Study of the Combination Carboplatin Plus Celecoxib in Heavily Pre-treated Recurrent Ovarian Cancer Patients

The aim of this study is to evaluate the antitumor activity and potential adverse effects of the combination celecoxib plus carboplatin in patients with recurrent, heavily pre-treated Ovarian Cancer (OC). The potential changes induced by the experimental combination on angiogenesis-related serum markers and quality of life measures will be also evaluated.The main objective is to evaluate the response rate. Secondary objectives are the following:toxicity;progression free survival;overall survival;duration of response;quality of life;modulation of angiogenesis-related molecules.
