If you have recently been diagnosed with melanoma, you may be wondering is interferon for treating melanoma is right for you.

What is Melanoma?

Melanoma, the most serious type of skin cancer, develops in the cells (melanocytes) that produce melanin — the pigment that gives your skin its color. Melanoma can also form in your eyes and, rarely, in internal organs, such as your intestines.

The Pros and Cons of Interferon for Melanoma Treatment

The value of a year of high-dose interferon-alfa2b (IFN) for the treatment of stage III melanoma after surgery remains a source of controversy among doctors and patients.

Some doctors recommend it to all stage III melanoma patients after surgery in order to prevent recurrence. But a substantial proportion say  that the limited benefit of IFN treatment does not justify its significant side effects.

Is IFN right for you?

Here are some of the pros and cons of interferon treatment to discuss with your doctor:

  1. IFN is the only medicine that has been approved for use in melanoma patients after surgery. Outside of clinical trials, it's all we've got.
  2. Some people tolerate interferon well and do receive a significant benefit from it in terms of preventing a relapse for a longer period of time. Also, many people feel that they need to do everything possible to fight their disease and that they would regret not taking IFN if the cancer returned.
  3. Unfortunately, IFN is not very effective in the majority of patients. A year’s worth of IFN treatment can delay the time to recurrence although half the time this delay will be less than one year. However, it is now known that the overall chance of recurrence and the overall survival time is not improved (contrary to some early studies that showed an increased survival time of about one year).
  1. IFN is associated with significant side effects in virtually all patients. The most frequently reported are flu-like symptoms, fatigue, muscle pain, depression and liver problems, some of which may worsen over the year of treatment.
  2. The schedule for taking interferon is challenging. Injections are usually done three times per week, at your home by yourself or a loved one. You'll also need to come into the doctor's office frequently for blood tests. This represents both a financial cost to you and the healthcare system.
  1. While you are taking IFN, it is impossible to know if it's working, since after surgery there are no tumors to measure. So during the year of IFN treatment, all you are aware of are the side effects -- and that can be psychologically difficult.

Ultimately, you need to ask yourself this question: How much is living without melanoma for less than a year more worth, knowing that there will be little or no effect on your overall long-term survival? Your doctor can give you advice, but only you know your need for physical and mental well-being, your desire to do everything possible, and thus what risk–benefit ratio is acceptable.
