Introduction: Although many studies have reported that upper urinary tract stones in patients with nonfunctioning kidneys are associated with malignancy, the incidence and frequency of the tumor cell type remain unclear. Therefore, we aimed to investigate the percentage of malignancies present in patients with nonfunctional kidneys who underwent nephrectomy.
Materials And Methods: From July 1995 to December 2005, we reviewed a total of 47 patients who underwent nephrectomy to treat a nonfunctional kidney due to urolithiasis with clinical symptoms such as complicated chronic infection. Pathology revealed malignancies in 24 patients. Relationships between clinical presentations and malignancy were analyzed.
Results: Malignancy was diagnosed in 24 patients after nephrectomy. Image studies revealed possible malignancy in only 7 patients before surgery. A high incidence (17/24) of transitional cell carcinoma was noted. The remaining malignancies included 5 renal cell carcinomas, 1 squamous cell carcinoma and 1 epidermoid carcinoma. There were 5 deaths during the follow-up interval.
Conclusions: There is a high incidence of malignancy associated with nonfunctional kidney caused by stone disease. We suggest careful examination of the pathological specimens from nephrectomy for nonfunctional kidney regardless of clinical manifestations.

Objective: The objective of this research was to devise and authenticate a predictive model that employs CT radiomics and deep learning methodologies for the accurate prediction of synchronous distant metastasis (SDM) in clear cell renal cell carcinoma (ccRCC).
Methods: A total of 143 ccRCC patients were included in the training cohort, and 62 ccRCC patients were included in the validation cohort. The CT images from all patients were normalized, and the tumor regions were manually segmented via ITK-SNAP software.
CHAF1B promotes the progression of lung squamous-cell carcinoma by inhibiting SETD7 expression.

The p60 subunit of the chromatin assembly factor-1 complex, that is, chromatin assembly factor-1 subunit B (CHAF1B), is a histone H3/H4 chaperone crucial for the transcriptional regulation of cell differentiation and self-renewal. CHAF1B is overexpressed in several cancers and may represent a potential target for cancer therapy. However, its expression and clinical significance in lung squamous-cell carcinoma (LUSC) remain unclear.

Beyond the more common TFE3 fusion partners PRCC, ASPSCR1, and SFPQ, additional less common fusion partners of TFE3-rearranged renal cell carcinoma (RCC) have been described. Herein, we present an example of TFE3-rearranged renal cell carcinoma harboring fusion partner MAPK1IP1L, a rare rearrangement with only one other reported tumor found in the literature. The currently reported TFE3-rearranged RCC demonstrates unique histological features compared to the previously reported tumor including dense eosinophilic cytoplasm and nuclear pseudoinclusions (corroborated by electron microscopic evaluation), with features not typically seen in other TFE3-rearranged RCCs.

In recent years, the use of cationic peptides as alternative drugs with anticancer activity has received attention. In this study, the targeted release of curcumin (Cur) and CM11 peptide alone and together against hepatocellular carcinoma (HCC) was evaluated using chitosan nanoparticles (CS NPs) coated with Pres1 that target the SB3 antigen of HCC cells (PreS1-Cur-CM11-CS NPs). SB3 protein is the specific antigen of HCC and the PreS1 peptide is a part of the hepatitis B antigen, which can specifically bind to the SB3 protein.

Purpose: Sleep quality contributes to the improvement of quality of life in cancer patients. However, sleep disturbances, of variable and heterogeneous etiologies, are common and frequently overlooked in lung cancer patients. The present study undertakes a rapid review of available peer-reviewed literature on sleep quality in lung cancer patients, specifically non-small-cell lung cancer patients.
