J. Zwart et al., 5-YEAR SURVIVAL IN PATIENTS WITH ENDOMETRIOID CARCINOMA OF THE OVARY VERSUS THOSE WITH SEROUS CARCINOMA, European journal of gynaecological oncology, 19(3), 1998, pp. 225-228
Background: Ovarian carcinoma is the most deadly of gynecologic malign
ancies. Controversy exists as to whether different histologic types ha
ve a different prognosis. The goal of this study was to determine whet
her patients with endometrioid carcinoma of the ovary have a different
prognosis than patients with serous carcinoma. Methods: Available rec
ords for all patients on the gynecologic oncology service with epithel
ial ovarian carcinoma from January 1, 1981 through December 31, 1989,
were reviewed. Patients with endometrioid ovarian carcinomas were marc
hed with patients with serous carcinoma with regards to age, grade, st
age, and level of cytoreduction. Results. Forty-two patients were stud
ied by matching 21 patients with endometrioid carcinoma with 21 patien
ts with serous carcinoma. The 5-year survival of the 21 patients with
endometrioid carcinoma was 61.9% while the 5-year survival was 71.4% i
n the patients with serous carcinoma (P=0.22). Of the patients diagnos
ed with endometrioid carcinoma, the mean survival was 57 months versus
a mean survival of 69 months in patients with serous carcinoma (P=0.3
0). Estrogen receptor levels were not statistically significantly diff
erent between the two groups (P=0.108); however, progesterone receptor
levels did prove to be statistically significantly different (P<0.001
). Conclusions: When patients with endometrioid and serous tumours of
the ovary are matched for age, grade, stage and level of cytoreduction
, there is no difference in either 5-year survival or length of surviv
al.
