          Abstract

          Abstract Introduction: current data regarding the decision on rehydration of patients with terminal-stage cancer remain controversial. Objective: the present study was to evaluate the effect of intravenous hydration and supplementary vitamins and trace elements on clinical symptoms and biochemical parameters in palliative cancer patients. Methods: a randomized clinical trial including 72 palliative cancer patients aged 18 years and older was performed at the National Cancer Institute in Mexico. Patients were divided into two groups: intervention and control, both receiving intravenous saline solution weekly for 4 weeks, but the former was also supplemented with vitamins and trace elements. Symptoms were assessed at baseline and 4 weeks after with the Edmonton Symptom Assessment Scale. Same measurements applied to biochemical parameters. Results: the mean age of the patients was 58.75 years. The most frequent cancer diagnoses were gastrointestinal (32 %). In the between-groups analysis significant improvements were found for the intervention group in anorexia (p = 0.024), pain (p = 0.030), chloride (p = 0.043), phosphorus (p = 0.001), potassium (p = 0.006), and total proteins (< 0.0001). Conclusion: we highlight the improvement in the control of most symptoms and some biochemical parameters in the intervention group receiving vitamins and oligoelements along with intravenous hydration. Further studies are needed.

          Resumen Introducción: los datos actuales sobre la decisión de rehidratación de pacientes con cáncer en fase terminal siguen siendo controvertidos. Objetivo: el presente estudio fue evaluar el efecto de la hidratación intravenosa y la suplementación con vitaminas y oligoelementos sobre los síntomas clínicos y parámetros bioquímicos en pacientes con cáncer paliativo. Métodos: en el Instituto Nacional del Cáncer de México se realizó un ensayo clínico aleatorizado que incluyó a 72 pacientes con cáncer paliativo de 18 años o más. Los pacientes se dividieron en dos grupos: intervención y control, ambos recibieron solución salina intravenosa semanalmente durante 4 semanas, pero el primero también se complementó con vitaminas y oligoelementos. Los síntomas se evaluaron al inicio del estudio y 4 semanas después con la escala de evaluación de síntomas de Edmonton. Mismas medidas aplicadas a los parámetros bioquímicos. Resultados: la edad media de los pacientes fue de 58,75 años. El diagnóstico de cáncer más frecuente fue el gastrointestinal (32 %). En el análisis entre grupos se encontraron mejoras significativas para el grupo de intervención en anorexia (p = 0,024), dolor (p = 0,030), cloro (p = 0,043), fósforo (p = 0,001), potasio (p = 0,006) y proteínas totales (< 0,0001). Conclusión: destacamos la mejoría en el control de la mayoría de los síntomas y algunos parámetros bioquímicos en el grupo de intervención que recibió vitaminas y oligoelementos junto con hidratación endovenosa. Se necesitan más estudios.

          Symptom prevalence in patients with incurable cancer: a systematic review.

          The suffering of patients with incurable cancer is determined to a large degree by the presence and intensity of the symptoms of their disease. Knowledge of symptom prevalence is important for clinical practice. The main aim of this study was to obtain a reliable estimation of symptom prevalence in patients with incurable cancer by performing a systematic review of studies assessing this topic. We included 44 studies (including 25,074 patients) on overall symptom prevalence (Group 1) and six studies (including 2,219 patients) on symptom prevalence during the last one to two weeks of life (Group 2). In these studies, symptom prevalence was assessed by a questionnaire, a standardized interview, or the medical record. We identified 37 symptoms assessed in at least five studies. Almost all symptoms occurred in more than 10% of the patients. Five symptoms (fatigue, pain, lack of energy, weakness, and appetite loss) occurred in more than 50% of the patients of Group 1. Weight loss occurred significantly more often in Group 2 compared to Group 1, and pain, nausea, and urinary symptoms occurred significantly less often. Generally, symptom prevalence was highest if assessed by a questionnaire. The results of this study should be used to guide doctors and nurses in symptom management. Proper attention to symptom burden and suffering should be the basis for individually tailored treatment aimed at improving or maintaining quality of life of patients in their last period of life.

            High prevalence of pain in patients with cancer in a large population-based study in The Netherlands.

            At present, no definite conclusions can be drawn about the real extent of the pain suffered by cancer patients. A population-based study was conducted to obtain reliable information about the prevalence and severity of pain in cancer patients (all phases) and about predictors of pain. A representative sample of cancer patients was recruited in the area from a cancer registry. Pain was assessed by the Brief Pain Inventory (BPI). Adequacy of pain treatment was assessed with the Pain Management Index (PMI). We found that 55% of the 1429 respondents had experienced pain past week; in 44% (n=351), the pain was moderate to severe (BPI score>or= 4). Total prevalence of pain/moderate to severe pain was present in 49%/41% in patients with curative treatment >or=6 months ago, 57%/43% in patients with current curative treatment or treatment <6 months ago, 56%/43% in patients with current palliative anti-cancer treatment and in 75%/70% in patients for whom treatment was no longer feasible. Positive predictors of the prevalence of pain were lower education level, more advanced disease and haematological (excluding (non)-Hodgkin lymphoma), gastro-intestinal, lung, or breast malignancies. According to the PMI, analgesic treatment was inadequate in 42% of the patients. Negative predictors of adequate treatment were current curative anti-cancer treatment and low education level. A substantial proportion of cancer patients does suffer from moderate to severe pain and does not receive adequate pain treatment.

              Parenteral hydration in patients with advanced cancer: a multicenter, double-blind, placebo-controlled randomized trial.

              The vast majority of patients with cancer at the end of life receive parenteral hydration in hospitals and no hydration in hospice, with limited evidence supporting either practice. In this randomized controlled trial, we determined the effect of hydration on symptoms associated with dehydration, quality of life, and survival in patients with advanced cancer.
