A substantial proportion of patients have lymph node positive disease in the presacral and retroperitoneal regions, including some with isolated and/or solitary lymph node involvement. While the limited positive lymph node burden in these templates suggests a potential therapeutic role for extending the anatomical boundaries of lymph node dissection, patient survival was poor. Extended lymph node dissection provides important staging information but to our knowledge the therapeutic benefit has yet to be definitively proved.
