In secondary tumors one can often appreciate the pre-existing lesion such as an osteochondroma or enchondroma. Classically, treatment is with curettage and packing with bone chips or polymethylmethacrylate PMMA.

Their surface location and effect on downstream signal transduction cascades make them particularly attractive when designing targeted therapies. See other articles in PMC that cite the published article.

Efficacy of surgery and imatinib mesylate in the treatment of advanced gastrointestinal stromal tumor: However, malignant transformation is far more common in men M: The two recurrences were managed with re-excision and no patient developed distant disease. Muramyl tripeptide phosphatidylethanolamine MTP-PE is a non specific immune modulator that is a synthetic analogue of bacterial cell wall components. Additionally, recent data suggests that a change in the size and signal of the tumor post-chemotherapy may predict local recurrence and survival.
