Overview
• FBW7/CDC4 is a family of genes• Tumor suppressor• Directly binds to cyclin E• Mutated in about 16% of endometrial cancers

Endometrial Cancer
• Endometrium- lining of the uterus
• Typically occurs within a few decades of menopause
• 49,560 new cases in 2013

Treatments
• Surgery– Hysterectomy along with removal of ovaries,
fallopian tubes, and lymph nodes– Helps stage the cancer
• Chemotherapy– Taxol
• Radiation• Potential Treatments– Cdk2 inhibitors

Prognosis
• 1 year survival rate– 92%
• 5 year survival rate if cancer has not spread– 95%
• 5 year survival rate if cancer has spread– 23%
