[Prognostic significance of sinus histocytosis of the regional lymph nodes in stomach cancer].

A comparative study was made on different morphological pictures of the sinuses of the regional lymph nodes in gastric cancer patients with T1--4N0M0 with a 5-year survival, also the influence of age, depth of invasion, size and histological structure of the tumor on sinus histiocytosis was studied. Marked sinus histiocytosis, contrary to sinus fibrosis, was found to be a favourable prognostic sign. Sinus histiocytosis is influenced in a somewhat directly proportional way by the tumor size and histological differentiation. The given material rendered impossible to reveal any effect of age and depth of tumor invasion on sinus histiocytosis.
