Cholangiocarcinoma (CCA) is an uncommon malignant tumor arising from the biliary epithelium. The incidence increases with age and usually affects individuals in their 6th or 7th decade of life. Those patients with underlying risk factors such as primary sclerosing cholangitis (PSC) and choledochal cysts generally present 2 decades earlier. Most patients clinically present with painless jaundice; however, other common symptoms include pruritus, weight loss, and abdominal pain. Although surgical resection offers the only hope for cure, most patients are found to have unresectable disease on initial presentation and have an extremely grim prognosis. This has led to an emphasis on the role of palliative care, with relief of biliary obstruction, in the management of these patients. Surgical bypass was once the primary means of palliation of jaundice in patients with unresectable cholangiocarcinoma but in the last 2 decades has been superseded by less invasive and less morbid nonsurgical procedures such as endoscopic and percutaneous biliary stent placement. Newer modalities of palliation such as endoscopic delivery of photodynamic therapy and high-intensity ultrasound therapy are emerging nonsurgical modalities that may result in improved survival and may play a future role as an adjunctive therapy to surgical resection.
胆管癌(CCA)是一种起源于胆管上皮的罕见恶性肿瘤。其发病率随年龄增长而升高,通常影响60或70岁的人群。那些有原发性硬化性胆管炎(PSC)和胆总管囊肿等潜在危险因素的患者一般发病时间要早20年。大多数患者临床上表现为无痛性黄疸;然而,其他常见症状包括瘙痒、体重减轻和腹痛。尽管手术切除是唯一的治愈希望,但大多数患者在初次就诊时就被发现患有无法切除的疾病,预后极差。这使得在这些患者的管理中,姑息治疗的作用得到了重视,重点在于缓解胆道梗阻。手术旁路曾是无法切除的胆管癌患者黄疸姑息治疗的主要手段,但在过去20年中已被侵入性较小、并发症较少的非手术方法所取代,如内镜和经皮胆道支架置入术。新型姑息治疗方式,如内镜下光动力疗法和高强度超声治疗,正在成为非手术治疗方式,可能会提高生存率,并可能在未来作为手术切除的辅助治疗发挥作用。
