奥曲肽治疗化疗相关性腹泻最终版

1、Octreotide in chemotherapy induced diarrhoea in colorectal cancer: a review article奥曲肽治疗直肠癌患者化疗相关性诱发腹泻：综述Abstract 摘要Background: Chemotherapy-induced diarrhea(CID)is well known in cancer management.

2、of octreotide in CID through an extensive literature search.背景：化疗相关性诱发腹泻(CID)在癌症治疗中比较常见。特别是原发灶位于直肠 的癌症则风险更大。本文旨在通过全面的文献检索评价奥曲肽治疗CID的作用。Methods： After searching through PUBMED,MEDLINEd the Cochrane library, only those studies which were published over the last 20 years in English and where at least t

3、he majority of the cohort were colorectal patients, were included. Tworandomized trials, four non-randomized studies and two case-series publications were thus considered.方法：检索PUBMED,MEDL和循证医学图书馆，选出最近 20年用英文发表的、 并且至少所选的主要观察队列为结肠病人的研究论文。符合条件的共有两项随机 对照试验，四项非随机研究和两篇系列案例研究文献。Results: It was seen in both

4、 the randomized studies, that octreotide had much better outcome as compared to loperamide in treating severe CID.Among 88 patients from the non-randomized studies with severe CID, the primary cancer was colorectal in 79 patients.61 patients had drug-resistant CID. Within a maximumof 96 hours, octre

5、otide reduced CID by 2 grades in 91% of 88 patients and in 88.52% patients with drug-resistant CID.结果：随机对照试验研究结果显示，奥曲肽治疗严重CID的疗效比咯哌丁胺好很 多。非随机研究结果显示，88例严重CID病人中，原发是结肠癌的有79例。其 中61例病人有CID抗药性。用奥曲肽治疗最长时间为96个小时后，88例严重 CID病人中，抗药性降低的患者为91%抗药性患者中88.52%患者的CID评分至少2级。Conclusion: Octreotide is effecti ve in trea

6、ting severe CID, resistant to other modes of treatment. It is associated with a few minor adverse effects. Though expensive, octreotide could be considered as first line medication in CID of grades 3 or above. Its use in lower grades of CID would not be cost effective.结论：奥曲肽对其他治疗方式无效的严重CID患者有效，且不良反应

7、较少。 尽管价格比较昂贵，奥曲肽仍可考虑作为 CID评分3级以上患者的一线药物。在低级别的CID治疗中，奥曲肽的作用并不是很大。Key words: octreotide, chemotherapy induced diarrhoea, octreotide in diarrhoea.关键词：奥曲肽，化疗导致的腹泻，奥曲肽治疗腹泻Abbreviations 缩写CID = Chemotherapy induced diarrhoea 化疗相关性 诱发腹泻5FU = 5 Fluorouracil5-氟尿 口密咤UFT=Uracil 优福定NCI=National Cancer Institute

Chemotherapy regimens used in adjuvant(4,5) and metastatic(6,7) colorectal disease and respective incidences of CID are summarized in the charts(Fig.2.3).所有的杜克斯C期，高危的杜克斯B期和转移的结直肠癌似乎都可考虑手术后化疗(DukesB/C期)或姑息性化疗(

Diarrhoea can cause dehydration, electrolyte imbalance, renal impairment ,nutritional deficiency and can have negative impact on the management of cancer itself. Severe diarrhea decreases patient

Diarrhoea can be associated with chemotherapy induced neutropenia, which can be serious or even fatal. The s

17、everity of the CID is assessed by the National Cancer Institute(NCI) criteria(16).Dranitsaris and colleagues reported an incidence of 54.2% diarrhoea after the first cycle of chemotherapy in a retrospective study and this resulted in a median dose reduction by 20% and median delay in treatment by 7

18、days. 32.3% cases in this study neededhospitalization and their median length of hospital stay was 8 days （21）.卡培他滨，伊立替康，西妥昔单抗和5-氟尿喀咤推注方案通常导致高腹泻率（8-12）。原发性结直肠癌是CID的独立的危险因素。文献报道的其他的独立的危险因素有化疗早期疗程导致的腹泻、夏季化疗相关性 诱发腹泻以及老年组女性（14,15）、双氢喀咤脱氢酶（DPD）缺乏，尿甘二磷酸葡萄糖醛酸基转移酶缺乏（UGT） （16-20）以及与姑息性治疗相比较的辅助化疗（16）。腹泻会导致脱水、

19、电解质失衡、肾损害、营养缺乏，并且对癌症治疗本身有负面影响。严重的腹泻降低患者对于化疗的耐受能力，从而导致剂量的减少和治疗结束过早。发病率增加提高了治疗成本，并且导致不良的治疗结果。腹泻可能与化疗诱发的嗜中性白血球减少症有关，可能非常严重甚至致命。NCI划分了 CID的严重性等级。Dranitsaris及其同事在一项回溯性研究中报道， 第一个疗程后腹泻发生率为54.2%,这导致治疗剂量平均降低 20%, 治疗时间平均延长 7天。此项研究中32.3%的患者需要住院治疗，并且平均住院期为8天。Fig.1.-NCI grading of diarrheaNational Cancer Institu

When we combined the results of all these non-randomized studies, in a cohort of 88 patients (colorectal cancer in 79 out of 88 cases) with severe CID (NCI grades 3 and above), 61 patients (69.32%) with opioids or loperamide resistant CID were treated with octreotide, which wa

In this cohort, nearly 16% of patients had complete resolution of diarrhea and about 29

41、% experienced reduction of diarrhea by at least two grades.

47、的CID患者( 69.32%)使用奥曲肽治疗，54名患者( 88.52%)在4 天内腹泻得到有效控制。Two case series publications by Rosenoff (28,29) reported successful treatment of severe CID (NCI grades 3 and above), refractory to loperamide and/or diphenoxylate atropine, by octreotide LAR(long acting release preparation). Both these publication

48、s demonstrated improvement in patient s quality of life and tolerance towards chemotherapy. No serious adverse effects were reported in either of them.Rosenoff (28,29)发表的两个病例系列报道了使用长效奥曲肽治愈对洛哌丁胺和/或地芬诺脂阿托品有抗药性的严重的CID （NCI级别3以上）患者。这两篇论文都表明，奥提高了对化疗的耐受能力， 均未报道严重的不良反应。Dose of octreotide in CID治疗CID时奥曲肽的剂量

49、In the absence of fixed dose related guidelines, the use of octreotide in CID has been purely empirical. The Canadian Working Group on CID has recommended that patients with grade 2 CID (NCI grading) refractory to loperamide or opioids and grade 3 or 4 CID should have octreotide at a dose of 100-150

50、 micrograms subcutaneously thrice daily. In refractory diarrhea, doses may be increased up to 500 micrograms thrice daily (16,30).由于没有固定剂量的相关指导，奥曲肽治疗CID完全凭经验。加拿大 CID工作小组对抗洛哌丁胺或鸦片的CID2级患者(NCI分级)和3或4级CID患者的推荐剂量是皮下注射奥曲肽 100-150 微克，一天三次。对顽固性腹泻患者，剂量可以增加到 500 微克，一天 三次( 16,30 ) 。The Canadian working group

51、also recommends that octreotide LAR 30 mg (intramuscularly, once every 28 days) can be used prophylactically in any patient with colorectal cancer receiving chemotherapy who had experienced CID with the previous cycles(16).该小组还推荐使用长效奥曲肽30mg (肌肉注射，每28 天一次)对任何接受化疗的在以前的疗程中有CID病史的结直肠癌患者进行预防性的治疗(16)。Dose

52、 efficacy of octreotide LAR ( Long acting 40 mg VS 30mg) has been assessed by Rosenoff and colleagues in a multicentre, randomized, open-label study (31). The mean duration of anti-diarrhoeal treatment was found to be shorter for octreotide. Statistical significance was reached with both these resul

53、ts (p 0.001). In this trial, although fewer patients in the 40 mg group experienced severe (grades 3-4) diarrhea and unscheduled healthcare support as compared to the 30 mg group, none of these differences were statistically significant.Rosenoff 及其同事在一项多中心随机标签公开的研究中已对长效奥曲肽(长效40mg 对比30mg)的剂量效果进行了评价(3

54、1),发现奥曲肽组治疗腹泻所需的平均时间周期更 短。两项结果都具有显著的统计学意义 (pv 0.001)。在该项试验中，尽管相对于30mg组， 40mg 组患有严重腹泻(3 4 级)症状和得到额外健康护理支持的患者均少，这些差别没有显著的统计学意义。But this trial introduced the possibility of secondary prevention of CID by octreotide.Octreotide has a positive dose- response effect in CID, as shown by Goumas et al. in a r

55、andomized study, where patients with severe, loperamide resistant, CID were treated by thrice daily doses of either 100ug or 500ug of (subcutaneous) octreotide. Complete resolution was reported in 90.32% patients in the 500-microgram arm as compared to 60.71% in the 100-microgram arm (p0.05) (30). I

56、n a phase I trial performed to demonstrate the safe dose of octreotide in fluoropyrimidine-induced diarrhea in 35 patients, the maximum tolerated dose was found to be 2000 micrograms (subcutaneous) thrice daily (32).但是这个试验提出了奥曲肽对于CID二级预防的可能性。正如 Goumas等指出，奥曲肽对CID患者具有正性的剂量响应效果。在一项随机研究中，每天三次100ug或500ug

57、奥曲肽(皮下注射)治疗严重的、对洛哌丁胺抗药患者的CID。结果显示，500mg剂量组患者的治愈率为 90.32%, 100mg患者组的治愈率为60.71%(pv0.05) (30)。在35名患者参加的 I 期临床试验中证明奥曲肽治疗氟嘧啶诱导的腹泻的安全剂量，发现最大耐量是 每天三次 2000mg (皮下注射) ( 32) 。Adverse effects related to the use of octreotide in CID 治疗 CID时奥曲肽的副作用An extensive literature search has revealed that octreotide is saf

58、e, well-tolerated drug and effective with minimal adverse effects within the therapeutic range when used in CID (26,32)(Fig.5). Local pain at the injection site was reported by Gebbia et al.(23) and Barbounis et al.(24)(incidences of 15% and 38%) in their respective studies. But none of these were s

59、evere enough for cessation of therapy. Local pain was short lived and no longer than 15 minutes. This can be avoided if the vial is warmed prior to drug administration(33).大量的文献检索结果显示，奥曲肽是安全和耐受良好的药物，在有效浓度范围内治疗CID有效而且副作用极少 (26,32)(图5.)。Gebbia等(23)和Barbounis等(24)在其各自的 研究中提到了注射部位的局部疼痛(发生率分别为15%和 38%) 。

60、但这些副作用都未严重到中止治疗。局部疼痛的时间短暂，不超过15 分钟。而且在注射之前将安瓶加热即可以避免(33 ) 。Symptoms like increased diarrhea or looseness of stools, vitamin B12 deficiency andpotential risk of gallstone formation (12-60%) are associated with long-term octreotide use in CID, because of the short duration of therapy in the latter.长期使
