          Abstract

          RESUMEN: Introducción y objetivo: La punción aspiración con aguja fina es el método de elección para el diagnóstico del nódulo tiroideo, permitiendo discriminar entre lesiones malignas y benignas en un alto porcentaje de pacientes. Sin embargo, las categorías diagnósticas I (No diagnóstico o insatisfactorio) y III (Atipia o Lesión folicular de Significado Incierto) del Sistema Bethesda suponen un reto en el manejo de los nódulos tiroideos. El objetivo del presente trabajo es exponer las opciones de que se disponen en el momento actual para intentar incrementar la rentabilidad de estos diagnósticos. Síntesis: En primer lugar, el abordaje multidisciplinar de los casos, la posibilidad de seguimiento, la repetición de la punción aspiración, la complementación del diagnóstico incorporando técnicas inmunohistoquímicas o moleculares, y finalmente la posibilidad de realizar una biopsiacilindro. Conclusiones: Estas alternativas son especialmente útiles en la categoría diagnóstica III, mientras que se prefiere la opción de seguimiento o repetición de PAAF en la categoría diagnóstica I.

          SUMMARY: Introduction and objective: Fine-needle aspiration (FNA) has a primary role in the diagnosis of thyroid nodules. FNA allows us to differentiate benign lesions from malignant ones in most of the cases. However, management of Bethesda System diagnostic categories I (Nondiagnostic or Unsatisfactory) and III (Atypia of Undetermined Significance or Follicular Lesion of Undetermined Significance) are a clinical challenge. The aim of this work is to expose the options we have to improve the diagnosis of those categories using a multidisciplinary approach, an active follow-up, repeating FNA, applying immunohistochemical and/or molecular technics or even perform a core needle biopsy. Synthesis: Conclusions: Some or all of these choices are especially useful to identify category III, but active follow-up or additional FNA are preferred to detect category I.

          Global Cancer Statistics 2018: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries

          This article provides a status report on the global burden of cancer worldwide using the GLOBOCAN 2018 estimates of cancer incidence and mortality produced by the International Agency for Research on Cancer, with a focus on geographic variability across 20 world regions. There will be an estimated 18.1 million new cancer cases (17.0 million excluding nonmelanoma skin cancer) and 9.6 million cancer deaths (9.5 million excluding nonmelanoma skin cancer) in 2018. In both sexes combined, lung cancer is the most commonly diagnosed cancer (11.6% of the total cases) and the leading cause of cancer death (18.4% of the total cancer deaths), closely followed by female breast cancer (11.6%), prostate cancer (7.1%), and colorectal cancer (6.1%) for incidence and colorectal cancer (9.2%), stomach cancer (8.2%), and liver cancer (8.2%) for mortality. Lung cancer is the most frequent cancer and the leading cause of cancer death among males, followed by prostate and colorectal cancer (for incidence) and liver and stomach cancer (for mortality). Among females, breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death, followed by colorectal and lung cancer (for incidence), and vice versa (for mortality); cervical cancer ranks fourth for both incidence and mortality. The most frequently diagnosed cancer and the leading cause of cancer death, however, substantially vary across countries and within each country depending on the degree of economic development and associated social and life style factors. It is noteworthy that high-quality cancer registry data, the basis for planning and implementing evidence-based cancer control programs, are not available in most low- and middle-income countries. The Global Initiative for Cancer Registry Development is an international partnership that supports better estimation, as well as the collection and use of local data, to prioritize and evaluate national cancer control efforts.

            2015 American Thyroid Association Management Guidelines for Adult Patients with Thyroid Nodules and Differentiated Thyroid Cancer: The American Thyroid Association Guidelines Task Force on Thyroid Nodules and Differentiated Thyroid Cancer.

            Thyroid nodules are a common clinical problem, and differentiated thyroid cancer is becoming increasingly prevalent. Since the American Thyroid Association's (ATA's) guidelines for the management of these disorders were revised in 2009, significant scientific advances have occurred in the field. The aim of these guidelines is to inform clinicians, patients, researchers, and health policy makers on published evidence relating to the diagnosis and management of thyroid nodules and differentiated thyroid cancer.

              Integrated genomic characterization of papillary thyroid carcinoma.

              (2014)
              Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. Here, we describe the genomic landscape of 496 PTCs. We observed a low frequency of somatic alterations (relative to other carcinomas) and extended the set of known PTC driver alterations to include EIF1AX, PPM1D, and CHEK2 and diverse gene fusions. These discoveries reduced the fraction of PTC cases with unknown oncogenic driver from 25% to 3.5%. Combined analyses of genomic variants, gene expression, and methylation demonstrated that different driver groups lead to different pathologies with distinct signaling and differentiation characteristics. Similarly, we identified distinct molecular subgroups of BRAF-mutant tumors, and multidimensional analyses highlighted a potential involvement of oncomiRs in less-differentiated subgroups. Our results propose a reclassification of thyroid cancers into molecular subtypes that better reflect their underlying signaling and differentiation properties, which has the potential to improve their pathological classification and better inform the management of the disease.
