ABSTRACT

Introduction: Introduction: energy metabolism in cancer patients is influenced by different factors. However, the effect of antineoplastic treatment is not clear, especially in women. Objective: to evaluate resting energy expenditure (REE) by indirect calorimetry (IC) before (T0) and after (T1) first cycle period of antineoplastic therapy: radiotherapy (RT), chemotherapy (CT), and concomitant chemoradiation therapy (CRT), quality of life (QoL) and accuracy of REE were compared with international guidelines recommendations per kilogram (European Society for Clinical Nutrition and Metabolism [ESPEN]). Methods: an observational, longitudinal study was conducted in women with gynecological cancer diagnosis undergoing antineoplastic treatment: RT, CT and CRT. Weight loss, actual body weight and height were measured. REE was evaluated in T0-T1 and compared with ESPEN recommendations. Kruskal-Wallis test and Bland-Alman analysis were used to determine the agreement (± 10 % of energy predicted) of REE adjusted by physical activity (TEE) compared with ESPEN recommendations, respectively. Results: fifty-four women with cancer were included: 31.5 % (n = 17) for RT group, 31.5 % (n = 17) for CT group and 37 % (n = 20) for CRT group. REE showed statistical differences between T0 and T1 in the total population (p = 0.018), but these were not associated with anticancer therapy groups (p > 0.05). QoL had no significant changes after treatment (p > 0.05). Accuracy of 25 and 30 kcal/kg compared to TEE was less than 30 %. Conclusion: REE in women with gynecological cancer decreased after antineoplastic treatments but this is not associated with a particular antineoplastic therapy. It is needed to develop research to determine the accuracy of ESPEN recommendations with TEE estimated by IC and clinical factors in women with cancer.


Introducción: Antecedentes: el metabolismo energético en pacientes con cáncer está influenciado por diferentes factores. Sin embargo, el efecto sobre el tratamiento antineoplásico no es claro, especialmente en mujeres. Objetivo: evaluar el gasto energético en reposo (GER) mediante calorimetría indirecta (CI) antes (T0) y después (T1) del primer ciclo del tratamiento antineoplásico: radioterapia (RT), quimioterapia (QT) y quimio-radioterapia concomitante (QRT), calidad de vida (CdV) y precisión del GER con las con las recomendaciones internacionales por kilogramo de peso (European Society for Clinical Nutrition and Metabolism [ESPEN]). Métodos: se realizó un estudio longitudinal, observacional en mujeres con diagnóstico de cáncer ginecológico en tratamiento antineoplásico. Se evaluó el GER en T0 y T1. Se midieron la pérdida de peso, el peso corporal y la talla. Se usaron las pruebas de Kruskal-Wallis y el análisis Bland-Altman para determinar la concordancia (± 10 % de GER) del REE ajustado por actividad física (TEE) en comparación con las recomendaciones de ESPEN. Resultados: se incluyeron 54 mujeres con cáncer; 31,5 % (n = 17) en el grupo RT, 31,5 % (n = 17) en el de QT y 37 % (n = 20) en el de QRT. GER mostró diferencias estadísticas entre T0 y T1 en la población total (p = 0,018); no se asoció con la terapia contra el cáncer (p > 0,05). La calidad de vida no tuvo cambios significativos después del tratamiento (p > 0,05). La precisión de 25 y 30 kcal/kg en comparación con TEE fue inferior al 30 %. Conclusión: el GER en mujeres con cáncer ginecológico disminuyó después del tratamiento antineoplásico, pero no se asoció a una terapia antineoplásica en particular. Es fundamental desarrollar más investigaciones que compare las recomendaciones de ESPEN y con los valores de la CI comparando más factores clínicos para ofrecer una intervención nutricional precisa.

ABSTRACT

Granulosa cell tumor of the ovary is an uncommon neoplasm characterized by a long natural history, late recurrence capacity and good prognosis. We report the case of a woman with adult-type granulosa cell tumor of the ovary, which developed late recurrence with contralateral ovarian disease, intra-abdominal spread and liver metastases.

ABSTRACT

BACKGROUND: Adjuvant chemotherapy (ACT) reduces recurrence and mortality in breast cancer (BC); however, not all patients require ACT. Oncotype Dx® (ODX) explores the expression of 21 genes and the risk of recurrence BC. OBJECTIVES: To determine the clinicopathologic characteristics, prognosis, and the prescription for ACT in early BC according to ODX risk groups. METHODS: 36 patients with resected stage I-IIA BC, axillary lymph node-negative or 1-3+, hormonal receptor (HR)-positive, HER2 negative. Three groups were designed by ODX: low (LG), medium (MG) and high-risk groups (HG). RESULTS: LG 23 patients (63.9%), MG eight (22.2%) and HG five (13.9%). We detected high expression of Ki-67 in MG and HG in relation to LG, 21.1 and 32.5 versus 10.1%, respectively (p = 0.007) and lower ER-positive, 85.3, 85.4 and 56.9%, respectively (p = 0.005). Recurrence score: LG 12 (0-18), MG 23 (19-27) and HG 47 (36-57); p < 0.000. Pre-ODX, we planned ACT in 21/36 patients (58.3%) and post-ODX only 9/36 patients (25%) received it. No recurrences or deaths were observed in all groups. CONCLUSIONS: In early BC, 64% have low recurrence risk. High-risk cases presented elevated Ki-67 and lower ER expression. ODX modifies the therapeutic recommendation in 57.2% of cases.

ABSTRACT

En su estadio clínico avanzado, el carcinoma urotelial ofrece una expectativa de vida muy baja. Durante los últimos 10 años, la terapia sistémica más utilizada consistió en el esquema MVAC, con índices de respuesta entre 56 y 72 por ciento y respuesta completa de 27 por ciento. El paclitaxel es el agente único que ofrece la mayor actividad en esta neoplasia, 42 por ciento. Para la presente revisión se analizaron los estudios durante el periodo comprendido entre 1990 y 1996, con paclitaxel como fármaco único y en combinación con carboplatino y cisplatino y, los informes sobre la combinación de metotrexato, vinblastina, doxorrubicina y cicplatino (MVAC). Comparativamente, es similar la respuesta que se obtiene con paclitaxel, 53.5 por ciento, y MVAC, 51.7 por ciento. En ambos tratamientos la toxicidad resultó semejante, pero con paclitaxel se observaron grados mayores de leucopenia (74 por ciento) y anemia (18 por ciento). En el caso de pacientes con lesión renal el agente indicado es el texano.
