Abstract Aims Data on the treatment and outcomes of patients with primary brain tumours in England is sparse. The GlioCova project uses linked national data from England to explore the incidence, treatment, outcomes, and treatment costs of all adult brain tumour patients in all 50,000 patients in England from 2013 – 2018. Here we present initial results from patients with glioblastoma (GBM). Method We used a linked dataset from the national cancer registration system in England including all adult patients diagnosed with a malignant or benign brain tumour between 2013 and 2018 (51,775 patients in total). Glioblastoma patients were selected based on ICD-10 codes (C70, C71, C72), morphology codes (9440, 9441, 9442), and grade (G4, G3, GX and NA) from the national cancer registry. We extracted data on treatment (radiotherapy, chemotherapy, brain surgery or biopsy) and measured how many patients who had adjuvant Temozolomide completed 6 cycles. Results We identified 15,294 glioblastoma patients. Most had glioblastoma morphology (14,924), followed by gliosarcoma (264) and giant cell glioblastoma (106). Almost all had a cranial tumour (C71) while 17 had a tumour originating in the spinal cord, cranial nerves or other part of central nervous system (C72). Median age was 66 (IQR=17) and 60% were male. 51.9% (7,935) underwent surgery; an additional 18.2% (2,784) had a biopsy; 3,701 (24.2%) out of 15,294 patients received radiotherapy (only) and 316 (2.1%) received chemotherapy (only). 5,520 (36.1%) received both radiotherapy and chemo. Out of 4,101 GBM patients receiving temozolomide after radiotherapy, only 1,535 (37.4%) completed 6 cycles. The 7,935 GBM patients who had surgery had a median length of stay in hospital of 5 days (IQR=6) while those that had a biopsy had a median of 3 days (IQR=6). Conclusion We have presented a description of treatment of all GBM patients in England over a five-year period. This is the first time we have been able to understand detailed treatment patterns at a national scale, and significantly extends previous analyses. Further work will look at patient safety indicators, variation across centres and costs of treatment. Acknowledgements We would like to thank the GlioCova Expert Advisory Group for their input and discussion. This work uses data provided by patients and collected by the NHS as part of their care and support.
