Is celiac axis resection justified for T4 pancreatic body cancer?

The clinical impact of the distal pancreatectomy with en-bloc celiac axis resection for locally advanced pancreatic body cancer remains unclear. We reviewed the records of 13 patients who underwent distal pancreatectomy-celiac axis resection between 1991 and 2009, 58 patients who underwent distal pancreatectomy for pancreatic body cancer involving major vessels, the extrapancreatic neural plexus or other organs (T4 according to the Japanese stage classification) between 1991 and 2009, and 24 patients with unresectable locally advanced pancreatic cancer without distant metastases (unresectable group) between 2001 and 2009. The clinicopathologic factors and overall survival among the 3 groups were compared. The distal pancreatectomy-celiac axis resection group was associated with a significantly higher incidence of morbidity (92% vs 60%, P = .03) and positive surgical margins (69% vs 26%, P = .003) than the distal pancreatectomy group; however, no survival difference was found between the 2 groups. No survivor has lived more than 3 years after operation in the distal pancreatectomy-celiac axis resection group. The distal pancreatectomy-celiac axis resection group had a significantly better prognosis than the unresectable group (median survival time, 20.8 vs 9.8 months; P = .01). Aggressive resection for T4 pancreatic body cancer by distal pancreatectomy-celiac axis resection can be justified for otherwise unresectable tumors. The surgical indication should be evaluated carefully because of the higher incidence of morbidity and lower incidence of curability compared with distal pancreatectomy, as well as because there have been no long-term survivors so far.

Surgical strategy for patients with pancreatic body/tail carcinoma: who should undergo distal pancreatectomy with en-bloc celiac axis resection?

Indications for distal pancreatectomy with en-bloc celiac axis resection (DP-CAR) in pancreatic carcinoma remain controversial. Fifty-two consecutive patients with pancreatic cancer who underwent distal pancreatectomy, including 36 standard distal pancreatectomies (standard DP) and 16 DP-CAR were reviewed retrospectively. After standard DP, microscopically positive margins were identified at the dissection sites around the transection margins of the splenic arteries and were detected more frequently in the patients with tumors within 10 mm from the root of the splenic artery (14%). After DP-CAR, the estimated overall survival rate in patients who were pathologically negative for portal venous and artery invasion (n = 7) was greater than that of the other patients (n = 9; P = .023, log-rank test). The estimated overall 1- and 2-year survival rates after standard DP/DP-CAR were 81/81% and 52/53%, and the median survival times were 32/25 months, respectively, with no differences noted between the groups. There were no differences in the mortality rates and the incidence of each complication between the 2 groups except for delayed gastric emptying. DP-CAR was a feasible and safe procedure, similar to standard DP. DP-CAR should be reserved for patients without tumor infiltrating either the portal venous or arterial systems.
