Abstract: The invention is directed to a method of diagnosing a malignant ovarian tumor disease in a subject, which comprises —providing a sample of peripheral blood cells (PBC) of the subject, —measuring the expression of a multimarker gene panel comprising at least NEAT1, BC037918, C1 orf63, PRIC285, OSM, and optionally further genes or protein markers, and —comparing to a reference value, the differential expression being indicative of a malignant ovarian tumor, and a set of reagents to determine the expression of such a multimarker panel, as well as the use of a PBC-expression based test to improve the diagnosis of ovarian cancer. The invention further relates to a method of determining the expression of at least one of the RPL21, RPL9 and/or SH3BGRL3 genes in a PBC sample of a subject as internal control.

Abstract: A method of determining gynaecologic tumor disease in a subject by providing a sample of peripheral blood of the subject, measuring the PPIC expression of cells in the sample, and comparing this to a reference value, the PPIC overexpression being indicative of a gynecologic tumor disease and/or disease progression, including metastatic potential in a gynecologic cancer patient.

Abstract: The invention relates to a method and a test kit for diagnosing ovarian cancer and/or making predictions in case of ovarian cancer as well as a method for estimating the effectiveness of therapeutic agents during the treatment of ovarian cancer, the promoter hypermethylation of the TUSC3 marker in a biological sample that is to be analyzed, preferably in a tissue sample or biological liquid that is to be analyzed, being measured. The result of said method can be used for planning an ovarian cancer treatment.
