ABSTRACT

There are concerns whether megestrol acetate (MA) stimulates the growth of prostate cancer in castration-resistant prostate cancer (CRPC). We evaluated the effect of cumulative doses of MA on the disease-specific survival (DSS) in patients with CRPC who were receiving Docetaxel-based chemotherapy. From July 2003 through June 2009, we identified 109 consecutive patients with CRPC and who had received docetaxel-based chemotherapy. Of these patients, 68 (62.4%) have not received MA, whereas 21 patients (19.3%) and 20 patients (18.3%) had received low dose MA (total 18,400 mg), respectively. We assessed the effect of several variables on DSS. None of the clinicopathological variables differed among the three groups. When comparing DSS using Kaplan-Meier analysis, there was no statistically significant survival differences among the three groups (P = 0.546). Using multivariate Cox proportional analyses with backward elimination, the number of docetaxel cycles was only significant factor predicting DSS (HR: 0.578, 95% CI: 0.318-0.923, P = 0.016). Cumulative doses of MA as adjuvant treatment for patients with CRPC and who are receiving docetaxel-based chemotherapy, did not affect their DSS. Therefore, MA can be safely administered in cachexic patients with CRPC.

ABSTRACT

Na última década, foram realizados vários estudos sobre alterações gastrointestinais associadas a insuficiência cardíaca crônica. Neste artigo, apresentamos revisão da literatura sobre a fisiopatologia e consequências clínicas das alterações patológicas digestivas de pacientes com insuficiência cardíaca. Anormalidades estruturais e funcionais do trato gastrointestinal, como edema da mucosa absortiva e hipercrescimento bacteriano intestinal, têm sido responsabilizadas por graves consequências clínicas. Entre essas, destacam-se caquexia cardíaca, ativação inflamatória sistêmica e anemia. Essas condições, isoladamente ou em combinação, podem levar a piora da disfunção ventricular preexistente. Embora atualmente não haja terapêutica específica direcionada às alterações gastrointestinais associadas a insuficiência cardíaca, o entendimento das anormalidades digestivas é fundamental para sua prevenção e manejo das consequências sistêmicas.


Over the last decade, several studies were conducted on the gastrointestinal changes associated to chronic heart failure. This article presents a literature review on the physiopathology and clinical consequences of pathological digestive changes of heart failure patients. Structural and functional abnormalities of the gastrointestinal tract, such as edema of absorptive mucosa and intestinal bacterial overgrowth, have been leading to serious clinical consequences. Some of these consequences are cardiac cachexia, systemic inflammatory activation and anemia. These conditions, alone or in combination, may lead to worsening of the pre-existing ventricular dysfunction. Although currently there is no therapy specifically earmarked for gastrointestinal changes associated to heart failure, the understanding of digestive abnormalities is germane for the prevention and management of systemic consequences.

Esas condiciones, aisladamente o de forma combinada, pueden conllevar al empeoramiento de la disfunción ventricular preexistente. Aunque actualmente no exista una terapéutica específica dirigida a las alteraciones gastrointestinales asociadas a la insuficiencia cardíaca, el entendimiento de las anormalidades digestivas es fundamental para su prevención y para el manejo de las consecuencias sistémicas.

ABSTRACT

Se presenta el caso de un paciente del sexo masculino de 2 años de edad, que cursó con retinoblastoma bilateral. El O.D. fue enucleado con persistencia de actividad neoplásica en el borde de sección quirúrgica, lo que propició carcinamatosis meníngea, diseminación al sistema ventricular, invasión al diencéfalo, corteza cerebral y cerebelosa. Se presentan los hallazgos de autopsia y la correlación clínico*patológica
