Histopathological grading of ascending aortic aneurysm
2011/10/16 14:27 in Pathology
세상은 넓고 옵세는 많다. Aorta 에 대한 degeneration 부분에 대한 것도 등급을 매겨본 사람이 있다. 1년에 한 번 미만으로 사용하는 grade system.

Criteria for evaluation of therapeutic efficacy
Grade 0: Ineffective
There is no discernible therapeutic effect on cancer tissue or cells.
Grade 1: Slightly effective
Apparently “viable” cancer cells (including cells having eosinophilic cytoplasm with vacuolation and swollen nuclei) account for 1/3 or more of tumor tissue, but there is some evidence of degeneration of cancer tissue or cells.
Grade 1a: viable cancer cells accounting for 2/3 or more of tumor tissue
Grade 1b: viable cancer cells accounting for 1/3 or more, but less than 2/3, of tumor tissue
Grade 2: Moderately effective
Grade 1b: viable cancer cells accounting for 1/3 or more, but less than 2/3, of tumor tissue
Grade 2: Moderately effective
“Viable” cancer cells account for less than 1/3 of tumor tissue, while other cancer cells are severely degenerate or necrotic.
Grade 3: Markedly effective
There are no viable cancer cells evident.
대장암에서 수술전 항암화학요법을 받았을 경우 이에대한 치료 반응 정도를 평가하는 등급은 AJCC 에서도 언급이 되어 있을만큼 일반적으로 받아들여지는 기준이 있다. 하지만, 식도에서는 널리 받아들여지는 기준은 아직 없는 것 같고, 작년 12월에 관련 논문을 찾은 적이 있다.

Fuhrman Grading System
. Grade X (GX): Cannot be assessed
. Grade 1 (G1): Nuclei round, uniform, approximately 10 um in diameter; nucleoli inconspicuous or absent
. Grade 2 (G2): Nuclei slightly irregular, approximately 15 um in diameter; nucleoli evident
. Grade 3 (G3): Nuclei very irregular, approximately 20 um in diameter; nucleoli large and prominent
. Grade 4 (G4): Nuclei bizarre and multilobated, 20 um or greater in diameter, nucleoli prominent, chromatin
clumped

이 Grade에 관한 것을 찾으려고 몇 번을 시도했었는데 드디어 찾았다. :) 가끔씩 Grade III 상태의 태아를 보내는데 좀.. -_-;; 님하..

skin often has a parboiled appearance
Grade I
skin starts to peel
Grade II
peeling may be extensive and red effusion present in the serous cavities
Grade III
the liver is yellowish-brown and the effusions turbid
