Intervention Associated With Decreased Risk
Based on solid evidence, at least 1 year's use of oral contraceptives containing estrogen and progesterone decreases endometrial cancer risk, proportionate to duration of use. This benefit lasts at least 15 years after cessation.[1,2]
Magnitude of Effect: Use of oral contraceptives...
This summary focuses on high-grade sarcomas and low-grade tumors that present special problems in the pediatric and adolescent population, including desmoid tumor and infantile fibrosarcoma. For many low-grade STSs, surgical resection is curative and there is no need for additional therapy.
Liposarcoma—myxoid or well-differentiated.
Extraskeletal chondrosarcoma (mesenchymal and other variants).
Desmoid tumor (also called aggressive fibromatosis).a
Undifferentiated sarcoma; sarcoma, not otherwise specified (NOS).
a Not a high-grade tumor; b The category of fibrosarcoma can be inclusive of fibrosarcomatous differentiation in dermatofibrosarcoma protuberans; c Cutaneous angiosarcoma may be difficult to stage using the American Joint Committee on Cancer system.
