The Effect of Lymph Node Dissection on the Survival of Patients With Operable Gastric Carcinoma

What is the effect of different extents of lymph node dissection (D1, D2, and D3 lymphadenectomy) in patients affected with operable gastric carcinoma?Compared with D1 lymphadenectomy (the most conservative type of lymph node dissection), D2 lymphadenectomy (but not D3) is associated with better disease-specific survival, although a more extended dissection is burdened by a higher postoperative mortality rate.
