RESUMEN

BACKGROUND: Limited data are available on patients with carcinoma in situ (CIS) of the bladder managed according to current clinical practice guidelines. OBJECTIVE: To assess the patterns of recurrence, progression to muscle-invasive bladder cancer (MIBC), and upper tract urothelial carcinoma (UTUC) in patients with CIS, and to compare the effectiveness of adequate versus inadequate bacillus Calmette-Guérin (BCG) immunotherapy. DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysis of 386 patients with CIS of the bladder with or without associated pTa/pT1 disease treated with BCG between 2008 and 2015. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Kaplan-Meier estimations and an inverse probability of treatment weighting (IPTW)-Cox regression were performed to compare recurrence-free survival (RFS) and progression-free survival (PFS) and UTUC incidence over time for patients who received adequate versus inadequate BCG treatment. RESULTS AND LIMITATIONS: The median follow-up was 70.5 mo. At 5 and 10 yr, RFS was 82% and 52%, PFS was 93.6% and 75.8%, and UTUC incidence was 1.7% and 2.9%, respectively. Most recurrence (73.6%) and progression (69.1%) events occurred in the first 3 yr of follow-up, while 38.7% of UTUC incident events were recorded after 5 yr of follow-up. IPTW-Cox regression revealed that patients who received BCG treatment had a lower risk of recurrence (hazard ratio [HR] 0.21, 95% confidence interval [CI] 0.13-0.34), progression (HR 0.46, 95% CI 0.25-0.87), and UTUC incidence (HR 0.24, 95% CI 0.09-0.64). Limitations include the retrospective design and potential selection bias. CONCLUSIONS: Patients with CIS of the bladder show a high risk of recurrence, progression, and UTUC incidence. Most of these outcomes occur during the first 3 yr of follow-up, but a significant proportion of the events occur at long-term follow-up. Although receipt of adequate BCG treatment improves outcomes, intensive and long-term surveillance may be warranted. PATIENT SUMMARY: We investigated the long-term cancer control outcomes for patients with carcinoma in situ (CIS; cancerous cells that have not spread from where they first formed) of the bladder. Patients with CIS have a high risk of cancer recurrence and progression. Treatment with bacillus Calmette-Guérin (BCG) improves outcomes.

RESUMEN

There is an increasement on the incidence of tumours within the population of renal transplanted, from three to five times over general population. Related to urological tumours, it emphasizes an increase in the incidence of the renal carcinoma, around 4,7% against 3% on general population. In this case, we present a 56-year-old patient, who suffered a renal transplant 8 years ago. Incidentally, it is diagnosed a 3 cm mass at the back face of the transplanted kidney, suggestive of renal neoplasm. Given the characteristics of the mass, of the patient and because of the good graft function, we propose the non-sparing surgery of the transplanted kidney as treatment. The patient went back home 6 days after the surgery, with a creatinine value of 106 micromol/L. The pathology of the piece was a papilar carcinoma, type II, pT1aG3, free margins of tumour. The non-sparing techniques like the partial nephrectomy, the criotherapy and the radiofrequency ablation, can be useful and must be considered when it is tried to preserve the renal function, overall in case of bilateral tumours or solitary kidney, and in small and/or eccentric tumours. Renal neoplasms necessarily does not imply the loss of the graft and allows a similar handling to transplanted patient, applying conservative techniques in selected cases.

RESUMEN

INTRODUCTION: The da Vinci robotic laparoscopic surgery, has been shown in radical prostatectomy, optimal functional and oncological results with a lower learning curve, greater comfort and vision for the surgeon, and proper preservation of the neurovascular bundles. This has led to begin the experience with robotic radical cystectomy (RRC). OBJECTIVES: Review our initial experience in CRR, evaluating surgical and functional results obtained, and also immediate and short-term complications. MATERIAL AND METHODS: Between December 2007 and January 2009 we performed nine robotic radical cystoprostatectomy and in seven patients robotic lymphadenectomy (LDN). Five patients had a muscle-invasive disease and 4 non-muscle invasive bladder cancer. The median age was 57 years (range 34-81). Urinary diversion was performed extracorporeally in all cases, 3 cases an ileal conduit and 6 an Studer neobladder in 3 of these 6 cases, the urethra-neobladder anastomosis was performed intracorporeally. RESULTS: The average time of surgery was 300 minutes (range 280-420) in the ileal conduit and 360 (range 330-540) in the Studer. No cases required conversion or blood transfusion. The median number of nodes removed by LDN robotics was 10 (range 6-18). The pathology revealed 3 pT0. 2 CIS, 3 pT3, 1 pT4b (positive margins). With a median follow up of 7 months there have been no peritoneal implant and only one ureteral stenosis. Oral diet was initiated in 5 cases at 48 hours. Of the 6 patients with preserved sexual function preoperatively and followup of more than 3 months, 2 had full erection at 1 month, 2 at 3 and 6 months, and the remaining 2 presented with a full erection with 5 PD inhibitors at 3 and 9 months. All patients with neobladder presented correct daytime continence. The average hospital stay was 8.5 days (range 7-19). CONCLUSIONS: The radical robotic cystectomy with extracorporeal reconstruction of the urinary diversion offers good early functional and surgical outcomes. The careful preservation of the neurovascular bundles in radical pelvic surgery provides excellent results in urinary and sexual function.

RESUMEN

Laparoscopic radical nephrectomy is considered to be the technique of choice in the mangement of stage T1 and T2 renal cancer, though increased mastery of this alternative type of surgery has served to expand its indications. In any case, these procedures have a series of limitations which are tied to the intrinsic characteristics of laparoscopic surgery, and which are associated with the patient and tumor characteristics, and the experience of the surgeon. The present study discusses the different indications and establishes the current limits of laparoscopic surgery applied to the management of renal tumors. Its role in cell-reducing therapy in metastatic disease, and the methods available for reducing tumor implantation in the surgical ports are also commented.

RESUMEN

OBJECTIVE: Renal cryotherapy has been described as a minimally invasive procedure that represents an alternative for selected patients with small renal tumors. Our preliminary experience with this procedure is reported. MATERIAL AND METHODS: [corrected] Eighteen patients with 21 tumors with a mean tumor size of 2.2 cm (1-4) in the preoperative CT scan underwent renal cryotherapy using a double freeze-thaw cycle. The group consisted of 14 males (64%) and 4 females (18% with a mean age of 68 years (32-84). All patients had undergone prior surgery for renal tumor in the treated or the opposite kidney. A transperitoneal laparoscopic approach was used in all patients. RESULTS: Mean operating time was 196 minutes (120-140), and no patient received transfusions during or after surgery. No complications occurred in 14 patients (64%). Perirenal abscess, splenic laceration, ureteral lesion, and polar artery lesion occurred in one patient each. Peroperative biopsy was performed in 5 patients (22.7%) and was positive for renal cancer in two cases, while material was insufficient in three patients. Mean hospital stay was 6 days (2-16). Creatinine levels were 106 mg% (48-230) before surgery and 123 mg/% (52-270) 6 months after surgery. A CT scan was performed in all patients one and six months after surgery, showing a residual enhancement area in two of them. Sixteen patients (88.8%) are disease-free after a mean follow-up time of 46 months (6-116). Metastatic disease occurred in two patients (11%) in the setting of a prior renal tumor in the same or the opposite kidney and required treatment with antiangiogenic agents. CONCLUSIONS: This is the largest series reporting renal cryosurgery in Spain, in complex cases and with adequate follow-up. Results are encouraging and allow for considering renal cryotherapy among the minimally invasive procedures for nephron-sparing surgery.

RESUMEN

Background: The first-line treatment in cases of chylous leakage is conservative, and operation should be considered only in patients who fail to respond to this treatment. The main clinical concern is the difficulty of intraoperative localization of the site of leakage that can affect surgical outcome. Case Presentation: A 33-year-old man presented with a 4-month history of abdominal pain and weight loss. CT scan revealed enlarged retroperitoneal lymph nodes. Retroperitoneal lymph node biopsy was performed owing to the suspicion of lymphoproliferative disease, with a pathological result of nonspecific adenitis. Because of persistence of pain, an abdominal CT scan showed a large left retroperitoneal fluid collection that was found to be compatible with chyle after drainage. Conservative treatment was established, but because of its failure, surgical management was attempted by the laparoscopic approach. Intraoperative direct lymph node injection of methylene blue was used as a leakage point location strategy that allows selective ligation of the site of leakage. Thereafter a gradual reduction in chyle output to zero was observed. Conclusion: The laparoscopic approach could be a feasible and successful method for the management of chyle leakage in patients refractory to conservative treatment. Intraoperative direct lymph node injection of methylene blue could be a useful technique to facilitate detection of the site of leakage during operation.

RESUMEN

OBJECTIVES: Bacillus Calmette-Guérin (BCG) has proven its efficacy in the treatment of carcinoma in situ (CIS) of the prostatic urethra. We performed a retrospective study to evaluate the use of intravesical instillations of BCG in patients with carcinoma in situ involving prostatic ducts after complete transurethral resection (TUR). MATERIAL AND METHODS: Eligibility for the study was CIS of the prostatic urethra involving prostatic ducts. Previous instillation with BCG was an exclusion criterion. Patients were treated with intravesical BCG Connaught (81 mg) administered once a week, over a 6-wk period. TUR loop biopsies of the prostate were performed only when a macroscopic tumor was present. RESULTS: In this retrospective study of 11 patients, 8 (73%) presented with macroscopic tumor in the prostatic urethra. Ten patients (91%) had a simultaneous superficial bladder carcinoma. Eight patients (73%) had tumoral involvement of the bladder neck region. After a median follow-up of 27 mo (n=10 patients), the response in the prostatic urethra was 82%, and the response in the bladder due to superficial tumor recurrence was 64%. Two patients with residual ductal disease in the prostatic urethra were subsequently treated with cystoprostatectomy and are currently free of disease. In one of those patients, the cystoprostatectomy specimen did show prostatic stromal invasion. Another patient developed distant metastatic disease and died a few months after diagnosis. Thus, progression was encountered in two patients (18%). Currently, 90% of patients are alive without evidence of disease and 72.7% have benefitted from this bladder preservation strategy. CONCLUSION: Intravesical BCG is a feasible treatment option for patients with CIS involving prostatic ducts. In this retrospective study, bladder preservation was successful in 8 of 11 patients (70%) and there was only one oncologic death. Obviously, these patients need a careful follow-up with cystoscopy and cytology to detect either recurrence or progression and in those with persistent disease after the initial BCG induction therapy, prompt cystectomy is indicated.

RESUMEN

OBJECTIVES: To perform a retrospective evaluation of surgical complications and morbidity in patients undergoing radical retropubic prostatectomy (RRP) as elective treatment for organ-confined prostate cancer in our center with previous transurethral resection of the prostate (TURP). METHODS: Between 1980-2004 we performed 59 radical prostatectomies in patients with previous TURP. We analyze the morbidity and mortality of the RRP, its functional outcomes, and the accordance between clinical and pathological stage. RESULTS: Mean time between TURP and RRP was 16 months. Mean patient age at the time of diagnosis was 63 years. Clinical stage: 16 T1a, 18T1b, 20T1c, 3T2a, 2T2b. Average surgical time was 180 minutes. Intraoperative events: technical difficulties in the dissection of the gland 57%, bladder neck preservation 27%, neuro vascular bundles preservation 3.39%, ureter ligation 1.69%, rectal laceration 1.69, urethrorrhagia 1.69%, urinary leak 5%, and blood transfusions 11.8%. Postoperative complications: urinary tract infection 10.17%, wound infection 10.17%, pelvic hematoma 5.08%, deep vein thrombosis 1.69%, and one sudden death of unknown cause one month after surgery. Pathologic report: 49pT2b, 8 pT3 and 2pT4. Late complications: erectile dysfunction 85.7%, vesicourethral anastomosis stenosis 10.3%, and complete urinary incontinence 3%. CONCLUSIONS: Radical retropubic prostatectomy in patients with previous TURP is technically more difficult and has comparable outcomes to RRP patients without previous TURP.

RESUMEN

OBJECTIVES: To report one case of renal cell carcinoma and contralateral metacronous oncocytoma, and to perform a bibliographic review on the topic. METHODS: 52-year-old male patient with history of right radical nephrectomy for renal cell carcinoma. On his ten-year follow-up multiple lesions appeared in the left kidney. Partial nephrectomy was performed. Pathological study showed three oncocytomas. CONCLUSIONS: The presence of metacronous lesions in the contralateral kidney of a patient with history of renal cell carcinoma is rare. The presence of the same histological type of tumor should always be suspected and the management should follow this suspicion. Contralateral metacronous oncocytoma is a rare pathology which has not been reported in the literature so far.

RESUMEN

OBJECTIVES: To review indications, techniques and results of laparoscopic adrenalectomy. METHODS: We retrospectively review our experience with 8 cases of transperitoneal laparoscopic adrenalectomy (2 pheochromocytomas, 4 aldosteromas, 1 myelolipoma and 1 non functioning adenoma). RESULTS: Mean operative time was about 3 hours, with an mean estimated blood loss of 200 cc. Mean Hospital stay was 2.5 days, complication rate was 10%, being conversion to open surgery between 5 and 10%. CONCLUSIONS: Laparoscopic adrenalectomy is the operation of choice for functioning adrenal tumours and for incidentally diagnosed tumours < or = 6 cm that have increased in size in successive radiographic examinations.

RESUMEN

OBJECTIVES: To assess the feasibility and a validity of the Spanish version of the FACT-P and its relation to urinary symptoms. METHODS: The Spanish version of the FACT-P was self-administered to 60 Prostate Cancer patients (pts) waiting to undergo radical treatment and 20 age-matched controls (con) with a negative biopsy. Clinical stage for patients was T1c in 34 and T2 in 26. FACT-P was analysed for internal consistency (Chronbach's a) and relation to symptom scales (IPSS, IPSS bother score and incontinence questionnaire (ICI-SF)). RESULTS: Feasibility (evaluable questionnaires) was 80.9 for con and 95% for pts. Internal consistency was high for all sub-scales (alpha > 0.7). Emotional well-being subscale and IPSS were significantly higher in pts. (worse emotional wellbeing and more lower urinary tract symptoms). There were no statistically significant differences between pts and con. in any of the other FACT-P sub-scores nor in symptom scores. Correlations were found between some FACT-P sub-scores and bother score. CONCLUSIONS: The Spanish version of the FACTP is feasible and psychometrically valid. Pts undergoing treatment for localized disease have similar QoL that a control group, but higher scores for emotional distress and IPSS.
