Abstract:
We report a case of ovarian metastasis after complete response of colon cancer. A 55-year-old woman underwent a sigmoidectomy for sigmoid colon cancer with hepatic metastasis and para-aorta lymph node metastasis. After the operation, the patient was given chemotherapy with bevacizumab+mFOLFOX6. Nine months after the operation, the patient was judged to have achieved complete response. Thirteen months after the operation, right ovarian tumor was found and bilateral oophrectomy, hysterectomy and omentectomy were performed. Histopathologically the ovarian tumor was metastasized from colonic cancer. After the second operation, the patient was given chemotherapy with bevacizumab+FOLFIRI. At present, the patient remains disease-free for 6 months after the ovarian operation.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
