Ovarian 3c possible peritoneal reccurance

I'm 2 months into remission of Stage III C papillary serous mixed low high grade ovarian cancer. Just had a CT that showed:

 Several new areas of wispy and poorly defined soft tissue thickening in the mesentery, along the serosal surface of the proximal ascending colon and in the pelvic fat as well as new trace pelvic free fluid, strongly concerning for recurrent peritoneal disease. 

I have a PET scan scheduled next week. Just hoping anyone with experience in peritoneal  reccurance can share. Thanks.
