What is 5-FU used for?
5-Fluorouracil (5-FU) is a common chemotherapeutic for the treatment of different malignancies, including carcinomas of the gastrointestinal tract, breast, and skin [1]. The rate-limiting enzyme in the catabolic pathway is dihydropyrimidine dehydrogenase (DPD), and studies have shown that decreased DPD activity leads to less drug clearance and increased toxicity [1]. Toxicities from systemic exposure include diarrhea, stomatitis, mucositis, pancytopenia, sepsis, cardiotoxicity, and—in some cases—death [2, 3]. The treatment for actinic keratosis includes cryotherapy, topical 5-FU, topical imiquimod, topical diclofenac, photodynamic therapy, and surgical excision. Topical 5-FU has been a gold standard treatment for years, especially with multiple lesions [4]. The most common side effects from topical 5-FU include skin irritation with associated erythema, dryness, and burning [4]. Very few reports of severe adverse reactions from topical 5-FU exist, but reactions include allergic contact dermatitis and inflammatory colitis [4]. Only one known life-threatening case of toxicity has been reported from topical 5-FU [1], but this case was reported after 5% 5-FU. To our knowledge, no similar adverse event has been reported with the lower-strength 0.5% 5-FU in the literature.
Can 5-FU be used to detect DPD?
Because 5-FU is commonly used, and severe toxicity effects are associated with DPD deficiency, several methods have been developed to detect DPD deficiency. These include genotyping, radio-immunoassays, and measuring serum uracil concentrations, but these tests are expensive and time-consuming [9]. Given the rarity of life-threatening adverse events caused by topical 5-FU, developing a test to detect DPD deficiency would be more suitable for systemic therapy.
Is 5 fluorouracil cream life threatening?
We report a life-threatening reaction, possibly from topical 0.5% 5-fluorouracil cream, which is a lower strength dose than the only reported case of a life-threatening adverse event with 5.0% 5-fluorouracil cream.
Is 5 FU a life threatening drug?
Johnson and Diasio [5] reported the first patient with cancer known to develop life-threatening reactions after treatment with topical 5% 5-FU. This patient was found to be deficient in DPD, which contributed to the life-threatening toxicity. Review of the literature suggests approximately 3–5% of the general population have partial DPD deficiency [3]. In addition, DPD deficiency has been reported to be responsible for at least 50% of severe 5-FU treatment toxicity [3]. Further, 5-FU has been shown to have a narrow therapeutic index, and the literature also demonstrates it has a marked individual pharmacokinetic variability [6]. Therefore, a certain dose may produce a therapeutic response in one individual but a possible life-threatening toxicity in another [7, 8].

How to treat invasive basal cell carcinoma?
When treating invasive basal cell carcinoma (BCC) with Mohs micrographic surgery (MMS), including infiltrative and nodular subtypes, the goal is complete surgical removal of the tumor. In some cases, after several stages of MMS, residual foci of superficial BCC are noted with no dermal invasive components apparent. Some patients and surgeons have opted for halting surgery and treating residual superficial BCC with adjuvant topical fluorouracil. In this retrospective study, this treatment method is shown to be effective with a recurrence rate of BCC of 3.7% over a mean follow-up of 28 months. This treatment method reduces the number of stages of MMS as the surgery is stopped was invasive BCC is removed. This can be beneficial when considering the morbidity of prolonged surgical procedures in frail, elderly patients experiencing surgical fatigue, the cost of additional stages, and the cost of advanced repairs due to enlarging defect size.
