Chemotherapy and Targeted Therapy Near the end of life Affects Aggressiveness of Palliative Care

Background: In patients with advanced cancer, considering the increased application of targeted therapy and immunotherapies, we explored the difference between indicators of chemotherapy and targeted therapy in the last month of life.Methods: Electronic medical data of patients who died from metastatic cancer and received targeted therapy and palliative chemotherapy from April 2007 to December 2018 at the Department of Integrated Therapy, Fudan University Shanghai Cancer Center were analyzed retrospectively. To determine those variables that were judged to be independent predictors of the use of palliative chemotherapy and targeted therapy, and the differences between them, univariate and multivariate analyses were used.Results: Of the 585 patients included in the study, 87 (14.9%) received palliative chemotherapy and 125 (21.3%) underwent targeted therapy during the last month. Patients who received continued chemotherapy within the last month were subjected to more intensive treatment (admitted to an intensive care unit (ICU) in the last month of life (OR, 2.33; CI [1.91–2.92], P < 0.001), and received cardiopulmonary resuscitation(OR, 4.18; CI [2.91–5.40],P < 0.001)), than those who did not. Analysis of subgroups showed that the lung cancer was independently associated with targeted therapy, and admission to an ICU was independently associated with palliative chemotherapy.Conclusions: Younger patients without complications and with better performance status were more likely to receive chemotherapy. Lower rates of cardiopulmonary resuscitation and admission to ICU correlated with receipt of targeted therapy at the end of life compared with those who received chemotherapy in the last 30 days.
