[The influence of ovarian tumour histopathological diagnosis on prognostic values of the sonomorphological index].
OBJECTIVE
The purpose of the study was to evaluate the helpfulness of sonomorphological index in preoperative diagnosis of ovarian tumours.


METHODS
686 patients diagnosed and treated because of adnexal tumours were analyzed. At the admission day the patient underwent an ultrasonographical examination that stated morphology of tumour using the sonomorphological index (SM).


RESULTS
The sonomorphological index demonstrated high prognostic values: accuracy - 80.6%; sensivity - 86.7%; specifity - 77.0%. During the study, histopathological types of ovarian tumours with the lowest prognostic values were appointed. Among malignant tumours the lowest sensitivity of the test corresponded with: dysgerminoma and folliculoma. Among benign tumours the lowest helpfulness in preoperative diagnosis of ovarian tumours the sonomorphological index demonstrated in following histopathological types: mucinouse cystadenoma and adult teratoma. Particular histopathological diagnosis is the tubo-ovarian abscess--all analyzed cases had a false positive result in the test.


CONCLUSIONS
In all histopathological types of malignant and benign tumours mentioned above, the use of the sonomorphological index require caution. To increase accuracy of preoperative diagnosis based on ultrasonographical examination, additional Doppler examination and also biochemical markers concentration should be considered.
