甲状腺癌的归类以及高危人群


    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">甲状腺癌(Thyroid Cancer)是一种起源于甲状腺滤泡上皮或滤泡旁上皮细胞的恶性肿瘤,<span style="color: black;">亦</span>是头颈部最为<span style="color: black;">平常</span>的恶性肿瘤。近年来,<span style="color: black;">全世界</span>范围内甲状腺癌的发病率增长<span style="color: black;">快速</span>,据全国肿瘤登记中心的数据<span style="color: black;">表示</span>,我国城市地区女性甲状腺癌发病率位居女性所有恶性肿瘤的第4位。我国甲状腺癌将以每年20%的速度<span style="color: black;">连续</span>增长。</p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1、甲状腺癌的<span style="color: black;">归类</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">按照</span>肿瘤起源及分化差异,甲状腺癌又分为:</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">甲状腺乳头状癌(papillary thyroid carcinoma,PTC)、</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">甲状腺滤泡癌(follicular thyroid carcinoma,FTC)、</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">甲状腺髓样癌(medullary thyroid carcinoma,MTC)、</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">甲状腺未分化癌(anaplastic thyroid cancer,ATC),</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">其中PTC最为<span style="color: black;">平常</span>,约占<span style="color: black;">所有</span>甲状腺癌的85%~90%,而PTC和FTC合<span style="color: black;">叫作</span>分化型甲状腺癌(differentiated thyroid carcinoma,DTC)。不同病理类型的甲状腺癌,在其发病机制、生物学<span style="color: black;">行径</span>、组织学形态、临床表现、治疗<span style="color: black;">办法</span>以及预后等方面均有<span style="color: black;">显著</span>不同。DTC生物<span style="color: black;">行径</span>温和,预后较好。ATC的恶性程度极高,中位<span style="color: black;">存活</span>时间仅7~10个月。MTC的预后居于两者之间。</p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2、<span style="color: black;">那些</span>人是甲状腺癌的高危人群?</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">有如下病史时<span style="color: black;">必须</span>高度<span style="color: black;">警觉</span>甲状腺癌,尽早进行筛查:</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">①童年期头颈部放射线照射史或放射性尘埃接触史;</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">②全身放射治疗史;</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">③DTC、MTC或多发性内分泌腺瘤病2型(MEN2型)、家族性多发性息肉病、某些甲状腺癌<span style="color: black;">综合症</span>[如多发性错构瘤<span style="color: black;">综合症</span> (multiple hamartoma syndrome)、Carney<span style="color: black;">综合症</span>、沃纳<span style="color: black;">综合症</span>(Werner syndrome)和加德纳<span style="color: black;">综合症</span>(Gardner syndrome)]等的既往史或家族史。</p>
    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic3.zhimg.com/80/v2-495eeb5f961a06352b71719680cb5d3a_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3、甲状腺癌的临床表现</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">a.症状</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">大<span style="color: black;">都数</span>甲状腺结节<span style="color: black;">病人</span><span style="color: black;">无</span>临床症状。<span style="color: black;">一般</span>在体检时<span style="color: black;">经过</span>甲状腺触诊和颈部超声<span style="color: black;">检测</span>而<span style="color: black;">发掘</span>甲状腺小肿块。合并甲状腺功能<span style="color: black;">反常</span>时可<span style="color: black;">显现</span>相应的临床表现,如甲状腺功能亢进或甲状腺功能<span style="color: black;">衰退</span>。晚期局部肿块<span style="color: black;">病痛</span>,可<span style="color: black;">显现</span>压迫症状,常可压迫气管、食管,使气管、食管移位。肿瘤局部侵犯重时可<span style="color: black;">显现</span>声音嘶哑、吞咽困难或交感神经受压<span style="color: black;">导致</span>霍纳<span style="color: black;">综合症</span>(Horner syndrome),侵犯颈丛可<span style="color: black;">显现</span>耳、枕、肩等处<span style="color: black;">病痛</span>等症状。颈淋巴结转移<span style="color: black;">导致</span>的颈部肿块在未分化癌<span style="color: black;">出现</span>较早。髓样癌<span style="color: black;">因为</span>肿瘤本身可产生降钙素和5-羟色胺,可<span style="color: black;">导致</span>腹泻、心悸、面色潮红等症状。</p>
