Pancreatic cancer (PC) is the fourth leading cause of cancer death worldwide, symptoms are few and diffuse, and when the diagnosis has been made only 10-15% would benefit from resection. Surgery is the only potentially curable treatment for pancreatic cancer, and the prognosis seems to improve with early detection. A hereditary component has been identified in 1-10% of the PC cases. To comply with this, screening for PC in high-risk groups with a genetic disposition for PC has been recommended in research settings.
Between January 2006 and February 2014 31 patients with Hereditary pancreatitis or with a disposition of HP and 40 first-degree relatives of patients with Familial Pancreatic Cancer (FPC) were screened for development of Pancreatic Ductal Adenocarcinoma (PDAC) with yearly endoscopic ultrasound. The cost-effectiveness of screening in comparison with no-screening was assessed by the incremental cost-utility ratio (ICER).
By screening the FPC group we identified 2 patients with PDAC who were treated by total pancreatectomy. One patient is still alive, while the other died after 7 months due to cardiac surgery complications. Stratified analysis of patients with HP and FPC provided ICERs of 47,156 US$ vs. 35,493 US$ per life-year and 58,647 US$ vs. 47,867 US$ per QALY. Including only PDAC related death changed the ICER to 31,722 US$ per life-year and 42,128 US$ per QALY. The ICER for patients with FPC was estimated at 28,834 US$ per life-year and 38,785 US$ per QALY.
With a threshold value of 50,000 US$ per QALY this screening program appears to constitute a cost-effective intervention although screening of HP patients appears to be less cost-effective than FPC patients.
胰腺癌(PC)是全球第四大致癌死亡原因,症状较少且不具特异性,确诊时仅有10 - 15%的患者可通过手术切除获益。手术是胰腺癌唯一可能治愈的治疗方法,早期发现似乎可改善预后。已在1 - 10%的胰腺癌病例中发现遗传因素。因此,在研究环境中,建议对有胰腺癌遗传倾向的高危人群进行胰腺癌筛查。
2006年1月至2014年2月期间,对31例遗传性胰腺炎患者或有遗传性胰腺炎倾向的患者以及40例家族性胰腺癌(FPC)患者的一级亲属进行筛查,每年通过内镜超声检查是否发生胰腺导管腺癌(PDAC)。通过增量成本效益比(ICER)评估筛查与不筛查相比的成本效益。
通过对FPC组进行筛查,我们发现2例PDAC患者接受了全胰切除术治疗。1例患者仍存活,另1例在7个月后因心脏手术并发症死亡。对遗传性胰腺炎患者和FPC患者的分层分析显示,每生命年的ICER分别为47,156美元和35,493美元,每质量调整生命年(QALY)的ICER分别为58,647美元和47,867美元。仅纳入与PDAC相关的死亡病例后,每生命年的ICER变为31,722美元,每QALY的ICER变为42,128美元。FPC患者的ICER估计为每生命年28,834美元,每QALY为38,785美元。
以每QALY 50,000美元的阈值来看,该筛查项目似乎是一种具有成本效益的干预措施,尽管对遗传性胰腺炎患者的筛查似乎不如对FPC患者的筛查那样具有成本效益。
