Are Aspects of Integrative Concepts Helpful to Improve Pancreatic Cancer Therapy?

SIMPLE SUMMARY: Pancreatic carcinoma is one of the malignancies with the highest cancer-specific mortality. While invading the microenvironment and the dense stroma, the immune system plays a key role in the pathological development, as well as in the treatment of pancreatic tumors. In this review, evidence-based treatment options, including standard oncological treatment and integrative therapies, such as hyperthermia, electroporation, intra-tumoral injections, phytochemical preparations or vitamins to improve the prognosis of patients with pancreatic cancer, are presented and discussed. ABSTRACT: Numerous clinical studies have been conducted to improve the outcomes of patients suffering from pancreatic cancer. Different approaches using targeted therapeutic strategies and precision medicine methods have been investigated, and synergies and further therapeutic advances may be achieved through combinations with integrative methods. For pancreatic tumors, a particular challenge is the presence of a microenvironment and a dense stroma, which is both a physical barrier to drug penetration and a complex entity being controlled by the immune system. Therefore, the state of immunological tolerance in the tumor microenvironment must be overcome, which is a considerable challenge. Integrative approaches, such as hyperthermia, percutaneous irreversible electroporation, intra-tumoral injections, phytotherapeutics, or vitamins, in combination with standard-oncological therapies, may potentially contribute to the control of pancreatic cancer. The combined application of standard-oncological and integrative methods is currently being studied in ongoing clinical trials. An actual overview is given here.
