Incidencia, prevalencia y patrones de tratamiento del cáncer de próstata metastásico hormonosensible en España: Estudio ECHOS / Incidence, prevalence, and treatment patterns in metastatic hormone-sensitive prostate cancer in Spain: ECHOS study

Introducción y objetivo: El manejo de los pacientes con cáncer de próstata hormonosensible metastásico (CPHSm) ha cambiado en los últimos años debido a la autorización de nuevos medicamentos. El objetivo fue caracterizar la prevalencia, incidencia y patrones de tratamiento para el CPHSm en España.Pacientes y métodos: Estudio multicéntrico, observacional, longitudinal, retrospectivo en condiciones de práctica clínica habitual con pacientes con CPHSm atendidos en hospitales españoles entre 2015 y 2019 (estudio ECHOS). Las historias clínicas se extrajeron de la base de datos BIG-PAC (geográficamente representativa).Resultados: Se incluyeron los datos de 379 hombres con CPHSm. La prevalencia varió entre 12,2-14,6%. Hubo de 671 a 824 nuevos casos anualmente, con una tendencia creciente. La incidencia media en el periodo del estudio fue de 2,5%, con valores anuales en el rango 2,2-3%. Los nuevos casos anuales de pacientes de novo y recurrentes osciló en el rango 7-11 y 77-104, respectivamente, sin tendencia observada. Mayoritariamente eran pacientes recurrentes (91%) y de alto volumen tumoral (68,6%). La primera línea de tratamiento fue la combinación de docetaxel y terapia de deprivación de andrógenos (TDA) (53%), seguida por TDA sola (23,8%), combinación de TDA y abiraterona (11,1%) y radioterapia (8,6%). En los 12 meses anteriores al diagnóstico de metástasis, la mayoría se sometieron a una prostatectomía (84,9%). El resto había recibido radioterapia (12%) o no recibieron tratamiento (3,8%).Conclusiones: El estudio ECHOS proporciona datos epidemiológicos y patrones de tratamiento actuales en la práctica clínica en pacientes con CPHSm en España. Los resultados obtenidos destacan la necesidad médica de terapias dirigidas. (AU)

Introduction and objective: The management of patients with metastatic hormone-sensitive prostate cancer (mHSPC) has changed in recent years due to the approval of new drugs. The aim of this study was to evaluate the prevalence, incidence, and treatment patterns in mHSPC in Spain.Patients and methods: Multicenter, observational, longitudinal, retrospective study in routine clinical practice of patients diagnosed with mHSPC treated in Spanish hospitals between 2015 and 2019 (ECHOS study). Electronic medical records were extracted from BIG-PAC database, which contains geographically representative Spanish centers.Results: Data from 379 men with mHSPC were included. The prevalence of mHSPC ranged between 12.2-14.6% per year, representing from 671 to 824 annual cases with an increasing trend. The mean incidence along the 4-year period was 2.5%, with annual incidence ranging 2.2-3.0%. New annual cases of de novo and recurrent disease ranged between 7-11 and 77-104, respectively, with no trend being observed. These patients were mostly recurrent (91%) with high-volume disease (68.6%). The most common first-line therapy was ADT combined with docetaxel (53%), followed by ADT alone (23.8%), combination of ADT and abiraterone (11.2%), and radiotherapy (8.6%). In the last 12 months before diagnosis of metastasis, most men had been submitted to radical prostatectomy (84.9%). The remaining patients had received radiotherapy (12%) or no treatment at all (3.8%).Conclusions: The ECHOS study provides epidemiologic data and current patterns of treatment in clinical practice of patients with mHSPC in Spain. These results emphasize the medical need of targeted treatments in these clinical settings. (AU)

Leukocyte and platelet counts as prognostic values of testicular germ cell tumours. / Valor pronóstico del recuento de leucocitos y plaquetas, en tumores testiculares de células germinales.

INTRODUCTION: The immune system plays an essential role in the organism's response to cancer. Several haematological markers can influence prognosis and survival of patients. The objective of this study is to determine their prognostic value in testicular germ cell tumours. MATERIAL AND METHODS: Retrospective cohort study on 164 patients with germ cell tumours. Clinical, analytical, histological and evolutionary data were collected. The absolute neutrophil and absolute platelet counts, neutrophil-lymphocyte (NLR), platelet-lymphocyte and lymphocyte-monocyte ratios were estimated at diagnosis. The association that these markers can have with the classic prognostic factors, as well as their effect on prognosis and survival, have been analysed. RESULTS: 17.7% had NLR>4 and 14.6% ANC>8000/µL. These patients presented higher percentages of residual disease and stage II-III tumours. Patients with elevated absolute neutrophil showed also higher percentages of progression and exitus. 7.3% presented absolute platelet >400000/µL. These patients obtained higher rates of residual disease, nonseminomatous and stage III tumours. 28.4% showed platelet-lymphocyte values>150. This data was associated to higher percentages of residual disease, progression, stage II and III tumours and seminomatous tumours. 83.3% had an lymphocyte-monocyte >3. These patients presented: higher tumour markers in normal range, decreased residual disease rates and higher percentages of stage I and II tumours. The mean survival time was shorter in patients with NLR>4 and absolute neutrophil >8,000/µL. The ROC curves showed significance in the prediction of progression and values of lymphocyte-monocyte >3, and prediction of survival and values NLR>4. CONCLUSION: Our results indicate that the analysed haematological markers are associated with poor prognoses at diagnosis. Therefore, their use in daily clinical practice can be a valuable tool in the diagnosis and prognosis of patients with testicular germ cell tumours.

Conducta de los profesionales sanitarios ante las recomendaciones de profilaxis de endocarditis infecciosa en nuestro medio: ¿se siguen las guías? / Behaviour of health professionals concerning the recommendations for prophylaxis for infectious endocarditis in our setting: Are the guidelines followed?

Objetivos. Las pautas de profilaxis de endocarditis infecciosa recomendadas por las guías de práctica clínica han cambiado recientemente. Se desconoce en nuestro medio si se siguen correctamente las pautas actuales. Nuestro objetivo es describir las actitudes de diferentes profesionales sanitarios ante ellas. Material y métodos. Hemos realizado una encuesta en Córdoba, mediante un cuestionario online con 16 ítems sobre este tema. Se seleccionó aleatoriamente una muestra de 180 profesionales (20 cardiólogos, 80 dentistas, 80 médicos de atención primaria), de la cual contestaron 173. Resultados. La mitad eran varones, teniendo más de 20 años de ejercicio profesional el 52%. El 88,3% consideró que la profilaxis de endocarditis es efectiva (cardiólogos, 77,8%, dentistas, 93,7%, p=0,086). En general, se realiza profilaxis en las situaciones de riesgo claramente establecidas (>90% de los encuestados), pero también en una alta proporción de casos sin riesgo de endocarditis, que oscila entre el 30 y el 60% según los procedimientos (más los dentistas, entre el 36 y 67%, seguidos de los médicos de atención primaria, entre el 28 y 59%). Las pautas antibióticas usadas son muy variadas, siendo los médicos de primaria los que se alejan más de lo recomendado (solo un 25,8% usaban la pauta recomendada, frente a un 54,4% de dentistas y un 72,2% de cardiólogos, p=0,002). Conclusiones. El seguimiento de las recomendaciones sobre profilaxis de endocarditis debe mejorarse en nuestro medio, observándose una tendencia, sobre todo en no cardiólogos, a una «sobreindicación» de la misma (AU)

Objectives. The prophylaxis regimens for infectious endocarditis recommended by the clinical practice guidelines have recently changed. We do not know whether the current regimens are correctly followed in our setting. Our objective was to describe the approaches of various health professionals concerning these guidelines. Material and methods. We conducted a survey in Cordoba, using a 16-item online questionnaire on this topic. We randomly selected a sample of 180 practitioners (20 cardiologists, 80 dentists and 80 primary care physicians), of whom 173 responded. Results. Half of the participants were men; 52% had more than 20 years of professional experience. Some 88.3% of the participants considered that prophylaxis of endocarditis is effective (77.8% of the cardiologists, 93.7% of the dentist; p=.086). In general, prophylaxis is performed in conditions of clearly established risk (>90% of those surveyed). However, prophylaxis is also performed in a high proportion of cases with no risk of endocarditis, varying between 30 and 60% according to the procedure (mostly the dentists, between 36 and 67%, followed by the primary care physicians, between 28 and 59%). The antibiotic regimens employed varied significantly. The primary care physicians were furthest from the recommended regimen (only 25.8% used the recommended regimen vs. 54.4% of dentists and 72.2% of cardiologists; p=.002). Conclusions. Compliance with the recommendations on prophylaxis for endocarditis should be improved in our setting. We observed a tendency, especially among noncardiologists, to 'overindicate' the prophylaxis (AU)

Economic assessment of fidaxomicin for the treatment of Clostridium difficile infection (CDI) in special populations (patients with cancer, concomitant antibiotic treatment or renal impairment) in Spain.

The objective of this paper was to assess the cost-utility of fidaxomicin versus vancomycin in the treatment of Clostridium difficile infection (CDI) in three specific CDI patient subgroups: those with cancer, treated with concomitant antibiotic therapy or with renal impairment. A Markov model with six health states was developed to assess the cost-utility of fidaxomicin versus vancomycin in the patient subgroups over a period of 1 year from initial infection. Cost and outcome data used to parameterise the model were taken from Spanish sources and published literature. The costs were from the Spanish hospital perspective, in Euros (€) and for 2013. For CDI patients with cancer, fidaxomicin was dominant versus vancomycin [gain of 0.016 quality-adjusted life-years (QALYs) and savings of €2,397 per patient]. At a cost-effectiveness threshold of €30,000 per QALY gained, the probability that fidaxomicin was cost-effective was 96 %. For CDI patients treated with concomitant antibiotic therapy, fidaxomicin was the dominant treatment versus vancomycin (gain of 0.014 QALYs and savings of €1,452 per patient), with a probability that fidaxomicin was cost-effective of 94 %. For CDI patients with renal impairment, fidaxomicin was also dominant versus vancomycin (gain of 0.013 QALYs and savings of €1,432 per patient), with a probability that fidaxomicin was cost-effective of 96 %. Over a 1-year time horizon, when fidaxomicin is compared to vancomycin in CDI patients with cancer, treated with concomitant antibiotic therapy or with renal impairment, the use of fidaxomicin would be expected to result in increased QALYs for patients and reduced overall costs.

C. albicans, C. parapsilosis and C. tropicalis invasive infections in the PICU: clinical features, prognosis and mortality.

Candida albicans remains the most common agent associated with invasive Candida infection (ICI), but with increasing number of non-albicans species. An epidemiological, observational study exploring host criteria, clinical characteristics and mortality of ICI was performed in 24 pediatric intensive care units (PICU) in Spain. Patients were analyzed in global and distributed by infecting species (for groups with ≥ 15 patients). A total of 125 ICI were included: 47 by C. albicans, 37 by C. parapsilosis, 19 by C. tropicalis, 4 C. glabrata, and 18 others. Up to 66% of ICI by C. albicans and 75.7% by C. parapsilosis occurred in children ≤ 24 months, while the percentage of children >60 months was higher in ICI by C. tropicalis. Bloodstream infection was most common among C. tropicalis (78.9%) or C. parapsilosis (83.8%) ICI, but urinary infections were almost as common as bloodstream infections among C. albicans ICI (31.9% and 38.3%, respectively). Fever refractory to antimicrobials was the most frequent host criterion (46.4% patients), but with equal frequency than prolonged neutropenia in C. tropicalis ICI. Thrombopenia was more frequent (p<0.05) in C. parapsilosis (60.7%) or C. tropicalis (66.7%) ICI than in C. albicans ICI (26.5%). Uremia was more frequent (p<0.05) in C. albicans (78.3%) or C. tropicalis (73.3%) than in C. parapsilosis ICI (40.7%). Multiple organ failure and heart insufficiency was higher in C. tropicalis ICI. Short duration (≤ 7 days) of PICU stay was more frequent in C. albicans ICI. Mortality rates were: 8.5% (C. albicans ICI), 13.5% (C. parapsilosis ICI) and 23.3% (C. tropicalis ICI). ICI by different Candida species showed different clinical profiles and mortality, making essential identification at species level.

[Renal epithelioid angiomyolipoma]. / Angiomiolipoma epitelioide renal.

Epithelioid angiomyolipoma of renal origin are a very rare variant of the classic angiomyolipomas but with the peculiarity to present malignant potential. Its diagnosis is usually after surgery because the tumor simulates both clinical and radiological features of renal cell carcinoma. We report a case of a 14 year old patient who was diagnosed with this disease as an incidental finding, and that after she underwent partial nephrectomy for three years is currently asymptomatic with no signs of disease recurrence.
