Outcomes in surgical management of sinonasal malignancy—A single comprehensive cancer center experience

xlomafota13 shared this article with you from Inoreader Outcomes in surgical management of sinonasal malignancy—A single comprehensive cancer center experience Via Head & Neck Abstract Background Sinonasal malignancies are a complex and diverse group of tumors. Over the past five decades, treatment advances have changed the management paradigms for these tumors. Our aim was to analyze the outcomes of patients from a comprehensive cancer center. Materials and Methods We retrospectively assessed 400 patients with sinonasal malignancies treated with surgery at our center between 1973 and 2015. Multiple variables were reviewed to assess the influence on 5-year outcomes. Results The median age was 56 years (IQR 46.8–68). Two hundred and fifty-nine (65%) were males and 141 (35%) were females. Overall survival (OS) and disease-specific survival (DSS) improved in the last analyzed decade. Orbital invasion, advanced pT-classification and pN-classification, and melanoma histology were associated with poorer outcomes. Conclusion Treatment outcomes for patients with sinonasal malignancy have improved over time. This is likely multifactorial with advances in surgical technique, adjuvant treatment, and patient selection. pT-classification, pN-classification, orbital invasion, and histology are predictive of survival.

Sensitizing TRAIL response via differential modulation of anti- and pro-apoptotic factors by AZD5582 combined with ER nanosomal TRAIL in neuroblastoma

xlomafota13 shared this article with you from Inoreader Sensitizing TRAIL response via differential modulation of anti- and pro-apoptotic factors by AZD5582 combined with ER nanosomal TRAIL in neuroblastoma Via histochem Acta Histochem. 2022 Jan 22;124(2):151856. doi: 10.1016/j.acthis.2022.151856. Online ahead of print. ABSTRACT Neuroblastoma is a metastatic brain tumor particularly common in children. The cure rate is below 50% for patients of high-risk condition. Novel therapeutic agents and approaches are needed to improve the cure rate. Tumor necrosis factor-related and apoptosis-inducing ligand (TRAIL) is a promising proapoptotic factor that rapidly induces apoptosis preferentially in t ransformed and cancerous cells. Unfortunately, the common TRAIL resistance in cancers has hampered the clinical application of the ligand. Previously we prepared a novel TRAIL-armed ER derived nanosomal agent (ERN-T) that overcomes TRAIL resistance in some cancer lines when combined with a synthetic antagonist of inhibitors of apoptosis proteins (IAPs), AZD5582. However, how AZD5582 sensitizes cancer cells to ERN-T remains not well understood. In this study we continued to test the therapeutic efficacy of the combinatory therapy of ERN-T and AZD5582 on neuroblastoma, aiming to reveal the molecular mechanism underlying the synergism between AZD5582 and ERN-T. The obtained data revealed that ERN-Ts overcame TRAIL resistance and showed significant cytotoxicity on the resistant neuroblastoma line SH-SH5Y when combined with AZD5582 whilst sparing normal cells. The combination of low doses of ERN-Ts and AZD5582 induced intensive apoptosis in SH-SY5Y but not in normal skin fibroblasts (NSF s). Importantly we discovered that TRAIL sensitization in SH-SY5Y was associated with the concomitant downregulation of antiapoptotic factors cFLIP, MCL-1 and IAPs and upregulation of proapoptotic protein BAX and the death receptor 5 (DR5) by the cotreatment of ERN-T and AZD5582. In vivo study demonstrated that the combination of ERN-T and AZD5582 constituted a highly effective and safe therapy for subcutaneous SH-SY5Y xenograft neuroblastoma in nude mice. In conclusion, we identified that the concomitant regulation of both antiapoptotic and proapoptotic factors and DR5 is an essential molecular mechanism for overcoming TRAIL resistance in SH-SY5Y and the combination of ERN-T and AZD5582 potentially constitutes a novel therapeutic strategy, which is highly effective and safe for neuroblastoma.

Objective evaluation of stimulation artefact removal techniques in the context of neural spike sorting

xlomafota13 shared this article with you from Inoreader Objective evaluation of stimulation artefact removal techniques in the context of neural spike sorting Via Laryngologie J Neural Eng. 2022 Jan 25. doi: 10.1088/1741-2552/ac4ecf. Online ahead of print. ABSTRACT Objective - We present a framework to objectively test and compare stimulation artefact removal techniques in the context of neural spike sorting. Approach - To this end, we used realistic hybrid ground-truth spiking data, with superimposed artefacts from in vivo recordings. We used the framework to evaluate and compare several techniques: blanking, template subtraction by averaging, linear regression, and a multi-channel Wiener filter (MWF). Main results - Our study demonstrates that blanking and template subtraction result in a poorer spike sorting performance than linear regression and MWF, while the latter two perform similarly. Finally, to validate the conclusions found from the hybrid evaluation framework, we also performed a qualitative analysis on in vivo recordings without artificial manipulations. Significance - Our framework allows direct quan tification of the impact of the residual artefact on the spike sorting accuracy, thereby allowing for a more objective and more relevant comparison compared to indirect signal quality metrics that are estimated from the signal statistics. Furthermore, the availability of a ground truth in the form of single-unit spiking activity also facilitates a better estimation of such signal quality metrics.

Chemosaturation with percutaneous hepatic perfusion of melphalan for metastatic uveal melanoma

xlomafota13 shared this article with you from Inoreader Chemosaturation with percutaneous hepatic perfusion of melphalan for metastatic uveal melanoma Via Melanoma Research - Published Ahead-of-Print Purpose Uveal melanoma, the most common primary ocular malignancy in adults, carries a poor prognosis: 50% of patients develop the metastatic disease with a 10–25% 1-year survival and no established standard of care treatment. Prior studies of melphalan percutaneous hepatic perfusion (M-PHP) have shown promise in metastatic uveal melanoma (mUM) patients with liver predominant disease but are limited by small sample sizes. We contribute our findings on the safety and efficacy of the procedure in the largest sample population to date. Patients and methods retrospective analysis of outcome and safety data for all mUM patients receiving M-PHP was performed. Tumour response and treatment toxicity were evaluated using RECIST 1.1 and Common Terminology Criteria for Adverse Events v5.03, respectively. Results 250 M-PHP procedures were performed in 81 patients (median of three per patient). The analysis demonstrated a hepatic disease control rate of 88.9% (72/81), a hepatic response rate of 66.7% (54/81), and an overall response rate of 60.5% (49/81). After a median follow-up of 12.9 months, median overall progression-free (PFS) and median overall survival (OS) were 8.4 and 14.9 months, respectively. There were no fatal treatment-related adverse events (TRAE). Forty-three grade 3 (29) or 4 (14) TRAE occurred in 23 (27.7%) patients with a significant reduction in such events between procedures performed in 2016–2020 vs. 2012–2016 (0.17 vs. 0.90 per patient, P View on the web Inoreader.

Effectiveness of submucosal turbinoplasty in refractory obstructive rhinitis: a prospective comparative trial

xlomafota13 shared this article with you from Inoreader Effectiveness of submucosal turbinoplasty in refractory obstructive rhinitis: a prospective comparative trial Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Jan 25. doi: 10.1007/s00405-022-07267-0. Online ahead of print. ABSTRACT OBJECTIVE: Refractory inferior turbinate hypertrophy requires a surgical approach to address symptomatic complaints. Submucosal approaches demonstrated their efficacy in restoring respiratory function and respecting the nasal mucosa. Microdebrider-assisted turbinoplasty (MAT) tools effectively reduces the soft tissue, exploiting a very different principle from the kinetic energy of radiofrequency. Thus, we aimed to compare the microdebrider-assisted turbinoplasty and the quantum molecular resonance (QMR) to assess patients' perspectives and respiratory outcomes. METHODS: Subjects with persistent bilateral nasal blockage due to inferior turbinates hypertrophy were prospectively recruited from the University Medical Center. We randomly assigned the patients to each treatment and performed symptom evaluation via the visual analog score and endoscopic assessment at baseline and 30-, 90-, and 180-day post-treatment. RESULTS: Seventy participants completed the evaluations, 35 in MAT and 35 in the QMR group. Nasal complaints were significantly reduced after 1 month using both methods. Although the MAT group reported higher postoperative bleeding and edema than QMR group, similar significant reductions were seen for turbinate size at long-term follow-up. Conversely, the MAT group reported greater VAS outcomes than QMR from the first postoperative month. In addition, MAT showed a longer operating time, although this difference was not statistically significant (p < 0.05). CONCLUSION: MAT allows effective control of nasal symptoms by reducing the size of turbinates in patients with lower turbinate hypertrophy. Although QMR may cause fewer postoperative complications, functional results are comparable to long-term follow-up. PMID:35076746 | DOI:10.1007/s00405-022-07267-0 View on the web Inoreader.

Nutritional status at diagnosis is prognostic for pharyngeal cancer patients: a retrospective study

xlomafota13 shared this article with you from Inoreader Nutritional status at diagnosis is prognostic for pharyngeal cancer patients: a retrospective study Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Jan 25. doi: 10.1007/s00405-021-07222-5. Online ahead of print. ABSTRACT BACKGROUND: Malnutrition in head and neck cancer (HNC) patients is associated with increased morbidity and mortality. Several nutrition indicators have been reported to be related to the prognosis of HNC. However, the prognostic effect of these multiple nutrition factors in HNC is not well elucidated. The aim of this study was to evaluate the prognostic effect of these factors, including the novel hemoglobin, albumin, lymphocyte, and platelet (HALP) score, for pharyngeal cancers. MATERIAL AND METHODS: From 2008 to 2019, a total of 319 pharyngeal cancer patients were recruited. We collected adult patients with a diagnosis of nasopharyngeal carcinoma, oropharyngeal carcinoma and hypopharyngeal carcinoma. Patients who completed definite staging workup and treatment were selected for analysis. We traced nutritional and hematologic al parameters, including body mass index (BMI), albumin, and complete blood count, for survival analysis. RESULTS: We found that multiple nutritional markers, including BMI, hemoglobin, albumin, prognostic nutritional index (PNI), nutritional risk index (NRI) and HALP score, were important predictors for pharyngeal cancers in univariate Cox regression analysis. In multivariate analysis, we found that the HALP score was still an independent factor (HR: 1.62, 1.13-2.32 for overall survival [OS]) after adjusting of gender, age, cancer site, clinical stage, and BMI. The PNI was the most important independent factor for OS (HR: 3.12, 2.18-4.47) and cancer-specific survival (HR: 2.88, 1.88-4.41) in multivariate analysis. CONCLUSION: We found that multiple nutrition markers, including BMI, hemoglobin, albumin, PNI, NRI and HALP score, are important predictors for pharyngeal cancers. This is the first report confirming the prognostic effect of the HALP score for HNCs. Nutritiona l status at diagnosis should be given more attention in pharyngeal cancer patients.

The differences in distant metastatic patterns and their corresponding survival between thyroid cancer subtypes

xlomafota13 shared this article with you from Inoreader The differences in distant metastatic patterns and their corresponding survival between thyroid cancer subtypes Via Head & Neck Abstract Introduction This study aimed to systematically elucidate the metastatic patterns and their corresponding survival of each thyroid cancer subtype at time of diagnosis. Methods We accessed the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2018 to search for primary thyroid cancers with DM at presentation (M1). Results We included 2787 M1 thyroid cancers for statistical analyses and the incidence of DM at presentation was 2.4%. Lung was the most common metastatic site for anaplastic thyroid carcinoma (ATC), poorly differentiated thyroid carcinoma (PDTC), papillary thyroid carcinoma (PTC), and oncocytic (Hurthle) cell carcinoma (HCC) whereas bone is the favorable disseminated site of follicular thyroid carcinoma (FTC) and medullary thyroid carcinoma (MTC). Patients with multi-organ metastases had the worst survival whereas bone metastases were associated with a favorable outcome (p < 0.001). Conclusion There are significant differences in DM patterns of thyroid cancer subtypes and their corresponding survival. View on the web Inoreader. Take back control of your news feed.

xlomafota13 shared this article with you from Inoreader A study of 285 cases of cranial vault suture closure in Chinese adults Via radiol anat Surg Radiol Anat. 2022 Jan 25. doi: 10.1007/s00276-021-02854-y. Online ahead of print. ABSTRACT PURPOSE: To examine the presence and characteristics of cranial vault suture closure in Chinese adults and to explore whether craniosacral therapy (CST) manipulation is rational from the anatomical perspective. METHODS: Anthropological non-metric observation and craniometry were used to study 285 dry skull specimens of Chinese adults. RESULTS: A total of 91 specimens w ith closed extracranial sutures were observed, with an occurrence rate of 31.93%. Based on the mode of closure, there were 32 cases of single type closure, with sagittal suture closure predominating with 20 cases (21.98%); 59 cases of composite closure, with a partial closure of coronal suture + sagittal suture + lambdoid suture predominating with 26 cases (28.57%). In terms of the degree of closure, there were 13 cases (14.28%) of sagittal suture grade 0 closure and 78 cases (85.72%) of grade 1 - 4 closure; 34 cases (37.36%) of coronal suture grade 0 closure and 57 cases (62.64%) of grade 1 - 4 closure; 47 cases (51.65%) of lambdoid suture grade 0 closure and 44 cases (48.35%) of grade 1 - 4 closure. The segment and degree of coronal suture closure (46, 80.7%) and lambdoid suture (31, 70.45%) were mostly left-right symmetrical. The bone surfaces on either side of the cranial vault sutures are embedded in each other, forming a rough, complex and interlocking bone-suture-bone structu re. CONCLUSION: This study observed the closure of the cranial vault suture, summarized its characteristics, and explored the irrationality of the CST manipulation. The anatomical characteristics of the cranial suture dictate that manipulation cannot push the cranial suture at will. PMID:35076751 | DOI:10.1007/s00276-021-02854-y View on the web Inoreader.

MicroRNA-195-5p inhibits the progression of hemangioma via targeting SKI

xlomafota13 shared this article with you from Inoreader MicroRNA-195-5p inhibits the progression of hemangioma via targeting SKI Via Experimental and therapeutic medicine Exp Ther Med. 2022 Feb;23(2):165. doi: 10.3892/etm.2021.11088. Epub 2021 Dec 22. ABSTRACT Hemangioma (HA), which is characterized by aberrant endothelial cell proliferation in blood vessels, is a common tumor during infancy. MicroRNAs (miRNAs/miRs) collectively participate in the development of HA; however, the potential roles of miR-195-5p in HA are not completely understood. The aim of the present study was to investigate the roles of miR-195-5p in HA. In the present study, miR-195-5p was found to be downregulated in HA cells, such as the XPTS-1 human infantile hemangioma-derived endothelial cell line and the EOMA hemangioendothelioma cell line. Overexpression of miR-195-5p was shown to suppress HA cell viability, colony formation and proliferation, and induced HA cell apoptosis. Furthermore, miR-195-5p downregulated Bcl-2 expression and upregulated Bax and Bcl-2 expression levels. V-ski sarcoma viral oncogene homolog (SKI) was ident ified as a target of miR-195-5p. Co-transfection of miR-195-5p mimics and SKI 3'-untranslated region wild-type decreased HA cell luciferase activity. SKI overexpression alleviated the miR-195-5p-induced decrease in HA cell proliferation and increased HA cell apoptosis. In addition, the regulatory role of miR-195-5p on the expression of Bcl-2, Bax and poly(ADP-ribose) polymerase was reversed by SKI. Collectively, the results of the present study demonstrated that miR-195-5p suppressed HA progression and its effects were mediated via SKI. Therefore, the miR-195-5p/SKI axis may represent a novel therapeutic target for HA. PMID:35069846 | PMC:PMC8753966 | DOI:10.3892/etm.2021.11088 View on the web Inoreader.
