Grade of infiltration by pancreatic carcinoma.

Surgical procedure	No. of patients	Grade 0, n (%)	Grade 1, n (%)	Grade 2, n (%)
PD	91	21 (23)	68 (75)	2 (2)
TP	3	0	3 (100)	0
DP	46	13 (28)	31 (68)	2 (4)
Total	140	34 (24)	102 (73)	4 (3)

Retropancreatic infiltration was classified into 3 grades. Grade 0 (carcinoma confined within the parenchyma) was found in 22, 28 and 24% of pancreatoduodenectomy (PD), distal pancreatectomy (DP) and total patients, respectively. Grade 1 (infiltration beyond the parenchyma but within the fusion fascia) was found in 76, 68 and 73% of PD, DP and total patients, respectively. Grade 2 (infiltration of retroperitoneal tissues beyond the fusion fascia) was found in 2, 4 and 3% of PD, DP and total patients, respectively. TP, total pancreatectomy.
