Urothelial Tumors

Context.—Urothelial tumors are rare in young patients. Because of their rarity, the natural history of the disease in young patients remains poorly understood. Objective.—To understand the pathologic and clinical features of urothelial tumors of the urinary bladder in young patients. Design.—We identified 59 young patients with urothelial tumors of the urinary bladder treated at our institution and analyzed the tumors' pathologic features and the patients' clinical outcomes. Results.—All patients were 30 years or younger, with a mean age of 23.5 years (range, 4–30). Thirty-eight patients (64%) were male, and 21 (36%) were female. Most tumors were noninvasive, papillary urothelial tumors (49 of 59; 83%), including papillary urothelial neoplasms of low malignant potential (7 of 49; 14%), low-grade papillary urothelial carcinomas (38 of 49; 78%), and high-grade papillary urothelial carcinomas (4 of 49; 8%). Only a few (n = 10) of the urothelial tumors were invasive, invading the lamina propria (n = 5; 50%), muscularis propria (n = 4; 40%), or perivesical soft tissue (n = 1; 10%). Clinical follow-up information was available for 41 patients (69%), with a mean follow-up time of 77 months. Of 31 patients with noninvasive papillary urothelial tumors, only 1 patient (3%) later developed an invasive urothelial carcinoma and died of the disease, and 30 of these patients (97%) were alive at the end of follow-up, although 10 (32%) had local tumor recurrences. In the 10 patients with invasive urothelial carcinomas, 3 patients (30%) died of the disease and 5 others (50%) were alive with metastases (the other 2 [20%] were alive with no recurrence). Conclusion.—Urothelial tumors in young patients are mostly noninvasive, papillary carcinomas and have an excellent prognosis; however, a small subset of patients may present with high-grade invasive urothelial carcinomas that result in poor clinical outcomes.

BACKGROUND: Urinary bladder cancer is second most common cancer after prostate cancer in the genitourinary system. Urothelial Carcinoma is the commonest tumour type accounting for 90% of all primary tumours of the bladder Histopathological analysis of cystoscopic bladder biopsy and Transurethral resection of the bladder tumour (TURBT) material are the mainstay for cancer diagnosis. This study was aimed to determine the frequency of different types of neoplastic lesions of the urinary bladder and to determine the grade and stage of urothelial tumours. MATERIAL METHOD: The study was carried out in the Department of Pathology, Rajendra Institute of Medical Sciences (RIMS), Ranchi from January 2018 to June 2020 and included 30 cases of cystoscopic biopsies and TURBT specimens. RESULTS: Out of 30 cases of neoplastic lesions, majority were of high grade papillary urothelial carcinoma (n=14, 46.67%) followed by low grade papillary urothelial carcinoma (n=9, 30%), 3 cases (10%) were of PUNLMP, 2 cases (6.66%) of papilloma and 1 (3.33%) case each of moderately differentiated squamous cell carcinoma and extra nodal NHL. The most common age group was 41-50 years and 51-60 years with 9 (30%) cases each. Muscle invasion was seen only in high grade papillary urothelial carcinomas. CONCLUSION: High-grade urothelial carcinomas with lamina propria and muscle invasion are the most common neoplastic lesion of urinary bladder with significant morbidity and mortality. Muscle invasion and grading, as per TNM staging, are valuable prognostic factors.

Background: Urinary bladder cancer is an important cause of morbidity and mortality due to urological conditions. It is tenth most common cancer overall in both sexes. It is seventh most common cancer overall and second most common cancer of genitourinary tract in males. Ninety five percent of bladder tumors are epithelial and the rest are mesenchymal, of which majority are primary urothelial tumors. Urothelial tumors are classified into infiltrating urothelial carcinoma with its variants and non-invasive urothelial neoplasias. Tumor stage is the strongest prognostic parameter.Aims and Objectives: The current study was designed with an aim to elucidate the histologic pattern of bladder tumors and observe whether any association between histologic grade and muscle invasion exists.Materials and Methods: This descriptive study was carried out on 84 cases of urinary bladder tumors received in Department of Pathology, College of Medical Sciences and Teaching Hospital during a time period of 5 years from January 2012 to December 2016.Results: The mean ± SD of age of presentation was 63±13 years with a male female ratio 3.2:1. Ninety-five percent cases were primary epithelial tumors and 93% cases were of urothelial origin. Low grade papillary urothelial carcinoma was the most common urothelial tumor (40.5%) followed by high grade papillary urothelial carcinoma (34.5%). Some rare types like primary adenocarcinoma and small cell carcinoma were also seen in this study (1.2% each). Muscle invasion was significantly higher in high grade (66%) as compared to low grade papillary urothelial carcinoma (3%). Muscle tissue was absent in 8 (9.5%) cases.Conclusion: There is relationship of histologic grade with aggressiveness of tumor. Most of the high grade tumors are muscle invasive at presentation. Submission of muscle tissue is important for optimal patient management.Asian Journal of Medical Sciences Vol.9(6) 2018 45-50

Background: It has been speculated that the patellar J sign may have a negative effect on the clinical outcomes of patients with recurrent patellar dislocation (RPD). Purpose: To (1) evaluate clinical outcomes, postoperative patellar stability, and patellar maltracking correction in patients with RPD treated with derotational distal femoral osteotomy (DDFO) and combined procedures and (2) investigate the influence of J sign severity on the clinical outcomes. Study Design: Cohort study; Level of evidence, 3. Methods: Between January 2015 and December 2016, a total of 78 patients (81 knees) with RPD, a positive J sign, and an excessive femoral anteversion angle (FAA; ≥30°) were surgically treated with DDFO and combined procedures. J sign severity was graded according to a previously described classification system (grades 1-3). Routine radiography and computed tomography were performed on every patient to evaluate the patellar height, trochlear dysplasia, genu valgum, tibial tuberosity–trochlear groove distance, patellar lateral tilt angle, and patella–trochlear groove distance. The patellar lateral shift distance during stress radiography was measured preoperatively and postoperatively to quantify medial patellofemoral ligament (MPFL) graft laxity under anesthesia, and “MPFL residual graft laxity” was defined as the patellar ridge surpassing the apex of the lateral femoral trochlea. Patients were evaluated using the Kujala, International Knee Documentation Committee (IKDC), and Lysholm scores preoperatively and postoperatively. Patients were allocated into 3 subgroups in terms of the severity of the J sign: low-grade group 1 (grade 1; n = 19), low-grade group 2 (grade 2; n = 16), and high-grade group (grade 3; n = 12). Subgroup analyses were performed to investigate the influence of a high-grade J sign on the clinical outcomes. Results: Among the 78 patients (81 knees), 47 patients (47 knees) met the inclusion criteria. The mean follow-up time was 26.1 ± 1.7 months. The mean preoperative and postoperative FAAs were 36.2°± 5.3° and 10.0°± 2.1°, respectively, with a mean correction angle of 26.2°± 5.9°. At the final follow-up, all patient-reported outcomes improved significantly, and subgroup analyses showed that the high-grade group had significantly lower Kujala scores (75.6 vs 85.3 for low-grade group 1 [ P < .001] and 83.4 for low-grade group 2 [ P = .001]), Lysholm scores (77.6 vs 84.6 for low-grade group 1 [ P = .003]), and IKDC scores (78.6 vs 87.3 for low-grade group 1 [ P = .001] and 84.3 for low-grade group 2 [ P = .033]) than the low-grade groups. The total rate of MPFL residual graft laxity was 8.5% (4/47), and the prevalence of the postoperative residual J sign was 38.3% (18/47). Subgroup analyses showed significant differences between the high-grade group and the 2 low-grade groups with regard to the MPFL residual graft laxity rate (33.3% vs 0.0% for low-grade group 1 [ P = .016] and 0.0% for low-grade group 2 [ P = .024]), residual J sign rate (91.7% vs 15.8% for low-grade group 1 [ P < .001] and 25.0% for low-grade group 2 [ P < .001]), and patellar lateral shift distance (14.2 vs 8.1 mm for low-grade group 1 [ P = .002] and 8.7 mm for low-grade group 2 [ P = .007]). Conclusion: In a group of patients treated for RPD with a positive preoperative J sign and increased FAA (≥30°), patients with a preoperative high-grade J sign had inferior clinical outcomes, more MPFL residual graft laxity, and greater residual patellar maltracking.

Abstract Background.—Primary cardiac leiomyosarcomas are rare. Isolated reported cases and small series generally describe spindle-celled, high-grade tumors with poor short-term survival; however, the pathologic features of many of these tumors are incompletely documented. The authors report in detail the clinicopathologic features of 2 relatively low-grade epithelioid and spindle-celled primary cardiac leiomyosarcomas. Methods.—Cases 1 and 2 were studied using standard histochemical and immunohistochemical techniques, and case 1 was examined by electron microscopy. The literature was reviewed with regard to primary cardiac leiomyosarcomas. Results.—Both tumors showed epithelioid and spindle-celled areas. The tumor in case 1 was low grade, and the tumor in case 2 was predominately low grade with a high-grade focus. A review of 28 reported cases revealed a wide age range (mean, 43 years), equal male-to-female ratio, and a predilection for the left atrium (48%). Follow-up of reported cases with fewer than 5 mitoses per 10 high-power fields showed a mean survival of 22 months compared with a 9-month mean survival for all others. Conclusions.—Short-term follow-up of reported cases of high-grade cardiac leiomyosarcoma suggests a poor prognosis. Long-term follow-up in our case 2, along with follow-up of reported cases that were histologically similar to our cases, suggests that cardiac leiomyosarcomas with low-grade features or mixed low- and high-grade features also have a poor overall long-term survival, with a high rate of local recurrence and systemic spread.

Overweight Or Obesity

Background:Obesity population are rising rapidly and have become a major health issue. Studies have shown that obesity is a low-grade inflammatory status characterized by increase in proinflammatory cytokines.Objectives:To examine the impact of overweight or obesity on disease activity and treatment responses to biologics in patients with ankylosing spondylitis (AS) in a real-world setting.Methods:Body mass index (BMI) is available in 1013 patients from the Chinese Ankylosing Spondylitis Imaging Cohort (CASPIC). Differences in clinical outcomes (such as BASDAI, ASDAS, BASFI, and ASAS HI) and treatment responses to biologics (ΔBASDAI and ΔASDAS) over 3, 6, 9, and 12 months are assessed between BMI categories (normal weight BMI <24 kg/m2; overweight BMI=24-28 kg/m2; obesity BMI ≥28 kg/m2) using Kruskal-Wallis test. The association between BMI and clinical characteristics and treatment responses to biologics was determined, and multivariate median regression analyses were conducted to adjust for confounders (such as age, gender, smoke, and HLA-B27).Results:Among 1013 patients with AS, overweight accounts for 33%, while obesity for 12.4%. There were significant differences between patients who were obese or overweight and those with a normal weight regarding clinical outcomes (BASDAI: 2.90/2.56 vs 2.21; ASDAS-CRP: 2.20/1.99 vs 1.81; BASFI: 2.13/1.69 vs 1.38; ASAS HI: 6.87/5.29 vs 5.12 and BASMI: 2.35/1.76 vs 1.62; all P<0.05). After adjusting for age, gender, smoke, and HLA-B27, obesity remained associated with higher disease activity (BASDAI: β=0.55, P=0.005; ASDAS-CRP: β=0.40, P<0.001), poorer functional capacity (BASFI: β=0.58, P=0.001), worse health index (ASAS HI: β=1.92, P<0.001) and metrology index (BASMI: β=0.71, P=0.013). For TNFi users, BMI was found to be negatively correlated with changes in disease activity (ΔBASDAI and ΔASDAS) in the multivariate regression model (all P<0.05), and overweight and obese patients showed an unsatisfactory reduction in disease activity during 3-month, 6-month, 9-month, and 12-month follow-up period, compared to normal weight patients (all P<0.05).Conclusion:Overweight or obesity impacts greatly on clinical outcomes and treatment responses to biologics in patients with ankylosing spondylitis, which argues strongly for obesity management to become central to prevention and treatment strategies in patients with AS.References:[1]Maachi M, Pieroni L, Bruckert E, et al.

The Impact

Background. We previously showed that grading can prognosticate the outcome of retroperitoneal liposarcoma (LPS). In the present study, we aimed to explore the impact of pathological stratification using grading on the clinical outcomes of patients with advanced well-differentiated LPS (WDLPS) and dedifferentiated LPS (DDLPS) treated with trabectedin. Patients: We included patients with advanced WDLPS and DDLPS treated with trabectedin at the Fondazione IRCCS Istituto Nazionale dei Tumori between April 2003 and November 2019. Tumors were categorized in WDLPS, low-grade DDLPS, and high-grade DDLPS according to the 2020 WHO classification. Patients were divided in two cohorts: Low-grade (WDLPS/low-grade DDLPS) and high-grade (high-grade DDLPS). Results: A total of 49 patients were included: 17 (35%) in the low-grade cohort and 32 (65%) in the high-grade cohort. Response rate was 47% in the low-grade cohort versus 9.4% in the high-grade cohort (logistic regression p = 0.006). Median progression-free survival (PFS) was 13.7 months in the low-grade cohort and 3.2 months in the high-grade cohort. Grading was confirmed as an independent predictor of PFS in the Cox proportional-hazards regression multivariable model (adjusted hazard ratio low-grade vs. high-grade: 0.45, 95% confidence interval: 0.22–0.94; adjusted p = 0.035). Conclusions: In this retrospective case series, sensitivity to trabectedin was higher in WDLPS/low-grade DDLPS than in high-grade DDLPS. If confirmed in larger series, grading could represent an effective tool to personalize the treatment with trabectedin in patients with advanced LPS.

Introduction: Uterine sarcoma accounts for nearly 3% of all uterine malignancies. They have 4 major pathology includes endometrial stromal sarcoma high grade, ESS low grade, uterine leiomyosarcoma (uLMS) and undifferentiated uterine sarcoma (UUS). Recent WHO classification 2014, recognizes low grade ESS and high grade ESS as distinct entity. They differ from endometrial carcinoma in their aggressive nature and poor prognosis. We review our database and found total 44 eligible patient treated at our institute. Materials and Methods: Its retrospective analysis of computer based database of our institute from January 2009 to December 2015. We analyzed demographic, pathological, treatment and survival data. Results: Total 44 patient treated for uterine sarcoma at our institute. Among these 16 were operated at our institute during study period. Here we reporting results of operated patients at our institute. The histological diagnosis LMS (5/16), ESS-L (4/16), MMMT (3/16), UUS (3/16) and ESS-H (1/16). Stage distribution was stage I, (6/16) stage II, (5/16) stage III, (3/16) stage IV, (0/16) and unknown stage (2/16). Two patients underwent completion surgery for outside myomectomy. The adjuvant treatment was CT in 3/16, CT with RT in 7/16, HT in 4/16 and one lost to follow up with one was put on observation. Median follow up is 30 month with 14 patients alive and one lost to follow up. At last follow up 4 patients alive with metastatic disease and 10 patients alive with no evidence of disease. Conclusion: Uterine sarcoma are uncommon disease with

Background: The Paris System for Reporting Urinary Cytology represents a significant improvement in classification of urinary specimens. The system acknowledges the difficulty in cytologically diagnosing low-grade urothelial carcinomas and has developed categories to deal with this issue. The system uses six categories: unsatisfactory, negative for high-grade urothelial carcinoma (NHGUC), atypical urothelial cells, suspicious for high-grade urothelial carcinoma, high-grade urothelial carcinoma, other malignancies and a seventh subcategory (low-grade urothelial neoplasm). Methods: Three hundred and fifty-seven urine specimens were independently reviewed by four cytopathologists unaware of the previous diagnoses. Each cytopathologist rendered a diagnosis according to the Paris System categories. Agreement was assessed using absolute agreement and weighted chance-corrected agreement (kappa). Disagreements were classified as low impact and high impact based on the potential impact of a misclassification on clinical management. Results: The average absolute agreement was 65% with an average expected agreement of 44%. The average chance-corrected agreement (kappa) was 0.32. Nine hundred and ninety-nine of 1902 comparisons between rater pairs were in agreement, but 12% of comparisons differed by two or more categories for the category NHGUC. Approximately 15% of the disagreements were classified as high clinical impact. Conclusions: Our findings indicated that the scheme recommended by the Paris System shows adequate precision for the category NHGUC, but the other categories demonstrated unacceptable interobserver variability. This low level of diagnostic precision may negatively impact the applicability of the Paris System for widespread clinical application.

Objective and design A clinicopathological score has been proposed by Trouillas et al. to predict the evolution of pituitary adenomas. Aim of our study was to perform an independent external validation of this score and identify other potential predictor of post-surgical outcome. Methods The study sample included 566 patients with pituitary adenomas, specifically 253 FSH/LH-secreting, 147 GH-secreting, 85 PRL-secreting, 72 ACTH-secreting and 9 TSH-secreting tumours with at least 3-year post-surgical follow-up. Results In 437 cases, pituitary adenomas were non-invasive, with low (grade 1a: 378 cases) or high (grade 1b: 59 cases) proliferative activity. In 129 cases, tumours were invasive, with low (grade 2a: 87 cases) or high (grade 2b: 42 cases) proliferative activity. During the follow-up (mean: 5.8 years), 60 patients developed disease recurrence or progression, with a total of 130 patients with pituitary disease at last follow-up. Univariate analysis demonstrated a significantly higher risk of disease persistence and recurrence/progression in patients with PRL-, ACTH- and FSH/LH-secreting tumours as compared to those with somatotroph tumours, and in those with high proliferative activity (grade 1b and 2b) or >1 cm diameter. Multivariate analysis confirmed tumour type and grade to be independent predictors of disease-free-survival. Tumour invasion, Ki-67 and tumour type were the only independent prognostic factors of disease-free survival. Conclusions Our data confirmed the validity of Trouillas’ score, being tumour type and grade independent predictors of disease evolution. Therefore, we recommend to always consider both features, together with tumour histological subtype, in the clinical setting to early identify patients at higher risk of recurrence.

Background: Endoscopic ultrasonography (EUS) is an important tool for diagnosis and pretreatment staging of primary gastric lymphoma. The aim of the study was to evaluate the diagnostic importance of endosonography (EUS)in gastric lymphoma; to assess the depth of tumoral infiltration in low-grade gastric lymphoma of mucosa-associated lymphoid tissue (MALT) and to assess EUS response to medical treatment (Cyclophosphamid/Mabtera and/or anti-Helicobacter pylori therapy). Methods: 26 patients with MALT gastric lymphoma were investigated by EUS. Six of them were evaluated after the eradication of Helicobacter pylori infection and 20 after and during the cyclophosphamide/Mabtera and anti H.pylori treatment. EUS staging was compared with histopathology. Tumors were staged according to the 2000 TNM and modified Ann Arbor classification. Results: Six patients were treated with anti - Helicobacter pylori eradication therapy. Full regression of lymphoma was observed in 2 of 6 (33.3%) patients, which was endoscopicaly and histologicaly proved. EUS correlated with histology in all (6/6). In 20 patients treated with cyclophosphamide/Mabtera therapy, EUS revealed regression of lymphoma in 14 cases. Positive correlation with histology was found in 11 patients (11/14; 78%). The initial EUS showed an increased wall thickness more than 5mm in 24 of 26 patients (92%). The thickening was predominantly of mucosa and submucosa and in 11 patients extended the muscularis propria. After the therapy, the gastric wall thickening returned to normal in 14 patients, however, 3 of them still had positive histology findings. In 2 cases, during the follow-up, the EUS showed remained thickening of gastric wall, whereas biopsies were negative. Six months later histology revealed progressive low-grade MALT lymphoma in this cases. Conclusion: EUS appears to be a sensitive procedure for initial staging and assessment of treatment response and long-term follow up in patients with gastric lymphoma. The importance of EUS lies in ability to detect relapse early, too.
