Consensus statement of the Spanish Society of Neurology on the treatment of multiple sclerosis and holistic patient management in 2023.

The last consensus statement of the Spanish Society of Neurology's Demyelinating Diseases Study Group on the treatment of multiple sclerosis (MS) was issued in 2016. Although many of the positions taken remain valid, there have been significant changes in the management and treatment of MS, both due to the approval of new drugs with different action mechanisms and due to the evolution of previously fixed concepts. This has enabled new approaches to specific situations such as pregnancy and vaccination, and the inclusion of new variables in clinical decision-making, such as the early use of high-efficacy disease-modifying therapies (DMT), consideration of the patient's perspective, and the use of such novel technologies as remote monitoring. In the light of these changes, this updated consensus statement, developed according to the Delphi method, seeks to reflect the new paradigm in the management of patients with MS, based on the available scientific evidence and the clinical expertise of the participants. The most significant recommendations are that immunomodulatory DMT be started in patients with radiologically isolated syndrome with persistent radiological activity, that patient perspectives be considered, and that the term "lines of therapy" no longer be used in the classification of DMTs (> 90% consensus). Following diagnosis of MS, the first DMT should be selected according to the presence/absence of factors of poor prognosis (whether epidemiological, clinical, radiological, or biomarkers) for the occurrence of new relapses or progression of disability; high-efficacy DMTs may be considered from disease onset.

[Periodic plasmapheresis as maintenance treatment in relapsing-remitting multiple sclerosis, a new therapeutic line? A case report]. / Plasmaféresis periódica como tratamiento de mantenimiento en la esclerosis múltiple remitente-recurrente, ¿nueva línea terapéutica? A propósito de un caso.

INTRODUCTION: Relapsing-remitting multiple sclerosis (RRMS) treatment has significantly changed in recent years because of the discovery of new molecules that have shown efficacy as maintenance treatment. However, the classical treatment for acute attacks is based on corticosteroids administration, being the periodical plasmapheresis the alternative treatment in the case of refractory patients. We introduce a case of relapsing-remitting multiple sclerosis treated with a classical acute attacks therapy: plasmapheresis. CASE REPORT: The case of a 39-year-old patient who was diagnosed with relapsing-remitting multiple sclerosis, postpartum debut and aggresive course, who, after suboptimal response to disease modifying therapies (alemtuzumab and ocrelizumab), receives combination treatment with outpatient periodic plasmapheresis every 3 weeks as maintenance therapy. Good tolerance and response. Clinical stability with this treatment. She has not required new hospital admissions for acute attacks of multiple sclerosis from February 2020 to March 2021. CONCLUSION: Although more specific studies are needed, this case provides information on a potential new maintenance treatment for patients with relapsing-remitting multiple sclerosis refractory to disease-modifying drug therapies.

TITLE: Plasmaféresis periódica como tratamiento de mantenimiento en la esclerosis múltiple remitente-recurrente, ¿nueva línea terapéutica? A propósito de un caso.Introducción. El tratamiento de la esclerosis múltiple remitente-recurrente ha evolucionado significativamente en los últimos años con el descubrimiento de nuevas moléculas eficaces como tratamiento de mantenimiento. Por otro lado, el tratamiento de los brotes de esta enfermedad se basa clásicamente en corticoides, y en los casos refractarios a esta terapia se utiliza plasmaféresis. Presentamos un caso de esclerosis múltiple remitente-recurrente tratada periódicamente con una terapia que se ha utilizado clásicamente para los brotes: plasmaféresis. Caso clínico. Mujer de 39 años con esclerosis múltiple remitente-recurrente de inicio en el posparto, gran carga lesional y curso agresivo, en quien, ante una respuesta subóptima a terapias modificadoras de la enfermedad (alemtuzumab y ocrelizumab), se decide iniciar un tratamiento combinado junto con plasmaféresis periódicas ambulatorias cada tres semanas como tratamiento de mantenimiento. Se constata una buena tolerancia a esta terapia y evolución, y se produce estabilidad clínica. No ha requerido nuevos ingresos hospitalarios por brotes desde febrero de 2020 a marzo de 2021. Conclusión. Aunque es necesario que se realicen más estudios, este caso ofrece información sobre un potencial tratamiento de mantenimiento para pacientes con esclerosis múltiple remitente-recurrente refractaria a terapias con fármacos modificadores de la enfermedad.

INTRODUCTION: For more than a decade, after the ECTRIMS Congress, Spain has hosted the Post-ECTRIMS meeting, where neurologists with expertise in multiple sclerosis (MS) meet to review the new developments presented at the ECTRIMS. AIM: This article, published in two parts, summarises the presentations of the post-ECTRIMS meeting, held online on 16 and 17 October 2020. DEVELOPMENT: This second part highlights the importance of gender and age in understanding the pathology of the disease and optimising its management. The advances made in paediatric MS, from a neuropsychological and neuroimaging point of view, are presented. In turn, special attention is paid to the findings that contribute to a more personalised approach to therapy and to choosing the best treatment strategy (pharmacological and non-pharmacological) for each patient. Similarly, results related to possible strategies to promote remyelination are addressed. Although there are no major advances in the treatment of progressive forms, some quantitative methods for the classification of these patients are highlighted. In addition, the study also includes results on potential tools for assessment and treatment of cognitive deficits, and some relevant aspects observed in the spectrum of neuromyelitis optica disorders. Finally, the results of the papers considered as breaking news at the ECTRIMS-ACTRIMS are detailed. CONCLUSIONS: Most of the advances presented were related to the knowledge of paediatric MS, remyelination strategies and cognitive assessment in MS.

12th Post-ECTRIMS Meeting: review of the novelties from the 2019 ECTRIMS Congress (II). / XII Reunión Post-ECTRIMS: revisión de las novedades presentadas en el Congreso ECTRIMS 2019 (II).

INTRODUCTION: Like every year, after the ECTRIMS Congress, renowned Spanish neurologists who are experts in multiple sclerosis presented the main novelties in research in this field at the Post-ECTRIMS Meeting. AIM: To summarise the content presented at the 12th edition of the Post-ECTRIMS Meeting, which took place in September 2019 in Sevilla and is presented in two parts. DEVELOPMENT: In this second part, the most recent evidence on the use of disease-modifying treatments during pregnancy is presented. Details are provided concerning the results of phase 3 clinical trials conducted to evaluate the efficacy and safety of two potential disease-modifying treatments for relapsing-remitting multiple sclerosis: ponesimod and ofatumumab. For the progressive forms, both available disease modifying treatments and others still in the research phase are reviewed. In the field of stem cell therapies, the article includes the results of the only clinical trial carried out to date comparing patients with relapsing-remitting multiple sclerosis treated with autologous haematopoietic stem cell transplantation and those treated with disease-modifying therapies. There are no important developments as regards symptomatic treatments, although the European Academy of Neurology has published a guide on palliative care. The various sources of information that collect pharmacovigilance data in the post-marketing setting are reviewed. CONCLUSIONS: Patients diagnosed in recent years tend to have less severe multiple sclerosis, probably due to the fact that it is diagnosed in its milder stages together with the steady increase in the number of treatments available.

INTRODUCTION: Like every year, after the ECTRIMS Congress, renowned Spanish neurologists who are experts in multiple sclerosis presented the main novelties in research in this field at the Post-ECTRIMS Meeting. AIM: To summarise the content presented at the 12th edition of the Post-ECTRIMS Meeting, which took place in September 2019 in Sevilla and is presented in two parts. DEVELOPMENT: This first part addresses the latest studies on vitamin D deficiency and the discrepancies that currently exist regarding its treatment. The advances made in epigenetics allow us to present this approach as a possible biomarker of multiple sclerosis. An account is provided to explain the growing importance of imaging techniques to detect atrophy and other phenomena that occur during the disease, such as changes in iron concentration or remyelination processes, which allow us to further our understanding of the mechanisms of cortical pathology, and the dimensionality of neurodegeneration during its course. Findings related to immunological mechanisms and advances in potential antigen-specific therapies are discussed. The contribution presents the latest studies on the assessment of cognitive impairment and its rehabilitation, which are becoming increasingly important due to the high prevalence of these disorders and the absence of their systematic assessment in clinical practice. Finally, the unmet social and health needs of multiple sclerosis patients in our country are presented, with emphasis on the current deficits in the system of social protection.

Objetivo. Sintetizar el contenido presentado en la XII edición de la Reunión Post-ECTRIMS, que tuvo lugar en septiembre de 2019 en Sevilla y que se presenta en dos partes. Desarrollo. Esta primera parte aborda los últimos estudios sobre el déficit de vitamina D y las discrepancias existentes acerca de su tratamiento. Los avances en epigenética realizados permiten presentar esta aproximación como un posible biomarcador de la esclerosis múltiple. Se explica el creciente protagonismo de las técnicas de imagen para detectar la atrofia y otros fenómenos que acontecen durante la enfermedad, como los cambios en la concentración de hierro o los procesos de remielinización, que nos permiten ganar comprensión sobre los mecanismos de la patología cortical, y sobre la dimensionalidad de la neurodegeneración durante su evolución. Se discuten los hallazgos relacionados con los mecanismos inmunológicos y los avances realizados en las potenciales terapias específicas del antígeno. Se presentan los últimos estudios sobre la evaluación del deterioro cognitivo y su rehabilitación, que cobran cada vez más importancia por la alta prevalencia de estas alteraciones y por la ausencia de su evaluación sistemática en la práctica clínica. Por último, se exponen las necesidades sociosanitarias no cubiertas de los pacientes de esclerosis múltiple en nuestro país, poniendo el acento en los déficits actuales del sistema de protección social.

Review of the novelties presented at the 2018 ECTRIMS Congress: 11th Post-ECTRIMS Meeting (II). / Revision de las novedades presentadas en el Congreso ECTRIMS 2018: XI Reunion Post-ECTRIMS (II).

The Post-ECTRIMS Meeting was held for the eleventh consecutive year in October 2018 in Madrid, with the aim of analysing the advances made in multiple sclerosis that were highlighted at the latest ECTRIMS annual congress. Based on the issues discussed at this meeting, attended by the nation's foremost opinion leaders on multiple sclerosis, two review articles are presented. This second part includes the growing body of evidence confirming the safety of exposure to disease-modifying treatments in women planning a pregnancy, and the beneficial effect of breastfeeding, provided that the disease is not very active. It addresses data showing how the application of the 2017 McDonald criteria in the paediatric population has significantly improved diagnosis compared to the previous criteria. With regard to progressive multiple sclerosis, the results of neuroprotective drugs are inconclusive, but biomarkers are proposed to improve the evaluation of the therapeutic response. Studies on myelin repair treatments suggest that remyelination in multiple sclerosis is possible. Likewise, there are favourable indications for haematopoietic stem cell transplantation, provided that patients are selected appropriately. On the other hand, we also conduct a review of the similarities and differences of the recommendations in the new clinical practice guidelines. Finally, the positive results of cognitive and motor rehabilitation with the use of new technologies point to the systematic incorporation of these tools in the treatment of the disease in the near future.

TITLE: Revision de las novedades presentadas en el Congreso ECTRIMS 2018: XI Reunion Post-ECTRIMS (II).La reunion Post-ECTRIMS se celebro por undecimo año consecutivo el pasado octubre de 2018 en Madrid, con el objetivo de analizar los avances en esclerosis multiple destacados en el ultimo congreso anual ECTRIMS. Fruto de esta reunion, formada por los lideres de opinion en esclerosis multiple de ambito nacional, se presentan dos articulos de revision. En esta segunda parte, se incluye el creciente numero de evidencias que confirman la seguridad de la exposicion a los tratamientos modificadores de la enfermedad en mujeres que planifican un embarazo, y el efecto beneficioso de la lactancia, siempre y cuando la enfermedad no este muy activa. Se abordan los datos que muestran como la aplicacion de los criterios de McDonald de 2017 en poblacion pediatrica ha mejorado considerablemente el diagnostico en comparacion con los criterios anteriores. En cuanto a la esclerosis multiple progresiva, los resultados de los farmacos neuroprotectores son poco concluyentes, pero se proponen biomarcadores para mejorar la evaluacion de la respuesta terapeutica. Los estudios sobre tratamientos de reparacion de la mielina sugieren que la remielinizacion en la esclerosis multiple es posible. De igual manera, se exponen indicios favorables sobre el trasplante de celulas madre hematopoyeticas, siempre que se seleccione adecuadamente a los pacientes. Por otro lado, se revisan las similitudes y diferencias de las recomendaciones de las nuevas guias de practica clinica publicadas. Por ultimo, los resultados positivos de la rehabilitacion cognitiva y motora con el uso de las nuevas tecnologias vaticinan la incorporacion sistematica de estas herramientas en el tratamiento de la enfermedad en un futuro proximo.

[Review of the novelties presented at the 2018 ECTRIMS Congress: 11th Post-ECTRIMS Meeting (I)]. / Revision de las novedades presentadas en el congreso ECTRIMS 2018: XI Reunion Post-ECTRIMS (I).

The Post-ECTRIMS Meeting is an emblematic event in Spain which seeks to review and disseminate the main advances in multiple sclerosis presented at the ECTRIMS annual congress. In October 2018, the eleventh Post-ECTRIMS meeting was held in Madrid and was attended by the country's leading experts in multiple sclerosis. As a result of this meeting, we present two articles which outline the most interesting novelties discussed there. This first part includes the latest results obtained regarding the influence of modifiable and non-modifiable risk factors in multiple sclerosis, with emphasis on the progress made in the field of genetics, where the discovery of genes associated with multiple sclerosis has increased exponentially. The complexity of the immune system is addressed and some contributions are made on autoimmunity mechanisms, in which bidirectional relations are observed between immune cells and cells residing in the central nervous system, such as microglial cells and astrocytes. Biomarkers, both in serum and cerebrospinal fluid as well as in imaging, are gaining more and more attention due to their current and, above all, potential role in the diagnosis and prognosis of the disease and in the evaluation of the efficacy of treatments. Finally, the observations made regarding changes in structural and functional connectivity in patients and their relationship with clinical alterations are presented.

En octubre de 2018, la reunion Post-ECTRIMS celebro en Madrid su undecima edicion, contando con los mayores expertos de ambito nacional en esclerosis multiple. Como resultado de esta reunion, se presentan dos articulos donde se recogen las novedades mas destacadas en la misma. En esta primera parte se incluyen los ultimos resultados sobre la influencia de los factores de riesgo modificables y no modificables en la esclerosis multiple, destacando los progresos realizados en el ambito genetico, donde el descubrimiento de genes asociados a la esclerosis multiple ha aumentado exponencialmente. Se aborda la complejidad del sistema inmune y se realizan algunas aportaciones sobre los mecanismos de autoinmunidad, en los que se observan relaciones bidireccionales entre las celulas inmunes y las celulas residentes del sistema nervioso central, como la microglia y los astrocitos. Los biomarcadores, tanto en suero y liquido cefalorraquideo como de imagen, ganan cada vez mas atencion por su papel actual, y sobre todo potencial, en el diagnostico y pronostico de la enfermedad y en la evaluacion de la eficacia de los tratamientos. Por ultimo, se presentan las observaciones realizadas respecto a los cambios en la conectividad estructural y funcional en los pacientes y su relacion con las alteraciones clinicas.

Neurofilament light chain levels in pregnant multiple sclerosis patients: a prospective cohort study.

BACKGROUND AND PURPOSE: Neurofilament light chain is a cytoskeletal protein of neurons. Its levels are increasingly recognized as measures of neuroaxonal damage. The aim of this study was to explore serum neurofilament light chain (sNfL) levels in multiple sclerosis (MS) patients and healthy controls during pregnancy and puerperium. METHODS: This was a prospective, longitudinal, single-center study. sNfL concentration was assessed using a highly sensitive single-molecule array during pregnancy and in puerperium, in a cohort of 39 pregnant patients with relapsing multiple sclerosis (P-MS). Twenty-one healthy pregnant women (HPW) served as a control group. Eight P-MS suffered relapses during pregnancy (P-MS-R) in the first or second trimesters. RESULTS: No differences in pregnancy and delivery data were observed between P-MS and HPW. P-MS showed higher sNfL values than HPW in the first trimester, independently of the presence (P = 0.002) or not (P = 0.02) of relapses during pregnancy. However, in the third trimester, only P-MS-R showed higher sNfL values than HPW (P = 0.001). These differences extended to the puerperium, where P-MS-R showed higher sNfL values than those with no relapses during gestation (P = 0.02). CONCLUSION: These data strongly suggest that sNfL levels reflect MS activity during pregnancy. Additionally, the absence of relapses during pregnancy may have a beneficial effect on neurodegeneration during puerperium.

Classification of radiologically isolated syndrome and clinically isolated syndrome with machine-learning techniques.

BACKGROUND AND PURPOSE: The unanticipated detection by magnetic resonance imaging (MRI) in the brain of asymptomatic subjects of white matter lesions suggestive of multiple sclerosis (MS) has been named radiologically isolated syndrome (RIS). As the difference between early MS [i.e. clinically isolated syndrome (CIS)] and RIS is the occurrence of a clinical event, it is logical to improve detection of the subclinical form without interfering with MRI as there are radiological diagnostic criteria for that. Our objective was to use machine-learning classification methods to identify morphometric measures that help to discriminate patients with RIS from those with CIS. METHODS: We used a multimodal 3-T MRI approach by combining MRI biomarkers (cortical thickness, cortical and subcortical grey matter volume, and white matter integrity) of a cohort of 17 patients with RIS and 17 patients with CIS for single-subject level classification. RESULTS: The best proposed models to predict the diagnosis of CIS and RIS were based on the Naive Bayes, Bagging and Multilayer Perceptron classifiers using only three features: the left rostral middle frontal gyrus volume and the fractional anisotropy values in the right amygdala and right lingual gyrus. The Naive Bayes obtained the highest accuracy [overall classification, 0.765; area under the receiver operating characteristic (AUROC), 0.782]. CONCLUSIONS: A machine-learning approach applied to multimodal MRI data may differentiate between the earliest clinical expressions of MS (CIS and RIS) with an accuracy of 78%.

[Efficacy and safety of fingolimod in routine clinical practice in patients with relapsing-remitting multiple sclerosis in Spain: an intermediate analysis of the MS NEXT study]. / Efectividad y seguridad del fingolimod en la practica clinica habitual en pacientes con esclerosis multiple remitente recurrente en España: analisis intermedio del estudio MS NEXT.

INTRODUCTION: Fingolimod is a disease modifying therapies, which has showed clinical efficacy and an acceptable safety profile in clinical trials with relapsing-remitting multiple sclerosis (RRMS) patients. AIM: To assess fingolimod effectiveness and safety in patients with RRMS in clinical practice. PATIENTS AND METHODS: We present an interim analysis (July 2015) of MS NEXT, an observational, retrospective and multicenter study. 442 patients were included (mean age: 41 ± 9 years; median baseline EDSS: 3.0; 70% female; 284 previously treated with first-line disease modifying therapies, 139 with natalizumab and 19 without a previous treatment; mean fingolimod treatment duration: 25 ± 9 months) treated with fingolimod from November 2011 and with at least 12 months follow-up. 56 neurology-unit Spanish hospitals enrolled patients. Basal clinical and demographic data were recorded. Relapses, EDSS scores and radiological activity were recorded at baseline and annually. Adverse events were also recorded during the follow-up period. RESULTS: After two years of follow-up: annual relapse rates decreased by 76%, the proportion of relapse-free patients was 67%, of disability progression-free patients confirmed at 3 months was 91%, of relapse and disability progression-free patients was 63%, of radiological activity-free patients was 50%, and the proportion of relapse, disability progression and radiological activity-free patients was 35%. Only 3.9% of patients discontinued fingolimod permanently during the first year of treatment. CONCLUSIONS: In this interim analysis, most of patients treated with fingolimod in clinical practice had a controlled clinical disease activity, stable disability progression and high persistency.

Genes differentially expressed by methylprednisolone in vivo in CD4 T lymphocytes from multiple sclerosis patients: potential biomarkers.

Intravenous methylprednisolone (IVMP) is the gold standard treatment in acute relapses of multiple sclerosis. Knowing the response to IVMP in advance could facilitate earlier selection of patients for subsequent courses of therapy. However, molecular mechanisms and changes in gene expression induced by methylprednisolone remain unknown. The aim of the study was to identify in vivo differentially expressed genes in relapsing-remitting multiple sclerosis patients after 3-6 days of treatment with IVMP. For this purpose, whole-genome transcription profiling of CD4+ T lymphocytes was performed before and after treatment with IVMP in 8 relapsing-remitting multiple sclerosis patients during relapse using Human GE 4x44K v2 microarrays. Differentially expressed genes were identified using a paired t test on GeneSpring v13.0 software. A P-value <0.001 and a twofold change were considered significant. Microarray data were confirmed using real-time PCR. Microarray revealed changes in gene expression: four genes were downregulated (B3GNT3, ZNF683, IFNG and TNF) and seven upregulated (DEFA4, CTSG, DEFA8P, AZU1, MPO, ELANE and PRTN3). Pathway analysis revealed the transforming growth factor-ß signaling pathway to be affected. Comparison with previously published data on in vitro methylprednisolone-regulated genes showed that SMAD7, TNF and CHI3L1 were also downregulated in vivo in relapsing-remitting multiple sclerosis patients. In summary, we performed the first in vivo transcriptome analysis in CD4+ T lymphocytes before and after the treatment with IVMP in patients with multiple sclerosis. Identification of differentially expressed genes in patients receiving IVMP could improve our understanding of the molecular mechanisms underlying the therapeutic effects of IVMP and highlight potential biomarkers of the response to IVMP.

Review of the novelties from the 32nd ECTRIMS Congress, 2016, presented at the 9th Post-ECTRIMS Meeting (II). / Revision de las novedades del XXXII Congreso ECTRIMS 2016, presentadas en la IX Reunion Post-ECTRIMS (II).

For the ninth year in a row the Post-ECTRIMS Meeting has been held in Madrid (Spain) with the aim of presenting and discussing the hottest issues debated at the ECTRIMS Congress by renowned specialists in multiple sclerosis in our country. One outcome of this scientific activity, endorsed by the Spanish Neurology Society, is this review article, which is published in two parts. This second part reflects the current controversy over the management of multiple sclerosis, especially as regards the progressive forms and their differential diagnosis. The work presents the latest advances in remyelination, where the use of the micropillar technique in laboratory stands out, and in neuroprotection, which is reviewed through a study of the optic nerve. Anti-CD20 antibodies are a very promising development and we find ourselves before a new mechanism of action and therapeutic target in cells to which little attention has been paid to date. Another notable fact is the high correlation between the levels of neurofilaments in cerebrospinal fluid and in serum, which could make it possible to avoid the use of cerebrospinal fluid as a biological sample in future studies of biomarkers. The review also provides a preview of the advances in clinical research, which will converge in clinical practice in the future, thereby conditioning the steps that should be taken in the therapeutic management of multiple sclerosis.

TITLE: Revision de las novedades del XXXII Congreso ECTRIMS 2016, presentadas en la IX Reunion Post-ECTRIMS (II).Por noveno año consecutivo se ha celebrado en Madrid (España) la Reunion Post-ECTRIMS con el objetivo de presentar y discutir los temas mas debatidos en el congreso ECTRIMS de la mano de reconocidos especialistas en esclerosis multiple de nuestro pais. Fruto de esta reunion cientifica, avalada por la Sociedad Española de Neurologia, se genera este articulo de revision que sale publicado en dos partes. En esta segunda parte se pone de manifiesto la controversia actual en el manejo de la esclerosis multiple, especialmente en cuanto a formas progresivas y diagnostico diferencial se refiere. Se presentan los ultimos avances en remielinizacion, donde destaca el uso de la tecnica con micropilares en el laboratorio, y en neuroproteccion, la cual se revisa a traves del estudio del nervio optico. Los anticuerpos anti-CD20 ofrecen grandes expectativas, y estamos ante un nuevo mecanismo de accion y diana terapeutica en unas celulas a las que les habiamos prestado poca atencion hasta la fecha. Otro hecho destacable es la elevada correlacion entre los niveles de neurofilamentos en el liquido cefalorraquideo y el suero, que podria evitar el uso del liquido cefalorraquideo como muestra biologica en futuros estudios de biomarcadores. Tambien se anticipan los avances en investigacion clinica que en el futuro acabaran convergiendo en la practica clinica, condicionando los pasos que se deberan seguir en el abordaje terapeutico de la esclerosis multiple.

One outcome of this scientific activity, endorsed by the Spanish Neurology Society, is this review article, which is published in two parts. This first part addresses family planning, pregnancy management and the role of breastfeeding in women with multiple sclerosis. Attention is drawn to the paediatric population, to magnetic resonance imaging features and to the genetic-environmental risk factors for developing the disease in children, without neglecting the risk factors for development in adults. The review updates the epidemiology of cognitive deterioration in patients with multiple sclerosis, the advantages and disadvantages of available assessment tools, and current management approaches, while also insisting on the importance of cognitive involvement during the course of the disease. Furthermore, the concept of individualised, precision medicine is introduced, from the diagnosis of the disease until its treatment, with the controversies that inevitably arise in patient management, above all with regard to the change of treatment and the handling of associated risks.
