Background: Glioblastoma (GBM) is the most common primary malignant brain tumor in adult. Its incidence increases with age and nearly half of the all newly diagnosed GBM cases are older than 65 years. Management of GBM in elderly is challenging and recurrence poses further challenge. This article aims to review the literature, evaluate the various options, and to decide the treatment plan in elderly cases with GBM recurrence.
Methods: A systemic search was performed with the phrase "recurrent GBM (rGBM) in elderly and management" as a search term in PubMed central, Medline, and Embase databases to identify all the articles published on the subject till February 2022. The review included peer-reviewed original articles, review articles, clinical trials, and keywords in title and abstract.
Results: Out of 473 articles searched, 15 studies followed our inclusion criteria and were included in this review. In 15 studies, ten were original and five were review articles. The minimum age group included in these studies was ≥65 years. Out of 15 studies, eight studies had described the role of resurgery, four chemotherapy, three resurgery and/or chemotherapy, and only one study on role of reradiotherapy in patients with rGBM. Out of eight studies described the role of resurgery, six have mentioned improved survival and two have no survival advantage of resurgery in cases of rGBM.
Conclusion: Resurgery is the main treatment option in selected elderly rGBM cases in good performance status. In patients with poor performance status, chemotherapy has better post progression survival than best supportive care.
