  1. Arithmetic mean and standard deviation of the respective parameters are listed. The results are subdivided by the submitting institutions and by histotype (U, university hospital; H, peripheral hospitals; GP, gastroenterologists. Adeno, adenocarcinomas; squamous, squamous cell carcinomas; other, other histotypes). No significant differences were detected among the three subgroups.
