[Multivariate analysis of significance of prognostic factors of immunological response and stomach tumor growth]

Significance of prognostic factors of immunological response, tumor growth and age was investigated in 708 patients with stomach cancer. Such factors as T-cell immunological response, functional status of lymph nodes and localization on either the greater or lesser curvature of the stomach were identified as the most significant while T-cell immunological response, tumor size and number of involved lymph nodes appeared less significant but more harmful as far as survival was concerned. No significant correlation between pattern of growth, depth of invasion, age and local immunological response, on the one hand, and survival, on the other, was established.
