Question:
First Course Treatment/Immunotherapy--Colon: Is infliximab cancer directed treatment? See Discussion.
Discussion:
While SEER*Rx does indicate infliximab should be coded as biological response modifier (BRM)/Immunotherapy, the manufacturer website for this medication indicates it is given for: Crohn’s disease, ulcerative colitis, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis. In addition, SEER*Rx does not indicate which primary sites this treatment may be given for. If it is indeed cancer directed treatment, can the typical primary sites be added for clarity?
Case example: Patient is diagnosed with colorectal cancer and also has an existing diagnosis of Crohn’s disease; received surgery and FOLFOX6, as well as infliximab. There was no statement of what disease the infliximab was given to treat.
Answer:
infliximab is not cancer-directed treatment. This drug was last updated by the FDA 2/22/2023 with additional information on its approval to treat non-malignant neoplasms. To date, the FDA has not approved it for use in colon cancer. This drug was intially developed to treat colon cancer; however, found to be ineffective treating cancer.
