- Associação da Intensidade de Dor no Tempo Até à Morte dos Doentes Oncológicos Referenciados aos Cuidados PaliativosPublication . Barata, P; Santos, F; Mesquita, G; Cardoso, A; Custódio, MP; Alves, M; Papoila, AL; Barbosa, A; Lawlor, PIntrodução: A dor é uma experiência frequente nos doentes com cancro, especialmente naqueles em fase final de vida. Com este estudo, pretendemos estudar a intensidade de dor nos doentes com cancro avançado, referenciados aos cuidados paliativos, analisar os factores associados à ocorrência de dor moderada ou intensa e avaliar a sua relação com o tempo até à morte destes doentes. Material e Métodos: Estudo prospectivo observacional que incluiu consecutivamente todos os doentes referenciados aos cuidados paliativos com tumores sólidos metastizados e sem tratamento oncológico específico. Foi considerada a intensidade de dor da escala de Edmonton, de acordo com a graduação zero a 10, onde 0 = ausência de dor e 10 = máxima dor possível. Resultados: Entre outubro de 2012 e junho de 2015, foram incluídos 301 doentes, com idade mediana de 69 anos (37 - 94), 57% homens e 64,8% dos doentes com performance status 3/4. Aproximadamente 42% dos doentes apresentaram dor ≥ 4 e cerca de 74,4% estavam medicados com analgesia opióide. A intensidade de dor esteve associada ao performance status dos doentes, de acordo com a análise multivariável (OR: 1,7; IC 95%: 1,0 - 2,7; p = 0,045). A mediana do tempo de sobrevivência foi de 37 dias (IC 95%: 28 - 46), tendo os doentes com dor moderada ou intensa (intensidade de dor ≥ 4) uma mediana de sobrevivência de 29 dias (IC 95%: 21 - 37), comparada com os 49 dias (IC 95%: 35 - 63) para os doentes sem dor ou dor ligeira (p = 0,022). Discussão: O performance status, para além de ter estado associado a uma maior intensidade de dor, esteve associado a um menor tempo até à morte dos doentes com cancro avançado referenciados aos cuidados paliativos. Também o internamento, a presença de metastização intra-abdominal e a analgesia opióide estiveram associados de forma negativa ao tempo até à morte destes doentes. Conclusão: A dor oncológica continua a ser um problema clinicamente relevante nos doentes com cancro avançado.
- Symptom Clusters and Survival in Portuguese Patients with Advanced CancerPublication . Barata, P; Cardoso, A; Custodio, M; Alves, M; Papoila, AL; Barbosa, A; Lawlor, PThis study aimed to identify clusters of symptoms, to determine the patient characteristics associated with identified, and determine their strength of association with survival in patients with advanced cancer (ACPs). Consecutively eligible ACPs not receiving cancer-specific treatment, and referred to a Tertiary Palliative Care Clinic, were enrolled in a prospective cohort study. At first consultation, patients rated 9 symptoms through the Edmonton Symptom Assessment System (0-10 scale) and 10 others using a Likert scale (1-5). Principal component analysis was used in an exploratory factor analysis to identify. Of 318 ACPs, 301 met eligibility criteria with a median (range) age of 69 (37-94) years. Three SCs were identified: neuro-psycho-metabolic (NPM) (tiredness, lack of appetite, lack of well-being, dyspnea, depression, and anxiety); gastrointestinal (nausea, vomiting, constipation, hiccups, and dry mouth) and sleep impairment (insomnia and sleep disturbance). Exploratory factor analysis accounted for 40% of variance of observed variables in all SCs. Shorter survival was observed for patients with the NPM cluster (58 vs. 23, P < 0.001), as well as for patients with two or more SCs (45 vs. 21, P = 0.005). In a multivariable model for survival at 30-days, age (HR: 0.98; 95% CI: 0.97-0.99; P = 0.008), hospitalization at inclusion (HR: 2.27; 95% CI: 1.47-3.51; P < 0.001), poorer performance status (HR: 1.90, 95% CI: 1.24-2.89; P = 0.003), and NPM (HR: 1.64; 95% CI: 1.17-2.31; P = 0.005), were associated with worse survival. Three clinically meaningful SC in patients with advanced cancer were identifiable. The NPM cluster and the presence of two or more SCs, had prognostic value in relation to survival.
- Symptom Clusters in Patients With Advanced Cancer: a Prospective Longitudinal Cohort Study to Examine Their Stability and Prognostic SignificancePublication . Simão, D; Barata, P; Alves, M; Papoila, AL; Oliveira, S; Lawlor, PThis study's purpose was to assess symptom cluster (SC) stability during disease progression and determine their strength of association with survival in patients with advanced cancer . Consecutively eligible patients with advanced cancer not receiving cancer-specific treatment and referred to a Tertiary Palliative Care Clinic were enrolled in a prospective cohort study. At first consultation (D0) and in subsequent consultations at day 15 (D15) and day 30 (D30), patients rated 9 symptoms through the Edmonton Symptom Assessment System scale (0-10) and 10 others using a Likert scale (1-5). Principal components factor analysis with varimax rotation was used to determine SCs at each consultation. Of 318 patients with advanced cancer, 301 met eligibility criteria with a median age of 69 years (range 37-94). Three SCs were identified: neuro-psycho-metabolic (NPM), gastrointestinal, and sleep impairment, with some variations in their constitution over time. Exploratory factor analysis accounted for 40% of variance of observed variables in all SCs. Shorter median survival was observed continuously for NPM cluster (D0 23 vs. 58 days, P < .001; D15 41 vs. 104 days, P=.004; D30 46 vs. 114 days, P = .002), although the presence of 2 or more SCs on D0 and D15 also had prognostic significance (D0: 21 vs. 45 days, P = .005; D30: 50 vs. 96 days, P = .040). In a multivariable model, NPM cluster (D0 hazard ratio estimate: HR 1.64; 95%CI, 1.17-2.31; P = .005; D15 HR: 2.51; 95%CI, 1.25-5.05; P = .009; D30 HR: 3.9; 95%CI, 1.54-9.86; P = .004) and hospitalization (D0 HR: 2.27; 95%CI, 1.47-3.51; P < .001; D15 HR: 2.43; 95%CI, 1.18-5.01; P = .016; D30 HR: 3.41; 95%CI, 1.35-8.62; P = .009) were independently and significantly associated with worse survival. Three clinically relevant SCs were identified, and their constitution had small variations, maintaining a stable set of nuclear symptoms through disease progression. Presence of the NPM cluster and hospitalization maintained their prognostic value over time.
