Second malignant neoplasms occuring in survivors of osteosarcoma.
BACKGROUND
Second malignant neoplasms have been noted infrequently in survivors of osteosarcoma treated before 1970.


METHODS
For the above reason, the authors surveyed their patients to determine the actuarial incidence and relative risk of second malignancies among patients treated with adjuvant chemotherapy for osteosarcoma.


RESULTS
Between March 1962 and March 1996, 334 patients received chemotherapy for newly diagnosed primary or metastatic osteosarcoma. Of these patients, 47 presented with metastases, 14 had multifocal osteosarcoma, and 273 had localized disease. Nine patients developed second malignant neoplasms 0.45-17.8 years (median, 6.3 years) after receiving definitive surgery and adjuvant chemotherapy for primary osteosarcoma; 2 of these patients had pulmonary metastasectomies before receiving adjuvant chemotherapy. The second neoplasms comprised two cases of malignant fibrous histiocytoma and one case each of melanoma, glioblastoma multiforme, chondrosarcoma, and carcinoma of the breast: stomach, colon, rectum. The overall 10-year cumulative incidence of second malignancies was 2% +/- 1%; by comparison, this rate was 2% +/- 1% for patients with localized osteosarcoma but was 8% +/- 5% (P = 0.15) for those who presented with metastatic disease.


CONCLUSIONS
Since the advent of successful adjuvant chemotherapy, more patients are surviving primary osteosarcoma; therefore, the number of osteosarcoma patients who develop second malignancies can be expected to increase. Recognition of osteosarcoma patients who are members of families with Li-Fraumeni syndrome may lead to earlier intervention for these individuals.
