Opis:
Introduction: The aim of the study was to analyze the profile of patients who reported for free screening examinations during the 4th European Head and Neck Cancer Awareness Week to the Department of Otolaryngology, Miedzylesie Specialist Hospital, Warsaw, Poland. Material and methods: We enrolled 225 patients, aged 26-92 years (mean, 63 years). There were 149 women (66%) and 76 men (34%). All patients filled out a survey regarding risk factors of head and neck cancer (HNC), including symptoms and lifestyle characteristics. Subsequently, all participants underwent a complete laryngological examination. Results: Among the studied patients, we found the following lifestyle-related risk factors of HNC: tobacco use (22%), alcohol use more than 1 time per week (12%), oral sex (17%), multiple sexual partners (10%), rare dental checkups (24%), and dental prostheses (45%). The most frequent symptoms that prompted the patients to report for screening exams were as follows: chronic hoarseness (64%), xerostomia (39%), dysphagia (37%), nasal congestion (6%), and neck tumor (5%). Further imaging studies were ordered in 15 patients (7%), fiberoscopy in 25 (11%), and lesion excision in 18 (8%). Among the studied patients, 17 were referred for further oncological treatment, of whom 14 had benign tumors and 4 malignant tumors. Conclusions: The Head and Neck Cancer Awareness campaign increased the awareness of HNC, and it should systematically encompass people at increased risk. By implementing this program in our department, we were able to detect and initiate early treatment in 7.5% of the screened people. However, appropriate workup and treatment require funding and therefore systemic measures should be taken to enable a wide implementation of such screening programs.

Opis:
Neuroendocrine carcinoma is a rare neoplasm, and its most common location in the head and neck area is the larynx, especially the epiglottis and the supraglottic region. The first case of neuroendocrine carcinoma of the larynx was reported in 1969 by Goldman et al. Expression of the two crucial markers, synaptophysin and chromogranin, along with neural cell adhesion molecule (CD56) should be mentioned among the neuroendocrine features detected on immunohistochemistry. Human papilloma virus (HPV16/18) infection in the laryngeal neuroendocrine carcinoma can be one of the causal factors, and the detection of HPV should be considered as a standard procedure for the diagnosis and treatment.

Opis:
Introduction. Head and neck haemangiomas occur quite rarely. These are benign lesions, often involving the pharynx and larynx. They almost always pose a diagnostic and therapeutic problem. Case description. This paper describes the case of an asymptomatic internal carotid artery aneurysm manifested by a throat tumour. A 78-year old woman with sudden deafness and vertigo was additionally diagnosed with a throat tumour. After radiological diagnosis of a haemangioma, the patient refused surgery. This article presents diagnostic methods and various types of treatments for head and neck haemangiomas. Attention was paid to the possibility of serious complications when deciding on surgical intervention of haemangiomas without a confirmed diagnosis. Conclusion. Suspicion of head and neck haemangiomas necessitates using all available diagnostic methods. The treatment plan should take into account the pace of progression, the patient’s age and co-morbid conditions. .

Introduction: Dermoid cysts are benign epidermal tumors; in 7% of cases, they are located in the head and neck region. They are lesions of congenital origin, mostly presenting within the midline of the body. About 70% of cases are diagnosed before the age of 5 years. Methods: A retrospective analysis of medical data of children with dermoid cysts located within the head and neck region treated in the Department of Pediatric Otolaryngology in Bialystok in the period of 1994-2014 was performed. A review of relevant literature was presented. Results: A total of 17 patients were included in this study, with a mean age of 8.9 years; 76.5% of the study population was female. Dermoid cysts were mostly located in the anterior neck region and the floor of the mouth (76%). US and CT imaging scans were used in diagnostics. No recurrences were observed after surgical excision. Conclusion: Dermoid cysts should be taken into consideration when diagnosing head and neck masses in pediatric patients.

Opis:
Introduction. Cancer is a complex pathological process that develops in the human body, destroying healthy cells progressively and leading to significant limitations in functioning and severe pain, sometimes persissitng even with the aid of painkillers. Cancerous diseases of the head and neck organs significantly reduce the quality of life compared to the population of healthy people. Aim. The aim of this study was to show whether smoking, alcohol and HPV are risk factors for head and neck cancer. Materials and methods. The study was conducted among 149 patients diagnosed with head and neck cancer in the Clinical Outpatient Center of Oncology Center in Gliwice with the consent of this heaktcare facility. The study used a questionnaire containing 38 questions. The study was carried out from November 2016 to January 2017. Results. The analysis of the results did not confirm that smoking, alcohol and HPV are the main risk factors for head and neck cancer. A large number of respodents did not answer the questions , which suggests patients' lack of knowledge or their denial of the harmfulness of the above-mentioned addictions. Conclusions. The majority of respondents were aware of the harmfulness of smoking and its effect on the development of cancer. However, they were not aware of the impact of drinking alcohol on the development of cancer. Most of the subjects knew what HPV is. However, the majority of respondents did not know that HPV belongs to oncogenic viruses. Smoking cigarettes differentiated their awareness of the impact of smoking on the development of cancer.
Wstęp. Choroba nowotworowa to złożony proces patologiczny, który rozwija się w ludzkim organizmie, który niszcząc zdrowe komórki prowadzi progresywnie do znacznych ograniczeń w funkcjonowaniu oraz znacznych dolegliwości bólowych, czasem nieustępujących po lekach przeciwbólowych. Choroba nowotworowa narządów głowy i szyi w znaczny sposób obniża jakość życia w porównaniu do populacji osób zdrowych. Cel. Celem tego badania była ocena wiedzy pacjentów na temat czynników ryzyka związanych ze stylem życia, a występowaniem chorób nowotworowych głowy i szyi. Materiał i metody. Badanie przeprowadzono wśród 149 pacjentów, u których rozpoznano chorobę nowotworową głowy i szyi w Przyklinicznej Przychodni Centrum Onkologii w Gliwicach za zgodą tejże palcówki. W badaniu posłużono się autorska ankietą zawierającą w 38 pytań. Badanie realizowano od listopada 2016 r. do stycznia 2017r. Wyniki. Analiza wyników nie potwierdziła, że palenie wyrobów tytoniowych, picie alkoholu i wirus HPV są głównymi czynnikami ryzyka chorób nowotworowych głowy i szyi. Spora ilość zaznaczanych odpowiedzi to nie udzielenie odpowiedzi, co sugeruje o braku wiedzy pacjentów lub wyparcia przez nich szkodliwości w/w nałogów. Wnioski. Badani w zdecydowanej większości byli świadomi szkodliwości palenia papierosów i jego wpływu na powstanie choroby nowotworowej. Nie mieli natomiast świadomości wpływu picia alkoholu na rozwój choroby nowotworowej. Większość badanych wiedziała, czym jest wirus HPV. Natomiast badani w większości nie mieli wiedzy, że wirus HPV należy do onkogennych. Palenie papierosów kiedykolwiek przez badanych różnicowało ich świadomość wpływu palenia papierosów na powstanie choroby nowotworowej.

Opis:
Introduction: Malignant lymphoma (ML) is a neoplasm caused by clonal expansion of undifferentiated B, T and NK-lymphoid cells. WHO classification divides lymphomas into two main types, i.e. Hodgkin lymphoma (HL), and non-Hodgkin lymphoma (NHL), with numerous subtypes. The majority of MLs are localized in lymph nodes, but extranodal locations are also possible. MLs represent approximately 3-5% of all malignant neoplasms in Poland, but their incidence has been increasing in recent years, especially in young patients. The objective of the study was to evaluate clinical manifestations and diagnostic process in patients with malignant lymphomas of the head and neck region as diagnosed in the Department of Otorhinolaryngology of the Medical University of Lodz in years 2013-2017. Material and method: 30 patients diagnosed with malignant lymphomas of the head and neck region at the Departbadament of Otorhinolaryngology of the Medical University of Lodz in 2013-2017. Results: The study group consisted of 8 cases of nodal lymphomas and 22 cases of extranodal lymphomas. In 29 cases B-cell lymphomas were diagnosed. The most common symptoms included lymphadenopathy or neck tumor. Other symptoms were associated with the location of tumors in particular body organs. The diagnosis was based on histopathological examination of biopsy (needle or surgical) samples. Conclusion: Malignant lymphomas should be taken into account during differential diagnosis of the tumor or lymphadenopathy of the neck. The diagnosis is difficult because of the nonspecificity of symptoms and the need for interdisciplinary cooperation of many specialists.

Introduction: Head and neck squamous cell carcinoma (HNSCC) accounts for about 6% of all malignant cancers. In the epidemiology of oral cavity neoplasm, important risk factors include: tobacco smoking, alcohol abuse, bad oral hygiene, papilloma virus infection, riboflavin and iron deficiency. Objective: The objective of the investigation was a synthesis of Cu(II) complex and the evaluation of antioxidative enzymatic barrier in red blood cells of patients with head and neck tumor as well as in the control group. Materials and methods: For the investigation conduction, a consent of Bioethics Committee number RNN/142/09/KB was obtained. Blood for the examination was obtained from the patients of the Dapartment of Head and Neck Neoplasms Surgery Medical University of Łódź. The experiment was conducted on the group of 40 patients with HNSCC and 40 healthy people, using spectrophotometric method, glutathione peroxidase was marked. Results: The investigation was conducted on the hemolysate obtained from the patients that were divided into two groups – a study group (1 and 2), which consisted of patients diagnosed with head and neck cancer and a control group (1 and 2) – healthy people. A significant statistical result for GPX occurred in control-1 and study-1 group with complex compound Cu(II) (p<0,001). Conclusions: Presented research prove, that complex compound Cis-dichlorobis(N1-hydroxymethyl-3methylpyrazole-κN2)copper (II) has an impact on the activity of the antioxidative GPX enzyme.

Opis:
Elective tracheostomy before resection of a malignancy in head and neck region assures unobstructed ventilation during postoperative period but is associated with an increased risk of complications. We aimed to evaluate retrospectively, how the application of elective tracheostomy scales would influence the frequency of tracheostomy in comparison with preoperative clinical judgement. In 205 patients operated on from 2013 till 2017, theresection of a malignancy involved suprahyoid or pharyngeal muscles, neck dissection and flap reconstruction. The decision on elective tracheostomy was made on the clinical basis. Score for each patient in 3 published scales was calculated. In the study group 76 patients had elective tracheostomy at the outset of a resection procedure. Among 129 patients without elective tracheostomy, 9 had tracheostomy in the postoperative period. Indications for elective tracheostomy were calculated for scale I, II and III. Only in 120 patients the decision whether to perform elective tracheostomy would be identical in each scale. Our results suggest that decisions to perform elective tracheostomy based on 3 scales show low specificity. The factors used in the published scales should be evaluated in a prospective multicenter study

Introduction: Microvascular free tissue transfer enables the reconstruction of complex head and neck defects. The aim of the study was to assess the results of treatment of patients undergoing reconstructive surgery and to identify factors affecting these results, with particular reference to patient’s age. Materials and Methods: All patients who underwent free-flap head and neck reconstruction in our institution between 2010 and 2017 were included in this retrospective study. A series of 66 patients met the inclusion criteria and were divided into 2 age groups: group G1 aged <65 years (n = 41) and group G2 aged ≥65 years (n = 25). Minor local complications and general complications as well as comorbidities were analyzed. Results: No correlation was found between advanced age and the risk of free flap failure as well as the incidence of local minor complications. General complications were more frequent in the G2 group (32%) than in the G1 group (19.5%), although this is not a statistically significant difference. A statistically significant difference was found between the age and the patient’s health status according to ASA (P = 0.010). In the younger low-risk group, 12 patients (29.3%) had general and local complications, while in the older low-risk group only 1 (4%). General and local complications were found in 5 (12.2%) high-risk G1 patients and in 7 (28%) high-risk G2 patients. Conclusion(s): Patients with advanced head and neck malignant tumors should undergo reconstructive microsurgery regardless of age.

Opis:
Introduction: Radiotherapy (RT) for patients with head and neck squamous cell carcinoma (HNSCC) affects vital functions related to the irradiation volume of the head and neck region and, in addition, has a negative impact on social functioning, thereby significantly impairing patients’ quality of life (QoL). Aim: The aim of this study was to assess changes in the quality of life in patients with head and neck cancer treated with curative RT at 12 months after completion of RT. The aim of this study was to assess the differences between the baseline QoL of patients with early clinical stage HNSCC and at 12 months after curative/radical RT. Material and methods: The prospective clinical study included 92 patients in good general condition (ECOG 0–1 – Eastern Cooperative Oncology Group performance status), without regional or distant metastases, diagnosed with pathomorphologically confirmed early-stage head and neck squamous cell carcinoma treated with definitive RT. All patients participating in the study signed an informed consent form. QoL was assessed using the standard EORTC QLQ-C30 and QLQH&N35 questionnaires. In addition, information on clinical aspects and data relating to socio-demographic factors were obtained from each patient. Statistical analysis was performed using a statistical package (SPSS 17.0). T-test was used for dependent and independent samples. A general linear model was used for repeated measures. Results: Patients’ QoL deteriorated significantly after definitive RT. Worse QoL Core-30 scores in patients 12 months after the end of RT, compared with baseline QoL, before the start of RT, were observed in domains such as physical performance, fulfillment of life roles, cognitive functioning, loss of appetite, fatigue and constipation. For the QLQ-H&N35 questionnaires, patients 12 months after the end of RT reported problems in relation to aspects of life such as senses, mouth opening, dry mouth, thick saliva, pain, and weight loss. Conclusion: RT, even in early clinical stage head and neck cancer, has a negative impact on QoL, despite modern treatment techniques.

Opis:
Exosomes are membrane vesicles of endocytic origin that participate in inter-cellular communication. Environmental and physiological conditions affect composition of secreted exosomes, their abundance and potential influence on recipient cells. Here, we analyzed protein component of exosomes released in vitro from cells exposed to ionizing radiation (2Gy dose) and compared their content with composition of exosomes released from control not irradiated cells. Exosomes secreted from FaDu cells originating from human squamous head and neck cell carcinoma were analyzed using LC-MS/MS approach. We have found that exposure to ionizing radiation resulted in gross changes in exosomal cargo. There were 217 proteins identified in exosomes from control cells and 384 proteins identified in exosomes from irradiated cells, including 148 "common" proteins, 236 proteins detected specifically after irradiation and 69 proteins not detected after irradiation. Among proteins specifically overrepresented in exosomes from irradiated cells were those involved in transcription, translation, protein turnover, cell division and cell signaling. This indicated that exosomal cargo reflected radiation-induced changes in cellular processes like transient suppression of transcription and translation or stress-induced signaling.

Opis:
CBCT is a relatively new diagnostic imaging method. It was first used in 1982 at the Mayo Clinic Biodynamics Research Laboratory [1], and has been commercially used in dentistry since 2001. It differs from multidetector computed tomography in terms of implementation technique and some parameters. A low dose of radiation is its greatest advantage, thanks to which many specialists, including ENT doctors and reconstructive surgeons, are more willing to use it. In otorhinolaryngology, CBCT is applied in pre- and perioperative diagnostics in both rhinology and otology. In reconstructive surgery, CBCT facilitates precise planning of the flap and intraoperatively allows a perfect match of the reconstructed tissue elements. In the article, the authors present current information on CBCT in ENT obtained on the basis of a review of Polish and foreign literature and share their own experience in its application in reconstructive surgery within the craniofacial region.

Introduction: The nose is the central and probably the most important organ of the face. In view of the three-dimensional shape and variety of tissues, reconstructive surgery after tumor resection in this anatomical region requires the surgeon’s knowledge of anatomy. Materials and Method: In the years 2010–2019, 48 patients were treated in the Oncological and Reconstructive Surgery Clinic for extended nasal tumors, which required the use of free microvascular flaps after resection for functional and aesthetic supply of anatomical structures of the nose. Results: In 48 patients, a total of 92 free microvascular flaps were used for nasal reconstruction including: radial forearm free flap in 24 patients, radial forearm free flap with radial bone in 14 patients, auricular free flap in 16 patients, radial forearm free flap in combination with auricle free flap in 7 patients, double auricular free flap in 6 patients, radial forearm free flap in combination with double auricular free flap in 4 patients. Total necrosis of the free flap was noted in 4 cases, partial in 6 patients. Conclusions: The presented surgical techniques using microvascular free flaps constitute a recognized method of treatment and should be used in everyday surgeon practice. The results demonstrated in this article allow to obtain optimal functional and aesthetic effects.

Opis:
The aim of this study was to evaluate the effect of niclosamide, an antihelminthic drug recently identified as potential anti-cancer agent, on head and neck squamous carcinoma cells (HNSCC) viability, cell cycle distribution and apoptosis. The expression of key components of Wnt (CTNNB1, GSK-3β, CCND1, c-MYC, MMP7, BIRC5, Axin2) and glycolysis (GLUT1, MCT1, HK2, PFKM, PKM2, PDHA1, PDK1, LDHA) pathways was also examined to assess possible involvement in niclosamide anti-carcinogenic activity. HNSCC cells (FaDu, BICR6, H314 lines) were used in the research. Niclosamide treatment affected hypopharyngeal FaDu cells to the most extent (IC50 = 0.40 µM), while H314 cells derived from the floor of mouth were the least sensitive (IC50 = 0.94 µM). In FaDu cells the increased percentage of the cells in the S phase was observed along with the induction of apoptosis. Treatment with niclosamide in FaDu cells reduced the expression of MMP7 and the majority of glycolytic genes except increased LDHA. These results indicate that niclosamide is efficient inhibitor of HNSCC cells viability, however this effect depends on the cell type. In FaDu cells, the most sensitive to its anti-proliferative effect and prone to cell cycle arrest and apoptosis, this effect might be related to slightly modulation of canonical Wnt signaling and increased expression of LDHA.

Opis:
Advanced head and neck squamous cell cancers (HNSCC) have unfavorable prognosis and new therapeutic options are necessary to improve treatment outcomes. The Wnt pathway plays an important role in the pathogenesis and progression of HNSCC. The aim of this study was to assess the effects of a histone deacetylase inhibitor – panobinostat on Wnt-dependent gene expression and on cell migration. Cell viability in HNSCC cell lines (BICR6, CAL27, FaDu, H314, SCC-25) was evaluated by MTT assay. The expression of β-catenin-target genes was assessed by qPCR and TCF/LEF-dependent reporter assay. Protein content was evaluated by Western blot. Cell migration was analyzed by the wound healing assay. Panobinostat showed differential modulation of gene expression. It reduced the level of Axin2 in CAL27 and SCC-25 cells but upregulated its expression in BICR6 and H314 cell lines. Moreover, it diminished the expression of MMP7 in BICR6, H314 and CAL27 cell lines. In contrast, the inhibitor of β-catenin transcriptional activity – PKF118-310 down-regulated the expression of β-catenin-target genes in HNSCC cell lines. Interestingly, panobinostat had opposite effects on cell migration in CAL27 and FaDu where it inhibited or stimulated migration, respectively. On the other hand, PKF118-310 reduced cell migration. The anti-cancer effects of panobinostat in HNSCC cells are rather not related to the inhibition of Wnt signaling. PKF118-310 attenuates Wnt signaling, but only in a limited number of HNSCC cell lines. Importantly, the inhibition of Wnt pathway reduces the capacity of cells for migration suggesting that it may potentially therapeutically reduce cell invasion.
