[Characteristics of gastric lymph outflow in the presence of an adhesive process].
Under study were some regularities in the formation of gastric adhesions lymph vessels taking into account the pretumor background lesions and age. The study was undertaken on 103 complexes of abdominal organs from person died at the age of 50-94 and from 74 patients operated upon for cancer arising from ulcers and due to chronic gastritis. In cancers caused by ulcers gastric adhesions with adjacent organs were found to be well developed, these occurred prior to ulcer malignant transformation and had an extensive network of lymph vessels being the routes for proliferation of neoplastic cells beyond the boundaries of the organ under unfavourable conditions of their growth in gastric walls due to the presence of scarring tissue in the periphery of ulcer. In cancers arising due to chronic gastritis adhesions would develop at late stages of the disease as a compensatory mechanism in significantly impaired lymphodynamics by the lesion. These were of no practical importance for tumor metastasizing, since a submucous gastric layer, loose and rich in lymph vessels, contributed to prompt tumor invasion of the stomach walls. In aged and senile patients a considerable deformation and reduction of lymph vessels in adhesions and in the stomach walls do not contribute to rapid growth and proliferation of a neoplasm.
