RESUMEN
METHODS: The study was a prospective, double-blind, placebo-controlled trial with patients diagnosed with LAR to HDMs and with concomitant asthma who underwent a 12-month treatment course of SLIT for HDM allergies. Seventeen patients were randomized to SLIT with the use of allergen extracts of D. pteronyssinus and D. farinae (50/50%) in SQ-HDM SLIT tablets and 15 patients were randomized to the placebo group. The total rhinitis score (TRSS), total asthma symptom score (TASS), combined total symptom score (TSS), total medication score (TMS), and FEV1 were analyzed.Results: In the final analysis, 16 patients who received SLIT and 14 who received placebo who completed the study protocol were included. Significant reductions in TRSS, TASS, TSS, and TMS after 12 months of treatment were observed in patients after SLIT (p < 0.05). A significant increase in the mean FEV1 between baseline and after 12 months of therapy was observed in the study, with p = 0.03 in the study group. Conclusion: SLIT can improve nasal and bronchial symptoms and reduce symptomatic treatment in patients with LAR and asthma and with hyperresponsiveness to HDMs.

Background and objectives: Facial weakness is the most important complication of parotid gland tumor surgery. The aims of this study are as follows: (1) assessment of the prevalence of postparotidectomy facial nerve dysfunction; (2) clinical and electrophysiological assessment of the facial nerve function before parotidectomy and at 1 and 6 months postoperatively; (3) assessment of the association of postoperative facial palsy with selected risk factors; and (4) assessment of the correlation between the results of clinical and neurophysiological assessments of facial nerve function. Materials and Methods: This study comprised 50 patients (aged 24-75 years) who underwent parotidectomy at the Department of Otolaryngology and Laryngological Oncology in Zabrze, Poland between 2015 and 2017. The evaluation included neurological, clinical and electrophysiological assessments of the facial nerve prior to surgery and at 1 and 6 months postoperatively. Results: No facial palsy was found preoperatively or 6 months postoperatively. Facial nerve dysfunction was found in 74% of patients 1 month postoperatively. In most cases (54%), paresis was mild or moderate (House-Brackmann grades II and III). The results of electrophysiological tests before parotidectomy were either normal or showed some mild abnormalities. We found a statistically significant correlation between the clinical assessment of the facial nerve function (based on the House-Brackmann scale) one month postoperatively and the latency of the CMAP response from the orbicularis oculi and orbicularis oris muscles. In all three studies, a statistically significant correlation was found between the amplitude of the compound muscle action potential (CMAP) of the orbicularis oris muscle and the degree of facial nerve weakness. Conclusions: The factors that may influence the risk of postoperative facial nerve paralysis (prolonged surgical time and the size and location of the tumor other than in the superficial lobe only) may indirectly suggest that surgery-related difficulties and/or surgeon experience could be crucial to surgery safety.

BACKGROUND This retrospective study from a single center in Poland aimed to identify factors associated with outcomes following salvage surgery in 50 patients with recurrent laryngeal cancer. MATERIAL AND METHODS The study group consisted of 50 patients with recurrent laryngeal cancer after primary organ preservation treatment (12 patients after partial surgery, 30 patients after radiation therapy, and 8 patients after prior treatment using both methods). None of the patients received chemotherapy before salvage surgery. All patients with recurrence of laryngeal cancer underwent total laryngectomy with elective bilateral nodal surgery. Local and/or nodal recurrence was considered the failure of primary organ preservation treatment. Efficacy of treatment was assessed in relation to overall survival (OS), disease-free survival (DFS), local control (LC), and locoregional control (LRC). RESULTS Treatment results showed a poor prognosis in patients with local and/or nodal recurrence of laryngeal cancer. In the study group, the updated 5-year rates were as follows: OS rate of 26%; DFS rate of 25%; LC rate of 44%; and LRC rate of 39%. Univariate analysis showed that the stage before primary treatment was a predictive factor of OS (P=0.012). CONCLUSIONS The findings from this retrospective study of 50 patients with recurrent laryngeal carcinoma showed that salvage surgery following organ preservation treatment resulted in a 5-year OS rate of 26%.

INTRODUCTION: Chronic rhinosinusitis (CRS) is one of the commonest chronic diseases. It is a systemic disease caused by many factors, including bacterial infections. There are two main types of CRS phenotypes: with polyps (CRSwNP) and without polyps (CRSsNP). AIM: Analysis of sinus mucosal microbiome in patients with CRS depending on the phenotype. Investigating a possible link between the type of bacterial flora and the coexistence of diseases present in the CRS (asthma, allergy or hypersensitivity to non-steroidal anti-inflammatory drugs (NSAIDs) as well as the number of performed operations. MATERIAL AND METHODS: The authors conducted a retrospective study of the bacterial flora of the nasal cavity in patients with CRS operated endoscopically from March 2016 to June 2017. The study consisted od 222 women and 248 men. On the basis of an endoscopic examination, patients were qualified for the phenotype with or without polyps. Based on the medical interview patients were divided into group with asthma, allergy, NSAID hypersensitivity, first and repeated operations. The statistical analysis was made. RESULTS: There is no statistically significant relationship (p = 0.8519) between the CRS penotypes. In the group with CRSsNP, a statistically significant relationship was found between the observed flora and the coexistence of asthma (p = 0.0409), a trend towards significance was also noticed in the case of allergy (p = 0.0947). There was no relationship between the flora and NSAID hypersensitivity (p = 0.7356). In the group of CRSwNP patients, no statistically significant relationship was found between the observed bacterial flora and the presence of asthma (p = 0.7393), hypersensitivity to drugs (p = 0.1509) or allergy (p = 0.7427). There is no statistical significance between the occurrence of particular flora and the multiplicity of operations in both the CRSwNP (p = 0.4609) and CRSsNP phenotypes (p = 0.2469). CONCLUSIONS: Gram-positive cocci were equally common in CRSwNP and CRSsNP. In the CRSsNP, there was a correlation between the coexistence of asthma and allergy, and the presence of Gram-positive cocci. There was no statistical significance between the occurrence of particular flora and the multiplicity of operations in both CRS phenotypes.
RESUMEN
The aim of this paper is to present our results and experience in the treatment of snoring using the non-ablative Erbium: Yttrium Aluminum Garnet (Er:YAG) laser. Twenty-four patients (18 male and 6 female) with snoring problems due to soft palate hypertrophy were treated with 3 treatment procedures with Er:YAG 2940-nm laser (long pulse mode, 10 Hz, fluence 1.8-2.0 J/cm2) performed at 2-week intervals. The treatment procedures were performed in outpatient settings. One treatment session lasts 15-20 min. Subjective (questionnaires) and objective (polygraph) outcome measures were assessed at baseline and 3 months after the final laser treatment. Wilcoxon Signed Rank was used to compare before and after scores. All polygraph variables showed some improvement 3 months after the end of treatment; however, only the reduction of the number of hypopnea episodes per hour was statistically significant (p = 0.034). In 13/24 patients, snoring time accounted for less than 5% of the sleep time after the treatment compared to 6/24 patients at baseline. The questionnaire survey showed statistically significant improvement in the quality of sleep and life of the patients as well as their partners after Er:YAG treatment (p < 0.001). The assessment of daytime sleepiness using the Epworth scale also improved 3 months after the end of treatment (p = 0.010). Based on our observations, the treatment of snoring with the Er:YAG laser is an effective and non-invasive therapeutic method. Further studies with long-term follow-up and a control group are warranted to confirm the promising results obtained in case series.

BACKGROUND: Local allergic rhinitis (LAR) is found in some patients with typical symptoms but who have negative skin prick tests and negative IgE to aeroallergens while presenting with positive nasal provocation tests for proper allergens. Little information about the clinical characteristics and prevalence of LAR has been published. The aim of this study was to determine the prevalence and characteristics of LAR in patients with symptoms of chronic rhinitis. METHODS: In total, 680 patients out of 3400 pre-screened subjects with chronic rhinitis who were at least 5 years old were included from 17 sites in Poland in the study protocol. The following medical history and diagnostic procedures were performed with aeroallergens: skin prick tests, allergen specific serum IgE and nasal provocation tests. In addition to LAR, allergic rhinitis (AR) and non-allergic (NAR) rhinitis were explored and compared. RESULTS: In total, 621 patients were examined. LAR was diagnosed in 109 (17.6%) patients; AR was diagnosed in 251 (40.4%) patients; and NAR was diagnosed in 261 (42%) patients. In the LAR group, younger, non-smoker patients with allergies to D. pteronyssinus or grass pollen were predominant. Polysensitization was more prevalent in AR patients than in LAR patients. Bronchial asthma was at a similar level in patients diagnosed with AR (38%) and LAR (35%) but was significantly less prevalent in patients diagnosed with NAR (16%). The mean age of disease onset was similar between patients with AR and LAR (17.6 plus or minus 4.8 yrs), and it was significantly lower than that in patients with NAR (24.5 plus or minus 6.9 yrs, p less than 0.05). CONCLUSIONS: LAR is a significantly understudied problem in patients of various ages with chronic nasal symptoms. Patients with LAR and AR have similar clinical phenotypes.

BACKGROUND A number of studies have documented the influence of cigarette smoking on hearing. However, the association between sex and hearing impairment in smokers as measured by otoacoustic emissions (OAEs) has not been clearly established. The aim of this study was to analyze sex-specific effects of smoking on hearing via conventional and ultra-high-frequency pure tone audiometry (PTA), and OAEs, specifically spontaneous OAEs, click-evoked OAEs, and distortion-product OAEs. MATERIAL AND METHODS The study included 84 healthy volunteers aged 25-45 years (mean 34), among them 46 women (25 non-smokers and 21 smokers) and 38 men (16 non-smokers and 22 smokers). The protocol of the study included otoscopic examination, tympanometry, low-, moderate-, and ultra-high-frequency PTA, evaluation of spontaneous click-evoked (CEAOEs) and distortion-product otoacoustic emissions (DPOAEs), assessment of the DP-grams for 2f1-f2 (f1 from 977 to5 164 Hz), and input/output function at L2 primary tone level of 40-70 dB SPL. RESULTS Smokers and non-smokers did not differ significantly in terms of their hearing thresholds assessed with tone audiometry. Male smokers presented with significantly lower levels of CEAOEs and DPOAEs than both male non-smokers and female smokers. CONCLUSIONS Smoking does not modulate a hearing threshold determined with PTA at low, moderate, and ultra-high frequencies, but causes a significant decrease in OAE levels. This effect was observed only in males, which implies that they are more susceptible to smoking-induced hearing impairment. Sex-specific differences in otoacoustic emissions level may reflect influences of genetic, hormonal, behavioral, and/or environmental factors.

AIM OF THE STUDY: Lymphomas are a heterogeneous group of tumours of lymphoid tissue in which there is an abnormal proliferation of cells of the lymphatic system. The literature notes a gradual increase in the incidence of this type of cancer in the whole population. The aim of the study was to evaluate whether the above tendency occurs in the head and neck area. MATERIAL AND METHODS: In the years 2005-2014, at the Otolaryngology and Laryngological Oncology Department of the Upper Silesian Medical Centre in Katowice, 77 cases of lymphoma were recorded, 58 of which were analysed in terms of location, histological type, age and sex of the patient, and the presence of risk factors. RESULTS: The vast majority of them were non-Hodgkin's lymphomas (NHL) - 67.53%. Hodgkin's lymphomas (HL) accounted for only a small fraction of diagnoses (7.79%). In terms of histopathological types, in most cases of NHL, there occurred diffuse large B-cell lymphomas (DLBCL) - 51.92%. The most common location was the lymph nodes, representing the location of the primary lesion in more than half of the cases. As regards the extranodal location, the Waldeyer ring dominated (54.54%) along with the palatal tonsil (40.90%). There has been a significant upward trend, especially in the incidence of NHL.
RESUMEN
BACKGROUND The aim of the study was to determine the prevalence of petrosquamosal sinus (PSS) and other temporal bone (TB) anatomical variations in various patients using high-resolution computed tomography (CT). MATERIAL AND METHODS We reviewed clinical and consecutively obtained CT data for 276 TBs of 138 patients. The incidence of TB anatomical variations was compared among patients with radiological markers of chronic otitis media (RCOM) and non-RCOM. RESULTS The PSS incidence in our sample was 6.9%, and it was significantly higher in TBs with RCOM (14.6%). Selected anatomical variations of RCOM TBs were observed: lateral sigmoid sinus (14.5%), prominent sigmoid sinus (23.6%), PSS (14.6%), and high jugular bulb (17.3%). Lateral sigmoid sinus and prominent sigmoid sinus (p<0.01), high jugular bulb (p<0.05), and PSS (p<0.01) were observed more often in RCOM than in non-RCOM TBs. CONCLUSIONS The TB vascular and anatomical variations, including PSS, a high jugular bulb, and a laterally and prominent placed sigmoid sinus, were more often observed in TBs with RCOM. Presurgical imaging and CT-based navigation techniques for TB surgery can offer remarkable value for understanding the altered anatomy of this complex structure and can localize rare anatomical variations.

BACKGROUND: Local allergic rhinitis (LAR) is characterized by the production of specific IgE in the nasal mucosa and a positive response to a nasal provocation test in the absence of atopy by conventional measurements. There is no information about LAR in elderly people, just as there is little information about allergic rhinitis (AR) in this age group. OBJECTIVE: To investigate the prevalence of LAR, AR, and non-AR in elderly patients with rhinitis. METHODS: In 219 patients with a mean (SD) age of 65.81 (5.88), skin prick tests, serum total specific IgE, and nasal provocation tests against common aeroallergens were performed. In addition, nasal specific IgE was measured in the nasal lavage at baseline and after provocation. For monitoring nasal symptoms, a visual analog scale was used. RESULTS: Of the 219 patients, 46 (21.0%) had LAR, 88 (40.2%) had AR, and 85 (38.8%) were diagnosed as having non-AR. Dermatophagoides pteronyssinus was the main sensitizing aeroallergen in patients with LAR (29 patients [63.0%]) and with AR (48 patients [56.4%]). No significant differences were found between the visual analog scale score and the type of AR (local or nonlocal) and the types of allergens. Clinical responses during the nasal provocation test were associated with significant increases in nasal IgE (Spearman correlation test, R = 0.89, P < .05). Polysensitization was more predominant in patients with AR than in those with LAR (P < .05). CONCLUSION: The results indicate that LAR and AR are common in elderly patients. However, in this age group, these conditions are often underdiagnosed.

INTRODUCTION: The complicated etiology of chronic sinusitis with polyps and frequent allergy to mould is established. AIM: We aimed to investigate the frequency of the IgE-dependent hypersensitivity in this group of patients and prove the need of surgery in allergic chronic rhinosinusitis patients. MATERIAL AND METHODS: Forty-two patients (19 females, 23 males) aged 34-73 years (55 ±12.6 years), with chronic sinusitis with polyps were included into the study. Functional endoscopic sinus surgery, laryngological examination, sinus computed tomography scans, and smear from maxillary sinus for microbiological examination were done in all patients. Skin prick tests with common perennial and seasonal inhalant allergens, tIgE and sIgE against moulds were required. RESULTS: Thirty-two of 42 patients (71.4%) were allergic to at least one inhalant allergen. A mean concentration of total IgE was 241.2 ±186.3 kU/l (35.0-708.0 kU/l) and was lower in patients with fungal culture found in sinus mucin than in patients without fungal presence 75.1 ±54.6 kU/l vs. 284.3 ±204.1 kU/l. We found no difference in the number of positive skin prick tests in a group with and without fungal culture. None of patients with fungal culture found in sinuses presented a detectable level of mold sIgE. All patients with fungal vegetation in sinuses required at least two polypectomy procedures. CONCLUSIONS: The total IgE concentration was significantly lower in patients with fungal presence in sinuses. Nasal polyps occurred more frequently in patients with fungal presence in sinuses.
RESUMEN
BACKGROUND: The DIAPH2 gene is one of the genes commonly associated with laryngeal squamous cell carcinoma (LSCC). In our study, we considered the four polymorphisms of this gene, i.e. rs5920828, rs4322175, rs12851931 and rs5921830 as potential genetic risk factors for LSCC. METHODS: We determined the genotyping of the genetic variants of DIAPH2 in 230 male patients with histologically confirmed LSCC compared to the European population. Demographic and environmental exposure data of each subject were examined. To conduct the genetic tests, extraction of total DNA was performed. We genotyped all four variants in each patient and determined their frequencies. RESULTS: In the case of the rs12851931 polymorphism in the DIAPH2 gene, a significant difference was observed in the distribution of the T stage depending on the polymorphism. Heterozygotes were more often associated with T2 stage, while homozygotes were more likely to have higher tumor stages. The rs12851931 homozygotes of DIAPH2 were statistically significantly more prevalent in smokers. The results suggested that rs12851931 polymorphism in DIAPH2 could increase the onset risk of LSCC. CONCLUSIONS: Our results provide further information on the role of the DIAPH2 gene in the pathogenesis of LSCC.

INTRODUCTION: Sleep is the physiological state of the body where proper morphology and duration are indispensable for human functions throughout both, physical and mental spheres. Disordered breathing during sleep impairs its morphology and results in major disorders in any age group. Adverse effects of Obstructive Sleep Apnea Syndrome in children and poor availability of centers offering children's polysomnography call for a reliable and easily accessible screening method. AIM: The aim of the study were to evaluate the usefulness of pulse transit time in the diagnostics of disordered sleep breathing in children and to attempt to employ the parameter in screening tests. Pulse transit time is a physiological parameter determining the time needed for the pulse wave to travel between two measurement points. MATERIAL AND METHODS: Enrolled in the retrospective study were 153 patients (100 boys and 53 girls) suspected of obstructive sleep apnea syndrome who underwent polysomnography at I. Moscicki ENT Hospital in Chorzów. RESULTS: Statistically significant relations between apnea/hypopnea index and pulse transit time were observed in both, individual age groups and all of the patients. Pulse transit time results proved a negative correlation with apnea/hypopnea index values commonly accepted as a parameter concluding the polysomnography procedures. CONCLUSIONS: The results of the study indicate that pulse transit time measurements may find application in screening tests of sleep-disordered breathing in children.

BACKGROUND: Actinomyces is a genus of Gram-positive anaerobic or microaerophilic bacteria with a branched filamentous shape. Their presence in tonsil tissue is usually determined by histopathological examination. In the crypts of removed tonsils, they have a prevalence ranging from 0.8% to 61.6%. The role of Actinomyces in diseases of the palatine tonsils is not clearly defined. The aim of the study was to determine the importance of Actinomyces in the pathology of palatine tonsils and to assess the impact of these bacteria on the clinical data. METHODS: the retrospective analysis of the histopathological findings of patients undergoing tonsillectomy in our hospital from January 2017 to the end of December 2019 was performed in terms of the occurrence of Actinomyces. The data were collected based on the medical history. The study included 481 patients aged 3-82 years. From the study group, 100 adult patients were randomly selected, and a telephone survey was conducted. The questions included the co-occurrence of bronchial asthma, halitosis, tonsilloliths, and cigarette smoking. The questions were related to the complications following tonsillectomy and the severity of postoperative pain. Existence of a relationship was investigated between occurrence of tonsillar Actinomyces and age, sex, body mass index, and medical condition (obstructive sleep apnea, chronic palatine tonsillitis), respectively. The size of the removed tonsils was assessed and compared depending on the presence of the bacteria. RESULTS: patients aged 18 years and older had a higher probability of presenting Actinomyces. The estimated odds ratio for the presence of the bacteria per year of age was 1.023 [1.007, 1.041]. No statistically significant results were found for the other variables. The co-occurrence of the bacteria and halitosis was close to statistical significance (p = 0.064). CONCLUSIONS: multivariate analysis of the role of Actinomyces in tonsillar pathology showed that these microorganisms should be considered saprophytes of the oropharyngeal microflora that had no significant relationship with the pathology of palatine tonsils. Further studies on their influence on halitosis are warranted.
RESUMEN
This study aimed to systematically review the literature to determine the efficacy and safety of transoral robotic surgery (TORS) in the management of submandibular gland (SMG) sialolithiasis. PubMed, Embase, and Cochrane were searched for English-language articles evaluating TORS in the management of SMG stones published up to 12 September 2022. Nine studies with a total of 99 patients were included. Eight patients underwent TORS followed by sialendoscopy (TS); 11 patients underwent sialendoscopy followed by TORS and sialendoscopy (STS); 4 patients underwent sialendoscopy followed by TORS only (ST); and 4 patients underwent TORS without sialendoscopy (T). The mean operative time amounted to 90.97 min. The mean procedure success rate reached 94.97%, with the highest for ST (100%) and T (100%), followed by the TS (95.04%) and STS (90.91%) variants. The mean follow-up time was 6.81 months. Transient lingual nerve injury occurred in 28 patients (28.3%) and was resolved in all of them within the mean of 1.25 months. No permanent lingual nerve injury was reported. TORS is a safe and effective management modality for hilar and intraparenchymal SMG sialoliths, with high procedural success in terms of successful sialolith removal, SMG preservation, and reduced risk of permanent postoperative lingual nerve damage.
RESUMEN
Objective: The study is a retrospective comparison of the usefulness of salvage surgery between a group of previously radiotherapy-treated patients (RTPs) and a group of patients who previously underwent partial surgery with both local and ± nodal recurrence. Study Design: Retrospective study. Setting: Multi-center academic hospital. Materials and Methods: The former group was comprised 30 previously RTPs, whereas the latter group consisted of 20 patients after partial laryngeal surgery with optional subsequent adjuvant radiotherapy (PSPs). Treatment efficacy was compared in both groups in relation to overall survival (OS) and the locoregional control rate (LCR). Local and ± nodal recurrence was considered primary treatment failure. All patients underwent total laryngectomy. Results: The updated 5-year OS in the PSPs was 31%, while the percentage of the updated 5-year LCR was 42%. In the RTPs the updated 5-year OS was 21%, and the percentage of 5-year LCR was 38%. No statistically significant differences were found in terms of the comparison of OS or the comparison of LCR results in both groups (P = 0.427, P = 0.704, respectively). Conclusions: Based on the analysis, it was found that irrespective of the initial treatment, salvage surgery was associated with decreased survival and cure rates (by 50%) compared to the group of patients with advanced laryngeal cancer who underwent primary total laryngectomy.

Objective: The aim of this study was to assess the long-term outcomes of nonablative Er:YAG laser treatment for snoring. Background data: Nonablative Er:YAG laser treatment has been shown to improve subjective quality of sleep without serious adverse effects, but long-term data are lacking. Materials and methods: Twenty-four patients with snoring problems due to soft palate hypertrophy were treated with three treatment procedures with Er:YAG laser performed at 2-week intervals. Subjective (questionnaires) and objective (polygraph) outcome measures were assessed at baseline, 3 months, and 4 years after the final laser treatment. Results: Twenty patients returned for the 4 years follow-up. The significant improvement in subjective sleep outcomes observed 3 months after Er:YAG laser treatment was still significant 4 years after treatment. No significant improvement or deterioration in objective polygraph outcome measures was observed during the 4 years of follow-up in our study. No side effects of laser treatment were observed. Conclusions: The Er:YAG laser treatment presents a safe and well-tolerated snoring treatment alternative for patients with airway obstruction in the oropharynx with improvement in subjective sleep outcomes lasting up to 4 years.

Recent studies identified viral and bacterial factors, including HSV-1 and H. pylori, as possible factors associated with diseases such as chronic tonsillitis and cancers, including head and neck squamous cell carcinoma (HNSCC). We assessed the prevalence of HSV-1/2 and H. pylori in patients with HNSCC, chronic tonsillitis, and healthy individuals using PCR after DNA isolation. Associations were sought between the presence of HSV-1, H. pylori, and clinicopathological and demographic characteristics and stimulant use. HSV-1 and H. pylori were most frequently identified in controls (HSV-1: 12.5% and H. pylori: 6.3%). There were 7 (7.8%) and 8 (8.6%) patients with positive HSV-1 in HNSCC and chronic tonsillitis patients, respectively, while the prevalence of H. pylori was 0/90 (0%) and 3/93 (3.2%), respectively. More cases of HSV-1 were observed in older individuals in the control group. All positive HSV-1 cases in the HNSCC group were associated with advanced tumor stage (T3/T4). The prevalence of HSV-1 and H. pylori was highest in the controls compared to HNSCC and chronic tonsillitis patients, which indicates that the pathogens were not risk factors. However, since all positive HSV-1 cases in the HNSCC group were observed only in patients with advanced tumor stage, we suggested a possible link between HSV-1 and tumor progression. Further follow-up of the study groups is planned.
RESUMEN
MiRNAs could play an important role in tumorigenesis and progression. The oncoprotein MDM2 (murine double minute 2) was identified as a negative regulator of the tumour suppressor p53. This study aims to analyse the expression of the MDM2 target miRNA candidates (miR-3613-3p, miR-371b-5p and miR-3658) and the MDM2 gene in oral squamous cell carcinoma tumour and margin samples and their association with the selected socio-demographic and clinicopathological characteristics. The study group consisted of 50 patients. The miRNAs and MDM2 gene expression levels were assessed by qPCR. The expression analysis of the miRNAs showed the expression of only one of them, i.e., miR-3613-3p. We found no statistically significant differences in the miR-3613-3p expression in tumour samples compared to the margin samples. When analysing the effect of smoking on miR-3613-3p expression, we demonstrated a statistically significant difference between smokers and non-smokers. In addition, we showed an association between the miR-3613-3p expression level and some clinical parameters in tumour samples (T, N and G). Our study demonstrates that miR-3613-3p overexpression is involved in the tumour progression of OSCC. This indicates that miR-3613-3p possesses potential prognostic values.

AIM: The aim of the study was to evaluate the results of partial laryngectomies in patients with laryngeal cancer treated in the 2(nd) Clinical Department of Laryngology SUM in Zabrze in the years 1990-2000. MATERIALS AND METHODS: Retrospective clinical material includes 209 patients in whom surgery was a primary treatment method. No distant metastases (M1) or another malignant cancer were found. The group consisted of 20 (10%) women and 189 (90%) men. The mean age was - 51.2 years. The stage of the neoplasm progression was defined as T1 in 91 patients (44%), T2 in 109 patients (52%). In other 9 patients (4%) the progression stage was T3 and T4. Clinical examination in 191 patients (91%) did not show enlarged lymph nodes in the area of head and neck (N0). In the group of remaining 18 patients (9%) the node progression was found to be N1-N3. In all 209 patients the squamous cell carcinoma of various stage of malignancy (G1-G3) was found in preoperative histopathological tests, out of which five cases were of papillary squamous cell carcinoma. The most common operation in the analyzed group was a chordectomy - 83 surgeries (40%), followed by 38 (18%) vertical partial laryngectomies, 28 (13%) horizontal glottis surgeries, 19 (9%) frontal-lateral and frontal-anterior operations, and supracricoid operations with a reconstruction of CHEP and CHP type, a total of 20 operations (9%). Other types of partial operations were performed less commonly. In 79 patients (38%) partial laryngectomy was complemented with a nodal operation, while cervical lymph nodes were not removed in 130 patients (62%). In 19 cases (9%) the metastases of squamous cell carcinoma to regional lymph nodes were confirmed in postoperative material. 82 patients of the study group (39%) underwent radiotherapy. The median of the observation period was 9 years. Local recurrence, nodal recurrence and distant metastasis are rated as treatment failure. Treatment effectiveness was evaluated with relation to local control, overall survival, disease-free survival and cause specific survival. All the aforementioned parameters were analyzed with the method of updated percentages. The level of statistical significance was assumed to be p ≤ 0.05. RESULTS: The updated 5-year and 10-year percentage of overall survivals was respectively 75% and 63%. The updated 5-year and 10-year percentage of cancer specific survivals was 85% and 79%, respectively. The updated 5-year and 10-year percentage of disease-free survivals was 72% and 56%, respectively. The percentage of 5-year and 10 year local controls was 86% and 79%, respectively.
