Abstract
INTRODUCTION This study is to examine the predictors of survival and to construct a nomogram for predicting the overall survival (OS) of primary bladder signet ring cell carcinoma (SRCC) patients based on the analysis of the Surveillance, Epidemiology, and End Results (SEER) database. METHODS A total of 219 eligible patients diagnosed with SRCC were analyzed using the 2004-2015 data from SEER database. Univariate and multivariate Cox regression were used to determine independent prognostic factors, followed by development of a nomogram based on the multivariate Cox regression models. The consistency index (C-index), receiver operating characteristic (ROC) curve, and calibration curve were used to validate the prognostic nomogram. RESULTS The nomograms indicated appreciable accuracy in predicting the OS, with C-index of 0.771 and 0.715, respectively. The area under the curve (AUC) of the nomogram was 0.713 for 1 year, 0.742 for 3 years, and 0.776 for 5 years in the training set, while was 0.730 for 1 year, 0.727 for 3 years, and 0.697 for 5 years in the validation set. The calibration curves revealed satisfactory consistency between the prediction of deviation correction and ideal reference line. CONCLUSIONS The prognostic nomogram developed in the analytical data of SEER it provided high accuracy and reliability in predicting the survival outcomes of primary bladder SRCC patients and could be used to comprehensively assess the risk of SRCC. Moreover, they could enable clinicians to make more precise treatment decisions for primary bladder SRCC patients.

Abstract
Introduction The aim of this study is to examine the treatment pattern and predictors of long-term survival of patients with primary signet ring cell carcinoma (PSRCC) of the urinary bladder based on the analysis of the SEER database. Methods The 3-year and 5-year overall survival (OS) and cancer-specific survival (CSS) were calculated using the Kaplan–Meier method. Then, we compared the CSS curves by the log-rank test. The independent risk factors were determined using univariate and multivariate Cox regression. Results The 3-year OS and CSS rates for PSRCC of the bladder were 25.3% and 33.3%. The 5-year OS and CSS rates for the entire cohort were 16.4% and 25.2%. The CSS rates, respectively, were 0, 25.0, 66.7, 33.2, 42.4, and 31.7% at 3 years and 0, 25.0, 34.3, 24.1, 27.2, and 31.7% at 5 years for none, transurethral resection of the bladder (TURB), partial cystectomy, radical cystectomy with reconstruction, pelvic exenteration, and other surgeries (P = 0.001). Multivariate analyses showed independent risk factors only including T stage, M stage, lymph node removal, and surgical approach. Conclusions T stage, M stage, lymph node removal, and surgical approach are independent risk factors of PSRCC of the urinary bladder. TURB and radical cystectomy with reconstruction appear to provide a better outcome.

Abstract
Background Signet ring cell carcinoma (SRCC) is a rare but highly malignant variant of bladder carcinoma. Nomograms have demonstrated good accuracy in predicting the prognosis and guiding the management of pure urothelial carcinoma (UC). However, no accurate and applicable nomogram has been formulated for primary SRCC cases. This study aimed to determine significant prognostic factors and to construct nomograms for predicting the survival outcomes of patients with primary SRCCs of the urinary bladder. Methods A total of 317 eligible patients diagnosed with SRCC were analyzed using the 2004–2016 data from the Surveillance, Epidemiology, and End Results database. Univariate and multivariate analyses were performed to explore the prognostic values. Nomograms were established to estimate the overall survival (OS) and cancer-specific survival (CSS) based on the Cox regression results. The performance of SRCC nomograms was evaluated using the concordance index and calibration curves. Survival curves were applied according to various surgical methods, lymph node status, and risk groups distinguished by nomograms. Results Two nomograms included common indicators that were significantly associated with OS and CSS, including T stage, M stage, tumor size, surgery, and the lymph node ratio (LNR). The nomograms indicated appreciable accuracy in predicting the OS and CSS, with concordance index of 0.723 [95% confidence interval (95% CI: 0.692–0.754] and 0.740 (95% CI: 0.701–0.779), respectively. The calibration curves revealed satisfactory consistency between the prediction of deviation correction and ideal reference line. Conclusions The two nomograms developed in this study showed high accuracy and reliability in predicting the survival outcomes of patients with SRCC and could be used to comprehensively assess the risk of SRCC. Moreover, they could assist in the optimal treatment selection for such patients.

Abstract
Primary signet-ring cell carcinoma of the urinary bladder is a rare tumor. The overall incidence is approximately 0.12-0.6% of all urinary bladder malignancies. The majority of the patients present in an advanced stage with a uniformly grim prognosis. As signet-ring cell carcinomas are more common in the gastrointestinal tract, a possibility of metastasis needs to be considered. Here we report, a 42-year-old patient who presented with hematuria and was diagnosed with a urinary bladder tumor. The patient was managed with partial cystectomy and pelvic lymph node dissection. The histopathological examination confirmed primary signet-ring cell carcinoma of the urinary bladder.

[PMID: 32462187 PMCID: PMC7850530 DOI: 10.1093/jnci/djaa078] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 05/04/2020] [Accepted: 05/21/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Immunosuppressed solid organ transplant recipients (SOTRs) have elevated rates of certain rare cancers caused by viruses. Evaluating risk of rare cancers among SOTRs may provide etiological clues for additional cancers linked to poor immunity and viral infections. METHODS We performed a cohort study of 262 455 SOTRs (1987-2014) from the US SOTR registry linked to 17 population-based cancer registries. First cancers in SOTRs were categorized using an established classification scheme based on site and histology. Standardized incidence ratios (SIRs) compared risk in SOTRs with the general population. We used Poisson regression to calculate incidence rate ratios according to immune-related SOTR characteristics, including time since transplant (ie, duration of immunosuppression). All statistical tests were 2-sided. RESULTS We examined 694 distinct cancer subtypes, with 33 manifesting statistically significantly elevated SIRs (Bonferroni P < 7.2 × 10-5). All 33 are rare (incidence <6 per 100 000 person-years) and several have known viral etiology (eg, Merkel cell carcinoma: SIR = 24.7, 95% confidence interval [CI] = 20.8 to 29.1). Additional cancers that were increased include squamous cell carcinomas of the lip (SIR range = 18.3-19.8), eye and adnexa (SIR = 13.8, 95% CI = 7.9 to 22.3), salivary gland (SIR = 9.3, 95% CI = 6.1 to 13.5), and nasal cavity and sinuses (SIR = 4.5, 95% CI = 2.8 to 6.8); sebaceous adenocarcinoma (SIR = 34.3, 95% CI = 26.3 to 44.0); malignant fibrous histiocytoma (15.4); and subtypes of bladder, kidney, lung, and colon cancer (SIR range = 3.2-13.3). Incidence of several cancers increased over time since transplant (Ptrend < .05), including squamous cell carcinomas of the lip, salivary gland, and anogenital sites. CONCLUSIONS SOTRs experience elevated rates of several rare cancers. Because some of these cancers exhibit aggressive behavior with poor outcomes, it is important to further characterize the role of immunity and the potential involvement of oncogenic viruses to improve prevention and treatment.

Abstract
Background: Primary signet-ring cell carcinoma (SRCC) is a rare variation of adenocarcinoma. Although SRCC of the urinary bladder is highly malignant, it is often neglected due to its rarity. Materials and Methods: We used the national Surveillance, Epidemiology, and End Results (SEER) database (2004–2016) to compare SRCC with urothelial carcinoma (UC) and investigated the prognostic values of the clinicopathological characteristics and survival outcomes in SRCC of the urinary bladder. Multivariable Cox proportional hazard model, subgroup analyses, and propensity score matching (PSM) were used. Results: In all, 318 patients with SRCC and 57,444 patients with UC were enrolled. Compared with those with UC, patients with SRCC were younger at diagnosis (P < 0.001) and had higher rates of muscle invasive disease (P < 0.001), lymph node metastasis (P < 0.001), and distal metastasis (P < 0.001), as well as higher-grade tumors (P = 0.004). A Cox proportional hazard regression analysis showed that the SRCC group was associated with significantly higher risks of overall mortality (OM) compared with the UC group [hazard ratios (HR) = 1.44, 95% confidence intervals (95% CI) = 1.26–1.63, P < 0.0001]. Patients with SRCC also had a higher risk of cancer-specific mortality (CSM; HR = 1.40, 95% CI = 1.18–1.65, P < 0.0001). After PSM, the SRCC group also experienced higher risks of OM (HR = 1.45, 95% CI = 1.24–1.68, P < 0.0001) and CSM (HR = 1.47, 95% CI = 1.20–1.79, P = 0.0001) compared with the UC group. In the subgroup analyses, no significant interactions were observed in sex, age, N stage, M stage, and lymph nodes removed in terms of both OM and CSM. Conclusion: The prognosis of SRCC is poorer than that of UC, even after adjustment for baseline demographic and clinicopathological characteristic as well as cancer treatment. SRCC is an independent prognostic factor for patients with urinary bladder cancer.

Abstract
OBJECTIVE The aim of the present study was to emphasize the critical importance of the clinician's awareness of signet-ring cell carcinoma (SRCC) of the urinary bladder, a rare and aggressive disease entity. MATERIALS AND METHODS A review of the current literature was conducted and a classic case of advanced SRCC of the urinary bladder is reported, clearly demonstrating the severity of this disease and the imperative need for standardized recommendations for the diagnostic work-up and management of urinary bladder SRCC. RESULTS The prognosis for patients with SRCC of the urinary bladder is poor, attributed to presentation at advanced stages following asymptomatic progression, inefficacy of multimodality therapy and possibly an aggressive underlying biological phenotype. Treatment options are limited and not well studied. CONCLUSION Given the rarity of SRCC, multi-institutional clinical trials and international cooperation are mandatory to improve survival for patients with primary SRCC of the bladder.

Abstract
OBJECTIVES To examine contemporary rates of pathological features and mortality for adenocarcinoma of the urinary bladder in the USA using population-based data analysis. METHODS We relied on 10 024 patients with non-metastatic bladder cancer diagnosed between 2004 and 2013 within the Surveillance, Epidemiology and End Results registries. Logistic regression analyses focused on grade and stage. Kaplan-Meier analyses assessed cancer-specific mortality rates in adenocarcinoma and urothelial carcinoma of the bladder. Cox regression analyses assessed the impact of histological subtype on cancer-specific mortality. RESULTS Overall, 215 (2.1%) adenocarcinoma and 9809 (97.9%) urothelial carcinoma patients were identified. The rate of non-organ-confined disease was higher in adenocarcinoma (64.7% vs 50.8%, P < 0.001). In multivariable logistic regression analyses, adenocarcinoma patients had a 2.2-fold higher risk of harboring non-organ-confined disease (95% confidence interval 1.7-3.0; P < 0.001) than urothelial carcinoma patients. Cancer-specific mortality-free survival rates were lower in adenocarcinoma (P < 0.01). This disadvantage only applied to non-organ-confined disease (P = 0.044), and not to organ-confined disease (P = 0.9). In multivariable Cox regression analyses, adenocarcinoma conferred a 1.3-fold higher rate of cancer-specific mortality (hazard ratio 1.30, 95% confidence interval 1.05-1.60; P = 0.01). Among adenocarcinoma patients, 30.7% harbored signet-ring cell adenocarcinoma and portended particularly poor cancer-specific mortality rates. CONCLUSIONS In bladder cancer, adenocarcinoma presents at higher stages than urothelial carcinoma. However, cancer-specific mortality rates do not differ. A more unfavorable stage at diagnosis and higher cancer-specific mortality apply to the signet-ring cell variant.
