as shorter overall and disease-free survival (OS and DFS, both P < 0.001). A low CALLY index was an independent risk factor for short OS and DFS [hazard ratio = 3.816; 95% confidence interval (CI) 2.393-6.086; P < 0.001; and hazard ratio = 2.103; 95% CI 1.451-3.049; P < 0.001, respectively] in multivariate Cox analysis. The prognostic nomogram based on the CALLY index yielded accurate predictions of OS, as revealed by a concordance index of 0.797. Conclusions: The preoperative CALLY index is easy and inexpensive to calculate and, in patients with OSCC, can be a valuable prognostic biomarker. The CALLY-index-based nomogram established in this study provides accurate survival predictions.

Prospective Evaluation of Taste Function in Patients With Head and Neck Cancer Receiving Intensity-Modulated Radiotherapy.

Importance: The majority of the patients with head and neck cancer (HNC) experience taste dysfunction (TD) during or after radiotherapy (RT). However, prospectively collected data for taste dysfunction have been limited, especially in the era of intensity-modulated RT (IMRT). Objective: To evaluate the taste function in patients with HNC receiving IMRT by investigating the association between time course and recovery of TD in both acute and late phases. Design, Setting, and Participants: From August 2017 to November 2020, patients treated at the Chang Gung Memorial Hospital with curative or postoperative IMRT for HNC were enrolled in this prospective cohort study. The data analysis was performed from March 2021 to January 2022. Exposures: IMRT with and without concurrent chemotherapy. Main Outcomes and Measures: Taste function was measured using the whole-mouth solution method for 4 tastes (salt, sweet, sour, and bitter). Subjective evaluations (National Cancer Institute Common Terminology Criteria for Adverse Events [version 4.03] and Subjective Total Taste Acuity scale) were used. Patient self-reported quality of life was evaluated using European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module (EORTC QLQ-H&N35). Results: A total of 87 patients (78 [90%] men and 9 [10%] women; mean [range] age, 58 [31-80] years) were enrolled. Overall TD rates were 79 of 86 (91.9%), 63 of 83 (75.9%), 27 of 81 (33.3%), 5 of 56 (8.9%), and 2 of 30 (6.7%) during RT, and 1 week, 3 months, 6 months, and 1 year after RT, respectively. Positive correlation occurred between objectively measured taste loss for the 4 taste qualities and subjective perception of taste loss. Only oral cavity mean dose 4000 cGy or greater predicted TD 3 months after RT. The mean oral cavity doses to the predicted 15% (D15), 25% (D25), and 50% (D50) probabilities were 25, 38, and 60 Gy at 3 months and 57, 60, and 64 Gy at 6 months, respectively. Conclusions and Relevance: In this cohort study, most patients still experienced TD during and at 3 months after RT. Only a few patients experienced long-term TD. A high oral cavity dose was associated with TD in patients with HNC receiving IMRT. Reducing oral cavity dose may promote early recovery of taste function after IMRT.

Prognostic Role of High-Sensitivity Modified Glasgow Prognostic Score for Patients With Operated Oral Cavity Cancer: A Retrospective Study.

AIM: We probed the prognostic value of the preoperative high-sensitivity modified Glasgow prognostic score (HS-mGPS), neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR) for patients with oral cavity squamous cell carcinoma (OSCC) to identify patients with the highest risk of having poor survival outcomes. MATERIALS AND METHODS: We executed a retrospective assessment of the records of 303 patients with OSCC who had been subjected to curative surgery between January 2008 and December 2017. The HS-mGPS was categorized using C-reactive protein and albumin thresholds of 3 mg/L and 35 g/L, respectively. Moreover, receiver operating characteristic curve analyses were executed to find out the optimal PLR and NLR cutoffs. We plotted survival curves and compared them through the use of the Kaplan-Meier method and log-rank test, respectively. Through a Cox proportional hazard model, we identified prognostic variables. We also plotted a nomogram comprising the HS-mGPS and clinicopathological factors and assessed its performance with the concordance index. RESULTS: The PLR and NLR cutoffs were 119.34 and 4.51, respectively. We noted an HS-mGPS of 1-2 to be associated with a shorter median overall survival (OS) and disease-fee survival (DFS) compared with an HS-mGPS of 0. Multivariate analysis revealed that an HS-mGPS of 1-2 and an NLR of ≥4.51 were independent risk factors related to poor OS and DFS. The HS-mGPS appeared to have better prognostic effect than did the PLR and NLR, and the combination of the HS-mGPS and NLR appeared to exhibit optimal discriminative ability for OS prognostication. The nomogram based on the HS-mGPS and NLR yielded accurate OS prediction (concordance index = 0.803). CONCLUSION: Our findings suggest that preoperative HS-mGPS is a promising prognostic biomarker of OSCC, and the nomogram comprising the HS-mGPS and NLR provided accurate individualized OSCC survival predictions.

Preoperative prognostic nutritional index predicts prognosis of patients with oral cavity cancer.

OBJECTIVE: To investigate whether prognostic nutritional index (PNI) predicts patient survival outcomes in oral cavity squamous cell carcinoma (OSCC). MATERIALS AND METHODS: The data of a total of 360 patients subjected to primary surgery for OSCC were retrospectively analysed. Patients were categorised into high-PNI (≥51.75) and low-PNI (<51.75) groups based on the PNI cut-off value attained from receiver operating characteristic analyses (p < .001), and the intergroup differences in clinicopathological features were determined. The Kaplan-Meier method and Cox proportional hazard model were employed to determine the survival prediction ability of the PNI, and a nomogram based on the PNI was established for individualised survival prediction. RESULTS: A low PNI was noted to exhibit a significant association with shorter overall survival (OS) and disease-free survival (DFS) (both p < .001). Multivariate Cox analyses showed that a lower PNI independently indicated shorter OS and DFS (hazard ratio [HR] = 2.187; p = .001 and HR = 1.459; p = .023, respectively). The concordance index and calibration plots of the PNI-based nomogram revealed the high discriminative ability for OS. CONCLUSIONS: Preoperative PNI is a valuable biomarker for predicting OSCC prognosis, and the proposed PNI-based nomogram can provide individualised prognostic prediction.

Advanced Lung Cancer Inflammation Index Predicts Survival Outcomes of Patients With Oral Cavity Cancer Following Curative Surgery.

AIM: The aim of our study was to investigate the prognostic value of preoperative advanced lung cancer inflammation index (ALI) and to establish prognostic nomograms for the prediction of survival outcomes in patients with oral cavity squamous cell carcinoma (OSCC). MATERIALS AND METHODS: A total of 372 patients who received primary curative surgery for OSCC during 2008-2017 at a tertiary referral center were enrolled. We used the receiver operating characteristic curve to determine the optimal cutoff point of ALI. Through a Cox proportional hazards model and Kaplan-Meier analysis, we elucidated the ALI-overall survival (OS) and ALI-disease-free survival (DFS) associations. Prognostic nomograms based on ALI and the results of multivariate analysis were created to predict the OS and DFS. We used the concordance indices (C-indices) and calibration plots to assess the discriminatory and predictive ability. RESULTS: The results revealed that the ALI cutoff was 33.6, and 105 and 267 patients had ALI values of <33.6 and ≥33.6, respectively. ALI < 33.6 significantly indicated lower OS (44.0% vs. 80.1%, p < 0.001) and DFS (33.6% vs. 62.8%; p < 0.001). In multivariate analysis, ALI < 33.6 was independently associated with poor OS and DFS (both p < 0.001). The C-indices of established nomograms were 0.773 and 0.674 for OS and DFS, respectively; moreover, the calibration plots revealed good consistency between nomogram-predicted and actual observed OS and DFS. CONCLUSION: ALI is a promising prognostic biomarker in patients undergoing primary surgery for OSCC; moreover, ALI-based nomograms may be a useful prognostic tool for individualized OS and DFS estimations.

Survival-Weighted Health Profiles in Patients Treated for Advanced Oral Cavity Squamous Cell Carcinoma.

OBJECTIVES: For patients with oral cavity squamous cell carcinoma (OSCC), particularly for those with advanced disease, quality of life (QoL) is a key outcome measure. Therefore, we estimated survival-weighted psychometric scores (SWPS), life expectancy (LE), and quality-adjusted LE (QALE) in patients with advanced OSCC. METHODS AND MATERIALS: For estimation of survival function, we enrolled 2313 patients with advanced OSCC diagnosed between January 1, 2007, and December 31, 2013. The patients were followed until death or December 31, 2014. To acquire the QoL data, data from 194 patients were collected by employing the Taiwan Chinese versions of the Quality of Life Questionnaire Core 30 and Quality of Life Questionnaire Head and Neck 35 developed by the European Organisation for Research and Treatment of Cancer and the EQ-5D-3L between October 1, 2013, and December 31, 2017. The LE of the patients with OSCC were estimated through linear extrapolation of a logit-transformed curve. SWPS and QALE were determined by integrating the LE and corresponding QoL outcomes. RESULTS: For the patients with advanced OSCC, the estimated LE and QALE were 8.7 years and 7.7 quality-adjusted life years (QALYs), respectively. The loss of LE and QALE was 19.0 years and 20.0 QALYs, respectively. The estimated lifetime impairments of swallowing, speech, cognitive functioning, physical functioning, social functioning, and emotional functioning were 8.3, 6.5, 6.5, 6.1, 5.7, and 5.4 years, respectively. The estimated lifetime problems regarding mouth opening, teeth, social eating, and social contact were 6.6, 6.1, 7.5, and 6.1 years, respectively. The duration of feeding tube dependency was estimated to be 1.6 years. CONCLUSIONS: Patients with advanced OSCC had an estimated LE of 8.7 years and QALE of 7.7 QALYs. SWPS provided useful information regarding how advanced OSCC affects the subjective assessment of QoL. Our study results may serve as a reference for the allocation of cancer treatment resources.

Survival-Weighted Health Profiles in Nasopharyngeal Cancer Patients.

INTRODUCTION: In treating nasopharyngeal cancer (NPC) patients, excellent tumor control and patient survival rates can be achieved in the era of intensity-modulated radiotherapy (IMRT). However, treatment-related toxicities affect the quality of life (QoL) of NPC survivors. This study was devised to estimate the life expectancy (LE), quality-adjusted life expectancy (QALE) and survival-weighted psychometric scores (SWPS) in NPC patients. METHODS: A sample of 875 non-metastatic NPC patients diagnosed between January 1, 2009 and June 30, 2013 was collected for estimation of lifetime survival function. All patients were followed up until death or censored on December 31, 2015. To obtain the utility and psychometric score for estimation of LE, QALE, and SWPS, 99 patients were measured with the Taiwanese version of the EuroQol instrument (EQ-5D) and the Taiwan Chinese versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 and QLQ-H&N35 between October 1, 2013 and December 31, 2017. By utilizing linear extrapolation of a logit-transformed curve, the LE of NPC patients can be estimated. The QALE and SWPS can be obtained by combining the LE and the corresponding QOL function. RESULTS: The mean age of the 875 non-metastatic NPC patients was 50.3 years. The estimated average LE and QALE for NPC patients and for the reference population were 15.5 years and 14.3 quality-adjusted life years (QALYs) and 29.5 years and 29.5 QALYs, respectively. On average, the estimated lifelong duration of pain and painkiller use were 6.0 years and 2.2 years. The estimated lifelong duration of impairment of swallowing, speech, smell and taste were 14.0, 9.8, 8.7, and 7.5 years, respectively. The estimated lifelong duration of problems with dry mouth, teeth, emotion, fatigue, sleep, and social contact were 13.4, 10.1, 9.1, 12.3, 6.7, and 4.5 years, respectively. The estimated lifelong duration of tube-feeding was 1.3 months. CONCLUSIONS: The estimated LE and QALE for NPC patients were 15.5 years and 14.3 QALYs. Furthermore, SWPS could help people understand more about the impact of radiotherapy on NPC patients. These data could also be useful for policy makers to allocate limited resources in health care.

Retrospective study on the potential of albumin/globulin ratio as a prognostic biomarker for oral cavity cancer patients.

PURPOSE: Although the serum albumin/globulin ratio (AGR) is recognized as a valuable prognostic biomarker in various cancers, its clinical value in oral cavity squamous cell carcinoma (OSCC) is still unclear. We aimed to probe the prognostic value of AGR in patients with OSCC undergoing curative surgery. METHODS: This retrospective study analyzed 306 patients who were newly diagnosed as having OSCC and receiving curative surgery between 2008 and 2017. The correlation of AGR with survival outcomes was estimated using Cox proportional hazards models and Kaplan-Meier analysis. A nomogram based on AGR was established, and its accuracy was assessed according to the concordance index. RESULTS: The log rank test and Kaplan-Meier analysis indicated that patients who had low AGR had significantly shorter disease-free survival (DFS) as well as 5-year overall survival (OS) than those with high AGR. The multivariate Cox analysis revealed that low AGR was an independent predictor of poor OS and DFS (adjusted hazard ratio [aHR] = 2.812; 95% CI 1.729-4.573; p < 0.001, and aHR = 1.743; 95% CI 1.201-2.530; p = 0.003, respectively). The concordance index of the nomogram model based on TNM staging alone was 0.656 and could increase to 0.783 with the inclusion of AGR and other prognostic variables in the calculation. CONCLUSION: Preoperative AGR may represent an accessible, valuable prognostic biomarker in patients with OSCC. The nomogram model incorporating AGR and clinicopathological prognostic variables may improve the accuracy of prognostic predictions in these patients.

Association of malnutrition with postoperative complication risk after curative surgery for oral cancer: Observational study.

ABSTRACT: Malnutrition is common among patients who have oral cavity squamous cell carcinoma (OSCC), but its effect on the incidence of postoperative complications remains uncertain. Validated nutrition and complication assessment tools were used to evaluate the effects of nutrition on the likelihood of postoperative complications after curative surgery for OSCC.A retrospective study that spanned January 2014 to December 2018 enrolled 70 patients who received curative surgery for OSCC. Nutritional status before surgery was evaluated with the scored Patient-Generated Subjective Global Assessment (PG-SGA), and patients were classified as either well-nourished (rating A) or malnourished (ratings B and C). Complications 30 days after the operation were graded using Clavien-Dindo classification. The perioperative clinicopathological characteristics of the groups were compared, and risk factors for postoperative complications were identified through logistic regression.A total of 44 (62.8%) patients formed the malnourished group, and they tended to be older (P = .03), weigh less (P = .001), have lower Body Mass Index (P = .003), higher PG-SGA scores (P < .001), higher neutrophil-to-lymphocyte ratio (P = .034), more postoperative complications (P < .001), and longer hospital stays (P = .021). Major complications (Clavien-Dindo classification ≥ IIIa) were experienced by 18.5% (n = 13) of patients and were more common in the malnourished group (P = .007). Multivariate logistic regression demonstrated that PG-SGA score ≥4 was an independent risk factor for postoperative complications (hazard ratio = 4.929, P = .008).Malnutrition defined using the PG-SGA is an independent risk factor for postoperative complications of curative surgery in patients with OSCC. More prospective studies are warranted to confirm our findings.
