Other neuroendocrine markers have been reported positive also
Neuroendocrine cells are positive with both argentaffin and argyrophil stains
Immunohistochemistry is not particularly useful for these distinctionsn
DSS = Disease Specific Survival
Entries marked with * represent only 1 or 2 cases
Stage IIA represents invasion of muscularis propria without node involvement
Stage IIIB represents node involvement without metastasis
