Background: The most important decision after diagnosing terminal cancer is whether to provide active therapy or withhold treatment. Objective: To analyze the aggressiveness of care by evaluating systemic anticancer therapy (SACT) given near to death, describing this care and identifying factors that determine its use. Design: This involves retrospective observational cohorts study. Setting/Subjects: This involves patients with metastatic tumors who died at a University Hospital in Spain between 2015 and 2016. Measurements: Data obtained from prescribing oncologists and patients' clinical records, type of cancer, and information on treatment. The dependent variable used was the interval between the date of the last dose and date of death. Results: Ninety-four (32.60%) of 288 patients received SACT in the last month of life. This cohort had a higher frequency of lung cancer (OR: 1.58; CI 95%: 1.14-2.18), received more care from oncologist 2 (OR: 1.50; CI 95%: 1.08-2.08), had fewer last-line treatment cycles (OR: 1.28; CI 95%: 1.13-1.45), a lower subjective response (OR: 3.13; CI 95%: 1.34-7.29), less clinical benefit (OR: 2.38; CI 95%: 1.04-5.55), more visits to the Emergency Department (OR: 1.59; CI 95%: 1.06-2.38), and less care from the Palliative Care Unit (OR: 4.55; CI 95%: 2.69-7.70). In multivariate analysis, the predictors of having received SACT close to death remained: receiving fewer cycles of treatment (OR: 1.28; CI 95%: 1.12-1.47) and less palliative care (OR: 4.54; CI 95%: 2.56-7.69). Conclusions: A third of cancer patients received SACT in the last month of life with less efficacy and poorer quality of care than patients not receiving it.
