A multivariate analysis revealed that tumour size, nodal status and FHL1 were independent poor prognostic factors of DFS and OS in breast cancer patients treated with radiotherapy (Supplementary Tables 1 and 2), and tumour size and FIGO stage were independent poor prognostic factors in cervical cancer patients treated with radiotherapy (Supplementary Tables 3 and 4). Here, FHL1 is linked to breast carcinoma.
