PURPOSE: There are no well-established re-treatment options for local recurrence after primary curative radiation therapy for prostate cancer (PCa), as prospective studies with long-term follow-up are lacking. Here, we present results from a prospective study on focal salvage reirradiation with external-beam radiation therapy with a median follow-up of 7.2 years. MATERIALS AND METHODS: From 2013 to 2017, 38 patients with biopsy-proven locally recurrent PCa >2 years after previous treatment and absence of grade 2-3 toxicity from the first course of radiation were included...

BACKGROUND: Appendectomy is a common surgical procedure to treat appendicitis. Limited studies examined its association on prostate cancer, with one large cohort study suggesting significant increased risk of overall and advanced prostate cancer, especially among younger men. METHODS: A total of 49,104 men in the Health Professionals Follow-up Study were followed from 1986 to 2016. Cox proportional hazards models were applied to evaluate the association between self-reported history of appendectomy and risk of overall and subtype specific prostate cancer, adjusted for multiple risk factors...

Cancer screening behaviors in Muslims are under-researched, and there is limited data on how it relates to their unique cultural and religious beliefs. We assessed cancer prevention and screening-related health needs in the Washington DC area. We developed the needs assessment questionnaires and recruitment strategy in collaboration with key faith leaders from four mosques in our catchment area. A total of 203 participants were recruited through community outreach and engagement approaches and were included in the discussion when developing the needs assessment to ensure questions were religiously and culturally sensitive...

PURPOSE OF REVIEW: Our review delves into the progress across urological malignancies and discusses ongoing challenges and future directions in antibody-drug conjugate (ADC) development, emphasising their transformative potential in cancer care. RECENT FINDINGS: ADCs have advanced from hematologic to solid tumours, notably in breast cancer, and are now pivotal in metastatic urological cancers as both monotherapies and in combination regimens, underscored by the FDA's approval of enfortumab vedotin and sacituzumab govitecan for metastatic urothelial cancer...

Prostate cancer is a leading diagnosis and major cause of cancer-related deaths in men worldwide. As a typical hormone-responsive disease, prostate cancer is commonly managed with androgen deprivation therapy (ADT) to curb its progression and potential metastasis. Unfortunately, progression to castration-resistant prostate cancer (CRPC), a notably more aggressive phase of the disease, occurs within a timeframe of 2-3 years following ADT. Enzalutamide, a recognized androgen receptor (AR) antagonist, has been employed as a standard of care for men with metastatic castration-resistant prostate cancer (mCRPC) since it was first approved in 2012, due to its ability to prolong survival...

PURPOSE: Aimed to investigate the role of multiparametric magnetic resonance imaging (mp-MRI) in the diagnosis of granulomatous prostatitis caused by intravesical Bacillus Calmette-Guérin (BCG). METHODS: In this prospective, single-center study, 10 male patients who were given intravesical BCG due to intermediate- and high-risk bladder cancer were included. Before transurethral resection of bladder tumors (TURB), all patients were evaluated by mp-MRI, serum prostate-specific antigen (PSA), and digital rectal examination (DRE)...

Na, K-ATPase interaction (NKAIN) is a transmembrane protein family, which can interact with Na, K-ATPase β1 subunit. NKAIN1 plays an important role in alcohol-dependent diseases such as endometrial and prostate cancers. However, the relationship between NKAIN1 and human breast cancer has not been studied. Hence, this study aimed to explore the relationship between NKAIN1 expression and breast cancer. Data used in this study were mainly from the Cancer Genome Atlas, including differential expression analysis, Kaplan-Meier survival analysis, receiver operating characteristic curve analysis, multiple Cox regression analysis, co-expression gene analysis, and gene set enrichment analysis...

Dear Editor, Ticks carry many diseases, bacteria, and viruses and represent a very important healthcare issue both in Croatia and globally. Although most ticks are not infected with pathogens dangerous to humans, some ticks can transmit infectious diseases with significant morbidity and mortality. This is caused by the increasing incidence of many tick-borne diseases over a growing geographical area. Many factors influence which species of ticks are present in a given geographical area, as well as the density of their population and the risk of human exposure to infected ticks...

PURPOSE: Prostate-specific membrane antigen (PSMA)-targeting PET radiotracers reveal physiologic uptake in the urinary system, potentially misrepresenting activity in the prostatic urethra as an intraprostatic lesion. This study examined the correlation between midline 18F-DCFPyL activity in the prostate and hyperintensity on T2-weighted (T2W) MRI as an indication of retained urine in the prostatic urethra. PATIENTS AND METHODS: Eighty-five patients who underwent both 18F-DCFPyL PSMA PET/CT and prostate MRI between July 2017 and September 2023 were retrospectively analyzed for midline radiotracer activity and retained urine on postvoid T2W MRIs...

Prostate cancer is the most common cancer among Swedish men. To get this diagnose is not only a threat to the men's lives but also to their quality of life because the treatment often affects sexuality, bladder function and bowel function. It is therefore particularly problematic that the rehabilitation of men after treatment for prostate cancer often does not reach the standards set out in the national guidelines. Despite the past years' promotion of standardized cancer care pathways to speed up the process of investigating and treating cancer, the lead times for men who are being investigated for a suspicion of prostate cancer, or are waiting for a planned prostate cancer treatment, are the longest in Swedish cancer care...

The treatment of metastatic prostate  cancer has seen drastic changes in the recent years with more intense treatment at initial diagnose. The new standard is combination therapy with castration as the backbone and the addition of new hormonal therapies with or without chemotherapy. For patients with minimal metastatic spread it is also recommended to give radiotherapy to the primary tumour. Since many patients now can look forward to longer survival it is paramount to take care of the side-effects of the treatments, where focus is on cardiovascular disease and bone health management...

This study discusses the synthesis and use of a new library of spirooxindole-benzimidazole compounds as inhibitors of the signal transducer and activator of p53, a protein involved in regulating cell growth and cancer prevention. The text includes the scientific details of the [3 + 2] cycloaddition (32CA) reaction between azomethine ylide 7a and ethylene 3a within the framework of Molecular Electron Density Theory. The mechanism of the 32CA reaction proceeds through a two-stage one-step process, with emphasis on the highly asynchronous transition state structure...

Performing a radical treatment of prostate cancer in patients with a history of transurethral resection of the prostate (TURP) is a serious task even for an experienced surgeon, due to the anatomical and topographic changes that occur after endoscopic surgery. The technical possibilities of robotic technologies have great potential for obtaining the best treatment results for this category of patients. In order to review the intra- and postoperative outcomes of robot-assisted radical prostatectomy (RARP) in patients with a history of PCa and TURP, we selected relevant publications in the PubMed and Google Scholar databases for the period from 2008 to 2022...

AIM: To evaluate the effect of antibacterial prophylaxis using oral fosfomycin during the removal of a urethral catheter after radical prostatectomy on the development of urinary tract infection, severity of leukocyturia and bacteriuria, as well as the severity of lower urinary tract symptoms. MATERIALS AND METHODS: A single-center, non-blind, prospective, randomized controlled trial was carried out. The main group included 40 patients, and the control group included 37 patients...

There is a long history of curative treatment of prostate cancer. However, as prostate cancer often grows very slowly, and symptoms do not have time to develop during a person's lifetime, a more tentative approach has become more and more common in many cases. This may be through either watchful waiting or active surveillance. In the first case palliative hormonal treatment is given in the case of progression, in the latter curative treatment would be the choice. When treatment is deemed necessary for localized disease, surgery and radiotherapy are considered equivalent in terms of efficacy and overall risk of side effects...

Prostate cancer, prevalent among males, is influenced by various molecular factors, including Growth Differentiation Factor 15 (GDF15). Despite its recognized role in multiple tumor types, GDF15's specific involvement in prostate cancer remains insufficiently explored. This study investigates the regulatory function of GDF15 in prostate cancer. To explore GDF15's impact, we established GDF15 knockdown and overexpression models in prostate cancer cells. We quantified mRNA and protein levels using RT-PCR and Western blotting...

Many cancers, including prostate cancer, have miRNAs with altered expression levels. These miRNAs play a pivotal role in regulating cancer initiation, invasion, and metastasis. miRNAs are an important component in cancer diagnosis and therapy and can play a key role as biomarkers or chemotherapeutic agents.  This investigation aimed to show the effects of miR-375 on PCa. In this project, target prediction tools and the KEGG pathway were performed to determine the potential targets of miR-375. Transfection was performed using miR-375 mimic and inhibitor...

PURPOSE: Prostate biopsy is central to the accurate histological diagnosis of prostate cancer. In current practice, the biopsy procedure can be performed using a transrectal or transperineal route with different technologies available for targeting of lesions within the prostate. Historically, the biopsy procedure was performed solely by urologists, but with the advent of image-guided techniques, the involvement of radiologists in prostate biopsy has become more common. Herein, we discuss the pros, cons and future considerations regarding their ongoing role...

PURPOSE: Stress urinary incontinence (UI) often develops after radical prostatectomy for prostate cancer, and in those patients with moderate-to-severe stress UI an artificial urinary sphincter (AUS) is implanted. Inguinal hernias (IHs) often occur after radical prostatectomy. As the prevalence of AUS implantation increases, it is possible to encounter patients with IHs undergoing AUS implantation (IHA). This study investigated our treatment and discussed an appropriate approach for IHAs...
