New Approach for Enhancing Survival in Glioblastoma Patients: A Longitudinal Pilot Study on Integrative Oncology

Background: Glioblastoma (GBM IDH-wildtype WHO 2021) is an aggressive central nervous system malignancy with a poor prognosis despite standard therapy. Integrative oncology approaches involving natural compounds have shown potential in preclinical studies to enhance the efficacy of chemoradiotherapy. Methods: This prospective, longitudinal observational pilot study, lacking a randomized control group, followed 72 newly diagnosed glioblastoma patients (diagnosed by histological examination and MGMT promoter molecular study alone, grade 4 glioma patients) treated with the STUPP protocol. This group could voluntarily opt to receive integrative therapy (IT), which included polydatin, curcumin, and Boswellia serrata, in addition to standard care. Survival outcomes were compared between IT-adherent and non-adherent patients. Multivariate Cox regression was employed to adjust for potential confounders, including age, extent of surgical resection, and corticosteroid use. Results: The median overall survival (OS) for the entire cohort was 13.3 months. Patients who adhered to IT (n = 60) had a median OS of 25.4 months, which increased to 34.4 months for those who underwent gross total resection. The non-IT group (n = 12) exhibited a median OS of 10.6 months. Multivariate analysis confirmed that IT adherence and the extent of resection were independent predictors of prolonged survival (p < 0.05). No severe adverse events were reported with IT. Conclusions: Integrative therapy combining polydatin, curcumin, and Boswellia serrata with standard treatment would appear to be associated with prolonged survival in glioblastoma patients, particularly among those who underwent gross total resection. However, the small size of the control group, the absence of randomization, and the inclusion solely of primary glioblastoma limit the generalizability of these findings. These results underscore the need for further investigation through randomized controlled trials.
