“皮肤毒性反应越重,靶向治疗效果越好?”是真的吗?肿瘤专家为你详细解答

2020-08-05 佚名 四川省肿瘤医院

靶向药物挽救了许多肿瘤患者的生命,同时也让很多患者因为严重皮疹而痛苦不堪,为什么会出现皮疹咧?

靶向药物挽救了许多肿瘤患者的生命,同时也让很多患者因为严重皮疹而痛苦不堪,为什么会出现皮疹咧?

有传言说“皮肤毒性反应严重程度与靶向治疗效果有关系,皮肤不良反应越重,靶向治疗效果越好”,真的是这样吗?下面请听专家给大家讲一讲。

为啥长皮疹?

因为临床上用的大多数靶向药物是一种特异性的分子靶向药物,被称作表皮生长因子受体抑制剂(EGFRIs),表皮生长因子(EGFR)在表皮内发挥着重要作用,促进表皮细胞生长、抑制分化、保护细胞免受紫外线损伤、抑制炎症并加速伤口愈合。

也就是说,不光是肿瘤细胞表面有表皮生长因子,在正常皮肤上也有这个东东,当用了这类靶向药以后,肿瘤细胞不长了,正常皮肤细胞也不长了,皮肤的其他正常功能也没有了!

所以目前认为,皮肤的角质形成细胞是靶向药物皮肤不良反应发生的主要靶点。靶向药物通过竞争性抑制ATP与受体胞浆区的结合,从而阻止磷酸化和激酶的活性,影响角质化细胞的增生、分化、迁移以及粘附,从而导致丘疹脓疱的形成及干燥症的发生。这样说是不是明白多了呢。

哪些靶向药最容易发生皮疹?

大部分靶向药其实都有可能发生皮疹,痤疮痒皮疹是靶向药物常见的副作用之一,其中特罗凯(厄洛替尼)、易瑞沙(吉非替尼)、凯美纳(埃克替尼)、克唑替尼等皮疹发生率较高。

靶向药所致皮疹长啥样子?

肺癌靶向药物对皮肤的毒性较为明显,常出现痤疮痒皮疹、瘙痒、甲沟炎、皮肤皲裂、溃烂,或手足综合征的表现。大多患者吃靶向药10天开始出皮疹,刚开始是发红,然后有的起包,带白尖,洗脸时有可能白尖会破,出血,不痒,大多数患者表现为全身皮肤粘膜广泛的药物性滤泡疹。由于靶向药物不同,皮疹分布也不一样。如口服易瑞沙的,皮疹主要集中在脸部;口服特罗凯的,首次服用后,皮疹首先大片出现于背部,约10天左右皮疹最严重。

皮疹传染不?

靶向治疗引起的皮疹,往往看着吓人,但它没有传染性,一段时间或者停药后会自行消退。

如何预防和处理皮疹?

1.靶向药物正确服用:餐前1小时或者餐后2小时服用可预防皮疹。

2.常规皮肤预防:建议患者减少日晒时间,注意避光。由于靶向药物所导致的皮疹多属于光敏性皮疹,见光或者暴露于日光部分的皮疹会更严重。其次,每天保持皮肤清洁及干燥部位皮肤湿润。勿接触碱性和刺激性强的洗漱用品,沐浴后涂温和的润肤露或霜剂、维生素E软膏以预防皮肤干燥。

3.药物预防:从使用靶向药物第一天开始,遵医嘱使用预防皮疹药物,如米诺环素100mg,分次口服,并持续观察皮疹发生情况。皮疹严重者可遵医嘱进行靶向药物剂量调整或者暂停用药(这种情况必须由主管医生判定)。

4.皮疹处理:肺癌靶向药物引起的皮疹,分为轻度、中度和重度。轻度皮疹一般局限于头面部和躯干部,基本上没有主观症状,对生活影响不大,也不会继发感染,不需特别处理,以观察为主;但是,重度皮疹对病人的生活质量影响很大,需要积极配合医生处理。

皮疹护理需注意些什么?

1.由于人手上的细菌往往比空气中还多,建议患者不要用手抓挠皮疹处,避免引起感染。

2.由于靶向药物破坏了皮肤的防晒功能。建议患者最好避光,出门带帽子、涂防晒霜,做好皮疹处的防晒。

3.建议用清水清洗皮疹处,不要用肥皂、沐浴露等刺激性洗浴产品,不要用力搓洗,洗澡也不宜太勤,夏季1-2天洗1次,冬季每周洗1-2次。

4.保持皮肤湿润,面部及身体处皮肤涂抹保湿乳液,防止皮肤干燥。

5.少吃海鲜等易过敏的食物,避免加重皮疹的发生。

6.同时使用其它药物时,注意观察药物之间相互作用,避免加重皮疹发生。

7.出现皮肤异常紧急情况时,请及时联系医生,配合处理。
