Anaplastic astrocytomas are progressive brain tumors with a tendency to infiltrate the surrounding tissue. Recurrence is very common, with recurrent tumors being extremely refractory to existing therapies. Case Presentation: A 33-year-old woman presented with a history of an unprovoked fall, followed by seizures. An MRI scan revealed a mass in the fronto-temporo-parietal region of the brain, suggesting a primary tumor. She underwent craniotomy and surgical debulking of the tumor. The histology of the tumor tissue revealed an anaplastic astrocytoma. Follow-up MRI scans indicated the presence of a residual, rapidly progressing tumor. A 6-week course of fractionated radiation and concurrent chemotherapy with Temodar(R) (temozolomide capsules) did not stop tumor progression. Intervention: Due to the failure of conventional therapies in preventing rapid disease progression, the patient volunteered to undergo a 28-day course of Sequentially Programmed Magnetic Field (SPMF) therapy. RESULTS: Immediate post-therapy MRI scan showed a cessation of tumor growth, and follow-up imaging at 6, 12, 24 and 36 months revealed a gradual but steady decrease in the size of the tumor. The patient reported an alleviation of clinical symptoms and a subjective improvement in the quality of life at 6, 12, 24 and 36 months following SPMF therapy. CONCLUSION: The remarkable improvement of this patient suggests that SPMF therapy may be a valuable option for anaplastic astrocytoma, especially in recurrent and rapidly progressing tumors.
间变性星形细胞瘤是一种进行性脑肿瘤,有浸润周围组织的倾向。复发非常常见,复发性肿瘤对现有治疗极难治愈。病例报告:一名33岁女性,有不明原因跌倒史,随后出现癫痫发作。磁共振成像(MRI)扫描显示脑额颞顶叶区域有一个肿块,提示原发性肿瘤。她接受了开颅手术及肿瘤减瘤手术。肿瘤组织的组织学检查显示为间变性星形细胞瘤。后续的MRI扫描显示存在残留的、快速进展的肿瘤。一个为期6周的分次放疗及与替莫唑胺胶囊同步化疗的疗程未能阻止肿瘤进展。干预措施:由于传统治疗未能阻止疾病快速进展,患者自愿接受为期28天的序贯程控磁场(SPMF)治疗。结果:治疗后即刻的MRI扫描显示肿瘤生长停止,在6个月、12个月、24个月和36个月的随访成像显示肿瘤大小逐渐但稳定地减小。患者报告在接受SPMF治疗后的6个月、12个月、24个月和36个月,临床症状有所缓解,生活质量有主观改善。结论:该患者的显著改善表明,SPMF治疗可能是间变性星形细胞瘤的一种有价值的选择,尤其是对于复发性和快速进展性肿瘤。
