Efficacy of Original Paste in Treating Skin Ulcers Associated with Breast Cancer

Abstract

Locally advanced breast cancer often leads to ulcers that deteriorate the quality of life due to bleeding, exudate, malodor, and pain. Notably, there are no existing topical agents that can treat these symptoms and can be safely self-administered by patients. Therefore, we have developed and tested a original paste (Kishimoto paste ; K paste) that can be used safely and can simultaneously treat these symptoms.

We retrospectively examined the efficacy of K paste in 10 patients who used it between January, 2010 and January, 2020. At the initial visit, all the patients presented with ulcer exudate, nine had minor bleeding from the ulcer, eight had malodor associated with the ulcer, and seven had ulcer pain. The ulcer area was fully coated with K paste and subsequently covered with gauze.

There was an improvement or disappearance of symptoms and no side effects other than mild redness of the paste contact area were observed.

K paste was effective in treating various symptoms arising from skin ulcers associated with breast cancer. It is inexpensive and relatively safe to use without serious side effects. Hence, K paste has promising potential to treat patients with extensive breast cancer ulcers and associated symptoms that are difficult to control.
