Despite optimal treatment of post-operative radiotherapy and chemotherapy for newly diagnosed high-grade astrocytoma, nearly all patients eventually recur. However, the efficacy of reoperation for recurrent astrocytoma is still debatable as to different surgical indications. To investigate the therapeutic effect of reoperation on patients with recurrent high-grade astrocytoma more objectively, a retrospective case-matched study was carried out. The clinical data of 63 cases of recurrent high-grade astrocytoma treated between January 2006 and December 2008 were studied. A total of 21 cases received reoperation immediately after tumor recurrence, while 42 cases without reoperation were matched by gender, age, Karnofsky Performance Scale (KPS) score, histopathology, recurrent interval after the first operation, extent of initial surgery, adjuvant treatment and characteristics of recurrent tumor. The study showed that the median survival time was 7 months in the reoperation group, while in non-reoperation group, it was 4 months. There was significant difference on univariate analysis (P < 0.001). Moreover, the median duration time of progression-free survival (PFS) after tumor recurrence was significantly (P < 0.001) longer in the reoperation group (5 months) than that in the non-reoperation group (2.5 months). The prognostic factors of recurrent high-grade astrocytoma included reoperation, KPS score and tumor location. It was indicated that reoperation could prolong the survival time and improve the quality of survival in patients of recurrent high-grade astrocytoma.
