Abstract
Intraductal spread of urothelial carcinoma (UC) is not an uncommon finding in bladder cancer that requires appropriate clinical management. The presence of prostatic stromal invasion in non-muscle-invasive bladder cancer upstages the disease, necessitating cisplatin-based neoadjuvant chemotherapy and subsequent cystroprostatectomy. However, the identification of prostatic stromal invasion can be challenging, especially in biopsy and transurethral resection specimens. We assess the utility of D2-40, CK5/6, and high-molecular-weight cytokeratin (HMWCK) immunohistochemistry as an ancillary tool to differentiate prostatic stromal invasion from intraductal UC spread. We reviewed 13 cystoprostatectomies performed for UC with prostatic involvement. The presence of stromal invasion was histologically determined by the presence of circumferential retraction artifact, paradoxical differentiation, complex architecture, and desmoplastic reaction. The areas of interest were subsequently stained with D2-40, CK5/6, and HMWCK (clone 34βE12). Four bladder biopsies were used as a control to assess labeling in the benign urothelium. Nine cases had histologic evidence of prostatic stromal invasion (4 transmurally through bladder wall). D2-40 highlighted basal cells in all benign prostatic ducts and was consistently negative in UC, benign urothelium, prostatic adenocarcinoma, and benign luminal prostatic epithelium. D2-40 and CK5/6 performed similarly for intraductal UC, labeling only the basal cell layer with the exception of 1 case with squamous differentiation where CK5/6 exhibited full thickness staining. HMWCK diffusely stained 9 of 10 intraductal UCs without squamous differentiation and 1 intraductal UC with squamous differentiation. All 8 cases of invasive UC without squamous differentiation were negative for D2-40. Seven of these cases had focal CK5/6 and diffuse HMWCK staining. In 1 case of invasive UC with squamous differentiation, all stains were positive. D2-40 is expressed in prostatic basal cells, but it is not expressed in the benign or neoplastic urothelium. D2-40 and CK5/6 effectively highlight the intraductal spread of UC. While invasive UC is negative for D2-40, CK5/6 is usually patchy and localized to the periphery of the tumor nests. HMWCK often demonstrates diffuse staining in both scenarios. However, these stains do not perform well in cases of UC with squamous differentiation. Thus, D2-40 can be used as an ancillary tool to rule out prostatic stromal invasion.

Abstract
BACKGROUND: In patients with non-invasive urothelial carcinoma of the prostatic urethra (PUC), treatment with Bacillus Calmette-Guérin (BCG) could be beneficial. OBJECTIVE: To assess the response rates to BCG in the different tumor stages, to describe the clinical impact of transurethral resection of the prostate (TURP) before BCG treatment, and to review the side effects of BCG treatment for PUC. METHODS: A systematic search was conducted using the PubMed database to identify original studies between 1977 and 2019 reporting on PUC and BCG. RESULTS: Of a total of 865 studies, ten were considered for evidence synthesis. An indication for BCG treatment was found in non-stromal invasive stages (Tis pu, Tis pd) and in stromal infiltrating cases (T1) of primary and secondary PUC when transitional cell carcinoma was the histology of origin. Studies including patients treated with TURP before BCG showed a better local response in the prostatic urethra with a higher disease free survival (DFS) (80–100% vs. 63–89%) and progression free survival (PFS) (90–100% vs. 75–94%) than patients in studies in which no TURP was performed. However, this difference in recurrence and progression in the prostate neither affected the total PFS (57–75% vs. 58–93%), nor the disease specific survival (70–100% vs. 66–100%). CONCLUSIONS: The use of resection loop biopsies of the prostatic urethra in appropriate cases during the primary work-up for suspected PUC, as well as the use of the current TNM classification for PUC, need to be improved. BCG therapy for non-stromal invasive stages of PUC show a good local response. Local response is further improved by a TURP before BCG therapy, although the overall prognosis does not seem to be affected. Further evidence for BCG treatment in the rare cases of stromal invasive PUC is needed. Specific side effects of BCG treatment for PUC are not reported.

Abstract
BACKGROUND The optimal management of non-invasive (mucosal and/or ductal) urothelial carcinoma of the prostate remains elusive and there is a paucity of data to guide treatment. OBJECTIVE Our objective was to systematically review and synthesize treatment responses to conservative management of non-invasive prostatic urothelial carcinoma using intravesical therapy. METHODS A systematic literature search using MEDLINE, EMBASE, Cochrane Library, SCOPUS, and Web of Science databases from inception to November 2019 was performed. Risk of bias assessment was performed using the Newcastle-Ottawa scale for non-randomised studies. Pooled estimates of complete response in the bladder and prostate and prostate only were performed using a random effects model. Pre-specified subgroup analyses were generated to assess differences in complete responses for: BCG therapy vs other agents, ductal vs mucosal involvement, CIS vs papillary tumors and TURP vs no TURP. RESULTS Nine studies including 175 patients were identified for inclusion in the systematic review and meta-analysis. All were retrospective case series and most evaluated response to BCG therapy. The pooled global complete response rate for intravesical therapy was 60%(95%CI: 0.48, 0.72), and for prostate 88%(95%CI: 0.81, 0.96). Pre-specified analyses did not demonstrate statistically significant differences between subgroups of interest. CONCLUSIONS Management of non-invasive prostatic urothelial carcinoma using intravesical therapy yields satisfactory results. Caution should be taken in treating patients with papillary tumors and ductal involvement, as data for these populations is limited. TURP may not improve efficacy, but is required for staging. Current recommendations are based on low quality evidence, and further research is warranted.

Abstract
CONTEXT.— The 8th edition of the American Joint Committee on Cancer (AJCC) staging manual changed the tumor, node, metastasis (TNM) classification systems of genitourinary malignancies in 2017. However, some of the changes appear not well appreciated or recognized by practicing pathologists. OBJECTIVE.— To review the major changes compared with the 7th edition in cancers of the prostate, penis, testis, bladder, urethra, renal pelvis/ureter, and kidney and discuss the challenges that pathologists may encounter. DATA SOURCES.— Peer-reviewed publications and the 8th and 7th editions of the AJCC Cancer Staging Manual. CONCLUSIONS.— This article summarizes the updated staging of genitourinary malignancies, specifically highlighting changes from the 7th edition that are relevant to the pathologic staging system. Pathologists should be aware of the updates made in hopes of providing clarification and the remaining diagnostic challenges associated with these changes.

Abstract
Background: The value of preoperative chemotherapy to prostatic stromal invasive urothelial bladder cancer remains uncertain. This study presented the pathological response and oncological outcomes of male patients with cT4a urothelial bladder cancer managed with preoperative chemotherapy followed by radical cystectomy. Materials and methods: Data were collected retrospectively from male patients with cT4a urothelial bladder cancer, who underwent radical cystectomy with or without preoperative chemotherapy. Patient characteristics and pathological response were compared. The Kaplan-Meier method and multivariable Cox regression were used to analyze recurrence-free survival and overall survival. Results: From 1989 to 2016, 90 male patients with primary cT4a urothelial bladder cancer underwent radical cystectomy at the institution, 55 (61%) did not have preoperative chemotherapy and 35 (39%) had preoperative chemotherapy. The preoperative chemotherapy group had more lymphovascular invasion on primary transurethral resection of bladder tumor (31.4% vs 18.2%, p = .2) and more clinically positive nodal disease (31.4% vs 10.9%, p = .09). At radical cystectomy, the preoperative chemotherapy group had more tumor down staging (60% vs 29.1%, p = .005), less lymphovascular invasion (40% vs 54.5%, p = .05) and less positive nodal disease (25.7% vs 45.5%, p = .006). Hydronephrosis, lymphovascular invasion and age >70 were associated with worse recurrence-free survival and overall survival (p < .05). Tumor down-staging was associated with improved recurrence-free survival and overall survival (p = .003, p = .03, respectively). Preoperative chemotherapy alone was not associated with improved oncologic outcomes. Conclusions: Preoperative chemotherapy is associated with cT4a bladder cancer down-staging, decreased lymphovascular invasion and decreased positive nodal disease. Preoperative chemotherapy provides survival benefit to those who achieved pathological response.

Abstract
The differential diagnosis between high-grade prostate carcinoma and infiltrating urothelial carcinoma (UC) in transurethral resection prostate specimens as well as cystoprostatectomy specimens may often be challenging due to morphologic and clinical overlap of the 2 entities. Such distinction has critical therapeutic and staging consequences, yet it is hampered by both issues in morphology and by the low accuracy rates of single immunohistochemical markers, as reported in literature. This review aims to provide a comprehensive analysis of the available morphological and immunohistochemical parameters, which may allow to discriminate between prostate carcinoma and urothelial carcinoma in the proper clinical context and to discuss their diagnostic applications in daily practice.

Mucinous and secondary tumors of the prostate. Mod Pathol 2018; 31:S80-S95.

Abstract
Primary mucinous tumors and secondary tumors involving the prostate gland are relatively uncommon, however they have important diagnostic, therapeutic, and prognostic implications. The primary mucinous tumors of the prostate include mucinous (colloid) adenocarcinoma of the prostate, prostatic adenocarcinoma with mucinous features, and mucinous adenocarcinoma of the prostatic urethra (mucin-producing urothelial-type adenocarcinoma of the prostate). Mucinous adenocarcinoma of the prostate is defined as a primary prostatic acinar tumor characterized by the presence of at least 25% of the tumor composed of glands with extraluminal mucin. This diagnosis can only be made in radical prostatectomy specimens. Recent studies have shown that these tumors have a similar or in some cases better prognosis than conventional prostatic adenocarcinoma treated by radical prostatectomy. The preferred terminology for tumors that are composed of <25% extraluminal mucinous component in radical prostatectomy specimens is 'prostatic adenocarcinoma with mucinous features.' All cases of prostatic adenocarcinoma with extraluminal mucinous components in prostate needle core biopsies or transurethral resection of the prostate specimens are also referred to as 'prostatic adenocarcinoma with mucinous features.' Mucinous adenocarcinoma of the prostatic urethra (mucin-producing urothelial-type adenocarcinoma of the prostate) as the name implies, does not arise from prostatic acini or ducts, and is a distinct entity that arises from the prostatic urethra usually from urethritis glandularis or glandular metaplasia with malignant transformation, and is analogous to adenocarcinoma with mucinous differentiation arising from the urinary bladder. This tumor is aggressive and has a relatively poor prognosis. The most common secondary tumors that arise from adjacent organs and spread (direct extension or metastasis) to the prostate gland, include urothelial carcinoma of the bladder and colorectal adenocarcinoma. Other secondary tumors that may involve the prostate include metastatic epithelial tumors from several other sites, malignant melanoma and soft tissue tumors.

Abstract
The paradigm of pathologic stage (pT) categorization in bladder cancer remains the depth of invasion into the different histologic layers of the bladder wall. However, the approaches to assigning pT stage category toward an enhanced outcome stratification have been marked by challenges and innovations, due in part to our growing appreciation of the surprisingly perplexing bladder histoanatomy. Upstaging of pT1 tumors after radical cystectomy is substantial and underscores the potential value of pT1 substaging in transurethral resection (TUR) specimens. The 2017 American Joint Committee on Cancer tumor-node-metastasis system recommends pT1 substaging but recognizes the need to optimize the approach. Over the years, the cut-off for microinvasion has been significantly lowered to 0.5 mm and is now a promising scheme for pT1 (micrometric) substaging. Unlike the micrometric approach, histoanatomic substaging using muscularis mucosae (MM) and vascular plexus as landmarks is less feasible in TUR specimens and inconsistent in stratifying the outcome of pT1 tumors. The lamina propria possesses inherent variations in depth, MM, and vascular plexus dispositions that should be factored in future pT1 substaging proposals. Histoanatomic variations among the bladder regions also occur, and studies suggest that trigone and bladder neck cancers may have more adverse outcomes. The muscularis propria (MP), besides being the essential histologic landmark for assigning pT2 stage category, is also considered a surrogate for the adequacy of TUR, furthering the importance of identifying its presence in TUR specimens. MP, however, may be mimicked by hyperplastic or isolated MP-like MM muscle bundles in the lamina propria with overstaging implications, and caution should be exercised in distinguishing these 2 muscle types morphologically and immunohistochemically. Presence of additional superficial MP unique from the detrusor muscle proper may also complicate staging at the trigone and ureter insertion sites. With regard to the depth of MP invasion, large and multicenter studies have reaffirmed the prognostic significance of pT2a/b subcategories. It is revealed that there are at least 3 ways used to demarcate the irregular MP to perivesical soft tissue junction, and use of a common criterion indicates improvement in pT2b/pT3a staging reproducibility. Although studies have shown significantly poorer outcome in pT3b compared with pT3a tumors, this designation has a substantial reliance on the prosector's gross assessment of perivesical soft tissue invasion which if performed incorrectly may lead to staging inaccuracy of pT3 tumors. The 8th edition of the American Joint Committee on Cancer has updated the staging schema for bladder cancers with concomitant prostatic stromal invasion and cancers within bladder diverticula. Because of 2 possible pT designations, prostatic stromal invasion in TUR specimens should not be automatically staged as either pT4a or pT2 (urethral). Recent data support that bladder cancer invading into the seminal vesicle has comparable outcome to pT4b tumors. Interestingly, several studies in pT4a tumors, which are staged based on sex-specific organs, have shown poorer outcome in females than males after radical cystectomy, and while there are possibly several reasons, they may also include anatomic factors. Despite the progress has been made, work remains to be done to inform future bladder cancer pT category definitions and their reproducibility in application and prognostication.

Abstract
PURPOSE Biopsy of the prostatic urethra is an integral part of clinical staging in patients prior to radical cystoprostatectomy (RC) and urinary diversion. We examined whether preoperative transurethral resection (TUR) biopsy was associated with final apical urethral margin status and hypothesized that a negative biopsy could replace intraoperative frozen section for decision making regarding the feasibility of orthotopic neobladder reconstruction. METHODS TUR biopsy, frozen section, urethrectomy, and final apical urethral margin pathologic data were extracted from the charts of men who had undergone RC at the Houston Methodist Hospital between 1987 and 2013. TUR biopsies were performed at five and seven o'clock adjacent to the verumontanum. A positive biopsy was defined as the presence of in situ or invasive urothelial carcinoma. Clinical and perioperative variables were analyzed using descriptive and inferential statistics. RESULTS We reviewed the medical records of 272 men. Preoperative TUR biopsies of the prostatic urethra were negative in 74% (200/272) and positive in 26% (72/272) of men. The overall incidence of apical urethral margin positivity on final pathology was 2.2% (six of 272). Four men underwent primary or secondary urethrectomy. TUR biopsy negative and positive predictive values for apical urethral margin positivity were 99.5% (95% confidence interval (CI): 97.2 to 99.9) and 6.9% (95% CI: 2.3 to 15.5), respectively. CONCLUSIONS The incidence of a positive apical urethral margin was low in patients undergoing RC. A negative preoperative TUR biopsy of the prostatic urethra was reliably associated with a negative final margin, obviating the need for intraoperative frozen section. Furthermore, a positive biopsy was not reliably associated with final margin status. These data will aid in the counseling of patients regarding the feasibility of neobladder reconstruction.

Abstract
PURPOSE To evaluate the prognostic relevance of different prostatic invasion patterns in pT4a urothelial carcinoma of the bladder (UCB) after radical cystectomy. MATERIALS AND METHODS Our study comprised a total of 358 men with pT4a UCB. Patients were divided in 2 groups-group A with stromal infiltration of the prostate via the prostatic urethra with additional muscle-invasive UCB (n = 121, 33.8%) and group B with continuous infiltration of the prostate through the entire bladder wall (n = 237, 66.2%). The effect of age, tumor grade, carcinoma in situ, lymphovascular invasion, soft tissue surgical margin, lymph node metastases, administration of adjuvant chemotherapy, and prostatic invasion patterns on cancer-specific mortality (CSM) was evaluated using competing-risk regression analysis. Decision curve analysis was used to evaluate the net benefit of including the variable invasion pattern within our model. RESULTS The estimated 5-year CSM-rates for group A and B were 50.1% and 66.0%, respectively. In multivariable competing-risk analysis, lymph node metastases (hazard ratio [HR] = 1.73, P<0.001), lymphovascular invasion (HR = 1.62, P = 0.0023), soft tissue surgical margin (HR = 1.49, P = 0.026), absence of adjuvant chemotherapy (HR = 2.11, P<0.001), and tumor infiltration of the prostate by continuous infiltration of the entire bladder wall (HR = 1.37, P = 0.044) were significantly associated with a higher risk for CSM. Decision curve analysis showed a net benefit of our model including the variable invasion pattern. CONCLUSIONS Continuous infiltration of the prostate through the entire bladder wall showed an adverse effect on CSM. Besides including these patients into clinical trials for an adjuvant therapy, we recommend including prostatic invasion patterns in predictive models in pT4a UCB in men.

Low grade urothelial carcinoma mimicking basal cell hyperplasia and transitional metaplasia in needle prostate biopsy. Int Braz J Urol 2016; 42:247-52.

Abstract
PURPOSE The vast majority of urothelial carcinomas infiltrating the bladder are consistente with high-grade tumors that can be easily recognized as malignant in needle prostatic biopsies. In contrast, the histological changes of low-grade urothelial carcinomas in this kind of biopsy have not been studied. MATERIALS AND METHODS We describe the clinicopathologic features of two patients with low-grade bladder carcinomas infiltrating the prostate. They reported dysuria and hematuria. Both had a slight elevation of the prostate specific antigen and induration of the prostatic lobes. Needle biopsies were performed. At endoscopy bladder tumors were found in both cases. RESULTS Both biopsies showed nests of basophilic cells and cells with perinuclear clearing and slight atypia infiltrating acini and small prostatic ducts. The stroma exhibited extensive desmoplasia and chronic inflammation. The original diagnosis was basal cell hyperplasia and transitional metaplasia. The bladder tumors also showed low-grade urothelial carcinoma. In one case, the neoplasm infiltrated the lamina propria, and in another, the muscle layer. In both, a transurethral resection was performed for obstructive urinary symptoms. The neoplasms were positive for high molecular weight keratin (34BetaE12) and thrombomodulin. No metastases were found in either of the patients, and one of them has survived for five years. CONCLUSIONS The diagnosis of low-grade urothelial carcinoma in prostate needle biopsies is difficult and may simulate benign prostate lesions including basal cell hyperplasia and urothelial metaplasia. It is crucial to recognize low-grade urothelial carcinoma in needle biopsies because only an early diagnosis and aggressive treatment can improve the prognosis for these patients.

Abstract
PURPOSE We determined the likelihood that transurethral resection biopsy of the prostatic urethra adjacent to the verumontanum would detect prostatic involvement of urothelial carcinoma in patients with bladder carcinoma. MATERIALS AND METHODS We compared precystectomy transurethral resection biopsy specimens of the prostatic urethra with those of the matched radical cystoprostatectomy in 272 patients with urothelial carcinoma of the bladder. All prostates were evaluated by whole mount step sections. RESULTS Prostatic involvement by urothelial carcinoma was detected by transurethral resection biopsy or radical cystoprostatectomy in 101 patients (37.1%). Transurethral resection biopsy detected urothelial carcinoma in 72 cases with 71.3% sensitivity and 100% specificity. The overall accuracy of transurethral resection biopsy to detect urothelial carcinoma of the prostate was 89% (positive and negative predictive values 100% and 86%, respectively). Invasive prostatic urothelial carcinoma arising from the prostatic urethra was detected by transurethral resection biopsy in 21 of 26 patients (81%) while prostatic carcinoma in situ was detected in 39 of 52 (75%). Transurethral resection biopsy detected prostatic invasive urothelial carcinoma resulting from transmural invasion of a bladder tumor in 4 of 15 patients. CONCLUSIONS Prostatic involvement by urothelial carcinoma of the bladder was found in 37.1% of patients. Transurethral resection biopsy missed most tumors resulting from transmural invasion of the bladder primary lesion. Carcinoma in situ and invasive urothelial carcinoma arising from the prostatic urethra were detected in most cases. Transurethral resection biopsy of the prostatic urethra can complement staging and support clinical decision making with respect to neoadjuvant chemotherapy and planning for an orthotopic neobladder.

Abstract
AIM Primary bladder urothelial carcinoma (UC) may involve the prostate with differing management depending on whether tumour is in situ or invades the prostatic subepithelium or fibromuscular stroma. We aim to understand challenges in reporting UC within prostate transurethral resection (TUR). METHODS A retrospective review from 2007 to 2010 identified prostate TUR performed for primary bladder UC. RESULTS 25.1% of cystoprostatectomy patients (60/239) had a prior prostate TUR; 129 patients had a prostate TUR for UC and 50.4% (65/129) were given a neoplastic diagnosis. Prostatic fibromuscular stroma was present in 84.6% of cases, with a comparable rate among surgeons. Diagnostic concordance of UC versus a non-neoplastic diagnosis was 96.7%, with rare cases initially diagnosed as non-neoplastic having in situ UC on review. Of reports with invasive tumour, 19.4% did not specify extent of invasion (e.g., bladder muscularis propria, prostate fibromuscular stroma) and 13.9% had discordant extent of invasion on review. Terminology typically used for bladder (lamina propria/muscularis propria) was found in 23.1% of reports without explicit reference to the bladder or prostate. CONCLUSION This study reveals difficulties in reporting UC within prostatic TUR specimens. We recommend documenting tumour extent and referencing the organ of origin if ambiguous anatomical terms are used.

Abstract
The role of a regional lymphadenectomy in the surgical management of high-grade invasive bladder cancer has evolved over the last several decades. A growing body of evidence suggests that an extended lymph node dissection may provide, not only improved prognostic information, but also a clinically significant therapeutic benefit for both lymph node-positive and -negative patients undergoing radical cystectomy. The extent of the primary bladder tumor, number of lymph nodes removed and the lymph node tumor burden are important prognostic variables in patients undergoing cystectomy. In addition, the concept of lymph node density may further improve stratification of lymph node-positive patients. The historical development and contemporary rationale for an extended pelvic lymphadenectomy in patients undergoing radical cystectomy are reviewed.

Abstract
Treatment decisions for bladder cancer patients are mainly based on the depth of bladder wall invasion by the tumor. In this article, we review the conventional MRI and exhibit a recently emerged diffusion-weighted imaging (DWI) of urinary bladder cancer for T-staging. We discuss limitations of conventional MRI, scanning protocols of DWI, normal pelvic findings on DWI, determination of T-stage using DWI, and pitfalls of DWI. DWI provides high contrast between bladder cancer and background tissue because the cancer shows markedly high SI. DWI has high sensitivity for detecting the stalk seen in stage Ta or T1. An inflammatory change or fibrosis surrounding the tumor mimics the invasion of bladder cancer on T2-weighted imaging or enhanced MRI and could lead to over-staging, but DWI could differentiate them clearly because these benign changes do not show high SI on DWI. DWI is also useful for detecting ureteral, urethral, and prostatic extension by means of the urethra. DWI provides more accurate information on the extent of bladder cancer and contributes to determination of the treatment strategy.

Abstract
OBJECTIVES Urothelial carcinoma (UC) is a multifocal disease that may develop in any location of the urinary tract, including the prostate. We analyze the types of prostate involvement due to UC, their diagnosis, risk factors and the clinical implications of this entity. MATERIAL AND METHODS Analysis of original, review articles and publications related to prostate involvement due to UC. The study included works published in the period of 1985-2011, most of which were obtained from the search in PubMed. RESULTS Prostate involvement due to UC has been observed frequently in both non-muscle invasive bladder cancer (NMIBC) series and prolonged follow-up (39%) as in radical cystectomy series (15-48%). Prostatic involvement may occur in the mucosa and ducts (superficial involvement) or prostate stroma (invasive involvement), a fact that has prognostic and therapeutic implications. Stromal involvement may have both a bladder and intraurethral origin. Carcinoma in situ, multifocality, bladder neck/trigone cancer, and previous history of tumor recurrence are the factors that have been m ore consistently associated to prostate involvement due to UC. The incidence of prostatic involvement by UC in patients with NMIBC increases over time when risk factors exist. In these cases, a prostatic urethral biopsy should be performed during the follow-up. Conservative treatment with transurethral resection and BCG is possible in case of superficial involvement of the prostatic urethra, assuming its risk of progression. Patients subjects to cystectomy and with prostate involvement due to UC have a greater risk of urethral recurrence. The elevated incidence of prostatic adenocarcinoma and prostatic involvement by UC in cystectomy specimens makes it necessary to be very selective when indicating prostate-sparing cystectomy. Chemotherapy may be an option in an attempt to improve survival of patients with prostatic stromal involvement. CONCLUSIONS Prostatic involvement by UC is not uncommon and it has important implications in the management of patients with NMIBC and in those who have an indication for or have undergone radical cystectomy.

Abstract
For primary bladder tumors, distinguishing urothelial carcinoma (UC) invading the fibromuscular stroma of the prostate (pT4a) from in situ UC involving prostatic ducts can be difficult. Immunohistochemical markers (cytokeratin [CK]5/6, CK5, CK7, CK20, p53, p63, high-molecular-weight keratin [HMWK], androgen receptor, prostate-specific antigen [PSA], prostate specific acid phosphatase [PSAP], laminin, CD44s, CD141) were assessed for their usefulness in determining depth of UC invasion in the prostate. In cystoprostatectomy specimens containing in situ UC in prostatic ducts, both CK5/6 and CK5 clearly differentiated prostatic basal cells from in situ UC. The remaining markers were not effective in determining depth of tumor invasion. Double-stain combinations CK7/CK5 and p53/CK5 were performed and robustly color contrasted in situ tumor from surrounding basal cells. The use of CK5/6, CK5, CK7/CK5, or p53/CK5 is recommended to assist in determining the depth of UC invasion in the prostate when histologic findings are equivocal.

Abstract
AIMS To evaluate the utility of p63 and high molecular weight cytokeratin in the distinction between urothelial carcinoma with prostatic stromal invasion and urothelial carcinoma with colonisation of prostatic ducts and acini which may be challenging on H&E, especially for general pathologists who may occasionally encounter these cases. METHODS A search of surgical pathology and consultation files was made for cystoprostatectomy specimens with confirmed urothelial carcinoma with prostatic stromal invasion. Intensity for both p63 and high molecular weight cytokeratin within the tumour cells were scored as negative/weak or strong. RESULTS A total of 34 cases were identified, 23 (68%) of which had associated foci of urothelial carcinoma with colonisation of prostatic ducts and acini. Mean patient age was 68.5 years (range 44-88 years). In all cases, basal cells of benign prostatic glands showed strong staining for both p63 and high molecular weight cytokeratin. Seventeen of 34 cases (50%) of urothelial carcinoma showed no or weak expression of high molecular weight cytokeratin in the tumour cells. The other 17 cases (50%) of urothelial carcinoma showed strong expression of high molecular weight cytokeratin in the tumour cells. Fourteen of 34 cases (41%) showed negative or weak expression of p63 in tumour cells. Twenty of 34 cases (59%) showed strong expression of p63 in tumour cells. In the 14 of 34 cases (41%) and 17 of 34 cases (50%) which showed negative/weak expression of p63 and high molecular weight cytokeratin, respectively, in the tumour cells, the positive staining of the basal cells by p63 and high molecular weight cytokeratin in the benign prostatic glands and acini or those colonised by urothelial carcinoma, aided in the distinction from urothelial carcinoma with prostatic stromal invasion. In the remaining 20 of 34 cases (59%) and 17 of 34 cases (50%) in which the tumour cells showed strong expression of p63 and high molecular weight cytokeratin, respectively, larger malignant tumour cells and smaller benign basal cells of the prostatic glands and acini were highlighted with these markers, and were easily distinguishable. CONCLUSION Our study suggests that p63 and high molecular weight cytokeratin may be utilised in the distinction between urothelial carcinoma with prostatic stromal invasion and urothelial carcinoma with colonisation of prostatic ducts and acini.

Abstract
Mucosal spreading of urothelial tumors to the seminal vesicles is very rare. We experienced a case of mucosal involvement of the seminal vesicles by a bladder tumor in a 72-year-old man. The patient had a history of transurethral resection for invasive urothelial carcinoma of the bladder 8 years previously. Radical cystoprostatectomy was performed owing to recurrent and multiple urothelial carcinoma in situ. Microscopically, the urothelial carcinoma in situ was throughout the mucosa of the urinary bladder, both ureters, the prostate, and the left seminal vesicle. To date, the implication of mucosal involvement of the seminal vesicles by urothelial carcinoma is unclear. However, careful microscopic examination is needed to avoid an erroneous diagnosis.

Abstract
The urothelial carcinoma of the prostate is an entity which is necessary to recognize. The infiltration of the prostatic stroma is a major prognostic factor. The 2009 pTNM classification distinguish carcinoma in situ of the urethra with involvement of prostatic acini (pT2) from direct invasion of prostatic stroma through outside involvement (pT4). In case of non metastatic muscle invasive bladder cancer with major lymphatic invasion, the standard treatment remains neoadjuvant chemotherapy followed by radical cystectomy and extended lymphadenectomy. Only some patients can hope a complete response after neoadjuvant chemotherapy. For these responders, we can sometimes discuss, at an individual level, a bladder conservative strategy with an intensive surveillance.

Abstract
OBJECTIVE To investigate the prognostic significance of prostatic involvement by bladder urothelial carcinoma using the new 2009 TNM staging system. METHODS From 1993 to 2008, 77 consecutive men who were clinically and/or pathologically diagnosed with bladder cancer underwent radical cystectomy. Patients were classified into several groups, according to the presence, extent and invading pathway of prostatic involvement by urothelial carcinoma, whether there was stromal or non-stromal involvement, and whether there was contiguous or non-contiguous involvement. Cause-specific survivals were calculated in each group and they were compared. RESULTS Prostatic involvement was observed in 23 (30%) patients: 10 had non-contiguous non-stromal involvement, 5 had non-contiguous stromal involvement and 8 had contiguous stromal involvement. Patients with stromal involvement (both contiguous and non-contiguous) showed significantly shorter cause-specific survival compared with those without prostatic stromal involvement (P= 0.002). The survival of patients with contiguous prostatic stromal involvement was similar to that of patients with non-contiguous prostatic stromal involvement (P= 0.79). Multivariate analysis showed that prostatic stromal involvement (both contiguous and non-contiguous) (hazard ratio, 8.4; P< 0.001), lymph node involvement (hazard ratio, 4.4; P= 0.016) and perivesical fat involvement (hazard ratio, 3.8; P= 0.029) were predictive of cause-specific survival. CONCLUSIONS The depth of prostatic involvement has a significant impact on survival for patients with bladder urothelial carcinoma; however, whether its origin is contiguous or non-contiguous does not appear to be important.

Abstract
CIS is a flat, high-grade, non-invasive microscopic urothelial carcinoma. It is considered a precursor of invasive bladder cancer. CIS is classified as primary, secondary or concurrent, when occurred as isolated CIS without cuncurrent papillary tumors, or detected during the follow-up of patients with a previous papillary tumor, or finally in the presence of bladder neoplasm. BCG is widely established as the treatment of choice for CIS with a success rate of approximately 70%. BCG reduces the risk of progression of CIS into invasive carcinoma in 30 to 50% of cases. Direct and prolonged contact between the urothelium and BCG is a prerequisite for successful therapy. Discovery of CIS in the prostatic or membranous urethra represents an ominous sign. CIS may be present only in the epithelial lining of the prostatic urethra or in the ducts, or in the worst case it may be found in the prostatic tissue stroma. Urethral involvement by CIS is at high risk of tumor progression and development of metastases due to reduced thickness of lamina propria and absence of muscolaris mucosa. 83 patients, enrolled from 1/1996 to 12/2005 at our urological department with CIS: primary (focal and multifocal) in 25, secondary in 7 and cuncurrent in 51 (associated with T1bG3 cancer in 37 cases), and urethral CIS in 5 and conservatively treated by TUR and intravescical instillations of BCG, 4 developed after words only invasive cancer of the urethra in the absence of bladder involvement. In 2 cases cancer arised from the prostatic fossa after TURP, in 1 from membranous urethra and in the last from prostatic ducts. Among the 4 patients, 3 were treated by cystoprostatourethrectomy and Platinum-based chemotherapy, 1 refused surgical treatment. Two patients died for disseminated disease. 1 patient is alive at 60–month's follow-up. In the last patient cancer relapsed at 36–month's follow-up. We conclude that prostatic/urethral involvement during follow-up after successful intravesical treatment with BCG in CIS represents a high risk of developing invasive and incontrolled cancer. A careful watch is recommended in these patients.

Abstract
Prostate involvement is a major prognostic element in urothelium carcinoma staging after radical cystoprostatectomy (RCP) for muscle invasive bladder cancer. While appropriate pTNM stage is necessary for adequate treatment, no standard procedure exists up to now for macroscopic sampling of the prostate in RCP in daily practice. We therefore propose a protocol where examination of the whole prostatic urethra (PU) is possible, without using whole mount sections. From 2008 to June 2009, RCP were sampled according to a macroscopic protocol permitting the whole length and the underlying stroma of PU to be visualized. Data were compared with our series or RCP from 2000-2007, when the PU was evaluated with a more simple protocol. One hundred and one specimens were examined between 2000-2007, 25 until June 2009. In the latter series, we found pT4 bladder cancer in 36% versus 21%, Cis in the PU in 28% versus 14%, and additional prostate cancer was seen in 44% compared with 13% (p = 0.0004) in the 2008-2009 group versus the 2000-2007 group, respectively. Our proposed protocol better detects prostate involvement by bladder cancer, therefore providing a better final stage of the patients. We propose a macroscopic protocol where the whole PU and the underlying stroma can be examined without the use of whole mount sections. Data are similar to those published in the recent literature, where whole mount sections were used. This protocol also permits better detection of concomitant prostate carcinomas.

Abstract
OBJECTIVES To prospectively evaluate the incidence of transitional cell carcinoma (TCC) in the prostatic urethra and prostate in the cystoprostatectomy specimen, investigate characteristics of bladder tumours in relation to the risk of involvement of the prostatic urethra and prostate and examine the sensitivity of preoperative loop biopsies from the prostatic urethra. MATERIAL AND METHODS Preoperatively, patients were investigated with cold cup biopsies from the bladder and transurethral loop biopsies from the bladder neck to the verumontanum. The prostate and bladder neck were submitted to sagittal whole-mount pathological analysis. RESULTS The incidence of TCC in the prostatic urethra and prostate in the cystoprostatectomy specimen was 29% (50/175 patients). Age, previous bacillus Calmette-Guérin treatment, carcinoma in situ (Cis) in the cold cup mapping biopsies and tumour grade were not associated with the risk of TCC in the prostatic urethra/prostate. Cis, multifocal Cis (> or = 2 locations) and tumour location in the trigone were significantly more common in cystectomy specimens with TCC in the prostatic urethra and prostate: 21/50 (42%) vs 32/125 (26%), p=0.045; 20/50 (40%) vs 27/125 (22%), p=0.023; and 20/50 (40%) vs 26/125 (21%), p=0.01, respectively. Preoperative resectional biopsies from the prostatic urethra in the 154 patients analysed identified 31/47 (66%) of patients with TCC in the prostatic urethra/prostate, with a specificity of 89%. The detection of stromal-invasive and non-stromal involvement was similar: 66% and 65%, respectively. CONCLUSIONS The incidence of TCC in the prostatic urethra and prostate was 29% (50/175) in the cystoprostatectomy specimen. Preoperative biopsies from the prostatic urethra identified 66% of patients with such tumour growth. Our findings suggest that preoperative cold cup mapping biopsies of the bladder for detection of Cis add little extra information with regard to the risk of TCC in the prostatic urethra and prostate.

Abstract
OBJECTIVES To ascertain which variables of bladder urothelial carcinoma (UC) might be useful in predicting either UC involving the prostate (UCP) or incidental prostate adenocarcinoma in radical cystoprostatectomy specimens. METHODS The bladder and whole-mount prostate sections of 248 radical cystoprostatectomy specimens were reviewed. Stepwise discriminant analysis was used to predict UCP or incidental prostate adenocarcinoma. RESULTS UCP was present in 94 patients (37.9%). UC originated from the prostatic urethra and periurethral ducts in 78 (31.45%), and isolated direct extension of UC from the bladder was present in 16 patients (6.45%). The periurethral ducts coexisted with direct extension of bladder UC in 11 patients (4.4%). Prostate adenocarcinoma was identified in 123 patients (49.6%). Carcinoma in situ and high-grade urothelial papillary carcinoma were seen in 8 (3.2%) and 5 (2.0%) patients, respectively. In 57 (23%), 64 (25.8%), and 87 (35.1%) patients, UC had invaded the subepithelial connective tissue, muscularis propria, and perivesical tissue, respectively. UC was multifocal in 53 patients (21.4%). The tumor was in the trigone and bladder neck in 160 patients (64.5%). Of the 248 patients, 98 (39.5%) had a history of recurrence. Stepwise discriminant analysis selected 3 variables of bladder UC (previous recurrence and location and number of foci) and correctly predicted the group in 72.2% of patients without and with UCP. Discriminant analysis selected 2 variables of bladder UC (focality and previous recurrence) and correctly predicted the group in 57.7% of patients without and with prostate adenocarcinoma. CONCLUSIONS Our approach can identify bladder UC variables that could guide urologists in the selection of the most appropriate surgical procedure.

Abstract
Significant progress has been made in the standardization of bladder neoplasm classification and reporting. Accurate staging using the American Joint Committee on Cancer/International Union Against Cancer (AJCC/UICC) TNM system is essential for patient management, and has been reinforced by clinical evidence in recent years. It is now recognized that 'superficial' bladder carcinomas are a heterogenous group of tumors with diverse biological and clinical manifestations. The term 'superficial,' therefore, is no longer used for bladder tumor nomenclature. Recognition of diagnostic pitfalls associated with lamina propria invasion is critical for the evaluation of bladder tumor specimens. Neither the 1973 nor the 2004 WHO grading system appears to be useful for predicting the clinical outcome of invasive urothelial carcinoma. This review will discuss recent progress and controversial issues on the staging and substaging of bladder carcinomas. Essential elements for handling and reporting of bladder tumor specimens will also be discussed.

Abstract
OBJECTIVE To examine the risk factors for urothelial carcinoma (UC) involvement of the prostate in patients undergoing radical cystoprostatectomy (RCP) for bladder cancer, as such involvement has both prognostic and therapeutic implications. PATIENTS AND METHODS We examined 308 consecutive men from 1998 to 2005 who had RCP for UC of the bladder, with whole-mount processing of their prostate. Prostatic involvement was categorized by site of origin (the bladder or the prostatic urethra) and, in the case of prostatic urethral origin, by depth of invasion, i.e. dysplasia/carcinoma in situ (CIS), involving the prostatic urethra, prostatic ductal invasion or prostatic stromal invasion. The impact of pathological characteristics was evaluated. RESULTS In all, 121 (39.3%) patients had some form of urothelial involvement of the prostate, of whom 59 (48.8%) had dysplasia/CIS of the prostatic urethra, 20 (16.5%) had ductal involvement and 32 (26.4%) had stromal involvement. Multivariate analysis showed that bladder CIS (odds ratio 2.0, 95% confidence interval, 1.2-3.6, P = 0.012) and trigonal involvement of bladder tumours (2.0, 1.1-3.7, P = 0.028) were independent risk factors for urothelial involvement of the prostate. CONCLUSION There was prostatic involvement with UC in nearly 40% of patients undergoing RCP. In this study CIS and trigonal involvement were independent predictors of risk, but were not adequate enough to accurately identify most patients who have UC within their prostate; further prospective studies are needed to more accurately predict risk factors and depth of invasion.

Abstract
The prostate is commonly involved by transitional cell carcinoma (TCC) in patients with bladder cancer. A number of clinicopathologic factors including multifocal carcinoma in situ, tumor location, and tumor stage are associated with prostatic TCC (pTCC). In addition, the manner and extent of pathologic examination also makes a significant difference in the detection rate. Distinct patterns and extent of pTCC have been described and are associated with pathologic stage of the primary bladder tumor as well as prognosis. Preoperative transurethral biopsy of the prostatic urethra is a sensitive and accurate method to detect pTCC and is helpful for surgical planning. Given the high incidence of pTCC and prostatic adenocarcinoma, radical cystoprostatectomy is the treatment of choice for loco-regional control for patients with T4a disease. Further studies are necessary to establish the role of neoadjuvant and adjuvant therapy for patient with prostatic stroma invasion.
