Intervencionismo para el control del dolor por metástasis óseas / Interventionism for pain control due bone metastases

Objetivo: El dolor óseo por cáncer óseo o metástasis es un dolor de difícil manejo asociado a dolor incidental. Hay distintas estrategias quirúrgicas para su tratamiento, sin embargo, no todos los pacientes con metástasis óseas pueden beneficiarse de un tratamiento quirúrgico. La presente revisión bibliográfica tiene como objetivo identificar terapias intervencionales mínimamente invasivas para el control del dolor por metástasis óseas. Métodos: Revisión bibliográfica acerca de terapias intervencionales para el control del dolor por metástasis óseas utilizando la base de datos PubMed (www.pubmed.gov) y el motor de búsqueda Google (www.google.cl). Tipos de participantes: Pacientes con metástasis óseas dolorosas de cualquier tumor primario. Tipos de intervenciones: Bloqueos anestésicos, bloqueos neurolíticos, terapias ablativas, cementoplastías. Resultados: Se obtuvieron 384 resultados que incluyeron revisiones sistemáticas, revisiones bibliográficas, ensayos clínicos controlados, series de casos y reporte de casos. Todos los artículos relevantes en inglés y español se incluyeron para su análisis. Conclusión: Las metástasis óseas son un evento común en los pacientes con cáncer, y el dolor óseo es un dolor de difícil manejo asociado a dolor incidental. Se han desarrollado terapias intervencionales no invasivas o mínimamente invasivas para tratar el dolor, mejorar la calidad de vida y la funcionalidad, disminuir el consumo de fármacos, y reducir el tamaño del tumor. La gran mayoría ha demostrado ser terapias seguras y eficaces, con pocos eventos adversos y de rápida resolución, y que si son combinadas mejoran los resultados.

Objective: Bone pain from bone cancer or metastasis is a pain that is difficult to manage associated with incidental pain. There are different surgical strategies for its treatment, however, not all patients with bone metastases can benefit from a surgical treatment. This literature review aims to identify minimally invasive interventional therapies for the control of pain due to bone metastasis. Methods: Literature review of interventional therapies for the control of pain due to bone metastases was done using the PubMed database (www.pubmed.gov) and the Google search engine (www.google.cl). Types of participants: Patients with painful bone metastases from any primary tumor. Types of interventions: Anesthetic blocks, neurolytic blocks, ablative therapies, cementoplasties. Results: We obtained 384 results that included systematic reviews, literature reviews, controlled clinical trials, case series and case reports. All relevant articles in English and Spanish were included for analysis. Conclusion: Bone metastases are a common event in cancer patients, and bone pain is a difficult-to-manage pain associated with incidental pain. Non-invasive or minimally invasive interventional therapies have been developed to treat pain, improve quality of life and functionality, decrease drug use, and reduce tumor size. The vast majority therapies have been shown to be safe and effective ones, with few adverse events and rapid resolution, and that if combined they improve the outcomes.

Sobre el concepto de dolor total / On the concept of total pain

RESUMEN El dolor de los pacientes de cáncer ha sido descrito como dolor total. Tanto en la literatura científica, los libros de texto, así como en informes y directrices de la Organización Mundial de la Salud, el concepto de dolor total ha servido de trasfondo para promover la atención multidisciplinaria de pacientes cuyo dolor involucra también aspectos psicológicos, emocionales, espirituales y sociales. El objetivo de este artículo es proponer una caracterización del concepto de dolor total de manera tal que continúe jugando un papel central en la promoción de la atención multidisciplinaria propia de los cuidados paliativos. Primero, se presenta un bosquejo del concepto y de los diferentes usos en la literatura. Segundo, se hace un contraste con la definición del dolor de la Asociación Internacional para el Estudio del Dolor (IASP) para establecer la naturaleza y referente del concepto de dolor total. Tercero, se muestra cómo esta caracterización del concepto disuelve algunas tensiones en la literatura respecto a su uso adecuado. Se plantea que el concepto de dolor total hace referencia a aquellas relaciones causales entre el dolor y los estados psicológicos, emocionales, espirituales y sociales que han sido Identificadas como susceptibles de ser intervenidas por el modelo de atención paliativa multidisciplinar. Como conclusión, se recomienda no vincular el concepto de dolor total con el padecimiento de una enfermedad en particular, ni con qué tan limitante para la vida es la enfermedad; tampoco para referirse a la "experiencia global" del paciente, ni como un punto muy alto de una escala.(AU)

ABSTRACT The pain suffering in cancer patients has been described as "total pain". The concept of "total pain" plays a key role in the promotion of the multidisciplinary nature of palliative care. In palliative attention, suffering is conceptualized as an addition of physical, psychological, emotional, spiritual and social aspects. In this paper, I offer a characterization of the concept of "total pain", one which preserves its key role in palliative care promotion. First, I sketch the concept and some different usages found in the literature. Second, I establish the nature and referent of the "total pain" concept by means of showing the contrast between it and the pain definition provided by the International Association for the Study of Pain (IASP). Third, I propose that the concept of "total pain" refers to the relevant causal chains identified by the palliative care research as elements susceptible of intervention for the purpose of alleviating patient's suffering. These causal chains feature and link physical, psychological, emotional, spiritual and social aspects of the patient's suffering. As conclusion, I add the recommendation to not associate the concept of "total pain" with any particular diagnostic or disease or any particular prognosis, neither to the global experience of the patient, nor treat it as a high point on a scale.(AU)

Mesencephalotomy, How I Do It: Analysis of 34 Cases

The present paper aims to demystify the use of rostral mesencephalic reticulotomy (mesencephalotomy) in the treatment of chronic pain in cancer patients. A retrospective review of the medical records from the Central Pain and Stereotaxy Department of the A. C. Camargo Cancer Center, São Paulo, state of São Paulo, Brazil, between 2005 and 2012, was performed. Surgical indication was restricted to patients with cancer pain refractory to etiological and symptomatic treatments, > 2 months of expected survival, preserved cognition, and absence of coagulation disorders, of systemic infection, and of intracranial hypertension. We have selected 34 patients, with an average follow-up of 9.4 months, an average age of 54.3 years-old, and an average follow-up time until death of 6.4 months. Lung cancer was themost frequent diagnosis. Satisfactory and immediate pain relief was achieved in 91% of the cases, and 83% of these patients had no relapses. Among the complications, ocular movement disorder was the most frequent, but often transient. Permanent disturbances occurred in 8.8% of the cases (diplopia, rubral tremor, and paresthesia). Compared to the pharmacological treatment, mesencephalotomy was economically feasible, more effective, and improved quality of life. According to the data presented, it can be concluded that mesencephalotomy is a viable procedure for cancer pain control in selected cases.

Single needle versus double needle celiac trunk neurolysis in abdominal malignancy pain management: a randomized controlled trial / Neurólise do tronco celíaco com o uso de agulha única versus agulha dupla no manejo da dor abdominal maligna: estudo randômico controlado

Abstract Background: Computerized tomography-guided celiac plexus neurolysis has become almost a safe technique to alleviate abdominal malignancy pain. We compared the single needle technique with changing patients' position and the double needle technique using posterior anterocrural approach. Methods: In Double Needles Celiac Neurolysis Group (n = 17), we used two needles posterior anterocrural technique injecting 12.5 mL phenol 10% on each side in prone position. In Single Needle Celiac Neurolysis Group (n = 17), we used single needle posterior anterocrural approach. 25 mL of phenol 10% was injected from left side while patients were in left lateral position then turned to right side. The monitoring parameters were failure block rate and duration of patient positioning, technique time, Visual Analog Scale, complications (hypotension, diarrhea, vomiting, hemorrhage, neurological damage and infection) and rescue analgesia. Results: The failure block rate and duration of patient positioning significantly increased in double needles celiac neurolysis vs. single needle celiac neurolysis (30.8% vs. 0%; 13.8 ± 1.2 vs. 8.9 ± 1; p = 0.046, p ≤ 0.001 respectively). Also, the technique time increased significantly in double needles celiac neurolysis than single needle celiac neurolysis (24.5 ± 5.1 vs. 15.4 ± 1.8; p ≤ 0.001). No significant differences existed as regards Visual Analog Scale: double needles celiac neurolysis = 2 (0-5), 2 (0-4), 3 (0-6), 3 (2-6) and single needle celiac neurolysis = 3 (0-5), 2 (0-5), 2 (0-4), 4 (2-6) after 1 day, 1 week, 1 and 3 months respectively. However, Visual Analog Scale in each group reduced significantly compared with basal values (p ≤ 0.001). There were no statistically significant differences as regards rescue analgesia and complications (p > 0.05). Conclusion: Single needle celiac neurolysis with changing patients' position has less failure block rate, less procedure time, shorter duration of patient positioning than double needles celiac neurolysis in abdominal malignancy.

Resumo Introdução: A neurólise do plexo celíaco guiada por tomografia computadorizada tornou-se uma técnica quase segura para aliviar a dor abdominal maligna. Comparamos a técnica de agulha única mudando o posicionamento do paciente e a técnica de agulha dupla usando a abordagem anterocrural posterior. Métodos: No grupo designado para neurólise celíaca com agulha dupla (n = 17), a técnica de abordagem anterocrural posterior foi utilizada com duas agulhas para injetar 12,5 mL de fenol a 10% de cada lado em decúbito ventral. No grupo designado para neurólise celíaca com agulha única (n = 17), a abordagem anterocrural posterior foi utilizada com uma única agulha para injetar 25 mL de fenol a 10% do lado esquerdo com o paciente em decúbito lateral esquerdo e posteriormente virado para o lado direito. Os parâmetros de monitorização foram a taxa de falha dos bloqueios e a duração do posicionamento dos pacientes, o tempo da técnica, os escores da escala visual analógica, as complicações (hipotensão, diarreia, vômitos, hemorragia, dano neurológico e infecção) e a analgesia de resgate. Resultados: A taxa de falha dos bloqueios e a duração do posicionamento dos pacientes aumentaram significativamente na neurólise celíaca com o uso de agulha dupla vs. agulha única (30,8% vs. 0%,13,8 ± 1,2 vs. 8,9 ± 1; p = 0,046, p ≤ 0,001, respectivamente). Além disso, o tempo da técnica foi significativamente maior na neurólise celíaca com agulha dupla que na neurólise celíaca com agulha única (24,5 ± 5,1 vs. 15,4 ± 1,8; p ≤ 0,001). Não houve diferença significativa em relação aos escores da escala visual analógica: neurólise celíaca com agulha dupla = 2 (0-5), 2 (0-4), 3 (0-6), 3 (2-6) e neurolise celíaca com agulha única = 3 (0-5), 2 (0-5), 2 (0-4), 4 (2-6) após um dia,uma semana, um e três meses, respectivamente. No entanto, os escores da escala visual analógica para cada grupo foram significativamente menores comparados aos valores basais (p ≤ 0,001). Não houve diferença estatisticamente significativa quanto à analgesia de resgate e complicações (p > 0,05). Conclusão: A neurólise celíaca com o uso de agulha única e a alteração do posicionamento do paciente apresenta uma taxa menor de falha do bloqueio, menos tempo de procedimento e menor duração do posicionamento do paciente que o uso de duas agulhas para neurólise celíaca em malignidade abdominal.

Avaliação e tratamento da dor em oncologia pediatrica / Pain assessment and treatment in children with oncological diseases

Nos últimos anos ocorreu considerável melhora na sobrevida das crianças com câncer. Nos últimos anos ocorreu considerável melhora na sobrevida das crianças com câncer. Entretanto, apesar da crescente conscientização sobre as causas e tratamento da dor, estudos mostram que essas crianças continuam a experimentar diariamente sintomas angustiantes, físicos e emocionais causados pela doença e seu tratamento. O objetivo deste trabalho foi revisar a literatura a respeito das particularidades associadas à dor infantil relacionada ao câncer, salientando as suas principais causas assim como as possibilidades terapêuticas disponíveis. Foram revisados artigos referentes ao tema proposto, publicados nos últimos 20 anos, entre janeiro de 1990 e novembro de 2010, utilizando as bases Scientific Eletronic Library Online (SCIELO) e National Library Of Medicine ­ PubMed (MEDLINE). A chave para o controle da dor é a obtenção de uma avaliação detalhada por equipe multidisciplinar para o desenvolvimento de um plano de tratamento específico para cada criança, com frequentes reavaliações. Apesar de algumas limitações, a escada analgésica da Organização Mundial de Saúde serve como pilar para o tratamento desses pacientes, contribuindo para o alívio da dor oncológica em todo o mundo. Para melhor abordagem, terapias combinadas (farmacológicas e não farmacológicas) devem ser utilizadas adaptando-se às necessidades individuais, com o objetivo de minimizar a dor e os efeitos adversos do tratamento. (AU)

In recent years there has been a considerable improvement in survival of children with cancer. However, despite growing awareness about the causes and treatment of pain, studies show that these children continue to experience daily physical and emotional distressing symptoms caused by the disease and its treatment. The aim of this study was to review the literature regarding the particularities associated with children pain related to cancer, highlighting their main causes and therapeutic possibilities available. We reviewed articles relating to the proposed theme published from the last 20 years, between January 1990 and November 2010 using the bases Scientific Electronic Library Online (SciELO), National Library Of Medicine ­ PubMed (MEDLINE). The key to pain control is to obtain a detailed evaluation by a multidisciplinary team to develop a specific treatment plan for each child, with frequent reassessments. Despite some limitations, the analgesic ladder of the World Health Organization serves as a pillar to treat these patients, providing pain relief worldwide. For a better pain management, combined therapies (pharmacological and nonpharmacological) should be used adapted to individual needs, in order to minimize pain and side effects of treatment.(AU)
