In Ovo Progression of Borderline Ovarian Tumors

Abstract

Objective: Borderline ovarian tumors (BOTs) are generally considered to be non-invasive tumors with low malignancy potential. However, studies show that BOTs have the ability to progress to low-grade carcinomas and gain the potential to invade surrounding tissue and to metastasize. Here, we investigate whether a patient derived serous BOT (SBOT) could progress in low-grade serous carcinoma (LGSC) through in vitro and in ovo characterization. Methods: Ovarian cancer cell line from a SBOT, named OCAM, were isolated and characterized by PCR, migration assay and chick chorioallantoic membrane (CAM) assay. Results: OCAM cells express carcinoma characteristics and form a tumor in CAM. Moreover, OCAM cells get into membrane of chicken suggesting invasive properties. Conclusion: SBOTs could a precursor of LGSC involving consequences in adaptation of treatment provided by clinician
