Neoplasms

Intervention(s):

Experimental group: Bioactive Formula (patent US 9089580 B1). Intra-cystic application of the solution called bioactive formula. Initially the fluid is drained from the cyst. The dose depends on the amount of fluid that was drained from the cyst. Liquid drainage less than 4mL: Apply half a milliliter of bioactive formula; Liquid drainage between 4 and 8mL: Apply one milliliter of bioactive formula; Liquid drainage greater than 8mL: Apply two milliliters of bioactive formula. The procedure is ambulatory and is performed percutaneously. It is repeated at 7, 30, 60 and/or 90 days, if in these periods of time the cystic lesion persists and fluid is drained.

Intervention code:

Drainage

Injections, Intralesional

Administration, Cutaneous

Ambulatory Surgical Procedures

Intervention keyword:

Bioactive Formula
