[Clinico-morphological characteristics of light-cell adenocarcinoma of the ovaries].

Clinical and morphological data on 37 observations of a rare neoplasm, clear-cell adenocarcinoma of the ovaries (CAO), are presented. Studies of the microstructure permitted the authors to distinguish 4 histological variants: tubular, papillary, solid, and mixed. Comparison of the data on the three-year survival rate with different histological variants of the tumor in all stages and within stage I revealed a higher survival rate in patients with the tubular variant of CAO which is considered to be more favourable prognostically. The data of 3-year survival rate of all the patients (32.8 +/- 7.9%), and of those in stage I, with the tubular variant (88.9 +/- 10.5%), papillary and mixed variants taken together (23 +/- 11.5%), are presented. In the latter the survival rate is much lower than in the tubular variant of the tumor. The variant of the CAO microstructure should be included into the diagnosis.
