About a third of all pancreatic cancer is found to be locally advanced at the time of diagnosis, where the tumor is inoperable but remains localized to the pancreas and regional lymphatics. Sadly, this remains a universally deadly disease with progression to distant disease being the predominant mode of failure and average survival under one year. Optimal treatment of these patients continues to be an area of controversy, with chemotherapy alone being the treatment preference in Europe, and chemotherapy followed by chemoradiation in selected patients, preferred in the USA. The aim of this paper is to summarize the key abstracts presented at the 2013 ASCO Annual Meeting that address evolving approaches to the management of locally advanced pancreatic cancer. The late breaking abstract (#LBA4003) provided additional European data showing non-superiority of chemoradiation compared to chemotherapy in locally advanced pancreatic cancer patients without distant progression following 4 months of chemotherapy. Another late breaking abstract, (#LBA4004), unfortunately showed a promising new complement to gemcitabine and capecitabine using immunotherapy in the form of a T-helper vaccine did not translate to improved survival in the phase III setting.
约三分之一的胰腺癌在确诊时被发现为局部进展期,此时肿瘤无法手术切除,但仍局限于胰腺及区域淋巴结。遗憾的是,这仍是一种普遍致命的疾病,远处转移是主要的失败模式,平均生存期不到一年。这些患者的最佳治疗方案仍是一个有争议的领域,在欧洲,单纯化疗是首选治疗方法,而在美国,部分患者首选化疗后进行放化疗。本文旨在总结在2013年美国临床肿瘤学会(ASCO)年会上发表的关键摘要,这些摘要涉及局部进展期胰腺癌管理的不断演变的方法。最新摘要(#LBA4003)提供了更多欧洲数据,表明在接受4个月化疗后无远处进展的局部进展期胰腺癌患者中,放化疗并不优于化疗。另一个最新摘要(#LBA4004)不幸表明,以T辅助疫苗形式使用免疫疗法作为吉西他滨和卡培他滨的一种有前景的新补充,在III期试验中并未转化为生存期的改善。
