Pyruvate kinase is one of the glycolytic key enzymes. It exists in various isoforms which are expressed in different cell types. One of these isoforms, the type Tu M2-PK, is strongly overexpressed by tumor cells and released into body fluids. The concentration of Tu M2-PK in body fluids can be quantitatively determined by a commercially available enzyme-linked immunosorbent assay (ELISA)-kit. The Tu M2-PK concentration was measured in EDTA-plasma of 116 patients with renal carcinoma and 42 patients suffering from nephritis, by using this kit. The ranges of the Tu M2-PK-concentrations of the two groups did not overlap, indicating a highly significant discrimination of renal carcinoma and benign renal diseases. Furthermore, the Tu M2-PK concentration in EDTA-plasma correlated strongly with the Robson tumor stage of the 116 patients. The present results indicated that the Tu M2-PK might be the first tumor marker, which could be an excellent complementation of the diagnostic program for renal carcinoma.

Background: Malignant transformation (MT) of mature cystic teratoma (MCT) has a poor prognosis, especially in advanced cases. Concurrent chemoradiotherapy (CCRT) has an inhibitory effect on MT.
Case Summary: Herein, we present a case in which CCRT had a reduction effect preoperatively.

In recent years, the combination of immune checkpoint inhibitors (ICIs) with antiangiogenic agents has led to significant breakthroughs in cancer treatment. Such as programmed cell death 1 (PD-1), programmed cell death ligand 1 (PD-L1), and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). Antiangiogenic therapy plays a pivotal role in normalizing blood vessels and remodeling the tumor immune microenvironment while ICIs not only enhance the host's antitumor immune response by blocking negative regulatory signals but also promote vascular normalization.

Department of Emergency Surgery, Qingdao Eighth People's Hospital, 266000 Qingdao, Shandong, China.
Background: Targeted therapies, including axitinib, a vascular endothelial growth factor receptor inhibitor, and sintilimab, a programmed cell death protein-1 inhibitor, have shown promise in the treatment of advanced renal cell carcinoma (RCC). Although their individual efficacies have been demonstrated, the potential synergistic effects of combining these two agents are still being explored.
Methods: This study retrospectively analysed patients with advanced RCC admitted to our hospital from January 2022 to December 2023.

Background: This study aimed to explore factors affecting adherence to targeted therapy in patients with renal cell carcinoma, focusing on the fear of adverse drug reactions.
Methods: This retrospective case-control study selected patients with renal cancer who received targeted therapy at our hospital from June 2021 to April 2023, categorising them based on their adherence to oral targeted drugs.
Results: Patients with good compliance reported significantly lower levels of fear related to disease progression and adverse drug reactions ( < 0.
