Chordomas are rare tumors of the skull base and the spine. Treatment is difficult since conventional radiotherapy or chemotherapy have only limited effects.
A patient with a sacral chordoma and pulmonary metastases received initial surgery and radiotherapy for a local recurrence. After 11 months another local recurrence as well as a progression of the pulmonary metastases was documented. As tumor biopsies revealed the expression of the EGF receptor an individual treatment approach with a combination of cetuximab and gefitinib was performed.
Under the treatment with cetuximab/gefitinib the local recurrence and the pulmonary metastases showed a partial response over the follow-up period of 9 months. To date no treatment failure was observed.
The inhibition of the EGF pathway seems to be an effective measure in the treatment of a chordoma. Further follow-up will have to prove the long-term efficiency.
脊索瘤是颅底和脊柱的罕见肿瘤。由于传统放疗或化疗效果有限,治疗困难。
一名患有骶骨脊索瘤和肺转移的患者因局部复发接受了初次手术和放疗。11个月后,记录到又一次局部复发以及肺转移进展。由于肿瘤活检显示表皮生长因子受体表达,采用西妥昔单抗和吉非替尼联合的个体化治疗方案。
在西妥昔单抗/吉非替尼治疗下,局部复发和肺转移在9个月的随访期内显示部分缓解。迄今为止,未观察到治疗失败。
表皮生长因子途径的抑制似乎是治疗脊索瘤的有效措施。进一步随访将必须证明其长期疗效。
