Testing for DPD/DPYD deficiency prior to the start of chemotherapy with 5-FU (Fluorouracil) or Capecitabine (Xeloda) can reduce suffering and save lives.

Testing for DPD/DPYD deficiency prior to the start of chemotherapy with 5-FU or Capecitabine (Xeloda) can reduce suffering and save lives.

Testing for DPD/DPYD deficiency is becoming the standard of care across Europe and in select institutions in the US: it is time for it to become THE standard of care across all of the US.

What you need to know:

  • Fluorouracil (5-FU) and Xeloda (Capecitabine) are used to treat tumors typically found in gastrointestinal, breast, and head/neck cancer patients.
  • The DPD enzyme plays an essential role in removing 5-FU from the body; when DPD enzyme activity is diminished, standard 5-FU results in 50-88% risk of severe toxicity (hospitalization/treatment delays) and 10% fatalities.
  • The death rate in the US is estimated at 700 to 1,400 annually.
  • Genetic variants of the DPYD gene have been shown to lead to compromised DPD enzyme activity as first reported in 1988 by Dr. Robert Diasio. These variants are present in 5-8% of European and 5% of African American descendants.
  • Tests are available to detect DPD deficiency and have been demonstrated to be life-saving and cost effective.
  • In most cases, patients with DPD deficiency are asymptomatic prior to receiving 5-FU or Xeloda which is why pre-screening is the best means to ensure safe treatment.
  • The European Medicines Agency has recommended pre-screening and therapeutic dose management since 2020.
  • US guidelines, however, published by the National Comprehensive Cancer Network (NCCN) and the US Food and Drug Administration’s (FDA) drug labels do not require pre-screening. In 2022, the FDA suggested physicians discuss the possibility of testing with patients but has not moved to require pre-screening.
  • Despite the absence of clear guidelines, a number of institutes in the US are now pre-screening patients to include the Dana Farber Cancer Institute, St Jude’s Hospital, Cleveland Clinic, and Johns Hopkins among others.

Why Test?

Approximately 5-7% of patients carry genetic DPYD variants that can lead to much greater risk of severe toxic reactions or death.

Treatment Warning Signs

If you think that you are having a moderate to severe reaction on your first or second round of chemotherapy, you should contact your healthcare provider immediately.

Working with Your Oncologist

You will need to initiate discussion of testing for DPD/DPYD deficiency with your oncologist because it is NOT the standard of care in the US.

EU: LEADERS IN THE STANDARD OF CARE

These countries/provinces are leading the way in patient care by either Recommending or Requiring DPD testing prior to the start of treatment.

USA: LATE TO IMPROVE STANDARD OF CARE

US authorities have not required or recommended DPD testing. There are, however, a few institutes in the US that have started testing patients.

Consult your oncologist to order tests to ensure your safety.
