[Prognostic and therapeutic value of D2 lymphadenectomy in the treatment of gastric cancer: experience of an Italian team].
Recently, the incidence of gastric cancer and the related percentage of mortality have been decreasing world-wide, especially in the industrialised countries. Surgery has commonly been opted for as primary treatment of this disease. However, the optimal extent of surgical intervention is still debated. Japanese surgeons have been the pioneers of perigastric and celiac tripod lymphadenectomies in an attempt to improve long-term survival and the postoperative disease-free period. In recent years, D2 resection has been compared with D1 resection, which consists in excision of the stomach along with its locoregional nodes. From March 2002 to January 2007, 70 interventions for gastric cancer were performed at the VII Division of General Surgery of the Second University of Naples. All patients underwent excision of the lymph nodes from stations 1 to 6 (D1) combined with excision of stations 7 to 12 (D2). In 32 cases (45.7%) there were no metastatic lymph nodes (NO), in 28 patients (40%) 1 to 6 nodes proved metastatic (N1), and in 10 cases (14.3%) from 7 to 15 nodes were metastasised (N2). The incidence of metastatic lymph nodes was 54.3% and the prevalence 13.6%. Metastatic lymph nodes were found mostly in T3 (15/24) and T4 (14/20) stage tumours rather than in T1 (3/12) and T2 (6/14) neoplasms. Two patients (2.86%) died within 60 days of the intervention. The overall postoperative morbidity and mortality rates were 21.43% and 2.86%, respectively. D2 gastrectomies without pancreatic resections present distinct advantages in terms of long-term survival and are associated with postoperative morbidity and mortality rates which are similar to those obtained after D1 node resection.
