Background: In addition to erectile dysfunction, urinary incontinence is the most common functional limitation after radical prostatectomy (RPE) for prostate cancer (PCa). The German S3 guideline recommends informing patients about possible effects of the therapy options, including incontinence. However, only little data on continence from routine care in German-speaking countries after RPE are currently available, which makes it difficult to inform patients.

Background: To evaluate medication-related risks in older patients with cancer and their association with severe toxicity during antineoplastic therapy.

Methods: This is a secondary analysis of two prospective, single-center observational studies which included patients ≥ 70 years with cancer. The patients' medication lists were investigated regarding possible risks: polymedication (defined as the use of ≥ 5 drugs), potentially inappropriate medication (PIM), and relevant potential drug-drug interactions (rPDDI).

Interactions between U2AF homology motifs (UHMs) and U2AF ligand motifs (ULMs) play a crucial role in early spliceosome assembly in eukaryotic gene regulation. UHM-ULM interactions mediate heterodimerization of the constitutive splicing factors U2AF65 and U2AF35 and between other splicing factors that regulate spliceosome assembly at the 3' splice site, where UHM domains of alternative splicing factors, such as SPF45 and PUF60, contribute to alternative splicing regulation. Here, we performed high-throughput screening using fluorescence polarization assays with hit validation by NMR and identified phenothiazines as general inhibitors of UHM-ULM interactions.

Objectives: To compare the CARG (Cancer and Aging Research Group) and CRASH (Chemotherapy Risk Assessment Scale for High-Age Patients) score regarding the predictive performance for severe toxicity in older patients with cancer.

Methods: We recruited patients ≥70 years and applied the CARG and CRASH score before the start of systemic cancer treatment. The CARG predicts severe overall toxicity; the CRASH additionally predicts hematologic and nonhematologic toxicity.

Neurological disorders can occur before the diagnosis of a malignoma is set. These disorders are induced by a misguided immune response with antibodies against intracellular or cell surface antigens. One of the most common paraneoplastic diseases is the subacute degeneration of the cerebellum.
