Abstract

BACKGROUND: The addition of liposomal muramyl tripeptide phosphatidylethanolamine (MTP‐PE) to chemotherapy has been shown to improve overall survival in patients with nonmetastatic osteosarcoma (OS). The authors report the results of addition of liposomal MTP‐PE to chemotherapy for patients with metastatic OS. METHODS: Intergroup‐0133 was a prospective randomized phase 3 trial for the treatment of newly diagnosed patients with OS. The authors compared 3‐drug chemotherapy with cisplatin, doxorubicin, and high‐dose methotrexate (Regimen A) to the same 3 drugs with the addition of ifosfamide (Regimen B). The addition of liposomal MTP‐PE to chemotherapy was evaluated. RESULTS: Five‐year event‐free survival (EFS) for patients who received liposomal MTP‐PE (n = 46) was 42% versus 26% for those who did not (n = 45) (relative risk for liposomal MTP‐PE, 0.72; P = .23; 95% confidence interval [CI], 0.42‐1.2). The 5‐year overall survival for patients who received MTP‐PE versus no MTP‐PE was 53% and 40%, respectively (relative risk for liposomal MTP‐PE, 0.72; P = 0.27; 95% CI, 0.40‐1.3). The comparison of Regimen A with Regimen B did not suggest a difference for EFS (35% vs 34%, respectively; relative risk for Regimen B, 1.07; P = .79; 95% CI, 0.62‐1.8) or overall survival (52% vs 43%, respectively; relative risk for Regimen B, 1.1, P = .75; 95% CI, 0.61‐2.0). CONCLUSIONS: When the metastatic cohort was considered in isolation, the addition of liposomal MTP‐PE to chemotherapy did not achieve a statistically significant improvement in outcome. However, the pattern of outcome is similar to the pattern in nonmetastatic patients. Cancer 2009. © 2009 American Cancer Society.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
