ABSTRACT
Objective:
Tumor-treating fields (TTFields) is a kind of non-invasive anti-mitotic tumor therapy, which has been approved for patients with newly diagnosed and recurrent glioblastoma. This study aims to explore the efficacy and safety of TTFields in high-grade gliomas in clinical practice settings.Methods:
The clinical data of 15 patients with recurrent glioma and 9 patients with newly diagnosed high-grade glioma admitted to our center from April 2019 to January 2021 were retrospectively analyzed. All patients accepted TTFields≥1 month. Follow-up was performed for 5.3 months (ranged from 2.3 to 10.7 months); Response Assessment in Neuro-Oncology Working Group (RANO) criteria was used to evaluate the glioma responses. The progression-free survival (PFS) and overall survival (OS) were calculated according to Kaplan-Meier method. Common Terminology Criteria for Adverse Events v5.0 (CTCAE v5.0) and TTFields related skin adverse reaction (dAE) criteria were used to evaluate the adverse events. Quality of life questionnaire-core 30 (QLQ-C30) and QLQ-brain cancer module (QLQ-BN20) questionnaires were used to evaluate the health-related quality of life (HRQoL). Treatment compliance was evaluated by data on the use of NovoTTF-200A devices, and calculated as a percentage of daily TTFields usage.Results:
The median duration of TTFields was 4.2 months (ranged from 1.0 to 10.7 months), with a median compliance rate of 91.5% (67.0%-97.0%). TTFields was used alone in 2 patients and used with combination of chemotherapy in 22 patients. From follow-up to April 2021, 14 patients had stable symptoms and 10 had disease progression (8 died). The median PFS and OS of recurrent patients were 5.9 months ( 95%CI 3.3-8.6 months) and 8.5 months ( 95%CI 3.2-13.8 months), respectively; and the median PFS and OS of newly diagnosed patients were both 10.7 months (without 95%CI). The common adverse events included grading 1 dAE (58.3%) and grading 2 dAE (12.5%), without grading 3 or 4 dAE, manifested as contact or allergic dermatitis, erosion, folliculitis and ulcers. And 87.5% patients had stable HRQoL.Conclusions:
The preliminary results showed that the survival of recurrent high-grade glioma patients treated by TTFields is similar to that reported in foreign literature; and the newly diagnosed patients need further survival follow-up. The patients' treatment compliance and safety are good. The dAE incidence (grading 1-2) is higher than that reported in the literature, and the toxicity was acceptable.
