ABSTRACT
BACKGROUND:
A more extensive surgical resection of glioma contributes to improved overall survival (OS) and progression-free survival (PFS). However, some patients miss the chance of surgical resection when the tumor involves critical structures.PURPOSE:
The present study aimed to assess the feasibility of neoadjuvant 125I brachytherapy followed by total gross resection for initially inoperable glioma.METHODS:
Six patients diagnosed with inoperable glioma due to invasion of eloquent areas, bihemispheric diffusion, or large tumor volume received 125I brachytherapy. Surgical resection was performed when the tumor shrank, allowing a safe resection, assessed by the neurosurgeons. Patients were followed up after surgery.RESULTS:
Shrinkage of the tumor after adjuvant 125I brachytherapy enabled a total gross resection of all six patients. Four patients were still alive at the last follow-up, with the longest survival time of more than 50 months, two of which returned to everyday life with a KPS of 100. Another two patients had neurological injuries with KPSs of 80 and 50, respectively. One patient with grade II glioma died 34 months, and another with grade IV glioma died 40 months after the combined therapy.CONCLUSIONS:
In the present study, the results demonstrated that 125I brachytherapy enabled a complete resection of patients with initially unresectable gliomas. 125I brachytherapy may offer a proper neoadjuvant therapy method for glioma.Palavras-chave
