|
Stage I: tumor confined to ovaries or fallopian tube(s) |
IA: tumor limited to 1 ovary (capsule intact) or fallopian tube; no tumor on ovarian or fallopian tube surface; no malignant cells in the ascites or peritoneal washings |
IB: tumor limited to both ovaries (capsules intact) or fallopian tubes. No tumor on ovarian or fallopian tube surface. No malignant cells in the ascites or peritoneal washings |
IC: tumor limited to one or both ovaries or fallopian tubes, with any of the following: IC1: surgical spill IC2: capsule ruptured before surgery or tumor on ovarian or fallopian tube surface IC3: malignant cells in the ascites or peritoneal washings |
|
Stage II: tumor involves one or both ovaries or fallopian tubes with pelvic extension (below pelvic brim) or peritoneal cancer |
IIA: extension and/or implants on the uterus and/or fallopian tubes/and/or ovaries |
IIB: extension to other pelvic intraperitoneal tissues |
|
Stage III: tumor involves one or both ovaries, or fallopian tubes, or primary peritoneal cancer, with cytologically or histologically confirmed spread to the peritoneum outside the pelvis and/or metastasis to the retroperitoneal lymph nodes |
IIIA1: positive retroperitoneal lymph nodes only (cytologically or histologically proven): IIIA1(i): metastasis up to 10 mm in greatest dimension IIIA1(ii): metastasis more than 10 mm in greatest dimension |
IIIA2: microscopic extrapelvic (above the pelvic brim) peritoneal involvement with or without positive retroperitoneal lymph nodes |
IIIB: macroscopic peritoneal metastasis beyond the pelvis up to 2 cm in greatest dimension, with or without metastasis to the retroperitoneal lymph nodes |
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 tumor to capsule of liver and spleen without parenchymal involvement of either organ) |
|
Stage IV: distant metastasis excluding peritoneal metastases |
IV A: pleural effusion with positive cytology IV B: metastases to extra-abdominal organs (including inguinal lymph nodes and lymph nodes outside of abdominal cavity) |
