TEM으로 치료하였던 rectal GIST입니다.


Rectum, trans-anal endoscopic microsurgery:
. Gastrointestinal stromal tumor of very low risk of malignant potential by proposed modification for adjuvant therapy (2008), none risk (0 %) of progressive disease by Miettinen (2006) :
1) tumor size: 1.4x1.2x0.4 cm
2) mitosis: 3/50 HPF (high powered fields)
3) histological type: spindle
4) necrosis: absent
5) cellularity: intermediate
6) cellular atypia: mild
7) invasion into mucosa: absent
8) resection margin involvement: absent
. Pho-H-H3: Positive in less than 5% of tumor cells
. C-kit : Positive
. DOG1 : Positive

제 전공은 아니지만... 이렇게 작은 GIST는 follow up 하면 어떤가 생각해 보았습니다.
