Molecular testing is recommended in patients with metastatic non-small cell lung cancer (NSCLC), but the extent of its use in Poland is unknown. The aim of the POL-MOL study was to investigate the frequency of using molecular testing in Polish patients with NSCLC. The invited Polish oncologists completed two questionnaires, and data for 1001 patients undergoing systemic treatment for NSCLC were collected. The use of molecular tests for the following genetic mutations was recorded: EGFR (del19, sub21), EGFR (other than del19/sub21), EGFR T790M, ALK (expression and rearrangement), RET, NTRK, ROS1, BRAF, HER2, and MET, as well as for immunochemical assessment of programmed cell death ligand 1 (PD-L1). Thanks to the weighting procedure, the results are representative of the population of Polish patients treated for NSCLC. Molecular tests were applied in 78% of patients with NSCL, 70% of patients with NSCLC not otherwise specified, and in 12% of patients with squamous cell carcinoma of the lung. The frequency of application increased with disease stage in all groups. In patients with squamous cell carcinoma, approximately 30% of tests for EGFR, ALK, and RET mutations were positive, which confirms the importance of testing at least a preselected subgroup of patients.

The study was conducted in the era when maintenance immunotherapy with durvalumab was not available in clinical practice after chemoradiotherapy (CRT) in unresectable non-small-cell lung cancer (NSCLC). The main aim of the study was to check whether the presence of cardiovascular diseases (CVD) and their pharmacotherapy affects the overall survival (OS) in such NSCLC patients undergoing sequential CRT. The group of 196 patients were analyzed: 101 patients with CVD (51.53%) and 95 patients with other reasons of qualification for sequential CRT (decreased performance status, older age, and other non-cardiovascular co-morbidities). Although patients with CVD were more often in older age, and they more often experienced cardiac and nephrological complications (p < 0.05 for all), there was a statistically nonsignificant trend for lower all-cause mortality in patients with CVD. The lowest all-cause mortality was observed in patients treated with beta-blockers and statins after two (HR = 0.31; 95%CI: 0.1–0.98; p = 0.047), three (HR = 0.33; 95%CI: 0.13–0.81; p = 0.015) and even four (HR = 0.45; 95%CI: 0.22–0.97; p = 0.027) years of follow-up. The benefit in OS remained significant in 101 patients with CVD treated with beta-blockers (HR = 0.65; 95%CI: 0.43–0.99; p = 0.045), and eventually statin, throughout the whole follow-up (log-rank p < 0.05). Further prospective studies are necessary to confirm the role of beta-blockers and statins in reduction of mortality in NSCLC patients undergoing radical CRT. Full article

The role of sequential chemoradiotherapy in non-small cell lung cancer (NSCLC) patients who are not eligible for concurrent therapy has not been clearly defined. The aim of this study was to determine the usefulness of Karnofsky performance status (KPS) monitoring and to define the factors determining clinical deterioration during sequential chemoradiotherapy in patients treated from July 2009 to October 2014. The study included 196 patients. The clinical stage was defined as III A in 94 patients (48%) and III B in 102 patients (52%). Reduced KPS was found in 129 patients (65.8%). Baseline KPS had no significant prognostic significance. Deterioration of KPS during chemoradiotherapy was observed in 53 patients (27%) and had a negative predictive value for both worse-progression free survival (HR = 1.44; 95% CI: 1.03–1.99; p = 0.03) and overall survival (HR = 1.42; 95% CI: 1.02–1, 99; p = 0.04). The deterioration of KPS correlated with the disease control rate 6 weeks after the end of chemoradiotherapy (p = 0.0085). The risk of KPS worsening increased with each subsequent day between the end of chemotherapy and the start of radiotherapy (OR = 1.03; 95%CI: 1.01–1.05; p = 0.001), but decreased with each year of older age of patients (OR = 0.94, 95% CI: 0.9–0.98, p = 0.009). The time between the end of chemotherapy and the start of radiotherapy determined the prognosis of NSCLC after chemoradiotherapy. It should be adjusted to the age of patients. Full article

Background: Social media are growing worldwide platforms for unlimited exchange of various content. Owing to their accessibility and short form, they can be utilized as usable, wide-range communication and information tools for companies, scientific communities, patient advocacy organizations, and special interest groups. This study aimed to investigate whether Instagram^® profiles can be reliable sources of information and knowledge about nutrition and dietetics. Materials and Methods: Random identification of nutrition-related posts was performed using a built-in website search engine. Posts were searched by five popular hashtags: #nutrition, #nutritionist, #instadiet, #diet, and #dietitian, 250 newest posts of each. Advertisement posts were discarded. Each eligible post was then categorized (dietetics, fitness, motivation, other) and assessed with regard to the quality of nutrition information provided (five levels from none to good quality), popularity (number of followers, likes, and comments), and engagement measures (like, comment, and engagement ratio). Results: A total of 1189 posts were reviewed. The overall quality of the content regarding nutritional knowledge was extremely low (93.9% of all posts), also when divided into categories. Among all posts, 63.8% were categorized as “nutrition and dietetics”, while “fitness”, “motivation”, and “other” categories comprised 8.2%, 4.8%, and 23.2% of the posts, respectively. Posts recognized as dietetics were the most liked (mean n = 116 likes per post) and of the highest quality. However, those motivational raised the greatest degree of engagement (32.7%). Posts with cooking recipes were the most commented. Conclusions: Random post search cannot provide viewers with valuable nutrition information. A dedicated search for high-quality professional profiles is preferred to obtain quality information. Full article

The aim of this study was to determine the influence of storage temperature and time on physicochemical parameters of starch syrups recommended for the winter feeding of bee colonies. The studies included commercially available three starch syrups and an inverted saccharose syrup that were stored at different temperatures: ca. 20 °C, 10–14 °C, and ca. 4 °C. Physicochemical parameters of fresh syrups (immediately after purchase) and syrups after 3, 6, 9, 12, 15, 18, 21, and 24 months of storage at the abovementioned temperatures were measured. It was observed that the rate of unfavorable changes in chemical composition of starch syrups and the inverted saccharose syrup, mainly the changes in the 5-hydroxymethylfurfural (HMF) content, depended on the type of a syrup and storage conditions (temperature, time). Properties of tested starch syrups intended for winter feeding of bees stored at ca. 20 °C maintained unchanged for up to 6 months, whereas the same syrups stored at lower temperatures (10–14 °C) maintained unchanged physicochemical parameters for about 12 months. In higher temperatures, the HMF content increased. To date, the influence of this compound on bees has not been thoroughly investigated. Full article

In recent time, it has become a common practice to use different kinds of starch syrups available on the market as a winter food for bees. However, the physicochemical composition of these syrups and their suitability for winter feeding of honeybee colonies are still insufficiently investigated. Therefore, our study analyzed the composition of three commercially available starch syrups, inverted saccharose syrup and homemade saccharose syrups, and tested winter stores processed by bees from these syrups. The following physicochemical parameters were investigated: water, sugars composition, maltodextrins (DP4–DP7) and 5-hydroxymethylfurfural (HMF) content, pH and free acidity, as well as electrical conductivity. We found that the sugar composition of starch syrups ensures the suitable sugar composition of winter stores processed by the bees from these syrups. Winter stores compared to fresh syrups had a high content of total fructose and glucose (50 g/100 g), and some amounts of maltose (15 g/100 g), maltotriose (4 g/100 g), and maltodextrins (4 g/100 g). The small percentage of maltodextrins is responsible for maintaining the liquid consistency of the winter stores in honeybee combs during storage. Water content not exceeding 17.2% and adequate pH value (around 4.00) guarantee the stability of winter stores during storage in honeybee combs. A HMF content of up to 50 mg/kg was safe for bee colonies during wintering. Full article

Wstęp: Niedoszacowanie liczby chorych na przewlekłą obturacyjną chorobę płuc (POChP) jest istotnym problemem klinicznym i społecznym. Wydaje się, że pomocna w identyfikacji osób z podejrzeniem POChP mogłaby być akcja spirometryczna przeprowadzana w przestrzeni publicznej. Celem badania było (1) oszacowanie wśród palących odsetka osób, które zgodzą się na wykonanie spirometrii, (2) ocena możliwości wykonania poprawnie technicznie spirometrii w czasie kampanii w przestrzeniu publicznej, oraz (3) ocena zależności między nasileniem objawów ze strony układu oddechowego a gotowością do wykonania spirometrii. Materiał i metody: Studenci medycyny rekrutowali do badania przechodniów w wieku > 40 lat, z wywiadem > 10 paczkolat palenia tytoniu. Po podpisaniu zgody ochotnicy wypełniali kwestionariusz z podstawowymi danymi osobowymi oraz klinicznymi, a następnie wykonywano badanie spirometryczne. Osoby z obturacją lub granicznymi wartościami parametrów spirometrycznych zapraszano do wykonania badań czynnościowych w warunkach poradni pulmonologicznej. Wyniki: Dziewięćset pięć osób spełniło kryteria włączenia do badania, spośród nich tylko 178 osób zgodziło się wypełnić kwestionariusz oraz wykonać spirometrię. U 22 osób stwierdzono obturację, u kolejnych 37 wysunięto podejrzenie obturacji dróg oddechowych. Z łącznie 59-osobowej grupy, tylko 15 pacjentów zgłosiło się na badanie kontrolne na oddziale szpitalnym w celu potwierdzenia wyników spirometrii wykonanej w przestrzeni publicznej. Na podstawie potwierdzonych wyników spirometrii szacuje się występowanie chorych ze świeżo rozpoznaną obturacją na 10.7%. Wnioski: Kampania spirometryczna w przestrzeni publicznej nie wydaje się skutecznym sposobem badań przesiewowych w kierunku POChP. Pomimo obecności objawów ze strony układu oddechowego osoby palące niechętnie poddają się spirometrii. Niniejsze obserwacje mogą w przyszłości być pomocne w opracowaniu programów badań przesiewowych w poszukiwaniu chorych na POChP.

Introduction: Underdiagnosis of COPD seems to be a relevant clinical and social problem. We hypothesized that active public spirometry campaign may help identify subjects with airflow limitation consistent with COPD. The aim of the study was (1) to evaluate the willingness of random smokers to undergo public spirometry, (2) to assess the ability to obtain an acceptable quality spirometry during a public campaign, and (3) to assess the relationships between the presence and severity of respiratory symptoms and readiness to undergo spirometry. Material and methods: Pedestrians aged > 40 years and a smoking history > 10 pack-years were recruited by medical students to fill a questionnaire and perform spirometry. Those with obstructive or borderline ventilatory insuffciency were invited and encouraged to undergo stationary spirometry in a pulmonary outpatient department. Results: Nine hundred and five subjects meeting the inclusion criteria were invited to the study. Only 178 subjects agreed to complete the questionnaire and undergo spirometry. Airway obstruction and borderline spirometry result (classified as possible airway obstruction) were found in 22 and 37 subjects, respectively. Of these, only 15 patients attended follow-up visit to verify public spirometry results. Extrapolation of the limited data showed the incidence of newly diagnosed airway obstruction as 10.7%. Conclusions: Public spirometry campaign does not seem to be an effective way of COPD screening. Smokers are reluctant to undergo complimentary spirometry even in the presence of pronounced respiratory symptoms. Our observations may be helpful in elaborating future screening programs for COPD.

Introduction: Primary germ cell tumours with mediastinal location comprise 1–6% of mediastinal tumours and 2–5% of all germ cell tumours occurring in adults. They are identified mostly in the 3^rd decade of life, in 90% of cases in men. The most common symptoms are dyspnea, chest pain, cough, fever and weight loss. The aim of the present study was the analysis of our own results of treatment of primary germ cell tumours with mediastinal location, and a review of the literature concerning this subject. Material and Methods: Five patients (4 males, 1 female) median age 27.8 years (range 23–30 years) treated in the period from 1999 to 2009 in Maria Sklodowska-Curie Memorial Cancer Centre and Institute of Oncology, Department of Lung Cancer and Chest Tumours in Warsaw, due to germinal tumours with primary mediastinal location, entered the study. Results: All patients received chemotherapy according to the BEP regimen. All patients achieved an objective response to treatment. Two patients died due to disease progression in spite of II- and III-line treatment. Three patients are still in follow-up. The median survival time was 55.8 months (range 8.0–120.0 months). Conclusions: Primary mediastinal germ cell tumours have worse prognosis than do those with gonadal location. Based on our observations and review of the literature, it can be concluded that the results of treatment of non-seminoma type germ cell tumours with primary mediastinal location remain poor. Patients who develop early recurrence or progression during first-line chemotherapy are particularly at risk of unfavourable outcome. Identification of new standards of treatment in tumours resistant to cisplatin require further studies evaluating the effectiveness of new generation cytostatic drugs. Full article

Introduction: Patients with advanced non-small cell lung cancer (NSCLC) have a very poor prognosis. Individualization of treatment and identification of therapeutic molecular targets may improve outcomes. Gefitinib was introduced recently among several other molecular-targeted drugs of activity in NSCLC. Gefitinib is indicated for patients diagnosed with advanced or disseminated NSCLC with an activating mutation in the EGFR (epidermal growth factor receptor) gene. The paper summarize experience with gefitinib in the Department of Lung and Thoracic Tumors of Maria Sklodowska-Curie Memorial Cancer Centre and Institute in Warsaw. Materials and methods: The group of 11 patients diagnosed with advanced NSCLC and activating mutations in the EGFR gene was analyzed. Patients were treated from April 2010 to April 2011. Tolerability, objective response rate (ORR) and progression free survival (PFS), which was calculated by the Kaplan-Meier method, were assessed. Results: Median observation time from the start of gefitinib treatment was 14 months (range 4,8–19 months). The rate of one-year survival in this group of patients was 91% (10 patients) with 54% of patients (6 patients) surviving one year without progression of disease. The ORR rate of 82% and median PFS 11.4 months were reached. No treatment-related deaths were reported. Among the complications skin toxicity (82%) and diarrhea (45%) were most frequently observed, in most cases the Common Toxicity Criteria for Adverse Events (CTCAE) first grade. Conclusions: The results confirm the literature data on the efficacy and safety profile of gefitinib in the treatment of patients with the diagnosis of advanced NSCLC and activating mutation in the EGFR gene.
