Mortality from prostate cancer in the years 2007-2021 in North Rhine-Westphalia, Germany. BMC Urol 2024; 24:181. [PMID: 39192311 DOI: 10.1186/s12894-024-01564-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2024] [Accepted: 08/12/2024] [Indexed: 08/29/2024] Open
Abstract
BACKGROUND The crude mortality rate and the lifetime mortality risk from prostate cancer in Germany are above international average. However age-standardised mortality and years of life lost per capita from prostate cancer are declining. This study analyses the mortality-related measures for the federal state of North Rhine-Westphalia (NRW) in Germany. METHODS Based on the cause of death statistics and data from the NRW State Cancer Registry on 45,300 deaths in the years 2007-2021, mortality rates, the lifetime mortality risk from prostate cancer, median age at death and years of life lost are presented. Additionally, the 15 most frequent causes of death of 95,013 patients diagnosed with prostate cancer are reported. RESULTS With a stable lifetime mortality risk from prostate cancer, age-standardised mortality and years of life lost per capita are decreasing while crude mortality and median age at death are increasing in NRW. Less than half of the patients die from their prostate cancer. Cancers of the urinary bladder and other urinary organs also occur more frequently as a cause of death than it would be expected based on the age-specific risk in the total population. CONCLUSIONS More people in North Rhine-Westphalia are dying of prostate cancer over time due to demographic ageing alone. At the same time, the age-specific mortality risk has not increased and when patients die of prostate cancer, it is at an increasingly older age. However, there is a statistical association with deaths from cancers of the lower urinary tract in patients diagnosed with prostate cancer, which demands further evaluation.

Abstract
The prevalence of double primary prostate and bladder cancer is not uncommon. Though both share a common pathway of malignant transformation, they bear to differ in the case of 2-[18F]FDG PET/CT and [68Ga]Ga-PSMA uptake. We present a case of double primary cancer involving the bladder and prostate, where the prostatic primary showed intense [68Ga]Ga-PSMA uptake with non-avid skeletal and pulmonary metastases, which showed intense 2-[18F]FDG uptake, thus showing discordance due to different clonal origins.

Abstract
Prostate cancer remains a significant public health concern in sub-Saharan Africa, particularly impacting South Africa with high mortality rates. Despite many years of extensive research and significant financial expenditure, there has yet to be a definitive solution to prostate cancer. It is not just individuals who vary in their response to treatment, but even different nodules within the same tumor exhibit unique transcriptome patterns. These distinctions extend beyond mere differences in gene expression levels to encompass the control and networking of individual genes. Escalating chemotherapy resistance in prostate cancer patients has prompted increased research into its underlying mechanisms. The heterogeneous nature of transcriptomic organization among men makes the pursuit of universal biomarkers and one-size-fits-all treatments impractical. This study delves into the expression of drug resistance-associated genes, ABCB1 and CYP1B1, in cancer cells. Employing bioinformatics, we explored the molecular pathways and cascades linked to drug resistance following upregulation of these genes. Samples were obtained from archived prostate cancer patient specimens through pre-treatment biopsies of two categories: good vs. poor responders, with cDNAs synthesized from isolated RNAs subjected to qPCR analysis. The results revealed increased ABCB1 and CYP1B1 expression in tumor samples of the poor responders. Gene enrichment and network analysis associated ABCB1 with ABC transporters and LncRNA-mediated therapeutic resistance (WP3672), while CYP1B1 was linked to ovarian steroidogenesis, tryptophan metabolism, steroid hormone biosynthesis, benzo(a)pyrene metabolism, the sulindac metabolic pathway, and the estrogen receptor pathway, which are associated with drug resistance. Both ABCB1 and CYP1B1 correlated with microRNAs in cancer and the Nuclear Receptors Meta-Pathway. STRING analysis predicted protein-protein interactions of ABCB1 and CYP1B1 with Glutathione S-transferase Pi, Catechol O-methyltransferase, UDP-glucuronosyltransferase 1-6, Leucine-rich Transmembrane and O-methyltransferase (LRTOMT), and Epoxide hydrolase 1, with scores of 0.973, 0.971, 0.966, 0.966, and 0.966, respectively. Furthermore, molecular docking analysis of the chemotherapy drug, docetaxel, with CYP1B1 and ABCB1 revealed robust molecular interactions, with binding energies of -20.37 and -15.25 Kcal/mol, respectively. These findings underscore the susceptibility of cancer patients to drug resistance due to increased ABCB1 and CYP1B1 expression in tumor samples from patients in the poor-responders category that affects associated molecular pathways. The potent molecular interactions of ABCB1 and CYP1B1 with docetaxel further emphasize the potential basis for chemotherapy resistance.

Abstract
Bladder urothelial carcinoma (BLCA) is the 10th most common cancer with a low survival rate and strong male bias. We studied the field cancerization in BLCA using multi-sample- and multi-tissue-per-patient protocol for sensitive detection of autosomal post-zygotic chromosomal alterations and loss of chromosome Y (LOY). We analysed 277 samples of histologically normal urothelium, 145 tumors and 63 blood samples from 52 males and 15 females, using the in-house adapted Mosaic Chromosomal Alterations (MoChA) pipeline. This approach allows identification of the early aberrations in urothelium from BLCA patients. Overall, 45% of patients exhibited at least one alteration in at least one normal urothelium sample. Recurrence analysis resulted in 16 hotspots composed of either gains and copy number neutral loss of heterozygosity (CN-LOH) or deletions and CN-LOH, encompassing well-known and new BLCA cancer driver genes. Conservative assessment of LOY showed 29%, 27% and 18% of LOY-cells in tumors, blood and normal urothelium, respectively. We provide a proof of principle that our approach can characterize the earliest alterations preconditioning normal urothelium to BLCA development. Frequent LOY in blood and urothelium-derived tissues suggest its involvement in BLCA.

Abstract
BACKGROUND Many survivors of a first primary cancer (FPCs) are at risk of developing a second primary cancer (SPC), with effects on patient prognosis. Primary cancers have different frequencies of specific SPC development and the development of SPCs may be closely related to the FPC. The aim of this study was to explore possible correlations between SPCs and FPCs. METHODS Relevant literature on SPCs was retrospectively searched and screened from four databases, namely, PubMed, EMBASE, Web of Science, and PMC. Data on the number of patients with SPC in 28 different organ sites were also collected from The Surveillance, Epidemiology, and End Results (SEER) 8 Registry and NHANES database. RESULTS A total of 9 617 643 patients with an FPC and 677 430 patients with an SPC were included in the meta-analysis. Patients with a first primary gynaecological cancer and thyroid cancer frequently developed a second primary breast cancer and colorectal cancer. Moreover, those with a first primary head and neck cancer, anal cancer and oesophageal cancer developed a second primary lung cancer more frequently. A second primary lung cancer and prostate cancer was also common among patients with first primary bladder cancer and penile cancer. Patients with second primary bladder cancer accounted for 56% of first primary ureteral cancer patients with SPCs. CONCLUSIONS This study recommends close clinical follow-up, monitoring and appropriate interventions in patients with relevant FPCs for better screening and early diagnosis of SPCs.

Abstract
BACKGROUND AND AIMS Second primary prostate cancer (SPPCa) is a common type of secondary malignancy that negatively impacts patient prognosis. This study aimed to identify prognostic factors for SPPCa patients and develop nomograms to assess their prognosis. METHODS Patients diagnosed with SPPCa between 2010 and 2015 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. The study cohort was randomly divided into a training set and a validation set. Cox regression analysis, Kaplan‒Meier survival analysis, and least absolute shrinkage and selection operator regression analysis were used to identify independent prognostic factors and develop the nomogram. The nomograms were evaluated using the concordance index (C-index), calibration curve, area under the curve (AUC), and Kaplan-Meier analysis. RESULTS A total of 5342 SPPCa patients were included in the study. Independent prognostic factors for overall survival (OS) and cancer-specific survival (CSS) were identified as age, interval between diagnoses, first primary tumor site, and AJCC stage, N stage, M stage, PSA, Gleason score, and SPPCa surgery. Nomograms were constructed based on these prognostic factors, and the performance was evaluated using the C-index (OS: 0.733, CSS: 0.838), AUC, calibration curve, and Kaplan-Meier analysis, which demonstrated excellent predictive accuracy. CONCLUSION We successfully established and validated nomograms to predict OS and CSS in SPPCa patients using the SEER database. These nomograms provide an effective tool for risk stratification and prognosis assessment in SPPCa patients, which will aid clinicians in optimizing treatment strategies for this patient population.

Abstract
BACKGROUND To explore correlations between the clinical attributes of secondary bladder cancer and brachytherapy, we retrospectively reviewed our institutional database on patients with localized prostate cancer who underwent low-dose-rate brachytherapy (LDR-BT) or high-dose-rate brachytherapy (HDR-BT) with or without external beam radiation therapy (EBRT) or radical prostatectomy (RP). METHODS From October 2003 to December 2014, 2551 patients with localized prostate cancer were treated at our institution. Of these, data on 2163 were available (LDR-BT alone: n = 953; LDR-TB with EBRT: n = 181; HDR-BT with EBRT: n = 283; RP without EBRT: n = 746). The times of secondary bladder cancer development subsequent to radical treatment, and their clinical characteristics, were studied. RESULTS Age-adjusted Cox's regression analyses indicated that brachytherapy did not significantly impact the incidence of secondary bladder cancer. However, the pathological characteristics of such cancer differed between patients treated via brachytherapy and RP without EBRT; invasive bladder cancer was more common in such patients. CONCLUSION The risk for secondary bladder cancer was not significantly increased after brachytherapy compared to non-irradiation therapy. However, brachytherapy patients exhibited a higher incidence of invasive bladder cancer. Therefore, meticulous follow-up is crucial for early detection and treatment of bladder cancer in such patients.

Abstract
Among the multiple primary malignant tumors, breast cancer is the most common and in most cases it is combined with the second mammary gland, uterine body, stomach, colon, skin and ovary. Breast angiosarcoma is a very rare disease with unfavorable prognosis. Radiation therapy to the area of the breast is considered to be the main risk factor for the radiation-induced angiosarcoma. Diagnosis is based on the clinical aspect, the results of morphological and immunohistochemical findings. There are no uniform standards for the treatment of this pathology; a surgical method, systemic therapy, and radiation therapy are used. The article presents a clinical case of a female patient born in 1952, who was diagnosed with synchronous multiple primary cancer in 2014: stage 2A left breast cancer (cT2N0M0); bladder cancer stage I (cT1cN0M0). After the complex treatment, the patient received adjuvant endocrine therapy with Tamoxifen. In December 2018, single bluish formations appeared in the area of the postoperative scar, followed by a rapid growth of formations on the skin within a month, with a tendency to merge and necrosis. The patient was sent for biopsy of the formations with suspected recurrence of the disease. Immunomorphological patterns correspond to the angiosarcoma in the skin of the mammary gland. A simple mastectomy was performed. After 3 months, growth of angiomyosarcoma in the soft tissues of the anterior chest wall continued. Excision of the tumor in the soft tissues of the chest was performed and the patient underwent postoperative course of radiation therapy with a single focal dose (SFD) 2.5 Gy, total boost isodose of 50 Gy. At follow-up examinations held from January to December 2021, there is no evidence for continued growth and recurrence of the disease. The presented clinical observation demonstrates the experience of diagnostics and treatment of radiation-induced angiosarcoma in the patient with multiple primary synchronous lesions of the breast and bladder.

Abstract
Prostate cancer is one of the malignancies that affects men and significantly contributes to increased mortality rates in men globally. Patients affected with prostate cancer present with either a localized or advanced disease. In this review, we aim to provide a holistic overview of prostate cancer, including the diagnosis of the disease, mutations leading to the onset and progression of the disease, and treatment options. Prostate cancer diagnoses include a digital rectal examination, prostate-specific antigen analysis, and prostate biopsies. Mutations in certain genes are linked to the onset, progression, and metastasis of the cancer. Treatment for localized prostate cancer encompasses active surveillance, ablative radiotherapy, and radical prostatectomy. Men who relapse or present metastatic prostate cancer receive androgen deprivation therapy (ADT), salvage radiotherapy, and chemotherapy. Currently, available treatment options are more effective when used as combination therapy; however, despite available treatment options, prostate cancer remains to be incurable. There has been ongoing research on finding and identifying other treatment approaches such as the use of traditional medicine, the application of nanotechnologies, and gene therapy to combat prostate cancer, drug resistance, as well as to reduce the adverse effects that come with current treatment options. In this article, we summarize the genes involved in prostate cancer, available treatment options, and current research on alternative treatment options.

[PMID: 35392296 PMCID: PMC8980432 DOI: 10.1177/11769351221087046] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Accepted: 02/22/2022] [Indexed: 12/30/2022] Open
Abstract
The prevalence of TP53 mutations in advanced prostate cancers (PCa) is 3 to 5 times of the quantity in primary PCa. By an integrative analysis of the Cancer Genome Atlas and Catalogue of Somatic Mutations in Cancer data, we revealed the supporting evidence for 2 complementary hypotheses: H1 - TP53 abnormalities promote metastasis or therapy-resistance of PCa cells, and H2—part of TP53 mutations in PCa metastases occur after the diagnosis of original cancers. The plausibility of these hypotheses can explain the increased prevalence of TP53 mutations in PCa metastases. With H1 and H2 as the general assumptions, we developed mathematical models to decipher the change of the percentage frequency (prevalence) of TP53 mutations from primary tumors to metastases. The following results were obtained. Compared to TP53-normal patients, TP53-mutated patients had poorer biochemical relapse-free survival, higher Gleason scores, and more advanced t-stages (P < .01). Single-nucleotide variants in metastases more frequently occurred on G bases of the coding sequence than those in primary cancers (P = .03). The profile of TP53 hotspot mutations was significantly different between primary and metastatic PCa as demonstrated in a set of statistical tests (P < .05). By the derived formulae, we estimated that about 40% TP53 mutation records collected from metastases occurred after the diagnosis of the original cancers. Our study provided significant insight into PCa progression. The proposed models can also be applied to decipher the prevalence of mutations on TP53 (or other driver genes) in other cancer types.

Abstract
OBJECTIVE This study aims to analyze the challenges, approaches and long-term results of primary or metachronous prostate cancer (PCa) in cases with multiple primary genitourinary cancers. METHODOLOGY A total of 17 patients were included in the study. Patients with multiple primary genitourinary cancers were divided into two groups according to the diagnosis of primary or metachronous PCa as group 1 and group 2. RESULTS The median age of patients was similar in both groups. The median smoking status (pack-years) was higher in group 2 than group 1. The median prostate-specific antigen (PSA) level was higher in group 1 than group 2. The median follow-up time from primary to the metachronous tumour was higher in group 1 than group 2. The rate of recurrence in PCa was higher in group 1 than group 2. No statistically significant difference was observed in terms of patients' age, smoking status, PSA levels at diagnosis of PCa and biochemical recurrence or metastasis between the two groups (p > 0.05). CONCLUSION Primary PCa cases may progress more aggressively than metachronous PCa cases. Biochemical recurrence and metastasis may be less threatening in metachronous PCa cases than primary cases. Therefore, aggressive treatment can be avoided for metachronous PCa cases.

Abstract
Abstract
Background
Bladder cancer (BCa) and prostate cancer (PCa) are frequent urothelial and genital malignancies with a high ratio of morbidity and mortality which are more common among males. Since BCa and PCa cases are mainly diagnosed in advanced stages with clinical complications, it is required to introduce the efficient early detection markers. Protein kinases are critical factors involved in various cellular processes such as cell growth, motility, differentiation, and metabolism. Deregulation of protein kinases can be frequently observed through the neoplastic transformation and tumor progression. Therefore, kinases are required to be regulated via different genetic and epigenetic processes. MicroRNAs (miRNAs) are among the critical factors involved in epigenetic regulation of protein kinases. Since miRNAs are noninvasive and more stable factors in serum and tissues compared with mRNAs, they can be used as efficient diagnostic markers for the early detection of PCa and BCa.
Main body
In present review, we have summarized all of the reported miRNAs that have been associated with regulation of protein kinases in bladder and prostate cancers.
Conclusions
For the first time, this review highlights the miRNAs as critical factors in regulation of protein kinases during prostate and bladder cancers which paves the way of introducing a noninvasive kinase-specific panel of miRNAs for the early detection of these malignancies. It was observed that the class VIII receptors of tyrosine kinases and non-receptor tyrosine kinases were the most frequent targets for the miRNAs in bladder and prostate cancers, respectively.

Abstract
Prostate adenocarcinoma, with its rising numbers and high fatality rate, is a daunting healthcare challenge to clinicians and researchers alike. The mainstay of our meta-analysis was to decipher differentially expressed genes (DEGs), their corresponding transcription factors (TFs), miRNAs (microRNA) and interacting pathways underlying the progression of prostate cancer (PCa). We have chosen multiple datasets from primary, castration-resistant, chemo-resistant and metastatic prostate cancer stages for investigation. From our tissue-specific and disease-specific co-expression networks, fifteen hub genes such as ACTB, ACTN1, CDH1, CDKN1A, DDX21, ELF3, FLNA, FLNC, IKZF1, ILK, KRT13, KRT18, KRT19, SVIL and TRIM29 were identified and validated by molecular complex detection analysis as well as survival analysis. In our attempt to highlight hub gene-associated mutations and drug interactions, FLNC was found to be most commonly mutated and CDKN1A gene was found to have highest druggability. Moreover, from DAVID and gene set enrichment analysis, the focal adhesion and oestrogen signalling pathways were found enriched which indicates the involvement of hub genes in tumour invasiveness and metastasis. Finally by Enrichr tool and miRNet, we identified transcriptional factors SNAI2, TP63, CEBPB and KLF11 and microRNAs, namely hsa-mir-1-3p, hsa-mir-145-5p, hsa-mir-124-3p and hsa-mir-218-5p significantly controlling the hub gene expressions. In a nutshell, our report will help to gain a deeper insight into complex molecular intricacies and thereby unveil the probable biomarkers and therapeutic targets involved with PCa progression.

Abstract
MOTIVATION Incorporating the temporal dimension into multimorbidity studies has shown to be crucial for achieving a better understanding of the disease associations. Furthermore, due to the multifactorial nature of human disease, exploring disease associations from different perspectives can provide a holistic view to support the study of their aetiology. RESULTS In this work, a temporal systems-medicine approach is proposed for identifying time-dependent multimorbidity patterns from patient disease trajectories, by integrating data from electronic health records with genetic and phenotypic information. Specifically, the disease trajectories are clustered using an unsupervised algorithm based on dynamic time warping and three disease similarity metrics: clinical, genetic and phenotypic. An evaluation method is also presented for quantitatively assessing, in the different disease spaces, both the cluster homogeneity and the respective similarities between the associated diseases within individual trajectories. The latter can facilitate exploring the origin(s) in the identified disease patterns. The proposed integrative methodology can be applied to any longitudinal cohort and disease of interest. In this article, prostate cancer is selected as a use case of medical interest to demonstrate, for the first time, the identification of temporal disease multimorbidities in different disease spaces.

Incidental Prostate Cancer in Radical Cystoprostatectomy Specimens is Associated with Worse Overall Survival. Bladder Cancer 2021; 7:205-211. [PMID: 38994542 PMCID: PMC11181765 DOI: 10.3233/blc-200396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Accepted: 03/31/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND The impact of incidental prostate cancer (IPC) on oncological outcomes after radical cystoprostatectomy (RCP) specimens from patients with bladder cancer (BC) remains controversial. This relationship has not been well elucidated in Asian countries, where the incidence of prostate cancer has recently shown dramatic increases. OBJECTIVES This study retrospectively compared pathological features and oncological outcomes between BC patients with and without IPC in the RCP specimens. METHODS This study included 142 men who underwent RCP for BC. Men who were previously diagnosed with prostate cancer were excluded. Each prostate gland and seminal vesicle was processed as whole mounts and 4-mm close-step sectioning was performed. A single genitourinary pathologist diagnosed IPC. The pathological features and oncological outcomes such as overall survival (OS), bladder cancer-specific survival (BCSS), and progression-free survival (PFS) were compared between patients with IPC (IPC+group, n = 45) and without IPC (IPC- group, n = 97). P values less than 0.05 considered to indicate statistical significance for patients' characteristics. Because of multi-primary endpoint, P values less than 0.0167 was considered statistical significance for oncological outcomes. RESULTS We detected IPC in 45 RCP specimens (31.6%). Patients in the IPC- group were significantly younger at surgery than those in the IPC+group (P < 0.001). The pathological features of the RCP specimens did not differ significantly. In multivariable analyses, presence of IPC was significantly associated with worse OS (P = 0.005), but not with either BCSS or PFS (P = 0.038 and 0.326, respectively). In Kaplan-Meier analyses, OS tended to be longer in the IPC- group than that in the IPC+group (NR vs 65 months, P = 0.0017). CONCLUSIONS Our results suggested significantly better OS in patients without IPC than that in those with IPC.

Abstract
Bisphenols are endocrine-disrupting chemicals found in a broad range of products that can modulate hormonal signalling pathways and various other biological functions. These compounds can bind steroid receptors, e.g. estrogen and androgen receptors, expressed by numerous cells and tissues, including the prostate and the bladder, with the potential to alter their homeostasis and normal physiological functions. In the past years, exposure to bisphenols was linked to cancer progression and metastasis. As such, recent pieces of evidence suggest that endocrine-disrupting chemicals can lead to the development of prostate cancer. Moreover, bisphenols are found in the urine of the wide majority of the population. They could potentially affect the bladder's normal physiology and cancer development, even if the bladder is not recognized as a hormone-sensitive tissue. This review will focus on prostate and bladder malignancies, two urological cancers that share standard carcinogenic processes. The description of the underlying mechanisms involved in cell toxicity, and the possible roles of bisphenols in the development of prostate and bladder cancer, could help establish the putative roles of bisphenols on public health.

Abstract
OBJECTIVE To investigate the oncological impact of incidental prostate cancer (iPCa) found during radical cystoprostatectomy (RCP) on overall survival (OS) prognosis of urothelial carcinoma of the bladder (BCa). PATIENTS AND METHODS A total of 122 RCP cases resected between 2002 and 2012 at our center were included for study. Survival of BCa patient was compared using the Kaplan-Meier method and the log-rank test. Cox proportional hazards regression models were used to analyze the impact of iPCa on the 5-year overall mortality of BCa patients after RCP. RESULTS Among the 122 BCa cases that underwent RCP, 38 cases (31.1%) had iPCa, in which, 17 cases (44.7%) were identified as clinically significant iPCa (csPCa). BCa patients with iPCa were older (71 vs 64 years, p = 0.004) and had higher preoperative PSA level (3.1 ng/mL vs 1.4 ng/mL, p = 0.017) when compared to those without iPCa. Cases with iPCa showed a more favorable 5-year OS than cases without iPCa, although this difference did not reach statistical significance (p = 0.219). When excluding the higher risk cases with Gleason score (GS) ≥ 4 + 3 and/or preoperative PSA > 10 ng/mL, BCa patients with iPCa showed a significantly longer OS than cases without iPCa on univariate analysis (p = 0.044), but not on multivariate analysis (p = 0.125). CONCLUSION Our results demonstrated that the frequent findings of low-risk iPCa in BCa patients could indicate the potential possibility of shared pathogenesis pathways between iPCa and BCa. Future study with a larger cohort is warranted to validate this result.

Abstract
Prostate cancer (PCa) is the second most common malignant tumors for male patients worldwide. However, whether a history of pre-existing cancer cases may affect the survival of prostate cancer patients is still not fully understood.We identified patients diagnosed with PCa between 2000 and 2014 from the Surveillance, Epidemiology, and End Results (SEER) linked database. We further made propensity score matching and then compared all-cause and cancer-specific survival between patients with and those without a pre-existing cancer. Cox proportional hazards models and Kaplan-Meier analysis were used for survival comparison.A total of 153,255 patients with PCa were included for analysis, of whom 5939 had a history of pre-existing cancer, including hematologic and lymph (11%), intestine (19%), urinary system (36%), head and neck (9%), lung (5%), skin (12%), and others (8%). Patients with a pre-existing cancer had a worse prognosis compared with those without a pre-existing cancer [all-cause death: hazard ratio (HR) = 2.74, P < .001; cancer-special death: HR = 3.98, P < .001]. Importantly, cancers in urinary bladder prior to PCa had a most adverse impact on all-cause (HR = 5.00, P < .001) and cancer-specific death risk (HR = 10.45, P < .001). Time between the pre-existing cancer and PCa had a dose-dependent effect on survival of PCa patients, with a decreased death risk as the increase of the interval time.Pre-existing cancer has a negative impact on the prognosis of patients with PCa, which is most evident in the presence of a pre-existing urinary bladder cancer. Our results provide epidemiologic evidence with low between-group bias, large sample size, and long-term follow-up, highlighting the need for site-, and interval-time-based clinical management for patients with PCa who had a pre-existing cancer.

Kwon WA, Joung JY, Lim J, Oh CM, Jung KW, Kim SH, Seo HK, Park WS, Chung J, Lee KH, Won YJ. Risk of second primary Cancer among bladder Cancer patients: a population-based cohort study in Korea. BMC Cancer 2018; 18:617. [PMID: 29855390 PMCID: PMC5984459 DOI: 10.1186/s12885-018-4530-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2017] [Accepted: 05/18/2018] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND For the expanding population of bladder cancer survivors in Korea, the development of subsequent cancers is a significant concern. Here, we provide the second primary cancer incidence rates and types in Korean patients with bladder cancer. METHODS Using population-based data from the Korea Central Cancer Registry from 1993 to 2013, we studied the standardized incidence ratios among 48,875 individuals with an initial diagnosis of bladder cancer. Standardized incidence ratios for second primary cancers were evaluated according to age at diagnosis, latency, diagnostic year, and treatment. RESULTS Over the same period, the overall risk of a second primary cancer was reduced by 6% in patients with bladder cancer compared with the development of a new malignancy in the general population (standardized incidence ratio = 0.94; 95% CI, 0.91-0.97, p < 0.05). For specific cancers, the standardized incidence ratios for stomach, colon, liver, and non-Hodgkin lymphoma were significantly lower in patients with bladder cancer. However, the risk of prostate and kidney cancer in patients with bladder cancer were significantly increased. The risk of lung squamous cell carcinoma and lung adenocarcinoma as second primary cancers was significantly elevated in patients with bladder cancer. CONCLUSION Korean patients with bladder cancer have a 6% lower risk of developing a second primary cancer. However, they have a higher risk of developing subsequent prostate and kidney cancers, lung squamous cell carcinoma, and lung adenocarcinoma, suggesting the need for continual intensive cancer surveillance among bladder cancer survivors.

Abstract
OBJECTIVES Investigate potential association between pioglitazone exposure and risk of prostate cancer. RESEARCH DESIGN AND METHODS Nested, matched case-control study. UK primary care data (Clinical Practice Research Datalink (CPRD) GOLD) linked to inpatient (Hospital Episode Statistics (HES)) and cancer registry (National Cancer Information Network (NCIN)) data. English men aged ≥40 years diagnosed with type 2 diabetes mellitus, January 1, 2001 to January 5, 2015. Cases, with prostate cancer diagnosis, matched with up to 4 controls by age, cohort entry date and region. ORs for association of exposure to pioglitazone to incident prostate cancer, adjusted for potential confounders. RESULTS From a cohort of 47 772 men with 243 923 person-years follow-up, 756 definite cases of prostate cancer were identified. Incidence was 309.9/100 000 person-years (95% CI 288.6 to 332.8). Pioglitazone use was not associated with prostate cancer risk; adjusted OR 0.759, 95% CI 0.502 to 1.148. Analyses showed no difference when possible cases, prostate cancer in CPRD GOLD only, included (adjusted OR 0.726, 95% CI 0.510 to 1.034). No association when adjusted for channeling bias (OR 0.778, 95% CI 0.511 to 1.184) or limited to an index date prior to July 1, 2011 (adjusted OR 0.508, 95% CI 0.294 to 0.879), despite prostate-specific antigen screening occurring more frequently among cases than controls (81.6% of 756 definite cases cf. 24.2% of 2942 controls (p<0.01)). No association with duration of pioglitazone use, increasing pioglitazone dose or increasing time since initiation. CONCLUSIONS In this real-world, nested matched case-control study, exposure to pioglitazone was not associated with increased risk of prostate cancer.

Androgen deprivation therapy prevents bladder cancer recurrence. Oncotarget 2015; 5:12665-74.

Abstract
Although accumulating preclinical evidence indicates the involvement of androgen receptor signals in bladder cancer (BC) development, its clinical relevance remains unclear. We aimed to evaluate the predictive role of androgen deprivation therapy (ADT) in BC recurrence in prostate cancer (PC) patients. We retrospectively reviewed 20,328 patients with PC diagnosed during 1991–2013 and identified 239 (1.2%) men having primary BC. After excluding ineligible patients, 162 patients made up a final cohort. With a median follow-up of 62 months, 38 (50%) of 76 control patients without ADT experienced BC recurrence, while 19 (22%) of 86 did in ADT group. Thus, patients having received ADT for their PC showed a significantly lower risk of BC recurrence (5-year actuarial recurrence-free survival: 76% v 40%; P < 0.001) and also had a significantly smaller number of recurrence episodes (5-year cumulative recurrence: 0.44 v 1.54; P < 0.001), compared to the control patients. A multivariable analysis revealed ADT as an independent prognosticator (hazard ratio, 0.29; 95% confidence interval, 0.17–0.49) for BC recurrence. This is the first clinical study showing that ADT significantly reduces the risk of BC recurrence.

Abstract
Purpose The objective was to investigate the clinicopathological characteristics and the prognosis of prostate cancer patients affected by other primary malignancies. Materials and Methods From 1990 to 2008, we retrospectively reviewed the medical records of 1,317 patients who underwent radical prostatectomy (RP) for prostate cancer. We assessed the effect of other primary malignancies on clinicopathological features, biochemical recurrence (BCR)-free survival, cancer-specific survival (CSS), and overall survival (OS). Results Of 1,317 patients, at least one additional other primary malignancy was detected in 187 patients (14.2%). A comparison of patient groups according to the presence or absence of other primary malignancies showed no significant differences in preoperative serum prostate-specific antigen concentrations, pathological Gleason scores, or pathological staging. Prostate cancer patients with other primary malignancies were older than patients without other primary malignancies (p<0.001). No significant differences in 5-year BCR-free survival (80.2% compared with 77.7%; p=0.656) or CSS (98.9% compared with 98.5%; p=0.733) were found between these groups, respectively. Five-year OS was significantly lower in prostate cancer patients with than in those without other primary malignancies (89.3% compared with 95.4%; p<0.001). Multivariate analysis showed that other primary malignancies diagnosed after RP for prostate cancer were independent predictors of OS (hazard ratio, 4.10; p<0.001) but not of BCR-free survival or CSS. Conversely, other primary malignancies diagnosed before RP for prostate cancer did not independently predict BCR-free survival, OS, or CSS. Conclusions Prostate cancer prognosis after RP is not dependent on the presence or absence of other primary malignancies. However, other primary malignancies diagnosed after RP for prostate cancer negatively affect OS.

Abstract
Second primary cancer (SPC) has become an increasing concern in cancer survivorship. Patterns of SPCs in different populations may offer clinical implications and research priorities into SPCs. This study is devoted to compare the occurrences and rank correlations of SPCs between Germany and Sweden. Patients diagnosed with 10 common first primaries between 1997 and 2006 from the Swedish Family-Cancer Database and 10 German cancer registries were included in this population-based study. Spearman's rank correlation coefficients were used to evaluate the strength of the relationship of SPCs between the German and Swedish datasets. Spearman's rank correlation coefficients suggested a strong positive correlation between the German and Swedish datasets based on the ranks of thirty possible SPCs after all selected first cancers. This was also true when we compared the rankings and proportions of the five most common SPCs after site-specific first primaries between the two populations. For kidney cancer, non-Hodgkin's lymphoma, and leukemia the components of the five most common SPCs was exactly the same. Also, the ranking and the proportions for the three most common SPCs (i.e., colorectal, bladder, and lung cancers) after prostate cancer were identical in the two populations, as were those after most other primary cancers. The strikingly consistent patterns of SPCs in the two populations provide excellent opportunities for joint studies and they also suggest that many underlying reasons for SPC may have universal and tangible causes that await mechanistic dissection.

A meta-analysis of the NAT1 and NAT2 polymorphisms and prostate cancer: a huge review. Med Oncol 2010; 28:365-76.

Abstract
Studies revealing conflicting results on the role of NAT1 or NAT2 phenotypes on prostate cancer risk led us to perform a meta-analysis to investigate the association of these polymorphisms and prostate cancer risk. The meta-analysis included six studies with NAT1 genotyping (610 prostate cancer cases and 713 controls), and 10 studies with NAT2 genotyping (1,253 cases and 1,722 controls). The fixed effects odds ratio was 0.96 [95% confidence interval (95% CI): 0.75, 1.21; I(2) = 32.9%, P for heterogeneity = 0.189] for the NAT1 genotype, and the random effects odds ratio was 1.10 (95% CI: 0.87, 1.39; I(2) = 49.1%, P for heterogeneity = 0.039) for the NAT2 genotype. For NAT2 polymorphism, a statistically significant association between NAT2 polymorphism and prostate cancer appeared in Asians, but not in Caucasians. In conclusion, the NAT1 or NAT2 phenotypes detoxify carcinogens and their reactive intermediates are unlikely to be the cause of PCa development.

Abstract
INTRODUCTION Prostate cancer is the most frequently diagnosed non-skin cancer in the United States and the third leading cause of cancer deaths. International trends in the incidence, mortality and prevalence of prostate cancer are assessed. METHODS Databases from the Surveillance, Epidemiology and End Results (SEER) program of the National Cancer Institute and the International Agency for Research on Cancer (IARC), and the literature on autopsy studies on prostate cancer were reviewed and summarized in the article. RESULTS Prostate cancer remains an important public health concern in Western countries and an emerging malignancy in developing nations. Prostate cancer incidence is dependent on efforts to detect the disease. Autopsy studies provide accurate and useful information regarding comparative prevalence rates of the disease among regions of interest. CONCLUSIONS Improved cancer registration is needed in developing nations. The prevalence of prostate cancer must be established to predict the expected incidence of the disease and in order to plan rational detection and treatment strategies. Clinically significant disease should be distinguished from insignificant disease which may pose little or no biological danger to the patient.

Abstract
The relationship between family history of cancer in first-degree relatives and risk of bladder cancer was examined in the Spanish Bladder Cancer Study. Information on family history of cancer was obtained for 1,158 newly diagnosed bladder cancer cases and 1,244 controls included in 18 hospitals between 1998 and 2001. A total of 464 (40.1%) cases and 436 (35.1%) controls reported a family history of cancer in >/=1 relative [odds ratio (OR), 1.32; 95% confidence interval (95% CI), 1.11-1.59]; the OR was 1.23 (95% CI, 1.01-1.50) among those with only one relative affected and 1.67 (95% CI, 1.23-2.29) among those with >/=2 affected relatives (P(trend) = 0.0004). A greater risk of bladder cancer was observed among those diagnosed at age </=45 years (OR, 2.67; 95% CI, 1.10-6.50) compared with those diagnosed over age 45 years (OR, 1.27; 95% CI, 1.06-1.52). The OR of bladder cancer among subjects reporting a family history of cancer of the bladder was 2.34 (95% CI, 0.95-5.77). Statistically significant associations emerged between bladder cancer risk and family history of cancer of the esophagus, lung, prostate, and brain. The OR of bladder cancer for those reporting family history of bladder cancer was 4.76 (95% CI, 1.25-18.09) among NAT2-slow acetylators and 1.17 (95% CI, 0.17-7.86) among NAT2-rapid/intermediate acetylators (P(interaction) = 0.609). Among individuals with GSTM1 null and present genotypes, the corresponding ORs were 2.91 (95% CI, 0.44-19.09) and 4.21 (95% CI, 1.26-14.14), respectively (P(interaction) = 0.712). Limitations of our study are small sample size in subgroup analyses, reliability of family history data, and possible residual confounding by shared environmental exposures. Overall, our findings support the hypothesis that genetic factors play a role in bladder cancer etiology. Whether these correspond to low-penetrance cancer-predisposing polymorphisms acting together and/or interacting with environmental factors warrants further research.

Abstract
OBJECTIVE To assess the occurrence of both bladder and prostate tumours in five well defined cancer registries. METHODS Anonymous data were provided from each cancer registry on all male bladder and prostate cancers (invasive and non-invasive). Poisson regression was used to model the rate of developing the second primary tumour and generated incidence rate ratios (RRs) with 95% confidence intervals. RESULTS For bladder cancer and prostate cancer as first diagnosis, there was an excess risk to develop the second neoplasm. The RR decreased with increasing age of the patients. No effect of the initial treatment of the first neoplasm was found. CONCLUSION This analysis found an excess risk to develop prostate cancer in bladder cancer patients younger than 70 years and the first year of follow-up after the diagnosis of bladder cancer. This may be due to detection bias, although a common aetiology may also be present.

Abstract
INTRODUCTION We estimate the frequency of prostate cancers detected incidentally in radical cystoprostatectomy specimens and discuss whether the prostate cancer status should be determined in patients undergoing radical cystoprostatectomy. MATERIALS AND METHODS A total of 97 radical cystoprostatectomies without evidence of prostate cancer on digital rectal examination were performed for transitional cell carcinomas of the bladder between January 2001 and May 2004. The mean patient age at the time of surgery was 66.9 +/- 9.52 (range 49-75) years. RESULTS The overall incidence of prostate cancer detected in radical cystoprostatectomy specimens was 21.6% (21/97 specimens). The mean tumor volume was found to be 0.93 +/- 0.81 ml. The tumor volume was >0.5 ml in 12 cases (57.1%). The surgical margin was negative in all cases, and the disease was organ confined in 20 patients (95.2%). Capsular invasion was evident in 2 patients (9.5%), 1 of whom had lymph-node-positive disease. CONCLUSIONS Despite the high prevalence of incidental prostate carcinomas among patients with bladder cancer undergoing cystoprostatectomy, the vast majority of the cancers are organ confined. However, the prostate cancer status should be determined on the basis of digital rectal examination and prostate-specific antigen in patients undergoing radical cystoprostatectomy - especially if prostate-sparing cystectomy is planned.

Abstract
OBJECTIVES Radical cystectomy has been the reference standard for the treatment of muscle-invasive bladder cancer. However, this kind of therapy does have an impact on the patient's quality of life. For this reason, we performed prostate-sparing surgery during radical cystectomy without compromising the oncologic outcome. METHODS From December 2003 to August 2005, 31 patients with a mean age of 63.6 +/- 8 years (range 48 to 79) underwent apex-sparing radical cystoprostatectomy for invasive bladder cancer. All patients underwent transurethral biopsy in the prostatic urethra to exclude urothelial tumor and transrectal ultrasound-guided biopsy of the prostate to diagnose concomitant prostate cancer. Patients with a prostate-specific antigen level greater than 4 ng/mL were excluded from prostate-sparing cystectomy. The mean follow-up period was 12 months. RESULTS The postoperative pathologic stage was pTis in 2 patients, pTa in 1, pT1 in 3, pT2 in 20, pT3 in 5, and pN+ in 4 patients. We found no prostate cancer on histopathologic evaluation. Except for 4 patients, no patient had deterioration of sexual function. Except for 2 patients, all patients were fully continent. CONCLUSIONS Radical cystectomy with prostate-sparing surgery in patients with invasive bladder cancer resulted in improved continence and improved erectile function. Additionally, with apex-sparing radical cystoprostatectomy, we were able to create a wide neovesicourethral anastomosis to prevent strictures, urinary retention, and mucous retention. It is absolutely necessary that this procedure be restricted to highly selected patients.

Median follow-up was 10.5 years. Patients were followed for the development of lower genitourinary and colorectal cancers. Second malignancies arising five years after radiation therapy were defined as being potentially associated with treatment; observed rates were then compared with age-matched expected rates according to Surveillance, Epidemiology, and End Results data. RESULTS Five years out of treatment, there were 15 patients with a second solid tumor, including bladder cancer (n = 11), colorectal cancer (n = 3), and prostatic urethra cancer (n = 1). The incidence of second malignancy was no different in patients treated with brachytherapy alone (1.6%) vs. those receiving external beam radiotherapy (5.8%, p = 0.0623). There were more observed bladder cancers compared with those expected (relative risk, 2.34, 95% confidence interval 0.96-3.72; absolute excess risk 35 cancers per 10,000 patients). Relative risk did not significantly change over increasing follow-up intervals up to 20 years after treatment. CONCLUSIONS There may be an increased but small risk of developing a second malignancy after radiation therapy for prostate cancer. This outcome could be related to radiation carcinogenesis, but more vigilant screening and thorough workup as a result of radiation side effects and predisposing conditions (e.g., genetic and environmental factors) in many of the patients found to have second malignancies likely contributed to the higher number of observed malignancies than expected.

Abstract
PURPOSE We reviewed the clinical course of patients in whom urothelial carcinoma developed following radiation therapy for prostate cancer. MATERIALS AND METHODS A retrospective review of all patients between 1990 and 2005 with the diagnosis of bladder and prostate cancer was performed. Of 125 total patients new onset urothelial carcinoma developed in 11 after undergoing external beam radiation therapy for prostate cancer. RESULTS Whole pelvis external beam radiation therapy with a proton boost to the prostate was the radiation modality in 7 of the 11 patients (64%), while the remaining 4 patients received standard external beam radiation only. Urothelial carcinoma was detected a mean of 3.07 years after completion of radiation therapy in the proton group, compared to a mean latency period of 5.75 years in the standard radiation group (p = 0.09). Average patient age at diagnosis was 72 years (range 64 to 84). All patients presented with gross hematuria and had cystoscopic findings of coexisting radiation cystitis. Of the 11 patients 5 (45%) presented with grade 3 carcinoma and eventually 7 (64%) required radical cystectomy. Urothelial tumors with sarcomatoid features (carcinosarcoma and spindle cell sarcomatoid) developed in 2 patients (18%). Of the 11 patients 10 (91%) were nonsmokers at the time of urothelial carcinoma diagnosis. CONCLUSIONS Urothelial carcinoma in patients with previous radiation therapy for prostate cancer is often high grade, and the majority of patients have cancer progression requiring cystectomy. A high incidence of urothelial carcinoma with sarcomatoid features was seen in these patients.

Abstract
PURPOSE Prostate cancer is the most common male malignancy and the second leading cause of male cancer death; therefore, there is urgent necessity for noninvasive assays for early detection of prostate cancer. Obtaining prostate tumor samples surgically is problematic because the malignancy is heterogeneous and multifocal and early-stage tumors are nonpalpable. In contrast, exfoliated cells represent the cancer status of the entire gland better due to the general tendency of cancer cells to exfoliate into biological fluids. The purpose of this study was to clarify whether quantitative analysis of telomerase activity in exfoliated cells in urine could serve as a reliable molecular marker of prostate malignancy. EXPERIMENTAL DESIGN We analyzed prospectively post-prostatic examination-exfoliated cells from the urine of 56 patients undergoing routine prostate screening. Epithelial cells were isolated and enriched by immunomagnetic separation. Telomerase activity was analyzed by quantitative real-time PCR telomeric-repeat amplification protocol assay using Opticon MJ research instrument. RESULTS We report now that all prostate cancer patients revealed high levels of telomerase activity thereby showing 100% of the assay sensitivity. In contrast, the majority of patients with clinically confirmed benign prostatic hyperplasia (BPH) did not express any telomerase activity (70% of all BPH patients), most likely presenting cancer-free cases, or expressed low levels of activity (18%). However, about 12% of BPH patients revealed high levels of telomerase activity that potentially can reflect hidden prostate cancer. CONCLUSIONS We suggest that the quantitative analysis of telomerase activity can be useful for the selection of prostate cancer and cancer-free cases.
