AI Article Synopsis
- A case study reports the occurrence of three different types of renal cell carcinomas simultaneously found in a single kidney of a 44-year-old man with end-stage renal disease.
- Preoperative imaging techniques, like enhanced CT scans, may miss the presence of multiple tumors, as the man was initially diagnosed with only one tumor.
- The findings suggest that patients with significant kidney issues should be monitored for multiple types of renal cell carcinomas, even if only one tumor is detected through imaging.
Article Abstract
Introduction: Few reports have presented sporadic multifocal renal cell carcinomas of different histologic types occurring simultaneously in a single kidney. Here, we present a case of three ipsilateral renal cell carcinomas with three histologic types.
Case Presentation: A 44-year-old man with end-stage renal disease due to nephrosclerosis was referred to our hospital for an incidental renal tumor. Following the introduction of hemodialysis, enhanced computed tomography revealed a renal tumor suggestive of clear-cell renal cell carcinoma with a cystic component. With a preoperative diagnosis of one renal tumor, he underwent laparoscopic radical nephrectomy. However, pathological examination revealed three renal cell carcinomas with three histological diagnoses: clear-cell, papillary, and clear-cell papillary renal cell carcinomas.
Conclusion: Preoperative imaging may not detect all synchronous ipsilateral multifocal renal cell carcinomas. Patients with severe renal function impairment may have synchronous multifocal renal cell carcinomas.

Objectives: To study the significance of serum 25-hydroxyvitamin D [25-(OH)D] level in the clinicopathological characteristics and prognosis of children with immunoglobulin A vasculitis nephritis (IgAVN).
Methods: A retrospective analysis was conducted on the clinical data of children with IgAVN who underwent renal biopsy at Suzhou Hospital Affiliated to Anhui Medical University and Jinling Hospital of the Medical School of Nanjing University from June 2015 to June 2020. Based on serum 25-(OH)D level, the patients were divided into a normal group and a lower group.
ADAR1 Promotes the Progression and Temozolomide Resistance of Glioma Through p62-Mediated Selective Autophagy.

Background: Resistance to temozolomide (TMZ) remains is an important cause of treatment failure in patients with glioblastoma multiforme (GBM). ADAR1, as a member of the ADAR family, plays an important role in cancer progression and chemotherapy resistance. However, the mechanism by which ADAR1 regulates GBM progression and TMZ resistance is still unclear.

Introduction: Pseudotumors are benign lesions which may mimic like a malignant tumor on conventional imaging. They are formed in kidneys which are scarred and deformed by chronic pyelonephritis, glomerulonephritis, trauma or infarction. There is a diagnostic dilemma in most of the cases as to differentiate RCC and pseudotumors.

Clear cell renal cell carcinoma (ccRCC) is characterised by significant genetic heterogeneity, which has diagnostic and prognostic implications. Very limited evidence is available regarding DNA methylation heterogeneity. We therefore generate sequence level DNA methylation data on 136 multi-region tumour and normal kidney tissue from 18 ccRCC patients, along with matched whole exome sequencing (85 samples) and gene expression (47 samples) data on a subset of samples.

Advancements in microbiome research reveal its impact on cancer treatment outcomes, particularly in renal cell carcinoma (RCC). While immune checkpoint inhibitors (ICIs) have improved survival in metastatic RCC, composition of the gut microbiome has the potential to influence their efficacy. Antibiotic-induced microbiome disruptions correlate with diminished outcomes, while strains such as Akkermansia muciniphila, Clostridium butyricum, and others enhance immune responses and progression-free survival.
