Ovary Cancer(FIGO 1985)

Stage
I	Growth limited to ovaries
	IA	Growth limited to one side ovaries; no ascites. No tumor on external surface; capsules intact
	IB	Growth limited to both ovaries; no ascites. No tumor on external surface; capsules intact
	IC	Tumor either IA or IB but with tumor on surface of one or both ovaries;or with capsule ruptured; or with ascites containing malignant cells, or with positive peritoneal washings
II	Growth involving one or both ovaries with pelvic extension.
	IIA	Extension and/or metastasis to the uterus and/or tubes.
	IIB	Extension to other pelvic tissues.
	IIC	Tumor either Stage IIA or IIB, but with tumor on surface of one or both ovaries; or with capsule ruptured; or with ascites containing malignant cells, or with positive peritoneal washings.
III	Tumor involving one or both ovaries with peritoneal implants outside pelvis and/or positive retroperitoneal or inguinal nodes. Superficial liver metastasis equals Stage III.
	IIIA	Tumor grossly limited to true pelvis with negative nodes, but with histologically confirmed microscopic seeding of abdominal peritoneal surfaces.
	IIIB	Tumor of one or both ovaries with histologically confirmed implants to abdominal peritoneal surfaces, none exceeding 2 cm in diameter Nodes are negative.
	IIIC	Abdominal implants >2 cm in diameter and/or positive retroperitoneal or inguinal nodes.
IV	Growth involving one or both ovaries with distant metastasis. If pleural effusion present, must be positive cytology to assign a case to Stage IV. Parenchymal live metastasis equals Stage IV.

Notes

To evaluate the impact on prognosis of the different criteria for assigning cases to Stage IC or IIC, it would be of value to know: 1) if rupture of the capsule was a) spontaneous or b) caused by the surgeon, or 2) if the source of malignant cells detected was a) peritoneal washings or b) ascites.
