The complexity of cancer care may affect patients’ financial toxicity more than we’ve realized. Many patients struggle with the economic burden of out-of-pocket spending for cancer care, including insurance copayments, transportation, and reduced income, as well as their psychological burden of worry and coping with less funds for food and medications. Multimodality treatments, maintenance and ongoing therapies for metastatic disease, and geographic factors such as travel for clinical trials and specialized services or paying for out-of-network care can put patients’ finances in a deeper hole. The adverse implications are significant: decreased quality of life, increased anxiety and depression, lower adherence to prescribed medications and oncology care, and reduced survival.
