[Normal value of the number of lymph nodes in the epigastrium. An anatomic study for lymphadenectomy in stomach cancer].

The number of regional lymph nodes relevant for lymphadenectomy in gastric cancer was investigated in an autopsy study. In group N1-16 as described by JRSGC on the average 43 lymph nodes were found (range 25 to 64 lymph nodes). For group N1-11 (R1 and R2 resection, compartments I and II respectively) 27 lymph nodes were found on the average (range 17 to 44 lymph nodes). The results differed considerably in total number as well as within each single group and in the groups N1-16/N1-11. These results can be taken as statistical standard values.
