EOD Regional Nodes

Coding lymph nodes for prostate are based on location.

The regional lymph nodes for prostate are

• Hypogastric
• Iliac, NOS
  • External
  • Internal (hypogastric) (obturator, NOS)
• Pelvic, NOS
• Periprostatic
• Sacral, NOS
  • Lateral (laterosacral)
  • Middle (promontory) (Gerota’s node)
  • Presacral

For path only cases

• Code 000 (no evidence of lymph nodes) may be coded when the only information available is the pathology report, it is a localized cancer (no evidence of extraprostatic extension from the pathology report), and there is no information on lymph nodes.
  
  Note: This instruction is for Prostate ONLY. Do NOT apply this instruction to any other primary site or schema.

See SEER*RSA, Prostate, for the current version of EOD and complete coding instructions for the Prostate schema.
