Medications for Malignant Perivascular Epithelioid Cell Tumor
Other names: Malignant Perivascular Epithelioid Cell Neoplasm; PEComa
Malignant Perivascular Epithelioid Cell Tumors (PEComas) are a rare and aggressive form of soft-tissue sarcomas.
PEComa is defined by the World Health Organization as 'mesenchymal tumors composed of distinctive cells that show a focal association with blood-vessel walls and usually express both melanocytic and smooth muscle markers'.
Malignant PEComas have a strong female predominance and may arise in almost any body site, including the uterus, retroperitoneum, lung, kidney, liver, genitourinary, and gastrointestinal tract.
Malignant PEComas have been shown to frequently harbor mutations in the TSC1 and/or TSC2 genes that result in the activation of mTOR pathway. Abnormally activated mTOR sends signals that encourage tumor cells to grow, metastasize, and invade new healthy tissues.
Fyarro (sirolimus protein-bound particles for injectable suspension) (albumin-bound)) is the first and only FDA approved therapy for the treatment of malignant PEComa. It is a targeted therapy that works to slow tumor growth by inhibiting mTOR.

Pregnancy Category
A
Adequate and well-controlled studies have failed to demonstrate a risk to the fetus in the first trimester of pregnancy (and there is no evidence of risk in later trimesters).
B
Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women.
C
Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use in pregnant women despite potential risks.
D
There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use in pregnant women despite potential risks.
X
Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use in pregnant women clearly outweigh potential benefits.
