The standard treatment of resectable pancreatic cancer is surgery followed by adjuvant chemotherapy. Due to the complication rate of pancreatic surgery and the high rate of primary irresectability, neoadjuvant concepts are increasingly used for pancreatic cancer. Neoadjuvant therapy is better tolerated than adjuvant and might decrease the surgical complication rate from pancreatic surgery. In contrast to neoadjuvant chemoradiation, the nutritional status improves during neoadjuvant chemotherapy. Also, the survival of patients who develop postoperative complications after neoadjuvant therapy is comparable to those without complications whereas the survival of patients who underwent upfront surgery and then develop surgical complications is impaired. Moreover, large data base analyses suggest a down-sizing effect and improvement of overall survival by neoadjuvant therapy. Neoadjuvant chemotherapy appears to be equally efficient in converting irresectable in resectable disease and more efficient with regard to systemic tumor progression and overall survival compared to neoadjuvant chemoradiation therapy. Despite these convincing findings from mostly small phase II trials, neoadjuvant therapy has not yet proven superiority over upfront surgery in randomized trials.
可切除胰腺癌的标准治疗方法是手术加辅助化疗。由于胰腺手术的并发症发生率高和原发性不可切除率高,新辅助治疗的概念越来越多地用于胰腺癌。新辅助治疗比辅助治疗更耐受,可能降低胰腺手术的并发症发生率。与新辅助放化疗相比,新辅助化疗期间营养状况得到改善。此外,接受新辅助治疗后发生术后并发症的患者的生存率与无并发症患者相当,而接受直接手术然后发生手术并发症的患者的生存率则受到影响。此外,大型数据库分析表明,新辅助治疗具有缩小肿瘤和改善总体生存的效果。与新辅助放化疗相比,新辅助化疗在将不可切除的肿瘤转化为可切除肿瘤方面同样有效,并且在控制系统性肿瘤进展和总体生存方面更有效。尽管这些来自大多是小的 II 期临床试验的令人信服的结果表明,新辅助治疗在随机试验中尚未证明优于直接手术。
