[Response and progression-free survival in T2 to T4 bladder tumors treated with trimodality therapy with bladder preservation]. / Respuesta y supervivencia libre de progresión en tumores vesicales en estadios T2-T4 tratados con tratamiento trimodal de conservación vesical.

OBJECTIVE: To evaluate the response and the free-survival progression in patients diagnosed of invasive bladder cancer who have been treated with transurethral resection, chemotherapy and radiotherapy. This multimodal treatment is compared with a not random serie of patients treated by radical cistectomy. MATERIAL AND METHODS: Retrospective analysis of 43 cases of invasive bladder cancer treated with two schemes of bladder preservation between 1994-2007. They are compared with 145 cases treated with radical cistectomy in the same period of time. Pronostic variables included in the study are clinical stage, grade of differentiation, presence of ureteral obstruction, chemotherapy modality, radiotherapy doses and p53 and ki-67 expression. RESULTS: Mean and median time are 51 and 39 months in patients with multimodal treatment. Complete response is achieved in 72% of cases treated with bladder preservation. Ureteral obstruction is a prognostic factor (OR: 7,3;p:0,02). 72% patients with complete response mantain it at the end of the study. None of analyzed variables are predictors of maintenance of the response. Survival rates with a intact bladder were 69±7% and 61±7% at three and five years. Radiotherapy doses greater than 60Gy (OR: 6,1; p<0,001) and the absence of ureteral obstruction (OR: 7,5; p<0,002) were pronostic variables. Free-survival in patients with complete response was 80±7% and 58±10% at three and five years. At the end of the study, 53,5% of patients had a intact bladder and free-disease.In the same period of time, 145 radical cistectomies were performed due to muscle invasive bladder cancer. Mean and median time in this group were 29 and 18 months respectively. Stadistical analysis reveals a worse clinical stage in the group of patients treated with multimodal treatment (p:0.01). Free-survival was 72±5% and 63±7% at 3 and 5 years in the group of radical cistectomies. There was not statistical significant differences between cistectomies and bladder preservation. CONCLUSIONS: Patients treated with bladder preservation have a free-survival similar to those treated with radical cistectomy. Radiotherapy doses greater than 60Gy and absence of ureteral obstruction were free-survival prognostic variables.

[Surgical complications in kidney transplantation and their influence on graft survival]. / Complicaciones quirúrgicas en el trasplante renal y su influencia en la supervivencia del injerto.

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.

[Pelvic lymph node dissection (extended vs standard) and prostate cancer]. / Linfadenectomía (ampliada vs estándar) y cáncer de próstata.

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.

[Extracorporeal circulation and hypothermy surgery in tumors with vena cava extension: 20 years experience at the University Clinic of Navarra]. / Cirugía con circulación extracorpórea e hipotermia en tumores con extensión a vena cava: 20 años de experiencia de la clínica Universitaria de Navarra.

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.

[Polyarthritis secondary to intravesical BCG instillation, a case report]. / Poliartritis secundaria a instilaciones intravesicales de BCG, a propósito de un caso.

Immunotherapy with intravesical instillation of Bacillus Calmette is the best complementary after TUR treatment against T1 grade 2- 3 and CIS bladder cancer. However, this therapy is associated with several side- effects, incluiding joint symptoms. In this article we describe a case of polyarthritis associated with intravesical instillation, a rare complication. We review the clinical features, the pathogenic mechanisms and treatments described previously in the medical literature. Finally, we expose our brief experience and our final result.

[Evaluation and prognostic of cystic renal tumors]. / Valoración y pronóstico de los tumores renales quísticos.

OBJECTIVE: To evaluate the clinical and pathological characteristics of cystic renal tumors in our center. MATERIAL AND METHODS: A retrospective review of 239 nephrectomies is performed comparing the clinical and pathological variables of cystic tumors with those of solid renal tumors. Survival outcomes are analyzed in both groups. RESULTS: Our experience shows that cystic renal tumors behave like solid renal tumors, with no differences in survival shown. The variables studied show statistically significant differences in histological grade and number of tumors, with cystic tumors having a lower histological grade and being more often multiple in number. CONCLUSIONS: The behavior of cystic renal tumors is no different than that of solid renal tumors.

[Incidentally detected renal cancer. Prognostic factors]. / Tumores renales incidentales. Factores pronósticos.

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.

[Follicular carcinoma of the thyroid manifested initially as asymptomatic primary renal neoplasm]. / Masa renal asintomática como primera manifestación de carcinoma folicular de tiroides.

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.

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.

[Urinary incontinence surgery: TVT procedure]. / Tratamiento quirúrgico de la incontinencia: TVT.

The T.V.T. procedure has become a technique for Urinary incontinence and its different presentations. Many trials have reported the efficacy of this technique for different situations, as well as its results and complications. We review the literature and analyze the results and complications, comparing this technique with other such procedures.

[Urinary incontinence: new pharmacologic therapies]. / Nuevos fármacos en el tratamiento de la incontinencia urinaria.

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.

[Solitary lung metastasis after radical prostatectomy]. / Metástasis pulmonar solitaria tras prostatectomía radical.

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.

[Prognosis factors in pT3 renal carcinoma]. / Factores pronóstico en carcinoma renal pT3.

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.

[Usefulness of PET in the diagnosis and response to treatment of extragonadal germinal tumor with atypical presentation]. / Utilidad del PET en el diagnóstico y respuesta al tratamiento en un tumor germinal extragonadal de presentación atípica.

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.

[Clinical features, diagnosis, and prognosis of renal carcinoma]. / Clínica, diagnóstico y pronóstico del carcinoma renal.

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.

[Treatment of renal carcinoma]. / Tratamiento del carcinoma renal.

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.

[Prognostic value of P53, Ki67, and Rb protein in infiltrating bladder tumors]. / Valor pronóstico de la p53, Ki67 y la proteína Rb en los tumores vesicales infiltrantes.

OBJECTIVES: To determinate whether increased expression of the p53 and Ki67 and the of the tumour suppressor gene retinoblastoma (prot Rb), in an immunohistochemistry study, were associated with relapse in invasive bladder cancer. MATERIALS AND METHODS: 47 patients with invasive bladder cancer. 42 men and 5 women. Mean age 63 years old. Relapse in 19 patients (40%). Mean time until recurrence 8.5 months. p53 and Ki67 were study in 47 patients and prot Rb in 40 patients. RESULTS: p53: Mean expression 41%. There were significant differences in the increased expression of p53 between patients with and without relapse (p = 0.03). A statistically significant association was then observed between patients with p53 > 20% (vs p53 < 20%) and adverse outcome of the disease (p = 0.04). Ki67 and prot Rb: There were no significant differences in relapse and progression free survival between Ki67 > 40% (vs Ki67 < 40%) and prot Rb < 10% (vs prot Rb > 10%). p53 expression showed a statistically significant correlation with Ki67 and prot Rb. CONCLUSION: p53 is a good prognostic marker for the relapse and progression free survival in invasive bladder cancer.

[Primary bladder adenocarcinoma: our experience in the last 10 years]. / Adenocarcinoma vesical primario: nuestra experiencia en los últimos diez años.

Adenocarcinoma of the bladder is an uncommon neoplasm corresponding as usual to a metastases and with a lower frequency to a primary vesical tumour. We present the primary adenocarcinoma treated in our hospital in the last 10 years. The moment at the diagnosis is related to the prognosis because of its tendency to muscle infiltration. The most accepted treatment is the radical cistectomy and if recurrence occurs complementary proceedings must be consider.
