title: [Importance of extensive lymphadenectomy in relation to the extent of metastatic lymph node involvement in patients with gastric carcinoma surgery].
abstract: BACKGROUND
  Formation of lymphatic metastasis is an important prognostic factor in treatment of gastric carcinoma. In this paper we would like to point to the importance of systematic lymphadenectomy in regard to extent of metastatic lymph node involvement in patients with gastric carcinoma.
  
  
  METHODS
  This investigation included 114 patients with diagnosis of gastric carcinoma undergoing systematic lymphadenectomy. We analyzed metastatic lymph node involvement considering: 1. tumor localization; 2. histopathologic type; 3. depth of tumor invasion; 4. extent of lymph node resection; 5. stage of disease.
  
  
  RESULTS
  In the course of this study, 2100 lymph nodes were extracted by systematic lymphadenectomy (18.42 lymph nodes per patient on average). Out of this number, about 27% of lymph nodes were involved with metastasis, and 60% of positive lymph nodes belonged to the first, 25.7% to the second, 10.2% to the third and 3.8% to the fourth drainaged group. The most frequent localization (over 56%) of tumors was the distal third region of stomach. Histopathologically, most common type of carcinoma was intestinal carcinoma, with metastasis in first and second drainage group. A great number of patients have tumors with infiltration of the serosa. Those patients had metastases in lymph nodes in over 42%. Most patients (58%) belonged to IV stage of disease and presented with highest number of involved metastatic lymph nodes in all drainage groups.
  
  
  CONCLUSIONS
  In our patients high metastatic involvement of all four drainage groups of lymph nodes was established. Up to date standard lymphadenectomy (D1) which has been performed increased the length of survival of these patients.
  
  
  CONCLUSIONS
  By systematic lymphadenectomy we removed a great number of metastatic lymph nodes with beneficial effect on survival of patients with gastric carcinoma.
