RESUMO

BACKGROUND: We examined the effect of disease-free interval (DFI) duration on cancer-specific mortality (CSM)-free survival, otherwise known as the effect of conditional survival, in radical urethrectomy nonmetastatic primary urethral carcinoma (PUC) patients. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) database 2000-2020, patient (age, sex, race/ethnicity, and marital status) and tumor (stage and histology) characteristics, as well as systemic therapy exposure status of nonmetastatic PUC patients were tabulated. Conditional survival estimates at 5-year were assessed based on DFI duration and according to stage at presentation (T1 -2N0 vs. T3-4N0-2). RESULTS: Of all 512 radical urethrectomy PUC patients, 278 (54%) harbored T1-2N0 stage versus 234 (46%) harbored T3-4N0-2 stage. In 512 PUC patients, 5-year CSM-free survival at initial diagnosis was 61.8%. Provided a DFI duration of 36 months, 5-year CSM-free survival was 85.6%. In 278 T1-2N0 PUC patients, 5-year CSM-free survival at initial diagnosis was 68.4%. Provided a DFI duration of 36 months, 5-year CSM-free survival was 86.9%. In 234 T3-4N0-2 PUC patients, 5-year CSM-free survival at initial diagnosis was 53.8%. Provided a DFI duration of 36 months, 5-year CSM-free survival was 83.6%. CONCLUSIONS: Although intuitively, clinicians and patients are well aware of the concept that increasing DFI duration improves survival probability, only a few clinicians can accurately estimate the magnitude of survival improvement, as was done within the current study. Such information is crucial to survivors, especially in those diagnosed with rare malignancies, where the survival estimation according to DFI duration is even more challenging.

RESUMO

Primary urethral carcinoma is a rare oncologic condition with limited data to support organ-sparing therapies. Herein, we present a case of primary urethral squamous cell carcinoma in situ of the bulbar urethra treated with intraurethral 5-fluorouracil (5-FU) who exhibited a complete pathologic response observed at the time of dismembered urethroplasty. The clinical features, diagnosis, and treatment course of our case are reviewed. These data may support the use of intraurethral 5-FU for similar cases in the future.

RESUMO

INTRODUCTION: Primary urethral carcinoma is a rare clinical entity with an incidence of 1 case per million in the United Kingdom. Cancers of the distal urethra are most commonly of squamous subtype and often associated with Human Papilloma Virus infection. Penile preserving techniques are recommended in tumours of the pendulous urethra with a number of surgical approaches described. Herein, we describe the surgical management of 7 patients presenting with primary urethral carcinoma. METHODS: Seven patients diagnosed with primary urethral carcinoma of the distal urethra were identified using a prospectively maintained penile cancer database at our institution from May 2017 to November 2020. RESULTS: The mean age at presentation was 56.5 (33-80) years. Presenting symptoms included visible lesion, LUTS and a groin mass. Three patients had lesions located within the glanular urethra and had a distal urethrectomy and primary closure. Two patients with lesions extending proximal to the glanular urethra and into or beyond the fossa navicularis had a distal urethrectomy with a hypospadic neomeatus formation. One patient with tumour extending into the glans penis underwent distal urethrectomy and partial glansectomy with split thickness skin graft. A partial penectomy was performed for one patient with urethral tumour invading the corporal heads. Mean follow-up was 23.4 (±17.0) months. There have been no disease recurrences to date. CONCLUSION: Penile preserving techniques are feasible in patients with tumours of the pendulous urethra and do not appear to compromise local control.

RESUMO

BACKGROUND: Primary urethral carcinoma (PUC) is a rare genitourinary malignancy with a relatively poor prognosis. The aim of this study was to examine the impact of surgery on survival of patients diagnosed with PUC. METHODS: A total of 1544 PUC patients diagnosed between 2004 and 2016 were identified based on the SEER database. The Kaplan-Meier estimate and the Fine and Gray competing risks analysis were performed to assess overall survival (OS) and cancer-specific mortality (CSM). The multivariate Cox regression model and competing risks regression model were used to identify independent risk factors of OS and cancer-specific survival (CSS). RESULTS: The 5-yr OS was significantly better in patients who received either local therapy (39.8%) or radical surgery (44.7%) compared to patients receiving no surgery of the primary site (21.5%) (p < 0.001). Both local therapy and radical surgery were each independently associated with decreased CSM, with predicted 5-yr cumulative incidence of 45.4 and 43.3%, respectively, compared to 64.7% for patients receiving no surgery of the primary site (p < 0.001). Multivariate analyses demonstrated that primary site surgery was independently associated with better OS (local therapy, p = 0.037; radical surgery, p < 0.001) and decreased CSM (p = 0.003). Similar results were noted regardless of age, sex, T stage, N stage, and AJCC prognostic groups based on subgroup analysis. However, patients with M1 disease who underwent primary site surgery did not exhibit any survival benefit. CONCLUSION: Surgery for the primary tumor conferred a survival advantage in non-metastatic PUC patients.

RESUMO

The International Collaboration on Cancer Reporting (ICCR) is a not-for-profit organisation sponsored by the Royal Colleges of Pathologists of Australasia and the United Kingdom, the College of American Pathologists, the Canadian Association of Pathologists in association with the Canadian Partnership Against Cancer, the European Society of Pathology, the American Society of Clinical Pathology and the Faculty of Pathology, Royal College of Physicians of Ireland. Its goal is to produce standardised, internationally agreed-upon, evidence-based datasets for cancer pathology reporting throughout the world. This paper describes the development of a cancer dataset by the multidisciplinary ICCR expert panel for the reporting of carcinoma of the urethra in urethrectomy specimens. The dataset is composed of 'required' (mandatory) and 'recommended' (non-mandatory) elements, which are based on a review of the most recent evidence and supported by explanatory commentary. Fourteen required elements and eight recommended elements were agreed by the international dataset authoring committee to represent the essential/required (core) and recommended (non-core) information for the reporting of carcinoma of the urethra in urethrectomy specimens. Use of an internationally agreed, structured pathology dataset for reporting carcinoma of the urethra (in urethrectomy specimens) will provide the necessary information for optimal patient management, will facilitate consistent data collection and will provide valuable data for research and international benchmarking. The dataset will be valuable for those countries and institutions that are not in a position to develop their own datasets.

RESUMO

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.

RESUMO

INTRODUCTION AND HYPOTHESIS: Accurate diagnosis of a wide spectrum of urethral/periurethral pathologies in women remains challenging due to its anatomical location and nonspecific clinical presentations. Magnetic resonance imaging (MRI) has emerged as the modality of choice for diagnosing female urethral and periurethral pathologies due to its multiplanar scanning capability, superior soft tissue differentiation, noninvasive nature, and overall excellent contrast resolution. METHODS: In this narrative review, we describe the use of MRI to visualize the female urethra and periurethral pathologies. RESULTS: MRI can confidently characterize lesions into cystic or solid, provide a more succinct differential diagnosis, and in some cases provide a specific and accurate diagnosis, enabling surgeons to prepare a roadmap before operative procedure. Moreover, functional MRI can be useful to assess dynamic disorders such as urethral hypermobility. CONCLUSIONS: We provide a comprehensive review of normal MR anatomy of the female urethra, as well as the MR features of practically important urethral and periurethral lesions.

RESUMO

BACKGROUND: To investigate the impact of perioperative chemo(radio)therapy in advanced primary urethral carcinoma (PUC). PATIENTS AND METHODS: A series of 124 patients (86 men, 38 women) were diagnosed with and underwent surgery for PUC in 10 referral centers between 1993 and 2012. Kaplan-Meier analysis with log-rank testing was used to investigate the impact of perioperative chemo(radio)therapy on overall survival (OS). The median follow-up was 21 months (mean: 32 months; interquartile range: 5-48). RESULTS: Neoadjuvant chemotherapy (NAC), neoadjuvant chemoradiotherapy (N-CRT) plus adjuvant chemotherapy (ACH), and ACH was delivered in 12 (31%), 6 (15%) and 21 (54%) of these patients, respectively. Receipt of NAC/N-CRT was associated with clinically node-positive disease (cN+; P = 0.033) and lower utilization of cystectomy at surgery (P = 0.015). The objective response rate to NAC and N-CRT was 25% and 33%, respectively. The 3-year OS for patients with objective response to neoadjuvant treatment (complete/partial response) was 100% and 58.3% for those with stable or progressive disease (P = 0.30). Of the 26 patients staged ≥cT3 and/or cN+ disease, 16 (62%) received perioperative chemo(radio)therapy and 10 upfront surgery without perioperative chemotherapy (38%). The 3-year OS for this locally advanced subset of patients (≥cT3 and/or cN+) who received NAC (N = 5), N-CRT (N = 3), surgery-only (N = 10) and surgery plus ACH (N = 8) was 100%, 100%, 50% and 20%, respectively (P = 0.016). Among these 26 patients, receipt of neoadjuvant treatment was significantly associated with improved 3-year relapse-free survival (RFS) (P = 0.022) and OS (P = 0.022). Proximal tumor location correlated with inferior 3-year RFS and OS (P = 0.056/0.005). CONCLUSION: In this series, patients who received NAC/N-CRT for cT3 and/or cN+ PUC appeared to demonstrate improved survival compared with those who underwent upfront surgery with or without ACH.

RESUMO

A 65-year-old man with stricture urethra underwent drainage of periurethral abscess and suprapubic cystostomy (SPC) placement. He presented to us 3 months later with a fungating ulcer at the site of perineal incision, the biopsy of which revealed squamous cell carcinoma (SCC). He underwent a total penile amputation, wide local excision scrotum, radical urethrocystoprostatectomy, ileal conduit with the en-bloc excision of the SPC tract. Histopathological examination of the suprapubic tract also revealed SCC. This is the first documented case of SCC of a suprapubic tract in the presence of primary urethral SCC.

RESUMO

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 defining 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.

RESUMO

Primary urethral carcinoma (PUC) is defined as a tumor process arising within the urethra, with no history of other urinary tract localization or synchronous tumor of the urinary tract. The most common histological types are urothelial carcinoma (UC), squamous cell carcinoma (SCC) and adenocarcinoma (AC). In men, UC predominates, while AC is rare. In women, AC affects around one in two patients, while EC and UC are equally divided between the remaining cases. Diagnosis is often delayed, and requires endoscopic examination with biopsies. MRI is the gold standard for local staging. FDG-PET scan can help in cases of doubt about regional or distant extension. The prognosis remains unfavorable despite aggressive surgical treatment. Multimodal management combining surgery, radiotherapy and chemotherapy appears to improve prognosis in severe forms.

RESUMO

INTRODUCTION AND IMPORTANCE: Primary urethral carcinoma (PUC) is exceedingly uncommon and accounts for 0.02 % of all female cancers and <1 % of female genitourinary tract malignancy. PUC in female usually presents late with a higher disease stage and, hence, has higher cancer-specific mortality. Due to its rarity, the current recommendation for the management of PUC is still unclear. CASE PRESENTATION: This study reports two rare cases of 59-year-old and 65-year-old women with PUC, presenting with chief complaint of hematuria. Urethrocystoscopy and biopsy were performed. Pathology results revealed mucinous adenocarcinoma (AC) and urothelial carcinoma (UC) of the urethra, respectively. Radiological imaging was conducted for staging. Both were diagnosed with cT4N2M0. The first patient underwent anterior pelvic exenteration with bilateral ureterocutaneoustomy (UCS), while the second patient received cisplatin-based chemotherapy before the surgery. Radiological follow-up was planned 3 months after the surgery. CLINICAL DISCUSSION: Both mucinous AC and UC are considered incredibly unusual subtypes, with no defined treatment guidelines. Anterior exenteration with or without neoadjuvant chemotherapy may be opted for advanced PUC affecting the proximal urethra and adjacent organs. Following the previous studies, in this case series, both patients (locally advanced) underwent anterior exenteration. Additionally, the UC subtype received multimodal treatment with neoadjuvant chemotherapy which was shown to improve overall survival. CONCLUSION: In conclusion, PUC is extremely rare, and the choice of management remained various. Long-term follow-up for these patients is mandatory to improve understanding of this incredibly uncommon disease.

RESUMO

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.

RESUMO

BACKGROUND: Unmarried status has been associated with advanced stage at presentation and lower treatment dose intensification rates in several urological and non-urological malignancies. However, no previous investigators focused of the association of unmarried status with locally advanced stage (T3-4N0-2) at presentation and lower bi-/trimodal therapy rates in primary urethral carcinoma (PUC) patients. To address these knowledge gaps, we relied on the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: Within the SEER database 2000 to 2020, all non-metastatic PUC patients were identified. Logistic regression models (LRMs) tested for differences in stage at presentation and treatment modality in the overall cohort and then in a sex-specific fashion, according to marital status (married vs unmarried). RESULTS: Of all 1,430 non-metastatic PUC patients, 1,004 (70%) were male vs 426 (30%) were female. Of 1,004 male PUC patients, 272 (27%) were unmarried. Of all 426 female PUC patients, 239 (56%) were unmarried. In multivariable LRMs predicting T3-4N0-2, unmarried status was independently associated with an increased risk of locally advanced stage at presentation in the overall cohort (odds ratio [OR]:1.31; P = 0.03) and in female patients (OR:1.62; P = 0.02), but not in male PUC patients (P = 0.6). In multivariable LRMs predicting bi-/trimodal therapy, unmarried status was an independent predictor of lower bi-/trimodal therapy rates in the overall cohort (OR:0.73; P = 0.02) and in male patients (OR:0.60; P = 0.007), but not in female PUC patients (P = 0.6). CONCLUSIONS: Unmarried female PUC patients more likely harbored locally advanced stage at presentation. Conversely, unmarried male PUC patients are less likely to benefit from bi-/trimodal therapy.

RESUMO

Primary urethral carcinoma (PUC) is a rare disease with frequent nodal metastasis at the time of diagnosis. Few risk factors have been established and overall prognosis remains poor. As of now, no clear therapeutic guidelines are established and management of advanced PUC often involves surgery which can have negative functional and psychological outcomes for the patient. Few authors have already reported the use of chemoradiotherapy alone to avoid surgery with some good short-term results. We report the case of a 48-year-old woman with advanced high-grade urothelial carcinoma of distal urethra associated to bilateral inguinal nodal metastasis. She was similarly and successfully treated using chemoradiotherapy exclusively without significant adverse effects. This experience reinforces benefits of a surgery-sparing management, when possible, as recommended in current guidelines.

RESUMO

INTRODUCTION: Primary urethral carcinoma is a rare disease with overall poorer outcomes in the past. It is relatively more uncommon in female sex. CLINICAL PRESENTATION: We present a case of a female with primary urethral carcinoma that presented atypically as a vulval mass without any features of storage, voiding lower urinary tract symptoms, or gross haematuria. DISCUSSION: As primary urethral carcinoma is rare in occurrence, prospective studies are limited so as the recommendations to guide treatment options. Treatment recommendations are still on development from different small-scale studies as well as from data in higher volume centers. Management options depends on location, extent, histology of the lesion as well as on sex of the patient and fitness of the patient. CONCLUSION: Early diagnosis and treatment with multidisciplinary consult and multimodality will improve the overall survival rate and quality of life of the patients.

RESUMO

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.

RESUMO

Primary urethral carcinoma (PUC) has a low incidence, but with high aggressiveness. Most of the patients are found in late stage, with poor prognosis. At present, chemotherapy is still the main treatment for metastatic PUC, but it has limited effect. Here, we report a case of metastatic PUC with low HER2 expression that developed disease progression after multiline therapy including chemotherapy, programmed death-1 (PD-1) inhibitors and multi-targeted receptor tyrosine kinase (RTK) inhibitor. After receiving Disitamab Vedotin(a novel antibody drug conjugate, ADC) and toripalimab (a PD-1 inhibitor), the patient achieved persistent PR, and the PFS exceeded 12 months up to now. Our report indicates that, despite the patient of metastatic PUC has low expression of HER2, it is still possible to benefit from Disitamab Vedotin combined with PD-1 inhibitor, which may reverse the drug resistance of PD-1 inhibitor and chemotherapy to a certain extent. But larger sample studies are needed to determine the efficacy of this treatment strategy and its impact on survival.

RESUMO

Introduction: and importance: Urethral cancer is a rare condition. It represents less than 1% of all cancers and the clinical signs are not very specific and confusing, which explains the often-late diagnosis. The prognosis can be poor. The objective of our observation is to discuss, through a review of the literature, the diagnostic and therapeutic means of tumors of the male anterior urethra. Case presentation: This is a 54-year-old patient, smoker, followed for urinary lithiasis. He initially consulted us for right nephritic colic, with an obstructive iliac ureteral stone on a CT scan. He had drainage by JJ stent followed by extracorporeal lithotripsy. After three months, it was decided to remove the JJ Stent. During urethrocystoscopy, a papillary tumor of the anterior urethra was found, measuring 0.5 cm on the long axis. Endoscopic resection of the tumor was performed. Pathological examination revealed a low-grade malignant urothelial carcinoma. No tumor recurrence was noted after one year of follow-up. Discussion: Primary urethral cancer is a rare condition. Most series in the literature show a male predominance. The main risk factors are chronic inflammation, history of urethritis, and urethral stricture. The clinical signs of urethral cancer are usually discrete and not very specific. The reference examination for positive diagnosis remains urethroscopy, which allows a more precise diagnosis thanks to a direct view of the urethral mucosa. The management of tumors of the anterior urethra consisted of aggressive excisional surgery. The main goal was to achieve satisfactory local control. conservative treatment by resection, fulguration or laser vaporization is indicated for small lesions (<1 cm). Conclusion: Tumors of the anterior urethra in men are often diagnosed late. More effort should be made to diagnose this disease earlier, especially in high-risk groups. Conservative treatment can be offered in patients with a small lesion.
