An anthracycline-induced cardiomyopathy can already appear at a total cumulative dose of less then 550 mg/m2. Noninvasive cardiological methods have been used in order to detect these fatal side effects early. For cardiological control we applied echo-cardiography with measurements of ventricular size and left ventricular function. 5 out of 39 children who were off anthracycline therapy for 3 months to 8 years showed a decline in left ventricular function, but no clinical symptoms. At present 16 children with anthracycline therapy are controlled by echocardiography. In 2 patients a transient myocardial dysfunction was diagnosed. After stopping anthracycline therapy the left ventricular function improved within 2 to 3 months without specific cardiac treatment.

Targeting uPAR with an antibody-drug conjugate suppresses tumor growth and reshapes the immune landscape in pancreatic cancer models.

Antibody-drug conjugates (ADCs) hold promise to advance targeted therapy of pancreatic ductal adenocarcinoma (PDAC), where the desmoplastic tumor stroma challenges effective treatment. Here, we explored the urokinase plasminogen activator receptor (uPAR) as a candidate ADC target in PDAC, harnessing its massive tumoral and stromal expression in this stroma-dense tumor. We generated a site-specific ADC offering high-affinity, cross-species reactivity, and efficient internalization of the anti-uPAR monoclonal antibody, FL1, carrying a potent anthracycline derivative (PNU-158692).

Purpose: As breast cancer survival rates improve, cardiovascular disease (CVD) has become a critical concern among survivors due to co-morbidities and the cardiotoxic effects of cancer treatments. The risk of developing CVD in this population may surpass the risk of cancer recurrence. This review aims to analyze existing research on the use of statins in breast cancer survivors, focusing on their potential role in mitigating cardiovascular risk and cancer recurrence.

The chemotherapeutic drug doxorubicin (DOX) has been widely used for treating solid tumors attributed to its antiproliferative effectiveness; however, its clinical use is limited due to side effects, including cardiotoxicity, myelosuppression, and drug resistance. Combining DOX with buthionine sulfoximine (BSO), a glutathione (GSH) synthesis inhibitor, showed promising results in overcoming these adverse effects, potentially reducing the required DOX dose while maintaining efficacy. The aim of the present study was to examine the effects of different concentrations of BSO and DOX, both individually and in combination, utilizing B16/F10 (murine melanoma), SNB-19 (human glioblastoma), S180 (murine sarcoma), and SVEC4-10 (murine endothelial) cell lines.

Primary effusion lymphoma (PEL) is an HIV-associated B-cell non-Hodgkin lymphoma (NHL) caused by Kaposi sarcoma herpesvirus (KSHV). There is no validated prognostic model in PEL, and prognosis is thought to be poor compared to other HIV-associated NHL. We derived the PEL-Prognostic score (PEL-PS) from an international real-world training set of 59 patients with HIV-associated PEL who received first-line anthracycline-containing chemotherapy from the HIV and AIDS Malignancy Branch at the National Cancer Institute (NCI) in the United States and the National Center for HIV Malignancy at the Chelsea and Westminster Hospital (CWH) in England from 2000 to 2022.
