Advanced gastric cancer and prognosis

The morphological features of 158 gastric carcinomas were analyzed in an attempt to identify patterns best correlated with prognosis. To this end, the depth of infiltration, vascular invasion, intra- and perineoplastic lymphocytic infiltrate, lymph node metastases and number of metastatic lymph nodes were evaluated according to the several classifications for advanced gastric cancer. A good correlation between prognosis and histological features of malignancy were observed, as well as different five-year survival rates for Mulligan, Lauren and Ming histotypes However, when the influence of each single morphological criteria of malignancy was examined, these differences disappeared for Mulligan and Lauren histotypes. On the other hand, the better prognosis for Ming expanding type carcinomas appeared unrelated to any individual feature of malignancy. © 1985 Springer-Verlag.
