Manejo de los pacientes con cáncer de próstata localizado y recurrencia bioquímica en España: encuesta médica / Management of patients with localized prostate cancer and biochemical recurrence in Spain: A medical survey

Introducción El tratamiento de los pacientes con cáncer de próstata (CaP) está establecido en las guías de práctica clínica, las cuales se basan en estudios aleatorizados según el nivel de evidencia. En España se desconoce el grado de cumplimiento de estas guías en la práctica clínica. Objetivos Describir los perfiles de los pacientes con CaP en el momento del diagnóstico y el manejo de los pacientes con CaP localizado y con recurrencia bioquímica (RBQ) en España. Materiales y métodos Se realizó una encuesta médica en 3 especialidades médicas (85 urólogos [URO], 64 oncólogos radioterápicos [OR] y 21 oncólogos médicos [OM]). Para este estudio se elaboraron 3 cuestionarios, 2 con 22 preguntas (URO y OR) y uno con 21 preguntas (OM). Resultados La incidencia anual de CaP en los hospitales participantes (N=131) fue de 24.057 casos. La incidencia anual extrapolada a España fue de 40.531 casos. La prevalencia estimada de CaP en España es de 221.689. Cabe destacar que el 79 y el 80% de los pacientes atendidos por URO y OR, respectivamente, presentaban CaP localizado en el momento del diagnóstico. La biopsia fue la prueba diagnóstica más utilizada en las 3 especialidades, seguida de la tomografía computarizada abdominopélvica. Más del 90% de los pacientes con RBQ se sometieron a pruebas estándar. Las técnicas de imagen de nueva generación y la PET con colina/PSMA se siguen utilizando en menor medida. Actualmente, la mayoría de los pacientes con CaP localizado reciben tratamiento con cirugía o radioterapia, pero en el caso de los pacientes con RBQ, los URO y OR prefieren la radioterapia y los OM la terapia de privación androgénica exclusiva o combinada. Conclusión Este estudio describe los perfiles de los pacientes en el momento del diagnóstico y proporciona una visión general del manejo terapéutico actual del CaP localizado y con RBQ en la práctica clínica en España.

Introduction The management of patients with prostate cancer (PCa) is established in clinical practice guidelines, which are based on randomized studies according to the level of evidence. In Spain, the degree of compliance with these guidelines in clinical practice is unknown. Objectives To describe the profiles of PCa patients at the time of diagnosis and the management of patients with localized PCa and those with biochemical recurrence (BCR) in Spain. Materials and methods A medical survey was conducted in specialized care (85 urologists [UROs], 64 radiation oncologists [ROs], and 21 medical oncologists [MOs]). Three questionnaires were developed for this study with 22 (UROs and ROs) or 21 questions (MOs). Results The annual incidence of PCa was 24,057 in participating hospitals (N=131). The extrapolated annual incidence in Spain is 40,531 cases. The estimated prevalence of PCa in Spain is 221,689. Of note, 79 and 80% of patients seen by UROs and ROs, respectively had localized PCa at diagnosis. Biopsy was the most used diagnostic test among the 3 specialties, followed by abdominopelvic computer tomography. More than 90% of patients with BCR underwent standard tests. Next generation imaging tests and PET-choline/PSMA are still used residually. Most patients with localized PCa are currently treated with either surgery or radiotherapy, while for BCR patients, UROs and ROs prefer radiotherapy and MOs androgen deprivation therapy alone or in combination. Conclusion This study describes patient profiles at the time of diagnosis and provides an overview of the current therapeutic management of localized PCa and BCR in clinical practice in Spain. (AU)

INTRODUCTION: The management of patients with prostate cancer (PCa) is established in clinical practice guidelines, which are based on randomized studies according to the level of evidence.

Three questionnaires were developed for this study with 22 (UROs and ROs) or 21 questions (MOs). RESULTS: The annual incidence of PCa was 24,057 in participating hospitals (N = 131). The extrapolated annual incidence in Spain is 40,531 cases. The estimated prevalence of PCa in Spain is 221,689.

Thyroid signaling in immune organs and cells of the teleost fish rainbow trout (Oncorhynchus mykiss).

Thyroid hormones are involved in modulating the immune system in mammals. In contrast, there is no information on the role played by these hormones in the immune system of teleost fish. Here we provide initial evidence for the presence of active thyroid signaling in immune organs and cells of teleosts. We demonstrate that immune organs (head kidney and spleen) and isolated leukocytes (from head kidney and peripheral blood) of the rainbow trout (Oncorhynchus mykiss) express both thyroid receptor α (THRA) and ß (THRB). Absolute mRNA levels of THRA were significantly higher than those of THRB. THRA showed higher expression in immune organs and isolated immune cells compared to the reference organ, liver, while THRB showed the opposite. In vivo exposure of trout to triiodothryronine (T3) or the anti-thyroid agent propylthiouracil (PTU) altered THR expression in immune organs and cells. Effect of T3 and PTU over the relative expression of selected marker genes of immune cell subpopulations was also studied. Treatments changed the relative expression of markers of cytotoxic, helper and total T cells (cd4, cd8a, trb), B lymphocytes (mIgM) and macrophages (csf1r). These findings suggest that the immune system of rainbow trout is responsive to thyroid hormones.

In vitro assessment of thyroidal and estrogenic activities in poultry and broiler manure.

Among the many chemicals found in avian manure, endocrine disruptors (EDs), of natural or anthropogenic origin, are of special environmental concern. Nowadays, an increasing amount of estrogens is being released into the environment via the use of manure to fertilize agricultural land. While most research in this field has focused on estrogenic phenomena, little is known about alterations related to other endocrine systems, such as the thyroidal one. Here we simultaneously assessed the potential estrogenic and thyroidal activity of poultry and broiler litter manure using in vitro approaches based on estrogen receptor (Er) and thyroid receptor (Tr) transactivation assays. In addition, leaching experiments were performed to assess whether the EDs present in the manure pass through a soil column and potentially reach the groundwater. Manure from four broiler and four poultry farms was collected in two sampling campaigns carried out in two seasons (fall and spring). Extracts from broiler and poultry manure exhibited strong thyroidal activity. Only poultry manure showed estrogenic activity, which is consistent with the low levels of estrogens expected in hatchlings. Leakage experiments were performed in columns with two kinds of arable soils: sandy and loamy. No estrogenicity or thyroidal activity was detectable in soils treated with the manure or in the corresponding leachates. These results indicate that substances with estrogenic or thyroidal activity were degraded in the soil under our experimental conditions. However, the long-term effects associated with the constant and intensive application of manure to agricultural land in some regions require further research.
