RESUMO

Recent investigations point at the stromal microenvironment to assess additional diagnostic information and provide new therapeutic targets in cancer. The aim of the study was to contribute to the characterization of the phenotype of cancer-associated fibroblasts (CAFs) in prostate cancer (PCa) compared with normal prostate-associated fibroblasts (NAFs) and fibroblasts from benign prostatic hyperplasia (BPH). Three patient populations were prospectively recruited: 23 patients with new localized PCa, 14 patients with advanced PCa treated with androgenic deprivation therapy (ADT), and 7 patients with BPH. Gene expression of 20 stroma-derived factors, including the androgen receptor (AR), chaperones (HSPA1A and HSF1), growth factors (FGF2, FGF7, FGF10, HGF, PDGFB, and TGFß), proteins implicated in invasion (MMP2, MMP9, and MMP11), inflammation (IL6, IL17RB, NFκB, and STAT3), and in-stroma/epithelium interaction (CDH11, CXCL12, CXCL14, and FAP), was evaluated. Localized PCa CAFs showed a significant higher expression of FGF7, IL6, MMP2, and MMP11 compared with NAFs or IL17RB compared with BPH fibroblasts, but significantly lower expression of FGF10 and IL17RB compared with NAFs or CXCL14 compared with BPH fibroblasts. In addition, CAFs from ADT-resistant PCa showed significantly higher MMP11 and NFκB but significant lower TGFß expression compared with CAFs from ADT-sensitive tumors. Our results contribute to defining the CAFs phenotypes associated to PCa progression, which may contribute to the diagnosis and design of alternative therapies in PCa.

RESUMO

OBJECTIVE: The increase of healthcare pressure in Emergency Departments compels us to have a better understanding of patients' characteristics and the pathology they consult for. This is the first study that estimates the waiting time in the emergency room and the factors that are independently related with hospital admission. METHODS: Descriptive and retrospective study of 2.741 patients who were admitted to the Emergency Department with genitourinary symptoms in 2011. Clinical and epidemiological features were reviewed. A multivariable study was performed to identify the factors related with the final resolution of patients, recurrence emergency attendance, and waiting time in the emergency room. RESULTS: Most of the patients were male (60.3%), being diagnosed with hematuria, acute urinary retention and genital pathology. Females complained more frequently for pyelonephritis, urinary tract infection and low-back pain. Male were hospitalized in greater proportion. Age, diagnosis of infection/sepsis or low-back pain, and yellow or orange MTS level were independent features for hospital admission. Also, in the univariate and multivariate study, age > 60 years (311 vs 220 min.), UTI/sepsis related diagnoses (300 vs 250 min.), and hospital admission as final resolution (440 vs 240 min.) had a significant influence in the waiting time in the Emergency Department. CONCLUSIONS: Age over 60 years, hospital admission as final resolution and infection/sepsis diagnosis were independent features for further waiting time in the Emergency Department. Persistent pain and symptoms of infection/sepsis behaved as independent features for hospital admission.


OBJETIVO: El aumento de la presión asistencial de los servicios de urgencias hospitalarios obliga a conocer las características de los pacientes y de los procesos por los que acuden. Este estudio es el primero que calcula tiempo de permanencia en urgencias y factores que se relacionan de manera independiente con ingreso hospitalario.MÉTODOS: Estudio descriptivo y retrospectivo de 2.741 pacientes que acudieron a Urgencias por sintomatología genitourinaria en el año 2011. Se examinaron rasgos clínicos y epidemiológicos. Se realizó un análisis multivariable para conocer los factores relacionados con la resolución final de los pacientes, recurrencia en la asistencia a urgencias y tiempo en urgencias. RESULTADOS: La mayoría de pacientes fueron varones (60,3%), con diagnósticos de hematuria, RAO y patología genital. Las mujeres, presentaron pielonefritis, ITU y dolor lumbar de manera más frecuente. Los varones ingresaron en mayor proporción. La edad, el diagnóstico de infección/sepsis o dolor lumbar y un nivel MTS amarillo o naranja, resultaron ser factores independientes de ingreso. Tanto en el estudio univariable como multivariable, la edad mayor de 60 años (311 vs 220 min), los diagnósticos relacionados con ITU y sepsis (300 vs 250 min) y el ingreso hospitalario como resolución final (440 vs 240 min) influyeron de forma significativa en el tiempo de estancia en Urgencias. CONCLUSIONES: La edad > 60 años, el resultado de ingreso y el diagnóstico de infección/sepsis fueron factores independientes de mayor tiempo en Urgencias. La presencia de dolor persistente y de infección/sepsis se comportaron como factores independientes de ingreso.

RESUMO

BACKGROUND: Management of active surveillance (AS) in low-risk prostate cancer (PCa) patients could be improved with new biomarkers, such as the 4Kscore test. We analyze its ability to predict tumor reclassification by upgrading at the confirmatory biopsy at 6 months. METHODS: Observational, prospective, blinded, and non-randomized study, within the Spanish National Registry on AS (AEU/PIEM/2014/0001; NCT02865330) with 181 patients included after initial Bx and inclusion criteria: PSA ≤10 ng/mL, cT1c-T2a, Grade group 1, ≤2 cores, and ≤5 mm/50% length core involved. Central pathological review of initial and confirmatory Bx was performed on all biopsy specimens. Plasma was collected 6 months after initial Bx and just before confirmatory Bx to determine 4Kscore result. In order to predict reclassification defined as Grade group ≥2, we analyzed 4Kscore, percent free to total (%f/t) PSA ratio, prostate volume, PSA density, family history, body mass index, initial Bx, total cores, initial Bx positive cores, initial Bx % of positive cores, initial Bx maximum cancer core length and initial Bx cancer % involvement. Wilcoxon rank-sum test, non-parametric trend test or Fisher's exact test, as appropriate established differences between groups of reclassification. RESULTS: A total of 137 patients met inclusion criteria. Eighteen patients (13.1%) were reclassified at confirmatory Bx. The %f/t PSA ratio and 4Kscore showed differences between the groups of reclassification (Yes/No). Using 7.5% as cutoff for the 4Kscore, we found a sensitivity of 89% and a specificity of 29%, with no reclassifications to Grade group 3 for patients with 4Kscore below 7.5% and 2 (6%) missed Grade group 2 reclassified patients. Using this threshold value there is a biopsy reduction of 27%. Additionally, 4Kscore was also associated with changes in tumor volume. CONCLUSIONS: Our preliminary findings suggest that the 4Kscore may be a useful tool in the decision-making process to perform a confirmatory Bx in active surveillance management.

RESUMO

OBJECTIVES: To review the pathological criteria used to select patients for active surveillance, the optimization of biopsies and the role of confirmatory biopsy and of the transperineal approach. METHODS: A bibliographic revision of the last years about active surveillance in prostate cancer as well as prostate biopsy, optimal rebiopsy protocols and transperineal approach has been carried out. RESULTS: Misclassification of insignificant disease based on pathological criteria of the first standard biopsy range from 20% to 30% of men. It is likely that many patients who ultimately progress on active surveillance had at the time of diagnosis more advanced disease that was missed by transrectal ultrasound (TRUS) biopsy. This is the main cause of progression on initial follow-up biopsy within 1 year of starting active surveillance. Although the role of immediate prostate rebiopsy after the diagnosis of low-risk prostate cancer and has not been well described, repeat biopsy before the initiation of AS performed shortly after diagnosis (6 months) identifies most patients who harbor high grade or more extensive cancers that may not be appropriate for a surveillance strategy. CONCLUSIONS: PSA, PSAD, and number of cores at initial diagnosis are not helpful in predicting misclassification of AS eligibility. The role of MRI for AS remains unclear and the technique of MRI/US fusion biopsy still lacks consensus on a standardized procedure. Patients considering active surveillance should undergo immediate confirmatory biopsy within 6 months to decrease the risk of substantially underestimating cancer size and grade, even in patients with strict criteria in the initial biopsy and subsequently, to better assess the risk of progression. In this way, most protocols of AS recommend performing volume-based biopsies in the confirmatory procedure. Perhaps, an extensive transperineal template-guided mapping biopsy (TTMB) procedure could more accurately identify those men with occult significant disease. Due to confirmatory biopsy identifies a patient group that is unlikely to progress during the first 5 to 10 years of AS the need of intensive biopsy schedule during follow-up of patients undergoing active surveillance might be reduced.

RESUMO

OBJETIVO: Revisar los criterios patológicos utilizados para seleccionar a los pacientes para vigilancia activa en cáncer de próstata, la optimización de las biopsias y el papel de la biopsia confirmatoria y del abordaje transperineal. MÉTODOS: Se ha realizado una revisión bibliográfica de los últimos años sobre la vigilancia activa en cáncer de próstata, así como de la optimización de la biopsia próstata, los protocolos de rebiopsia y de la técnica transperineal en vigilancia activa. RESULTADOS: La clasificación inadecuada como tumor prostático insignificante basada en criterios patológicos de la biopsia inicial estándar se produce en el 20% al 30% de los hombres. Es probable que muchos pacientes en programas de vigilancia activa (VA) que progresan ya presentaban en el momento del diagnóstico una enfermedad más avanzada, no detectada por la biopsia transrectal (TRUS). Esta es la principal causa de progresión en las primeras biopsias de seguimiento en el primer año de un programa de vigilancia activa. Aunque el papel de rebiopsia de próstata inmediata tras el diagnóstico de cáncer de próstata de bajo riesgo no ha sido bien descrita, la repetición de la misma antes de la iniciación del programa de VA, realizada poco después de diagnóstico (6 meses), identifica la mayoría de los pacientes que albergan cánceres más extensos o de alto grado y que no resultan apropiados para una estrategia de vigilancia activa. CONCLUSIONES: La realización de un PSA, PSAD o el número de muestras en la biopsia inicial no son parámetros útiles en la predicción de un error en la clasificación patológica de un tumor como insignificante con vistas a la inclusión en un programa de VA. El papel de resonancia magnética (RM) permanece confuso y la técnica de la resonancia magnética / biopsia de fusión aún carece de consenso como un procedimiento estandarizado. Los pacientes en los que se considere la inclusión en VA deben someterse a una biopsia confirmatoria inmediata dentro de los 6 meses posteriores para disminuir el riesgo de subestimar el grado y tamaño del tumor, incluso en aquellos pacientes con criterios estrictos en la biopsia inicial, pudiendo además evaluar mejor el riesgo de progresión. La mayoría de los protocolos recomiendan tomar un número de cilindros basándose en el volumen prostático durante el procedimiento de confirmación. Tal vez un procedimiento de biopsia transperineal guiada mediante plantilla podría identificar con mayor precisión esos casos con enfermedad significativa oculta, sobre todo en la zona anterior de la glándula. Además dado que la biopsia confirmatoria identifica un grupo de pacientes en los que es poco probable la progresión durante los primeros 5 a 10 años, podría reducirse la necesidad de un protocolo intensivo de biopsias durante el seguimiento de pacientes sometidos a vigilancia activa

RESUMO

Fundamento: la única forma de contraer el virus de inmunodeficiencia humana durante el tratamiento estomatológico es a través del contacto de la sangre de un paciente seropositivo con la piel o mucosa no intacta del profesional, lo cual demanda medidas de bioseguridad para reducir el riesgo de infección cruzada así como el cumplimiento de aspectos bioéticos a tener en cuenta en la asistencia a dichos pacientes. Objetivo: determinar el nivel de conocimientos de estomatólogos sobre bioseguridad y el principio bioético de justicia en el tratamiento a pacientes con virus de inmunodeficiencia humana. Métodos: estudio descriptivo de corte transversal que incluyó a 45 profesionales que laboraron en consultorios estomatológicos de tres parroquias en Caracas, Venezuela, durante enero a diciembre de 2010. Se analizó: conocimientos sobre bioseguridad (mecanismos de transmisión de la enfermedad, medidas de control, flujograma de esterilización, medidas ante un accidente de trabajo) y sobre el principio bioético justicia (momento y lugar de tratamiento, instrumental a utilizar, tiempo a dedicar al paciente). Resultados: se obtuvo como nivel de conocimiento sobre el principio bioético de justicia: bueno el 40 %, regular el 37,7 % y malo el 22,2 %. En relación con las medidas de bioseguridad: bueno el 26,6 %, regular el 24,4 % y malo el 48,8 %. Conclusiones: el nivel de conocimientos sobre el principio bioético de justicia y sobre las medidas de bioseguridad para tratar a pacientes que viven con virus de inmunodeficiencia humana es insatisfactorio en más de la mitad de los estomatólogos encuestados.


Background: the only way of contracting human immunodeficiency virus during dental treatment is through contact with the blood of an HIV-positive patient with non-intact skin or mucosa of the professional. This requires biosecurity measures to reduce the risk of crossed infection and ensure compliance of bioethical aspects to be considered when treating these patients. Objective: To determine knowledge levels of dentists on biosafety and bioethical principle of justice in the treatment of patients with human immunodeficiency virus. Methods: A cross sectional and descriptive study was conducted involving 45 professionals who worked in Stomatological clinics of three parishes in Caracas, Venezuela, from January to December 2010. The following were analyzed: knowledge on biosafety (mechanisms of disease transmission, control measures and flowchart sterilization measures before an accident) and the justice bioethical principle (time and place of treatment, instruments used and time to devote to patient). Results: The knowledge level according to the bioethical principle of justice was assessed: 40% for good, 37.7% for average and 22.2% for bad. For biosecurity measures it was obtained: 26.6% good, 24.4% average and 48.8% bad. Conclusions: knowledge level on the bioethical principle of justice and biosecurity measures to treat patients living with human immunodeficiency virus is unsatisfactory in more than half of the dentists surveyed.

RESUMO

Introducción: Evaluamos, en cuanto a recurrencia, los factores pronósticos en el cáncer vesical no infiltrante de músculo y el efecto de la terapia intravesical. Material y métodos: Estudiamos 419 neoplasias vesicales. Realizamos análisis univariados y multivariados sobre 24 variables de estas neoplasias y valoramos distintos tratamientos. Resultados: Existieron diferencias significativas en el tiempo libre hasta la recurrencia, que fue menor en los tumores que recurrieron en menos de 12 meses, en los tumores múltiples (3 o más tumores) y de cúpula; además existieron diferencias estadísticamente significativas cuando se estudiaron dos grupos homogéneos de cirujanos.El empleo de instilaciones vesicales incrementó de forma independiente el tiempo hasta la recidiva. Se demostró que la recurrencia se produjo significativamente más tarde cuando se habían empleado dosis altas de BCG y terapia de mantenimiento. Conclusiones: Los siguientes factores resultaron independientes para explicar menor tiempo libre hasta la recurrencia superficial: recidiva en el primer año, multiplicidad, técnica quirúrgica, no empleo de lavados intravesicales, tratamiento con dosis bajas de BCG y terapia de inducción frente a mantenimiento. El empleo de instilaciones vesicales, con dosis altas de BCG y terapia de mantenimiento, incrementó de forma independiente el tiempo hasta la recidiva.

RESUMO

BACKGROUND AND OBJECTIVE: The aim of this study was to analyze the significance of anemia as well as other prognostic factors influencing survival in patients with renal cell carcinoma (RCC). PATIENTS AND METHODS: A retrospective review of data of 316 patients who underwent surgery between 1970 and 2003 was performed. Most important known prognostic factors of RCC were investigated. RESULTS: Most of patients had T1b-T2, low nuclear grade and single tumours. In 8.2% and 9% of cases, lymph node and metastatic dissemination were detected at the time of diagnosis, respectively. At the beginning, most frequent symptoms were hematuria and pain, with anemia (Hb >10g/dl) in 69 patients. After a median follow-up of 50 months, 24.1% of patients had a recurrence. From these, more than 50% developed recurrence within one year after nephrectomy. Advanced tumours (T3-4) consisted of high nuclear grade (III-IV) tumours, larger size tumours, with necrosis and vascular infiltration in surgical specimen, as well as lymph node and metastatic dissemination. In multivariate analysis, anemia, time to recurrence, type of treatment for recurrence as well as lymph node dissemination were independent factors of cancer specific survival. CONCLUSION: Anemia seems to be a marker of recurrence and progression in patients with renal cell carcinoma undergoing nephrectomy. From our point of view, anemia could be considered a significantly high mortality rate for renal cancer in these patients.

RESUMO

OBJETIVOS: La tendencia a la diseminación del cáncer de próstata es sobre todo a los ganglios linfáticos regionales y hueso, y en una menor proporción a pulmón, hígado y cerebro. El hallazgo de metástasis en otras localizaciones es un hecho excepcional.El objetivo de este trabajo es revisar la frecuencia y características clínicas de las metástasis de adenocarcinoma de próstata en el tejido celular subcutáneo.MÉTODOS: Presentamos el caso de un varón de 71 años que se diagnosticó de un adenocarcinoma de próstata. Se realiza prostatectomía radical y colocación de esfínter artificial por incontinencia urinaria de esfuerzo.RESULTADOS: Durante el seguimiento evoluciona con progresion bioquímica, recidiva local y metástasis óseas, es diagnosticado de metástasis en tejido subcutáneo perirreservorio de esfínter artificial.CONCLUSIONES: El cáncer de próstata es una enfermedad muy prevalerte en nuestro medio, en la cuál el hallazgo clínico de metástasis en órganos distintos al hueso o ganglios linfáticos regionales, se sigue de un corto periodo de supervivencia. El diagnóstico de metástasis en el tejido subcutáneo es un hecho que tal vez estar infradiagnosticado debido su curso clínico indolente y que podría además no elevar las cifras de PSA, en cualquier caso es un dato de mal pronóstico(AU)


OBJECTIVES: Prostate cancer tends to spread to regional lymph nodes and bone, and, to a lesser degree, to lung, liver, and brain. Metastases in other locations are exceptional.To review the frequency and clinical characteristics of metastasis to subcutaneous cellular tissue in adenocarcinoma of the prostate.METHODS: The case of a 71-year-old man diagnosed of adenocarcinoma of the prostate is reported. The patient underwent radical prostatectomy and artificial sphincter for stress urinary incontinence.RESULTS: During follow-up the patient showed biochemical progression, local recurrence, and bone metastasis. The disease metastasized in the subcutaneous tissue around the reservoir of the artificial sphincter.CONCLUSIONS: Prostate cancer is highly prevalent in our part of the world. The clinical finding of metastasis in organs other than bone or regional lymph nodes is accompanied by a short survival. Metastases in subcutaneous tissue may be underdiagnosed due to its indolent clinical course and possible absence of PSA elevation. In any case, subcutaneous metastases have an unfavorable prognosis(AU)

RESUMO

Fundamento y objetivo: Valorar el significado pronóstico de la anemia para el carcinoma de células renales (CCR), así como otros factores implicados en la supervivencia. Pacientes y método: Se realizó un análisis retrospectivo de los datos de 316 pacientes con carcinoma renal intervenidos entre los años 1970 y 2003. Se investigaron las principales características implicadas en el pronóstico de pacientes con CCR. Resultados: La mayoría de los tumores presentaron estadios bajos T1b-T2, con grados nucleares bajos (I–II) y un tumor único. En un 8,2% se encontró afectación ganglionar en el momento del diagnóstico y en casi un 9% existían metástasis a distancia. La clínica más frecuente al inicio fue hematuria o dolor, y la anemia (hemoglobina<10g/dl) estuvo presente en 69 casos Resultados: Con una mediana de seguimiento de 50 meses, recidivó un 24,1% de casos, de los que más del 50% ocurrió en el primer año tras la intervención. Los tumores avanzados (T3-4) tendieron a presentar un grado nuclear mayor (III–IV), más tamaño, necrosis, afectación vascular y ganglionar, asociándose más frecuentemente a metástasis a distancia. Los factores que influyeron de forma independiente en la mortalidad específica por cáncer fueron la presencia de adenopatías metastásicas, el tiempo libre de enfermedad en los casos con recidiva, así como el tratamiento de esa recidiva y la presencia de anemia. Conclusión: La existencia de anemia en pacientes intervenidos por carcinoma renal puede ser un marcador de recidiva y progresión de la enfermedad que implica, finalmente, un mayor riesgo de mortalidad por este tumor (AU)


Background and Objective: The aim of this study was to analyze the significance of anemia as well as other prognostic factors influencing survival in patients with renal cell carcinoma (RCC). Patients and methods: A retrospective review of data of 316 patients who underwent surgery between 1970 and 2003 was performed. Most important known prognostic factors of RCC were investigated. Results: Most of patients had T1b-T2, low nuclear grade and single tumours. In 8.2% and 9% of cases, lymph node and metastatic dissemination were detected at the time of diagnosis, respectively. At the beginning, most frequent symptoms were hematuria and pain, with anemia (Hb >10g/dl) in 69 patients. Results: After a median follow-up of 50 months, 24.1% of patients had a recurrence. From these, more than 50% developed recurrence within one year after nephrectomy. Advanced tumours (T3-4) consisted of high nuclear grade (III–IV) tumours, larger size tumours, with necrosis and vascular infiltration in surgical specimen, as well as lymph node and metastatic dissemination. In multivariate analysis, anemia, time to recurrence, type of treatment for recurrence as well as lymph node dissemination were independent factors of cancer specific survival. Conclusion: Anemia seems to be a marker of recurrence and progression in patients with renal cell carcinoma undergoing nephrectomy. From our point of view, anemia could be considered a significantly high mortality rate for renal cancer in these patients (AU)

RESUMO

OBJECTIVE: We report one case of gonadal stromal testicular tumor and perform a bibliographic review. METHODS/RESULTS: We present the case of a 42 year-old male patient consulting for a painless right testicular mass. Orchiectomy was performed and the patient underwent follow-up. CONCLUSIONS: Nonspecific sexual cord tumors are extremely rare, with slow growing and benign behaviour, presenting positive staining for various markers.

RESUMO

OBJECTIVE: We report one case of ovarian metastasis secondary to a renal clear cell carcinoma. METHODS/RESULTS: 52 year-old consulting for metrorrhagia with the initial diagnosis of primary ovarian carcinoma. Tumor dissemination work up tests reported a renal mass suggestive of ovarian metastasis. Surgery included hysterectomy, double annexectomy, and radical nephrectomy. Final diagnosis was renal clear cell carcinoma with ovarian metastasis. CONCLUSIONS: Metastases to the ovary pose a diagnostic problem in their interpretation, especially when they show a similar histology to the primary ovarian tumor. Due to therapeutic and prognostic implications, it is very important to differentiate if it is a primary ovarian tumor or a metastasis from a renal carcinoma.
