Abstract
Background Bladder carcinoma ranks tenth among all cancers worldwide predominantly affecting elderly males. Common risk factors being cigarette smoke and aniline dyes. Immunohistochemical markers play a pivotal role for its diagnosis and prognosis. Aim To analyze the immunohistochemical expression of p53, CD10, Ki-67 in bladder cancers correlating with demographic features, pathological grade, and stage and to establish as prognostic biomarkers. Materials and Methods Surgical samples of total of 70 cases of bladder tumor were collected, processed, stained in routine hematoxylin and eosin followed by immunohistochemistry of p53, CD10, and Ki67 markers performed on randomly selected 30 cases only. Results Out of 70 cases 69 cases (98.6%) were carcinomas; urothelial carcinoma being 71.4% (n = 50) with male: female ratio = 7.7:1 and mean age = 61.81 ± 12.83 years. Out of 30 cases, p53 was positive in 50% of cases, 30% - negative and 20% - equivocal. p53 positive expression pattern was more in high grade (HG) than low grade (LG). Significant difference was observed in the mean p53 scoring (%) and different stages (P = 0.043). CD10 expression was negative in 56.6%, (1+) in 16.6%, and (2+) in 26.6% of cases and significant difference in CD 10 expression was observed between the high and LG (P = 0.001). Ki-67 labeling index was appreciably higher in HG than the LG tumor (32.49% ± 24.35%; 6.86% ± 8.1%). Majority of Ki-67 expression was observed in stage pT2, followed by the pT1 stage. Conclusion Cocktail of p53, CD10, and Ki67 is useful as potential prognostic markers in bladder cancers.

Abstract
Bone scintigraphy with Tc-99m-diphosphonate analogs are widely used in staging, restaging, and monitoring the therapy effectiveness of various cancer types. Bone-seeking agents are excreted through urination, resulting in the visualization of either anatomical abnormalities or pathological conditions of the kidneys and bladder. We present a case of a 63-year-old man with urinary bladder carcinoma depicted on whole body planar and single-photon emission computed tomography/computed tomography images.

Abstract
Lymphoepithelioma-like carcinoma (LELC) was characterized by epithelial neoplastic cells developing in solid or incohesive sheets mixed with a noticeable lymphoid infiltration. Lymphoepithelioma-like carcinoma of the bladder (LELCB), which was first described by Zukerberg, is a rare variant of LELC. Here we reported a new case of LELCB occurring in a 70-year-old woman presenting with hematuria. Computed tomography (CT) and cystoscopy revealed a tumor on the left upper wall of the bladder. A partial cystectomy was finally performed. Pathological and immunohistochemical analysis revealed LELCB. After receiving systemic adjuvant chemotherapy, the patient conducted a 25-month follow-up without experiencing a recurrence.

Abstract
BACKGROUND Urinary bladder cancer is an uncommon cancer in females. Despite not being an infrequent encounter, female bladder cancer remains a poorly defined entity. There is a paucity of literature regarding bladder cancer in females, especially in North India. OBJECTIVE This study aims to evaluate the clinico-pathological profile of bladder cancer in female patients managed at a single centre in north India. MATERIALS AND METHODS This retrospective observational study was carried out in a tertiary care centre in North India. Medical records and a database of female patients with bladder cancer treated between January 2012 and January 2021 were retrieved. Data regarding age, duration of disease, associated comorbidity, histopathological variants, and outcomes were studied. RESULTS Out of 56 female patients with bladder masses, 55 had transitional cell carcinoma (TCC), while one had pheochromocytoma. Painless hematuria (80.3%) was the commonest presentation. At the time of presentation, 5 patients (9.1%) had muscle-invasive bladder cancer (T2-T4), while 50 patients had non-muscle-invasive disease, out of which 31 (56.4%) patients had high-grade and 19 (34.5%) patients had low-grade papillary carcinoma. Twenty-three patients (41.8%) had a history of exposure to domestic chulha (open wood-burning cooking stove), and 11 patients (20%) were smokers; six patients (10.9%) were exposed to both risk factors. CONCLUSIONS Female bladder cancer was most prevalent in the sixth decade of life, with the majority of patients having a high-grade but non-muscle-invasive disease. Of all the risk factors, chulha exposure was the main risk factor in the aetiology of female bladder cancer.

Abstract
INTRODUCTION Urinary bladder cancer is a serious oncological problem that is the cause of many deaths worldwide. The processes of metastasis and origination of local tumor invasion depend on the extracellular matrix (ECM) degradation. The cancer microenvironment, particularly the ECM, may be considered a key factor in cancer progression. Matrix metalloproteinases (MMPs) are classified as the main factors responsible for the degradation of ECM components. Therefore, the aim of the study was to evaluate the expression and activity of matrix metalloproteinase 2 and 9 (MMP-2 and MMP-9) in urinary bladder cancer according to different stages. MATERIAL AND METHODS Urinary bladder tissue samples were analyzed. Cancer patients were divided into two groups: low-grade tumors (LG; Group I) and high-grade tumors (HG; Group II). Control tissue was obtained from the opposite site to the tumor. MMPs content and activity (actual and specific) were evaluated using ELISA and Western blot methods, respectively. RESULTS Both MMPs are present in high and low molecular complexes in healthy or bladder cancer tissues. The content of MMP-9 is enhanced in comparison with MMP-2, particularly in HG cancer tissue. The actual activity of MMP-2 was highest in LG cancer tissue whereas the actual activity of MMP-9 was highest in HG cancer. Specific activity of both MMPs was highest in LG cancer, but the activity of MMP-9 was higher in comparison with MMP-2. CONCLUSIONS In conclusion, the content and specific activity of MMP-9 were increased in comparison with MMP-2. The revealed differences in content and activity of both MMPs demonstrate their different participation in ECM remodeling at different stages of cancer development. Moreover, it seems that MMP-9 has higher clinical utility than MMP-2 as a potential therapeutic option and a diagnostic biomarker of urinary bladder cancer.

Abstract
Introduction Tobacco use, especially cigarette smoking, is a well-documented risk factor for cancer; however, its specific effect on bladder cancer has not been clearly defined. This study aimed to determine the association between tobacco use and bladder cancer in a South Asian population. Materials and methods We conducted a retrospective review of the medical records of 64 patients diagnosed with bladder tumors from February 2018 to March 2020. Patients included in the study were surveyed via a questionnaire regarding tobacco use. All patients received transurethral resection of the bladder tumor, and we analyzed histopathological and clinical outcomes. Results Our study population’s median age was 57 years, and the study included twice as many male patients as female patients. Most patients (n=45; 70%) reported not using tobacco products, and 19 patients (30%) reported tobacco use. Thirty-five of 45 nontobacco users (78%) had high-grade cancer, and 10 (22%) had low-grade cancer. Among the tobacco users, 10 (52%) had high-grade cancer, and nine (48%) had low-grade cancer. Conclusions According to our findings, a substantial cohort of bladder cancer patients is not tobacco users, and high-grade bladder cancer was more common to people who are not tobacco users. Other environmental factors play a key role in developing bladder cancer in our South Asian study population. Prevention efforts should focus on reducing bladder cancer risk factors.

Abstract
Human urinary bladder cancer is a huge worldwide oncological problem causing many deaths every year. The degradation of extracellular matrix (ECM) induced by molecules such as matrix metalloproteinases (MMPs) is one of the main factors influencing the process of metastasis origination. The MMP expression is tied to tumor aggressiveness, stage, and patient prognosis. The cleavage of constituent proteins is initiated and prolonged by matrix metalloproteinases, such as MMP-3 and MMP-10. The aim of this study was to evaluate the expression and activity of both MMPs in human urinary bladder cancer occurring at various stages of the disease. Tissue samples from patients with urinary bladder cancer were analyzed. Samples were collected from patients with a low- and high-grade cancer. Control tissue was collected from the site opposite to the tumor. DNA content, MMPs content, and activity of MMP-3 and MMP-10 were measured using ELISA and Western blot techniques. MMP-3 and MMP-10 occur in high molecular complexes in human urinary bladder in healthy and cancerous tissues. Particularly, in high-grade tumors, the content of MMP-10 prevails over MMP-3. The actual and specific activities vary in both grades of urinary bladder cancer; however, the highest activity for MMP-3 and MMP-10 was found in low-grade tissues. In conclusion, MMP-10 had a higher content, but a lower activity in all investigated tissues compared to MMP-3. Generally, obtained results demonstrated a contrary participation of MMP-3 and MMP-10 in ECM remodeling what may be crucial in the pathogenesis of human urinary bladder carcinoma.

Abstract
Molecular subtyping of urothelial carcinoma (UC) is similar to that of breast cancer and is based on the developmental biology approach. The aim of the present study is to assess the prognostic impact of CK5, CK14, and CK20 expression in urinary bladder cancer (UBC) with the potential to stratify them into different subtypes. The current study examined the immunohistochemical expression of CK5, CK14, and CK20 in 90 specimens of UBC. CK5 was expressed in 81.1% of the cases and was significantly associated with old age, muscle invasion, presence of bilharziasis, and tendency for poor overall survival. CK20 was expressed in 47.8% of the cases and was associated with nonmuscle invasion and pure UC while 50% of the cases expressed CK14 that were associated with muscle invasion and perineural invasion. Most squamous cell carcinoma and those associated with bilharziasis were belonged to Ck5+/CK20- subgroup while pure UC and those lacked bilharziasis were located in the Ck5+/CK20+ subgroup. The basal group (Ck5+/CK14+/CK20-) showed high proliferative features compared to the intermediate group (Ck5+/CK14-/CK20-). Generally, presence of CK5 is associated with adverse features especially in the group lacking CK20; however, basal and intermediate subgroups share CK5 expression but they show different proliferative capacities, so their distinction by CK14 is helpful.

Abstract
BACKGROUND Human urinary bladder cancer is one of the most common cancers worldwide with the mortality rate of approximately 165,000 people annually. The modulation of extracellular matrix is a crucial event in the metastatic spread, among others in angiogenesis. It is initiated and prolonged by the cascade of matrix metalloproteinases. MMP-14 and MMP-15 are associated with a high degree of malignancy, aggressiveness, and survival prognosis by the activation of other matrix metalloproteinases (MMPs). This study was aimed at evaluating the expression and the activity of selected transmembrane metalloproteinases at different stages of human urinary bladder cancer. METHODS Western blot and enzyme linked immunosorbent assay (ELISA) method were used to evaluate the expression and content of MMPs and TIMP-1. The activity of studied enzymes was determined with fluorometric method. RESULTS Both transmembrane metalloproteinases are found in healthy or cancerous tissue in high molecular complexes of human urinary bladder. MMP-14 dominates over MMP-15, particularly in high-grade urinary bladder cancer. Their contents significantly change with the grade of bladder tumor. The amount of MMP-14 increases with increasing grade of tumor. MMP-15 content decreases in high-grade bladder cancer. With increasing grade of urinary bladder cancer their actual activity (per kg of total protein content) is varying in different ways. In all examined tissues, the specific activity of MMP-15 (per kg of the enzyme content) is much higher in comparison to MMP-14. Human urinary bladder cancer contains higher TIMP-1 amounts than control tissue but with the decrease with an increase in tumor grade. CONCLUSION Comparison of investigated enzymes' activity and the inhibitor content suggests it opposite effects, higher suppression of MMP-14 than MMP-15 activity in low-grade bladder cancer and reverse TIMP-1 action in high-grade cancer. The MMP-14 activity determination in urinary bladder cancer tissue may be used as a predictor of a risk of metastasis.

Abstract
OBJECTIVE To investigate the clinical feasibility and effect of nerve-sparing robot-assisted laparoscopic radical cystectomy (NSRA-LSRC). METHODS We retrospectively reviewed the clinical data on 12 cases of NSRA-LSRC performed from March 2016 to May 2018. The patients were aged 45 to 65 years old and all potent before surgery, with a mean IIEF-5 score of >17. The surgical procedure involved excision of the bladder and prostate and dissection of the pelvic lymph nodes, with preservation of the bilateral neurovascular bundles, internal accessory pudendal artery and pubic bladder complex. All the patients were advised to take PDE5I postoperatively and followed up for the sexual function with the IIEF-5 scores. RESULTS Surgical procedures were completed successfully, all with negative surgical margins. Postoperative pathology confirmed invasive high-grade urothelial carcinoma or carcinoma in situ in all the cases, including 11 cases in stage T2N0M0 or below and 1 case in stage T3aN0M0. There were no serious intraoperative or postoperative complications, nor recurrence or metastasis during the follow-up period of 12-36 (20.7 ± 8.0) months. The IIEF-5 scores of the patients at 3, 6 and 12 months after operation were 10.9 ± 6.9, 12.3 ± 6.9 and 14.1 ± 8.0, respectively. At 12 months, satisfactory sexual intercourse was achieved with the help of potency-enhancing medicine in 5 cases (41.7%), penile erection insufficient for sexual intercourse in 3 cases (25%), and no erection in 4 cases (33.3%). CONCLUSIONS Nerve-sparing robot-assisted laparoscopic radical cystectomy can maximally preserve the sexual function of the patients with urinary bladder carcinoma.

Abstract
BACKGROUND Pressurized aerosol chemotherapy (PAC) is a novel approach to the treatment of surface malignancies. This study aimed to investigate whether PAC is a feasible treatment of early-stage bladder cancer. MATERIALS AND METHODS PAC via inserted microcatheter was performed on a fresh urinary bladder in a post-mortem swine model (n=3), creating a pressurized doxorubicin chemoaerosol. Drug penetration of aerosolized doxorubicin at different concentrations (3 mg/50 ml, 9 mg/50 ml and 15 mg/50 ml) and different locations on the mucosa was measured via fluorescence microscopy. RESULTS Mean endoluminal penetration rates for the urothelium following PAC reached 149±61 μm (using 15 mg/50 ml). Doxorubicin penetration was significantly increased with higher drug concentration (15 vs. 3 mg/50 ml: p<0.01). This study demonstrated the feasibility of PAC for intravesical use. CONCLUSION PAC is a feasible minimally-invasive approach to the treatment of early-stage bladder cancer.

Abstract
Objective To compare the sensitivity, specificity, positive predictive value, negative predictive value of urinary survivin and that of urine cytology in the diagnosis of bladder carcinoma in a schistosoma endemic area. Design and setting This is a 12-month prospective study of patients with features of bladder carcinoma as study group and patients with other urologic conditions and healthy volunteers as control group. Participants Patients with features of bladder carcinoma formed the study group, while patients with other urological conditions and healthy volunteers formed the control group. Results There were 52 patients in study group and 36 patients in control group. The mean ages of patients in the study and control groups were 47.17 ± 17.00 and 44.19 ± 18.89 years respectively. There were 48 males and 4 females in the study group, giving a male: female ratio of 12:1. Thirty-one (60 %) of the patients were farmers and 44 patients (85%) had history suggestive of schistosomiasis at childhood. The sensitivity of urine cytology and survivin in the study were 29.1% and 100.0% respectively. The specificity of urine cytology and survivin were 100.0% and 100.0% respectively (p= 0.05). The marker was associated with false positive (FP) results in patients with prostate cancer. Conclusion Urinary survivin is highly sensitive, specific and predictive of bladder carcinoma in our environment. The marker is associated with false positive results in patients with prostate cancer. Funding By authors.

Abstract
Paget's disease of the vulva is a rare intraepithelial neoplasm, accounting for <5% of all vulvar lesions. The underlying mechanisms of this disease are still poorly understood, however, diagnosing a Pagetoid lesion early is of prime importance as it may forewarn an underlying systemic malignancy. We discuss the case of an elderly female who was being conservatively treated for infectious lesion of the lower urinary tract and vulva for months. She was subsequently confirmed on histopathology with vulvar Paget's and underlying urothelial carcinoma, with the help of an extensive panel of immunohistochemistry.

Abstract
Expression of interleukin-23 receptor (IL-23R) and IL-17 in urinary bladder carcinoma (UBC) was investigated to explore the correlations with prognosis. IL-23/IL-17 axis significantly inhibited the development of inflammatory bowel disease. Thirty patients with UBC were enrolled in Zhengzhou Central Hospital Affiliated to Zhengzhou University from September 2013 to September 2014. Tumor tissue and adjacent healthy tissue were collected, and the levels of IL-23R and IL-17 mRNA were detected by RT-PCR. Thirty healthy people were also selected to serve as normal control group. Serum levels of IL-23R and IL-17 in serum of UBC patients and normal controls were detected by ELISA, and the correlations with clinical features of UBC were analyzed. Pearson's correlation analysis was used to analyze the correlation between IL-23R and IL-17 protein expression. Follow-up study was performed by phone or during patient's visit to out-patient department. Overall survival (OS) and disease-free survival (DFS) curves were plotted by Kaplan-Meier method to analyze the correlation between expression of IL-23R and IL-17 and survival time. ROC curve was used to detect the diagnostic values of IL-23R and IL-17 protein for UBC. Levels of IL-23R and IL-17 mRNA in UBC tissue were 3.26 and 2.65 times higher than those in adjacent tissue (P<0.05), and serum levels of IL-23R and IL-17 protein in UBC patients were significantly higher than those in normal control group. Protein expression levels of IL-23R and IL-17 were correlated with clinical stage and lymph node metastasis in UBC patients (P<0.05), and Cox hazard model showed that L-23R and IL-17 expression may be independent factors for UBC (P<0.05), and high expression levels of IL-23R and IL-17 significantly shortened the OS and DFS (P<0.05). Serum levels of IL-23R and IL-17 can be used to effectively diagnose clinical stage and lymph node metastasis of UBC patients, and the combined diagnosis has a higher sensitivity and specificity than the diagnosis using a single factor. These findings indicated that expression levels of IL-23R and IL-17 were increased in tumor tissue and serum of UBC patients, and the increased expression levels of IL-23R and IL-17 were correlated with poor prognosis. Detection of IL-23R and IL-17 levels has certain clinical significance in the diagnosis and prognosis of UBC.

Abstract
Secondary rectal linitis plastica is a very rare malignancy with poor prognosis. Diagnosis is difficult because of nonspecific clinical and endoscopic findings and negative biopsies in most cases owing to the fact that the mucosa is frequently unaffected. We herein describe a 68-year-old man who presented with a six-month history of tenesmus and constipation. Endoscopy revealed a narrow distal rectum with an indurated, cobblestone appearance of mucosa. Multiple biopsies and fine-needle aspiration were negative for malignancy. Abdominal MRI and transrectal ultrasonography showed findings compatible with rectal linitis plastica. He underwent rectal extirpation with total cystectomy and lymph nodes dissection. Histology demonstrated secondary rectal linitis plastica due to a poorly differentiated urinary bladder carcinoma. We emphasize the endoscopic and endosonographic features and the difficulty to establish a preoperative diagnosis of secondary rectal linitis plastica.

Abstract
Objective: To evaluate the expression pattern of epidermal growth factor receptor (EGFR) in urinary bladder cancer and its association with human epidermal growth factor receptor 2 (HER2), epidermal growth factor (EGF), interleukin-6 (IL-6), and high risk human papilloma virus (HPV) types 16 and 18. Materials and Methods: Thirty cases of urothelial carcinoma were analyzed. EGFR, HER2, EGF, and IL-6 expressions in the tissue were evaluated by immunohistochemical staining. For HPV, DNA from tissue samples was extracted and detection of HPV was done by PCR technique. Furthermore, evaluation of different intracellular molecules associated with EGFR signaling pathways was performed by the western blot method using lysates from various cells and tissues. Results: In this study, the frequencies of immunopositivity for EGFR, HER2, EGF, and IL-6 were 23%, 60%, 47%, and 80%, respectively. No cases were positive for HPV-18, whereas HPV-16 was detected in 10% cases. Overall, expression of EGFR did not show any statistically significant association with the studied parameters. However, among male patients, a significant association was found only between EGFR and HER2. Conclusions: Overexpression of EGFR and/or HER2, two important members of the same family of growth factor receptors, was observed in a considerable proportion of cases. Precise knowledge in this subject would be helpful to formulate a rational treatment strategy in patients with urinary bladder cancer.

Abstract
We report the imaging findings of a patient with Paget's disease in metastatic carcinoma bladder evaluated by Tc99m-Methylene diphosphonate (MDP) bone scintigraphy, F18-Fluoride positron emission tomography/computed tomography (PET/CT) and F18-fluorodeoxy glucose (FDG) PET/CT. Tc99m-MDP bone scan showed intense uptake in the skull bones without any other abnormal tracer distribution. F18-Fluoride PET/CT revealed intense uptake in the pelvic bones along with skull bones, but F18-FDG PET/CT showed intense multifocal FDG uptake in the bladder and bilateral inguinal lymph nodes, with no abnormal uptake in the skull bones. CT images showed thickening of skull bones.

Abstract
AIMS To evaluate whether in situ biomarkers Ki67, mitotic activity index (MAI), p53, mean area of the 10 largest nuclei (MNA10), and whole genome DNA ploidy by flow and image cytometry (FCM and ICM, respectively) have independent prognostic value in urinary bladder urothelial cell carcinomas (UCs). METHODS Ki67 and p53 immunoquantitation was performed in TaT1 consensus diagnosis UCs. MAI and MNA10 were also determined. Single cell suspensions were stained (DAPI for FCM; Feulgen for ICM). There was enough material for all measurements in 171 cases. Kaplan-Meier curves and multivariate survival analysis (Cox) were used to assess the prognostic value of all features (including classic clinicopathological risk factors, such as stage, grade, multicentricity, carcinoma in situ). RESULTS Thirteen (7.6%) patients progressed. Of the classic factors, grade was strongly prognostic in univariate analysis, as were all the biomarkers. In multivariate analysis, the strongest independent combinations for progression were MNA10 (threshold (T) = 170.0 micro m(2)) plus MAI (T = 30), or MNA10 (T = 170.0 micro m(2)) plus Ki67(T = 25.0%). p53 (T = 35.2%) plus Ki67 (T = 25.0%) also predicted progression well, with high hazard ratios, but p53 measurements were not as reproducible as the other features. The prognostic value of the quantitative biomarkers exceeded that of the classic risk factors and DNA ploidy. The sensitivity, specificity, positive, and negative predictive values of MNA10/MAI or MNA10/Ki67 at the thresholds mentioned were 100%, 79%, 57%, and 100%, respectively. These feature combinations were also strongest prognostically in the high risk treatment subgroup. CONCLUSIONS The combined biomarkers MNA10/Ki67 or MNA10/MAI are more accurate and reproducible predictors of stage progression in TaT1 UCs than classic prognostic risk factors and DNA ploidy.

Abstract
The effects of the non-steroidal anti-inflammatory drug (NSAID) piroxicam and the carotenoids lycopene and beta-carotene, alone or in combination, on the development of rat superficial urinary bladder carcinomas induced by N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) were studied. Male Fischer 344 rats, 6 weeks old, were given 0.05% BBN in the drinking water for 8 weeks followed by administration of piroxicam (0.0075% in the diet), lycopene (0.0025% in the drinking water) and/or beta-carotene (0.0025% in the drinking water) for 12 weeks, then killed for histological analysis of urinary bladder lesions. Cell proliferation potential was analyzed by immunohistochemical staining of the proliferative cell nuclear antigen (PCNA). Piroxicam alone, piroxicam+lycopene, and piroxicam +lycopene+ beta-carotene all significantly decreased the incidences and numbers of transitional cell carcinomas (TCCs), but the combination of piroxicam with carotenoids did not result in a clear improvement in the preventive potential of piroxicam. Piroxicam+ beta-carotene also caused a significant reduction and lycopene alone a slight but not significant reduction in the number of TCCs. In contrast, beta-carotene alone and lycopene+ beta-carotene were without inhibitory influence on any of the lesion categories examined, and the latter significantly increased the proportion of high-grade TCCs. Nevertheless, all of the chemopreventive agents, either alone or in combination, significantly decreased the TCC PCNA index, the effect extending to the surrounding epithelium in the piroxicam+lycopene and piroxicam+lycopene+beta-carotene groups. These results indicate that the NSAID piroxicam may be a more effective chemopreventive agent than lycopene and beta-carotene for superficial urinary bladder carcinogenesis.
