Pancreatic ductal adenocarcinoma (PDAC) patients frequently present with borderline resectable disease, which can be due to invasion of the portal/superior mesenteric vein (PV/SMV). Here, we analyzed this group of patients, with emphasis on short and long-term outcomes.
156 patients who underwent a resection for PDAC were included in the analysis and sub-stratified into a cohort of patients with PV/SMV resection (n = 54) versus those with standard surgeries (n = 102).
While venous resections could be performed safely, there was a trend towards shorter median survival in the PV/SMV resection group (22.7 vs. 15.8 months, p = 0.157). These tumors were significantly larger (3.5 vs. 4.3 cm; p = 0.026) and margin-positivity was more frequent (30.4% vs. 44.4%, p = 0.046).
Venous resection was associated with a higher rate of margin positivity and a trend towards shorter survival. However, compared to non-surgical treatment, resection offers the best chance for long term survival.
胰腺导管腺癌（PDAC）患者常表现为可切除边缘的疾病，这可能是由于门静脉/肠系膜上静脉（PV/SMV）受侵所致。在此，我们分析了这组患者，重点关注短期和长期预后。
156例行PDAC切除术的患者纳入分析，并分为PV/SMV切除术组（n = 54）和标准手术组（n = 102）。
虽然静脉切除术可安全进行，但PV/SMV切除术组的中位生存期有缩短趋势（22.7个月对15.8个月，p = 0.157）。这些肿瘤明显更大（3.5 cm对4.3 cm；p = 0.026），切缘阳性更常见（30.4%对44.4%，p = 0.046）。
静脉切除术与切缘阳性率较高及生存期缩短趋势相关。然而，与非手术治疗相比，手术切除为长期生存提供了最佳机会。
