Polytomous diagnosis of ovarian tumors as benign, borderline, primary invasive or metastatic: development and validation of standard and kernel-based risk prediction models
BACKGROUND Hitherto, risk prediction models for preoperative ultrasound-based diagnosis of ovarian tumors were dichotomous (benign versus malignant). We develop and validate polytomous models (models that predict more than two events) to diagnose ovarian tumors as benign, borderline, primary invasive or metastatic invasive. The main focus is on how different types of models perform and compare....
متن کاملDNA Cytometry and Nuclear Morphometry in Ovarian Benign, Borderline and Malignant Tumors
BACKDROUND Ovarian carcinoma is a leading cause of death in gynecological malignancy. Ovarian surface epithelial serous and mucinous tumours are classified as benign, borderline, and malignant. The identification of borderline tumours most likely to act aggressively remains an important clinical issue. AIM This work aimed to study DNA ploidy and nuclear area in ovarian serous and mucinous; be...
متن کاملp14 expression differences in ovarian benign, borderline and malignant epithelial tumors
BACKGROUND Abnormalities in tumor suppressors p14, p16 and p53 are reported in several human cancers. In ovarian epithelial carcinogenesis, p16 and p53 show higher immunohistochemical staining frequencies in malignant tumors and are associated with poor prognoses. p14 was only analyzed in carcinomas, with conflicting results. There are no reports on its expression in benign and borderline tumor...
متن کاملMutant epidermal growth factor receptor in benign, borderline, and malignant ovarian tumors.
PURPOSE Dysfunction of the epidermal growth factor (EGF) complex is essential to the growth and development of many human tumors. Overexpression of the EGF receptor (EGFR) is a characteristic finding in a considerable number of solid tumors and often signalizes poor prognosis. There is a major disagreement among researchers about both the frequency and possible clinical importance of EGFR overe...
متن کاملRisk factors for benign, borderline and invasive mucinous ovarian tumors: epidemiological evidence of a neoplastic continuum?
OBJECTIVE Some molecular and histological evidence suggests that mucinous epithelial ovarian cancers develop via a sequence from benign tumor through borderline tumor to invasive cancer. Such a sequence would predict some shared risk factors between the different tumor types. To investigate this, we examined risk factors for benign, borderline and invasive mucinous ovarian tumors. METHODS A p...
