Major Research Findings
Floxuridine is a fluoropyrimidine derivative used in the treatment of malignant tumors. This paper evaluated the efficacy and safety of floxuridine alone or in combination with radiation therapy in a multi-institutional trial. 10 . Floxuridine is also used in the treatment of colorectal cancer with liver metastasis, and it has been shown that the effect is more effective in combination with radiation therapy than single administration. 23 . In addition, floxuridine has been shown to be effective in the treatment of advanced breast cancer and ovarian cancer, and some studies have also investigated the effectiveness of combination therapy with floxuridine and other drugs. 21 25 8 6 5 . It has also been shown that adjusting the floxuridine administration schedule can increase the efficacy of the drug while reducing side effects. 19 26 .
Reasons for Side Effects
Side effects of floxuridine are caused by the drug's inhibition of cellular DNA synthesis. DNA synthesis is essential for cell proliferation, so floxuridine inhibits the growth of cancer cells, but it also inhibits the growth of normal cells, resulting in side effects.
Common Side Effects
Gastrointestinal
The most common side effects of floxuridine are gastrointestinal side effects. This is because the drug inhibits the proliferation of cells in the gastrointestinal tract. Specific side effects include diarrhea, nausea, vomiting, anorexia, and stomatitis. These side effects can worsen with increasing floxuridine doses. Diarrhea is one of the most common side effects of floxuridine administration and can be serious. 21 10 29 11 14 16 3 2 17 .
Hematologic
Floxuridine can also inhibit the proliferation of cells in the bone marrow, leading to a decrease in the number of white blood cells, red blood cells, and platelets. This can make the patient more susceptible to infections, anemia, or bleeding. 10 28 .
Neurological
Floxuridine can also affect the nervous system. Specific side effects include dizziness, headache, numbness, and sensory disturbances. 28 . In severe cases, the patient may experience altered consciousness or coma.
Skin
Floxuridine can also affect the skin. Specific side effects include rash, dry skin, and itching. 10 .
Liver
Floxuridine can also affect the liver. Specific side effects include liver function abnormalities and jaundice. Liver damage can worsen with increasing floxuridine doses. 22 . It has been reported that floxuridine administration may increase the fat content of the liver. 22 .
Countermeasures for Side Effects
Gastrointestinal
To reduce gastrointestinal side effects, dietary and drug therapy may be used. Dietary therapy involves eating easily digestible foods and avoiding irritants. Drug therapy includes the use of antiemetics, antidiarrheals, and prokinetics. Reducing the dose of floxuridine can also reduce side effects. 21 .
Hematologic
To reduce hematologic side effects, drugs called hematopoietic growth factors are used. Hematopoietic growth factors promote the proliferation of cells in the bone marrow, increasing the number of white blood cells, red blood cells, and platelets. 25 . Antibiotics may also be administered to prevent infection.
Neurological
Drug therapy is used to reduce neurological side effects. Specifically, antiemetics, analgesics, and anticonvulsants are used.
Skin
Moisturizers and steroid ointments are used to reduce skin side effects.
Liver
Drugs that aim to improve liver function are used to reduce liver side effects. Reducing the dose of floxuridine can also reduce side effects. If liver function deteriorates, floxuridine administration may need to be stopped. 22 .
Comparison of Studies
Commonalities of Studies
Multiple studies have shown that floxuridine is effective in the treatment of malignant tumors. In addition, it is common for side effects of floxuridine administration to be diverse, affecting the gastrointestinal tract, hematopoietic system, nervous system, skin, and liver.
Differences in Studies
There may be differences in efficacy and side effects between single administration and combination with other drugs. For example, when floxuridine is combined with radiation therapy, it has been shown to be more effective than single administration. 23 . In addition, combination therapy of floxuridine with other drugs may increase side effects. 21 25 8 6 5 .
Notes on Real-Life Application
Floxuridine is a drug used in the treatment of cancer. Therefore, it is very dangerous to take it or stop taking it without consulting a doctor. To prevent the occurrence and worsening of side effects, be sure to take it as directed by your doctor. In addition, floxuridine may interact with other drugs. If you are taking other medications, be sure to consult your doctor.
Limitations of Current Research
Research on floxuridine side effects is not yet sufficient. In particular, research on long-term side effects is lacking. In addition, although floxuridine is used for various types of cancer, side effects may vary depending on the type of cancer. Furthermore, individual constitution can also affect the incidence and severity of side effects.
Future Research Directions
To further elucidate the side effects of floxuridine, long-term safety research, comparative research on side effects in various types of cancer, and research on individual differences in side effects are needed in the future.
Conclusion
Floxuridine is an effective drug used in the treatment of malignant tumors, but it may cause a variety of side effects, affecting the gastrointestinal tract, hematopoietic system, nervous system, skin, and liver. To prevent the occurrence and worsening of side effects, it is important to take it as directed by your doctor. It is hoped that future research on the side effects of floxuridine will lead to the development of safer and more effective treatments.
