摘要目的 探讨胰腺癌疼痛的发病率及其临床特征.方法 回顾性分析广州医学院附属广州市第一人民医院和中山大学附属第二医院1999年至2007年收治的415例胰腺癌病例资料,探讨癌痛发生率、临床特征及其与肿瘤部位、临床分期的关系.结果 胰腺癌疼痛发生率为65.1%(270/415),60.5%(251/415)的患者以疼痛为首发症状,Ⅰ级疼痛占42.2%(114/270),Ⅱ级疼痛44.1%(119/270),Ⅲ级疼痛13.7%(37/270).以上腹部疼痛多见,多表现为持续性或阵发性隐痛、胀痛.胰体尾癌患者的疼痛发生率为80.7%,全胰癌患者为71.4%,胰头癌患者为58.2%,胰体尾癌与胰头癌患者的疼痛发生率相差显著(P＜0.05));Ⅰ期、Ⅱ期、Ⅲ期和Ⅳ期胰腺癌患者的疼痛发生率分别为28.6%、58.1%、66.2%和78.6%,相差非常显著(P＜0.01);中、重度疼痛在Ⅰ、Ⅱ、Ⅲ、Ⅳ期患者中所占比例分别为18.8%、44.4%、53.1%和68.2%,相差也非常显著(P＜0.01).结论 进展期胰腺癌的癌痛非常常见,发生率及严重程度随肿瘤进展而加重.

abstractsObjective To investigate the prevalence and the clinical features of pancreatic cancer pain in a Chinese patient population.Methods The study was carried out in 415 cages of pancreatic cancer which were admitted to the First Municipal people's Hospital of Guangzhou Medical college and the Second Affiliated Hospital of Sun Yat-sen University from 1999 to 2007.The prevalence,clinical features of pancreatic cancer pain and its correlations with the cancer site and the clinical staging were analyzed.Results Of the 415 patients.the prevalence of pain wag 65.1%and 60.5%of all the patients presented pain as the initial symptom;the incidence of pain in pancreatic body/tail cancer patients was 80.7%.while it was 71.4%in total pancreatic cancer patients.and the incidence was 58.2%in pancreatic head cancer patients;the incidence between pancreatic body/tail cancer and pancreatic head cancer patients was statistically different (P＜0.05).The incidence of pain in patients with stage Ⅰ,Ⅱ,Ⅲ,and Ⅳ was 28.6%,58.1%,66.2%and 78.6%.and the difference was statistically significant(P＜0.01).The incidence of moderate to severe degree of pain in patients with stage Ⅰ,Ⅱ,Ⅲ,and Ⅳ was 18.8%,44.4%,53.1%and 68.2%,and the differenee was statistically significant(P＜0.01).Conclusions Pain was very common in patients with advanced pancreatic cancer.The incidence and severity of pain increased with the progression of pancreatic cancer.
