PANCREAS HEAD CANCER (PDAC)

II. Histopathologic Diagnosis
(1) Histologic type: ductal adenocarcinoma
(2) Histologic Grade: G2 (moderately differentiated)
(3) Tumor size: 4.8x3.5 cm (microscopic measurement)
(4) T3: Tumor extends beyond the pancreas but without involvement of the celiac axis or the superior mesenteric artery
(5) Extension into common bile duct (absent), duodenum (present), peripancreatic (retroperitoneal) soft tissue (present) {T3 in JPS}
(6) N1: Regional lymph node metastasis (12/25)
(7) cM0: Clinically No distant Metastasis
(8) Involvement of superior mesenteric vein: present (tumor invasion into vessel intima) [I]
(9) Margin status
- SMA side margin: negative but very close (safety margin: 200 §­)[K]
- Portal vein side margin: negative but very close (safety margin: 500 §­)[I]
- Pancreas neck margin: negative (safety margin: 2.4 cm)
(10) Perineural and neural invasion: present
(11) Lymphovascular invasion: present

[Additional note]
(1) Proportion: well to moderately (75 %) / poorly (25 %) differentiated
(2) Tumor Pattern Score (PS): 5(2+3)
(3) Mucoepidermoid-like feature: absent
(4) Stromal reaction: desmoplasia (2) / inflammation (2) / myxoid degeneration (0)
(5) Tumor necrosis: absent
(6) Nuclear pleomorphism: moderate
(7) Mucin production: irregular
(8) Chronic cholecystitis, autolysis
(9) ICD code (ICD-O): M8500PDAC
(10) Tumor Regression grade: Not applicable

[rR1]: grossly negative but microscopically positive resection margins due to very close to retroperitoneal(portal vein /SMA side margin)

AJCC stage (2010, 7th ed) Stage IIB T3 N1 M0
