Epithelial Ovarian Carcinoma Types and the Coexistence of Ovarian Tumor Conditions

Table 2

Specific diagnoses of 75 consecutive tissue specimen from PALGA Nijmegen 2007 according to age.

Diagnosis	All ages	<55 yr		≥55 yr
	𝑛	𝑛	%	𝑛	%
Total	75	48	64.0	27	36.0
Ovarian carcinoma	25*	8	32.0	17	68.0
Borderline malignancies	6	4	66.6	2	33.3
Adenoma	15	12	80.0	3	20.0
Tumor-like conditions**	29	24	82.8	5	17.2

*4 patients (16.0%) showed coexisting epithelial ovarian tumor conditions.
**tumor-like conditions: simple cysts, endometriotic cysts, inclusion cysts.
Coexisting epithelial ovarian carcinoma conditions: (4 + 6 + 15 + 29)/75 = 72%.
Chi-square = 17.225, df = 3, 𝑃-value = 0.001.
