CODE 2   Stage IB

Tumour limited to both ovaries, capsule intact, no tumour on ovarian surface; no malignant cells in ascites or peritoneal washings.

CODE 3   Stage IC1

Tumour limited to one or both ovaries or fallopian tubes with surgical spill.

Stage II Tumour involving one or both ovaries with pelvic extension

CODE 4   Stage IC2

Tumour limited to one or both ovaries or fallopian tubes, with capsule ruptured before surgery or tumour on ovarian surface.

CODE 5   Stage IC3

Tumour limited to one or both ovaries or fallopian tubes, with malignant cells in the ascites or peritoneal washings.

Stage II Tumour involving one or both ovaries with pelvic extension (below pelvic brim)

CODE 6   Stage IIA

Extension and/or implants on uterus and/or fallopian tubes.

CODE 7   Stage IIB

Extension to other pelvic intraperitoneal tissues.

Stage III Tumour involving one or both ovaries with cytologically or histologically confirmed spread to the peritoneum outside the pelvis and/or metastasis to the retroperitoneal lymph nodes.

CODE 8   Stage IIIA1

Positive retroperitoneal lymph nodes only (cytologically or histologically proven).

CODE 9   Stage IIIA1(i)

Positive retroperitoneal lymph nodes only (cytologically or histologically proven), with metastasis up to 10 mm in greatest dimension.

CODE 10   Stage IIIA1(ii)

Positive retroperitoneal lymph nodes only (cytologically or histologically proven), with metastasis more than 10 mm in greatest dimension.

CODE 11   Stage IIIA2

Microscopic extrapelvic (above the pelvic brim) peritoneal involvement with or without positive retroperitoneal lymph nodes.

CODE 12   Stage IIIB

Macroscopic peritoneal metastasis beyond the pelvis up to 2 cm in greatest dimension, with or without metastasis to the retroperitoneal lymph nodes.

CODE 13   Stage IIIC

Macroscopic peritoneal metastasis beyond the pelvis more than 2 cm in greatest dimension, with or without metastasis to the retroperitoneal lymph nodes (includes extension of tumour to capsule of liver and spleen without parenchymal involvement of either organ).

CODE 14   Stage IV

Distant metastases, excluding peritoneal metastases.

CODE 15   Stage IVA
