In preclinical studies, the administration of anti-EMP2 monoclonal antibody significantly reduces primary and secondary tumor load, and expression of cancer stem cell markers, and demonstrates benefit of survival that extends beyond cessation of treatment.
Because there is a chance of secondary tumor development, the decision to surgically excise the lesion or closely follow for transformation is controversial.
