If >95% of the tumor is composed of glands then it is classified as being well differentiated, 50%95%% is moderately differentiated, and <50% is poorly differentiated.
Lagidium ahuacaense was the fourth species of the genus Lagidium to be described, after L. peruanum, L. viscacia, and L. wolffsohni of the central and southern Andes, although more species may eventually be recognized within L. peruanum and L. viscacia and L. wolffsohni is poorly differentiated from L. viscacia.
Tumor type was assessed in 162 cases and more than 80% of the cases were poorly differentiated or moderately differentiated adenocarcinoma (Table 1).
The distribution of cytonuclear grade of the DCIS in this UK trial is different to that in other series such as the EORTC 10853 trial; in the latter study, only 40% of cases were poorly differentiated, 28% were moderately differentiated and 32% were well differentiated (Bijker et al, 2001).
Five cases were early invasive OSCC, 22 were well differentiated, 10 were moderately differentiated and 1 was poorly differentiated.
Among the 80 ACs, 27 were well differentiated, 25 were moderately differentiated, and 28 were poorly differentiated.
Of the 113 total colorectal adenocarcinomas examined, 22 were well differentiated, 83 were moderately differentiated, and 8 were poorly differentiated.
Of the 116 esophageal SCC, 31 were well differentiated, 56 were moderately differentiated, and 29 were poorly differentiated.
The distribution of 8% well differentiated, 50% moderately differentiated, and 42% poorly differentiated adenocarcinomas correlates well with a previous series of 55 FMAs [ 39] in which 14% were well differentiated, 60% were moderately differentiated and 27% were poorly differentiated.
Six percent of tumours were well differentiated, 37 % were moderately differentiated, and 13%% were poorly differentiated.
Among the adenocarcinoma cases, 90 were well-differentiated tumors, 130 were moderately differentiated, and 220 were poorly differentiated.
