Although our fuzzy gene signatures could accurately distinguished grade 1 from grade 3 tumors and separated grade 2 tumors in grade 1 like or grade 3 like, we defined an indecision zone that scored arbitrarily between 48 and 52%, due to the equivocal gene expression grade profile of these patients.
Moreover, the pterygia were graded according to the system used by [ 12]: grade 1 (atrophic: episcleral vessels under the body of the pterygium are not obscured and clearly distinguished), grade 3 (fleshy: episcleral vessels totally obscured) and grade 2 (intermediate: all other pterygia not falling into these 2 grades).
This data could be used to diagnose PHNETS and distinguish grade 1 and 2 tumors from grade 3 tumors, which typically show multiplicity and central necrosis.
Distinguishing grade 1 chondrosarcoma from grade 2 chondrosarcoma is critical both for planning the surgical procedure and for predicting the outcome.
Clinically, distinguishing grade II from grade III gliomas is very important because the prognoses for patients with grade II gliomas are significantly better than for patients with grade III gliomas [ 22].
Our study suggests that testing for the presence of five genes may not only help clinicians to distinguish grade 1 from grades 2 4 ulcers but will also predict wound outcome.
>>> -wrap-foot> computedtomographyaphy, MRI magnetic resonance imaging, PPV positive predictive value Although several studies have reviewed the differentiation criteria of grade 1 chondrosarcoma from enchondroma [ 13, 16, 18, 20– 24], distinguishing grade 2 chondrosarcoma from grade 1 chondrosarcoma has hardly been discussed.
Thus the clinically defined groups appear to be internally consistent in distinguishing grades of severity.
Based on the presence or absence of malignant features: cell density, nuclear atypia, mitosis, microvascular proliferation, and necrosis, the WHO classification distinguishes grades I, II (LGG), III (anaplastic), and IV (glioblastomas, GBM) [ 2].
A molecular correlate of the Gleason grade was reported where grade 3 could be distinguished from grades 4 and 5 by gene expression, whereas grades 4 and 5 were indistinguishable by gene expression [ 1].
Moreover, histology Grades III and IV have shorter survival following diagnosis of glioma than Grade II; and Grade IV, which has almost 100% mortality within 5 years of diagnosis, is also distinguished from Grade III.
