title: [Clinicopathological characteristics of hereditary ovarian cancer syndrome].
abstract: OBJECTIVE
  To explore the clinicopathological characteristics of hereditary ovarian cancer syndrome (HOCS).
  
  
  METHODS
  From Jan. 2000 to Jan. 2007, among 580 cases of primary ovarian cancer, 42 cases (hereditary group), who had a positive family history of ovarian cancer and met the diagnostic criteria of HOCS, were analyzed retrospectively. One hundred cases without a family history of ovarian cancer were enrolled randomizely as control group (sporadic group).
  
  
  RESULTS
  The incidence of HOCS was 7.2% (42/580). Forty-two cases associated tumors affected at least 2 successive generations in 31 families and affected 1 generation in 8 families. Eighty-seven percent (27/31) was from maternal lineage, while 13% (4/31) from paternal lineage. Earlier age of onset was significantly difference between two groups [(49 +/- 10) years vs. (55 +/- 10) years, P < 0.05]. There were 90% belong to serous adenocarcinoma in the hereditary group, while 84% in the sporadic group. There was statistical difference in the proportion of mucinous adenocarcinoma (0 vs. 11%, P < 0.05). The most common clinical manifestations were abdominal distention and anorexia (64% vs. 70%, P > 0.05), International Federational of Gynecology Obstetrics (FIGO) stage III (62% vs. 63%, P > 0.05) between two groups. Fourteen cases (33%,14/42) were previously untreated in the hereditary group, while 40 cases (40%, 40/100) in the sporadic group. There were 15 cases (36%, 15/42) underwent secondary surgery and 15 cases (36%, 15/42) underwent third surgery or more in hereditary group, while 50 cases (50%,50/100) and 27 cases (27%, 27/100) in the sporadic group. The mean number of chemotherapy cycles received in two groups was 13.3 and 11.8 (P > 0.05). The 3-year and 5-year survival rate in hereditary group were 73.6% and 54.9% respectively, compared with 47.4% and 21.2% (P < 0.05) in sporadic group.
  
  
  CONCLUSIONS
  Hereditary ovarian cancer mostly from maternal lineage are featuring in early age of onset, serous adenocarcinoma, advanced stage (stage III), and better prognosis after the comprehensive treated by cytoreductive surgery plus with chemotherapy.
