[Prostaglandins E in malignant stomach neoplasms].

Prostaglandins E (PGE) levels in gastric neoplasme have been studied radioimmunologically in 84 patients (aged 31-77) with tumors of different stages. A relationship between PGE level and main clinico-morphological features of tumor has been established. PGE concentration was shown to correlate with age, stage, histological pattern of tumor, cell differentiation and tumor infiltration.
