  16. Treatmetn options for localized (stage I-II) colon cancer
    • Surgical resection of primary tumor + regional mesenteric LN
    • Selected patients with Stage II disease may benefit from adjuvant systemic therapy
  17. tx for stage I rectal cancer
    surgical resection
  18. tx for stage II and III rectal cancer
    • surgery followed by radiation therapy with 5FU
    • regimins may include oxaliplatin, LV, or capecitabine

    • cetuximab + irinotecan
    • panitumumab
  21. what do you do if you get a clot from bevacizumab
    • venous = keep on treating
    • arterial = d/c drug
