Patient's question:
August 2012Doctor's answer:
1) Chemotherapy with Drugs① Topical Medications: Commonly used include 20% podophyllotoxin, 0.5% etoposide (), 1% podophyllin, 5% 5-fluorouracil ointment, 30%-50% trichloroacetic acid solution, and 0.5% acyclovir cream, among others. Among these, etoposide and 5-fluorouracil are cytotoxic agents, contraindicated in pregnant women due to their high local irritability, which can cause redness, swelling, erosion, and pain. The recurrence rate after treatment is also relatively high.
② Local Injections: Interferon preparations are commonly used in clinical practice, with adriamycin also being employed. The primary role of interferon is immune regulation against viruses.
③ Systemic Drug Application: Systemic medications are generally used in conjunction with local treatments. Commonly used drugs include interferon and other antiviral and immune-regulating agents, which have some efficacy in reducing recurrence. However, due to their high cost, numerous side effects, and uncertain efficacy, they are generally not recommended for clinical use.
