The Impact

Összefoglaló. Bevezetés: Régóta ismert, hogy a daganatokhoz társuló emelkedett vérlemezkeszám rosszabb túléléssel társul. Fej-nyak tumoros betegek esetében kevés információ áll rendelkezésünkre ezzel az összefüggéssel kapcsolatban. Célkitűzés: Vizsgálatunk célja a fej-nyak daganatos betegek prognózisa és a thrombocytosis közötti összefüggés tanulmányozása volt. Módszer: Különféle stádiumú és lokalizációjú, 312, fej-nyak tumoros beteg retrospektív adatait elemeztük. A műtét előtti vérlemezkeszámokat vizsgáltuk, a 300 G/l feletti értéket tekintettük emelkedett thrombocytaszámnak. A vérlemezkeszám és a túlélés közötti kapcsolatot Kaplan–Meier-módszerrel és multivariáns Cox-regresszióval elemeztük. Eredmények: Emelkedett thrombocytaszám mellett szignifikánsan rosszabb túlélést észleltünk (5 éves túlélés: p = 0,007, betegségmentes túlélés: p = 0,192). Ez az összefüggés még akkor is fennállt, amikor multivariáns analízissel nemre, korra, stádiumra, differenciáltsági fokra, lokalizációra, valamint fehér- és vörösvérsejtszámra korrigáltuk az elemzést (5 éves túlélés: p = 0,027). A különféle anatómiai lokalizációkban eltérő mértékben észleltünk 300 G/l feletti vérlemezkeszámot (algarat: 43,6%, sub- és supraglottis: 35,8%, szájüreg: 35,7%, hangszalag: 22,5%, szájgarat: 19%, multiplex: 50%), ez azonban nem befolyásolta szignifikánsan a túlélést (p = 0,603). Következtetés: A daganathoz társuló thrombocytosis összefüggésbe hozható a fej-nyak tumoros betegek rosszabb túlélésével. Az egyes lokalizációkban talált különböző vérlemezkeszámok nem befolyásolják eltérő mértékben a túlélést. Orv Hetil. 2021; 162(17): 676–682. Summary. Introduction: The association between cancer-related thrombocytosis and worse survival has been described with a variety of solid neoplasms. However, only limited data are available on the prognostic significance of elevated platelet count in head and neck tumours. Objective: We aimed to investigate the correlation between the survival of patients with head and neck cancer and thrombocytosis. Method: We conducted an analysis of the data from 312 patients with head and neck squamous cell carcinoma of various stages and locations. Preoperative platelet counts were analysed; elevated platelet count was defined as 300 G/l or higher. The influence of platelet count on survival was calculated with the Kaplan–Meier method as well as with multivariate Cox regression. Results: In patients with excessive thrombocytosis, survival was significantly worse (overall survival: p = 0.007, disease-free survival: p = 0.192). This association remained significant even after adjusting the multivariate analysis for age, gender as well as tumour stage, grade, location, red and white blood cell count (overall survival: p = 0.027). The magnitude of thrombocytosis differed among tumours of different anatomical locations (hypopharynx: 43.6%, sub- and supraglottis: 35.8%, oral cavity: 35.7%, vocal cord: 22.5%, oropharynx: 19%, multiple: 50%), but this did not affect survival significantly (p = 0.603). Conclusion: Elevated platelet count may be related to a worse prognosis in head and neck squamous cell carcinoma patients. The impact of thrombocytosis does not vary with the anatomical location of the tumour. Orv Hetil. 2021; 162(17): 676–682.

Background: This study aimed to use a bioinformatics pipeline to explore the underlying mechanisms and identify genetic mutations that can be utilized to prognosticate individuals with head and neck squamous cell carcinoma (HNSCC). Methods: SNP-related data was accessed using the TCGA database. Mutation and expression analyses were performed between the mutant samples and wild-type samples. Kaplan‐Meier analysis was conducted to select the candidate mutant genes that affect overall survival. Correlation analysis, GSEA analysis and drug sensitivity analysis of the candidate genes were performed. Results: Down-regulation of FAT1, KMT2B, XIRP2 and ZNF347 expression were observed in the tumors with mutations. Kaplan‐Meier analysis indicated that reduced levels of FAT1, XIRP2 was significantly associated with better overall survival, while reduced levels of KMT2B, and ZNF347 were significantly correlated to worse overall survival. Additionally, SNPs of the four genes were found to participate in several pathways associated with HNSCC development. Furthermore, FAT1 mutation was sensitive to several anti-tumor drugs, such as PI-103, Belinostat and Ruxolitinib. Conclusion: SNPs in FAT1, KMT2B, XIRP2 and ZNF347 may be used as prognostic biomarkers in the treatment of HNSCC.

Significant Difference

Sulfation of heparan sulfate proteoglycans (HSPG) regulates signaling of growth factor receptors via specific interactions with the sulfate groups. 6-O-Sulfation of HSPG is an impactful modification regulated by the activities of dedicated extracellular endosulfatases. Specifically, extracellular sulfatase Sulf-2 (SULF2) removes 6-O-sulfate from HS chains, modulates affinity of carrier HSPG to their ligands, and thereby influences activity of the downstream signaling pathway. In this study, we explored the effect of SULF2 expression on HSPG sulfation and its relationship to clinical outcomes of patients with head and neck squamous cell carcinoma (HNSCC). We found a significant overexpression of SULF2 in HNSCC tumor tissues which differs by tumor location and etiology. Expression of SULF2 mRNA in tumors associated with human papillomavirus (HPV) infection was two-fold lower than in tumors associated with a history of tobacco and alcohol consumption. High SULF2 mRNA expression is significantly correlated with poor progression-free interval and overall survival of patients (n = 499). Among all HS-related enzymes, SULF2 expression had the highest hazard ratio in overall survival after adjusting for clinical characteristics. SULF2 protein expression (n = 124), determined by immunohistochemical analysis, showed a similar trend. The content of 6-O-sulfated HSPG, measured by staining with the HS3A8 antibody, was higher in adjacent mucosa compared to tumor tissue but revealed no difference based on SULF2 staining. LC-MS/MS analysis showed low abundance of N-sulfation and O-sulfation in HS but no significant difference between SULF2-positive and SULF2-negative tumors. Levels of enzymes modifying 6-O-sulfation, measured by RT-qPCR in HNSCC tumor tissues, suggest that HSPG sulfation is carried out by the co-regulated activities of multiple genes. Imbalance of the HS modifying enzymes in HNSCC tumors modifies the overall sulfation pattern, but the alteration of 6-O-sulfate is likely non-uniform and occurs in specific domains of the HS chains. These findings demonstrate that SULF2 expression correlates with survival of HNSCC patients and could potentially serve as a prognostic factor or target of therapeutic interventions.

e18512 Background: Cisplatin-based chemoradiotherapy (CRT) is a well-established regimen used for adjuvant and/or head-and-neck squamous cell carcinoma (HNSCC) radical treatment. The most classic protocol for chemoradiotherapy remains the administration of Cisplatin 100mg/m² EV D1 q3-week period, 3 cycles. The objective of this study is to assess the efficacy and tolerability of the weekly 40mg/m² cisplatin regimen. Methods: we conducted a retrospective study from 2007-2020 with 102 patients treated at a national reference institution. All of them with HNSCC received concurrent CRT with weekly cisplatin 40mg/m² EV D1. We analyzed the overall survival (OS), local recurrence and tolerability in this scheme. Results: The median cisplatin cumulative dose received by our patients was 240mg/m². Hence, we divided them in two groups for the analysis: Group A (41 patients) received less than 240mg/m² cisplatin total dose and Group B (61 patients) received more or equal 240mg/m² cisplatin total dose. Both groups were equally balanced between sex, clinic stage, histologic grade and clinic status. We found that the Group A experienced 5 deaths (12.2%) while the Group B experienced 6 deaths (9.8%). The mean time to recurrence disease in the Group A was 45.68 months and in Group B 60.22 months (p = 0.958). The estimated overall survival in the Group A was 150 months and in the Group B was 116.4 months (p = 0.443). Conclusions: The weekly cisplatin dose regimen showed to be feasible, more tolerable, and less toxic and with no difference in terms of OS then the classic 3-week cisplatin protocol in the CRT setting. Our group suggests that the 240mg/m² cumulative cisplatin weekly schedule should be a better option for CRT treatments then the classic cisplatin regimen. A phase III clinical trial is warranted to further understanding of this framework. Key-words: head and neck cancer, cisplatin, radiotherapy
