BACKGROUND/AIMS: In the treatment of adenocarcinoma of the pancreas, we have succeeded in both decreasing the locoregional recurrence and improving the patient's survival by adding a wide range of lymphatic and connective tissue clearance to the conventional pancreatectomy. The present paper shows the detailed techniques of this procedure and the factors associated with long-term survival to provide a better understanding of the indications and limitations.
The postoperative survival rate in association with the background factors of the tumor and the quality of life is analyzed in 62 patients who received an extended pancreatectomy of ductal carcinoma of the pancreas. In this procedure, a wide range of lymphatic and connective tissue clearance was cleared in addition to the pancreatectomy, skeletonizing the major vessels.
The long-term survivors had the following background factors: tumor diameter 4 cm or less; no nodal involvement or involvement limited to the immediate region of the tumor (n1-group); PV/SMV-invasion was absent or slight (2 cm or less in length and hemilateral). Long-term survival was rarely expected for any patients who had more advanced factors. Since removing the nerve plexi and connective tissues skeletonize major vessels, most patients did not recover their health easily within one post-operative year.
While our extended pancreatectomy is the most promising procedure at present, providing the candidate is appropriate, its indication should be carefully selected because of the patient's quality of life and cost-performance.
背景/目的:在胰腺癌的治疗中,我们通过在传统胰腺切除术中增加广泛的淋巴和结缔组织清扫,成功降低了局部区域复发率并提高了患者生存率。本文展示了该手术的详细技术以及与长期生存相关的因素,以便更好地理解其适应证和局限性。
分析了62例行胰腺导管癌扩大切除术患者的术后生存率与肿瘤背景因素及生活质量的关系。在此手术中,除了胰腺切除术外,还进行了广泛的淋巴和结缔组织清扫,使主要血管骨骼化。
长期生存者具有以下背景因素:肿瘤直径4cm或更小;无淋巴结转移或转移仅限于肿瘤紧邻区域(n1组);无门静脉/肠系膜上静脉侵犯或侵犯轻微(长度2cm或更小且为单侧)。对于任何具有更晚期因素的患者,很少能预期其长期生存。由于切除神经丛和结缔组织会使主要血管骨骼化,大多数患者在术后一年内不易恢复健康。
虽然我们的扩大胰腺切除术目前是最有前景的手术方法,但鉴于患者的生活质量和性价比,在选择合适的候选患者时,应谨慎选择其适应证。
