ABSTRACT
Thyroid cancer is the single most prevalent endocrine malignancy; differentiated thyroid cancer (DTC) accounts for more than 90 % of all malignancies and its incidence has been rising steadily. For more patients, surgical treatment, radioactive iodine (RAI) ablation, and thyroid-stimulating hormone (TSH) suppressive therapy achieve an overall survival (OS) rate of 97.7 % at 5 years. Nevertheless, locoregional recurrence occurs in up to 20 % and distant metastases in approximately 10 % at 10 years. Two-thirds of these patients will never be cured with radioactive iodine therapy and will become RAI-refractory, with a 3-year OS rate of less than 50 %. Over the last decade, substantial progress has been made in the management of RAI-refractory DTC. Given the controversy in some areas, the Spanish Task Force for Thyroid Cancer on behalf of Spanish Society of Endocrinology Thyroid Cancer Working Group (GTSEEN) and the Spanish Rare Cancer Working Group (GETHI) have created a national joint task force to reach a consensus addressing the most challenging aspects of management in these patients. In this way, multidisciplinary management should be mandatory and nuclear medicine targeted therapy, novel molecular targeted agents, and combinations are currently changing the natural history of RAI-refractory DTC (AU)

Anaplastic thyroid cancer (ATC) is the most aggressive solid tumor and almost uniformly lethal in humans. The Boards of the Thyroid Cancer Group of the Spanish Society of Endocrinology and Nutrition and the Grupo Español de Enfermedades Huérfanas e Infrecuentes of the Spanish Society of Oncology requested that an independent task force draft a more comprehensive consensus statement regarding ATC. All relevant literature was reviewed, including serial PubMed searches together with additional articles. This is the first, comprehensive Spanish consensus statement for ATC and includes the characteristics, diagnosis, initial evaluation, treatment goals, recommendations and modalities for locoregional and advanced disease, palliative care options, surveillance, and long-term monitoring. Newer systemic therapies are being investigated, but more effective combinations are needed to improve patient outcomes. Though more aggressive radiotherapy has reduced locoregional recurrences, median overall survival has not improved in more than 50 years (AU)

Background: Of all thyroid cancers,< 5 % are medullary (MTC). It is a well-characterized neuroendocrine tumor arising from calcitonin-secreting C cells, and RET gene plays a central role on its pathogeny. Methods: The electronic search was conducted using MEDLINE (PubMed), EMBASE and Cochrane Central Register of Controlled Trials. Quality assessments of selected current articles, guidelines and reviews of MTC were performed. Results: This consensus updates and summarizes biology, treatment and prognostic considerations of MTC. Conclusions: Multidisciplinary teams and specialized centers are recommended for the management of MTC patients. In the metastatic setting, those patients with large volume of disease are candidates to start systemic treatment mainly if they are symptomatic and the tumor has progressed in the last 12-14 months. Wait and see strategy should be offered to patients with: disseminated disease with only high levels of calcitonin and no macroscopic structural disease, low burden and absence of progression (AU)

El tratamiento con insulina puede ser necesario en la diabetes tipo 2, dado que muchos pacientes, con el tiempo, no consiguen alcanzar o mantener los objetivos glucémicos para prevenir las complicaciones crónicas asociadas a la hiperglucemia sostenida. Inicialmente, la adición de insulina basal al tratamiento previo con agentes orales suele ser la pauta más habitual. Esta estrategia se basa en el control óptimo de la glucemia en ayunas. Sin embargo, un porcentaje significativo de pacientes no consiguen alcanzar o mantener el objetivo de HbA1c <=7%, debido a que presentan elevaciones excesivas de la glucemia posprandial. En consecuencia, el paso siguiente en la intensificación deltratamiento podría ser la adición de una dosis única de insulina prandial antes de la comida que provoca la mayor excursión posprandial (estrategia basal plus), manteniendo el tratamiento previo con insulina basal y agentes orales. Este régimen ha demostrado ser sencillo, eficaz y adecuado para un gran número de pacientes. Además, en caso necesario, facilita la introducción progresiva de inyecciones adicionales de insulina prandial hasta una estrategia bolo basal. En este artículo se resumen las recomendaciones de un grupo de trabajo multidisciplinar para una adecuada implementación de la estrategia basal plus en la práctica clínica habitual (AU)
Insulin treatment may be necessary in type 2 diabetes, because many patients are not able overthe time to achieve or maintain glycemic targets to prevent chronic complications associated to sustained hyperglycemia. Initially, addition of basal insulin to previous treatment with oral agentsis the most commonly used regimen. This strategy is based on optimal control of fasting plasma glucose. However, a significant proportion of patients does not achieve or maintain HbA1c target <=7%, because they show excessive postprandial glucose values. Therefore, the next step for intensification of treatment might be the addition of a single dose of prandial insulin before the main meal, which is associated with the greatest postprandial glucose excursion (basal plus strategy), maintaining previous treatment with basal insulin and oral agents. This regimen has demonstrated to be easy to use, effective and appropriate for many patients. Furthermore, if necessary, it makes easier progressive introduction of additional injections of prandial insulin until the basal bolus strategy. In this manuscript, recommendations from a multidisciplinary working group are summarized for an adequate implementation of the basal plus strategy in the routine clinical practice (AU)
