RESUMO

OBJECTIVE: To better understand the safety and diagnostic yield of percutaneous core-needle biopsy (PCNB) for upper tract urothelial carcinoma (UTUC). METHODS: Of 444 patients undergoing radical nephroureterectomy (RNU) for UTUC between 2009 and 2017 at our institution, 42 who had PCNB prior to RNU were identified for analysis. Endpoints included safety, diagnostic yield, and concordance with RNU pathology. PCNB specimens were deemed histologically concordant with RNU specimens for cases when cytologic evaluation of biopsy specimen and corresponding pathologic evaluation of RNU specimen both made a histologic diagnosis of urothelial carcinoma. RESULTS: Median tumor size was 3.8 cm (1.2-10.2 cm). All lesions arose from the pelvicalyceal system. CT-guidance was utilized in 52% (n = 22), and ultrasound-guidance in 48% (n = 20). Relative to RNU pathology, 95% of PCNBs demonstrated histologic concordance. Histologic grade was provided in 69% (n = 29) of PCNBs, with a 90% (n = 26) concordance with surgical pathology. Grades 1-2 and 3 complications occurred in 14.3% (n = 6) and 2.4% (n = 1), respectively. At a median follow-up of 28.2 months (range, 1.2-97.1 months) after biopsy, no cases of radiographic tract seeding were identified. CONCLUSION: In our cohort of 42 patients undergoing RNU for UTUC, PCNB appeared a safe diagnostic tool with high histologic yield and grade concordance. With greater than 2 years of follow-up, no cases of tract seeding were identified.

RESUMO

OBJECTIVE: To evaluate differences in the incidence of benign ureteroenteric stricture, we compared stricture rates of robot-assisted radical cystectomy (RARC) and open radical cystectomy (ORC) using Surveillance, Epidemiology, and End Results-Medicare data. METHODS: We identified 332 RARC and 1449 ORC performed between 2009 and 2014 to determine stricture rates at 6, 12, and 24 months following surgery. We defined ureteroenteric stricture as the need for procedural intervention. Additionally, we compared the incidence of stricture diagnosis. Multivariable proportional hazards regression was performed to determine factors associated with stricture development. RESULTS: The incidence of ureteroenteric stricture at 6 and 12 months was higher for RARC vs ORC at 12.1% vs 7.0% (P < .01) and 15.0% vs 9.5% (P = .01), respectively. RARC vs ORC stricture incidence at 2 years did not differ significantly at 14.6% vs 11.4% (P = .29). Similarly, the stricture diagnosis rates were significantly lower following ORC at 6, 12, and 24 months (P < .05). In adjusted analysis, RARC (HR 1.64, 95%CI 1.23-2.19) and preoperative hydronephrosis (HR 1.51, 95% CI 1.17-1.94) were associated with the development of stricture. Higher hospital volume was associated with a lower risk of stricture (HR 0.40, 95%CI 0.26-0.63). CONCLUSION: RARC is associated with a higher rate of ureteroenteric stricture diagnosis and intervention on a population-based level that is mitigated by higher hospital volume. A significant study limitation is inability to differentiate extracorporeal vs intracorporeal diversion. However, a stricture complication compounds the financial burden of care and efforts must be pursued to improve this surgical outcome.

RESUMO

OBJECTIVE: To calculate the incidence of renal graft urothelial carcinoma in renal transplant recipients in a national large retrospective cohort and to analyze circumstances of diagnosis, treatment and outcome. MATERIAL AND METHODS: We conducted a national retrospective, multicenter study. Thirty two transplant centers were asked to report its cases of kidney graft tumors and the number of kidney transplantations performed since the beginning of their transplantation activity. RESULTS: Between January 1988 and December 2018, 56,806 patients were transplanted in the 32 centers participating in this study. Among this cohort, 107 renal graft tumors (excluding lymphoma) were diagnosed among them 11 renal transplant recipients were diagnosed with an urothelial carcinoma in the kidney graft. The calculated incidence was 0.019%. The median patient age at the time of diagnosis was 56.7 years (49.8-60.9) and 51.4 years (47-55.7) at the time of transplantation. The median time between transplantation and diagnosis was 66.6 months (14.3-97). Before treatment, 3 patients had graft tumor biopsies revealing urothelial carcinomas, 3 patients had endoscopic retrograde uretero-pyelography showing lacunary images. Two patients had a diagnostic flexible ureteroscopy with biopsies. Total nephrectomy was performed in all cases. CONCLUSION: Even though occurring in the context of immune suppression, most of these tumors seemed to have a relatively good prognosis. With regards to functional outcomes histological diagnosis should always be sought for before radical treatment of these tumors. Treatment should be a transplant nephrectomy including all the ureter with a bladder cuff to ensure optimal carcinologic control.

RESUMO

OBJECTIVE: To identify the effect of preoperative anemia on the prognosis of patients with upper tract urothelial carcinoma (UTUC) following radical nephroureterectomy. METHODS: Clinicopathological and prognosis data on 686 patients with UTUC who underwent RNU at Peking University First Hospital between January 2000 and December 2013 were retrospectively analyzed. Preoperative anemia was defined as hemoglobin <130 g/L in men and <120 g/L in women based on the World Health Organization classification. The Kaplan-Meier method with log-rank test was applied to estimate the effect of anemia on survival. The associations of clinicopathologic features with overall survival and cancer-specific survival were evaluated using univariate and multivariate Cox regression models. RESULTS: There were 303(44.2%, 303/686) male and 383(55.8%, 383/686) female patients, and the median age was 68 years (interquartile range: 60-74 years). In all, 320 (46.6%, 320/686) patients were anemic before surgery. The median follow-up duration was 47 months. In all, 160 (23.3%) patients died, 141 (20.6%) died of cancer and 19 (2.7%) died of other disease or accidents. Preoperative anemia was associated with gender (P=0.002), age (P<0.001), lymph node positive (P=0.026), increased tumor grade (P=0.018), concomitant carcinoma in situ (P=0.038), tumor necrosis (P=0.007) and poor renal function (P<0.001). In univariate analysis, overall mortality was correlated with pre-operative anemia (P<0.001), gender (P=0.009), hydronephrosis (P=0.024), tumor stage (P<0.001), lymph node positive (P<0.001), tumor grade (P<0.001), tumor architecture(P<0.001), sarcomatoid differentiation (P=0.013), history of ureteroscope (P=0.033) and tumor hemorrhage (P<0.001); cancer-specific mortality was correlated with preoperative anemia (P=0.001), gender (P=0.001), hydronephrosis (P=0.043), tumor stage (P<0.001), lymph node positive (P<0.001), tumor grade (P<0.001), tumor architecture (P<0.001), sarcomatoid differentiation (P=0.016), history of ureteroscope (P=0.028) and tumor hemorrhage (P=0.003). A multivariate Cox proportional hazards model indicated that preoperative anemia was an independent prognositic predictor for overall mortality (P<0.001, HR=1.861) and cancer-specific mortality (P=0.003, HR=1.688). CONCLUSION: The preoperative anemia is an independent risk factor for cancer-specific survival and overall survival. Hemoglobin levels should be considered during patient counseling and in decision-making for further therapy.

RESUMO

RATIONALE: Bladder cancer (BC) is commonly diagnosed in the urinary system and the most common subtype is transitional urothelial carcinoma (TCC). Even with the best treatment, tumor recurrence and metastases always occur. While clinicians commonly observe the metastases to pelvic lymph nodes, liver, lung, and bone, it may infrequently spread to some uncommon locations. PATIENT CONCERNS: The patient was a 67-year-old man with a diagnosis of high-grade TCC with squamous differentiation in the bladder and prostate. Subsequently, radical cystoprostatectomy, adjuvant radiotherapy, and chemotherapy were performed. However, he felt intermittent right scrotal pain about 1 year later. DIAGNOSIS: Ultrasound strongly suggested a testicular neoplasm of right testis, but the left was normal. INTERVENTIONS: The patient underwent a right radical orchiectomy and histopathology confirmed testicular metastatic neoplasm from bladder. Moreover, further examination with positron emission tomography revealed no visible distant spread of the urothelial carcinoma. OUTCOMES: No signs of tumor recurrence or distant metastasis were visible under follow-up 1 year after radical orchiectomy. LESSONS: Testicular mass may be metastatic tumor during follow-up for patients who were diagnosed as BC, especially for TCC with variant histology. The reason of this could be explained of residual micrometastases after surgery and need more examination to discover local micrometastases to apply more aggressive treatment.

RESUMO

BACKGROUND: Papillary squamotransitional cell carcinoma of the uterine cervix is a rare neoplasm, a subtype of transitional cervical carcinoma that appears to be a variation of squamous cervical carcinoma. It has a disposition toward metastasis at an advanced stage and local recurrence. Owing to the difficulty of illustrating the invasion histologically, misdiagnosis is likely to affect the patient's prognosis. CASE PRESENTATION: We present a case report of an 81-year-old Caucasian patient with squamotransitional cell carcinoma with unusual clinical behavior that was primarily thought to be ovarian cancer. According to the clinical examination and radiologic imaging, the patient had no vaginal bleeding and a normal cervix. Nevertheless, the tumor was already metastasized at the retroperitoneal tissue and at the right ovary. Computed tomography-guided biopsy of the right adnexa gave no further clarification. Although the tumor resembled urothelial cancer, this diagnosis was dismissed because of the results of immunohistochemistry analysis with CK7+, CK5+, and CK20-. Because of the differential diagnosis of ovarian cancer, we decided in favor of an exploratory surgical approach. Hysterectomy with bilateral adnexectomy, extensive retroperitoneal tumor debulking, and infragastric omentectomy was performed by laparotomy. Histopathology revealed a squamotransitional cervical cancer as the primary tumor with a tumor stage of pT3b, pN1 (1/2), V0, RX, G2, corresponding to International Federation of Gynecology and Obstetrics stage IIIB. CONCLUSIONS: As far as we are aware, this is the first report of papillary squamotransitional cell carcinoma of the uterine cervix metastatic to the ovary without vaginal bleeding and with a clinically and radiologically unsuspicious cervix. Physicians should always contemplate papillary squamotransitional cell carcinoma of the uterine cervix in unclear cases with ovarian metastasis, especially if the histology indicates a transitional cancer (CK7+ and CK20-), before proceeding with treatment. More cases are needed to illuminate the clinical characteristics and categorization of papillary squamotransitional cell carcinoma of the uterine cervix.

RESUMO

We here report a case of bladder urothelial carcinoma, a rare tumor in subjects less than 40 years, as well as our therapeutic experience. The study involved a 37-year old patient with a history of urinary tract infection and of staying at a riparian area (bilharzia) presenting with hypogastralgia and total macroscopic hematuria. Clinical and paraclinical assessment showed voluminous bladder mass suggesting infiltrative tumor without local or distant lymph node or organic involvement. Surgical management was based on resection of bladder tumor and biopsy followed by total cystectomy with substitutive ileal enterocystoplasty. The postoperative course was uneventful. The patient also underwent adjuvant chemotherapy and vitamin B-12 therapy. Clinical and paraclinical assessment, performed after 6 and 12 months, showed no recurrence.

RESUMO

A patient in her 70s presented with confusion, agitation and psychotic symptoms. No cause was found until the incidental discovery of urothelial carcinoma. Upon removal of the tumour, the psychiatric symptoms largely improved leaving residual symptoms indicative of dementia. The patient had not been diagnosed with dementia previously and this made for an interesting disease presentation and progression. We discuss the challenges of diagnosing delirium and dementia in complex patients such as these and the importance of identifying a cause when cognition has been impaired by a suspected delirium.

RESUMO

BACKGROUND: To test the effect of radical cystectomy (RC) with chemotherapy vs only chemotherapy on overall mortality (OM) in metastatic urothelial carcinoma of the urinary bladder (mUCUB). METHODS: Within the Surveillance, Epidemiology, and End Results registry (2004-2016), we identified patients with mUCUB. Stratification was made according to treatment: RC with chemotherapy vs only chemotherapy. Kaplan-Meier plots and multivariable Cox regression models were used before and after 1:1 propensity score (PS) matching and inverse probability of treatment weighting (IPTW). RESULTS: Of 2414 patients with mUCUB, 500 (21.0%) vs 1914 (79.0%) were treated with RC with chemotherapy vs only chemotherapy, respectively. In multivariable Cox regression models, RC with chemotherapy was associated with lower OM in the overall cohort (hazard ratio [HR], 0.5; P < .001), after 1:1 PS matching (HR, 0.5; P < .001), after IPTW (HR, 0.5; P < .001) and after accounting for number and location of metastases (HR, 0.5; P < .001). However, higher overall survival after RC with chemotherapy was only observed in patients with one metastatic site (21 vs 16 months; P = .001). CONCLUSION: In contemporary patients with mUCUB, RC with chemotherapy is associated with lower OM rates, relative to chemotherapy alone, but only in patients with a single metastatic site. These individuals accounted for the vast majority of patients in whom an RC was performed, despite the presence of metastatic disease.

RESUMO

OBJECTIVE: To determine if the timing of radical cystectomy for variant histology of urothelial carcinoma has an impact on survival. Variant histology has been associated with aberrant behavior compared to pure urothelial carcinoma, however the timing of surgery for these patients has not been studied. MATERIALS AND METHODS: We identified 363 patients with cT2-T4N0M0 urothelial carcinoma who underwent radical cystectomy without perioperative intravesical and/or systemic therapy from 2003 to 2014. Clinicopathologic data were compared between pure urothelial carcinoma and variant histology. The time from diagnosis to radical cystectomy was analyzed as a continuous variable and dichotomized at 4-, 8-, and 12-weeks to determine impact on oncologic outcomes. RESULTS: Patients with variant histology, when compared to those with pure urothelial carcinoma, were more likely to present with extravesical disease (P <.01), be upstaged (P <.01), have lymphovascular invasion (P <.01) and have lymph node metastasis at radical cystectomy (P = .02). The median days to radical cystectomy did not differ between pure urothelial and variant histology. On multivariable analysis controlling for age, comorbidities, tumor stage, lymph node status, lymphovascular invasion, and surgical margins, every month in delay was associated with a worse overall survival for variants (HR = 1.36, P = .003). At an 8-week delay or longer, those with variant histology had a statistically worse survival (P = .03). CONCLUSION: For patients with variant histology, delays in surgery were associated with an increased risk of death.

RESUMO

PURPOSE: There are only a few studies on characteristics and outcomes of late recurrence (LR) of urothelial carcinoma of bladder (UCB) after radical cystectomy (RC). The objective of this study was to assess characteristics and oncological outcomes of such LR that developed 5 years after RC. MATERIALS AND METHODS: We retrospectively reviewed 570 patients who underwent RC and bilateral regional lymphadenectomy for UCB at our institution. Comparisons of post-recurrence disease-specific survival (DSS) according to the timing of recurrence and the site of recurrence were performed using Kaplan-Meier survival curves and log-rank test. Cox regression model was fitted to assess factors for post-recurrence DSS. RESULTS: Disease recurrence occurred in 214 (37.5%) patients, including 20 (9.3%) who had LRs. Median time from RC to recurrence was 13.0 (interquartile range 6.0-32.0) months. There were no significant differences in clinicopathological factors between early- and late-recurrence groups. Post-recurrence 5-year DSS was not significantly different (21.6 vs. 14.1%, p = 0.344) between early- and late-recurrence groups. However, it was worse in the nonurothelial recurrence group compared to that in the urothelial recurrence group (14.0 vs. 19.4%, p = 0.056). Older age (HR 1.03, 95% CI 1.01-1.05, p = 0.001), nonorgan-confined disease at RC (HR 1.73, 95% CI 1.15-2.61, p = 0.008), and lymph node invasion (HR 1.58, 95% CI 1.01-2.45, p = 0.043) were significant predictors for post-recurrence 5-year DSS. CONCLUSIONS: LR after RC with lymphadenectomy is not common. However, it cannot be overlooked. LR had similar characteristics to early recurrence. Interestingly, the time to recurrence did not affect post-recurrence survival.

RESUMO

OBJECTIVE: To investigate the oncological impact of incidental prostate cancer (iPCa) found during radical cystoprostatectomy (RCP) on overall survival (OS) prognosis of urothelial carcinoma of the bladder (BCa). PATIENTS AND METHODS: A total of 122 RCP cases resected between 2002 and 2012 at our center were included for study. Survival of BCa patient was compared using the Kaplan-Meier method and the log-rank test. Cox proportional hazards regression models were used to analyze the impact of iPCa on the 5-year overall mortality of BCa patients after RCP. RESULTS: Among the 122 BCa cases that underwent RCP, 38 cases (31.1%) had iPCa, in which, 17 cases (44.7%) were identified as clinically significant iPCa (csPCa). BCa patients with iPCa were older (71 vs 64 years, p = 0.004) and had higher preoperative PSA level (3.1 ng/mL vs 1.4 ng/mL, p = 0.017) when compared to those without iPCa. Cases with iPCa showed a more favorable 5-year OS than cases without iPCa, although this difference did not reach statistical significance (p = 0.219). When excluding the higher risk cases with Gleason score (GS) ≥ 4 + 3 and/or preoperative PSA > 10 ng/mL, BCa patients with iPCa showed a significantly longer OS than cases without iPCa on univariate analysis (p = 0.044), but not on multivariate analysis (p = 0.125). CONCLUSION: Our results demonstrated that the frequent findings of low-risk iPCa in BCa patients could indicate the potential possibility of shared pathogenesis pathways between iPCa and BCa. Future study with a larger cohort is warranted to validate this result.

RESUMO

Aim: To assess mortality from bladder cancer following a diagnosis of nonmuscle-invasive bladder cancer. Materials & methods: This is a SEER registry-based study. The risk of death from bladder cancer was compared with that of the general population. Cox proportional model was performed to calculate the hazard ratio (HR) for death according to baseline characteristics. Results: The bladder cancer-specific mortality at 20 years was 11%; and it was higher for black patients compared with white patients (adjusted HR: 1.711 [95% CI: 1.564-1.872]; p < 0.0001); additionally, it was higher for patients older than 70 years old compared with younger patients (adjusted HR: 2.005 [95% CI: 1.916-2.099]; p < 0 .0001). The risk of bladder cancer mortality increased after diagnosis of a recurrent bladder cancer (both nonmuscle-invasive and muscle-invasive; adjusted HR: 6.97 [95% CI: 6.56-7.40]; p < 0 .0001). Conclusion: Important predictors for death from bladder cancer following a diagnosis of nonmuscle-invasive bladder cancer include older age at diagnosis and black race.

Open radical nephroureterectomy (NU) with removal of the ureter and bladder cuff is the 'gold standard' in the treatment of high-grade urothelial cancers of the upper urinary tract. A salient issue is the management of the distal ureter and bladder cuff at time of surgery. Which technique confers superior oncologic benefit is of particular interest since this disease process is notoriously plagued with high intravesical recurrence rates. Although open radical NU is the 'gold standard', the maturation of minimally invasive surgery formidably challenges approaches considered 'gold standard'. We thus sought to critically review the literature comparing perioperative and oncologic outcomes in the approaches used to manage the distal ureter and bladder cuff in patients undergoing radical NU.

RESUMO

PURPOSE: We investigated the impact of previous, simultaneous or subsequent bladder cancer on the clinical outcomes of upper urinary tract urothelial carcinoma. MATERIALS AND METHODS: We retrospectively collected data on 2,668 patients who underwent radical nephroureterectomy of nonmetastatic upper urinary tract urothelial carcinoma in 1995 to 2009. We evaluated the impact of bladder cancer on overall mortality and the factors predictive of subsequent bladder cancer. RESULTS: A total of 631 patients (23.7%) had previous or simultaneous bladder cancer. Patients with previous or simultaneous bladder cancer had significantly shorter overall survival than patients without previous or simultaneous bladder cancer (HR 1.29, 95% CI 1.09-1.53, p=0.0026). Of the 2,037 patients without previous or simultaneous bladder cancer 683 (33.5%) subsequently had bladder cancer after radical nephroureterectomy. Of patients with pT0-2 disease those with subsequent bladder cancer had significantly shorter overall survival than patients without subsequent bladder cancer (HR 1.81, 95% CI 1.23-2.67, p=0.0025). In patients with pT3-4 disease subsequent bladder cancer was not associated with worse overall survival. On multivariable analyses independent predictors of subsequent bladder cancer were gender, preoperative urine cytology and clinical node status in the preoperative setting, and gender, adjuvant chemotherapy and pathological node status in the postoperative setting. CONCLUSIONS: Bladder cancer was significantly associated with worse clinical outcomes after radical nephroureterectomy of upper urinary tract urothelial carcinoma. Preventing subsequent bladder cancer in patients with pT0-2 upper urinary tract urothelial carcinoma may lead to better prognosis in those who undergo radical nephroureterectomy.

RESUMO

BACKGROUND: Physicians doubt percutaneous nephrostomy (PCN) insertion on cancer related hydronephrosis patients causes tumor seeding and worse cancer control. In this article, we attempted to determine if preoperative PCN alters cancer control in upper tract urothelial cancer (UTUC) patients. METHODS: Retrospective analysis of UTUC patients in a single center from 2005 to 2015. Exclusion criteria included lymph node metastasis, and patients underwent perioperative adjuvant chemotherapy or radiotherapy. There were 664 patients in this analysis, with clinico-pathological data being collected retrospectively for Cox-regression statistical analysis. Outcomes were measured by local recurrence, distant metastasis and cancer-specific death with Kaplan-Meier curves. RESULTS: There were respectively 25 and 639 UTUC cancers in the preoperative PCN and non-PCN insertion groups with mean follow-up duration of 37.9 and 48.6 months, respectively. The preoperative PCN group consisted of 17 patients (68%) with tumor located in the ureter, while the PCN-negative group included 236 patients (36%) with tumor located in the ureter being statistically significant. These two groups were comparable in gender, age, follow-up duration, tumor stage, and pathological features of the UTUC. As for the cancer control in the PCN group, 4(16%), 1(4%) and 1(4%) had local recurrence, distant metastasis and cancer-specific death respectively; in the non-PCN group, 101(15.8%), 96(15%) and 72(11.2%) exhibited local recurrence, distant metastasis and cancer-specific death respectively. Statistical analysis showed no difference in oncologic outcomes between these two groups.(p = 0.804, 0.201 and 0.254). CONCLUSIONS: Preoperative percutaneous nephrostomy on upper-tract urothelial cancer poses little risk on tumor seeding and could be considered as part of treatment strategy if renal function preservation is needed.

RESUMO

BACKGROUND: No definitive evidence exists regarding the clinical significance of histologic variants (HV) in upper urinary tract cancer. We investigated the impact of HV on prognosis in patients with upper urinary tract cancer following radical surgery. PATIENTS AND METHODS: We retrospectively analyzed 451 patients with upper urinary tract cancer who underwent radical nephroureterectomy at six affiliated hospitals from 1990 to 2015. Patients with distant metastatic disease prior to surgery and those who received neoadjuvant chemotherapy were excluded, leaving 441 eligible patients. Patients were classified into two groups: pure urothelial carcinoma (UC) and HV. The clinicopathological variables of each group were examined using Kaplan-Meier plots and proportional Cox hazard ratios (HR) to compare the oncological outcomes between the two groups. RESULTS: HV included 37 patients (8%). Compared with the pure UC patients, HV patients had significantly worse recurrence-free survival (RFS) and cancer-specific survival (CSS; RFS p = 0.0002, CSS p = 0.0001). Multivariate analysis for RFS revealed HV were independent predictors (HR 1.92; p = 0.026), but the association did not remain significant for CSS. There was no significant difference in CSS between the adjuvant chemotherapy (AC) group and the non-AC group for all HV patients, except in patients with ≥ pT3 tumor or positive lymph node status where the AC group had significantly favorable CSS. CONCLUSIONS: HV in upper urinary tract cancer are independent predictors for RFS, but not for CSS. AC improved CSS for HV patients with ≥ pT3 tumor or positive lymph node status.
