Study Overview
Brief Summary
This phase II trial studies how well computed tomography perfusion imaging works in predicting outcomes in patients with ovarian, fallopian tube, or primary peritoneal cancer who are receiving bevacizumab. Computed tomography perfusion imaging monitors the effects of the drug treatment on the blood flow to the tumor, and may help to predict whether a certain drug therapy is likely be successful in a patient with ovarian, fallopian tube, or primary peritoneal cancer.
Detailed Description
PRIMARY OBJECTIVES:
I. To evaluate whether those patients with an increase in perfusion computed tomography (CT) tumor blood flow (BF) from T0 to T1 demonstrate poorer progression-free survival (PFS) compared to those patients with a decrease in BF from T0 to T1, among platinum-resistant, recurrent ovarian cancer patients treated with bevacizumab.
SECONDARY OBJECTIVES:
I. To evaluate whether change in perfusion CT tumor BF from T0 to T1, as a continuous variable, is associated with PFS.
II. To evaluate whether changes in perfusion CT tumor blood volume (BV) or permeability surface product area (PS) from T0 to T1 are associated with PFS.

Outcomes
Primary Outcomes
Progression Free Survival (PFS)
Time Frame: Time to progression or death from the T1 scan, assessed up to 18 months
The PFS of patients with increased tumor blood flow (BF) from T0 to T1 will be compared with that of patients with decreased tumor BF from T0 to T1. Kaplan-Meier survival curves will be generated, and a two-sided log-rank test will be used to compare PFS between the two groups.
Secondary Outcomes
- Objective Response Rate(Up to 18 months)
