Hello. We should proceed with a biopsy from the sigmoid mass/ omental deposit.
After confirming the malignancy- an MSI testing should be done on the biopsy & KRAS and BRAF genetic testing.
Now for the treatment part- he needs to be assessed if he's in obstruction or not.
If in obstruction- we might need a diversion colostomy followed by chemotherapy/ immunotherapy depending on his MSI status.
If not in obstruction- proceed with chemo/ immunotherapy depending on the MSi status
