Diagnostic-therapeutic management of bile duct cancer

World Journal of Clinical Cases 2019年第14期7卷 1732-1752页

作者： José María Huguet miriam Lobo José Mir Labrador Carlos Boix Cecilia Albert Luis Ferrer-Barceló Ana B Durá Patricia Suárez Isabel Iranzo Mireia gil-Raga Celia Baez de Burgos Javier Sempere Digestive Disease Department General University Hospital of ValenciaValencia 46014Spain Medical Oncology Department General University Hospital of ValenciaValencia 46014Spain Unidad Hepática Avanzada Servicio de Cirugía General y DigestivaGeneral University Hospital of ValenciaValencia 46014Spain Medical Oncology Department Hospital de RequenaRequena 46340Spain

Biliary tract cancer, or cholangiocarcinoma, comprises a heterogeneous group of malignant tumors that can emerge at any part of the biliary tree. This group is the second most common type of primary liver cancer. Diagnosis is usually based on symptoms, which may be heterogeneous, and nonspecific biomarkers in serum and biopsy specimens, as well as on imaging techniques. Endoscopy-based diagnosis is essential, since it enables biopsy specimens to be taken. In addition, it can help with locoregional staging of distal tumors. Endoscopic retrograde cholangiopancreatography is a key technique for the evaluation and treatment of malignant biliary tumors. Correct staging of cholangiocarcinoma is essential in order to be able to determine the degree of resectability and assess the results of treatment. The tumor is staged based on the TNM classification of the American Joint Committee on Cancer. The approach will depend on the classification of the tumor. Thus, some patients with early-stage disease could benefit from surgery;complete surgical resection is the cornerstone of cure. However, only a minority of patients are diagnosed in the early stages and are suitable candidates for resection. In the subset of patients diagnosed with locally advanced or metastatic disease, chemotherapy has been used to improve outcome and to delay tumor progression. The approach to biliary tract tumors should be multidisciplinary, involving experienced endoscopists, oncologists, radiologists, and surgeons.

背景社区获得性肺炎(CAP)风险在初级保健中的信息是有限的。我们评估了不同生活方式和共病条件作为初级保健成人CAP的危险因素。方法一项回顾性观察对照研究。使用国家初级保健数据监测系统检索了2009至2013年在西班牙初级保健部门诊断的成人CAP病例。匹配年龄和匹配性别的对照组采用发病率密度抽样(比例2∶1)。以百分比和比值比来表示关联分析。为了避免偏倚效应,建立二项回归模型。结果51 139例患者和102 372例对照组做比较。平均年龄为61.4(19.9)岁。危险因素与CAP的显著相关性如下:艾滋病[比值比(95%可信区间)5.21(4.35~6.27)]、慢性阻塞性肺病(COPD)[2.97(2.84~3.12)]、哮喘[2.16(2.07~2.26)]、吸烟[1.96(1.91~2.02)]和口腔卫生问题[1.45(1.41~1.49)]。患者组中有危险因素存在的平均患病率为82.2%,对照组为69.2%。CAP患病率的增加与危险因素和年龄的累积有关:1个危险因素时,在18~60岁老人中的风险相关性是1.42,在>60岁人中是1.57;2个危险因素时,是1.88和2.35;≥3个危险因素时,是3.11和4.34。结论成人CAP初级保健中的危险因素普遍较高。主要与危险因素相关的是艾滋病、COPD、哮喘、吸烟、口腔卫生问题。我们的风险叠加结果可以帮助临床医生确定肺炎风险较高的患者。
