<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">胰腺癌,号<span style="color: black;">叫作</span>“癌症之王”,开玩笑的说,算是<span style="color: black;">疾患</span>里的“王中之王”了,<span style="color: black;">这般</span>的<span style="color: black;">叫作</span>号让人更加<span style="color: black;">没</span>法<span style="color: black;">忽略</span>胰腺癌这个<span style="color: black;">疾患</span>,<span style="color: black;">为何</span>会有如此威名?</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这就要从胰腺癌的预后讲起,胰腺癌是一种预后极差的<span style="color: black;">疾患</span>,<span style="color: black;">按照</span>《柳叶刀》杂志记载,胰腺癌确诊后的五年<span style="color: black;">存活</span>率不到10%,<span style="color: black;">况且</span>近年来发病率越来越高,<span style="color: black;">按照</span>世界卫生组织统计,2020年我国因胰腺癌死亡的病例人数排名第六位,仅次于肺癌、肝癌、胃癌、食道癌和结直肠癌。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">患胰腺癌的<span style="color: black;">危害</span>随年龄增长而<span style="color: black;">增多</span>,大<span style="color: black;">都数</span>病例<span style="color: black;">出现</span>在65岁以后,40岁前发病者非常少见,男性比女性患病几率高,BMI指数大于35的人士,患病<span style="color: black;">危害</span>会<span style="color: black;">增多</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">大约25%的病例与吸烟<span style="color: black;">相关</span>,这是最确定的可避免<span style="color: black;">原因</span>,<span style="color: black;">长时间</span>吸烟者比不吸烟者<span style="color: black;">危害</span>高约一倍,<span style="color: black;">危害</span>随吸烟年限增长而<span style="color: black;">增多</span>,戒烟后<span style="color: black;">危害</span>缓慢下降,大约20年<span style="color: black;">上下</span><span style="color: black;">能够</span>恢复到与非吸烟者<span style="color: black;">危害</span>相同的水平。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">5%-10%与遗传基因<span style="color: black;">相关</span>,<span style="color: black;">倘若</span>不止一个一级亲属<span style="color: black;">身患</span>该<span style="color: black;">疾患</span>,则<span style="color: black;">危害</span>大大<span style="color: black;">增多</span>,<span style="color: black;">意见</span>遗传<span style="color: black;">危害</span>较高的人群进行<span style="color: black;">初期</span>胰腺癌筛查。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">胰腺癌的临床症状</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">胰腺癌起病隐匿且症状不典型,这个特点与结直肠癌<span style="color: black;">非常</span><span style="color: black;">类似</span>,<span style="color: black;">因此</span>都非常容易<span style="color: black;">导致</span>确诊即晚期的现象,<span style="color: black;">必须</span>时常<span style="color: black;">重视</span><span style="color: black;">初期</span>不<span style="color: black;">显著</span>的症状,<span style="color: black;">那样</span>,胰腺癌有<span style="color: black;">那些</span>症状呢?</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">上腹或背部<span style="color: black;">病痛</span>,<span style="color: black;">夜晚</span><span style="color: black;">病痛</span>更加<span style="color: black;">显著</span>,随着时间推移会加重,向前弯曲<span style="color: black;">能够</span>缓解;恶心、呕吐、饱腹感,便秘,大便黏腻<span style="color: black;">很难</span>冲走,不明<span style="color: black;">原由</span>的体重减轻,腹部包块,黄疸,焦虑,抑郁,新发糖尿病或原有糖尿病的病情加重、静脉血栓等症状。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">胰腺癌的诊断</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">日前</span>胰腺癌诊断的金标准仍旧是活检技术,腹部超声<span style="color: black;">检测</span>并不全面,可能<span style="color: black;">没</span>法看到<span style="color: black;">有些</span>很小的肿瘤,<span style="color: black;">然则</span><span style="color: black;">能够</span>识别腹腔中的积液,CT<span style="color: black;">能够</span><span style="color: black;">表示</span>有<span style="color: black;">没</span>肿瘤或潜在的可切除肿瘤,磁共振胰胆管<span style="color: black;">影像</span>和内窥镜<span style="color: black;">能够</span>用于<span style="color: black;">疾患</span>分期或检测CT不可见的小肿瘤,梗阻性黄疸<span style="color: black;">病人</span>首选<span style="color: black;">办法</span>是经内镜逆行胰胆管造影。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">胰腺癌病例中有90%为胰腺导管腺癌,5%<span style="color: black;">上下</span>为胰腺神经内分泌肿瘤,1%-2%为胰腺腺泡细胞癌,1%-4%为腺鳞癌。胰腺癌<span style="color: black;">一般</span>在CT扫描后进行分期,基于肿瘤<span style="color: black;">体积</span>和扩散、转移进行分期。</p>
