En Bloc Resection of Right Renal Cell Carcinoma and Inferior Vena Cava Tumor Thrombus Without Caval Reconstruction: Is It Safe to Divide the Left Renal Vein?

Introduction: It has been suggested that inferior vena cava (IVC) reconstruction following resection of retroperitoneal tumors with IVC tumor thrombus (TT) is not required when adequate collateral circulation is present. There are no reports evaluating mid-term effects on renal function in these patients. The purpose of this study was to assess renal function after en bloc resection of right renal cell carcinoma (RCC) with obstructing IVC TT and the possible risks that may arise after left renal vein division. Materials and Methods: A bi-institutional retrospective review was performed over a 15-year period, assessing patients with right RCC and obstructing level II-IV TT. All patients underwent extensive evaluation and cardiology clearance, and informed consent was obtained for right radical nephrectomy and thrombectomy with or without IVC reconstruction with possible cardiopulmonary bypass (CPB). Patient demographics, tumor characteristics, intraoperative factors, complications, length of stay, and patient survival were evaluated. Preoperative creatinine was recorded, as was creatinine on the day of discharge and at 6 and 12 months postoperatively. Results: Twenty-two patients were included in the study. Median age at surgery was 62.5 (range: 45-79) years, and 19 (86%) of the patients were men. One patient (5%) had a level II thrombus, 14 patients (64%) had a level III thrombus (IIIa, n = 3; IIIb, n = 6; IIIc, n = 3; IIId, n = 2), and seven patients (32%) had a level IV thrombus. Intraoperatively, median estimated blood loss was 1.35 (range: 0.2-25) L. The median length of hospital stay was 11 (range: 5-50) days. Median preoperative creatinine was 1.20 (range: 0.40-2.70) mg/dl, and postoperatively, median creatinine was 1.3 (range: 0.86-2.20) mg/dl. Median creatinine levels at 6 months and 12 months postoperatively were 1.10 (range: 0.5-1.8) mg/dl and 1.40 (range: 0.6-2.0) mg/dl, respectively. Four patients died (range: 0.1-1.3 years), and median postoperative follow-up among the 18 ongoing survivors (at last follow-up) was 1.5 (range: 0.5-7.0) years. Conclusions: Resection of right RCC with an obstructing level II-IV TT without reconstruction of the IVC appears to not have a significant adverse effect on mid-term renal function after division of the left renal vein.

[Effect of surgical approach on radical nephrectomy outcomes: Comparative study between open and laparoscopic nephrectomy.] / Influencia de la vía de acceso para la nefrectomía radical en el tratamiento del cáncer renal: estudio comparativo entre cirugía abierta y cirugía laparoscópica.

OBJECTIVE: The aim of this study is to evaluate the influence of laparoscopy in patients with renal cancer treated with radical nephrectomy in terms of surgical time, hospital stay, postoperative complications and survival.MATERIAL AND METHODS: Retrospective study of 570 patients with renal cancer treated with radical nephrectomyin stage ≤pT3a. Differences between groups were analysed using ANOVA test for quantitative variables and Chi squared test for qualitative. In order to evaluate possible risk factors for longer hospital stay and surgical time, multivariate analysis was performed (lineal regression). For complications we performed binary logistic regression. Overall survival (OS), recurrence free survival (RFS) and cancer specific survival (CSS) were estimated using Kaplan Meier and compared using Log Rank test. Univariate and multivariate analysis was performed using Cox regression in order to identify independent risk factors for overall, cancer specific and recurrence mortality. RESULTS: Two cohorts: 361 (63.3%) open radical nephrectomies (ORN) and 209 (36.7%) laparoscopic (LRN). Surgical time was longer in LRN (p=0.001) globally. After the period when the learning curve was over these differences were no longer significant. Hospital stay was shorter in LRN (p=0.0001). cT stage (p=0.005) and surgical access (p=0.001) acted as independent risk factors for longer surgical time. 33,5% (121 patients) of the ORN had some sort of postoperative complication vs. 11% (23 patients) in the LRN group (p=0.0001). These differences were observed in the Clavien-Dindo's grade II group. Independent risk factors for postoperative complications observed were: ASA≥III (OR=1.82, p=0.004) and stage pT3a (OR=2.29,p=0.0001). Laparoscopy acted as a protective factor for complications (OR=0,26, p=0.0001). Surgical access did not influence RFS (HR=0.87, p=0.50), CSS(HR=0.69, p=0.12). CONCLUSIONS: Laparoscopic access to RN in patients with renal cancer in ≤pT3a stage increased surgical time only in the first years, reduced hospital stayand postoperative complications and did not influence RFS, OS or CSS.

Análisis multivariante mediante regresión de Cox para identificar variables predictoras independientes (VPI) de SLR y SCE. Todos los cálculos se han realizado con el paquete estadístico IBM® SPSS® statisticsv-21. RESULTADOS: Dos cohortes: 361 (63,3%) NRA y 209(36,7%) NRL. El tiempo de cirugía fue mayor en NRL (p=0,001) de forma global siendo las diferencias entre ambas en el periodo tras la curva de aprendizaje no significativas. La estancia media fue menor en NRL(p=0,0001). El estadio cT (p=0,005) y la vía de acceso (p=0,001) se comportaron como VPI de prolongación del tiempo quirúrgico. El 33,5% (121 casos) de las NRA presentaron algún tipo de complicación en el postoperatorio, frente al 11% (23 casos) de las NRL (p=0,0001). Esta diferencia se observó en complicaciones tipo II de Clavien. VPI de complicaciones postoperatorias: ASA≥III (OR=1,82, p=0,004) y el estadio pT3a (OR=2,29, p=0,0001). La laparoscopia se comportó como factor protector de complicaciones (OR=0,26, p=0,0001). La vía de acceso no influyó en la SLR (HR=0,87, p=0,50) ni en la SCE (HR=0,69,p=0,12). CONCLUSIONES: El acceso laparoscópico a la nefrectomía radical en pacientes con cáncer renal en estadio ≤pT3a aumentó el tiempo quirúrgico pero solo en los primeros años, presentó menor estancia y complicacionespostoperatorias y no influyó en la SG,SLR y SCE.

Beyond the Limits: How to Avoid a Surgical Nightmare in the Third and Subsequent Renal Transplantation Procedures.

PURPOSE OF REVIEW: Approximately, 25% of the patients with ESRD will enter the waiting list for kidney transplantation. Among these patients, almost 15% will require a retransplantation surgery. This review aims to summarize the most recent information on different controversial issues regarding retransplantation, to provide the reader with a clear and updated view on the topic. RECENT FINDINGS: Despite current evidence is mainly based on retrospective, small, single-center experiences, it seems clear that retransplantation remains a surgical and immunological challenge, for which the perioperative management still remains crucial to avoid mishaps. Different surgical approaches have been tested, but the general consensus advocates for the heterotopic extraperitoneal in first instance. Although higher immunological risk and complication rates are reported invariably in the available series, the benefits in terms of overall survival are superior to those obtained under dialysis, thus still representing the most recommended option for this group of patients.

Case report and literature review.] / Adenocarcinoma mucinoso de próstata tipo urotelial con células en anillo de sello y elevación del Ca 19.9 y Cea. Revisión de la literatura a propósito de un caso.

OBJECTIVE: Primary Mucin-producing Urothelial-type Adenocarcinoma of Prostate is extremely infrequent. The presence of signet ring cells is exceptional, more atypical in its mucinous variant. Anatomopathological and immunohistochemical study play a key role. METHODS: Bibliographic review and case report of a 66-year-old man with Ca 19.9 and CEA elevation, and normal PSA levels, associated with lower urinary tract symptoms (mucosuria, hesitancy and hematuria). He was diagnosed with mucin-producing urothelial- type adenocarcinoma of the prostate with signet ring cells by transrectal prostate biopsy after multiparametic MRI. RESULTS: We found 23 cases described in our review. No case diagnosed following an elevation of Ca 19.9 was found in the literature. In our case, after diagnosis, he was treated with retropubic radical prostatectomy and bilateral ilio-obturator lymph node dissection, with subsequent normalization of tumor markers; however, he presented secondary pulmonary involvement and pelvic tumor progression despite chemotherapy treatment. CONCLUSIONS: The elevation of associated tumor markers (Ca 19.9, CEA) is extraordinary. There is no treatment algorithm, however surgery (radical prostatectomy) with or without adjuvant chemotherapy treatment represents an alternative in its therapeutic management.

RESULTADOS: En la revisión efectuada se han encontrado descritos 23 casos. No se ha encontrado en la literatura ningún caso diagnosticado a raíz de una elevación del Ca 19.9. En nuestro caso, tras el diagnóstico fue tratado mediante prostatectomía radical retropúbica con linfadenectomía ilio-obturatriz bilateral, con normalización posterior de los marcadores tumorales; sin embargo, presentó afectación secundaria pulmonar y progresión tumoral pélvica a pesar de tratamiento quimioterápico. CONCLUSIONES: La elevación de marcadores tumorales asociada (Ca 19.9, CEA) es extraordinaria en este tipo de tumores. No existe un algoritmo de tratamiento, sin embargo la cirugía (prostatectomía radical) con o sin tratamiento adyuvante quimioterápico representa una alternativa en su manejo terapéutico.

[Prognostic factors of mortality in patients with urothelial bladder tumor treated with radical cistectomy.] / Factores pronósticos de mortalidad en pacientes con tumor urotelial de vejiga tratados con cistectomía radical.

INTRODUCTION: Radical cystectomy (RC) with pelvic lymphadenectomy is the treatment of choice in patients with muscle invasive bladder cancer (MIBC). OBJECTIVE: To identify clinical and pathological variables that influence global mortality (GM) and cancer specific mortality (CSM) in patients with urothelial bladder tumor (UBT) treated with RC. METHODS: Retrospective analysis of 517 patients diagnosed with UBT and treated with RC between 1986 and 2009. Demographic, clinical, surgical and pathological variables, as well as complications and evolution after RC were collected. A comparative analysis was carried out with Chi square and ANOVA test. Survival analysis was performed with the Kaplan-Meier method and the long-rank test. Univariate and multivariate analysis were performed using Cox regression to identify independent predictors of GM and CSM. RESULTS: 91% of the patients were males with a median age of 66 years. The most frequent local pathological stage was pT3 (32.6%), with lymph node involvement in 23.8% of the patients. After a median follow-up of 34 months, 170 patients were alive and 311 had died from any cause (63.5%), being UBT the cause of death in 225 patients (45%). Rates of global survival and cancer specific survival at 5 and 10 years were 45%/34.3% and 52.5%/46.6% respectively. On the multivariate analysis age ( p = 0.004), ASA ( p = 0.000), the existence of hydronephrosis ( p = 0.01), pT ( p = 0.000) and pN ( p = 0.003) were identified as independent predictors of GM, as well as pT ( p = 0.000) and pN ( p = 0.002) for CSM. CONCLUSIONS: Age, anesthetic risk, presence of hydronephrosis, pT and pN stage were identified as independent predictors of GM, as well as pT and pN stage for CSM.

[Intense urethrorrhagia after retropubic radical prostatectomy with selective embolization of the internal pudendal artery.] / Uretrorragia intensa tras prostatectomía radical retropúbica tratada con embolización selectiva de la arteria pudenda interna.

OBJECTIVE: Urethrorrhagia after radicalprostatectomy(RP) is very uncommon, regardless of the surgicalapproach used. Arterio-urethral fistula formation betweeninternal pudendal artery branches(IPA) and bulbarurethra is an exceptional finding. METHODS: We report what we consider the first series oftwo cases (one has already been published) of urethrorrhagiaafter open retropubic RP due to urethrovascular fistulaformation with its origin in the IPA or in one of its terminalbranches. RESULTS: Both cases were diagnosed with contrast-enhancedCT, confirmed with arteriography, and they weretreated with superselective transarterial embolization(STE)with spongostan. After 5 years, the first case maintainserectile function using tadalafil on demand. The other caseis in the 2nd postoperative month. CONCLUSION: Severe urethrorrhagia after RP is an exceptionalcomplication. The existence of an arterio-urethralfistula must be considered when both urethrorrhagia andabnormal bulbar enhancement in CT are present. Arteriographyallows to confirm the diagnosis, most frequently involvingIPA distal branches. STE is an effective and safetreatment.

OBJETIVO: La uretrorragia tras prostatectomía radical (PR) es muy infrecuente, independientemente del abordaje quirúrgico utilizado. La formación de fístulas arterio-uretrales entre ramas de la arteria pudenda interna (API) y la uretra bulbar, es un hallazgo excepcional.MATERIAL Y MÉTODOS: Presentamos la primera serie de 2 casos (uno ya publicado) de uretrorragia tras PR retropúbica abierta debidos a la formación de una fístula vascular con origen en la API o una de sus ramas terminales. RESULTADOS: Ambos casos fueron diagnosticados mediante TC con contraste intravenoso, confirmados con arteriografía, y tratados con embolización transarterial supraselectiva (STE) con espongostán. Tras 5 años, el primer caso conserva la función eréctil con tadalafilo a demanda. El 2º caso se encuentra en el 2º mes postoperatorio.CONCLUSIÓN: La uretrorragia severa tras PR es una complicación excepcional. Se debe sospechar la presencia de una fístula arterio-uretral ante la coexistencia de uretrorragia y realce bulbar anómalo en la TC, que suele ser la prueba de elección en el enfoque diagnóstico. La arteriografía permite confirmar los hallazgos, que suelen interesar a ramas dislates del territorio de la API. La STE es un tratamiento efectivo y seguro.

The existence of an arterio-urethral fistula must be considered when both urethrorrhagia and abnormal bulbar enhancement in CT are present. Arteriography allows to confirm the diagnosis, most frequently involving IPA distal branches. STE is an effective and safe treatment

[Locally advanced prostate cancer. Definition, diagnosis and treatment.] / Cáncer de próstata localmente avanzado. Definición, diagnóstico y tratamiento.

Prostate cancer is a disease that presents a wide spectrum from low aggressiveness localized to disseminated cancer. Locally advanced prostate cancer (LAPC) is a particularly difficult to manage phase of this spectrum. OBJECTIVES: We review the definition, diagnosis and treatment of this phase of the disease. METHODS: We performed a non systematic literature review of the most relevant features of this pathology. RESULTS: LAPC is more aggressive than organ confined disease. Its clinical diagnosis is not always easy. Local treatment, in spite of being aggressive with potential sequelae, seems to be advantageous in terms of patient survival. CONCLUSIONS: Prostate cancer local staging is currently based on multiparametric magnetic resonance imaging (mpMRI). Local radical treatment with surgery or radiotherapy, with probable addition of systemic treatment, offers promising results for disease control and quality of life improvement.

Cáncer de próstata localmente avanzado. Definición, diagnóstico y tratamiento / Locally advanced prostate cancer. Definition, diagnosis and treatment

El cáncer de próstata es una enfermedad que se presenta en un amplio espectro entre la enfermedad localizada poco agresiva y la diseminada. En ese espectro el cáncer de próstata localmente avanzado (CPLA) es una fase de manejo particularmente complejo. OBJETIVOS: En este artículo trataremos de hacer una revisión de la definición, diagnóstico, y tratamiento de esta fase de la enfermedad. Métodos: Se ha realizado una revisión no sistemática de la literatura de los aspectos más relevantes de la patología. Resultados: El CPLA es una fase del cáncer de próstata más agresiva que la enfermedad organoconfinada, cuyo diagnóstico clínico no siempre es fácil. El tratamiento local de la enfermedad, aunque agresivo y con potenciales secuelas, parece suponer una ventaja en la supervivencia para los pacientes. Conclusión: La estadificación local del cáncer de próstata se basa actualmente en la Resonancia Magnética multiparamétrica (RMNmp). El tratamiento radical local con cirugía o radioterapia (RT), con probable adición de tratamiento sistémico ofrece resultados prometedores para el control de la enfermedad y mejora de la calidad de vida

Factores pronósticos de recurrencia y mortalidad en pacientes con tumor de urotelio superior tratados con cirugía / Prognostic Factors of Recurrence and Mortality in Patients with Upper Urothelial Tumor Treated with Surgery

Objetivos: Identificación de factores pronósticos de recurrencia y mortalidad cáncer-específica en pacientes con tumor de urotelio superior tratados con cirugía. Materiales y métodos: Análisis retrospectivo de pacientes con tumor de urotelio superior operados entre 1999 y 2011 en nuestro centro (139 pacientes). Se recogieron variables demográficas, clínicas, diagnósticas y patológicas, así como el tratamiento realizado, complicaciones y evolución. Análisis descriptivo mediante la prueba de chi cuadrado (X2 ) para variables categóricas y el test ANOVA (Analysis of Variance) para variables continuas. Análisis univariante y multivariante mediante modelo de riesgos proporcionales de Cox. La significación estadística se consideró con un valor de p<0,05. Todos los cálculos fueron realizados con el paquete estadístico IBM® SPSS® Statistics v-21. Resultados: En el análisis multivariante se identificaron como factores predictores independientes de recurrencia el crecimiento sólido tumoral (cociente de riesgo [hazard ratio, HR]=4,02; p<0,001) y el alto grado citológico (G3) (HR=3,42; p=0,01). La presencia de tumor vesical previo o concomitante (HR=1,84; p=0,07) presentó una tendencia a la significación. Se identificaron como factores predictores independientes de mortalidad cáncer-específica la presencia de tumor vesical previo o concomitante (HR=2,23; p=0,02), el crecimiento sólido tumoral (HR=2,73; p=0,008), la presencia de hidronefrosis (HR=2,46; p=0,02) y el estadío patológico avanzado pT3-pT4 (HR=2,74; p=0,01). Conclusiones: En nuestra serie, la existencia de tumor vesical previo o sincrónico, el crecimiento tumoral sólido y el alto grado citológico se comportaron como factores pronósticos de recurrencia. La hidronefrosis, el tumor vesical previo o sincrónico, el estadío pT3-4 y el crecimiento tumoral sólido se comportaron como factores pronósticos de mortalidad cáncer-específica. (AU)

[Laparoscopic treatment of retroperitoneal fibrosis.] / Tratamiento laparoscopico de la fibrosis retroperitoneal.

OBJECTIVES: Retroperitoneal fibrosis is a disease that may condition a severe involvement of various organs, mainly upper urinary tract, even causing renal insufficiency. It was first described by Albarran in 1905 and it is also known as Ormonds disease. The correct diagnosis includes, in many cases, the performance of one or more tests: CT scan, MRI, renal scan, etc. It is often necessary the insertion of double J catheters on percutaneous nephrostomy tubes with the aim to preserve renal function. Initial treatment is medical, based on corticoids, and , less frequent, immunosuppressive or chemotherapy drugs. Surgery is the treatment of choice when ureteral entrapment by the fibrous plaque is not solved with medical treatment. Such operation may be performed with a conventional open approach (laparotomy) or by pure, hand assisted laparoscopic surgery, or robotic surgery. In all cases, the technique involves freeing the ureters from the fibrous plaque that entraps them, leaving them intraperitoneal, and it is recommendable to wrap them with an omental flap. The implantation of minimally invasive techniques has made that, in groups with experience in laparoscopy, open surgery is being abandoned and the laparoscopic approach indication is increasing. Our group has performed 10 laparoscopic ureterolysis from 2005. In two patients, it was bilateral. Despite surgical repair, two renal units were lost, keeping the rest with different levels of renal function depending on the preoperative level of disease. We did not have major complications and the mean hospital stay was 5.5 days. Although, there is not important published scientific evidence about this technique and it is unlikely we will have it in an immediate future, due to the rarity of this disease, and the different degree of involvement that conditions. It is not unreasonable to propose that, based on the literature reviewed and our own experience, laparoscopic approaches, despite being complex, may solve the ureteral entrapment with similar results to open surgery but less morbidity and shorter hospital stay.

Tratamiento laparoscopico de la fibrosis retroperitoneal / Laparoscopic treatment of retroperitoneal fibrosis

OBJETIVOS: La fibrosis retroperitoneal es una enfermedad que puede condicionar una afectación severa de distintos órganos, fundamentalmente del aparato urinario superior, pudiendo llegar incluso a ser la causa de una insuficiencia renal. Fue descrita por Albarrán en 1905 y se le conoce también como enfermedad de Ormond. El diagnóstico correcto que incluye, en muchos de los casos, la realización de una o varias pruebas: TAC (tomografía axial computarizada), RNM (resonancia nuclear magnética), gammagrafía renal, etc, obliga con relativa frecuencia, a la colocación de catéteres doble J o nefrostomías percutáneas con el fin de preservar la función de los riñones. El tratamiento inicial es médico, basado en la utilización de corticoides y, con menos frecuencia inmunosupresores o quimioterápicos. La cirugía es el tratamiento de elección cuando el atrapamiento ureteral por la placa fibrosa no queda resuelto con el tratamiento médico indicado en cada paciente. Dicha cirugía puede hacerse mediante un abordaje convencional (laparotomía) o mediante cirugía laparoscópica pura, manoasistida o robótica. En todos los casos la técnica consiste en liberar el o los uréteres de la placa fibrosa que los atrapa, dejarlos situados a nivel intraperitoneal y es recomendable utilizar un manguito de epiplon para envolverlos. La implantación cada vez mayor de las técnicas menos invasivas ha hecho que, en los grupos con experiencia laparoscópica, se vaya abandonando la cirugía abierta y sea cada vez más frecuente la indicación del abordaje laparoscópico. Nuestro grupo ha realizado 10 ureterolisis laparoscópicas desde el año 2005 en el que la indicamos por primera vez. En dos pacientes la técnica se realizó en los dos uréteres a la vez. Se perdieron, a pesar de la cirugía, dos unidades renales, manteniéndose el resto con distintos niveles de función renal dependiendo del grado de afectación que presentaban previamente. No tuvimos complicaciones mayores siendo la estancia media hospitalaria de 5,5 días. Aunque la literatura actual no tiene publicaciones sobre estas técnicas con importante evidencia científica y, por la rareza de la enfermedad y el distinto nivel de afectación que condiciona, es poco probable que las tengamos en un futuro inmediato, no es descabellado plantear, en base a la literatura revisada y a nuestra propia experiencia que, aunque complejos, los abordajes laparoscópicos pueden solucionar el atrapamiento ureteral con resultados similares a la cirugía abierta pero con menor morbilidad y menor estancia hospitalaria

[Recto-urethral fistula secondary to prostate cancer]. / Fístulas recto-uretrales secundarias a tratamiento de cáncer de próstata.

OBJECTIVES: There are various treatments forprostate cancer nowadays, including techniques that have been used for manyyears such as surgery and radiotherapy, and newer procedures that are gaining prominence in the Urological field like cryotherapy or HIFU (high intensity focused ultrasound). Rectourethral fistula is a rare complication that demands the urologist a great capacity; it may happen after either existent treatment. METHODS: PubMed literature review with articles published during the last 10 years using the terms "rectourethral fistula" and "prostate cancer". EVIDENCE SINTHESIS: We present the current situation of rectourethral fistula secondary to prostate cancer in terms of epidemiology, diagnosis and treatment, with special focus on the various types of fistulae and their management. We comment on general features in relation to surgical management of this pathology; type of approach, type of repair, use of flaps, concomitant fistula and urethralstenosis, delay of surgery and bowel diversion. We describe the surgical techniques more frequently used today and their limitations. We present the results published by different groups with each of these techniques, as well as the corresponding recommendations based on each group's experience. CONCLUSIONS: Rectourethral fistula is a surgical challenge for the urologist. We must choose the appropriate management in accordance to the characteristics of the fistula.

Usefulness of the Memorial Sloan Kettering Cancer Center nomogram in the prognosis of patients treated with radical cystectomy for invasive bladder cancer.

OBJECTIVES: To evaluate the usefulness of the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram for prediction of recurrence probability in our series of patients who have undergone radical cystectomy for bladder cancer. METHODS: 397 patients underwent radical cystectomy for bladder cancer between 1986 and 2005. 165 patients were excluded:21 due to exitus in the immediate postoperative period, 32 due to previous radiation therapy, 6 due to neoadjuvant chemotherapy, 5 due to inability to complete follow-up, 15 that did not undergo lymphadenectomy and 86 who were alive at the time of review with less than 5 years of follow-up. Patients were classified into recurrence risk groups: organ-confined tumors (pT0-2 pN0 ), extra-bladder involvement (pT3-4 pN0) and lymph node involvement (pN+). Survival analysis was performed using the Kaplan-Meier method. Five-year recurrence-free survival by risk groups in our series was compared with the one estimated using the MSKCC nomogram using a ROC curve. RESULTS: We analyzed 232 patients. Follow-up in patients who died of cancer was 25 ± 25 months. For alive patients and those who died of other causes, follow-up was 120 ± 39 months. Pathology studies revealed 42.7% organ-confined tumors , 33.2% with extra-bladder involvement and 24.1% with lymph node involvement. The five-year recurrence free survival analysis according to the Kaplan-Meier method stratified by risk groups was: pT0-2 76%, pT3-4 51%, pN+ 31%. The probability of recurrence free survival according to the MSKCC nomogram in the same risk groups was: 85% ± 5%, 62% ± 10% and 25% ± 13%, respectively. The area under the ROC curve was 0.795 (95% CI 0.739-0.852) CONCLUSION: In our series, the MSKCC nomogram constitutes a useful tool for predicting 5-year cancer free survival in patients who undergo radical cystectomy.

Prognostic factors in patients with stage pT0/pT1/pTa in the radical cystectomy specimen.

OBJECTIVES: To identify risk factors for progression in patients with invasive bladder carcinoma who were pT0/pT1/pTa after cystectomy. METHODS: We analyzed the clinical records of 97 post-cystectomy pT0/pT1/pTa patients for the following variables: hydronephrosis, carcinoma in situ (CIS), lymphovascular invasion, history of non-muscular invasive disease, residual tumor in the specimen and lymphatic invasion (pN). pN+patients were excluded from definitive analysis. The quantitative and qualitative variables were analyzed using standard statistics. The chi-square test was used to analyze associations between categorical variables. Univariate Cox proportional hazard regression analysis (enter method) was performed. The Kaplan-Meier method was used to evaluate survival and the log-rank test to assess differences between groups. Statistical significance was set at p<0.05. The analysis was performed using SPSS version 15.0. RESULTS: The study sample included 97 cases. The specimen was staged at T2 in 97% of patients after transurethral resection (TUR); After cystectomy, the specimen was staged as pT0 (R0) in 44.3% and pT1/Ta (R1) in 55.7%. Median follow-up was 47 months. Lymph node metastasis were detected in 5.2% of patients (pN+rpar; and had a negative impact on survival (p=0.02). Overall survival was 59.8% and cancer-specific survival 76.6%. Univariate analysis showed a relationship between tumor progression and the presence of CIS (p < 0.001), lymphovascular invasion (p=0.049), and hydronephrosis(p < 0.001). In the multivariate analysis, only the presence of CIS in the transurethral resection was associated with reduced cancer-specific survival (HR 100.5; 95% CI, 10.8 to 933.1; pp<0.001). CONCLUSIONS: Although the prognosis of stage pT0/pT1/pTa carcinoma in the cystectomy specimen is excellent, some patients experience progression. The presence of CIS in the transurethral resection was an independent predictor of recurrence in these cases.
