Elevated NLR predicts worse outcomes in patients with HNSCC.
Elevated platelet count and PLR are associated with poor prognosis in patients with HNSCC.
Sarcopenia, which is characterized by a decrease in muscle quantity or quality, is commonly observed in patients with cancer. Recent research has reported contradictory results on the association between sarcopenia and the efficacy of immune checkpoint inhibitors (ICIs). We conducted a systematic review and meta-analysis to investigate this discrepancy. We systematically searched three electronic databases to identify articles reporting on the association between sarcopenia and treatment outcomes in patients with solid cancers who received ICIs. The outcomes assessed were hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS), and odds ratios (ORs) for objective response rate (ORR), disease control rate (DCR), and toxicity. Pooled estimates and their 95% confidence intervals (CIs) were calculated. A total of 2501 patients from 26 studies were analysed. Sarcopenia was observed in 44.7% (95% CI: 38.2-51.3) of the patients and was significantly associated with poor survival (HR = 1.55, 95% CI = 1.32-1.82 for OS and HR = 1.61, 95% CI = 1.35 to 1.93 for PFS). The HRs (95% CIs) for OS according to the diagnostic measures used were 1.97 (0.88-4.41) for psoas muscle index (PMI), 1.41 (0.87-2.28) for skeletal muscle density (SMD), and 1.43 (1.23-1.67) for skeletal mass index (SMI). The HRs (95% CIs) for PFS were 1.86 (1.08-3.21) for PMI, 1.27 (0.94-1.71) for SMD, and 1.38 (1.11-1.71) for SMI. Poor radiological response to ICI therapy was observed in patients with sarcopenia (OR = 0.52, 95% CI = 0.34-0.80 for ORR and OR = 0.45, 95% CI = 0.30-0.67 for DCR). The ORs for ORR (95% CIs) were 0.56 (0.15-2.05) for PMI and 0.78 (0.56-1.09) for SMI. The oncologic outcomes associated with melanoma and non-small cell lung cancer (NSCLC) were comparable with those observed overall (HR for OS = 2.02, 95% CI = 1.26-3.24 for melanoma and HR for OS = 1.61, 95% CI = 1.19-2.18 for NSCLC). In contrast, the occurrence of severe toxicity was not associated with sarcopenia (OR = 1.13, 95% CI = 0.51-2.52). Poor survival and poor response in patients with sarcopenia indicate a negative association between sarcopenia and efficacy of ICIs. Sarcopenia's predictive ability is consistent across various tumour types. For the selection of patients who may respond to ICIs pre-therapeutically, the presence of sarcopenia should be assessed in clinical practice.
Background The objective of this study was to compare the prognostic impact of sarcopenia in patients with head and neck cancer (HNC) treated with surgery or radiation. Methods We systematically searched electronic databases to identify articles reporting the impact of sarcopenia on the prognosis of patients with HNC. Hazard ratios (HRs) and 95% confidence intervals (CIs) for overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS) were extracted and pooled. HR according to treatment modality were estimated using random-effects models. Statistical analyses were carried out using the Comprehensive Meta-Analysis software. Results In total, 18 studies enrolling 3,233 patients were included. Sarcopenia was associated with poor OS in both surgery and radiotherapy groups (hazard ratio [HR] 2.50, 95% confidence interval [CI] 1.95–3.21; HR 1.63, 95% CI 1.40–1.90, respectively). The HR was significantly higher in the surgery group than in the radiotherapy group (p = 0.004), with similar results obtained for DFS (HR 2.59, 95% CI 1.56–4.31; HR 1.56, 95% CI 1.24–1.97 for the surgery and radiotherapy groups, respectively) and DSS (HR 2.96, 95% CI 0.73–11.95; HR 2.67, 95% CI 1.51–4.73 for the surgery and RT groups, respectively). Conclusions Sarcopenia was a poor prognostic factor for HNC, regardless of the treatment modality. However, the adverse effects of sarcopenia on survival were more prominent in the surgery group than in the radiotherapy group. Sarcopenia assessment is required for appropriate treatment decision-making.
Objective/HypothesisMeniere's disease (MD) is a common inner ear disease characterized by repeated episodic vertigo, fluctuating sensorineural hearing loss, and tinnitus. Its pathology is defined as endolymphatic hydrops (EH) in the inner ear and EH has been hypothesized to correlate with the clinical symptoms of MD. We presented the dynamics of in vivo EH in MD patients during medical treatments.Study DesignProspective, single‐arm repeated measuresMethodsEleven MD patients were enrolled. All subjects prospectively underwent gadolinium‐enhanced inner ear magnetic resonance (MR) imaging and neuro‐otological testing before and after medical treatment. The volume of EH was quantitatively evaluated by processing MR images. All MD patients were administered continuous medication and followed up for more than 12 months.ResultsThe frequency of vertigo episodes decreased in all patients and vestibular function decreased to 13–91% of the pre‐treatment level. The volume ratio of post‐treatment EH‐to‐pre‐treatment EH ranged from 1.01–3.22. The total volume of pre‐treatment EH was significantly correlated with cochlear symptom disease duration and the affected ear's hearing level.ConclusionEH in MD patients developed longitudinally with deterioration of inner ear function during medical treatment. The natural course of MD may progress with development of EH at least for a certain period.Level of Evidence2b.
Objectives Epistaxis, especially posterior epistaxis, is occasionally refractory to treatment. In these cases, sphenopalatine artery surgeries, including cauterization and ligation, are required. Previous reports have demonstrated treatment results for these procedures but failed to provide high‐level evidence. The aim of this study was to quantify the rates of failure and perioperative complications of these procedures by using a meta‐analysis technique. Methods We systematically searched electronic databases and identified articles regarding epistaxis, sphenopalatine artery ligation, or cauterization. Pooled rebleeding and complication rates were calculated by using a random effects model. Results A total of 896 cases of sphenopalatine ligation or cauterization for epistaxis were analyzed. Pooled rebleeding rates for the entire cohort, cauterization group, and ligation group were 13.4% (95% confidence interval [CI] 10.0–17.8, P < 0.001), 7.2% (95% CI 4.6–11.0, P < 0.001), and 15.1% (95% CI 9.8–22.5, P < 0.001), respectively. Pooled perioperative complication rates for the entire cohort, cauterization group, and ligation group were 8.7% (95% CI 4.9–15.1, P < 0.001), 10.2% (95% CI 3.8–24.5, P < 0.001), and 6.4% (95% CI 1.8–20.9, P < 0.001), respectively. Conclusion Overall, sphenopalatine surgery for refractory epistaxis is an effective method because of its low rates of failure and complications. Cauterization is more effective than ligation, whereas complications are comparable between the two procedures.Laryngoscope, 129:1731–1736, 2019
Objectives/Hypothesis: Meniere's disease (MD) patients can show normal head impulses despite poor caloric test results. This study aimed to investigate the discrepancy in the vestibulo-ocular reflex (VOR) in MD patients and whether endolymphatic hydrops (EH) influence the VOR.Study Design: Prospective, cross-sectional observational study. Methods: Ninety MD patients were enrolled. Neuro-otological testing, including a video head impulse test (vHIT) of all semicircular canals (SCs), and gadolinium-enhanced inner ear magnetic resonance imaging were performed. The vestibular EH volume was quantitatively evaluated by processing magnetic resonance images.Results: Abnormal vHIT results in MD patients were found most frequently in the posterior (44.4%) SCs, followed by the horizontal (13.3%) and anterior (10%) SCs. Canal paresis (CP) was assessed using the vHIT and the caloric test, and results were not significant when vHIT responses were assessed as CP only using the horizontal SC. The difference in the vestibular EH between the presence and absence of CP was not significant if assessed using the vHIT (P = .5591), but it was statistically different if assessed using the caloric test (P = .0467).Conclusions: The contradictory reaction of VOR in MD patients may result from the high specificity but low sensitivity of CP in the horizontal vHIT. EH volume in the vestibule affects the caloric response but does not affect the vHIT response.
BackgroundInflammatory markers are used to predict prognosis of nasopharyngeal carcinoma (NPC). Previous reports of neutrophil-to-lymphocyte ratio (NLR) and NPC mortality are inconsistent. This study aimed to quantify the prognostic impact of NLR on NPC.MethodsThe primary outcome was overall survival (OS), and the secondary outcomes were disease-specific survival (DSS), progression-free survival (PFS) and distant metastasis-free survival (DMFS). We systematically searched electronic databases, identified articles reporting an association between NLR and NPC prognosis. Hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted, and pooled HRs for each outcome were estimated using random effect models.ResultsNine studies enrolling 5397 patients were included in the analyses. NLR greater than the cutoff value was associated with poor overall survival (HR 1.51, 95% CI 1.27–1.78), disease-specific survival (HR 1.44, 95% CI 1.22–1.71), progression-free survival (HR 1.53, 95% CI 1.22–1.90), and distant metastasis-free survival (HR 1.83, 95% CI 1.14–2.95).ConclusionsElevated NLR predicts worse OS, DSS, PFS and DMFS in patients with NPC.
