BACKGROUND/AIM: Patients with brain metastases from thyroid cancer are extremely rare. This study evaluated clinical factors for survival following whole-brain radiotherapy (WBRT) alone.
In six patients, the following factors were analyzed for survival: Regimen of WBRT (5×4 Gy vs. 10×3 Gy), gender, age (≤55 vs. ≥56 years), Karnofsky performance score (KPS) (60% vs. 70-80%), number of brain lesions (2-3 vs. ≥4) and number of extra-cranial metastatic sites (one vs. more than one).
KPS 70-80% (p=0.036) and involvement of only one extra-cranial site (p=0.018) were associated with better survival on univariate analysis. On Cox regression analysis, KPS (p=0.14) and number of extra-cranial sites (p=0.14) showed trends for association with survival. In patients with KPS 70-80% and only one extra-cranial site, 6-month survival was 100%, no patient with KPS 60% and more than one extra-cranial site survived to 6 months.
KPS and number of involved extra-cranial metastatic sites were associated with survival and may be helpful for individualizing therapy in patients with brain metastases from thyroid cancer.
背景/目的：甲状腺癌脑转移患者极为罕见。本研究评估了单纯全脑放疗（WBRT）后的生存临床因素。
对6例患者的以下因素进行生存分析：WBRT方案（5×4 Gy与10×3 Gy）、性别、年龄（≤55岁与≥56岁）、卡诺夫斯基体能状态评分（KPS）（60%与70 - 80%）、脑转移瘤数量（2 - 3个与≥4个）及颅外转移部位数量（1个与多于1个）。
单因素分析显示，KPS 70 - 80%（p = 0.036）及仅1个颅外转移部位（p = 0.018）与较好的生存相关。Cox回归分析显示，KPS（p = 0.14）及颅外转移部位数量（p = 0.14）显示出与生存相关的趋势。KPS 70 - 80%且仅1个颅外转移部位的患者，6个月生存率为100%，无KPS 60%且多于1个颅外转移部位的患者存活至6个月。
KPS及颅外转移部位数量与生存相关，可能有助于甲状腺癌脑转移患者的个体化治疗。
