CS Extension: Corpus Uteri; Uterus, NOS: excluding Placenta

Note 1: According to the AJCC, extension to the bowel or bladder mucosa must be proven by biopsy in order to rule out bullous edema.

Note 2: Since "cancer cells in ascites or in peritoneal washings" was not specifically categorized in the 1977 Summary Stage Guide, is unclear to which stage previous cases may have been coded.
