Success rate of organoid culture and derived organoid lines from each histologic subtype of ovarian tumour.

	Number of cases	Number of successful primary organoid culture	Success rate of primary organoid culture (%)	Number of derived organoid lines
HGSC	10	9	90	3
EM	5	3	60	3
CCC	10	10	100	9
MC	0	0	0	0
MBT	3	3	100	2
Others	7	3	43	1
Total	35	28	80	18

HGSC high-grade serous, EM endometrioid, CCC clear cell, MC mucinous, MBT mucinous borderline tumour

Others include dysgerminoma, thecoma, serous cystadenofibroma, carcinosarcoma, and fibroma. Organoid line was defined as an organoid that could be made from a single cell culture and for which a serial passage was successful for four times.
