MEN2主要临床表现为甲状腺髓样癌(发生率99%)、嗜铬细胞瘤(发生率50%)和甲状旁腺功能亢进等病症[2-4]。
因MEN2临床表现多样,病症复杂,常以一种自动选择的方式进行遗传,这就意味着一个家庭可能会受到相同综合征的影响。
以往的研究表明MEN2为10号染色体上RET原癌基因突变所导致。
目前研究认为,基因型与甲状腺髓样癌发生时间和恶性程度相关,临床可根据基因型制定手术时间及计划。
MEN2发病的主要原因是不同基因突变型引起了RET基本活性的转变,进而导致细胞内外信号通路的变化[1]。
尽管医学在MEN2的诊断及治疗上取得如此大的进步[3],但不可否认的是MEN2对患者产生生理、心理、社会方面的困扰,以及心理健康的负面影响。

在遗传性和散发性的甲状腺髓样癌(medullary thyroid carcinoma, MTC )中发现RET 点突变基因。
与PTC 中RET 的变化存在不同,MTC 中RET 的活化主要通过激活点突变。
RET 不同类型的重排活化与甲状腺癌的高发密切相关,RET 不同的活化机制需对应不同的治疗对策。
讨论了RET 原癌基因在甲状腺乳头状癌和甲状腺髓样癌中的致病、诊断和预后的作用,以期为RET 活化引起的甲状腺癌的治疗提供理论依据。

Activating point mutations in the RET proto -oncogene were discovered in both hereditary and sporadic forms of medullary thyroid carcinoma (MTC ). Different from the change of RET in PTC , the activation of RET in MTC is mainly through the activation point mutation. Thus , the different types of rearrangement activation of RET are closely related to the high incidence of thyroid cancer. Different activation mechanisms of RET will lead to different treatment strategies. In this review , we discussed the role of RET proto -oncogenes in the pathogenesis , diagnosis and prognosis of PTC and MTC , which was expected to provide reference for the thyroid carcinoma caused by RET activation.Key words :rearranged during transfection ; medullary thyroid carcinoma ; papillary thyroid carcinoma ; pathogenesis ; diagnosis ;prognosis甲状腺癌(thyroid carcinoma )是一种常见的内分泌腺恶性肿瘤,来源于甲状腺上皮细胞的恶性病变。
中南大学学报(医学版)J Cent South Univ (Med Sci)2020,45(10)RET 基因p.M 918T 突变导致多发性内分泌肿瘤-IIb 型1例金萍,胡文沐,杨幼波,龙晓丹,莫朝晖(中南大学湘雅三医院内分泌科,长沙410013)[摘要]多发性内分泌肿瘤-IIb 型(multiple endocrine neoplasia type-IIb ,MEN-IIb)是一种罕见的由RET 基因突变引起的常染色体显性遗传病,具有特殊的临床表型,如黏膜神经瘤、类马方综合征体型、甲状腺髓样癌及嗜铬细胞瘤等。
临床医生对此病认识不足,诊断往往延迟。
2018年11月中南大学湘雅三医院收治了1例MEN-IIb 患者,该患者自幼有舌黏膜神经瘤,曾因二尖瓣脱垂及脊柱畸形接受手术治疗,于22岁时被诊断为甲状腺髓样癌并接受手术治疗,但直至28岁发现嗜铬细胞瘤才临床诊断为MEN-IIb 。
基因检测提示该患者携带一新发RET 基因p.M918T 杂合突变。
在临床工作中早期识别内分泌系统以外的临床表现并进行RET 基因筛查是早期诊断及治疗的关键。

RET基因变异肿瘤的靶向治疗现状作者:丁思洁王融王玮来源:《中外医学研究》2020年第25期【摘要】 RET作为主要的癌症驱动基因,其变异可见于多个癌种。
随着近期肿瘤靶向治疗在EGFR突变肺癌、ALK融合肺癌中的突破性进展,靶向RET正在成为新的研究热点。
目前靶向RET的小分子抑制剂主要分为非特异性多靶点抑制剂及特异性RET抑制剂。
非特异性多靶点抑制剂已在临床前及临床研究中展现了抗RET变异肿瘤的作用。
新型选择性RET抑制剂,如BLU-667和LOXO-292等,更以其高选择性和较低的靶外毒性,为RET变异癌症患者创造了新的希望。
本文旨在结合最新研究成果,对靶向RET基因变异肿瘤的小分子抑制剂进行综述,希望能引起人们对这一领域持续研究的关注。

With the breakthrough of targeted therapy in EGFR mutant or ALK fusion lung cancer, targeted therapies of RET is becoming a hotspot recently, including several multi-kinase inhibitors ad selective RET inhibitors. Multi-kinase inhibitors have shown the effect of anti-RET rearrangement tumors in preclinical and clinical studies, while promising prospect was shown recently in selective RET inhibitors with their excellent efficacy and lower off-target toxicity. This paper reviews the research progress of targeted therapies against RET arrangement cancer from preclinical and clinical studies and proposed several considerations for clinical practice prospectively.[Key words] RET Rearrangement Cancer Targeted therapyFirst-author’s address: Nanfang Hospital, Southern Medical University, Guangzhou 510000, ChinaRET(rearranged during transfection)作為一种原癌基因,近两年因特异性小分子抑制剂的成功研发,而备受国内外关注。
中国家族遗传性肿瘤临床诊疗专家共识(2021年版)—家族遗传性甲状腺癌一、遗传性甲状腺髓样癌甲状腺髓样癌(medullary thyroid carcinoma,MTC)是来源于甲状腺滤泡旁细胞(C 细胞)的恶性肿瘤,约占甲状腺恶性肿瘤的5%,甲状腺滤泡旁细胞具有合成分泌降钙素(calcitonin,Ctn)及降钙素基因相关肽的作用。
因此,MTC 亦被认为是神经内分泌肿瘤之一。
在MTC 中25%~30% 为HMTC。
根据ATA 指南(The American Thyroid Association),HMTC 可以分为多发性内分泌肿瘤2A 型(MEN2A)和多发性内分泌肿瘤2B 型(MEN2B)。
MEN2A 型HMTC 根据临床表现的差异可分为4 种类型:经典型MEN2A、MEN2A 伴皮肤苔藓淀粉样变(cutaneous lichen amyloidosis,CLA )、MEN2A 伴先天性巨结肠(Hirschsprung's disease,HD)、家族性MTC(FMTC)。
MEN2B 型以MTC 并发黏膜多发性神经瘤为特点,通常在婴儿期发病,且具有较高的侵袭性,早期即可发生淋巴结甚至远处转移。
二、家族性甲状腺非髓样癌甲状腺非髓样癌(non-medullary thyroid carcinoma,NMTC)包括甲状腺乳头状癌(papillary thyroid carcinoma,PTC)、甲状腺滤泡癌(follicular thyroid carcinoma,FTC)和甲状腺未分化癌(anaplastic thyroid carcinoma,ATC)等起源于甲状腺滤泡上皮细胞的恶性肿瘤,约占所有TC 的90%,其中PTC 是最常见的病理类型。
5%~10% 的NMTC 患者表现为家族聚集性。
FNMTC 的定义是家族一级亲属间具有2 个或2 个以上的NMTC 患者并排除头颈部射线暴露史。

目的探讨多发性内分泌肿瘤( MEN)的临床诊治特点及RET原癌基因检测的临床意义。
方法家系中诊断MEN患者3例,男1例,50岁;女2例,38岁和33岁。
2例行双侧肾上腺全切术:1例行保留双侧肾上腺的肾上腺嗜铬细胞瘤切除术。
3例均行甲状腺全切+颈部淋巴结清扫术。
家系中12名成员抽血,提取基因组DNA,对RET原癌基因第10、11外显子行PCR检测,对PCR产物进行基因测序。
结果3例患者病理诊断为双肾上腺嗜铬细胞瘤+甲状腺髓样癌。
38岁、33岁女患者及男患者术后分别随访5年、4年2个月、1年6个月,均无肿瘤复发或转移。
3例均检测到RET原癌基因第11外显子TGC→CGC( Cys634 Arg)错义突变,使编码氨基酸由半胱氨酸变成精氨酸。
家系其他成员中发现2名该突变基因携带者。
结论对MEN高危家族的RET原癌基因检测筛选及早期手术干预是治愈MEN的关键。

RET proto-oncogene mutation analysis in a pedigree with multiple endocrine neoplasia 2A ZHANG Jin*YU Xin-juanWENG Bo-wenZHU Xin-hong* Department of Urology, Qingdao Municipal Hospital,Qingdao 266071, China
Objective To discuss the clinical diagnosis and treatment of multiple endocrine neoplasia ( MEN ) 2A, and report the mutation of the RET proto-oncogene in a pedigree of three patients with MEN 2A. Methods Bilateral adrenalectomy was performed on two of the three patients with hypertension and bilateral adrenal-conserving adrenal pheochromocytoma resection was performed on the other patient. All three patients were treated by total thyroidectomy and neck lymphadenectomy. Twelve family members were recruited to the study. Peripheral blood was collected and total genomic DNA was prepared for polymerase chain reaction (PCR). PCR products of exon 10 and exon 11 of the RET proto-oncogene were purified and a direct DNA sequence analysis was performed. Results The pathological diagnosis of the specimens was bilateral adrenal pheochromocytoma and medullary thyroid carcinoma in all the three patients. There was no tumor recurrence or distant metastasis after 1.5 - 5 years of follow-up. A missense mutation of TGC (Cys)to CGC (Arg) at codon 634 in exon 11 of the RET proto-oncogene was detected in all three patients. Genetic screening identified two mutation carriers in the other members of this pedigree. Conclusion Genetic mutation screening and surgical intervention may be helpful to the members of high-risk families.
