title: [Histological subtypes of ovarian carcinoma and their importance for clinical prognosis].
abstract: Ovarian cancer is one of the most common and most lethal cancers. For Bulgaria (2012) it occupies third place in the structure of gynecological malignancies with a share of 22.6 percent, while regarding mortality is at first place with 35.7 percent. New cases are 838 with crude incidence 22.3 x 10(5), and the deaths are 463 with crude mortality 12.3 x 10(5). Ovarian tumors, even when they are of the same histological type clearly differ in their cellular differentiation, molecular characteristiques and subsequently in their biological behavior. In this review, we discuss the frequency origin, morphology and molecular characteristiques of the five major subtypes of ovarian cancer--serous low and high grade, mucinous, endometroid and and clear cell. The role of different risk and prognostic factors for the efficiency of the treatment and control of disease been discussed.
