Hypothesis The One-Step Nucleic Acid Amplification method could represent an effective intraoperative tool for detection of metastatic involvement of lymphatic nodes on the level of ultrastaging in endometrial cancer patients. Objective Utilization of the One-Step Nucleic Acid Amplification (OSNA) molecular biology method for the detection of the micrometastatic and macrometastatic involvement of sentinel lymph nodes in endometrial cancer patients. The objective is a comparison with the conclusion of the histopathological ultrastaging of sentinel lymph nodes and a description of the clinical consequences of this method. Methods Patients indicated for the surgical treatment of endometrial cancer underwent the detection of sentinel lymph nodes that was executed using the intracervical application of a tracer. Nodes larger than 5 mm were cut into sections 2 mm thick parallel to the short axis of the node. Odd sections were examined using the OSNA method, while even ones were examined by hematoxylin and eosin (H&E) and immunohistochemical examination to detect cytokeratin 19 antibody (IHC CK19) based on an ultrastaging-relevant protocol. Nodes of the size of 5 mm and smaller were divided into halves along the longitudinal axis with one half being examined using the OSNA method and the other half by...

Structured abstract Study objectives: Ovarian carcinoma 1/ comparison of sensitivities among monitored markers CA 125, HE4, CA 19-9, CEA, TK, TPS, MonoTotal 2/ comparison of false positivity of markers CA 125 and HE4 3/ use of CA 125, HE4 and ROMA index in the diagnostics of ovarian carcinoma 4/ use of CA 125 and HE4 in the follow-up of ovarian cancer Endometrial carcinoma 1/ feasibility of use of biomarkers CA125 and HE4 in patients with endometrial cancer in pre- operative management Study design: Retrospective data analysis Settings: Department of Obstetrics and Gynecology, Medical Faculty and Teaching Hospital in Pilsen Patients and Methods: Ovarian cancer 1/ Sensitivity of markers CA 125, HE4, CA 19-9, CEA, TK, TPS, and MonoTotal was assessed in 266 patients - 19 with ovarian cancer and 247 with benign disorders. 2/ False positivity of markers CA125 and HE4 was evaluated in a total of 390 patients with benign diagnoses - 60 women with endometriosis, 70 pregnant patients, 67 patients with ascites, 60 with pleural effusion, 25 with cardiac failure , 80 with renal insufficiency and 28 with hepatic failure. 3/ As a part of this objective we evaluated 552 patients with abnormal pelvic abnormality - 30 women had a histologically confirmed malignant ovarian tumor. Other 522 women had a benign condition. The...
