<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">能够</span><span style="color: black;">始终</span>化疗下去吗？答案当然是不<span style="color: black;">能够</span>，大部分人都是想减少化疗次数，很少有人<span style="color: black;">期盼</span>多化疗几次。今天<span style="color: black;">咱们</span>就来聊一聊，<span style="color: black;">大夫</span>是怎么制定化疗<span style="color: black;">方法</span>的，一个人<span style="color: black;">能够</span>最多做多少次化疗。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">第1</span>，<span style="color: black;">那些</span><span style="color: black;">病人</span><span style="color: black;">必须</span>化疗</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">现代的医学都是讲究证据的，<span style="color: black;">亦</span><span style="color: black;">便是</span>说，<span style="color: black;">咱们</span>要有数据的支持，化疗对这些病人有好处才行，<span style="color: black;">亦</span><span style="color: black;">便是</span>能够降低复发率，延长<span style="color: black;">存活</span>期。<span style="color: black;">因此</span>，医学上开展了<span style="color: black;">海量</span>的临床<span style="color: black;">实验</span>，将病人分成化疗组和不化疗组，化疗<span style="color: black;">倘若</span>能够延长寿命，降低复发，那这部分<span style="color: black;">病人</span>就<span style="color: black;">必须</span>做化疗。总的<span style="color: black;">来讲</span>，<span style="color: black;">初期</span>的<span style="color: black;">病人</span>不<span style="color: black;">必须</span>做化疗，<span style="color: black;">由于</span><span style="color: black;">初期</span>的<span style="color: black;">病人</span>，<span style="color: black;">存活</span>期<span style="color: black;">已然</span>很好了，化疗<span style="color: black;">不可</span>带来获益。<span style="color: black;">仅有</span>中晚期的<span style="color: black;">病人</span>，才<span style="color: black;">必须</span>做化疗。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">第二，<span style="color: black;">怎样</span>决定化疗次数</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">由于</span>化疗是有毒副<span style="color: black;">功效</span>的，<span style="color: black;">因此</span>，<span style="color: black;">大夫</span>会根据化疗药的代谢特点，副<span style="color: black;">功效</span>的<span style="color: black;">体积</span>，以及人类的承受能力，来决定化疗的次数和时间间隔。<span style="color: black;">非常多</span>化疗<span style="color: black;">药品</span>的毒副<span style="color: black;">功效</span>是累加的，是有剂量限制的，超过了<span style="color: black;">必定</span>的累积剂量，就<span style="color: black;">不可</span>再用了，那就<span style="color: black;">必须</span>更换其他的化疗<span style="color: black;">药品</span>。<span style="color: black;">针对</span>术后辅助化疗的<span style="color: black;">病人</span>，<span style="color: black;">通常</span>是做半年<span style="color: black;">上下</span>的化疗，不同的肿瘤，不同的化疗<span style="color: black;">药品</span>，化疗次数<span style="color: black;">亦</span>会不<span style="color: black;">同样</span>，<span style="color: black;">倘若</span>是三周一次的化疗<span style="color: black;">方法</span>，<span style="color: black;">通常</span>是化疗6至8次，<span style="color: black;">倘若</span>是2周一次的<span style="color: black;">方法</span>，<span style="color: black;">通常</span>是10到12次。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">而<span style="color: black;">针对</span>肿瘤复发转移的<span style="color: black;">病人</span>，<span style="color: black;">尤其</span>是<span style="color: black;">哪些</span><span style="color: black;">已然</span><span style="color: black;">无</span>手术机会，全身广泛转移的<span style="color: black;">病人</span>，可能<span style="color: black;">必须</span><span style="color: black;">连续</span>的化疗，我见过一个<span style="color: black;">病人</span>，是一个结肠癌的<span style="color: black;">病人</span>，术后化疗了8次，两年后<span style="color: black;">显现</span>肝转移，又化疗了6次，并且切除了肝转移瘤。又过了3年，肝脏和肺都发现了多发的转移瘤，<span style="color: black;">因为</span>转移瘤比较多，<span style="color: black;">已然</span><span style="color: black;">无</span>手术机会了，<span style="color: black;">病人</span><span style="color: black;">始终</span>在化疗加上靶向治疗，<span style="color: black;">日前</span><span style="color: black;">已然</span>化疗7次了，肿瘤<span style="color: black;">处在</span>稳定状态，<span style="color: black;">无</span><span style="color: black;">发展</span>。<span style="color: black;">病人</span>总共化疗了21次，<span style="color: black;">然则</span>身体<span style="color: black;">通常</span><span style="color: black;">状况</span>还是很好，<span style="color: black;">无</span><span style="color: black;">显现</span>严重的毒副<span style="color: black;">功效</span>。<span style="color: black;">然则</span>，化疗<span style="color: black;">方法</span><span style="color: black;">必须</span><span style="color: black;">持续</span>的更换和<span style="color: black;">调节</span>，<span style="color: black;">由于</span>化疗的副<span style="color: black;">功效</span>，以及耐药的现象。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">第三，化疗<span style="color: black;">方法</span><span style="color: black;">亦</span>是<span style="color: black;">始终</span>在变的</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">化疗<span style="color: black;">方法</span>是随着医学的进步，<span style="color: black;">始终</span>在<span style="color: black;">持续</span>变化的，<span style="color: black;">由于</span><span style="color: black;">持续</span>有新的效果更好，副<span style="color: black;">功效</span>更小的化疗药<span style="color: black;">显现</span>。<span style="color: black;">况且</span>，化疗周期<span style="color: black;">亦</span>可能会<span style="color: black;">出现</span>变化。<span style="color: black;">近期</span>就有<span style="color: black;">科研</span><span style="color: black;">表示</span>，<span style="color: black;">针对</span>危险度没<span style="color: black;">那样</span>高的结直肠癌，可能只<span style="color: black;">必须</span>化疗三个月就<span style="color: black;">能够</span>了，化疗三个月<span style="color: black;">能够</span>达到和半年<span style="color: black;">同样</span>的效果。<span style="color: black;">因此</span>，<span style="color: black;">大夫</span>们<span style="color: black;">必须</span><span style="color: black;">持续</span>的学习，更新自己的知识，改变自己的医疗策略。</p>总而言之，<span style="color: black;">针对</span>术后辅助化疗的<span style="color: black;">病人</span>，化疗次数是有限制的，不<span style="color: black;">必须</span><span style="color: black;">始终</span>化疗，<span style="color: black;">由于</span>过度的化疗会带来严重的副<span style="color: black;">功效</span>，会得不偿失。<span style="color: black;">针对</span>肿瘤晚期，姑息性化疗的<span style="color: black;">病人</span>，可能<span style="color: black;">必须</span><span style="color: black;">长时间</span>化疗，就<span style="color: black;">必须</span><span style="color: black;">选取</span>比较温和，副<span style="color: black;">功效</span>小的化疗<span style="color: black;">药品</span>，例如口服化疗药<span style="color: black;">长时间</span>维持，<span style="color: black;">或</span><span style="color: black;">选择</span>副<span style="color: black;">功效</span>更小的靶向治疗和内分泌治疗。<span style="color: black;">大夫</span>会<span style="color: black;">按照</span><span style="color: black;">病人</span>的病情，身体<span style="color: black;">状况</span>，<span style="color: black;">选取</span>合适的化疗<span style="color: black;">方法</span>和周期。
