Abstract
INTRODUCTION Urachal carcinoma (UrC) is a rare, nonurothelial malignancy, comprising less than 1% of all bladder cancers. It usually affects males in their fifth to sixth decade and is often diagnosed at an advanced stage with metastasis. This study examines UrC population characteristics and management. METHODS We identified UrC patients from bladder biopsies or TURB in the PearlDiver Mariner database (2010-2022). Descriptive statistics detailed patient characteristics. Student's T-Tests compared ages for partial vs. radical cystectomy, and Fisher's exact test compared SDOH presence. Significance was set at P < .05. Analyses used R version 3.6.0 within PearlDiver's software. RESULTS Among 2475 UrC patients (mean age 69.2 ± 9.2 years, 73.1% men), most were in the south (36.5%), outpatient settings (84.5%), and privately insured (65.3%). A total of 418 (16.2%) had at least 1 SDOH. Imaging before diagnosis was used in 65.74% of patients, primarily ultrasound. Smoking was present in 54.5%, diabetes in 42.9%, and obesity in 25.2%. After diagnosis, 1246 (50.34%) had localized disease; 407 underwent radical cystectomy and 330 partial cystectomy. Patients undergoing radical cystectomy were older (66.74 ± 8.13 years) compared to those undergoing partial cystectomy (60.55 ± 12.92 years) (P < .001), with SDOH factors more prevalent in the partial cystectomy group (P = .03). CONCLUSION UrC is a rare, often advanced-stage cancer predominantly affecting older men. Our study shows a trend towards partial cystectomy for localized UrC. Further research is needed to personalize surgery and integrate multidisciplinary approaches for better outcomes.

Abstract
INTRODUCTION Urachal carcinoma is characterized by high malignancy, poor prognosis, and late stage of diagnosis. There is a lack of unanimous clinical treatment guidelines. We summarize the characteristics, treatment, and outcomes of urachal carcinoma from our center, hoping to provide a reference for diagnosis and treatment. METHODS We retrospectively analyzed the clinical data of 21 patients with urachal carcinoma who were treated at our center from January 2010 to August 2022, and all patients were followed up. RESULTS The average survival time was 67.1 ± 9.1 (ranging from 49.3 to 84.9) months. The average relapse-free survival was 48.8 ± 9.9 (ranging from 29.5 to 68.2) months. Six patients received adjuvant therapy, mainly chemotherapy. Five patients died during follow-up. CONCLUSIONS Early physical examination may be helpful for early detection of urachal carcinoma. Surgical treatment is still preferred for localized urachal carcinoma. Lymph node dissection may facilitate accurate staging, and positive margin usually results in a worse prognosis. Adjuvant therapy, mainly chemotherapy, may help improve the prognosis. The application of radiotherapy, targeted therapy, and immunotherapy still needs further exploration.

Abstract
Objectives We sought to evaluate modern diagnostic and treatment options for urachal adenocarcinoma (UAC) and to provide clarity regarding the available options and their outcomes for this poorly understood yet damaging disease. Material and methods We conducted a systematic literature search in PubMed and Medline focusing on updated management of UAC. Results Surgical intervention continues to be the mainstay of treatment for localized UAC. However, with the increased availability of molecular and genetic profiling, chemotherapy has consistently demonstrated promising response rates and survival outcomes, especially for a disease that commonly presents in a metastatic stage. The role of checkpoint inhibitors remains under investigation. Cross-sectional imaging is vital during postoperative surveillance. However, there may also be a role for the adoption of cystoscopy to detect bladder recurrence. Conclusions Although the importance of surgical resection remains unchanged, improved survival outcomes with chemotherapy have been found in small retrospective studies. Randomized trial data are required to further assess the influence of systemic treatment as a primary or adjuvant therapy. Moreover, a stringent follow-up regimen incorporating evaluation for distant and local recurrence of UAC must be evaluated and adopted.

Abstract
Urachal cancer is a rare genitourinary malignancy that arises from the embryologic remnant of the urachus. The malignancy is considered to be aggressive, with no clear consensus on appropriate management for advanced disease. Although traditionally considered to be related to bladder cancer given its embryologic origin, several next generation sequencing studies have revealed the genomic profile of this genitourinary malignancy most closely resembles colorectal cancer. Moreover, these studies have identified potentially actionable mutations including EGFR, KRAS and MET. In addition, recent data suggests that immunotherapy may benefit some patients with advanced urachal cancer. Nonetheless, continued research is warranted to better understand how to treat this rare genitourinary cancer.

Urachal carcinoma: The journey so far and the road ahead. Pathol Res Pract 2023; 243:154379.

Abstract
Urachal carcinoma, a rare cancer arising from urachus, accounts for about 1% of bladder cancer. The diagnosis at stage I shows about 63% 5-year survival whereas only 8% of the patients at stage IV shows a 5-year survival. Above 90% of urachal carcinomas are adenocarcinomas and most of the urachal carcinoma cases are invasive, showing a high resemblance to adenocarcinoma of various origins, making it hard for a conclusive diagnosis. Even though inconclusive, immunohistochemistry can play a significant role in identifying urachal carcinoma. Most cases show the biomarkers CK20 and CDX2, whereas CK7 and β-catenin are expressed at a lesser frequency. Due to the few cases available, there is a lack of evidence regarding specific markers differentiating urachal carcinoma from colorectal or primary bladder adenocarcinomas. In addition to immunohistochemistry, genomic characterization is emerging to play a role in the classification and treatment of the disease. Urachal carcinoma has been reported to have a molecular level similarity with colorectal malignancies regarding certain gene expressions. The TP53 mutations inactivating the tumor suppressor can probably be explored as a possible target in treating urachal carcinoma. Additionally, certain targets identified in gastric and breast cancer along with anti-HER2 treatment strategies can be explored. Immuno-oncology utilizes immune checkpoint inhibitors for the treatment of MSI-H tumors whereas a combination of tyrosine kinase inhibitors along with immune checkpoint inhibitors are being studied to treat MSI stable tumors. The article is an in-depth overview of urachal carcinoma addressing the current landscape with an emphasis on the future scenario.

Abstract
BACKGROUND We relied on the most contemporary Surveillance, Epidemiology, and End Results (SEER) database and tested the hypothesis that chemotherapy may improve survival in metastatic urachal carcinoma (m-UraC). MATERIAL AND METHODS Within the SEER database (2004-2016), we identified m-UraC patients aged ≥ 18 years. Propensity score matching (PSM: cystectomy status, age and sex), Kaplan-Meier plots, cumulative incidence plots, Cox regression models and competing risks regression (CRR) models addressed overall mortality (OM) and cancer-specific mortality (CSM). RESULTS Overall, 274 m-UraC patients were identified with a median age of 70 years. Most were male (66%) and Caucasian (72%). Overall, 32% received chemotherapy. Chemotherapy-exposed patients were younger (62 vs. 73 years, p<0.001) and more frequently underwent cystectomy (19 vs. 8%, P = 0.014). In 274 m-UraC patients, median OM and CSM were 6 (4 -10) months and 8 (6 -14) months, respectively. After 1:1 PSM, chemotherapy-exposed patients exhibited lower OM (median 16 vs. 3 months; multivariable HR 0.38, P <0.001) and lower CSM (median 17 vs. 4 months; multivariable CRR HR 0.52, P = 0.001). The association between chemotherapy and better survival was even stronger in younger (≤70 years) patients (OM HR: 0.23, P <0.001; CSM CRR HR: 0.42, P = 0.001), but not in older (≥71 years) patients (OM HR: 0.61, P = 0.2; CSM CRR HR: 1.02, P = 1), after PSM and multivariable adjustments. CONCLUSION Overall, we validated the very aggressive nature of UraC, when distant metastases are present, and observed that m-UraC patients exposed to chemotherapy exhibited lower OM and CSM.

Abstract
Background Urachal cancer is a rare neoplasm in the urological system. To our knowledge, no published study has explored to establish a model for predicting the prognosis of urachal cancer. The present study aims to develop and validate nomograms for predicting the prognosis of urachal cancer based on clinicopathological parameters. Methods Based on the data from the Surveillance, Epidemiology, and End Results database, 445 patients diagnosed with urachal cancer between 1975 and 2018 were identified as training and internal validation cohort; 84 patients diagnosed as urachal cancer from 2001 to 2020 in two medical centers were collected as external validation cohort. Nomograms were developed using a multivariate Cox proportional hazards regression analysis in the training cohort, and their performance was evaluated in terms of its discriminative ability, calibration, and clinical usefulness by statistical analysis. Results Three nomograms based on tumor–node–metastasis (TNM), Sheldon and Mayo staging system were developed for predicting cancer-specific survival (CSS) of urachal cancer; these nomograms all showed similar calibration and discrimination ability. Further internal (c-index 0.78) and external (c-index 0.81) validation suggested that Sheldon model had superior discrimination and calibration ability in predicting CSS than the other two models. Moreover, we found that the Sheldon model was able to successfully classify patients into different risk of mortality both in internal and external validation cohorts. Decision curve analysis proved that the nomogram was clinically useful and applicable. Conclusions The nomogram model with Sheldon staging system was recommended for predicting the prognosis of urachal cancer. The proposed nomograms have promising clinical applicability to help clinicians on individualized patient counseling, decision-making, and clinical trial designing.

Abstract
PURPOSE OF REVIEW The aim of this review is to sum up the state of the art of urachal carcinoma (UC) in order to easily guide clinicians. RECENT FINDINGS UC is a rare and aggressive disease with consequent few data about diagnosis and treatment. Dates are mainly based on retrospective trial and case reports with limited prospective trial. Clinical presentation is not specific, often with urinary symptoms. Diagnosis is mainly based on CT scan and MRI, useful to evaluate local invasion and nodal status and to detect the presence of distant metastases. Therefore, biopsy is needed to obtain histological confirmation. Surgery is the gold standard for localized disease, while different chemotherapy schemes have been used in metastatic setting. Novel findings based on mutational analysis of the tumor include the use of biological treatment, such as cetuximab, and immunotherapy, such as atezolizumab, with satisfactory responses, suggesting that personalized treatment could be the most suitable option for UC.

Abstract
Urachal cancer is a rare but aggressive disease. In addition to the non-glandular tumors, non-cystic urachal adenocarcinomas are nowadays distinguished from the primary cystic variant. (Immunohistochemical) markers are only of minor differential diagnostic value and, therefore, the diagnosis is primarily established in a multidisciplinary approach. The non-cystic variant accounts for the majority of cases (83%), is more common in men (63%), shows a median age at diagnosis of 51 years and has a 5-year survival rate of about 50%. In organ-confined disease, usually a partial cystectomy of the tumor in the bladder dome, including the median umbilical ligament and umbilicus, is performed. In advanced stages, systemic therapy is needed while 5‑fuorouracil (5-FU) containing regimes have been shown to be more effective. Due to the rarity of the tumor, targeted therapy approaches based on a biological rationale are becoming increasingly relevant. As molecular data are still sparse, we compiled and analyzed the largest urachal cancer cohort to date. In 31% of the cases, MAPK-/PI3K signaling pathway alterations were detected (especially in K-/NRAS) with implications for anti-EGFR therapy approaches. Further potentially therapeutic alterations were detected in FGFR1, MET, PDGFRA, and erbB2/HER2. Additionally, PD-L1 tumor cell expression (clone: 22C3) was demonstrated in 16% of cases, therefore making anti-PD-1/PD-L1 immuno-oncological approaches worth considering despite the absence of mismatch repair deficiency (MMR-d) and/or high microsatellite instability (MSI-h). Finally, urachal adenocarcinomas seem to be a distinct entity on the molecular level with closer resemblance to colorectal adenocarcinomas than to urothelial carcinomas.

Abstract
Urachal cancer (UrC) is a rare but aggressive cancer. Due to overlapping histomorphology, discrimination of urachal from primary bladder adenocarcinomas (PBAC) and adenocarcinomas secondarily involving the bladder (particularly colorectal adenocarcinomas, CRC) can be challenging. Therefore, we aimed to give an overview of helpful (immunohistochemical) biomarkers and clinicopathological factors in addition to survival analyses and included institutional data from 12 urachal adenocarcinomas. A PubMed search yielded 319 suitable studies since 1930 in the English literature with 1984 cases of UrC including 1834 adenocarcinomas (92%) and 150 nonadenocarcinomas (8%). UrC was more common in men (63%), showed a median age at diagnosis of 50.8 years and a median tumor size of 6.0 cm. No associations were noted for overall survival and progression-free survival (PFS) and clinicopathological factors beside a favorable PFS in male patients (p = 0.047). The immunohistochemical markers found to be potentially helpful in the differential diagnostic situation are AMACR and CK34βE12 (UrC versus CRC and PBAC), CK7, β-Catenin and CD15 (UrC and PBAC versus CRC), and CEA and GATA3 (UrC and CRC versus PBAC). Serum markers like CEA, CA19-9 and CA125 might additionally be useful in the follow-up and monitoring of UrC.

Abstract
Urachal carcinoma is an uncommon cancer whose rarity has precluded its study and evidence-based management strategies are lacking. This study assessed all urachal carcinomas in Ireland and clinical parameters in order to improve understanding. Urachal carcinomas diagnosed from 1994 to 2011 were identified from the National Cancer Registry in Ireland. Data obtained included patient age, gender, diagnostic year, pathology, tumor stage, patient treatment strategies and survival. Twenty-six urachal carcinomas were identified, the majority being adenocarcinoma. This comprised 0.3% of all invasive bladder tumors. Patients were predominantly male (62%) and over 50 years of age (58%). Twenty-two patients (85%) underwent surgery, with only six (23%) undergoing chemotherapy. On average, median overall survival was 2.6 years (range 0-15.2 yrs). Survival was longer in women (5 vs. 1.9 yrs), patients under 50 years of age (3.6 vs. 1.9 yrs), those without confirmed metastasis (4.1 vs. 0.7 yrs) and those who received chemotherapy (3.6 vs. 2.6 yrs). The overall survival of urachal carcinoma in Ireland is less than expected from published literature. This study highlights the need for centralization of rare tumors with international collaboration to identify the optimal treatment strategy and improve outcome.

Abstract
BACKGROUND The urachus is a vestigial tubular structure that connects the urinary bladder to the allantois during early embryonic development. Urachal carcinoma develops in the urachus, which is an embryological remnant of the urogenital sinus and allantois. The estimated annual incidence of urachal carcinoma in the general population is 0.01% of all cancers in adults. Moreover, urachal carcinoma accounts for 0.34% to 0.7% of all bladder carcinoma cases. And breast metastasis is extremely rarer. METHODS AND RESULTS A 42-year-old woman was admitted to our hospital with a palpable mass in the outer upper quadrant of the right breast, which was misinterpreted as a carcinoma that originated from the breast. Subsequently, she underwent surgery without any further meticulous examination. Immunohistochemistry analysis revealed positivity for CK20, Villin, and CDX-2 and negativity for CK7. After further inspection, a mass was found in the bladder dome using 18F-fluorodeoxyglucose positron emission tomography and computed tomography. The mass was surgically removed. CONCLUSION Pathologic and immunohistochemical examination confirmed that the mass was urachal mucinous adenocarcinoma and mucinous adenocarcinoma to the right breast. The patient has been followed up without recurrence for 8 months.

Urachal Carcinoma of the Bladder: Impact of Clinical and Immunohistochemical Parameters on Prognosis. J Urol 2015; 195:1690-6. [PMID: 26678957 DOI: 10.1016/j.juro.2015.11.067] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/28/2015] [Indexed: 11/22/2022]
Abstract
PURPOSE Urachal carcinoma of the bladder is a rare malignancy. Its histological phenotype is similar to that of primary bladder and colorectal adenocarcinoma. The aim of this study was to explore the expression and prognostic relevance of 6 select protein markers of urachal carcinoma of the bladder, including p53, Ki67, RHAMM, BGN, IMP3 and MMP-7, which were formerly shown to be prognostic in urothelial carcinoma and colorectal adenocarcinoma. MATERIALS AND METHODS Clinical and followup data were obtained on a total of 26 patients with urachal carcinoma of the bladder treated at 2 university hospitals. Immunohistochemical analysis of p53, Ki67, RHAMM, BGN, IMP3 and MMP-7 expression was performed in samples from 15 patients. Clinicopathological parameters and immunohistochemical results were tested for prognostic value on univariable and multivariable analyses. RESULTS Followup was 50 months. Five-year overall and progression-free survival was 46% and 32%, respectively. On multivariable analysis a positive resection margin was an independent predictor of poor overall survival (p = 0.025). RHAMM (p = 0.0431), IMP3 (p = 0.0052), Ki67 (p = 0.0006) and p53 (p = 0.0024) expression rates were significantly increased in urachal carcinoma of the bladder cells compared to normal urothelium. IMP3 was elevated in Sheldon tumor stage IIIA compared to IIIB or greater (p = 0.0048). None of the analyzed protein markers was associated with survival. CONCLUSIONS The independent prognostic value of a positive resection margin underlines the importance of complete surgical removal of urachal carcinoma of the bladder combined with en bloc resection of the median umbilical ligament and umbilicus. Our results in a limited number of samples show that Ki67, p53, RHAMM and IMP3 expression is enhanced but has no prognostic significance in urachal carcinoma of the bladder.
