Abstract
OBJECTIVE To determine the effectiveness and adverse effects of urethrectomy alone or as part of multimodal therapy (MMT). METHODS A comprehensive search was conducted across MEDLINE (OVID), EMBASE, LILACS and the Cochrane Central Register of Controlled Trials (CENTRAL) databases, from their inception to the present date. The study cohort comprised individuals aged 16 years and older diagnosed with urethral tumours at any stage who underwent either isolated urethrectomy or urethrectomy as an integral component of MMT. RESULTS Ninety-two studies comprising 25 480 patients met the inclusion criteria. Surgical outcomes for urethral cancer vary considerably, with 5-year overall survival (OS) ranging from 10% to 68% based on disease extent, approach, and gender. Radiotherapy (RT) alone provides 5-year OS of approximately 40%. Combined regimens provide better outcomes compared to single modalities, including reduced recurrence and enhanced survival. However, trimodal therapy showed survival benefits only for urothelial subtypes, indicating the need to tailor management according to cancer type. MMT with neoadjuvant chemotherapy prior to surgery demonstrated the most consistent survival gains. CONCLUSIONS The management of urethral cancer demands a nuanced, personalised approach, accounting for factors such as tumour location, sex, and tumour stage. MMT combining surgery, chemotherapy and RT has shown the ability to enhance outcomes in advanced disease. More extensive collaborative studies through specialised centres are imperative to advance evidence-based protocols and refine treatment in order to improve survival.

Abstract
BACKGROUND It is unknown whether married status may be associated with lower cancer-specific mortality (CSM) rates in primary urethral carcinoma (PUC) patients. To test for differences in CSM rates, according to marital status, we relied on the Surveillance, Epidemiology, and End Results (SEER) database 2000-2020. METHODS Patient (age, sex, race/ethnicity, marital status), tumor (stage, histology), and treatment (surgery, systemic therapy) characteristics of PUC patients were tabulated. Then, Kaplan-Meier plots, as well as univariable and multivariable Cox regression (MCR) models tested for differences in CSM rates according to marital status in overall cohort and then in sex-specific subgroup analyses. RESULTS Of all 1,571 PUC patients, 70% were male vs. 30% female. Females were statistically significantly younger (68 vs. 73 years), more frequently unmarried (54 vs. 28%), non-Caucasian (43 vs. 24%), more frequently harbored T3-4N0M0 (39 vs. 18%) and less frequently T1-2N0M0 (53 vs. 69%) or TanyN1-2M0/TanyNanyM1 (8 vs. 13%), relative to males. Moreover, we recorded differences in histotype proportions in females vs. males (urothelial 30 vs. 64%; squamous 24 vs. 22%; adenocarcinoma 36 vs. 7%; others 10 vs. 6%) and surgical treatment (none 22 vs. 17%; excisional biopsy 22 vs. 36%; partial urethrectomy 14 vs. 16%; radical urethrectomy 42 vs. 31%). In MCR models focusing on the entire cohort, married status independently predicted lower CSM (hazard ratio [HR]:0.82; P = 0.02). Similarly, in MCR models focusing on females, married status independently predicted lower CSM (HR:0.73; P = 0.03). Conversely, in MCR models focusing on males, married status failed to independently predict lower CSM (HR:0.89; P = 0.3). CONCLUSIONS Married status was associated with lower CSM in PUC patients. However, this benefit applies to female PUC patients, but not to their male counterparts.

Abstract
Primary female urethral carcinoma (PUC-F) accounts for less than 1% of all genitourinary malignancies and comprises a histologically diverse group of tumors that are usually associated with poor prognosis. The carcinomas documented at this site include adenocarcinoma (clear cell adenocarcinoma, columnar cell carcinoma, and Skene gland adenocarcinoma), urothelial carcinoma (UCa), and squamous cell carcinoma (SCC). Recent studies have shown adenocarcinomas to be the most common type of primary urethral carcinoma in females. As most of the urethral carcinomas morphologically resemble carcinomas arising from surrounding pelvic organs or metastases, these should be ruled out before making the diagnosis of PUC-F. These tumors are currently staged according to the 8th edition of the American Joint Committee on Cancer (AJCC) staging system. However, the AJCC system has limitations, including the staging of tumors involving the anterior wall of the urethra. Staging systems like the recently proposed histology-based female urethral carcinoma staging system (UCS) takes into account the unique histological landmarks of the female urethra to better stratify pT2 and pT3 tumors into prognostic groups, that correlate with clinical outcomes including recurrence rates, disease-specific survival and overall survival. Further larger multi-institutional cohorts are however required to validate the results of this staging system. There is very limited information regarding the molecular profiling of PUC-F. Thirty-one percent of clear cell adenocarcinomas have been reported to show PIK3CA alterations, whereas 15% of adenocarcinomas show PTEN mutations. Higher tumor mutational burden and PD-L1 staining have been reported in UCa and SCC. Although multimodality treatment is usually recommended in locally advanced and metastatic disease, the role of immunotherapy and targeted therapy is promising in select PUC-F cases.

Management of Primary Female Urethral Adenocarcinoma: Two Rare Case Reports and Literature Review. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59010109.

Abstract
Primary urethral adenocarcinoma in females is an extremely rare malignancy with unclear origin and only a few retrospective cases have been reported. The controversy continues to exist over the origin of primary urethral adenocarcinoma from periurethral glands (which include the Skene's glands), urethritis glandularis or intestinal metaplasia. Herein, we report one case of a 49-year-old female with distal urethral adenocarcinoma who presented with obstructive voiding. Abdominal and pelvic CT scans and chest radiology were unremarkable. Biopsy of the mass confirmed urethral adenocarcinoma. The patient underwent partial ureterectomy and was disease-free at the 2-years follow-up period. We also present another extremely rare case of primary urethral adenocarcinoma with mucinous features in a 58-year-old female who initially complained of external urethral orifice itching with painless urethral bleeding and was treated with local excision. The patient has not received any neoadjuvant or adjuvant therapy, and experienced tumor recurrence, inguinal lymph nodes metastasis, and even local iliopsoas metastasis during over 10-years follow-up. In conclusion, our current study emphasizes the importance of imaging studies and biopsy in making an accurate preoperative diagnosis of this rare disease, and further highlights the role of multimodal therapy. A combination of radiotherapy, chemotherapy and surgery is recommended for the optimal local and distant disease control. Moreover, better medical compliance and regular follow-up are required in these patients.

Abstract
INTRODUCTION The aim of the study was to examine cancer-specific mortality (CSM) of unconventional urethral cancers. METHODS Within the SEER (2004-2016) database, we analyzed CSM of 165 patients with unconventional urethral-cancer histology. Kaplan-Meier plots were used to test the effect of unconventional histologies in urethral cancer on CSM. RESULTS Of 165 eligible patients, the Mullerian type accounted for 55 (33.3%) versus melanocytic (26.7%) versus neuroendocrine 25 (15.2%) versus lymphoma 22 (13.3%) versus mesenchymal/sarcoma 15 (9.1%) versus spindle cell 4 (2.1%) patients. Median age at diagnosis was 81 years in spindle cell, 75 in melanocytic, 74 in neuroendocrine and mesenchymal/sarcoma, 67 in lymphoma, and 62 years Mullerian type (p < 0.001). Of all, 116 (70.3%) were female. The Mullerian type exhibited the highest female ratio (96.4%) versus the lowest female ratio in neuroendocrine (24.0%). The Mullerian type was most frequent in African-American females. In Caucasian females, the melanocytic type was most frequent (49.1%). In African-American (38.9%) and Caucasian males (33.3%), neuroendocrine histology was most frequent. Three-year CSM was, respectively, 27.5%, 23.1% 22.3%, 20.5%, and 16.1% for melanocytic, mesenchymal/sarcoma, Mullerian type, neuroendocrine, and lymphoma histology. Median cancer-specific survival was 106 versus 10 months for combined nonmetastatic versus metastatic nonconventional histologies. CONCLUSION Important age, sex, racial/ethnic group distribution, and survival differences exist between each unconventional urethral-cancer histological subtypes.

Abstract
Urethral and periurethral masses in women include both benign and malignant entities that can be difficult to clinically differentiate. Primary urethral carcinoma is rare and the optimal treatment modality may vary depending on the stage at presentation. Because cancer-free survival is poor, clinicians shouldhave a high index of suspicion when evaluating a urethral mass. Some benign-appearing urethral masses may be safely observed. Surgical resection is an effective option that should be used based on patient preference and symptoms, and for suspicious lesions.

Abstract
BACKGROUND Carcinoma of the urethra (UrthCa) is an uncommon Genitourinary (GU) malignancy that can progress to advanced metastatic disease. METHODS One hundred twenty-seven metastatic UrthCa underwent hybrid capture-based comprehensive genomic profiling to evaluate all classes of genomic alterations (GA). Tumor mutational burden was determined on up to 1.1 Mbp of sequenced DNA, and microsatellite instability was determined on 114 loci. PD-L1 expression was determined by IHC (Dako 22C3). RESULTS Forty-nine (39%) urothelial (UrthUC), 31 (24%) squamous (UrthSCC), 24 (19%) adenocarcinomas NOS (UrthAC), and 12 (9%) clear cell (UrthCC) were evaluated. UrthUC and UrthSCC are more common in men; UrthAC and UrthCC are more common in women. Ages were similar in all 4 groups. GA in PIK3CA were the most frequent potentially targetable GA; mTOR pathway GA in PTEN were also identified. GA in other potentially targetable genes were also identified including ERBB2 (6% in UrthUC, 3% in UrthSCC, and 12% in UrthAC), FGFR1-3 (3% in UrthSCC), BRAF (3% in UrthAC), PTCH1 (8% in UrthCC), and MET (8% in UrthCC). Possibly reflecting their higher GA/tumor status, potential for immunotherapy benefit associated with higher tumor mutational burden and PD-L1 staining levels were seen in UrthUC and UrthSCC compared to UrthAC and UrthCC. Microsatellite instability high status was absent throughout. CONCLUSIONS Comprehensive genomic profiling reveals GA that may be predictive of both targeted and immunotherapy benefit in patients with advanced UrthCa and that could potentially be used in future adjuvant, neoadjuvant, and metastatic disease trials.

Abstract
PURPOSE We assessed contemporary incidence rates and trends of primary urethral cancer. METHODS We identified urethral cancer patients within Surveillance, Epidemiology and End Results registry (SEER, 2004-2016). Age-standardized incidence rates per 1,000,000 (ASR) were calculated. Log linear regression analyses were used to compute average annual percent change (AAPC). RESULTS From 2004 to 2016, 1907 patients with urethral cancer were diagnosed (ASR 1.69; AAPC: -0.98%, p = 0.3). ASR rates were higher in males than in females (2.70 vs. 0.55), respectively and did not change over the time (both p = 0.3). Highest incidence rates were recorded in respectively ≥75 (0.77), 55-74 (0.71) and ≤54 (0.19) years of age categories, in that order. African Americans exhibited highest incidence rate (3.33) followed by Caucasians (1.72), other race groups (1.57) and Hispanics (1.57), in that order. A significant decrease occurred over time in Hispanics, but not in other race groups. In African Americans, male and female sex-stratified incidence rates were higher than in any other race group. Urothelial histological subtype exhibited highest incidence rate (0.92), followed by squamous cell carcinoma (0.41), adenocarcinoma (0.29) and other histologies (0.20). In stage stratified analyses, T1N0M0 stage exhibited highest incidence rate. However, it decreased over time (-3.00%, p = 0.02) in favor of T1-4N1-2M0 stage (+ 2.11%, p = 0.02). CONCLUSION Urethral cancer is rare. Its incidence rates are highest in males, elderly patients, African Americans and in urothelial histological subtype. Most urethral cancer cases are T1N0M0, but over time, the incidence of T1N0M0 decreased in favor of T1-4N1-2M0.

Abstract
Background To test the effect of variant histology relative to urothelial histology on stage at presentation, cancer specific mortality (CSM), and overall mortality (OM) after chemotherapy use, in urethral cancer. Materials and Methods Within the Surveillance, Epidemiology and End Results (2004-2016) database, we identified 1,907 primary variant histology urethral cancer patients. Kaplan-Meier plots, Cox regression analyses, cumulative incidence-plots, multivariable competing-risks regression models and propensity score matching for patient and tumor characteristics were used. Results Of 1,907 eligible urethral cancer patients, urothelial histology affected 1,009 (52.9%) vs. squamous cell carcinoma (SCC) 455 (23.6%) vs. adenocarcinoma 278 (14.6%) vs. other histology 165 (8.7%) patients. Urothelial histological patients exhibited lower stages at presentation than SCC, adenocarcinoma or other histology patients. In urothelial histology patients, five-year CSM was 23.5% vs. 34.4% in SCC [Hazard Ratio (HR) 1.57] vs. 40.7% in adenocarcinoma (HR 1.69) vs. 43.4% in other histology (HR 1.99, p < 0.001). After matching in multivariate competing-risks regression models, variant histology exhibited 1.35-fold higher CSM than urothelial. Finally, in metastatic urethral cancer, lower OM was recorded after chemotherapy in general, including metastatic adenocarcinoma and other variant histology subtypes, except metastatic SCC. Conclusion Adenocarcinoma, SCC and other histology subtypes affect fewer patients than urothelial histology. Presence of variant histology results in higher CSM. Finally, chemotherapy for metastatic urethral cancer improves survival in adenocarcinoma and other variant histology subtypes, but not in SCC.

Abstract
OBJECTIVE To test the effect of race/ethnicity on histological subtype, stage at presentation, and cancer specific mortality (CSM) in urethral cancer patients. MATERIAL AND METHODS Stratified analyses (Surveillance, Epidemiology and End Results [2004-2016]) tested the effect of race/ethnicity on histology and stage. Cumulative incidence-plots and multivariable competing-risks regression models (CRR), addressed CSM, after matching for TNM-stage, histology, age, and gender. RESULTS Of 1,904 urethral cancer patients, 71% were Caucasian, 16% African American, 7% Hispanic and 5% other. African Americans were younger (66 years) than Caucasians (73 years) and Hispanics (74 years). In African Americans, adenocarcinoma (25%) and squamous cell carcinoma (SCC; 29%) were more frequent than in Caucasians (12% and 23%) or Hispanics (15% and 20%). African Americans with adenocarcinoma exhibited higher stage than other adenocarcinoma patients. In CRR, African Americans (35%) and Hispanics (29%) exhibited highest and second highest 3-year CSM, even after matching. After further multivariable adjustment of matched CRRs, CSM was higher in Hispanics (HR: 1.93, P= 0.03) and in African Americans (Hazard ratio 1.35, P= 0.07), relative to Caucasians. CONCLUSION Race/ethnicity impacts important differences on urethral cancer patients. African American race/ethnicity predisposes to higher rate of SCC and adenocarcinoma. Moreover, African Americans are younger and present with higher stage at diagnoses. Finally, even after most detailed matching for stage, age, gender, and adjustment for treatment and systemic therapy and socioeconomic status, African Americans and Hispanics exhibit higher CSM than Caucasians.

Abstract
CONTEXT Primary urethral carcinoma (PUC) is a rare cancer accounting for <1% of all genitourinary malignancies. OBJECTIVE To provide updated practical recommendations for the diagnosis and management of PUC. EVIDENCE ACQUISITION A systematic search interrogating Ovid (Medline), EMBASE, and the Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews was performed. EVIDENCE SYNTHESIS Urothelial carcinoma of the urethra is the predominant histological type of PUC (54-65%), followed by squamous cell carcinoma (16-22%) and adenocarcinoma (10-16%). Diagnosis of PUC depends on urethrocystoscopy with biopsy and urinary cytology. Pathological staging and grading are based on the tumour, node, metastasis (TNM) classification and the 2016 World Health Organization grading systems. Local tumour extent and regional lymph nodes are assessed by magnetic resonance imaging, and the presence of distant metastases is assessed by computed tomography of the thorax/abdomen and pelvis. For all patients with localised distal tumours (≤T2N0M0), partial urethrectomy or urethra-sparing surgery is a valid treatment option, provided that negative intraoperative surgical margins can be achieved. Prostatic Ta-Tis-T1 PUC can be treated with repeat transurethral resection of the prostate and bacillus Calmette-Guérin. In prostatic or proximal ≥ T2N0 disease, neoadjuvant cisplatin-based chemotherapy should be considered prior to radical surgery. All patients with locally advanced disease (≥T3N0-2M0) should be discussed within a multidisciplinary team. In men with locally advanced squamous cell carcinoma, curative radiotherapy combined with radiosensitising chemotherapy can be offered for definitive treatment and genital preservation. In patients with local urethral recurrence, salvage surgery or radiotherapy can be offered. For patients with distant metastatic disease, systemic therapy based on tumour characteristics can be evaluated. CONCLUSIONS These updated European Association of Urology guidelines provide up-to-date guidance for the contemporary diagnosis and management of patients with suspected PUC. PATIENT SUMMARY Primary urethral carcinoma (PUC) is a very rare, but aggressive disease. These updated European Association of Urology guidelines provide evidence-based guidance for clinicians treating patients with PUC.

Abstract
BACKGROUND Our aim was to identify the independent prognostic factors in patients with primary urethral carcinoma (PUC) and to predict their overall survival (OS) and cancer-specific survival (CSS) at 3, 5, and 8 years. METHODS Patients with PUC identified in the Surveillance, Epidemiology, and End Results (SEER) database were divided into training and validation cohorts. Nomograms were constructed based on the results of Cox regression analysis. The predictive performance of each nomogram was evaluated using the consistency index (C-index), the area under the receiver operating characteristics curve (AUC), and calibration plots. Decision-curve analysis (DCA) was used to test the clinical value of the predictive models. RESULTS Our study screened 822 patients with PUC. Multivariate analysis showed that the age at diagnosis, race, histology, American Joint Committee on Cancer (AJCC) stage, and surgery status were independent prognostic factors for CSS and age at diagnosis, race, histology, AJCC stage, surgery status, and chemotherapy for OS (all P < 0.05). We used these prognostic factors to construct nomograms. The C-indexes for OS and CSS were 0.713 and 0.741 in training cohorts and 0.714 and 0.738 in validation cohorts, respectively. The AUC and calibration plots demonstrated the good performance of both nomograms. The DCA indicated the presence of clinical net benefits in both the training and validation cohorts. CONCLUSION We developed and validated nomograms for predicting OS and CSS in patients with PUC, which can help clinicians make treatment decisions.

Abstract
Patients with localized urethral melanoma have a high risk of recurrence and poor disease-specific survival. Multi-disciplinary approach including surgery, radiation therapy, and chemotherapy/immunotherapy is needed to maximize survival. Current research efforts include investigation of novel tyrosine kinases as well as the combination of targeted therapies with immunotherapies in this population. Combinations may provide a synergistic effect to overcome various obstacles to disease response.

Abstract
Purpose Urethral carcinoma (UC), as a rare tumor, is not widely studied. There have been no systematic studies of rare pathological types of UC. We conducted this study to further investigate rare pathological types of primary urethral carcinoma (PUC). Materials and methods We used the population-based Surveillance, Epidemiology, and End Results (SEER) database to evaluate prognostic factors in rare pathological types of PUC. From 1978 to 2015, 2,651 and 257 cases were identified in the SEER database as common and rare pathological types of PUC, respectively. Overall and cancer-specific survival (CSS) times were computed using the Kaplan–Meier method, and the Cox proportional hazards analysis was used to evaluate patient age at diagnosis, gender, race, and TNM stage. Results The median overall survival (OS) rates were 36 and 59 months for rare and common pathological groups, respectively, and their respective 10-year OS rates were 31.9% and 42.4%, respectively. The median CSS rate was 61 months for the rare pathological group. Through multivariate analysis, it was found that age, race, T stage, and M stage were independent prognostic risk factors for rare pathological type of urethral cancer. In the age group, the HR ratio of patients aged older than 60 years and younger or equal to 60 years was 2.778 (P<0.001). The HR ratio of other races to Whites was 1.444 (P=0.040). In TNM staging, the HR ratio between T3–T4 and Ta–T2 was 2.386 (P=0.046), and the HR value of M1 and M0 was 5.847 (P<0.001). Conclusion Age, race, T stage, and M stage were predictive of OS and CSS in rare pathological PUC.

Abstract
Objectives Primary urethral carcinoma (PUC) is rare, accounting for <1% of genitourinary malignancies. Current knowledge regarding is founded upon tertiary care centers reporting their experiences. We aim to identify factors predictive of outcomes using a nationwide registry database. Materials and Methods The Surveillance, Epidemiology, and End Results-18 registries database was queried for cases of PUC ranging between 2004 and 2010. To identify PUC cases, ICD-O site code C68.0 was used as a filter, hence identifying PUC with histologic subtypes including urothelial carcinoma (UC), squamous cell carcinoma (SCC), and adenocarcinoma (AC). Tumor characteristics were compared using log-rank analysis, and survival outcomes were compared using Cox proportional hazards models. Results A total of 419 PUC cases were identified, 250 (59.7%) male and 169 (40.3%) female patients. The most common histology in men was UC (134, 53.6%), followed by SCC (87, 34.8%) and AC (29, 11.6%). The most common histology in women was AC (79, 46.7%), followed by SCC (43, 25.4%) and UC (42, 24.9%). Log-rank analysis illustrated significant difference in cancer-specific survival (CSS) for T-stage, N-stage, M-stage, and stage of PUC with all histological variants combined (P < 0.001). Multivariate Cox proportional hazards model demonstrated that stage and age were significant for survival, with a risk ratio of 1.033 (95% confidence interval [CI], 1.020-1.046)/year of increased age (P < 0.001) and 3.71 (95% CI, 2.72-5.05) for patients with regional or distant spread. Conclusions Knowledge of patient and tumor characteristics that influences survival is paramount in dictating management. The present study illustrates that age and stage are factors significantly associated with CSS in PUC.

Abstract
Cancers of the lower urinary tract can arise from the bladder, urachus or urethra. Urothelial carcinoma of the bladder (UCB) is the most common of these. The presentation of bladder, urachal and urethral cancers can differ but many result in hematuria as an initial indication. The diagnosis and staging of these cancers often necessitate radiologic imaging often in the form of cross-section CT urography or MR urography. The following article reviews the specific nature of lower tract cancers and their imaging.

Abstract
Purpose To analyze the Surveillance, Epidemiology, and End Results (SEER) database to determine the effects of sex and prognostic factors on the survival of patients with primary urethral carcinoma (PUC). Materials and methods We selected 453 patients diagnosed with PUC from 2004 to 2013 from the SEER database. Statistical analysis was used to identify sex-specific differences associated with tumor characteristics and cancer-specific survival (CSS) and overall survival (OS). Results Compared with men, there was a higher proportion of black women, more negative lymph-node status, higher American Joint Committee on Cancer (AJCC) stage, more advanced T3 stage, more with adenocarcinoma (Ac), and fewer with squamous cell carcinoma (SCC) or transitional cell carcinoma (TCC). Among women, black race and M1 stage were associated with shorter CSS and OS, respectively. In addition, surgery was associated with longer OS in women. Among men, AJCC III and IV and M1 stages were associated with shorter CSS and OS. In addition, age >75 years associated with shorter OS in men. Conclusion Black race was associated with shorter OS and CSS of women, and surgery was associated with longer OS of women. Among men, AJCC stage III and IV were associated with shorter OS and CSS. Age >75 years was associated with shorter OS in men only. Women with Ac experienced poor CSS compared with men. Men with TCC experienced worse CSS compared with those with Ac or SCC.

Abstract
BACKGROUND Urethral cancer is a rare malignancy, representing <1% of all malignancies. Optimal management, due to its rarity, presents as a treatment dilemma for physicians. There is a lack of consensus regarding treatment as large randomized trials cannot be performed; thus, optimal management decisions rely on study of retrospective cases. This is a review of our institutional experience with urethral cancer treated with various treatment modalities. METHODS A retrospective chart review was performed on 31 patients treated for primary cancer of the urethra from 1958 to 2008. The patients were stratified by sex, histologic type, stage, date of diagnosis, type of treatment, and last follow-up. Early stage cases were designated as Tis-T2N0M0 and advanced cases were designated as T3-4, N+ or M+. Analysis was performed based on clinical stage, treatment modalities and outcomes. RESULTS Fourteen early stage cases and 17 advanced stage cases of urethral cancer were analyzed. The majority of early stage cases occurred in men (M:F=8:6) and the majority of advanced stage cases occurred in women (M:F=5:12). The most common histology was squamous cell carcinoma for both early and advanced stage cases. Surgery was the preferred modality of treatment for early stage cases (surgery used in 13 cases vs. chemo/radiotherapy used in 1 case) while for advanced cases, radiation ±chemotherapy was commonly used. Overall survival for this series was 45% at mean follow-up of 7 years. Eight of the 14 cases of early stage cancer remained disease free at last follow-up. Comparatively, only 5 of 17 with advanced cancers had no apparent disease at last follow-up. All but one of those patients were treated with combined modality therapy. CONCLUSIONS Patients with early stage urethral cancers do well with single modality therapy, whereas patients who present with advanced cancers may benefit from combined modality therapy. More extensive study is required to recommend a particular treatment protocol. However, in this rare malignancy, institutional experiences provide the best evidence currently due to the lack of multi-institutional trials.

Clear Cell Adenocarcinoma of the Urethra in Women: Distinctive MRI Findings for Differentiation From Nonadenocarcinoma and Non-Clear Cell Adenocarcinoma of the Urethra. AJR Am J Roentgenol 2017; 208:805-811. [PMID: 28140610 DOI: 10.2214/ajr.16.16929] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/13/2022]
Abstract
OBJECTIVE The purpose of this study is to evaluate the MRI findings differentiating clear cell adenocarcinoma of the urethra (CCAU) from nonadenocarcinoma of the urethra (NACU) and non-clear cell adenocarcinoma of the urethra (NCCAU) in women. MATERIALS AND METHODS Six women with pathologically proven CCAU, six women with pathologically confirmed NACU (two squamous cell carcinomas and four transitional cell carcinomas), and nine women with NCCAU underwent preoperative MRI. The MRI findings for CCAU, NACU, and NCCAU were reviewed by a radiologist who was blinded to the histopathologic findings and were compared using the Mann-Whitney U test and the Fisher exact test. RESULTS CCAU was shorter in height than NACU (3.4 cm vs 5.5 cm; p = 0.020) and also had a smaller height-to-width ratio than NACU (0.85 vs 1.51; p < 0.001) and NCCAU (0.85 vs 1.48; p = 0.002). The proportion of preserved urethra in CCAU (67%) was larger than that in either NACU (9%; p < 0.001) or NCCAU (22%; p < 0.001). All cases of CCAU originated within a diverticulum, whereas none of the cases of NACU and only one NCCAU originated in a diverticulum. Intratumoral septation was more frequently observed in CCAU (100%) than in NACU (16.6%; p = 0.015) or NCCAU (11.1%; p = 0.001). CONCLUSION MRI findings for CCAU were significantly distinctive, compared with findings for NACU and NCCAU. All cases of CCAU were associated with a urethral diverticulum, and CCAU had a lower height-to-width ratio, more frequent intratumoral septation, and greater preservation of normal urethra than did NACU and NCCAU.

Abstract
OBJECTIVE To identify prognostic and treatment factors for primary urethral cancer using a nationwide database. MATERIALS AND METHODS The National Cancer Database was queried for all cases of primary urethral cancer from 2004 to 2013. Patients with other cancer diagnoses, metastasis, or diagnosis on autopsy were excluded. Proportional hazards regression was used to identify independent predictors of overall survival in patients with primary urethral cancer. Because we hypothesized that predictors may covary by sex, we also performed regression analysis stratified by sex. RESULTS We identified 1268 men and 869 women with primary urethral cancer. Women tended to have more advanced tumors and adenocarcinoma histology. Median survival for the entire cohort was 49 months (43-55), with 5- and 10-year survival rates of 46% and 31%, respectively. On multivariate analysis, age, race, stage, grade, and Charlson comorbidity index were independent predictors of overall survival. Histology was not a predictor of overall survival in the combined model; however, adenocarcinoma in women increased hazards of death, whereas it decreased hazards of death in men when compared with squamous cell carcinoma. CONCLUSION Men and women with primary urethral cancer had significant differences in histology, grade, and nodal status. In addition to several expected disease-related factors, black race was associated with increased mortality for patients with primary urethral cancer.

Abstract
The aim of this study was to evaluate female urethral cancer (UCa) patients treated and followed-up during a time period spanning more than 20 yr at single institution in Korea. We reviewed medical records of 21 consecutive patients diagnosed with female UCa at our institution between 1991 and 2012. After exclusion of two patients due to undefined histology, we examined clinicopathological variables, as well as survival outcomes of 19 patients with female UCa. A Cox proportional hazards ratio model was used to identify significant predictors of prognosis according to variables. The median age at diagnosis was 59 yr, and the median follow-up duration was 87.0 months. The most common initial symptoms were voiding symptoms and blood spotting. The median tumor size was 3.4 cm, and 55% of patients had lesions involving the entire urethra. The most common histologic type was adenocarcinoma, and the second most common type was urothelial carcinoma. Fourteen patients underwent surgery, and 7 of these patients received adjuvant radiation or systemic chemotherapy. Eleven patients experienced tumor recurrence after primary therapy. Patients with high stage disease, advanced T stage (≥T3), and positive lymph nodes had worse survival outcomes compared to their counterparts. Particularly, lymph node positivity and advanced T stage were significant predictive factors for all survival outcomes. Tumor location was the only significant predictor for recurrence-free survival. Although our study included a small number of patients, it conveys valuable information about this rare female urologic malignancy in a Korean population.

Abstract
PURPOSE To evaluate risk factors for survival in a large international cohort of patients with primary urethral cancer (PUC). METHODS A series of 154 patients (109 men, 45 women) were diagnosed with PUC in ten referral centers between 1993 and 2012. Kaplan-Meier analysis with log-rank test was used to investigate various potential prognostic factors for recurrence-free (RFS) and overall survival (OS). Multivariate models were constructed to evaluate independent risk factors for recurrence and death. RESULTS Median age at definitive treatment was 66 years (IQR 58-76). Histology was urothelial carcinoma in 72 (47 %), squamous cell carcinoma in 46 (30 %), adenocarcinoma in 17 (11 %), and mixed and other histology in 11 (7 %) and nine (6 %), respectively. A high degree of concordance between clinical and pathologic nodal staging (cN+/cN0 vs. pN+/pN0; p < 0.001) was noted. For clinical nodal staging, the corresponding sensitivity, specificity, and overall accuracy for predicting pathologic nodal stage were 92.8, 92.3, and 92.4 %, respectively. In multivariable Cox-regression analysis for patients staged cM0 at initial diagnosis, RFS was significantly associated with clinical nodal stage (p < 0.001), tumor location (p < 0.001), and age (p = 0.001), whereas clinical nodal stage was the only independent predictor for OS (p = 0.026). CONCLUSIONS These data suggest that clinical nodal stage is a critical parameter for outcomes in PUC.

Abstract
Primary urethral carcinoma (PUC) is a rare malignancy accounting for <1% of genitourinary cancers, with a predilection for men and African-Americans. The sites and histology of urethral carcinoma vary by gender and anatomical location. Squamous cell carcinoma is most common among both genders but adenocarcinomas are noted in 15-35% of cases among women. Obstructive or irritative symptoms and haematuria are common modes of presentation. Clinical evaluation includes cystourethroscopy with biopsy and examination under anaesthesia. Magnetic resonance imaging provides a highly effective method to image the primary tumour while defıning the potential involvement of surrounding structures. Most tumours are localised, with regional metastases to nodal sites seen in up to 30% of cases in both genders, while distant metastases at presentation are rare (0-6%), but occur in up to 40% of cases with recurrent disease. Among men, the two most important prognostic factors are disease location and stage. Low-stage tumours (T1-2) and tumours involving the fossa navicularis or the penile urethra have a better prognosis than higher stage tumours (>T2 or N+) and lesions involving the bulbomembranous urethra. In women, in addition to stage and location, the size of the tumour has also prognostic implications. While surgery and radiation therapy (RT) are of benefit in early stage disease, advanced stage PUC requires multimodal treatment strategies to optimise local control and survival. These include induction chemotherapy followed by surgery or RT and concurrent chemoradiation with or without surgery. The latter strategy has been used successfully to treat other human papillomavirus-related cancers of the vagina, cervix and anus and may be of value in achieving organ preservation. Given the rarity of PUC, prospective multi-institutional studies are needed to better define the optimal treatment approach for this disease entity.

Abstract
CONTEXT The European Association of Urology (EAU) Guidelines Group on Muscle-Invasive and Metastatic Bladder Cancer prepared these guidelines to deliver current evidence-based information on the diagnosis and treatment of patients with primary urethral carcinoma (UC). OBJECTIVE To review the current literature on the diagnosis and treatment of patients with primary UC and assess its level of scientific evidence. EVIDENCE ACQUISITION A systematic literature search was performed to identify studies reporting urethral malignancies. Medline was searched using the controlled vocabulary of the Medical Subject Headings database, along with a free-text protocol. EVIDENCE SYNTHESIS Primary UC is considered a rare cancer, accounting for <1% of all malignancies. Risk factors for survival include age, tumour stage and grade, nodal stage, presence of distant metastasis, histologic type, tumour size, tumour location, and modality of treatment. Pelvic magnetic resonance imaging is the preferred method to assess the local extent of urethral tumour; computed tomography of the thorax and abdomen should be used to assess distant metastasis. In localised anterior UC, urethra-sparing surgery is an alternative to primary urethrectomy in both sexes, provided negative surgical margins can be achieved. Patients with locally advanced UC should be discussed by a multidisciplinary team of urologists, radiation oncologists, and oncologists. Patients with noninvasive UC or carcinoma in situ of the prostatic urethra and prostatic ducts can be treated with a urethra-sparing approach with transurethral resection and bacillus Calmette-Guérin (BCG). Cystoprostatectomy with extended pelvic lymphadenectomy should be reserved for patients not responding to BCG or as a primary treatment option in patients with extensive ductal or stromal involvement. CONCLUSIONS The 2013 guidelines document on primary UC is the first publication on this topic by the EAU. It aims to increase awareness in the urologic community and provide scientific transparency to improve outcomes of this rare urogenital malignancy.
