<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">人们<span style="color: black;">一般</span>所说的 “肝癌”,<span style="color: black;">指的是</span>原发于肝脏的恶性肿瘤,即原发性肝癌。</span></strong><span style="color: black;">出现</span>于其他器官而转移至肝脏的恶性肿瘤则<span style="color: black;">叫作</span>为“继发性肝癌”,<span style="color: black;">这里</span>不做讨论。</p><img src="https://mmbiz.qpic.cn/mmbiz_png/lQzXWpmM34WJSfADD6Qhla29n9oxbR6HMiaAPia1H8GUrkKz9rFIEX3N0LJFatv0tl7uAONqoj5OawYj2ibCicZiaiaw/640?wx_fmt=png&from=appmsg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">临床上,经常有<span style="color: black;">病人</span>提出疑问:“都是肝癌,<span style="color: black;">为何</span>我的<span style="color: black;">检测</span>项目和治疗<span style="color: black;">方法</span>跟别人不<span style="color: black;">同样</span>呢?”</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">其实,原发性肝癌<span style="color: black;">按照</span>显微镜下的形态差异,<span style="color: black;">或</span>说<span style="color: black;">按照</span>肿瘤起源细胞的不同分为<strong style="color: blue;"><span style="color: black;">3种类型:肝细胞癌、肝内胆管癌和混合型肝细胞癌-胆管癌</span></strong>。三者在发病机制、生物学<span style="color: black;">行径</span>、病理组织学、诊疗<span style="color: black;">办法</span>等方面差异<span style="color: black;">很强</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">肝脏的生理功能及</strong><strong style="color: blue;">其组织学<span style="color: black;">形成</span></strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肝脏是人体最大的消化腺体。肝细胞<span style="color: black;">每日</span>能产生600~1000毫升胆汁,<span style="color: black;">做为</span><strong style="color: blue;"><span style="color: black;">消化液参与脂类<span style="color: black;">食品</span>的消化;肝合成多种蛋白质等多类物质,<span style="color: black;">同期</span>还参与糖、脂类、激素和<span style="color: black;">药品</span>的代谢与解毒。</span></strong>
</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">显微镜下,成千上万个肝细胞<span style="color: black;">形成</span>1个肝小叶,<span style="color: black;">做为</span>肝脏的基本结构单位,成人肝<span style="color: black;">大概</span>50万~100万个肝小叶。在肝小叶中央以及周边还有许多微型脉管和血窦等结构,可为肝细胞<span style="color: black;">供给</span>营养,<span style="color: black;">同期</span>将各类物质<span style="color: black;">传送</span>至肝细胞进行代谢;<span style="color: black;">同期</span>,肝细胞周边有许多微细的<span style="color: black;">胆怯</span>管,这些微小的脉管和胆管逐级汇合,<span style="color: black;">最后</span>形成粗大的管道(门静脉、动脉、胆管)由肝门进出肝脏,肝细胞分泌的胆汁<span style="color: black;">最后</span>经胆总管流入肠道参与消化,<span style="color: black;">或</span>进入胆囊储存起来。<span style="color: black;">能够</span>把肝脏比喻成一棵枝繁叶茂的 “大树”:把肝细胞<span style="color: black;">或</span>肝小叶想象成树叶,将肝细胞间的各类脉管、血窦以及<span style="color: black;">胆怯</span>管想象成树叶上的经络,这些细枝末节层层递进,逐级汇合成更大的树枝,众多粗壮的树枝<span style="color: black;">最后</span>形<span style="color: black;">成为了</span>树干。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">从<strong style="color: blue;"><span style="color: black;"><span style="color: black;">出现</span>部位</span></strong>来区分3种类型的肝瘤:<span style="color: black;">肝细胞癌<span style="color: black;">出现</span>于“树叶”,肝内胆管癌则<span style="color: black;">出现</span>于树叶间的经络<span style="color: black;">或</span>细小的树枝,而混合型肝癌则<span style="color: black;">出现</span>于树叶与树枝交汇处,</span>是<span style="color: black;">拥有</span>2种<span style="color: black;">成份</span>的癌变,<span style="color: black;">同期</span>具备这2种肿瘤的生物学特征。<span style="color: black;">因此呢</span>,本文<span style="color: black;">针对</span>混合型肝癌,<span style="color: black;">再也不</span>单独<span style="color: black;">陈列</span>比较。接下来来<span style="color: black;">瞧瞧</span>肝细胞癌与肝内胆管癌两者在<strong style="color: blue;"><span style="color: black;">发病危险<span style="color: black;">原因</span>、血清学标志物、临床表现、诊疗模式等方面</span></strong>的不同。</p>
