Pancreatic ductal adenocarcinoma has a very high mortality rate which has been only minimally improved in the last 30 years. This high mortality is closely related to late diagnosis, which is usually made when the tumor is large and has extensively infiltrated neighboring tissues or distant metastases are already present. This is a paradoxical situation for a tumor that requires nearly 15 years to develop since the first founding mutation. Response to chemotherapy under such late circumstances is poor, resistance is frequent, and prolongation of survival is almost negligible. Early surgery has been, and still is, the only approach with a slightly better outcome. Unfortunately, the relapse percentage after surgery is still very high. In fact, early surgery clearly requires early diagnosis. Despite all the advances in diagnostic methods, the available tools for improving these results are scarce. Serum tumor markers permit a late diagnosis, but their contribution to an improved therapeutic result is very limited. On the other hand, effective screening methods for high-risk populations have not been fully developed as yet. This paper discusses the difficulties of early diagnosis, evaluates whether the available diagnostic tools are adequate, and proposes some simple and not-so-simple measures to improve it.
胰腺导管腺癌的死亡率极高,在过去30年里仅有微小改善。这种高死亡率与诊断延迟密切相关,诊断通常在肿瘤体积较大、已广泛浸润邻近组织或已有远处转移时才做出。对于一个从首次发生奠基性突变起需要近15年才发展形成的肿瘤来说,这是一种自相矛盾的情况。在这种晚期情况下,化疗反应不佳,耐药常见,生存期延长几乎可以忽略不计。早期手术一直以来都是,并且现在仍然是唯一一种结果稍好的治疗方法。不幸的是,术后复发率仍然非常高。事实上,早期手术显然需要早期诊断。尽管诊断方法取得了诸多进展,但用于改善这些结果的可用工具却很匮乏。血清肿瘤标志物只能实现晚期诊断,但其对改善治疗结果的作用非常有限。另一方面,针对高危人群的有效筛查方法尚未完全开发出来。本文讨论早期诊断的困难,评估现有诊断工具是否足够,并提出一些简单和不太简单的措施来改善早期诊断。
