SWOG S2015: Comparing Resection Options in Melanoma Removal

What is the Purpose of this Study?

We are doing this study to find out how much skin should be removed from around a melanoma to lower the chances of the melanoma coming back. We don't have enough evidence to know exactly how much skin to remove around the melanoma to give people the best chance at a good outcome.

What is the Condition Being Studied?


Who Can Participate in the Study?

Adults ages 18+ who:

  • Are diagnosed with stage II primary invasive cutaneous melanoma
  • Are planning to have surgery to remove the melanoma
  • Have enough skin around the melanoma to leave at least a 2 cm margin when it is resected (cut out)

Age Group

What is Involved?

If you choose to join this study, you will be randomly assigned (like a coin flip) to 1 of 2 groups:

  • One group will have surgery that removes a 1-cm margin of health skin from around the melanoma
  • The other group will have surgery that removes a 2-cm margin of health skin from around the melanoma

After surgery, your doctor will continue to follow your condition for 5 years. During the first 2 years after surgery, you will visit the study doctor 3, 6, 12, 18, and 24 months after surgery. After that, you will visit the study doctor once a year.
