Pancreatic cancer is the second commonest gastrointestinal cancer, after colorectal cancer, in Canada, and most other European and North American countries. Unfortunately, most patients present with advanced locoregional or metastatic disease. For the 10-20% of patients who have localized disease, pancreatic resection is generally the preferred treatment option. Because pancreaticoduodenectomy can be performed safely in expert hands, it has become a more accepted procedure for patients with pancreatic cancer. Furthermore, it has also meant that there is increasing scrutiny of the longterm outcome of patients, especially their nutritional status and quality of life. In a study of 25 unselected patients who had a Whipple procedure at least 6 months previously and were not known to have residual or recurrent disease, patients appeared to have few gastrointestinal symptoms compared to control patients. However, none of the subjects appeared to be clinically malnourished. Dietary intake and lean body mass were comparable to that of the control group. Quality of life was excellent in these patients. The mean utilities were 0.98 and 1.0 suggesting near normal wellbeing. Similarly, results using the SIP and GIQLI suggested no/minimal impairment in general wellbeing and gastrointestinal function. Two other studies suggest that median survival and performance status are improved in patients having a resection, but it may be due to their disease being more favorable rather than the treatment being beneficial. Further studies objectively assessing the quality of life of all patients undergoing treatment for pancreatic cancer at the various disease stages are required.
在加拿大以及大多数其他欧洲和北美国家,胰腺癌是仅次于结直肠癌的第二常见胃肠道癌症。不幸的是,大多数患者就诊时已处于局部晚期或转移性疾病阶段。对于10%至20%患有局限性疾病的患者,胰腺切除术通常是首选的治疗方案。由于在经验丰富的医生手中,胰十二指肠切除术可以安全地进行,它已成为更被胰腺癌患者接受的手术。此外,这也意味着对患者的长期预后,尤其是他们的营养状况和生活质量的审查越来越严格。在一项对25例至少在6个月前接受了惠普尔手术且无残余或复发性疾病的未筛选患者的研究中,与对照组患者相比,这些患者似乎几乎没有胃肠道症状。然而,这些受试者中没有一人在临床上表现出营养不良。饮食摄入量和瘦体重与对照组相当。这些患者的生活质量极佳。平均效用值分别为0.98和1.0,表明健康状况接近正常。同样,使用SIP和GIQLI的结果表明总体健康和胃肠功能无/仅有轻微损害。另外两项研究表明,接受切除术的患者中位生存期和体能状态有所改善,但这可能是因为他们的病情更有利,而非治疗有益。需要进一步开展研究,客观评估处于不同疾病阶段接受胰腺癌治疗的所有患者的生活质量。
