Risk Factors for Chemotherapy-Associated Venous Thromboses in Gynaecological Oncology Patients.

Venous thromboses and their consequences are among the main causes of death in patients with tumour diseases. The objective of this study is the analysis of risk factors and the evaluation of the applicability of two risk scores in a purely gynaecological oncology patient collective. The identification of patients at high risk for the occurrence of venous thromboses could enable the implementation of targeted medication-based thrombosis prophylaxis which has a significant benefit and, simultaneously, a low risk.

Evaluation of a novel monoclonal antibody against tumor-associated MUC1 for diagnosis and prognosis of breast cancer.

There is still a great unmet medical need concerning diagnosis and treatment of breast cancer which could be addressed by utilizing specific molecular targets. Tumor-associated MUC1 is expressed on over 90 % of all breast cancer entities and differs strongly from its physiological form on epithelial cells, therefore presenting a unique target for breast cancer diagnosis and antibody-mediated immune therapy. Utilizing an anti-tumor vaccine based on a synthetically prepared glycopeptide, we generated a monoclonal antibody (mAb) GGSK-1/30, selectively recognizing human tumor-associated MUC1.

Atezolizumab for the treatment of triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is associated with poor prognosis and limited treatment options. However, TNBC is known to be more immunogenic compared to other breast cancer subtypes, with tumor-infiltrating lymphocytes playing an important prognostic and predictive role. Furthermore, TNBC has a higher level of programmed cell death-ligand 1 (PD-L1) expression.

Reduced Breast Tumor Growth after Immunization with a Tumor-Restricted MUC1 Glycopeptide Conjugated to Tetanus Toxoid.

Preventive vaccination against tumor-associated endogenous antigens is considered to be an attractive strategy for the induction of a curative immune response concomitant with a long-lasting immunologic memory. The mucin MUC1 is a promising tumor antigen, as its tumor-associated form differs from the glycoprotein form expressed on healthy cells. Due to aberrant glycosylation in tumor cells, the specific peptide epitopes in its backbone are accessible and can be bound by antibodies induced by vaccination.
