The aim of this study was to describe the epidemiological and survival features of patients with glioblastoma multiforme treated in 2 health care scenarios—public and private—in Brazil.Methods
We retrospectively analyzed clinical, treatment, and outcome characteristics of glioblastoma multiforme patients from 2003 to 2011 at 2 institutions.Results
The median age of the 171 patients (117 public and 54 private) was 59.3 years (range, 18–84). The median survival for patients treated in private institutions was 17.4 months (95% confidence interval, 11.1–23.7) compared with 7.1 months (95% confidence interval, 3.8–10.4) for patients treated in public institutions (P < .001). The time from the first symptom to surgery was longer in the public setting (median of 64 days for the public hospital and 31 days for the private institution; P = .003). The patients at the private hospital received radiotherapy concurrent with chemotherapy in 59.3% of cases; at the public hospital, only 21.4% (P < .001). Despite these differences, the institution of treatment was not found to be an independent predictor of outcome (hazard ratio, 1.675; 95% confidence interval, 0.951–2.949; P = .074). The Karnofsky performance status and any additional treatment after surgery were predictors of survival. A hazard ratio of 0.010 (95% confidence interval, 0.003–0.033; P < .001) was observed for gross total tumor resection followed by radiotherapy concurrent with chemotherapy.Conclusions
Despite obvious disparities between the hospitals, the medical assistance scenario was not an independent predictor of survival. However, survival was directly influenced by additional treatment after surgery. Therefore, increasing access to resources in developing countries like Brazil is critical.
