Example orders for FLOX in colon cancer
Remember that example order sets that may contain additional information about supportive medications, suggestions for monitoring, hydration, and pre-treatment screening information for chemotherapy regimens are purely anecdotal, provided only as examples of what some other providers may be using, and are typically not based on references in the primary literature.
