Question: Why are M & N not detected in pathology staging (pT3aNxMx) after total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy?
In cancer staging, when you see "Nx" and "Mx" in the pathology report, it means these aspects couldn't be fully assessed. The TNM staging system breaks down as follows:

Question: Why are M & N not detected in pathology staging (pT3aNxMx) after total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy?
In cancer staging, when you see "Nx" and "Mx" in the pathology report, it means these aspects couldn't be fully assessed. The TNM staging system breaks down as follows:
• T3a - indicates the size and extent of the main tumor
• Nx - means the lymph node status could not be evaluated
• Mx - means the presence of distant metastasis could not be determined This staging information is typically determined through surgical examination and pathology testing. Sometimes, certain areas cannot be fully assessed during surgery or through available tissue samples, leading to an "x" designation. This doesn't necessarily mean cancer is present in these areas - it simply means a definitive assessment couldn't be made at the time of staging.
