Prognostic assessment in palliative cancer care: is there a difference between adult and older patients?

OBJECTIVE: To compare factors associated with death in adults and older people with advanced cancer who were hospitalized in a palliative care unit (PCU). METHODS: Case-control study with patients (adults vs older people) admitted to a PCU of National Cancer Institute José Alencar Gomes da Silva (INCA), in Rio de Janeiro, Brazil. Logistic regressions (odds ratio [OR] and 95% confidence interval [95%CI]) were used to identify factors associated with death. RESULTS: The study included 205 patients, most of which were aged over 60 years old (60.5%). Among the adult patients, a Karnofsky Performance Status ≤ 40% (OR 2.54 [95%CI 1.11–3.45]) and neutrophil-to-lymphocyte ratio (NLR) (OR 1.09 [95%CI 1.02–1.24]) were risk factors for death, while albumin (OR 0.30 [95%CI 0.12–0.78]) was a protective factor. Among older patients, NLR (OR: 1.13 [95%CI 1.02–1.24]), C-reactive protein (CRP) (OR 1.09 [95%CI 1.02–1.17]), modified Glasgow Prognostic Score (mGPS) 1 and 2 (OR 4.66 [95%CI 1.35–16.06]), CRP-to-albumin ratio (CAR) (OR 1.27 [95%CI 1.03–1.58]), and nutritional risk (OR 1.11 [95%CI 1.03–1.19]) were risk factors, whereas albumin (OR 0.23 [95%CI 0.09–0.57]) was a protective factor against death. CONCLUSIONS: Prognostic factors differed between groups. The NLR was a risk factor, and albumin was a protective factor regarding death in both groups. Additionally, CRP, mGPS, CAR, and nutritional risk were associated with an increased risk of death only among older people.
