Objective: To investigate the outcome of conservative therapy in men presenting with voiding symptoms and prostate cancer.
Methods: A consecutive series of 186 men presenting with voiding symptoms and prostate cancer were treated with transurethral resection (TUR). Examination of the resected tissue revealed 70 nonpalpable prostate cancers and confirmed the clinical suspicion of prostate cancer in 116 palpable tumors; 47 tumors were well differentiated, 87 intermediate and 52 poorly differentiated. Bone scan indicated metastasis in 24 men, all asymptomatic. The men were followed and underwent orchidectomy if symptoms of generalized disease appeared.
Results: After a follow-up of 13-21 years, 172/186 (92%) of the men had died, with 80/186 (43%) of the men dying of prostate cancer. The mean life expectancy was 6.3 years (confidence interval 5.4-7.1) compared with 10.2 years of an age-matched control group. In a subgroup of men with clinically localized disease, 26/97 (27%) died of prostate cancer. These men had a mean life expectancy of 7.1 years (confidence interval 6.0-8.3). Tumor stage and grade were highly significant predictors for cause-specific survival in uni- and multivariate analysis. Death from prostate cancer continued to occur beyond 10 years after diagnosis at a decreasing rate.
Conclusions: Patients with prostate cancer causing voiding symptoms at presentation severe enough to necessitate TUR had a less favorable outcome than asymptomatic patients with prostate cancer in previously reported series, even when stratified for stage and grade. It is suggested that voiding symptoms at diagnosis are a putative prognostic factor in prostate cancer.

Background: The metal oxide nanoparticles possess unique properties such as biological compatibility, superior reactivity, and capacity to develop reactive oxygen species, due to this they have drawn significant interest in cancer treatment. The various MONPs such as cerium oxide, Copper oxide, Iron oxide, Titanium dioxide, and Zinc oxide have been investigated for several types of cancers including brain, breast, cervical, colon, leukemia, liver, lung, melanoma, ovarian, and prostate cancers. However, traditional physiochemical synthetic methods for MONPs commonly include toxic materials, a major concern that raises questions regarding their biocompatibility and safety.

Aims: We aimed to perform a retrospective cohort study using the Centers for Disease Control and Prevention's (CDC's) Wide-Ranging Online Data for Epidemiologic Research (WONDER) database to analyse the trends in cardiovascular disease (CVD)-related mortality in patients with myeloproliferative neoplasms (MPNs) from 1999 to 2020.
Methods And Results: We analysed the death certificate data from the CDC WONDER database from 1999 to 2020 for CVD with co-morbid myeloproliferative disorders in the US population. Age-adjusted mortality rates (AAMRs) and 95% confidence intervals (CIs) were computed per 1 million population by standardizing crude mortality rates to the 2000 US census population.

Doublecortin-like kinase 1 (DCLK1) has been revealed to be involved in modulating cancer stemness and tumor progression, but its role in prostate cancer (PCa) remains obscure. Castration-resistant and metastatic PCa exhibit aggressive behaviors, and current therapeutic approaches have shown limited beneficial effects on the overall survival rate of patients with advanced PCa. This study aimed to investigate the biological role and potential molecular mechanism of DCLK1 in the progression of PCa.

Biochemical recurrence (BCR) is a critical concern in prostate cancer management; however, its underlying genetic determinants remain poorly understood. The () gene family is involved in cellular detoxification and biosynthetic processes and has been implicated in various cancers. This study investigated the association between the family members and prostate cancer recurrence.

The association of prostate cancer with deranged lipid profile and insulin levels is inconsistent and not well understood. This study aimed to analyze the serum levels of lipids, insulin, insulin-like growth factor-1 (IGF-1) and testosterone and to identify their association with the risk of benign prostatic hyperplasia, prostate cancer and its grading.
