Im having my port-a-cath implanted on Jan 2 and will start a bi-monthly Flofox or Flofiri infusion treatments soon after. Also, I'll be part of a clinical trial on a new drug (onvansertib). My latest CT scan report includes:

1. Peritoneal carcinomatosis with small volume ascites. Tumor implants on the gastric serosa and undersurface of the right hemidiaphragm.
2. Hypodense liver lesions could be parenchymal metastatic disease versus post-resection changes versus residual tumor in the background of post-resection changes. Comparison to prior imaging would be helpful.
3. Indeterminate splenic lesion.
4. Subcutaneous nodules of the anterior abdominal wall could represent port sites versus metastatic implants in the port sites. Again, comparison to prior would be helpful.

I've had three resection surgeries: 1 colon and 2 liver to remove polyps and lesions. I understand my stage IV colorectal cancer is not curable but would like to know how chemotherapy works. What can I expect?
Any help would be appreciated.
