Abstract
But : Les tumeurs urothéliales de la vessie sont rares chez le jeune adulte. Leur profil évolutif et leur pronostic restent matière à controverse. Nous rapportons notre expérience à propos de 54 patients.Méthodologie : Entre 1990 et 2010, 54 patients de moins de 40 ans au moment du diagnostic ont été traités pour carcinome à cellules transitionnelles de la vessie. Nous avons étudié le profil évolutif de ces tumeurs en séparant les patients en deux groupes (moins de 30 ans, et 30 à 40 ans). Résultats : La tumeur n’infiltrait pas le muscle vésical dans 37 cas et l’infiltrait dans 17 cas. Pour les tumeurs n’infiltrant pas le muscle vésical, elles étaient de stade Ta dans 20 cas et de grade I-II dans 36 cas. Le pronostic de ces tumeurs était meilleur avant l’âge de 30 ans avec un taux de récidive de 15,3 % sans progression. Pour les patients de 30 à 40 ans, le taux de récidive était de 33,3 %, et 25 % des tumeurs qui ont récidivé ont présenté une progression du stade. Pour les tumeurs infiltrant le muscle vésical, le pronostic était sombre (localement avancées dans neuf cas et métastatiques d’emblée dans cinq cas).Conclusion : Le profil évolutif des tumeurs n’infiltrant pas le muscle vésical a semblé meilleur avant l’âge de 30 ans. Entre 30 et 40 ans, le profil évolutif s’est approché de celui des sujets âgés. Les tumeursinfiltrantes étaient souvent évoluées et agressives, évoquant un potentiel évolutif particulier.

The potential effect of age on the natural behavior of bladder cancer: Does urothelial cell carcinoma progress differently in various age groups? Kaohsiung J Med Sci 2016; 32:261-6. [PMID: 27316585 DOI: 10.1016/j.kjms.2016.03.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2015] [Revised: 01/22/2016] [Accepted: 03/01/2016] [Indexed: 01/01/2023] Open
Abstract
We aimed to evaluate the potential effect of age on the natural behavior of bladder cancer and to compare these findings between different age groups. The clinical and pathologic data of 239 patients treated at our institution between 1994 and 2014 were analyzed. The patients were classified into three groups according to age: ≤ 40 years (Group 1), 41-59 years (Group 2), and ≥ 60 years (Group 3). The following data were collected: characteristics of the patients, initial pathological findings after transurethral resection, tumor stage and grade, tumor size and multiplicity, and disease recurrence and progression. The mean age of the patients at initial diagnosis was 34.2±5.5 years, 53±5.1 years, and 71.1±7 years in Groups 1, 2, and 3, respectively. There were 207 (86.6%) patients with nonmuscle-invasive urothelial bladder cancer and 32 (13.4%) patients with muscle-invasive disease. Tumor recurrence was significantly lower in Group 1 than in Group 2 (p=0.001) and Group 3 (p=0.001). Although the time to tumor recurrence was significantly different between the three groups (p=0.001), no significant difference was noted in the time to progression (p=0.349). Patients with urothelial cancer younger than 40 years tend to have single and small tumors. The tumor recurrence rate is lower in the younger age group, but tumor progression is similar in older and younger patients. Therefore, the findings indicate that clinicians should be careful when assessing the invasiveness of urothelial tumors in younger patients and start treatment as soon as possible.

Abstract
INTRODUCTION The aim of the study is to reveal pathologic characteristics and clinical behaviour of patients 40 years old or younger diagnosed with and treated for urothelial bladder carcinoma. METHODS We retrospectively analyzed the clinical and pathologic data of 91 patients, initially diagnosed and treated at our institution from May 1996 to December 2014. Cancer recurrence was defined as new occurrence of bladder cancer at the same or different sites of the bladder. Cancer progression was defined as an increase in stage or grade in any of the recurrences. RESULTS The mean age was 33.8 (range: 17-40) years. The pathological examination after transurethral resection revealed 83 (91.2%) patients with non-muscle invasive urothelial bladder cancer, and 8 (8.8%) patients with muscle invasive urothelial bladder cancer. According to the distribution of grade, there were 75, 4 and 12 patients with grade 1, grade 2 and grade 3 diseases, respectively. Initial cancer staging was: pTa with 40 patients (43.9%), pT1 with 43 patients (47.2%), pT2 with 7 patients (7.6%), and pT3 with 1 patient (1.2%). While 17 (18.6%) patients recurred in the follow-up, 10 (10.9%) patients had progression. There were no differences in recurrence and progression rates in the Ta and T1 stages between groups (p = 0.233, p = 0.511, respectively). CONCLUSION The risk of progression increased as the number of relapses increased. The clinical behaviour of high-stage and high-grade disease in younger patients is similar to the older group.

Abstract
INTRODUCTION Bladder cancers are not very common in the young population below 20 years of age, especially in those who have not been exposed to chemotherapy, bladder augmentation surgery and other known risk factors. By highlighting this case we hope to raise awareness in the medical community, that the symptom of visible haematuria can potentially be due to a bladder malignancy and therefore this should be thoroughly investigated. PRESENTATION OF CASE An 18-year-old female presented with intermittent macroscopic haematuria and non-specific abdominal pain. Physical examination and routine blood tests were normal. An ultrasound scan initially showed a bladder wall lesion, which a flexible cystoscopy confirmed. Histology revealed grade 2 papillary transitional cell carcinoma of the bladder with no invasion into the lamina propria (G2pTa TCCB). DISCUSSION We recognise through our literature review that paediatric bladder cancers are not commonly reported in the UK. In our paper we highlight the relevant major studies that have been carried out world-wide, the reported incidence so far and gaps in the evidence base. CONCLUSION Despite the dearth of data about paediatric bladder malignancies there is enough case-based evidence, from world-wide sources, to support that bladder cancer must be suspected in the event of macroscopic haematuria. Ultrasound and cystoscopy are the standard diagnostic tools for bladder tumours. Endoscopic resection of the tumour followed up by interval ultrasound scans and flexible cystoscopy checks remain the mainstay of treatment hitherto.

Abstract
Bladder urothelial carcinoma is rare in young adults and occurs more commonly in older individuals. The aim of this study was to compare the clinical behavior, pathologic characteristics, and prognosis of urothelial carcinoma of urinary bladder in young versus older adults. A retrospective review of our records between 2007 and 2013 identified 56 patients (42 males and 14 females) with transitional cell carcinoma of the bladder who were less than 40 years old. Clinical and pathological parameters of patients who were less than 40 years of age were compared with those of a series of patients older than 40 years of age (the control group) during the same period. A survival analysis was performed using the Kaplan-Meier method and log-rank test, and Cox regression was performed to identify clinical parameters that affected the clinical outcomes. The mean age was 29.21 years (range, 5-40 years) for patients less than 40 years old and 61.66 years (range, 41-75) for those older than 40 years. The mean follow-up was 40.26 months (range, 12-65 months) for young patients and 42.57 months (range, 12-72 months) for the older patients. Young bladder cancer patients had smaller-sized tumors (less than 3 cm), less high-grade cancers, higher papillary urothelial neoplasms of low malignant potential, and low-grade tumors than patients older than 40 years. Multivariate logistic regression analysis predicted tumor recurrence in young patients with high-grade tumors [odds ratio (OR), 1.959; 95% confidence interval (CI), 1.235-2.965; p = 0.046] and tumors larger than 3 cm (OR, 1.772; 95% CI, 1.416-1.942; p = 0.032). The 5-year overall survival rate was 100% for young patients and 88.1% for older patients. No difference was observed in the recurrence-free (p = 0.321) and progression-free (p = 0.422) survival rates between the two groups. We concluded that although the clinical stage distribution, natural history, and outcomes of bladder urothelial cancer in young adults are similar to those in their older counterparts, clinicians must be aware that patients under 40 years of age presented with higher-grade and larger (>3 cm) tumors and are more likely to experience tumor recurrence.

Abstract
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.

Abstract
INTRODUCTION AND AIM Urothelial bladder carcinoma (UBC) is a very rare condition in patients aged below 50 years. The aim of the study was to answer the question whether the characteristics of cancer in this group of patients differ from general UBC features. MATERIAL AND METHODS Altogether 2160 patients treated with primary transurethral resection due to a bladder tumor were included in the study. The mean age of the cohort was 69.1 years (range 11-100). Patients were divided into three subgroups depending on age: age <41 years (group 1), age 41-50 years (group 2), age >50 years (group 3). Sex ratio, tumor grade, and stage of disease were recorded. RESULTS Women constituted 18.5%, 19.2%, and 25.8% of the patients in groups 1, 2, and 3, respectively (P < 0.05). WHO grade 3 tumors were diagnosed in 0%, 8.5%, and 17.2%, respectively (P < 0.05). Non-invasive papillary carcinoma was found in 100.0%, 76.7%, and 62.7%, respectively (P < 0.05). The incidence of muscle-invasive bladder cancer was 0%, 11.0%, and 15.6%, respectively (P < 0.05). CONCLUSIONS Pathological characteristics of UBC are dependent on the patients' age. Being a very rare condition, UBC in young patients is characterized by a relatively good prognosis.

Abstract
Introduction. There is not much evidence regarding clinical behavior of bladder cancer in younger patients. We evaluated clinical characteristics, tumor recurrence and progression in patients younger than 40 years old with urothelial bladder carcinoma. Methods. We retrospectively reviewed the medical records of 31 patients less than 40 years old who were firstly managed with bladder urothelial carcinoma in our department. Data were analysed with the Chi-square test. Results. Mean age was 31.7 years. Mean followup was 38.52 months (11–72 months). Nineteen (61%) patients were diagnosed with GII and 2 (6%) patients with GIII disease. Five (16%) patients presented with T1 disease. Three (9%) patients with invasive disease underwent cystectomy and adjuvant chemotherapy and one developed metastatic disease. Ten (32%) patients recurred during followup with a disease free recurrence rate of 65% the first 2 years after surgery. From those, 1 patient progressed to higher stage and three to higher grade disease. No patient died during followup. Conclusions. Bladder urothelial carcinoma in patients younger than 40 years is usually low stage and low grade. Management of these patients should be according to clinical characteristics and no different from older patients with the same disease.

Abstract
Bladder urothelial carcinoma is typically a disease of older individuals and rarely occurs below the age of 40 years. There is debate and uncertainty in the literature regarding the clinicopathologic characteristics of bladder urothelial neoplasms in younger patients compared with older patients, although no consistent age criteria have been used to define "younger" age group categories. Use of the World Health Organization 2004/International Society of Urological Pathology 1998 grading nomenclature and recent molecular studies highlight certain unique features of bladder urothelial neoplasms in young patients, particularly in patients below 20 years of age. In this meta-analysis and review, the clinical, pathologic, and molecular features and risk factors of bladder urothelial neoplasms in patients 40 years or less are presented and analyzed according to decades of presentation. Similar to older patients, bladder urothelial neoplasms in patients 40 years or younger occur more common in male patients, present mainly with gross painless hematuria, and are more commonly located at bladder trigone/ureteral orifices, but in contrast have a greater chance for unifocality. Delay in diagnosis of bladder urothelial neoplasms seems not to be uncommon in younger patients probably because of its relative rarity and the predominance of benign causes of hematuria in this age group causing hesitancy for an aggressive work-up. Most tumors in patients younger than 40 years were low grade. The incidence of low-grade tumors was the lowest in the first 2 decades of life, with incremental increase of the percentage of high-grade tumors with increasing age decades. Classification according to the World Health Organization 2004/International Society of Urological Pathology grading system identified papillary urothelial neoplasms of low malignant potential to be relatively frequent among bladder tumors of young patients particularly in the teenage years. Similar to grade, there was marked predominance of low stage tumors in the first 2 decades of life with gradual inclusion of few higher stage and metastatic tumors in the 2 older decades. Bladder urothelial neoplasms occurring in patients <20 years of age lack or have a much lower incidence of aberrations in chromosome 9, FGFR3, p53, and microsatellite instability and have fewer epigenetic alterations. Tumor recurrence and deaths were infrequent in the first 2 decades and increased gradually in each successive decade, likely influenced by the increased proportion of higher grade and higher stage tumors. Our review of the literature shows that urothelial neoplasms of the bladder occurring in young patients exhibit unique pathologic and molecular features that translate to its more indolent behavior; this distinction is most pronounced in patients <20 years. Our overall inferences have potential implications for choosing appropriate noninvasive diagnostic and surveillance modalities, whenever feasible, and for selecting suitable treatment strategies that factor in quality of life issues vital to younger patients.

Abstract
Background The molecular characteristics and the clinical disease course of bladder cancer (BC) in young patients remain largely unresolved. All patients are monitored according to an intensive surveillance protocol and we aim to gain more insight into the molecular pathways of bladder tumors in young patients that could ultimately contribute to patient stratification, improve patient quality of life and reduce associated costs. We also determined whether a biomarker-based surveillance could be feasible. Case Presentation We report a unique case of a 26-year-old Caucasian male with recurrent non-muscle invasive bladder tumors occurring at a high frequency and analyzed multiple tumors (maximal pTaG2) and urine samples of this patient. Analysis included FGFR3 mutation detection, FGFR3 and TP53 immunohistochemistry, mircosatellite analysis of markers on chromosomes 8, 9, 10, 11 and 17 and a genome wide single nucleotide polymorphism-array (SNP). All analyzed tumors contained a mutation in FGFR3 and were associated with FGFR3 overexpression. None of the tumors showed overexpression of TP53. We found a deletion on chromosome 9 in the primary tumor and this was confirmed by the SNP-array that showed regions of loss on chromosome 9. Detection of all recurrences was possible by urinary FGFR3 mutation analysis. Conclusions Our findings would suggest that the BC disease course is determined by not only a patient's age, but also by the molecular characteristics of a tumor. This young patient contained typical genetic changes found in tumors of older patients and implies a clinical disease course comparable to older patients. We demonstrate that FGFR3 mutation analysis on voided urine is a simple non-invasive method and could serve as a feasible follow-up approach for this young patient presenting with an FGFR3 mutant tumor.

Abstract
BACKGROUND The clinical behavior and prognosis of bladder cancer in young patients is not well defined. The aim of this study was, therefore, to evaluate the clinical behavior, pathologic characteristics and prognosis of urothelial carcinoma of the urinary bladder in young adults. METHODS We retrospectively reviewed records from 30 young patients (23 males, 7 females; age < or = 40 years) with urothelial carcinoma of the urinary bladder who had been treated in our hospital between May 1990 and October 2003. Data were analyzed by the Kaplan-Meier method to assess disease recurrence and survival. RESULTS The mean age at diagnosis was 34.3 +/- 5 years (range, 22-40 years). Fifteen patients presented with pTa, 9 with pT1, 4 with pT2, 1 with pT3, and 1 with pT4. Twenty-six patients (87.2%) had low-grade bladder cancer, and the other 4 had high-grade disease. The most frequent initial presenting symptom was gross hematuria. The mean postoperative follow-up period was 72.8 months (range, 4-149 months). Fifty percent of superficial bladder cancers recurred a mean of 10.7 months (range, 3-68 months) after operation. One patient died from invasive bladder cancer after radical cystectomy, and 1 died from superficial bladder cancer due to tumor progression. The 5-year cancer-specific survival rate was 95.2% for superficial cancer and 83.3% for invasive cancer. The overall survival rate was 93.3%. CONCLUSION Urothelial carcinoma of the urinary bladder in young adults is usually associated with low grade and low stage. Invasive bladder cancer had no worse a survival rate than superficial bladder cancer.
