title: [Prognostic factors for the definition of the extent of lymphadenectomy by the early gastric cancer].
abstract: The predictive role of submucosal invasion and metastatic spread to local lymph nodes at early gastric cancer was analyzed. Material from 32 patients was morphologically and immunohistochemically analyzed. The prognostic value of the depth of invasion, tenascin and positive MMP2 and MMP9 staining, proliferative activity and microvascular solidity in the lesion were studied. Watch lymph nodes were detected in 22 patients with the diagnosed early gastric cancer. The method is appropriate only by early cancer and in combination with other macro- and microscopic factors. Its' efficacy was 100% in the group of the early cancer (n=15), whereas in the group with the locally spread cancer the sensitivity, accuracy and specificity were 76, 71 and 100%, respectively. Though larger series are necessary to make definite conclusions about the predictive value of watch nodes in gastric cancer.
