Stomach, subtotal gastrectomy: Advanced gastric carcinoma
1. Location : middle third, Center at body and anterior lesser curvature
2. Gross type : Borrmann type 2
3. Histologic type : tubular adenocarcinoma, poorly (solid) differentiated
4. Histologic type by Lauren : intestinal
5. Size : 3x2.5 cm
6. Depth of invasion : invades muscularis propria (pT2)
7. Resection margin: free from carcinoma, safety margin: proximal 1.5 cm, distal 7.5 cm
8. Lymph node metastasis : metastasis to 2 out of 33 regional lymph nodes (pN1), (perinodal extension: absent) (2/33: "3", 2/5; "4", 0/8; "5", 0/2; "6", 0/3; "7", 0/4; "9", 0/3; "8a", 0/3; "11p", 0/2; "12a", 0/1; "4sb", 0/0; "1", 0/2)
9. Lymphatic invasion : not identified
10. Venous invasion : not identified
11. Perineural invasion : not identified
12. Peritoneal cytology : negative
13. AJCC stage by 8th edition: pT2 N1

Gross type을 병리과에서 보만 2형으로 주었습니다. 저는 보만 3형이 적당할 것으로 생각하였습니다. 따지지는 않았습니다. 어짜피 별 상관이 없는 것이므로.
