RESUMO

Introducción: En 2007 en España el 43% de los donantes tuvo más de 60 años, lo que supone peor calidad del injerto y probablemente peor supervivencia. Objetivo: Nuestro objetivo es analizar la influencia de la edad del donante en la supervivencia del injerto. Material y métodos: Analizamos retrospectivamente 216 trasplantes renales consecutivos realizados entre 2000–2008. Valoramos la influencia de la edad del donante sobre la supervivencia del injerto y buscamos el mejor punto de corte. Para el estudio de la supervivencia actuarial del injerto se ha utilizado el método de Kaplan Meyer. Para la comparación de curvas de supervivencia utilizamos el test de log-rank. Para el estudio de los factores influyentes en la supervivencia hemos utilizado los modelos de regresión de Cox en forma de estudio univariado y multivariado. Resultados: La media de seguimiento fue de 48 meses (±33,4 DE) y la mediana de seguimiento fue de 48 meses (rango de 0–166 meses).El análisis univariado de la supervivencia del injerto nos mostró que la edad del donante como variable continua influye significativamente en la supervivencia del injerto (odds ratio: 1,03; 95% intervalo de confianza [IC]: 1,01–1,05; p=0,009).Al estudiar la relación entre la edad del donante y el receptor evidenciamos una correlación inversa significativa (correlación de Pearson: 0,55; p<0,0001), pero a pesar de esto, la significación se mantiene si se ajusta con la edad de los receptores (odds ratio: 1,02; 95% IC: 1,01–1,04) (p=0,04). El mejor punto de corte corresponde a 60 años. La supervivencia actuarial del injerto en donantes mayores de 60 años es del 79 (95% IC: 74–84) y del 71% (95% IC: 65–77) en 3 y 5 años frente al 94 (95% IC: 94–96%) y al 90% (95% IC: 88–92) en los receptores de riñones de donantes menores de 60 años (p=0,002).El estudio multivariado de los factores influyentes en la supervivencia del injerto revela que la edad del donante dicotomizada en mayor y menor de 60 años, la presencia de reintervenciones quirúrgicas inmediatas y la función diferida eran los factores de influencia independiente en la supervivencia del injerto. Conclusiones: La edad del donante mayor de 60 años influye negativamente en la supervivencia del injerto renal con valor pronóstico independiente (AU)


Introduction: In 2007 in Spain 43% of donors were older than 60 years. This produces a worse graft quality and probably a worse survival. Objective: Our objective is to analyze the influence of donor age on graft survival. Material and methods: We analyze retrospectively 216 renal consecutive transplants realized between 2000 and 2008. A univaried and multivaried study (Cox regression) was performed and Kaplan-Meyer test with log rank for graft survival. Results: Follow-up mean of 40 months (±33,4 SD). The univaried analysis of graft survival showed that donor age had a significative influence on graft survival. (OR=1,03; 95% CI 1,01–1,05) (p: 0,009). Studying the relation between donor and recipient age we find an inverse correlation (Pearson's Correlation: 0,55. p<0,0001), but there are significative differences after the adjustment for recipient age. (OR: 1,02; 95% CI 1,01–1,04) (p: 0,04). Optimal cut-point value determined by the ROC analysis was 60 years. The graft survival of donors over 60 years is 79% (95% CI; 74–84%) and 71%(95% CI; 65–77%) at 3 and 5 years in contrast with 94% (95% CI; 94–96%) and 90% (95% CI; 88–92 in donors under 60. (p: 0,002). The multivaried study of the influential factors on graft survival reveals that donor age dichotomized in older or younger than 60, the presence of a surgical immediate reintervention and a delayed graft function were independent influence factors. Conclusions: Donor age over 60 years has a negative and independent prognostic influence on graft survival (AU)

RESUMO

OBJECTIVES: To analyze surgical complications in kidney transplantation and their influence on graft survival. MATERIALS AND METHODS: A retrospective analysis was made of the early and late surgical complications occurring in 216 consecutive kidney transplants performed at our institution and their influence on graft survival. RESULTS: At least one surgical complication occurred in 82 (38%) of the 216 transplantations, and 68 (31%) required some type of repeat surgery, 23 in the early postoperative period and 45 more than 3 months after surgery. Mean follow-up was 48 months (SD +/-33.4), and median follow-up 48 months (range, 0-166 months). No recipient or donor factors predisposing to surgical complications were found. Graft survival was significantly shorter in patients with surgical complications [3- and 5-year survival rates of 86% (95% CI 83-89) and 78% (95% CI 73-82) as compared to 92% (95% CI 90-94) and 88% (95% CI 85-91), p=0.004]. Early repeat surgery, venous thrombosis, and wound infection were among the complications having an independent influence on graft survival. A multivariate analysis of graft survival in the whole group showed early repeat surgery to be a factor with an independent prognostic value (OR: 4.7; 95% CI 2.2-10, p<0.0001). Delayed function and donor age older than 60 years were the other independent influential factors. CONCLUSION Surgical complications have an influence on graft survival. The need for early repeat surgery, delayed function, and donor age older than 60 years are independent predictors of graft survival.

RESUMO

The role and the potential benefit, if any, of pelvic lymphadenectomy in prostate cancer are still controversially discussed. It is generally accepted that PLND at time of radical prostatectomy is the only reliable diagnostic procedure to achieve as much individual histological staging information as possible to trigger postoperative adjuvant management. However, the extent of pelvic lymph node dissection (limited vs. extended) and the most suitable candidates for this procedure are still a matter of intense debate. The aim of this review is to critically evaluate the current status on lymph node dissection in prostate cancer.

RESUMO

OBJECTIVE: Hereby, we analyze the characteristics of the clinical Gleason 8-10 group of patients with in our series diagnosed of Prostate Cancer and treated by means of radical prostatectomy, and we try to ascertain which are the influence factors within this group upon progression and progression free survival. MATERIAL AND METHODS: From the global series of 781 patients with T1-T2 prostate cancer treated by means of radical prostatectomy between 1990 and 2004, we study 108 with a Gleason score on the biopsy of 8-10. Median PSA was 12 ng/ml and 50% were T2. Variables related to biochemical progression and progression free survival have been studied, comparing the group of Gleason 8-10 with the rest and analyzing, within the Gleason 8-10 group which are the related variables with progression and progression free survival, trying to find a predictive model. Contingency tables and logistic regression have been employed. For the survival analysis, Kaplan Meyer curves, log-rank and Cox models. RESULTS: Actual State: 62.7% (490/781) are alive and free of biochemical progression, 24.8% (194/781) are alive with biochemical progression, 2.9% (23/781) are dead by cancer and 1.9% (15/781) are dead by other cause and 7.6% (59/781) are lost. Biochemical progression study of the whole series (781 patients) Clinical Gleason score 8-10 is a influence factor on the univariate study (OR2,61 IC 95%: 1.7-4). In the progression free survival study (PFS) of the whole series (781 patients) the PFS in Clinical Gleason 8-10 at 3 and 5 years is 56 +/- 5% y 35 +/- 7%, significantly worse than the rest of the group (p < 0.0001). In the multivariate study of the influence factors on the PFS includes Clinical Gleason Score 8-10 as an independent prognostic factor (OR: 2.6 IC 95%: 1.6-4.12) p = 0.003, together with the clinical stage (OR: 1.,81 IC 95%: 1.18-2.78) p < 0.006, the PSA (OR: 1.03 IC 95%: 1.025-1.046) p < 0.0001 and the side of tumor on the biopsy (OR: 1.5 IC 95%: 1.01-2.24) p = 0.045. In the clinical Gleason score 8-10 group the influent factors on the PFS are. PSA (OR: 1.02 IC 95%: 1.003-1.04) and pathological stage (OR: 3.84 IC 95%: 1.77-8.27). Patients with a pT2 have a significantly better survival than those pT3 at 3 and 5 years (80 +/- 6%; 54 +/- 13% y 40 +/- 7%; 27 +/- 7%) (p < 0.0001). The best cut point for the PSA is 11 ng/ml. Patients with a PSA < 11 ng/ml have a 3 and 5 years survival better than those with >11 ng/ml PSA (74 +/- 7%, 30 +/- 22% y 40 +/- 7%, 26 +/- 7%) (p < 0.0001). CONCLUSIONS: Clinical Gleason Score 8-10 is a negative independent prognostic factor on the progression free survival, but its prognosis is better if they present a PSA prior surgery lower than 11 ng/ml and the pathological stage is a pT2.

RESUMO

OBJECTIVE: We present our 20 years experience treating patients with vena cava extension in whom an extracorporeal circulation, hypothermia, cardio circulatory arrest (ECC-H-CCA) in order to perform, together with a tumoral resection, a thrombus resection. MATERIAL AND METHODS: From 1985 to 2005 a total of 28 retroperitoneal tumor were treated: 25 renal cancers, a Wilms tumor, a paratesticular rabdomiosarcoma, and a pheocromocitoma. All of them had an extension by means of thrombus above the suprahepatics veins. All of them were treated by means of ECC-H-CCA for thrombus extraction. A descriptive study of the serie is performed as well as a Kaplan Meyer survival study. RESULTS: Surgical complications were present within 10 patients (35%), with a surgical mortality of two patients (7%): one intra-operatively because a massive embolism of the lungs and the other because of a lung embolism on the 4th post-operative day. Global actuarial survival was 29.1+/-10% at three years and 17.5+/-8% at five years. Analyzing only who do not have metastatic lesions, nor lymph nodes at diagnosis their three year survival was 50.9+/-16.3% and 32.2+/-16% at five years. Mean while those who have any metastatic lesion at diagnosis their three and five years survival was 20.8+/-12% and 10.4+/-9% respectively. CONCLUSIONS: The employ of surgical techniques with ECC-H-CCA with in oncological pathology associated with vena cava thrombus is justified and its employment does not worsen the survival; it is indicated because its results, allowing a complete tumoral resection in a safe and reproducible fashion.

RESUMO

Introducción: El receptor de esteroides y xenobióticos SXR se ha demostrado su activación por parte de numerosos medicamentos, incluidos potentes inductores del citocromo P450, como la rifampicina y el cotrimazol. La función del SXR es bien conocida, y consiste en regular de manera positiva la trascripción del citocromo P450 3A4 (CYP3A4) y el gen de multirresistencia a drogas (multidrug resistance gene) MDR1, se considera una llave clave en el mecanismo regulador del metabolismo de los xenobióticos encontrándose involucrado en todas las fases de detoxificación Múltiples enzimas involucradas en el metabolismo y la degradación de hidrocarburos policíclicos aromáticos (PAH) son polimórficas en humanos, incluyendo la glutation S-transferasa (GSTs), N-acetiltransferasa (NATs), sulfotransferas (SULTs)1A1 y el citocromo p450 (CYP)1B1. Objetivos: Los objetivos que nos hemos planteado son los siguientes: 1. Analizar la expresión del factor de trascripción SXR y del MDR1 en vejiga mediante RT-PCR en tiempo real, tanto en vejiga tumoral como vejiga normal. 2. Analizar la relación de los factores clínicos y patológicos con la expresión del SXR y del MDR1. 3. Analizar la expresión de los polimorfismos de CYP1B1, GSTM1 GSTT1 y SULT1A1, y su correlación con distintos factores clínico patológicos y moleculares. Material y Métodos: De manera prospectiva se calculó un tamaño muestral necesario para este estudio. Se incluyeron 67 pacientes de dos instituciones distintas (Hospital Universitario Miguel Servet (49 HUMS) y Clínica Universitaria de Navarra (18 CUN)), diagnosticados de cáncer vesical infiltrante y tratados mediante cistectomía radical, se le realizó la determinación de la expresión de SXR y MDR1 mediante PCR cuantitativa en tiempo real, así como de los polimorfismos CYP1B1, GSTM1 GSTT1 y SULT1A1 mediante RFLP (restricción de la longitud del fragmento del polimorfismo). Se correlaciona mediante tablas de contingencia la correlación con el resto de los factores pronósticos. Resultados: La media de seguimiento de los pacientes fue de 23,7 meses, con una mediana de 28,26 meses. De los 67 pacientes estudiados, 31 pacientes (46,3%) presentaron progresión de la enfermedad, bien en forma de recidiva local, metástasis a distancia o ambos, con un tiempo medio a recidiva de 12,4 meses, mediana de 10 meses, con un rango de 1,1 mes a 31,9 meses. 36 pacientes (53,7%) no presentaron evidencia de progresión de la enfermedad. El receptor de esteroides y xenobióticos SXR así como el gen de multirresistenia a drogas (Multidrug resistance gene (MDR1)), se expresan en vejiga normal (0,94ΔCt y 0,94ΔCt) y en vejiga tumoral de la pieza de cistectomía (1,09 ΔCt y 0,45 ΔCt). Hemos analizado su expresión de manera cuantitativa y de manera cualitativa. La expresión de SXR se correlaciona con la presencia de carcinoma in situ (p=0,024), infiltración vasculo-linfática (p=0,05) mientras que MDR1 se correlaciona con la presencia de infiltración vasculo linfática (p=0,05) A su vez ambos la presencia de ambos factores se correlaciona entre ellos (p=0,011) Los polimorfismos: CYP1B1, GSTM1, GSTT1 y SULT1A1, se expresan en vejiga pero su expresión no guarda correlación con ningún factor pronóstico Conclusiones: El SXR y el MDR1 se expresan tanto en vejiga normal y tumoral. Y que dicha expresión guarda una correlación con factores pronósticos con influencia en la supervivencia descritas en la literatura


Introduction: Steroid and Xenobiotic Receptor (SXR) has demonstrated its activation by numerous drugs, including cytochrome P450 potent inducers like rifampicina or cotrimazol. The role of SXR is well known, and lies regulating in a positive manner cytochrome P450 3A4 (CYP3A4) transcription and the multidrug resistance gene (MDR1), it’s considered a key in the xenobiotic detoxification mechanism, being involved in all phases of the detoxification process. Enzymes involved in Policyclic Aromatic hidrocarbures (PAH) metabolism and degradation are polymorphic in humans, including glutation S-transferases (GSTs), N-acetiltransferases (NATs), sulfotransferases (SULTs)1A1 and cytochrome p450 (CYP)1B1. Objectives: The objectives we’ve planned are: 1. Analyze the expression of the transcription factor SXR and MDR1 in bladder by means of RT-PCR real time, both in normal bladder and in tumoral bladder. 2. Analyze the relation between clinical and pathological factors with the expression of SXR and MDR1. 3. Analyze the expression of the polymorphims CYP1B1, GSTM1 GSTT1 and SULT1A1 and their correlation with different clinic-pathological and molecular factors. Material and Methods: In a prospective way the size of the sample was estimated. In 67 patients from two institutions (Hospital Universitario Miguel Servet (49 HUMS) and Clinica Universitaria de Navarra (18 CUN)), diagnosed of invasive bladder cancer and treated by means of radical cystectomy, were determined the expression of both SXR and MDR1 by means of real time PCR, as well as the polymorphisms CYP1B1, GSTM1 GSTT1 y SULT1A1 by means of RFLP (Restriction fragment length polymorphism). Correlations with other prognostic factors by contingency tables were performed. Results: Average follow up was 23,7 months with a median of 28,26 months. Of the 67 patients studied, 31 patients (46,3) presented disease progression, in form of local recurrence or in distant metastasis or both. With a average time to progression of 12,4 months and a median of 10 months, with a range of 1,1 month to 31,9 month. 36 patients (53,7%) did not have any evidence of disease progression during follow up. The Steroid and Xenobiotic Receptor as well as the Multidrug Resistance Gene (MDR1) are expressed in both normal bladder (0,94ΔCt y 0,94ΔCt) and tumoral bladder in the cystectomy specimen(1,09 ΔCt y 0,45 ΔCt). We’ve analyzed their expression in a quantitative manner and in a qualitative manner. The expression of SXR correlates with the presence of ca. in situ (p=0,024), vasculo-lymphatic invasion (p=0,05) mean while MDR1 correlates with presence of vasculo-lymphatic invasion (p=0,05) Both factors are correlate between each others (p=0,011). Polymorphisms: CYP1B1, GSTM1, GSTT1 and SULT1A1, are expressed in these patients but their expression doesn’t correlates with any prognostic factor Conclusions: Both SXR and MDR1 are expressed in normal bladder as well as in tumoral bladder. And their expression correlates with different prognostic factors with influence in the survival described in the literature

RESUMO

Pheochromocytoma, a paraganglioma of suprarenal location, is a catecholamine-secreting chromaffin cell tumour. Spread of these tumours to the vena cava is rare and the thrombus only reaches the right atrium in exceptional cases. We present the case of a patient who, without previous symptomatology, presented with a clinical picture of multiorganic dysfunction with primary manifestation of a suprarenal tumour with vascular spread to the right atrium affecting the right suprahepatic vein.

RESUMO

El feocromocitoma, paraganglioma de localización suprarrenal, es un tumor cromafín secretor de catecolaminas. La extensión de éstos tumores a vena cava es rara y que el trombo alcance la aurícula derecha es excepcional. Presentamos el caso de una paciente que, sin clínica previa, presentó un cuadro de disfunción multiorgánica como primera manifestación de un tumor suprarrenal con extensión vascular hasta la aurícula derecha y afectación de la vena suprahepática derecha (AU)

RESUMO

OBJECTIVE: To study the clinical and pathological characteristics of incidental renal tumors treated in our center. MATERIAL AND METHODS: A retrospective review is conducted of 318 nephrectomies comparing the clinico-pathological variables of renal tumors diagnosed incidentally with those of symptomatic renal tumors. The factors influencing disease-free survival are analyzed in both groups. RESULTS: In our experience, although incidental renal tumors presented better survival than symptomatic ones owing to their better pathological state and tumor grade, incidental diagnosis was not an independent influencing factor in the multivariate study. Only when patients were studied who did not present metastases on diagnosis did incidental diagnosis become an influencing factor very close to statistical significance. CONCLUSIONS: Incidental diagnosis is not an independent prognostic factor.

RESUMO

Metastases in the kidney are rare, evenmore if primary source is thyroid. We report the tenth case of metastases in the kidney from thyroid, and it is the first to be follicular type and absolutely asymptom. Sonography and computerized tomography with suspicion of renal tumour are showed in a asymtom female 75 years old. Left partial nephrectomy was perfomed, initially it has been pathologically diagnosed as renal clear cells tumour, however the definitive pathologic report showed follicular tumour of thyroid. Local and systemic stage was discovered with complementary techniques. Sources of metastases in kidney and diagnoses techniques are discussed.

RESUMO

UNLABELLED: The aim of this study was to detect mutations in the human androgen receptor gene in radical prostatectomy specimens. MATERIAL AND METHODS: The genomic sequence was realized in 67 radical prostatectomy specimens. The mean age was 64 years old. The PSA median was 15 ng/ml. TNM 1997: 34.3% were T1 and 65.7% T2. Genomic sequence: 1. Radical prostatectomy specimens desparaffitation. 2. Extraction of the DNA 3. DNA amplification. 4. Automatic genome sequence. 5. Comparison with Gene-Bank. RESULTS: 16.7% of the specimens were mutated. The most frequent mutation was the punctual mutation. The exon most frequent mutated was exon 1.

RESUMO

Several classes of drugs have been investigated for their efficacy in treating overactive bladder syndrome (OAB) and stress urinary incontinence (SUI). Surgery and behavioral therapies are currently the mainstay of treating SUI. However, results are also being made available about a new oral medication, Duloxetine, which appears to be clinically safe and effective for the treatment of SUI. On the other hand, a new muscarinic receptor antagonist, Solifenacin, has been shown in clinical trials to be clinically effective, safe and well tolerated for treating OAB.

RESUMO

Prostate carcinoma is diagnosed in earlier phases of its evolution, but this carcinoma may have an unpredictible evolution. Radical treatment (surgery and radiotherapy) is the best treatment in clinically localized tumors. The biochemical failure over 5 years from the surgery is 20-50% of the patients; the biochemical failure over 10 years from the surgery is less frequent because of prognostic factors from the biologic nature of the tumor. We report a case with biochemical and clinical failure over 10 years from the surgery.

RESUMO

OBJECTIVES: To identify independent predictors of progression and global survival in patients affected by pT3 renal cell carcinoma. To make risk groups by risk factors. MATERIAL AND METHODS: We evaluated 117 patients with pT3 renal cell carcinoma. 88 was M0 and 29 M1. Most frequent clinical feature: asintomatic patients. 80 males (69%) and 37 females (31%). Mean age 59 (24-82). Median follow up 34 months (mean 44 +/- 39 months). RESULTS: Pathological stage (TNM 1997) was pT3a in 52 patients (43.6%), pT3b 63 patients (53.6%) and pT3c 2 patients. HISTOLOGY: clear cell carcinoma 106 patients (90.6%), papillary 5 patients (4.3%) an dchromophobe 4 patients (3.4%). Nuclear grading according Fuhrman's classification: G1 13 patients, G2 45 patients, G3 32 and G4 12 patients. Size > 4 cm (p = 0.005/p = 0.0019), grade 3-4 (p = 0.006/p = 0.0007), N+ (p = 0.034/p = 0.009) and M+ (p = 0.035/p = 0.042) were independent prognosis factors for progression and global survival of the pT3 renal cell carcinoma. Patients M0 with 0 or 1 risk factor have better global survival tanh patients M0 with 3 or 4 risk factors and patients M1. CONCLUSIONS: Size, grade, N+ and M+ were independent prognosis factors for progression and global survival of the pT3 renal cell carcinoma. Tera are no differencies in global survival between patients M0 with 2 or 3 risk factors and patients M1.

RESUMO

Primary tumors of extragonadal origin are rare, with fewer than 1000 cases described in the literature. Although the exact incidence of EGTs is unknown, clinical data suggest that roughly 3% to 5% of all germ cell tumors. We expose a case report of EGT with unusually clinic presentation. We present our diagnostic and therapeutic experience in this injuries.

RESUMO

Significant conceptual changes have taken place in renal tumoral diseases over the last few years. As a result of the authors' broad institutional experience, this overall revision describes the most up-to-date clinical and diagnostic aspects of this condition. Emphasis is made on molecular staging and two variables that guide the prognosis of the disease, a decisive feature to establish treatment and to contribute to change current survival rates.

RESUMO

The standard therapy for renal carcinoma is radical surgery. When dealing with single, under 4 cm tumors and in the case of renal tumors in single-kidney patients, the choice therapy is nephrectomy or partial nephrectomy. Response rates in metastatic renal carcinoma using the various immune therapy approaches available range from 15 to 35%, responses being short-lasting.
