香港,中国 - Media OutReach - 2018824 - 乳腺癌是中国女性发病率最高的癌症。 医生一般建议乳癌患者于手术切除肿瘤后服用他莫昔芬五年,减低复发机会。 但最近有研究显示,延长服用他莫昔芬至十年可进一步减低复发机会和死亡风险,延长患者的寿命。

延长荷尔蒙治疗 减低乳癌复发率

医生首选荷尔蒙治疗
香港临床肿瘤科专科医生梁广泉医生表示,治疗乳癌有三个主要方向,分别是全乳或局部乳房切除手术、放射治疗和药物治疗。 常见的药物治疗有荷尔蒙治疗、化学治疗、靶向治疗和免疫治疗。 在乳癌患者中,有三分之二对荷尔蒙受体呈阳性反应,适合接受荷尔蒙治疗。就此 ,他莫昔芬占据重要地位,它除了能抑制雌激素,达到控制肿瘤生长的效果,而且副作用比较少,可保存患者的生活素质,因此经常是医生的用药首选。

 

服用他莫昔芬十年 成国际新指南

梁医生表示,即使早期的乳癌患者已透过手术把肿瘤切除,癌细胞仍有机会残留体内,并经血  或淋巴系    其他器 官。 因此患者需在手术后服用他莫昔芬,减低复发机会。 英国及欧洲的研究数据显示,把服用他莫昔芬的年期从五年延长至十年, 可进一步减低乳癌患者复发的机会和死亡风险,而且不会明显增加副作用。
延长服用他莫昔芬能带来显著益处 ,因此这个做法已被不同国际指南采用,包括由美国临床肿瘤学会( American Society of Clinical Oncology)编制的《乳癌指南》。梁医生分享,曾有一个39岁的乳癌患者在确诊时已属第三期,并有淋巴转移的情况。 由于患者对荷尔蒙受体呈阳性反应,因此梁医生按最新的国际指南,建议患者服用原厂制造的他莫昔芬十年,减低复发风险和提升存活率。另有一位45岁的乳癌患者于确诊时癌细胞已转移至骨骼。考虑到患者病情的严重性,梁医生建议患者接受补骨针之余,亦建议她服用原厂他莫昔芬来控制病情。梁医生指,原厂他莫昔芬除了控制病情效果显著,它的副作用亦少,因此不会成为患者的额外负担,有效保存患者的生活质素,是治疗乳癌的可取之选。

 

原厂药物质素佳 安全性高有保证

梁医生提醒,原厂药物一般经过大型科研,获得正面的研究成果才获得专利权。 相反,仿制药物是在原厂药物的专利权过期后,仿照原厂药物成份生产,并没有进行科研或实验来验证药物的实质效能。加上它的制造过程、运送及储存的环境均没有受到严密的品质监控,因此无论药效、质或安全性也与原厂药物存在差异  梁医生认为原厂药物有保证,是医生的首选。 患者在选择两者时,可咨询主诊医生的专业意见。
