Quantification of biomarkers will be performed on 100 patients treated with bevacizumab through the collection of the following samples at different timepoints: 1 serum sample; 2 CTAD plasma samples; 2 K2EDTA plasma samples. The samples will be collected as follows: before the start of chemotherapy; 3 weeks after start of chemotherapy, before start of treatment with bevacizumab; 9 weeks after start of chemotherapy; 15 weeks after start of chemotherapy; 52 weeks after start of chemotherapy; at progression of disease.

Quantification of biomarkers will be performed on 50 patients treated with chemotherapy through the collection of the following samples at different timepoints: 1 serum sample; 2 CTAD plasma samples; 2 K2EDTA plasma samples. The samples will be collected as follows: before the start of chemotherapy; 3 weeks after start of chemotherapy, before start of treatment with bevacizumab; 9 weeks after start of chemotherapy; 15 weeks after start of chemotherapy; 52 weeks after start of chemotherapy; at progression of disease.

Collection of blood samples during blood draws performed before each cycle of chemotherapy as per clinical practice.

Observational study. Blood samples will be collected at scheduled blood draws performed as per clinical practice before each cycle of chemotherapy.

This is a monocentric prospective observational pilot study of translational research in women with advanced ovarian epithelial cancer. The main purpose of this study is to evaluate the predictive value of response to treatment with bevacizumab of the circulating levels of Ang1, Tie2 and VEGF before start of therapy. Secondary aims of the study are to explore the predictive value of response / resistance to bevacizumab of changes in circulating levels of Ang1 and Tie2 during treatment and at progression of disease, and to explore the possible role of circulating VEGF in the modulation of bioavailability of bevacizumab.

Evaluation of the Predictive Value of Blood Levels of Angiopoietin 1 and Endothelial Internal Tunica Cell Kinase 2 in Patients With Ovarian Cancer Treated With Chemotherapy Associated to Bevacizumab

Prospective Pilot Study for the Evaluation of the Predictive Value of Blood Levels of Angiopoietin 1 (ANG1) and Endothelial Internal Tunica Cell Kinase 2 (TiE2) in Patients With Ovarian Cancer Treated With Chemotherapy Associated to bevAcizumab

Relationship between baseline values of Ang1 and Tie2 (considered individually or combined with each other) and response to treatment with bevacizumab (according to RECIST 1.1 criteria).

Relationship between baseline values of endogenous VEGF (plasma CTAD levels) and released by platelets during the clot phase (serum levels) and response to treatment with bevacizumab.

relationship between Ang1 and Tie2 levels at baseline, during chemotherapy administration and at progression of disease.

possible anticipation of diagnosis of progression of disease through evaluation of Ang1 and Tie2

Evaluation of free VEGF, bevacizumab-bound VEGF and available bevacizumab in relation to clinical response
