[Typical and non-typical lymphogenic spread of XXXX (author's transl)].

@entity1 @entity5 @entity189 @entity3 @entity356
Incidence and distribution of lymph node @entity3 were examined in 100 gastrectomy specimens with 104 primary @entity356 . Special emphasis was placed on the correlation with the location of the @entity5 and its size as well as the depth of infiltration and the @entity5 histology. @entity189 with a diameter of up to 6 cm had lymph node @entity3 while this was the case in 83% of larger @entity5 . Infiltration of the muscularis propria only was associated with a 23% incidence of lymphogeneous @entity3 . This figure rose to 75% if the @entity5 reached the subserosa. @entity189 of the diffuse (Lauren) or infiltrating (Ming) type show @entity3 more frequently (83% and 81% respectively) than those of the intestinal or expansive type (58%). In addition, several regions of lymphatic drainage are more frequently involved with the diffuse type. In only 2 @entity1 (2% of all @entity1 or 3% of the @entity1 with lymphogeneous @entity3 ) skipping of lymph nodes could be observed. In all other @entity1 distant lymph nodes showed @entity3 only if the perigastric nodes next to the @entity5 were involved also. These findings support a differentiated, stage- and histology-dependent surgery.
