Background: Tumor necrosis factor-alpha (TNF) is an inflammatory cytokine implicated in the development of many chronic inflammatory diseases and TNF-α inhibitors (TNF-I) are frequently prescribed as treatment. Their malignancy risk is debated, with pro-oncogenic effects of decreased immune surveillance and anti-oncogenic effects of decreasing chronic inflammation. As such, the literature is inconclusive in the malignancy risk of these medications.

Objectives: The objective of this study is to evaluate preoperative factors associated with cardiopulmonary bypass (CPB) utilization and outcomes for patients with renal cell carcinoma (RCC) and tumour thrombus (TT). Radical nephrectomy with thrombectomy is a standard treatment for patients with RCC and associated TT. Morbidity and mortality rates tend to correlate with aggressiveness of tumour and TT level.

Background And Objectives: This study evaluates the prognostic value of venous tumor thrombus (VTT) in patients with advanced renal cell carcinoma (RCC) undergoing radical resection and inferior vena cava (IVC) thrombectomy.

Methods: Retrospective review of patients with radical nephrectomy for RCC and associated VTT (2000-2024). Patients were dichotomized into Neves 0-II (infrahepatic) and Neves III-IV groups (suprahepatic) IVC involvement for univariate analysis.

Background And Objectives: Partial (PN)/radical (RN) nephrectomy is the standard treatment for localized renal-cell carcinoma (RCC). The potential risks of these procedures are concerns for the elderly. We evaluated perioperative outcomes/survival for patients aged ≥ 75 years with localized RCC who underwent PN, RN, or thermal ablation (TA).

Background: Receiving a diagnosis of cancer is a profound and often very stressful experience. Few studies have prospectively recruited patients prior to receiving a new diagnosis of cancer and included spouses or partners.

Objective: The aim of the Couples Cope Study is to understand the impact of undergoing a diagnostic biopsy and receiving a new cancer diagnosis on quality of life (QoL) in both patients and their spouses or partners, as well as on the quality of their relationship.

Background And Objective: The transrectal biopsy approach is traditionally used to detect prostate cancer. An alternative transperineal approach is historically performed under general anesthesia, but recent advances enable transperineal biopsy to be performed under local anesthesia. We sought to compare infectious complications of transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis.

To identify symptom burden profiles among men with advanced prostate cancer undergoing androgen-deprivation therapy and examine their association with baseline sociodemographic and medical characteristics and psychosocial outcomes over time. Latent profile analysis was employed to identify distinct groups based on the Expanded Prostate Index Composite and the McGill Pain Questionnaire at baseline. Psychosocial outcomes were assessed at baseline, 6- and 12-month follow-ups.

Article Synopsis
  • Men with low-risk prostate cancer are increasingly choosing active surveillance (AS) instead of immediate treatment, but many later switch to active treatment.
  • A multi-institutional study analyzed genetic data from over 5,000 prostate cancer patients who opted for AS to identify genetic factors that might predict those likely to switch to treatment.
  • The study found 18 genetic variants related to the decision to change treatment and established a link between certain genetic risk scores and the likelihood of converting from AS to active treatment, suggesting that genetics could personalize monitoring and treatment decisions for these patients.

Background: Recent studies suggest an association between prostate cancer and inflammatory bowel disease (IBD). Our objectives were to investigate clinical and financial impacts of IBD on radical prostatectomy (RP) and to determine the impact of surgical approach on our findings.

Methods: The Premier Hospital Database was queried for patients who underwent RP from 2003 to 2017.

Background: Despite consensus guidelines, many men with low-grade prostate cancer are not managed with active surveillance. Patient perception of the nomenclature used to describe low-grade prostate cancers may partly explain this discrepancy.

Methods: A randomized online survey was administered to men without a history of prostate cancer, presenting a hypothetical clinical scenario in which they are given a new diagnosis of low-grade prostate cancer.

Article Synopsis
  • Chronic intestinal inflammation in patients with inflammatory bowel disease (IBD) is linked to changes in the prostate that could promote tumor formation, evidenced by greater lymphocyte infiltration in prostate tumors of men with IBD compared to non-IBD patients.
  • In mouse models, chronic colitis led to increased leukocyte infiltration and activation of pro-inflammatory signaling pathways like AKT and NF-kB in the prostate, indicating a pro-tumor environment.
  • The study highlights that ongoing gut inflammation may contribute to prostate cancer development in IBD patients by creating an inflammatory environment that can damage DNA and disrupt normal cell cycles in prostate cells.

Unlabelled: Cognitive behavioral stress management (CBSM) improves quality of life and mitigates stress biology in patients with early-stage cancer, including men with localized prostate cancer. However, treatments for advanced prostate cancer like androgen deprivation therapy (ADT) can lead to significant symptom burden that may be further exacerbated by stress-induced inflammation and cortisol dysregulation. The aim of this study was to examine the effects of CBSM (versus an active health promotion control) on circulating inflammatory markers and cortisol in men with advanced prostate cancer.

Introduction: We sought to assess the impact of Affordable Care Act Dependent Care Expansion (ACA-DCE), which allowed dependent coverage for adults aged 19-25, and Medicaid expansion on outcomes for men with testicular cancer.

Methods: Using a US-based cancer registry, we performed adjusted difference-in-difference (DID) analyses comparing outcomes between men aged 19-25 (n = 8,026) and 26-64 (n = 33,303) pre- (2007-2009) and post-ACA-DCE (2011-2016) and between men in states that expanded Medicaid (n = 2,296) to men in those that did not (n = 2,265)pre- (2011-2013) and post-Medicaid expansion (2015-2016).

Results: In ACA-DCE analysis, rates of uninsurance decreased (DID -5.

Leiomyosarcomas are an uncommon malignant subset of tumors accounting for approximately 20% of soft tissue sarcomas. Primary vascular leiomyosarcomas (PVLs) are a rare subset of leiomyosarcomas that may originate in the arterial or venous circulation but most commonly affect the inferior vena cava (IVC). PVLs more commonly affect women to men in a 2:1 ratio and most frequently occur in the fourth to sixth decades of life.

Article Synopsis
  • * The research followed 218,084 men aged 40-69 from the UK Biobank and found that those with IBD had a higher risk of developing PC, particularly those with ulcerative colitis (UC).
  • * The findings suggest an adjusted hazard ratio (aHR) of 1.31 for overall IBD, with a stronger association of aHR = 1.47 for UC, indicating a need for further research due to some limitations, including lack of data on healthcare interactions.

Glomus tumor of the scrotal skin is an extremely rare diagnosis in adult men with only five previous cases reported in the literature. We report the case of a 19-year-old man who was diagnosed with a glomus tumor following the surgical removal of a painful scrotal lesion, and further discuss the diagnosis and treatment of scrotal glomus tumors.

Introduction: The absence of health insurance coverage has been associated with worse outcomes for patients with metastatic renal cell carcinoma (mRCC). Medicaid expansion in the United States was an important provision of the Affordable Care Act, which increased the number of low-income individuals eligible for Medicaid starting in January 2014 in several states. The effect of Medicaid expansion on access to healthcare for patients with mRCC is unknown.

Background: Men with advanced prostate cancer (APC) face multiple challenges including poor prognosis, poor health-related quality of life (HRQOL), and elevated symptom burden. This study sought to establish the efficacy of a tablet-delivered, group-based psychosocial intervention for improving HRQOL and reducing symptom burden in men with APC. We hypothesized that men randomized to cognitive-behavioral stress management (CBSM) would report improved HRQOL and reduced symptom burden relative to men randomized to an active control health promotion (HP) condition.
