Thrombosis is a more common occurrence in cancer patients compared to the general population and is one of the main causes of death in these patients. Low molecular weight heparin (LMWH) has been the recognized standard treatment for more than a decade, both in cancer-related thrombosis and in its prevention. Direct oral anticoagulants (DOACs) are a new option for anticoagulation therapy. Recently published results of large randomized clinical trials have confirmed that DOAC may be a reasonable alternative to LMWH in cancer patients. The following review summarizes the current evidence on the safety and efficacy of DOAC in the treatment and prevention of cancer-related thrombosis. It also draws attention to the limitations of this group of drugs, knowledge of which will facilitate the selection of optimal therapy.

Neoplastic processes are integrally related to disturbances in the mechanisms regulating hemostatic processes. Brain tumors, including gliomas, are neoplasms associated with a significantly increased risk of thromboembolic complications, affecting 20–30% of patients. As gliomas proliferate, they cause damage to the brain tissue and vascular structures, which leads to the release of procoagulant factors into the systemic circulation, and hence systemic activation of the blood coagulation system. Hypercoagulability in cancer patients may be, at least in part, a result of the inadequate activity of coagulation inhibitors. The aim of the study was to evaluate the expression of the inhibitors of the coagulation and fibrinolysis systems (tissue factor pathway inhibitor, TFPI; tissue factor pathway inhibitor-2 TFPI-2; protein C, PC; protein S, PS, thrombomodulin, TM; plasminogen activators inhibitor, PAI-1) in gliomas of varying degrees of malignancy. Immunohistochemical studies were performed on 40 gliomas, namely on 13 lower-grade (G2) gliomas (8 astrocytomas, 5 oligodendrogliomas) and 27 high-grade gliomas (G3–12 anaplastic astrocytomas, 4 anaplastic oligodendrogliomas; G4–11 glioblastomas). A strong expression of TFPI-2, PS, TM, PAI-1 was observed in lower-grade gliomas, while an intensive color immunohistochemical (IHC) reaction for the presence of TFPI antigens was detected in higher-grade gliomas. The presence of PC antigens was found in all gliomas. Prothrombin fragment 1+2 was observed in lower- and higher-grade gliomas reflecting local activation of blood coagulation. Differences in the expression of coagulation/fibrinolysis inhibitors in the tissues of gliomas with varying degrees of malignancy may be indicative of their altered role in gliomas, going beyond that of their functions in the hemostatic system.

The coagulation system is known to play an important role in cancer development and metastasis, but the precise mechanisms by which it does so remain incompletely understood. With this in mind, we provide an updated overview of the effects of TFPI-2, a protease inhibitor, on cancer development and metastasis. TFPI-2 interacts with the thrombin cascade and also employs other mechanisms to suppress cancer growth and dissemination, which include extracellular matrix stabilization, promotion of caspase-mediated cell apoptosis, inhibition of angiogenesis and transduction of intracellular signals. Down-regulation of TFPI-2 expression is well documented in numerous types of neoplasms, mainly via promoter methylation. However, the exact role of TFPI-2 in cancer progression and possible approaches to up-regulate TFPI-2 expression warrant further studies. Strategies to reactivate TFPI-2 may represent a promising direction for future anticancer studies and therapy development.

The implementation of QIs in the pursuit of improving patient outcomes in oncological care has become a primary goal for many countries. The purpose of this cross-sectional review is to present the experiences of several countries that have implemented different strategies in using QIs to assess the quality of cancer care. Countries such as the United States, the United Kingdom, Canada, the Netherlands, Australia, and Israel have been pioneers in integrating QIs into their healthcare systems, which has led to significant improvements in the delivery of care. These indicators help assess adherence to clinical guidelines, timeliness of treatment, safety of practices, and overall patient survival. Data from these countries show that the use of QIs correlates with improved five-year survival rates, earlier diagnosis, better adherence to evidence-based treatment protocols, and increased patient satisfaction. For example, in the Netherlands and Germany, the introduction of quality cancer care programs has led to improved surgical outcomes and overall survival for patients with colorectal cancer. The United Kingdom and Denmark have reported improvements in waiting times for diagnosis and treatment, and in Israel, screening rates for breast and colorectal cancer increased after the introduction of QIs for monitoring these conditions. The current review highlights the fact that countries with robust reporting systems and national cancer registries with high levels of data completeness, such as Denmark, Sweden, and Norway, were able to effectively monitor outcomes and adjust clinical practices accordingly. The findings suggest that implementing QIs in cancer care not only improves clinical outcomes but also promotes accountability and stimulates improved healthcare, ensuring better long-term patient care. This study highlights the value of adopting QIs as a global standard for assessing cancer care.

Brain gliomas are characterized by remarkably intense invasive growth and the ability to create new blood vessels. Angiogenesis is a key process in the progression of these tumors. Coagulation and fibrinolysis factors play a role in promoting angiogenesis. The aim of the study was to evaluate the expression of proangiogenic proteins (VEGF and bFGF) and hemostatic proteins (TF, fibrinogen, fibrin, D-dimers) associated with neoplastic cells and vascular endothelial cells in brain gliomas of various degrees of malignancy. Immunohistochemical tests were performed using the ABC method with the use of mono- and polyclonal antibodies. The obtained results indicated that both neoplastic cells and vascular endothelial cells in gliomas of various degrees of malignancy are characterized by heterogeneous expression of proteins of the hemostatic system and angiogenesis markers. The strongest expression of proangiogenic factors and procoagulant factors was demonstrated in gliomas of higher-grade malignancy.

Cancer pain is a common issue for patients, especially in the advanced stages of cancer, and significantly affects the quality of life (QoL), treatment tolerance, and overall treatment outcomes. Pain may be caused by primary tumors, metastases, or as a consequence of the inflammatory reaction of tissues surrounding the tumor following radiotherapy (RT). Effective pain management is crucial, especially with RT being a key method for alleviating cancer pain, particularly in cases of bone and soft tissue metastases. RT provides relief for 60–80% of patients by reducing tumor size and mitigating associated pain. Radiotherapy itself can also induce pain, especially radiation-induced neuropathic pain, which may require further treatment. Despite these potential side effects, RT remains an essential tool in managing cancer pain, though careful management of its toxicities is necessary to improve patient QoL and survival.
