Bladder cancer is rare in the pediatric population, and clear cell carcinoma is extremely rare with one other pediatric case reported. Here we report the clinical outcome for a medically complicated pediatric patient with muscle invasive clear cell carcinoma treated with partial cystectomy without neoadjuvant or adjuvant therapy. Final pathology was stage T2bN0M0 with negative margins. At 2 years, there is no disease recurrence by cystoscopy, chest and abdominal imaging. Postoperative issues have been related to reduced bladder capacity and compliance and the patient is currently managed with continuous urinary diversion and will require future definitive lower tract reconstruction.

Background: The most common malignant type of kidney cancer is clear cell renal cell carcinoma (ccRCC). The expression levels of hyaluronan-mediated motility receptor (HMMR) in many tumor types are significantly elevated. HMMR is closely associated with tumor-related progression, treatment resistance, and poor prognosis, and has yet to be fully investigated in terms of its expression patterns and molecular mechanisms of action in ccRCC.

Purpose: Clear cell renal cell carcinoma (ccRCC) is resistant to radiotherapy and chemotherapy. Thus, it is necessary to find new diagnostic markers and therapeutic targets to increase the overall outcomes of ccRCC. Recent studies have shown that therapeutic methods that interfere with the energy transfer system can also positively affect the treatment process.

To date, pagetoid spread-the proliferation of pagetoid cells in intraepidermal lesions, as observed in secondary extramammary Paget's disease-has not been reported in squamous epithelium derived from the extension of head and neck carcinomas. Herein, we report a case of pagetoid squamous cell proliferation associated with a primary intraosseous carcinoma (PIOC) arising in the periapical lesion of the maxilla, a finding not reported previously. A 60-year-old man presented with prostate adenocarcinoma and bilateral pubic bone, ilium bone, and sacral bone metastases.

Spatial transcriptomics has emerged as a powerful tool for discerning the heterogeneity of the tumour microenvironment across various cancers, including renal cell carcinoma (RCC). Spatial transcriptomics-based studies conducted in clear-cell RCC (the only RCC subtype studied using this technique to date) have given insights into spatial interactions within this disease. These insights include the role of epithelial-to-mesenchymal transitioning, revealing proximity-dependent interactions between tumour cells, fibroblasts, interleukin-2-expressing macrophages and hyalinized regions.

Immune checkpoint inhibitors can lead to 'exceptional', durable responses in a subset of persons. However, the molecular basis of exceptional response (ER) to immunotherapy in metastatic clear cell renal cell carcinoma (mccRCC) has not been well characterized. Here we analyzed pretherapy genomic and transcriptomic data in treatment-naive persons with mccRCC treated with standard-of-care immunotherapies: (1) combination of programmed cell death protein and ligand 1 (PD1/PDL1) and cytotoxic T lymphocyte-associated protein 4 inhibitors (IO/IO) or (2) combination of PD1/PDL1 and vascular endothelial growth factor (VEGF) receptor inhibitors (IO/VEGF).
