ABSTRACT

The Malignant Fibrous Histiocytoma is a very rare cancer and rather exceptional when located in bladder diverticulum. it occurs in men in their sixties, manifests itself through haematuria and/or irritative micturition. There is not a causal association. An immunohistochemical analysis is necessary to establish a differential diagnosis. It is aggressive, with a high rate of local recurrence and remote progression, thereby requiring early treatment that consists of radical cystectomy with pelvic lymph node dissection followed by adjuvant therapy, predominantly radiotherapy on the surgical wound. Close follow-up is crucially important. Poor survival rate even when patients undergo multimodal therapy.

ABSTRACT

A 35-year-old male patient was admitted to our hospital for urachal carcinoma with oligometastatic bone disease. He received a surgical resection through the umbilical area, urachal ligament and bladder dome (partial cystectomy) and adjuvant chemotherapy based on cisplatin-gemcitabine regimens together zoledronic acid with a good tolerance, no toxicity. Nine months after surgery, our patient presented no symptoms and the metastasis had been brought under control with no apparent signs of recurrence as assessed in a follow-up CT. To our knowledge, is the first case report of a urachal carcinoma with oligometastatic bone disease who received multimodal therapy, including surgery resection.

ABSTRACT

Chondroma is a benign tumour of mesenchymal origin that is composed of cartilage and rarely located in soft tissues, being described so far only in four cases, as located in the bladder, according to our knowledge. We describe the fifth case of a 67-year-old woman who consulted for microscopic haematuria, with an endoscopic finding of submucosal nodular image in the anterior wall of the bladder, which after resection and the histologic study shows cartilage and fibroconnective tissue, in part hyalinised, and positive immunohistochemical staining of cells with vimentin and S-100; this fact can support the diagnosis of bladder chondroma.

ABSTRACT

BACKGROUND/AIM: Biotin affects the genetic expression of several glucose metabolism enzymes, besides being a cofactor of carboxylases. To explore how extensively biotin affects the expression of carbon metabolism genes, we studied the effects of biotin starvation and replenishment in 3 distantly related eukaryotes: yeast Saccharomyces cerevisiae, nematode Caenorhabditis elegans and rat Rattus norvegicus. METHODS: Biotin starvation was produced in Wistar rats, in C. elegans N2 and S. cerevisiae W303A fed with abundant glucose. High-density oligonucleotide microarrays were used to find gene expression changes. Glucose consumption, lactate and ethanol were measured by conventional tests. RESULTS: In spite of abundant glucose provision, the expression of fatty oxidation and gluconeogenic genes was augmented, and the transcripts for glucose utilization and lipogenesis were diminished in biotin starvation. These results were associated with diminished glucose consumption and glycolysis products (lactate and ethanol in yeast), which was consistent across 3 very different eukaryotes. CONCLUSION: The results point toward a strongly selected role of biotin in the control of carbon metabolism, and in adaptations to variable availability of carbon, conceivably mediated by signal transduction including soluble guanylate cyclase, cGMP and a cGMP-dependent protein kinase (PKG) and/or biotin-dependent processes.

ABSTRACT

Objetivo: Presentar un caso de metástasis ovárica secundaria a un carcinoma de células claras renal. Método/Resultados: Mujer de 52 años que consultó por metrorragias siendo inicialmente diagnosticada de carcinoma primario de ovario. En los estudios de extensión se informa de masa renal sugestiva de metástasis ovárica. La intervención quirúrgica consistió en histerectomía con doble anexectomía y nefrectomía radical. El diagnóstico final fue de carcinoma de células claras renal con metástasis ovárica. Conclusión: Las metástasis tumorales en el ovario presentan un problema diagnóstico en su interpretación, especialmente cuando las metástasis presentan una histología similar al primario de ovario. Debido a las implicaciones terapéuticas y pronósticas es muy importante diferenciar si se trata de un tumor ovárico primario o un metástasis de un carcinoma renal (AU)


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 (AU)

ABSTRACT

Objetivos: Valorar el uso del ácido zoledrómico en el control del dolor de las metástasis óseas en el cáncer de próstata, así como estudiar su seguridad y efectos secundarios. Material y métodos: Se incluyeron en el estudio 37 pacientes consecutivos diagnosticados de cáncer de próstata con metástasis óseas entre los años 2005 y 2006 a los que se administró una dosis de 4 mg de Zometa(R) mensual durante una media de 10,24 meses, recogiéndose unos datos según un protocolo establecido. Resultados: En cuanto al control del dolor, observamos como en 8 de los 20 pacientes a los que se les administró Zometa(R), el control fue absoluto, en 6 de estos se consiguió un control parcialmente bueno (permitiendo una buena actividad diaria), en 4 el control fue parcialmente malo (empeorando su calidad de vida), mientras que 2 pacientes presentaron mal control del dolor. Respecto a los efectos adversos del Zometa(R), no observamos ningún efecto secundario en ninguno de nuestros pacientes ni durante la inyección del fármaco ni posteriormente, si bien en 2 pacientes se suspendió el tratamiento por su mal estado general. Conclusiones: El futuro de este tratamiento reside en saber si la administración precoz de este fármaco puede prevenir o retrasar la aparición de las metástasis, (merced a su actividad antitumoral demostrada), no sólo en las debidas al cáncer de próstata si no también a metástasis óseas secundarias a otros tumores genito-urinarios


Objectives: To probe the use of Zoledromic acid in the control of the pain due to bone methastasis of a prostate cancer. Material and method: We included in our study 37 consecutive patients diagnosed of prostate cancer who developed bone methastasis during 2005 and 2006 to whom we gave a 4 mg dose of Zoledromic acid during a mean time of 10.24 months. Results: We observed a complete control of the pain in 8 of the 20 patients, and partially in 6 of those patients. We did not evaluate any adverse reaction due to this treatment. Conclusions: We still yet to know whether the administration of this treatment in the early stages of the prostate cancer could prevent or retard the appearance of bone methastasis

ABSTRACT

Objetivos: Describir el patrón de presentación tanto clínico como anatomo-patológico de los pacientes diagnosticados de cáncer de próstata en nuestro servicio, comparando los datos obtenidos en el año 1995 y en el 2004. Material y métodos: Se revisaron las 216 historias clínicas de los pacientes diagnosticados en 1995 y 2004, recogiéndose unos datos según un protocolo establecido. Resultados: La edad media al diagnóstico fue significativamente más baja en el año 2004. En ese año, prevaleció el incremento de la concentración de PSA como causa de diagnóstico, seguido por los síntomas urinarios del tracto urinario inferior (STUI), mientras que en el año 1995 destacaron los STUI y el tacto rectal sospechoso. Se observó una mayor proporción de tumores de alto grado en el año 1995, donde los tumores predominantes fueron los de alto riesgo mientras que en el año 2004 fueron los de bajo riesgo y encontramos una mayor proporción de tumores de bajo grado. Conclusiones: La migración de la estadificación clínico patológica hacia estadios más precoces descrita tras el uso generalizado del PSA en pacientes asintomáticos, se confirmó en nuestro estudio, como demuestra la mayor proporción de tumores de alto grado con Gleason entre 8-10 ng/ml diagnosticados en la serie del año 1995 y un mayor número de tumores de bajo grado en el año 2004


Objectives: To describe the clinical and pathological factors of prostate adenocarcinomas diagnosed in our department in the years 1995 and 2004. Material and method: We review the 216 patients diagnosed in both years, recording several features. Results: The mean age was significatively lower in the year 2004. In that year, the increments of the PSA levels was the main reason for the diagnosis of the prostate cancer, followed by low urinary tract symptons (LUTS), while the LUTS was the main reason in 1995. There was a greater proportion of high grade tumors in 1995 and also in this year, high risk tumors were the most frequently found, while in 2004 low risk and low grade tumors were predominant. Conclusions: Due to the general determinations of PSA levels in asymptomatic patients in 2004, we found a greater proportion of high grade tumors in 1995 and lower grade tumors in 2004

ABSTRACT

Objetivos: Describir el patrón de diagnóstico y tratamiento en los pacientes diagnosticados de cáncer de próstata en nuestro servicio, comparando los datos obtenidos en el año 1995 y en el 2004. Material y métodos: Se revisaron las 216 historias clínicas de los pacientes diagnosticados en 1995 y 2004, recogiéndose unos datos según un protocolo establecido. Resultados: Se observaron diferencias significativas en las medias del número de cilindros obtenidos en las biopsias en el año 19952,3 frente a las del 20041,6. Respecto al tratamiento, en el año 1995 predominó la deprivación androgénica seguida de la prostatectomía radical mientras que en el año 2004 la terapia más utilizada fue la radioterapia (externa y/o braquiterapia), seguida por la deprivación androgénica y la prostatectomía radical. Resultaron factores independientes para plantear el tipo de tratamiento la edad (OR=5,6) y el grupo de riesgo (OR=2,8) en el año 2004 y únicamente la edad (>70 años vs <=70 años) en el año 1995. Conclusiones: La evolución experimentada en las distintas técnicas terapéuticas ha convertido al cáncer de próstata en una enfermedad multidisciplinar obteniendo una gran mejoría en los resultados del tratamiento. Pese a todo esto, el desconocimiento existente en la actualidad acerca de la historia natural del cáncer de próstata y de su evolución en la mayoría de los casos, hace que sea necesario la realización de grandes estudios prospectivos, los cuales se están llevando a cabo, para determinar si el cribado del cáncer de próstata mediante el uso del PSA puede ser útil o no


Objectives: To describe and compare the diagnostic and treatment factors of prostate adenocarcinomas diagnosed in our department in the years 1995 and 2004. Material and method: We review the 216 patients diagnosed in both years, recording several features. Results: Significant differences were found in the mean of cylinders taken in the biopsies, being higher in 20041,6 than in 19952,3. Hormonal deprivation was the predominant treatment in 1995 followed by radical prostatectomy, while in 2004 radiotherapy (external beam or braquitherapy) was the most frequent therapy used followed by hormonal deprivation and radical prostatectomy. Independent factors to apply the treatment was the age (OR=5,6) and the risk groups (OR=2,8) in the year 2004 and only the age (>70 years vs <=70) in the year 1995. Conclusions: The evolution held in treatment therapies for prostate adenocarcinomas, made this disease in terms of treatment a multidisciplinary disease obtaining better results
