[Tumour-host interaction and prognosis in patients with gastric cancer].

The study analyzed the prognostic significance of a group of three histologic markers belonging to intra- and peritumorous stroma as derived from a series of 66 patients with gastric adenocarcinoma operated upon in Craiova CFR General Surgery Clinic. To this end we attempted to uncover any possible correlation between the three stromal parameters represented by type of angiogenesis, peritumorous inflammatory infiltrate and desmoplastic reaction and both the depth of malignant invasion through the gastric wall and the histologic type of gastric cancer. The results of our investigation highlighted that type A2 angiogenesis is displayed mostly by gastric carcinomas with well-differentiated tubular and secretory structure (class 2 Goseky) whereas type A3, angiogenesis is mainly a feature of gastric cancer with a poorly-differentiated tubular morphology (classes 3 and 4 Goseky). Moreover there was no statistically significant correlation between the intensity of inflammatory infiltrate and both the Goseky classes and the depth of neoplastic spread. Finally a clearly desmoplastic reaction was encountered in less than 50% of our patient series and represented almost a characteristic of both poorly-differentiated tubular structured malignancies and serosa invading tumors.
