The survival impact of distal pancreatectomy (DP) with celiac axis resection for locally advanced pancreatic body/tail cancer remains unclear.
A total of 16 patients underwent DP with celiac axis resection, while 76 underwent standard DP for pancreatic body/tail cancer. The indications for DP with celiac axis resection included: (a) tumor invasion of either the celiac axis or common hepatic artery or both [CA/CHA (+)] and (b) tumor invasion of the root of the splenic artery, which is difficult to dissect without securing an adequate surgical margin [CA/CHA (-)].
DP with celiac axis resection presented longer operative time and greater amount of blood loss than DP. The median survival time was 17.5 months in the DP with celiac axis resection group and 43.1 months in the DP group (p = 0.040). Among the patients who underwent DP with celiac axis resection, the median survival time was 35.1 months in the CA/CHA (-) group and 13.2 months in the CA/CHA (+) group (p = 0.001). Comparing the patients undergoing standard DP and DP with celiac axis resection with a CA/CHA (-) status, there were no significant differences in either disease-free or overall survival times. The CA19-9 value, CA/CHA (+) status, and microscopic venous infiltration were revealed independent significant prognostic factors.
DP with celiac axis resection should therefore be indicated in patients with a CA/CHA (-) status. However, it is difficult to justify the use of DP with celiac axis resection in patients with CA/CHA (+) status due to the poor survival.
对于局部进展期胰体/尾癌行远端胰腺切除术(DP)联合腹腔干切除术的生存影响尚不清楚。
共有16例患者接受了DP联合腹腔干切除术,而76例患者接受了标准的胰体/尾癌DP手术。DP联合腹腔干切除术的指征包括:(a)肿瘤侵犯腹腔干或肝总动脉或两者[CA/CHA(+)],以及(b)肿瘤侵犯脾动脉根部,在未确保足够手术切缘的情况下难以解剖[CA/CHA(-)]。
与DP相比,DP联合腹腔干切除术的手术时间更长,失血量更多。腹腔干切除术组的中位生存时间为17.5个月,DP组为43.1个月(p = 0.040)。在接受DP联合腹腔干切除术的患者中,CA/CHA(-)组的中位生存时间为35.1个月,CA/CHA(+)组为13.2个月(p = 0.001)。比较接受标准DP和CA/CHA(-)状态的DP联合腹腔干切除术的患者,无病生存时间或总生存时间均无显著差异。CA19-9值、CA/CHA(+)状态和镜下静脉浸润是独立的显著预后因素。
因此,CA/CHA(-)状态的患者应行DP联合腹腔干切除术。然而,由于生存率低,对于CA/CHA(+)状态的患者,很难证明使用DP联合腹腔干切除术是合理的。
