Intracutaneous and Intravesical Immunotherapy With Keyhole Limpet Hemocyanin Compared With Intravesical Mitomycin in Patients With Non–Muscle-Invasive Bladder Cancer: Results From a Prospective Randomized Phase III Trial

Abstract

KLH had a different safety profile and was inferior to MM in preventing NMIBC recurrences. KLH tended to be more effective than MM in preventing progression. More research is needed to clarify the immunologic effects of KLH and the effects of KLH on progression.
