ABSTRACT

SUMMARY Paraneoplastic syndromes are a heterogeneous group of malignant diseases caused by events which involve endocrine, immune and metabolic aspects and whose symptoms vary according to the substance produced and the primary tumor. Hypercalcemia is a frequent complication in cancer patients. Prognosis of cancer patients with hypercalcemia is usually poor. A factor called parathyroid hormone related peptide, whose actions are similar to those of the parathyroid hormone, is thought to be the most common cause of malignancy associated hypercalcemia. Non-islet hypoglycemic cell tumor consists of a rare syndrome characterized by the presence of a solid tumor and severe fasting hypoglycemia determined by an insulin-independent pathway. We report a case of a 59-year-old-man with a renal tumor and a T-cell rich large B cell lymphoma who was hospitalized due to severe hypercalcemia and hypoglycemia. The laboratory examination reported hypercalcemia with inhibited PTH and hypoglycemia with inhibited insulin secretion, arriving to the conclusion of tumoral peptide production. He received denosumab and corticoid therapy. The patient died one month later despite initial improvement after medical treatment. While a single paraneoplastic manifestation may be expected in most tumors, the coexistence of two or more of them is rare, except in hepatocellular carcinomas, and it has not yet been described in renal tumors.

ABSTRACT

La incidencia del cáncer de tiroides ha aumentado significativamente en las últimas décadas en el resto del mundo. En Argentina no existe un registro nacional de cáncer por lo que la incidencia del mismo no puede establecerse. Por lo tanto, nuestro objetivo fue estimar la incidencia de cáncer de tiroides en la población de la Ciudad Autánoma de Buenos aires y Gran Buenos Aires así como la relación por género y la histología en el período de 2003 hasta 2011. Asumiendo que la población de afiliados a la Obra Social de la Policía Federal Argentina es representativa de los habitantes de Buenos Aires y el conurbano calculamos que la incidencia es de 6,51 casos/100.000 habitantes/año, con un incremento en 25 años mayor al doble, con predominio del carcinoma papilar frente al folicular.


Thyroid cancer incidence has significantly risen worldwide in the last decades. In Argentina, there is no national cancer registry; therefore its incidence can not be established. The objective of this study was to estimate the incidence of thyroid cancer in the population of Buenos Aires City and suburbs, and the relationship between gender and histology over the period 2003-2011. Assuming that the population affiliated to the Social Security of the Argentine Federal Police is representative of the inhabitants of Buenos Aires City and suburbs, we estimate an incidence of 6.51 cases/100,000 population/year, with an increasing incidence of almost double from 1981-1986 to 2003-2011. An increase in papillary thyroid cancer was mainly responsible for this rising trend. Incidence rates were higher for females (11.76/100,000 women) compared to those for males (2.65/100,000 men). Among men and women of all ages, the highest rate of incidence was for tumor size < 1 cm.

ABSTRACT

Las patologías tiroideas son frecuentes y afectan alrededor del 10% de la población fértil femenina. El hipotiroidismo y la enfermedad tiroidea autoinmune traen aparejados trastornos de la fertilidad e implantación y desarrollo del embarazo. Durante el embarazo la glándula tiroides es puesta a prueba, poniéndose en marcha distintos mecanismos adaptativos. Se debe resaltar la importancia de un aporte suficiente de yodo antes y durante el embarazo. El adecuado funcionamiento tiroideo, tanto materno como fetal, juegan un rol fundamental para la normal evolución del embarazo y del desarrollo neuropsicointelectual del feto, ya que una disminución aún leve de la función tiroidea en la primera mitad del embarazo puede tener secuelas a largo plazo. Las hormonas tiroideas son fundamentales para el normal desarrollo del SNC y del cerebro fetal. Además de las complicaciones fetales, las pacientes hipotiroideas tienen mayores complicaciones en el embarazo tales como aborto, parto prematuro, retardo del crecimiento intrauterino y bajo peso al nacer. Sería ideal que la paciente hipotiroidea programe su embarazo, se halle adecuadamente tratada y con un control estricto durante el embarazo. Si bien no hay consenso para el screnning de rutina, hay grupos que postulan la utilidad de incluir un dosaje de TSH y ATPO en el primer trimestre del embarazo. El diagnóstico precoz y su adecuado tratamiento evitarán complicaciones muchas veces irreversibles en el embarazo y en el desarrollo neurológico fetal.
