RESUMO
The central nervous system (CNS) is one of the most frequent metastatic sites of various cancers, including lung cancer, breast cancer and melanoma. The development of brain metastases requires a specific therapeutic approach and is associated with high mortality and morbidity in cancer patients. Advances in precision medicine and the introduction in recent years of new drugs, such as immunotherapy, have made it possible to improve the prognosis of these patients by improving survival and quality of life. New diagnostic techniques such as liquid biopsy allow real-time monitoring of tumor evolution, providing molecular information on prognostic and predictive biomarkers of response to treatment in blood or other fluids. In this review, we perform an exhaustive update of the clinical trials that demonstrate the utility of immunotherapy in patients with brain metastases and the potential of circulating biomarkers to improving the results of efficacy and toxicity in this subgroup of patients.

Objetivo: Evaluar el grado de satisfacción de los pacientes y/o cuidadores con el tratamiento de citrato de fentanilo transmucosa en la gestión de las crisis de dolor irruptivo oncológico en términos de facilidad de uso. Métodos: Se realizó un estudio observacional, prospectivo y multicéntrico con 48 pacientes sometidos a tratamiento de mantenimiento con opioides para el dolor crónico basal provocado por el cáncer y que, además, sufrían crisis de dolor irruptivo para las que estaban recibiendo tratamiento con citrato de fentanilo. La variable principal del estudio fue el grado de satisfacción de los pacientes y/o sus cuidadores con el citrato de fentanilo en el manejo de las crisis de dolor irruptivo oncológico, evaluadas mediante cuestionarios Escala Visual Analógica (EVA). Resultados: El 90,6 % de los pacientes/cuidadores muestran un elevado grado de satisfacción con el empleo de citrato de fentanilo en términos de facilidad de uso (valor medio EVA de 8,2). Por su parte, tanto la valoración general por parte de los pacientes/cuidadores como por parte de los sanitarios ha sido muy positiva (valor medio EVA 7,7). Conclusiones: El citrato de fentanilo es una terapia fácil de usar y eficaz para el tratamiento de las crisis de dolor irruptivo oncológico, con amplia aceptación tanto por parte de pacientes y cuidadores como de los profesionales sanitarios.(AU)
Objective: To assess the degree of satisfaction of patients and/or caregivers with transmucosal fentanyl citrate treatment in the management of breakthrough cancer pain crises in terms of ease of use. Methods: An observational, prospective and multicenter study was carried out with 48 patients undergoing maintenance treatment with opioids for baseline chronic cancer pain and who, in addition, suffered breakthrough pain crises for those who were receiving treatment with fentanyl citrate. The main variable of the study was the degree of satisfaction of the patients and/or their caregivers with fentanyl citrate in the management of breakthrough cancer pain crises, evaluatedby means of Visual Analogue Scale (VAS) questionnaires. Results: 90.6 % of patients/caregivers show a high degree of satisfaction with the use of fentanyl citrate in terms of ease of use (mean VAS value of 8.2). For its part, both the general assessment by the patients/caregivers and by the healthcare professionals has been very positive (mean VAS value 7.7). Conclusions: Fentanyl citrate is an easy-to-use and effective therapy for the treatment of breakthrough cancer pain crises, widely accepted by both patients and caregivers as well as health professionals.(AU)
