Case Report: Impact of gross total resection on survival in glioblastoma

Abstract

Glioblastoma (GBM), known for its aggressive behavior and dismal prognosis. Traditional therapeutic methods, including adjuvant chemotherapy and radiotherapy in conjunction with maximally safe surgical resection, are designed to prolong survival and alleviate symptoms. This case report investigates the relationship between survival outcomes in glioblastoma patients and gross total resection (GTR). A recurring seizure disorder manifested in a 58-year-old female patient presented with left-sided lower limbs weakness and occurred twice weekly for a maximum duration of 20 seconds; this condition necessitated hospitalisation and subsequent surgical intervention. A gross total resection was executed with success, resulting in the accomplishment of complete tumor excision. The patient received radiotherapy after a six-week regimen of temozolomide chemotherapy that followed the surgical removal of tumor. Notably, following treatment, the patient reported a substantial amelioration of symptoms and has maintained a 24-month survival rate thus far, with continuous follow-up. This case highlights the potential for enhanced survival outcomes in the treatment of glioblastoma when gross total resection (GTR) is followed by adjuvant chemo-radiotherapy.
