强度调节质子治疗显示对头颈部癌症有益

治疗完成,没有休息,住院;结果表明质子疗法可能用于管理头部和颈部肿瘤

在一项小型研究中,来自德克萨斯大学M188bet体育网址D安德森癌症中心的研究人员发现,93%接受多场优化强度调制质子治疗(MFO-IMPT)的头颈部癌症患者在治疗28个月后无癌。在某些情况下,标准辐射的典型副作用也减少了。这些初步结果提示质子治疗可能是头颈癌患者一种有效且毒性较小的治疗选择。

发表在《国际放射,肿瘤学,生物学,物理学杂志, the first of its kind study supports ongoing research by MD Anderson’s Proton Therapy Center regarding the benefits of proton therapy and, most recently, MFO-IMPT, which is best used to deliver a precise dose of protons to the most complicated tumors – ones that largely reside embedded in the nooks and crannies of the head and neck or at the base of the skull.

MFO-IMPT能够使周围的健康组织免受损害,并帮助保持生活质量,如神经认知功能、视觉、吞咽能力、听力、味觉和语言能力。目前用于头颈部癌症治疗的标准是调强放疗(IMRT),它会破坏癌变细胞和健康细胞,损害上面所列的一些功能。

前瞻性研究随访了15例头颈部肿瘤患者:10例鳞状细胞癌(SCC)和5例腺样囊性癌(ACC)经MFO-IMPT治疗。5例鳞状细胞癌患者在接受质子治疗前进行了诱导化疗。5例ACC患者均同时接受MFO-IMPT化疗。28个月时,所有10例鳞状细胞癌患者和4例ACC患者都没有癌变。结果还显示,副作用也减少了:

  • 所有患者完成治疗,没有任何中断,化疗剂量减少或住院。
  • 没有任何接受MFO-IMPT的患者,同时化疗经历了恶心或呕吐。
  • 此外,没有患者出现严重的皮炎(皮肤炎症)。

“Though early, this study provides the first evidence that proton therapy for head and neck cancers, which are becoming increasingly common, is safe and effective,” said Steven J. Frank, M.D., Medical Director of the Proton Therapy Center, associate professor of Radiation Oncology at MD Anderson. “As incidence of HPV-related head and neck cancers rise, it’s important to have treatment options that minimize long-term side effects. These patients are typically younger, are raising families and we hope have 30-40 years to look forward to as cancer survivors. The quality of those years is crucial.”

据该研究的主要作者Frank说,正在进行的研究将确定MFO-IMPT是否能够减少毒性并提高生存率。188bet体育网址

MD Anderson在2010年治疗了第一个MFO-IMPT患者;迄今为止,质子治疗中心大约有300名患者接受了这种形式的质子治疗,其中许多患者患有复杂的头颈部癌症。
