Laryngoscope:二甲双胍瞄准肿瘤能量源治疗头颈癌

2017-02-04 生物谷 生物谷

资深作者托马斯杰斐逊大学的医学肿瘤学系副教授和Sidney Kimmel癌症中心研究员Ubaldo Martinez-Outschoorn博士说:“此次研究是为了检验二甲双胍治疗头颈癌的疗效。令我们感到高兴的是,它最终使病人遭受的副作用更少。”Martinez-Outschoorn博士和他的同事认为,二甲双胍不仅改变了癌细胞赖以生存的通路,而且还改变了癌细胞微环境——包围和支持肿瘤的细胞

在过去的三年里,研究人员发现当患有头颈癌的糖尿病人服用二甲双胍时,其癌症治疗效果比非糖尿病人更好。为了进一步检验二甲双胍与抗癌疗效之间的关系,理解二甲双胍如何改变癌细胞的生物学特征,托马斯杰斐逊大学Sidney Kimmel癌症中心的研究人员对未患糖尿病的癌症病人服用二甲双胍前后的肿瘤细胞进行了检测。这项临床试验结果于近日发表在《The Laryngoscope》上。

资深作者托马斯杰斐逊大学的医学肿瘤学系副教授和Sidney Kimmel癌症中心研究员Ubaldo Martinez-Outschoorn博士说:“此次研究是为了检验二甲双胍治疗头颈癌的疗效。令我们感到高兴的是,它最终使病人遭受的副作用更少。”Martinez-Outschoorn博士和他的同事认为,二甲双胍不仅改变了癌细胞赖以生存的通路,而且还改变了癌细胞微环境——包围和支持肿瘤的细胞。杰斐逊大学耳鼻喉系副教授、论文第一作者Joseph Curry博士说:“因为肿瘤需要大量能量维持其快速增长,所以阻止能量产生会使得癌细胞对标准疗法更敏感。”

研究人员用二甲双胍治疗了39个病人,病人接受了糖尿病人短时间内服用的二甲双胍剂量的一半剂量,并在采用二甲双胍治疗前后检查了肿瘤样品。研究人员检测了细胞死亡、凋亡的分子标记物及可能使癌细胞对标准疗法更敏感的代谢通路,结果发现二甲双胍治疗的病人体内癌细胞凋亡程度显著增加,肿瘤周围的肿瘤相关成纤维细胞也有退化的迹象,表明这些细胞帮助癌细胞生长和转移的能力降低。同时,该研究中病人无高级别的副作用发生。

杰斐逊大学的病理学系、解剖学系和细胞生物学系副教授、外科病理学主任Madalina Tuluc博士说:“该研究证实了服用安全剂量的二甲双胍、也就是等同于糖尿病人服用的剂量或者比糖尿病人服用的更少的剂量对于头颈癌症患者有一定疗效。它改变了头颈癌的肿瘤生物学使癌细胞更容易被杀死。二甲双胍扰乱了癌细胞产生能量最有效的方式,以此切断了癌症的支持系统。”除此以外,其他的研究也表明二甲双胍对肿瘤有免疫疗法效果。

Martinez-Outschoorn博士说:“下一步就是在大量病人身上进行2期临床试验检测二甲双胍的剂量效应。”

二甲双胍真的是“神药”?

二甲双胍是一种好药,但绝非“神药”。人为的“造神”行为不利于该药的合理应用。二甲双胍在国内外多种指南中被推举为一线降糖药物。这样推荐的主要理由是该药具有肯定的降糖作用、低血糖风险小、对体重没有不利影响,并且价格较低廉。这些特点使得二甲双胍较其他传统降糖药物具有一定优势。然而,最近一些媒体报道中,屡屡将其称为“神药”,声称此药除了降糖作用外还能够降低心血管事件风险、抗癌、预防痴呆、抗衰老、延年益寿,

《循证临床实践指南》发表在《内科医学年鉴》上。在该指南中,美国医科大学(ACP)建议,当需要药物来改善2型糖尿病患者的高血糖时,医生应使用二甲双胍。 如果还需要一种口服药物来改善高血糖,ACP建议,医生们应该考虑添加磺脲类、噻唑烷二酮、SGLT-2抑制剂、DPP-4抑制剂,与二甲双胍配伍。 美国家庭医师学会批准了该指南。 “除非有禁忌症,二甲双胍是治疗糖尿病十分有效的药物。因为它效果佳,
