Autonomic nervous system and cancer

Area of Science:

• Neuroscience
• Oncology
• Physiology

Background:

• The autonomic nervous system (ANS) is crucial for maintaining bodily homeostasis.
• Cancer and its treatments can disrupt the normal function of the ANS.
• Understanding these disruptions is vital for patient care and management.

Purpose of the Study:

• To classify and review the complications of the autonomic nervous system (ANS) in cancer patients.
• To explore the direct and indirect effects of cancer and its therapies on the ANS.
• To examine the molecular interactions between the ANS and cancer.

Main Methods:

• Literature review and synthesis of existing research on ANS dysfunction in cancer.
• Classification of ANS complications into direct (tumors) and indirect (treatment-related, paraneoplastic syndromes) categories.
• Analysis of molecular mechanisms linking the ANS to cancer cells and the tumor microenvironment.

Main Results:

• Direct ANS complications include primary tumors (pheochromocytoma, neuroblastoma) and autonomic symptoms from brain tumors/metastases.
• Indirect ANS complications encompass autonomic dysfunction from chemotherapy, radiotherapy, surgery, and paraneoplastic syndromes.
• Molecular crosstalk between the ANS and cancer cells/microenvironment was reviewed.

Conclusions:

• Cancer and its treatments pose significant threats to autonomic nervous system function.
• A clear classification of ANS complications aids in diagnosis and management.
• Further research into the ANS-cancer molecular interplay may reveal novel therapeutic targets.
