Fluorouracil has been given systemically for anal, breast, colorectal, oesophageal, stomach, pancreatic and skin cancers (especially head and neck cancers). [12] It has also been given topically (on the skin) for actinic keratoses, skin cancers and Bowen's disease [12] (a type of cutaneous squamous-cell carcinoma), and as eye drops for treatment of ocular surface squamous neoplasia.

Topical 5-fluorouracil (5-FU, Efudex, Carac) has been shown to be an effective therapy for diffuse, but minor actinic cheilitis. 5-fluorouracil works by blocking DNA synthesis. Cells that are rapidly growing need more DNA, so they accumulate more 5-fluorouracil, resulting in their death. Normal skin is much less affected.
FOLFIRINOX is a chemotherapy regimen for treatment of advanced pancreatic cancer. It is made up of the following four drugs: It is made up of the following four drugs: FOL – folinic acid (leucovorin), a vitamin B derivative that enhances the effects of 5-fluorouracil (5-FU); [ 1 ] [ 2 ]
Adjuvant treatment in patients with stage III colon cancer is recommended [2] for 12 cycles, every two weeks. The recommended dose schedule is as follows: Day 1: Oxaliplatin 85 mg/m 2 intravenous (IV) infusion in 250-500 mL D5W and leucovorin 200 mg/m 2 IV infusion in D5W administered concurrently over 120 minutes in separate bags using a Y-line, followed by fluorouracil (5-FU) 400 mg/m 2 IV ...
The treatment is administered over a four-week cycle. On days 1 and 8 methotrexate and 5-FU are given as injections. Cyclophosphamide may be also administered intravenously in conjunction with these drugs, or may be taken as an oral tablet, taken once each day for the first 14 days of each cycle. [3]

The use of TS inhibitors has become a main focus of using TS as a drug target. The most widely used inhibitor is 5-fluorouracil (5-FU) and its metabolized form 5-fluorodeoxyuridine monophosphate (5-FdUMP), which acts as an antimetabolite that irreversibly inhibits TS by competitive binding. [13]
