ABSTRACT
IIIA1: Positive retroperitoneal LNs only (cytologically or histologically proven) IIIA1(i) Metastasis up to 10 mm in greatest dimension IIIA1(ii) Metastasis more than 10 mm in greatest
dimension IIIA2: Microscopic extrapelvic (above the pelvic brim)
peritoneal involvement with or without positive retroperitoneal LNs T3a2-N0/N1-M0 (new literature)
While this change highlights the diagnostic and prognostic importance of nodal evaluation, the therapeutic role of lymphadenectomy (LND) is still evolving. In this chapter, the pattern of nodal involvement and technique for dissection of the retroperitoneum are presented.
