This complementary and alternative medicine (CAM) information summary provides an overview of the use of cartilage as a treatment for people with cancer. The summary includes a brief history of cartilage research, the results of clinical studies, and possible side effects of cartilage use.
This summary contains the following key information:
Bovine (cow) cartilage and shark cartilage have been studied as treatments for people with cancer and other medical conditions for more than 30 years.
Chemotherapy (if the monoclonal [or myeloma] protein [M protein] increases and other evidence of symptomatic multiple myeloma occurs).
About 25% of patients have a serum and/or urine M protein; this should disappear following adequate radiation therapy to the lytic lesion.
The survival rate of patients with isolated plasmacytoma of bone treated with radiation therapy to the lesion is greater than 50% at 10 years, which is much better than the survival rate of patients with disseminated multiple myeloma.
Most patients will eventually develop disseminated disease and require chemotherapy; almost 50% of them will do so within 2 years of diagnosis.[2,3] However, patients with serum paraprotein or Bence Jones protein, who have complete disappearance of these proteins after radiation therapy, may be expected to remain free of disease for prolonged periods.[2,4] Patients who progress to multiple myeloma tend to have good responses to chemotherapy with a median survival of 63 months after progression.[2,4]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with isolated plasmacytoma of bone. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
