Opis:: Objectives Head and neck cancer (HNC) is one of the most common cancers. Most exogenous HNC is head and neck squamous cell carcinomas. Scientists are striving to develop diagnostic tests that will allow the prognosis of HNC. The aim of the study was to determine the risk of HNC. The research concerned changes caused by polymorphisms in genes encoding proteins responsible for the metabolism of xenobiotics. Material and Methods In group of 280 patients with HNC, the occurrence of polymorphic variants in NAT1(rs72554606), NAT2(rs1799930), CYP1A(rs1799814), CYP2D(rs3892097) were studied with TaqMan technique. The control group consisted of 260 cancer free people. The TNM scale was analyzed. Gene interactions of genotyped polymorphisms were investigated. The effects of smoking and alcohol consumption on HNC were assessed. Results The results indicated an increased risk of HNC in NAT1 polymorphisms in the GC genotype (OR = 1.772, 95% CI: 1.184–2.651, p = 0.005) and NAT2 polymorphism in the GA genotype (OR = 1.506, 95% CI: 1.023–2.216, p = 0.037). The protective phenomenon in the CYP1A polymorphism the GT genotype (OR = 0.587, 95% CI: 0.381–0.903, p = 0.015) and the TT genotype (OR = 0.268, 95% CI: 0.159–0.452, p = 0.001). The coexistence of GA-GC polymorphisms (OR = 2.687, 95% CI: 1.387–5.205, p = 0.003) in NAT2-NAT1 genes increases the risk of HNC. Risk-reducing effect in the polymorphism GG-GT (OR = 0.340, 95% CI: 0.149–0.800, p = 0.011), GG-TT (OR = 0.077, 95% CI: 0.028–0.215, p < 0.0001), GA-TT (OR = 0.250, 95% CI: 0.100–0.622, p = 0.002), AA-GT (OR = 0.276, 95% CI: 0.112–0.676, p = 0.002) in NAT2-CYP1A genes. In the CYP2D-CYP1A genes in the polymorphisms CT-CC (OR = 0.338, 95% CI: 0.132–0.870, p = 0.020), TT-GG (OR = 0.100, 95% CI: 0.027–0.359, p = 0.001), TT-GC (OR = 0.190, 95% CI: 0.072–0.502, p = 0.0004), TT-CC (OR = 0.305, 95% CI: 0.107–0.868, p = 0.024). Correlation was noted between cigarette smoking and HNC (OR = 7.297, 95% CI: 4.989–10.674, p < 0.0001) and consuming alcohol (OR = 1.572, 95% CI: 1.003–2.464, p = 0.047). Conclusions The CYP1A polymorphism shows a protective association with HNC. On the other hand, NAT2, NAT1 polymorphism influence the susceptibility to developing HNC. The coexistence of the NAT2-NAT1 genotypes increases the risk of HNC. In contrast, NAT1-CYP1A and CYP1A-CYP2D reduce this risk. Smoking and alcohol consumption increase the incidence of HNC.

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

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:: Introduction: The aim of the study was to prove that a combination of visual surgical planning (VSP) and cone beam computed tomography (CBCT) is an optimal technique in fibular free flap reconstructions after complex tumor resections in the head and neck region and that it leads to better functional and aesthetic outcomes. Material and method: Six patients (3 females, 3 males) with head and neck tumors were included in the study. The region concerned midface in 2 cases and mandible in 4 patients. On the basis of computed tomography of the head, fibular free flap (FFF) reconstruction was planned with the VSP technique. The 3D-printed models were prepared. At the beginning of the operation and a few minutes after the reconstruction, an xCAT CBCT by XORAN was performed. Minor corrections of the angles of the reconstructed bony parts were made where needed. The time of the operation was assessed for each case. Functional and cosmetic results were evaluated in a 1-year follow-up. Results: The mean time of operation was 6 hours and 48 minutes, which was approximately 1hour and 40 minutes less than standard reconstructive surgery. Functional recovery was achieved in all patients. Aesthetic result was unsatisfactory for 2 patients due to insufficient soft tissue masses of FFF. Conclusions: The authors claim that intraoperative CBCT imaging, regardless of the cost, improves the accuracy of aesthetic outcome of reconstructive surgeries based on VSP, especially in the region of the midface and the mandible. Further studies on a higher number of subjects are required.

Opis:: Background: Head and neck neoplasms stand for 6% of all malignant neoplasms worldwide. Chemotherapy has limited use due to the biological properties of the tumor (in the majority of cases moderately and poorly differentiated squamous cell carcinoma). The fundamental molecule used in treatment is cisplatin and its derivates, that can be associated with fluorouracil. The new chemotherapeutic agents are not in common use during the treatment of head and neck malignancies. However, the use of low molecular weight complexes Pd (II) carries the potential of being more effective in therapy. Material and Methods: Fifty-one patients, 30 men and 21 women (aged 52.9 ± 12.1 years) with head and neck cancer were included in the study. Fifty-one healthy subjects, 31 men and 20 women, (aged 54.1 ± 14.7 years) years formed the control group. Antioxidant enzymes, superoxide dismutase, and catalase activities in erythrocytes were examined. Results: An increased level of antioxidant enzymes was seen in the blood samples from patients with head and neck cancer after incubation with Pd (II) complex. In the group we obtained a statistically significant result p = <0.001. Discussion: That project may contribute to the development of new, more efficient head and neck cancer treatment strategies. In our opinion, the results can be used in the future to develop a valuable prognostic marker of the disease. This is important because the initial phase of cancer is asymptomatic. The search for factors involved in pathogenesis translates into economic benefits and makes therapy more effectiveness through the reduction of treatment expenses.

Opis:: Berberine (BBR) an active natural plant alkaloid extracted from Coptidis rhizoma, displays potent anticancer activity over a variety of cancer cell lines. The cytotoxic activity of BBR in cancer cells is attributed to persuade, programmed cell death characterized by the release of cytochrome c, accompanied by activation of caspase-3 and caspase-9. In the present study, we evaluated BBR significantly reduces the cell viability and clonogenic property of head and neck squamous carcinoma (HNSC) cells. Our results revealed that BBR simultaneously induces apoptosis and autophagy in HNSC cells. Mechanistically, BBR induces autophagy in HNSC cells which were confirmed by acridine orange (AO) staining by visualization of prominent orange red color acidic autophagosomes in the cytoplasm. However, immunoblotting shows the steady conversion of MAP-LC-3I to LC-3II with concomitant degradation of autophagy substrate protein SQSTM1/p62. Annexin V FITC staining analysis by flow cytometry revealed a significant induction of apoptosis at higher doses of BBR. Furthermore, the immunoblotting analysis revealed a prominent cleavage of proapoptotic proteins procaspase-3 and PARP1 at higher doses of BBR. Additionally, we found significant upregulation and downregulation of tumor suppressor microRNA-155 (miR-155) and oncogenic miR-21 respectively, when HNSC cells were exposed to higher doses of BBR. In conclusion, these results demonstrate that BBR exhibits a significant anti-proliferative effect with the simultaneous induction of autophagy and apoptosis and modulates miRNA expression in HNSC cells.

Opis:: Background: Amyloidosis is a group of diseases caused by the extracellular accumulation of insoluble fibers called amyloid in the tissues and organs. They have a secondary beta-sheet structure, which makes them resistant to proteolysis. In histological examination amyloid deposits stain with Congo red and show an apple-green birefringence in polarized light. Amyloid deposits disturb the function of organs and cause clinical symptoms. Their formation or accumulation in the system may be acquired or inherited. Due to the location of amyloid deposits we distinguish systemic and localized amyloidosis with the formation of tumors (usually from light chains). Case reports: 5 cases of amyloidosis in the head and neck region are presented in this paper. The locations of the amyloid deposits were as follows: larynx, nasopharynx, sublingual and submandibular gland and the tongue. The initial clinical presentation correlated with location of amyloid tumour in our patients. Two patients had history of local recurrence of the disease. Surgical resection and histopathological examination were performed. Sections stained with Congo red confirmed the diagnosis of amyloidosis. Three patients had potential conditions predisposing to amyloidosis: previous radiotherapy, chronic inflammation due to hepatitis C virus infection and graft versus host disease. Conclusion: Amyloidosis should be considered as the cause of symptoms in pathologies of the head and neck region. The diagnosis requires a histopathological examination. The systemic form of the disease must be ruled out in all patients with head and neck amyloidosis. In localized amyloidosis the surgical resection of the lesions is the procedure of choice, however the organ’s functionality should be taken into account.
Podstawy naukowe: Amyloidoza, czyli skrobawica, to grupa chorób, których wspólną cechą jest pozakomórkowe gromadzenie się w tkankach i narządach nierozpuszczalnych białek o budowie włókienkowej, zwanych amyloidem. Mają one drugorzędową strukturę β-kartki, co czyni je opornymi na proteolizę. W skrawkach histologicznych złogi amyloidu wybarwiają się czerwienią Kongo i wykazują zielone świecenie w świetle spolaryzowanym. Depozyty amyloidu zaburzają funkcje narządów i powodują objawy kliniczne. Ich powstawanie lub gromadzenie się w ustroju może być stanem nabytym lub dziedzicznym. Ze względu na lokalizację złogów amyloidu rozróżniamy: (1) amyloidozę układową, czyli uogólnioną, oraz (2) miejscową z tworzeniem guzów (najczęściej z łańcuchów lekkich immunoglobulin). Opisy przypadków: W niniejszej pracy opisano 5 przypadków amyloidozy w regionie głowy i szyi. Zmiany zlokalizowane były w obrębie: krtani, nosogardła, ślinianki podjęzykowej i podżuchwowej oraz języka. Pacjenci zgłaszali objawy typowe dla procesu rozrostowego obejmującego wymienione narządy. U dwóch osób choroba miała charakter nawrotowy. Zmiany usunięto operacyjnie. Na podstawie badania histopatologicznego pobranych tkanek i charakterystycznego barwienie czerwienią Kongo i Saturna, rozpoznano obecność złogów amyloidu. U trzech pacjentów występowały stany predysponujące do wystąpienia amyloidozy: uprzednia radioterapia, przewlekły stan zapalny związany z zakażeniem wirusem zapalenia wątroby typu C i choroba przeszczep przeciwko gospodarzowi. U chorego z makroglosją rozpoznano postać uogólnioną amyloidozy. Podsumowanie: Amyloidoza może imitować objawy zmian rozrostowych w rejonie głowy i szyi. Jej rozpoznanie wymaga badania histopatologicznego. U każdego chorego z miejscową amyloidozą musi zostać wykluczona postać uogólniona. W przypadku postaci miejscowej, resekcja chirurgiczna zmian jest postępowaniem z wyboru. Należy wziąć pod uwagę zachowanie funkcjonalności narządu.

Opis:: 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:: 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.

Opis:: 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:: Currently, 3D printing in medicine does not comprise only prostheses or implants, but also medical modelling and surgical planning. The future of 3D printing is printing combined with tissue bioengineering (bioprinting). Scaffolds made in 3D technology containing living cells are a step to creating tissues and organs. Three-dimensional printing in surgery is now considered the future of reconstructive and regenerative medicine. Head and neck surgery also benefits from advances in 3D printing. In this article, we will describe some of the possibilities offered by 3D printing in the aspect of education, training, and printed prostheses for the needs of head and neck surgery.
Obecnie druk 3D w medycynie oznacza nie tylko protezy czy implanty, ale także modelowanie medyczne i planowanie chirurgiczne. Przyszłością będzie druk 3D połączony z bioinżynierią tkankową (bioprinting). Rusztowania wykonane w technologii 3D zawierające żywe komórki są krokiem do tworzenia tkanek i narządów. Druk trójwymiarowy w chirurgii uważany jest obecnie za przyszłość medycyny rekonstrukcyjnej i regeneracyjnej, a z dokonań na tym polu korzysta także chirurgia głowy i szyi. W prezentowanym artykule opiszemy niektóre możliwości, jakie daje druk 3D w aspekcie edukacji, szkoleń oraz drukowanych protez na potrzeby chirurgii głowy i szyi.

Opis:: Nowotwory regionu głowy i szyi to zmiany chorobowe w obrębie kompleksu ustno-twarzowego. Strukturalne i czynnościowe zaburzenia poszczególnych narządów orogardła powodują trudności w oddychaniu, połykaniu i w wymowie. Celem artykułu jest omówienie zaburzeń mowy u pacjentów onkologicznych regionu głowy i szyi po radykalnych operacjach chirurgiczno-rekonstrukcyjnych. Rodzaj zaburzeń językowych zależy od zaawansowania choroby nowotworowej, zakresu ubytku pooperacyjnego oraz indywidualnych umiejętności kompensacyjnych pacjenta. Największe odchylenia od normy występują w trakcie realizacji głosek [k, g, l, r], natomiast najsłabsze podczas fonacji samogłosek. Nadrzędnym celem logopedycznego postępowania terapeutycznego jest usprawnienie połykania, artykulacji i fonacji oraz umiejętności komunikacyjnych chorego z otoczeniem. Reedukacja czynności prymarnych i sekundarnych pacjenta onkologicznego po przebytym zabiegu rekonstrukcyjnym w obrębie twarzoczaszki sprawia, że współczesna logopedia jest integralną częścią leczenia onkologicznego.
Tumors of the head and neck region are lesions within the orofacial complex. Structural and functional disturbances of individual oropharyngeal structures cause difficulties in breathing, swallowing and pronunciation. The aim of the article is to discuss speech disorders of the head and neck regions in oncological patients after radical reconstructive surgery. The type of a linguistic disorder depends on the severity of the neoplastic disease, the extent of the postoperative loss and individual patient compensation skills. The greatest deviations from the norm occur during the implementation of sounds such as [k, g, l] and the smallest happen during phonation of vowels. The primary aim of speech therapy is to improve such skills as swallowing, articulation, phonation and communication of the patient with the environment. Re-education of the primary and secondary functions in the case of oncological patients after reconstructive surgery in the craniofacial region makes modern speech therapy an integral part of the oncological treatment.

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.

Opis:: Introduction: The aim of the study was to analyze the risk factors for oral cavity and pharyngeal cancer in people examined under the Head and Neck Cancer Prophylaxis Program. Material and methods: The study was conducted in a total of 300 patients, including 186 women and 114 men, as part of the Head and Neck Cancer Prevention Program in 2014–2018. Before the laryngological examination, the patients completed a demographic and medical questionnaire regarding the risk factors of head and neck cancer, including education, reported disease symptoms, smoking addiction, number of cigarettes smoked daily, alcohol consumption, frequency of visits in a dental office, oral hygiene measures, number of sexual partners, oral sex, family medical history of head and neck cancer. Results: The subjects reported the following symptoms: hoarseness 43.33%, difficulty swallowing 21.33%, pain or mouth burning 20.33% and other symptoms were observed in 46.33%. The main dental symptoms were: bleeding from the gums during teeth brushing in 48.89%, dry mouth 45.56%. Currently 20.33% of respondents smoke, whereas 54% of patients smoked in the past. In the analyzed material, the majority (80%) consumed alcoholic beverages. 27.67% of respondents admitted having oral sex, including 24.73% of women and 32.46% of men. After performing the extended diagnostics, the tumor was found in 10% of the subjects. C onclusions: Statistical significance of differences was found: between hoarseness and alcohol consumption, both in women and in men, between hoarseness and smoking in women, between difficulty in swallowing and smoking in women, between burning/pain in the mouth and smoking in men, between hoarseness and the cultivation of oral sex in men, between the difficulty of swallowing and the practice of oral sex in the studied men and between burning/pain in the oral cavity and the occurrence of malignancy.
