Does portal-superior mesenteric vein invasion still indicate irresectability for pancreatic carcinoma?
GROUND: Pancreatic carcinoma frequently infiltrates the portal vein or the superior mesenteric vein; pancreatectomy combined with portal vein/superior mesenteric vein resection represents a potentially curative treatment in these cases but is still a controversial procedure. METHODS: After performing a computerized Medline search, 12 series published during the last 8 years were selected, enrolling 399 patients who underwent pancreatectomy combined with portal vein/superior mesenteric vein resection for pancreatic carcinoma. Data were examined for information about indications, operation, adjuvant therapies, histopathology of resected specimens, perioperative results, and survival. Also, previous literature regarding the issue was extensively reviewed. RESULTS: Operative mortality and postoperative complication rates ranged from 0 to 7.7% and 16.7% to 54%, respectively. Median survival varied from 13 to 22 months; 5-year survival rate ranged from 9% to 18%. CONCLUSIONS: The current lit
