Final answer:
Risk factors that predict an allergic reaction to cetuximab include contact dermatitis, delayed-type hypersensitivity, weakened immune system, precancerous skin lesions, and exposure to radiation or toxic substances.
Step-by-step explanation:
To predict an allergic reaction to cetuximab, risk factors such as a history of atopy, personal or family history of skin cancer, and weakened immune system are indicators. Additionally, pre-existing conditions like chronic asthma or allergic rhinitis can increase the risk due to IgE-mediated mast cell activation.
Risk factors that can predict an allergic reaction to cetuximab include the following:
- Contact dermatitis, which involves exposure to latex.
- Delayed-type hypersensitivity, which manifests as a tuberculin reaction.
- Having a weakened immune system.
- Being diagnosed with precancerous skin lesions or having a personal or family history of skin cancer.
- Being exposed to other forms of radiation or certain toxic substances such as arsenic.
