ObjectiveThe aim of this study was to analyze the prognostic factors correlated with survival of patients with acute myeloid leukemia at the Hospital de Clínicas, Universidade Federal do Paraná between 2003 and 2009, as well as to investigate the clinical and epidemiological profile.MethodsThe overall survival and disease-free survival were statistically evaluated using the Kaplan–Meier method, the log-rank test and multivariate evaluation by Cox regression analysis.ResultsThe study population was predominantly younger than 60 years old (81,6%), had intermediate cytogenetic risk (40.8%), in first complete remission after induction chemotherapy (46.9%), with a white blood count at diagnosis of less than 30 × 109/L (57.1%) and de novo acute myeloid leukemia (62.2%). Survival curves showed that better prognosis was related to age below 60 years (median:12,4 months; p-value = 0,2227; Odds Ratio = 0,6676), good prognostic cytogenetic markers (median: 97.7 months; p-value = 0.0037; Odds Ratio = 0.4239) and white blood cell count at diagnosis of less than 30 × 109/L (median survival: 23.6 months; p-value = 0.0001; Odds Ratio = 0.3651). Regarding the French-American-British subgroups, the median overall survival was 23.5 months for M0, M1 and M2, 97.7 months for M3 and 7.4 months for M4, M5, M6, and M7 (p-value = 0.0288).ConclusionPrognostic factors strongly influenced patient survival, as well as guided treatment. Moreover, these factors were consistent with the available literature adjusted for the population in question.

Background Cancer patients with acute venous thromboembolism (VTE) receiving anticoagulant treatment have an increased bleeding risk. Objectives We performed a prespecified secondary analysis of the randomized, open-label, Phase III CATCH trial (NCT01130025) to assess the rate and sites of and the risk factors for clinically relevant bleeding (CRB). Patients/Methods Patients with active cancer and acute, symptomatic VTE received either tinzaparin 175 IU kg once daily or warfarin (target International Normalized Ratio [INR] of 2.0-3.0) for 6 months. Fisher's exact test was used to screen prespecified clinical risk factors; those identified as being significantly associated with an increased risk of CRB then underwent competing risk regression analysis of time to first CRB. Results Among 900 randomized patients, 138 (15.3%) had 180 CRB events. CRB occurred in 60 patients (81 events) in the tinzaparin group and in 78 patients (99 events) in the warfarin group (hazard ratio [HR] 0.64; 95% confidence interval [CI] 0.45-0.89). Common bleeding sites were gastrointestinal (36.7%; n = 66), genitourinary (22.8%; n = 41), and nasal (10.0%; n = 18). In multivariate analysis, the risk of CRB increased with age > 75 years (HR 1.83, 95% CI 1.14-2.94) and intracranial malignancy (HR 1.97, 95% CI 1.07-3.62). In the warfarin group, 40.4% of CRB events occurred in patients with with an INR of < 3.0. A lower time in therapeutic range was associated with a higher risk of CRB. Conclusions CRB is a frequent complication in cancer patients with VTE during anticoagulant treatment, and is associated with age > 75 years and intracranial malignancy.

1084 Background: Gemcitabine plus cisplatin have synergistic activity and have been tested in several schedules and doses in metastatic breast cancer. Our objectives were to assesss the efficacy and toxicity of gemcitabine and cisplatin in pretreated patients. Methods: Measurable disease and at least two prior anthracycline and /or taxane-containing regimen in either metastatic or adjuvant setting was required. Treatment consisted of gemcitabine 700mg/m(2) IV infusion over 30 min plus cisplatin 30mg(2) given on day1 and 8 every 3 weeks. Results: Seventy four patients with median age of 48 years (range 26- 73) were recruited. A median of six cycles of the study treatment was delivered. The overal response rate was 30% (95% confidence interval, 12–53%). Median time to progreesion was 30.6 weeks (95%CI, 12.6–44 weeks). Median survival was 73.2 weeks (95% CI, 47.1–93.2 weeks). Toxicities included grade 3 and 4 leukopenia in 27(36.4%), anemia in 19 (25.6%) and oral mucositis in 4 (5.4%). No grade 3 or 4 peripheral neurophaty, hepatic or renal dysfunction was observed. No treatment-related death ocurred. Conclusions: Gemcitabine plus cisplatin is a well tollerated and active treatment in heavily pretreated patients with metastatic breast cancer.

Introdução: A adesão aos antineoplásicos orais (AO) e um importante indicador de resposta terapêutica relacionada a fatores pessoais, sociais e estruturais. Objetivo: Determinar as taxas de adesão aos AO, investigando possíveis fatores de risco para a não adesão, e avaliar as crenças dos pacientes sobre medicamentos, identificando oportunidades de intervenção farmacêutica. Método: Estudo analítico realizado com pacientes com câncer em uso de AO em 2015. Escala de Adesão e Recarga dos Medicamentos (ARMS) e Questionário de Crenças sobre Medicamentos (BMQ) foram aplicados para avaliar a adesão e crenças sobre medicamentos e tratamento. Os testes de Mann-Whitney, qui-quadrado e exato de Fisher foram usados para análise de dados. Resultados: Foram entrevistados 222 pacientes, com taxa de adesão de 92,8%, segundo o ARMS e 84,7%, segundo o BMQ, no qual as crenças de necessidade excederam as preocupações com o tratamento e o uso de AO. Renda familiar, interrupção do tratamento, número e causas das interrupções, depressão e razão de posse de medicamentos foram os fatores de risco identificados. A comparação dos domínios do BMQ demostrou que, no grupo aderente, as crenças dos pacientes sobre a necessidade do medicamento excederam suas preocupações quanto a isso. Conclusão: Considerar as crenças do paciente e um fator decisivo para compreender os riscos relacionados a não adesão, bem como para definir estratégias para lidar com ela.
