2021 WHO grade 2 cases from cluster 1 had worse progression-free survival (PFS) a and overall survival (OS) b compared to grade 2 cases from cluster 2. No significant difference was found between 2021 WHO grade 3 cases from cluster 1 and 2 in terms of PFS c, however grade 3 cases from cluster 1 had significantly worse OS compared to grade 3 cases from cluster 2 d. No significant difference was found between 2021 WHO grade 4 cases from cluster 1 and 2 in terms of PFS e or OS f
