Pancreatic carcinoma is a type of cancer with an extremely poor prognosis. Surgery is the only curative option, and only possible in a minority of patients. After surgery the 5-year survival rate is approximately 25%. The role of radiochemotherapy in the treatment of locally advanced pancreatic cancer and in the adjuvant setting is discussed:--Locally advanced disease: Numerous studies are being performed to improve disease free survival in locally advanced disease. So far the combination of high dose radiotherapy and continuous infusion of 5-fluorouracil appears to be the best option. However, the potential gain is limited, and this should be weighed against the burden of treatment for patients with a very short life expectancy. New combinations are being investigated.--Adjuvant treatment: After radical surgery there is no standard adjuvant treatment. Four randomized trials were performed so far. In one of these only the role of chemotherapy was investigated. In the three other trials the radiochemotherapy applied was not optimal. Yet a trend for a survival benefit was seen in two of these trials, at least in the subgroup of pancreatic head cancer. One of the four trials appears to show a benefit from chemotherapy. These results warrant further investigation of the role of (optimal) radiochemotherapy, and the role of chemotherapy. In collaboration with the FFCD and GERCOR, the EORTC will start an international multicenter randomized phase III study comparing high dose radiotherapy and concomitant continuous infusion of 5-FU versus control after pancreatico-duodenectomy for pancreatic head cancer (22995/40992).
胰腺癌是一种预后极差的癌症。手术是唯一的治愈选择,但仅适用于少数患者。术后5年生存率约为25%。本文讨论了放化疗在局部晚期胰腺癌治疗及辅助治疗中的作用:——局部晚期疾病:目前正在进行大量研究以提高局部晚期疾病的无病生存率。到目前为止,高剂量放疗联合持续输注5-氟尿嘧啶似乎是最佳选择。然而,潜在获益有限,应权衡其对预期寿命很短的患者的治疗负担。新的联合方案正在研究中。——辅助治疗:根治性手术后尚无标准的辅助治疗方案。目前进行了四项随机试验。其中一项仅研究了化疗的作用。在其他三项试验中,应用的放化疗并不理想。然而,在其中两项试验中至少在胰头癌亚组中观察到了生存获益的趋势。四项试验中的一项似乎显示化疗有获益。这些结果值得进一步研究(最佳)放化疗的作用以及化疗的作用。欧洲癌症研究与治疗组织(EORTC)将与法国消化道肿瘤协作组(FFCD)和胃肠肿瘤研究组(GERCOR)合作,开展一项国际多中心随机III期研究,比较胰十二指肠切除术后高剂量放疗联合持续输注5-氟尿嘧啶与对照组治疗胰头癌的疗效(22995/40992)。
