A Multicenter Trial On The Utility and Impact Of Computed Tomography and Serum CA-125 In the Management of Newly Diagnosed Ovarian Cancer

Study Overview
=================
Brief Summary
-----------------
The purpose of the research is to determine if blood tests and a CT scan done before surgery can predict how successful the surgery will be. In patients who have cancer of the ovary that has spread, it is hoped that the CT scan will be able to identify the various places where the cancer has spread so that additional surgeons can be available to help with the surgical procedure. If you have confirmed stage 3 or 4 ovarian, fallopian tube, or primary peritoneal cancer, you may undergo a CT scan of the abdomen and pelvis after the surgery to compare how much cancer the surgeon thought was left after surgery to what is seen on CT scan. A CT scan of the chest will be done if your physician thinks it is necessary.

Detailed Description
-----------------
This study is designed to assess the utility and impact of computed tomography (CT)scanning of the abdomen and pelvis and preoperative serum CA-125 levels in the management of patients undergoing surgery for presumed ovarian cancer.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To assess the efficacy of preoperative CT scan of the abdomen and pelvis in predicting optimal primary cytoreduction in advanced ovarian cancer. |  | 7 - 35 days postop stage 3 or 4 disease CTscan have | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To evaluate the ability of preoperative serum CA-125 to predict optimal primary cytoreduction of advanced ovarian cancer. |  | Within 14 days prior to surgery | 
| To develop preoperative CT scan of the abdomen and pelvis and/or tumor marker criteria for ovarian cancer non-resectability (sub-optimal tumor cytoreduction). |  | 3 years | 
| To determine the ability of preoperative CT scan of the abdomen and pelvis to provide useful information that will impact on surgical planning. |  | 3 years | 
| To compare the intraoperative assessment of residual disease to that found on postoperative CT scan of the abdomen and pelvis, if scans are available for review. |  | 3 years |
