PG - 2819-25 AB - BACKGROUND: The different clinical evolution of gastric adenocarcinomas with the same clinico-pathologic characteristics prompted the authors to investigate the prognostic significance of different biological markers. METHODS: One hundred twenty-six preoperative cancer gastric biopsies, selected according the stage evaluated after following gastrectomy, were examined for DNA content by means the static cytometry, proliferating cell nuclear antigen (PCNA), p53 mutation, apoptosis by immunohistochemistry and karyotype using fluorescence in situ hybridization (FISH) techniques. RESULTS: The gastric cancers, ail belonging at stage III, were adenocarcinomas histologically typed as: 26 well differentiated (G1), 45 moderately differentiated (G2), 43 poorly differentiated (G3) and 12 of undifferentiated type with signet-ring cells. The tumours showed a prevalence of diploidy (68%), a mean PCNA-LI of 4.8%, trisomy of chromosome 7 in 40% of the cases, low presence of apoptosis (30%) and p53 mutation (17%). Only apoptosis was significantly correlated to histological diagnosis (p = 0.009). A multivariate analysis showed that the DNA content and PCNA-LI were the only independent prognostic markers for survival (p = 0.005 and p = 0.0002 respectively). CONCLUSIONS: The evaluation of these two biological variables, especially of the PCNA index, on gastric cancer biopsies may be useful in predicting the aggressiveness of each tumor and in identifying patients in need of additional perioperative therapies.
