Collaborative Stage

Note 1: Positive regional lymph nodes (FIGO Stage IIIC) are coded in the CS Lymph Nodes field.
Note 2: Codes 130 and 660: Since "malignant ascites or malignant peritoneal washings" was not specifically categorized in the 1977 Summary Staging Guide, it is unclear to which stage previous cases may have been coded.
Note 3: Liver capsule metastases are coded to 750-780 in the Extension field; liver parenchymal metastases are coded in the Mets at DX field.
Note 4: Both extension to and discontinuous metastasis to any of the following PELVIC organs is considered FIGO Stage II and coded in the range 350-660: adnexae, NOS; bladder, bladder serosa; broad ligament (mesovarium); cul-de-sac; fallopian tubes; parametrium; pelvic peritoneum; pelvic wall; rectum; sigmoid colon; sigmoid mesentery; ureter; uterus; uterine serosa.
Note 5: Both extension to and discontinuous metastasis to any of the following ABDOMINAL organs is considered FIGO Stage III and coded in the range 690-780: abdominal mesentery; diaphragm; gallbladder; infracolic omentum; kidneys; large intestine except rectum and sigmoid colon; liver (peritoneal surface); omentum; pancreas; pericolic gutter; peritoneum, NOS; small intestine; spleen; stomach; ureters.
Note 6: From the AJCC Manual 6th Edition (page 285): "It may be preferable to classify a patient as TX (primary tumor cannot be assessed) if inadequate staging biopsies and/or a lack of peritoneal cytology make it inaccurate to classify the patient with confidence as early stage (Stage T3a/IIIA has not been excluded by adequate staging biopsies)."
