I Chair and Department of Gynecological Oncology and Gynecology is a specialist research center providing help in diagnostics and treatment of gynecological malignancies. The research work is focused on the processes of angiogenesis and lymphangiogenesis. Development of blood and lymphatic vessels is subject to research in a wide range of malignancies, including ovarian cancer, endometrial cancer and uterine sarcomas. Angiogenesis in malignancies of the female genital tract is investigated by using some modern 3D sonography that uses high-definition blood flow imaging. Ovarian Tumors and Early Ovarian Cancer Detection unit was established in 2002 and since that time more than 3500 patients with difficult to diagnose tumors have been consulted and treated in the Department. Ovarian cancer immunology studies are the second leading research fiekld in the 1st Chair Department of Gynecological Oncology and Gynecology. The Department is well equipped with diagnostic devices as well as a scientific laboratory. This allows for studies in the fields of imaging of masses, their immunology, biochemistry and molecular biology. Understanding immunological response in patients with ovarian cancer is the key to develop new, effective therapies, including immunological vaccines. In this area we are cooperating with prominent international research centers: Department of Surgery, University of Michigan and Department of Microbiology and Immunology, University of Arkansas. Results of our research are published in both Polish and international journals specializing in fields of gynecology, oncology, immunology and basic science.

Introduction. Blood biomarkers may support early diagnosis of lung cancer by enabling pre-selection of candidates for computed tomography screening or discrimination between benign and malignant screening-detected nodules. We aimed to identify features of serum metabolome distinguishing individuals with early-detected lung cancer from healthy participants of the lung cancer screening program. Methods. Blood samples were collected in the course of a low-dose computed tomography screening program performed in the Gdansk district (Northern Poland). The analysis included 31 patients with screening-detected lung cancer and the pair-matched group of 92 healthy controls. The gas chromatography coupled to mass spectrometry (GC/MS) approach was used to identify and quantify small metabolites present in serum. Results. There were several metabolites detected in the sera whose abundances discriminated patients with lung cancer from controls. Majority of the differentiating components were downregulated in cancer samples, including amino acids, carboxylic acids and tocopherols, whereas benzaldehyde was the only compound significantly upregulated. A classifier including nine serum metabolites allowed separation of cancer and control samples with 100% sensitivity and 95% specificity. Conclusions. Signature of serum metabolites discriminating between cancer patients and healthy participants of the early lung cancer screening program was identified using a GC/MS metabolomics approach. This signature, though not validated in an independent dataset, deserves further investigation in a larger cohort study.

The aim of the present study was to perform comparative analysis of serum from patients with different stages of non-small cell lung cancer (NSCLC) using the three complementary proteomic approaches to identify proteome components associated with the progression of cancer. Serum samples were collected before any treatment from 200 patients with NSCLC, including 103 early stage, 64 locally advanced and 33 metastatic cancer samples, and from 200 donors without malignancy. The low-molecular-weight fraction of serum proteome was MALDI-profiled in all samples. Serum proteins were characterized using 2D-PAGE and LC-MS/MS approaches in a representative group of 30 donors. Several significant differences were detected between serum samples collected from patients with early stage cancer and patients with locally advanced cancer, as well as between patients with metastatic cancer and patients with local disease. Of note, serum components discriminating samples from early stage cancer and healthy persons were also detected. In general, about 70 differentiating serum proteins were identified, including inflammatory and acute phase proteins already reported to be associated with the progression of lung cancer (serum amyloid A or haptoglobin). Several differentiating proteins, including apolipoprotein H or apolipoprotein A1, were not previously associated with NSCLC. No significant differences in patterns of serum proteome components were detected between patients with adenocarcinoma and squamous cell carcinoma. In conclusion, we identified the biomarker candidates with potential importance for molecular proteomic staging of NSCLC. Additionally, several serum proteome components revealed their potential applicability in early detection of the lung cancer.

Autosomal dominant polycystic kidney disease produces symptoms mainly in adulthood. Renal cysts and/or elevated blood pressure can be the first signs of the disease in children. Because of the lack of a targeted therapy, early diagnosis and implementation of actions to slow its progression are the essence of treatment. Aim: The aim of the study was to assess the clinical course of autosomal dominant polycystic kidney disease in children. Material and methods: The study involved the assessment of 28 patients with autosomal dominant polycystic kidney disease diagnosed before the age of 18. The disease was diagnosed during a routine abdominal ultrasound scan in 24 patients and during a scan conducted due to abdominal pain reported by patients in 4 cases. Two patients had the disease diagnosed based on the Ravine criteria, whereas an ultrasound image and family history helped establish the diagnosis in 26 cases. The children enrolled had blood pressure measured, serum creatinine concentration determined and general urinalysis performed. Results: The median age at the diagnosis was 5 years. The family history was positive in 89.3% (25) of patients. Siblings had the disease in 46.43% (13) of cases. None of the children presented with abnormalities in urinalysis or creatinine levels. Two patients were diagnosed with arterial hypertension and in 1 child blood pressure was elevated above the 97th percentile. Urine albumin-to-creatinine ratio exceeding 30 mg/g was observed in 20.8% of children. Conclusions: Autosomal dominant polycystic kidney disease in children is asymptomatic. There are no irregularities either in urinalysis or renal function parameters. An abdominal ultrasound examination, which is inexpensive and non-invasive, is worth considering in all children of parents with autosomal dominant polycystic kidney disease in order to implement early nephroprotection.

Wielotorbielowatość nerek dziedziczona autosomalnie dominująco daje objawy kliniczne głównie w wieku dorosłym. U dzieci pierwszymi oznakami choroby mogą być obecność torbieli w nerkach i/lub podwyższone ciśnienie tętnicze krwi. Istotą leczenia, ze względu na brak terapii celowanej, jest wczesne wykrycie choroby i wdrożenie działań, które ją spowolnią. Cel pracy: Celem pracy była ocena przebiegu klinicznego autosomalnie dominującej wielotorbielowatości nerek u dzieci. Materiał i metody: Badaniem objęto 28 osób, u których wielotorbielowatość nerek dziedziczoną autosomalnie dominująco rozpoznano poniżej 18. roku życia. U 24 chorobę zdiagnozowano w trakcie rutynowego badania ultrasonograficznego jamy brzusznej, natomiast u 4 na podstawie badania wykonanego z powodu zgłaszanych dolegliwości bólowych brzucha. U 2 osób wielotorbielowatość nerek dziedziczoną autosomalnie dominująco rozpoznano na podstawie kryteriów Ravine’a, a u 26 na podstawie obrazu ultrasonograficznego i wywiadu rodzinnego. U badanych dzieci zmierzono ciśnienie tętnicze, oznaczono stężenie kreatyniny w surowicy oraz wykonano ogólną analizę moczu. Wyniki: Mediana wieku, w którym rozpoznano chorobę, wyniosła 5 lat, wywiad rodzinny był dodatni u 89,3% (25) osób, rodzeństwo chorowało w przypadku 46,43% (13) pacjentów. U żadnego dziecka nie stwierdzono odchyleń w badaniu ogólnym moczu ani w stężeniu kreatyniny. U 2 osób zdiagnozowano nadciśnienie tętnicze, a 1 miała podwyższone wartości ciśnienia tętniczego powyżej 97. centyla. U 20,8% dzieci stwierdzono stosunek stężenia albumin do stężenia kreatyniny w moczu powyżej 30 mg/g. Wnioski: Wielotorbielowatość nerek dziedziczona autosomalnie dominująco w dzieciństwie przebiega bezobjawowo, nie stwierdza się również odchyleń w badaniu ogólnym moczu ani w funkcji nerek. Badanie ultrasonograficzne jamy brzusznej, które jest tanie i nieinwazyjne, warto wykonywać u wszystkich dzieci rodziców z wielotorbielowatością nerek dziedziczoną autosomalnie dominująco w celu wczesnego wdrożenia nefroprotekcji.
