The causal effect of serum amino acids on the risk of prostate cancer: a two-sample mendelian randomization study.

Prostate cancer (PCa) is the second most common malignancy affecting men globally. Recent advances in metabolomics have highlighted significant alterations in specific amino acid (AA) metabolism linked to PCa, indicating their potential utility in diagnosis and therapy. However, no direct causal association between serum AA levels and PCa risk has been established.

IGF2BP2 inhibits invasion and migration of clear cell renal cell carcinoma via targeting Netrin-4 in an mA-dependent manner.

Clear cell renal cell carcinoma (ccRCC), the most common subtype of renal cell carcinoma, often leads to a poor prognosis due to metastasis. The investigation of N6-methyladenosine (mA) methylation, a crucial RNA modification, and its role in ccRCC, particularly through the mA reader insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2), revealed significant insights. We found that IGF2BP2 was notably downregulated in ccRCC, which correlated with tumor aggressiveness and poor prognosis.

Mortality Increases When Radical Nephrectomy is Delayed More Than 60 Days for T3 Renal Cell Carcinoma.

Radical nephrectomy is widely accepted as the default management option for patients with T3 renal cell carcinoma (RCC). However, it may require a certain time before surgery for various reasons. There are concerns that the delay in surgery may affect postoperative outcomes.

Impact of Surgical Wait Time on Survival in Patients With Upper Urinary Tract Urothelial Carcinoma With Hydronephrosis.

Background And Objectives: Due to the inevitability of waiting time for surgery, this problem seems to have become more pronounced since the outbreak of COVID-19, and due to the high incidence of preoperative hydronephrosis in upper urinary tract urothelial carcinoma (UTUC) patients, it is particularly important to explore the impact of preoperative waiting time and hydronephrosis on upper urinary urothelial carcinoma.

Methods: 316 patients with UTUC who underwent radical surgery at a high-volume center in China between January 2008 and December 2019 were included in this study. We retrospectively collected the clinicopathologic data from the medical records, including age, sex, smoking history, ECOG performance status (ECOG PS), body mass index (BMI), tumor location and size, number of lesions, T stage, N stage, surgical approach and occurrence of hydronephrosis, lymph node invasion, lymph node dissection, surgical margin, tumor necrosis, infiltrative tumor architecture, lymphovascular invasion and concomitant bladder cancer.

Safety of Prolonged Wait Time for Nephrectomy for Clinically Localized Renal Cell Carcinoma.

Background: There is usually a surgical wait time before nephrectomy for patients with clinically localized renal cell carcinoma, and many factors can influence this preoperative wait time. A relatively prolonged wait time may cause tumor progression. Therefore, we assessed the effect of preoperative wait time on the prognosis of patients with clinically localized renal cell carcinoma.

Metastases to the Kidney: An Analysis of 35 Cases and a Review of Literature.

Introduction: In addition to being rare, metastases to the kidney present clinicians with issues regarding their treatment.

Risk factors for survival in patients with von Hippel-Lindau disease.

Background: Historically, von Hippel-Lindau (VHL) disease is characterised by a poor survival. Although genotype-phenotype correlation has been described in many studies, the risk factors for VHL survival remain unclear. This study aims to evaluate the median survival of Chinese patients with VHL disease and explore whether VHL survival is influenced by genetic and clinical factors.

Shorter telomere length increases age-related tumor risks in von Hippel-Lindau disease patients.

Von Hippel-Lindau (VHL) disease is a rare autosomal dominant cancer syndrome caused by alterations of VHL gene. Patients are predisposed to develop pheochromocytomas and solid or cystic tumors of the central nervous system, kidney, pancreas, and retina. Remarkable phenotypic heterogeneity exits in organ involvement and tumor onset age between and within VHL families.
