1 Hereditary ovarian/breast cancers (HOC/HBOC) Chair and Department of Surgical Gynecology and Gynecological Oncology of Adults and Adolescents. Head: Prof. zw. dr hab. n. med. Izabella Rzepka–Górska

2 HOC - SS HBOC (~80%)

3 Definitive criteria for HOC

4 at least 3 relatives with ovarian cancer one of them is I 0 or II 0 relative for two others

5 Criteria for high probability HOC

6 1/ two ovarian cancer diagnosed in I 0 or II 0 (any age)

7 2/ one ovarian cancer (diagnosed in any age) and patients second primary breast cancer or breast cancer diagnosed before the age of 50 years in I 0 or II 0 relatives

8 Clinical characteristics of HOC

9 I group HOC – pedigree criteria (patients with ovarian cancer)

10 II group HOC – patients with ovarian cancer and detected founder mutation of BRCA1 gene

11 Age at diagnosis (of ovarian cancer) HOC - 51,6 yrs HOC (BRCA1+) - 51,44 yrs

12 Age at diagnosis (of ovarian cancer) in Norway HBOC (BRCA1+) - 51,5 yrs Borg et al.

13 Age at diagnosis (of ovarian cancer) 56 - 61 yrs (in general populations)

14 FIGO staging - III 0 & IV 0 (of ovarian cancer) HOC – 86,36% HOC (BRCA1+) – 83,87%

15 FIGO staging - III 0 & IV 0 (of ovarian cancer) in Norway HBOC (BRCA1+) - 81,82% Borg et al.

16 Morphological grading - G3 (of ovarian cancer) HOC – 81,25% HOC (BRCA1+) – 73,91%

17 Morphological grading - G3 (of ovarian cancer) in Norway HBOC (BRCA1+) - 82% Borg et al.

18 Histopathological type - serous (of ovarian cancer) HOC – 86,36% HOC (BRCA1+) – 80,77%

19 Histopathological type - serous (of ovarian cancer) in Norway HBOC (BRCA1+) - 91% Borg et al.

20 BRCA1 (ovarian cancer ) 46 - 50 - III/IV - 3

21 D N A testing

22 IHCC POLAND Head: Prof. dr habil. n. med. Jan Lubi ń ski 16 january 200 7 3718 - BRCA1 Mutations Carriers The largest registry in the world

23 IN POLAND 13.5% of ovarian cancer develop in BRCA1 mutation carriers

24 Frequency of BRCA1 mutations in series of consecutive ovarian cancers from different populations POPULATION Frequency of mutations %n ASHKENAZI JEWISH35,5 27,5 67/189 57/208 POLISH13,549/364 PAKISTANI13,316/120 HUNGARIAN11,110/90 USA8,610/116 CANADIAN7,639/515 FRENCH CANADIAN5,15/99 FINNISH4,711/233 JAPANESE4,03/76 BRITISH3,412/355 NORWEGIAN3,32/60

25 Now we have the question?

26 What we can do with members hereditary cancer families ?

27 S c r e e n i ngS c r e e n i ng

28 1/ Intravaginal USG + CA 125 - beginning 20 - 25(yrs) Interval 6 (months)

29 Female genital tract screening by TV USG detects only 10% of early ovarian cancer NAROD S.A. ONTARIO 1999

30 What yet we can do?

31 2/ we recommend (patients with BRCA mutation carriers) Prophylactic adnexectomy and hysterectomy at the completion of childbearing > 40 yrs of age.

32 Prophylactic operations in our Clinic 1 january 2007 - 125
