Leiomyosarcoma of urinary bladder (LMS-UB) is a highly malignant mesenchymal tumor, accounting for less than 0.5% of all bladder malignancies, with a predominant clinical presentation of hematuria. Here we report a case of low-grade LMS-UB. A 44-year-old male patient was admitted to the hospital with urodynia for 2 weeks. The patient's pelvis CT showed a mass on the right part of the bladder. For this reason, he was initially diagnosed with bladder cancer. We performed a robot-assisted laparoscopic enucleation of the bladder tumor and low-grade LMS-UB was diagnosed with the histopathological examination. He underwent 5 cycles of adjuvant chemotherapy after surgery. At 19months postoperative follow-up, the patient had no symptoms, recurrence, or distant metastasis. There is no report on the treatment of LMS-UB with minimally invasive enucleation worldwide. This case provides a new comprehensive treatment method of enucleation combined with adjuvant chemotherapy for early low-grade LMS-UB to reduce complications and improve patients' quality of life after surgery.

OBJECTIVE:
To investigate the correlation between expression levels of adipokine and clinicopathological features and prognosis of patients with upper tract urothelial carcinoma (UTUC) based on immunohistochemical staining and bioinformatics analysis.
METHODS:
The 8 adipokines in this study included adiponectin (AdipoQ), leptin (LEP), interleukin (IL)-6, IL-10 and their receptors (AdipoR1, AdipoR2, LEPR, IL-6R, IL-10RA, IL-10RB). Tissue samples of patients with UTUC who underwent surgical treatment in Peking University People's Hospital from January 2014 to April 2021 were selected for immunohistochemical staining. Their quantitative gene expression data were calculated by H-Score, and relevant clinical and follow-up data were collected retrospectively. Transcription group sequencing data of UTUC patients in Gene Expression Omnibus database (GSE134292 dataset) were downloaded for comparison. Chi-square test or t-test was used to compare the expression level of adipokine between non-muscle invasive group and muscle invasive group. Univariate and multivariate Cox regression analysis and Kaplan-Meier survival curve were utilized to analyze independent predictors of overall survival (OS), disease-free survival (DFS), intravesical recurrence-free survival (IVRFS) in the both cohorts. The P < 0.05 was considered statistically significant.
RESULTS:
In the study, 63 tissue samples of the patients with UTUC who underwent surgical treatment in Peking University People's Hospital and 57 UTUC patients in GSE134292 dataset were selected. In immunohistochemical cohort, the expressions of AdipoQ (P=0.003 6), AdipoR1 (P=0.006 5), LEP (P=0.007 7), IL-10 (P=0.006 9), and IL-10RA (P=0.008 9) were statistically higher in muscle invasive group. In GSE134292 cohort, the expressions of AdipoR1 (P=0.000 4), AdipoR2 (P=0.000 4), IL-6 (P=0.005 0), IL-10 (P=0.001 7), and IL-10RA (P=0.008 1) were statistically higher in muscle invasive group. Kaplan-Meier survival curve and multivariate Cox regression analysis showed that high IL-10RA expression was an independent predictive factor of IVRFS (P=0.044, HR=0.996, 95%CI: 0.992-0.998) in immunohistochemical cohort, which was confirmed in GSE134292 cohort (P=0.014, HR=0.515, 95%CI: 0.304-0.873).
CONCLUSION
The expression levels of AdipoQ, AdipoR1, IL-10, and IL-10RA were correlated with tumor stage, suggesting that these adipokines played important roles in tumor progression. IL-10RA was an independent predictor of IVRFS, suggesting that IL-10 and its receptor played a critical role in tumor recurrence.

3.Expert consensus of multi-disciplinary collaboration on bladder-preserving treatment for bladder cancer in China.
Chinese Journal of Oncology 2022;44(3):209-218
Objective: Bladder cancer is one of the most common malignant tumors in urology. Urothelial carcinoma accounts for about 90% of all bladder malignancies. According to whether the tumor invades the bladder muscle, it can be divided into non-muscle invasive bladder cancer and muscle invasive bladder cancer. Radical cystectomy is the standard treatment for muscle invasive bladder cancer patients and high-risk non-muscle invasive bladder cancer patients who have failed Bacillus Calmette-Guerin treatment. Due to the comorbidity of bladder cancer and the potential deterioration of the quality of life after surgery, many patients were not suitable or refused for radical cystectomy. Therefore, it is vital to find a bladder-preserving treatment that can achieve cure other than radical cystectomy. Bladder-preserving therapy that balances tumor control and quality of life serves as an alternative and supplement to radical cystectomy. This consensus is based on contemporary evidence-based medicine, combined with the native clinical practice of bladder preservation in a multidisciplinary treatment manner. To some extent, this consensus serves as a guidance for bladder-preservation therapy of bladder cancer in China. Several issues are extensively discussed here, including organizational structure and workflow of multidisciplinary treatment, the selection of patients for bladder-preserving therapy, treatment options and regimens, follow-up, as well as regimen choices of recurrence after bladder-preserving therapy.

BACKGROUND:
Accurate evaluation of lymph node metastasis in bladder cancer (BCa) is important for disease staging, treatment selection, and prognosis prediction. In this study, we aimed to evaluate the diagnostic accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) for metastatic lymph nodes in BCa and establish criteria of imaging diagnosis.
METHODS:
We retrospectively assessed the imaging characteristics of 191 BCa patients who underwent radical cystectomy. The data regarding size, shape, density, and diffusion of the lymph nodes on CT and/or MRI were obtained and analyzed using Kruskal-Wallis test and χ test. The optimal cutoff value for the size of metastatic node was determined using the receiver operating characteristic (ROC) curve analysis.
RESULTS:
A total of 184 out of 3317 resected lymph nodes were diagnosed as metastatic lymph nodes. Among 82 imaging-detectable lymph nodes, 51 were confirmed to be positive for metastasis. The detection rate of metastatic nodes increased along with more advanced tumor stage (P < 0.001). Once the ratio of short- to long-axis diameter ≤ 0.4 or fatty hilum was observed in lymph nodes on imaging, it indicated non-metastases. Besides, lymph nodes with spiculate or obscure margin or necrosis indicated metastases. Furthermore, the short diameter of 6.8 mm was the optimal threshold to diagnose metastatic lymph node, with the area under ROC curve of 0.815.
CONCLUSIONS
The probability of metastatic nodes significantly increased with more advanced T stages. Once lymph nodes are detected on imaging, the characteristic signs should be paid attention to. The short diameter > 6.8 mm may indicate metastatic lymph nodes in BCa.

PURPOSE: To examine the usefulness of various receptor tyrosine kinase expressions as prognostic markers and therapeutic targets in muscle invasive urothelial cancer (UC) patients. MATERIALS AND METHODS: We retrospectively analyzed the data of 98 patients with muscle invasive UC who underwent radical cystectomy between 2005 and 2010 in Yonsei Cancer Center. Using formalin fixed paraffin embedded tissues of primary tumors, immunohistochemical staining was done for human epidermal growth factor receptor 2 (HER2), fibroblast growth factor receptor 1 (FGFR1), and fibroblast growth factor receptor 3 (FGFR3). RESULTS: There were 41 (41.8%), 44 (44.9%), and 14 (14.2%) patients who have over-expressed HER2, FGFR1, and FGFR3, respectively. In univariate analysis, significantly shorter median time to recurrence (TTR) (12.9 months vs. 49.0 months; p=0.008) and overall survival (OS) (22.3 months vs. 52.7 months; p=0.006) was found in patients with FGFR1 overexpression. By contrast, there was no difference in TTR or OS according to the HER2 and FGFR3 expression status. FGFR1 remained as a significant prognostic factor for OS with hazard ratio of 2.23 (95% confidence interval: 1.27-3.90, p=0.006) in multivariate analysis. CONCLUSION: Our result showed that FGFR1 expression, but not FGFR3, is an adverse prognostic factor in muscle invasive UC patients after radical cystectomy. FGFR1 might be feasible for prognosis prediction and a potential therapeutic target after thorough validation in muscle invasive UC.

6.New and contemporary markers of prognosis in nonmuscle invasive urothelial cancer.
Korean Journal of Urology 2015;56(8):553-564
Nonmuscle invasive (NMI) urothelial cancer (UC) is associated with varied biological potential. It is characterized by frequent recurrence and progression, which thus worsens the oncological outcome. Nearly three-quarters of NMI UCs recur within 5 years, whereas half can progress during follow-up. Progression is particularly seen in T1 and carcinoma in situ (CIS). Undoubtedly, NMI UC is one of the most expensive cancers to manage. The European Organisation for Research and Treatment of Cancer (EORTC) risk calculator is a commonly used tool for assessing the recurrence and progression potential of a newly diagnosed cancer. The parameters used in the assessment are tumor size and number, pathological stage and grade of the cancer, presence of CIS, and prior recurrence rate. The main advantages of the EORTC tool are its ease of use and the lack of need to run expensive molecular tests. However, reproducibility of pathologic stage and grade is modest, which is a concern to clinicians. Molecular markers have potential for predicting the clinical outcome of NMI UC, given that clinico-pathologic variables are not sufficient for prediction of prognosis in an individual. Significant work has been done in the past 2 decades in understanding the molecular biology of bladder cancer; however, the translational value of this knowledge remains poor. The role for molecular markers in predicting recurrence seems limited because multifocal disease and incomplete treatment are probably more important for recurrence than the molecular features of a resected tumor. Urinary markers have very limited value in prognostication of bladder cancer and are used (mainly as an adjunct to cytology) for detection and surveillance of urothelial cell cancer recurrence. Prediction of progression with molecular markers holds considerable promise. Nevertheless, the contemporary value of molecular markers over clinico-pathologic indexes is limited.

OBJECTIVE: A prospective, randomized controlled trial was conducted to evaluate the efficacy of nerve-sparing radical hysterectomy (NSRH) in preserving bladder function and its oncologic safety in the treatment of cervical cancer. METHODS: From March 2003 to November 2005, 92 patients with cervical cancer stage IA2 to IIA were randomly assigned for surgical treatment with conventional radical hysterectomy (CRH) or NSRH, and 86 patients finally included in the analysis. Adequacy of nerve sparing, radicality, bladder function, and oncologic safety were assessed by quantifying the nerve fibers in the paracervix, measuring the extent of paracervix and harvested lymph nodes (LNs), urodynamic study (UDS) with International Prostate Symptom Score (IPSS), and 10-year disease-free survival (DFS), respectively. RESULTS: There were no differences in clinicopathologic characteristics between two groups. The median number of nerve fiber was 12 (range, 6 to 21) and 30 (range, 17 to 45) in the NSRH and CRH, respectively (p<0.001). The extent of resected paracervix and number of LNs were not different between the two groups. Volume of residual urine and bladder compliance were significantly deteriorated at 12 months after CRH. On the contrary, all parameters of UDS were recovered no later than 3 months after NSRH. Evaluation of the IPSS showed that the frequency of long-term urinary symptom was higher in CRH than in the NSRH group. The median duration before the postvoid residual urine volume became less than 50 mL was 11 days (range, 7 to 26 days) in NSRH group and was 18 days (range, 10 to 85 days) in CRH group (p<0.001). No significant difference was observed in the 10-year DFS between two groups. CONCLUSION: NSRH appears to be effective in preserving bladder function without sacrificing oncologic safety.

PURPOSE: The aim of our study was to assess the influence of perioperative blood transfusion (PBT) on survival outcomes following radical cystectomy (RC) and pelvic lymph node dissection (PLND). MATERIALS AND METHODS: We reviewed and analyzed the clinical data of 432 patients who underwent RC for bladder cancer from 1991 to 2012. PBT was defined as the transfusion of allogeneic red blood cells during RC or postoperative hospitalization. RESULTS: Of all patients, 315 patients (72.9%) received PBT. On multivariate logistic regression analysis, female gender (p=0.015), a lower preoperative hemoglobin level (p=0.003), estimated blood loss>800 mL (p<0.001), and performance of neoadjuvant chemotherapy (p<0.001) were independent risk factors related to requiring perioperative transfusions. The receipt of PBT was associated with increased overall mortality (hazard ratio, 1.91; 95% confidence interval, 1.25-2.94; p=0.003) on univariate analysis, but its association was not confirmed by multivariate analysis (p=0.058). In transfused patients, a transfusion of >4 packed red blood cell units was an independent predictor of overall survival (p=0.007), but not in cancer specific survival. CONCLUSIONS: Our study was not conclusive to detect a clear association between PBT and survival after RC. However, the efforts should be made to continue limiting the overuse of transfusion especially in patients who are expected to have a high probability of PBT, such as females and those with a low preoperative hemoglobin level and history of neoadjuvant chemotherapy.

PURPOSE: Transurethral resection of bladder tumor (TURBT) can be a challenging procedure for an inexperienced surgeon. We suggest an easy technique for TURBT, which we have named the "grasp and bite" technique. We describe this technique and compare its effectiveness and safety with that of conventional TURBT. MATERIALS AND METHODS: Monopolar TURBT (24-Fr Karl Storz) was performed in 35 patients who had superficial bladder tumors. After defining the tumor margin, the tumor and surrounding mucosa were grasped by use of a loop electrode and resectoscope sheath. With tight grasping, linear moving resection was performed. The patients' demographic, intraoperative, and postoperative data were analyzed between the conventional and grasp and bite TURBT groups. RESULTS: Of 35 patients, 16 patients underwent conventional TURBT (group 1), and the other 19 patients underwent grasp and bite TURBT (group 2). Both groups were similar in age, tumor multiplicity, size, anesthesia method, and location. Grasp and bite TURBT could be performed as safely and effectively as conventional TURBT. There were no significant differences in irrigation duration, urethral catheterization, postoperative hemoglobin drop, or length of hospital stay. No significant side effects such as bladder perforation, severe obturator reflex, or persistent bleeding occurred. There were no significant pathological differences between specimens according to the type of resection technique. CONCLUSIONS: The grasp and bite TURBT technique was feasible for superficial bladder tumors. It may be a good tool for inexperienced surgeons owing to its convenient and easy manner.

Korean Journal of Urology 2015;56(6):443-448
PURPOSE: To compare perioperative outcomes between running and interrupted vesicourethral anastomosis in open radical prostatectomy (RP). MATERIALS AND METHODS: The medical records of 112 patients who underwent open RP for prostate cancer at our institution from 2006 to 2008 by a single surgeon were retrospectively reviewed. Preoperative, intraoperative, and postoperative parameters were measured. RESULTS: Of 112 consecutive patients, 62 patients underwent vesicourethral anastomosis by use of the running technique, whereas 50 patients underwent anastomosis with the interrupted technique. The groups did not differ significantly in age, body mass index, prostate-specific antigen, prostate volume, or pathologic findings. The intraoperative extravasation rate was significantly lower in the running group (8.1% vs. 24.0%, p=0.01). The mean anastomosis time was 15.1+/-5.3 and 19.3+/-4.6 minutes in the running and interrupted groups, respectively (p=0.04). The rates of postoperative extravasation were similar for both groups (6.4% vs. 10.0%, p=0.12). The duration of catheterization was significantly shorter in the running group (9.0+/-3.0 days vs. 12.9+/-6.4 days, p<0.01). The rate of urinary retention after catheter removal and the rate of bladder neck contracture were not significantly different between the two groups. The rate of urinary continence at 3, 6, 9, and 12 months after RP was also similar in both groups. CONCLUSIONS: Both anastomosis techniques provided similar functional results and a similar rate of postoperative urine extravasation. However, running vesicourethral anastomosis decreased the rate of intraoperative extravasation and time for anastomosis, without increasing the risk of urinary retention or bladder neck contracture.
