[Hereditary ovarian cancer: summary of 5 years of experience].
In 1992 the first Hereditary Cancer Center in Poland has been organized in Szczecin.


METHODS
One of its goals is application of appropriate management in families with hereditary ovarian cancer. The aims of our program include studies of: incidence, clinical characterization, DNA diagnostic tests and efficiency of screening for early detection of hereditary ovarian tumors in North-West Poland.


METHODS
Our program includes 234 families with 258 cases of ovarian cancers.


RESULTS
Site-specific familial aggregation of ovarian cancer was diagnosed in 16 (6.84%) families, breast-ovarian cancer syndrome in 27 (11.54%), Lynch II syndrome in 5 (2.14%) families, undefined cancer family aggregation in 12 (5.13%) families, sporadic ovarian cancers diagnosed age of 44 in 56 (23.93%) families and other sporadic ovarian cancers in 118 (50.4%). In 17 patients with ovarian cancer from families with breast-ovarian cancer syndrome constitutional BRCA-1 gene mutations were studied by sequencing DNA on automated sequencer of PCR products for all 24 exons. In 1 patient constitutional mutation in exone 11 was detected. We found also multiply polymorphic changes. 124 women-members of 116 families with diagnosed hereditary predisposition for ovarian cancer have been studied for asymptomatic tumors by intravaginal USG and evaluation of CA 125 marker every 6 month beginning from 20-25 years of age. Up to now we found 5 cases of benign serous cystadenomas, 3 cases of cystadenomas of borderline malignancy and 1 cases of serous cystadenocarcinoma.


CONCLUSIONS
It seems, that particular surveillance program in women from families with hereditary cancers can be the effective way of detection of early ovarian tumors. Clinical characterization of hereditary ovarian cancers in North-West Poland and other countries is similar.
