“…These studies have shown impacts related to out-of-pocket costs (OOPC) [1][2][3][4][5][6][7], lost income for patients [8-14,15 ,22,23,31], colorectal [22,23,32,33], lung [22,23], prostate [3,22,23,25], other solid tumours [16,21,34] as well as hematologic malignancies [26]. These data suggest that having metastatic disease [34], receiving immunotherapy treatment [30] and the specific tumour types [28] increases financial toxicity. A recent review by Longo et al [27 & ] illustrates that these costs continue to be of concern in a variety of countries, including: Canada, Australia, Ireland, UK, Germany, France, Denmark, the Netherlands, Finland, Malaysia and South Korea, despite largely public-funded healthcare systems.…”
