Cancer neuroscience: Mechanisms to medicine

Area of Science:

• Oncology
• Neuroscience
• Cancer Biology

Background:

• The nervous system is increasingly recognized as a key factor in cancer biology.
• Neural inputs influence tumor growth in both central nervous system and extracranial tumors via diverse mechanisms.

Purpose of the Study:

• To explore the mechanisms by which neural signaling impacts cancer.
• To discuss the potential of repurposing neuroactive agents for cancer therapy.
• To address the translational challenge of matching neural circuits and neuromodulators with patients for enhanced immunotherapy.

Main Methods:

• Review of existing literature on neuro-cancer interactions.
• Analysis of mechanisms including synaptic signaling, adrenergic regulation, and immune remodeling.
• Examination of clinical trials involving neuroactive agents as cancer therapy adjuncts.

Main Results:

• Neural inputs modulate tumor growth through synaptic, adrenergic, and bioelectric pathways.
• Repurposed neuroactive agents are under investigation in clinical trials.
• Successful translation requires precise patient stratification and combination therapies.

Conclusions:

• The nervous system plays a critical role in cancer progression.
• Neuromodulators combined with immunotherapy offer a novel strategy to restore antitumor immunity.
• Personalized approaches are essential for optimizing neuro-oncology treatments.
