Characterizing Non-predictable Breakthrough Cancer Pain in frmale cancer patients: a secondary analysis from IOPS-MS study

IOPS-MS was a big multicentric study with the aim of characterizing BTcP in a large number of patients belonging to different settings and assessing possible factors influencing its development. Moreover, NP-BTcP topic was addressed elsewhere [https://doi.org/10.3390/cancers13164018]. The principal aim of this work is to characterize breast cancer (BC) patients compared with no-female-specific cancers (no-FSC). The importance of such focus lies on detecting main behavior of a hormone-dependent cancer type with respect to tumors which are not specific for women.
