Abstract:
The tumor microenvironment influences cancer progression and response to treatments, which ultimately impacts the survival of patients with cancer. The sympathetic nervous system (SNS) is a core component of solid tumors that arise in the body. In addition to influencing cancer progression, a role for the SNS in the effectiveness of cancer treatments is beginning to emerge. This review explores evidence that the SNS impairs chemotherapy efficacy. We review findings of studies that evaluated the impact of neural ablation on chemotherapy outcomes and discuss plausible mechanisms for the impact of neural signaling on chemotherapy efficacy. We then discuss implications for clinical practice, including opportunities to block neural signaling to improve response to chemotherapy.
Insights
The sympathetic nervous system (SNS) can negatively impact chemotherapy effectiveness in solid tumors. Blocking neural signals may improve patient responses to cancer treatment.
Area of Science:
- Oncology
- Neuroscience
- Cancer Biology
Background:
- The tumor microenvironment significantly affects cancer progression and treatment outcomes.
- The sympathetic nervous system (SNS) is increasingly recognized as a key component within solid tumors.
- Emerging evidence suggests the SNS plays a role in modulating the efficacy of cancer therapies.
Purpose of the Study:
- To review the evidence linking the SNS to impaired chemotherapy efficacy.
- To explore the mechanisms by which neural signaling influences treatment outcomes.
- To discuss clinical implications for targeting the SNS to enhance chemotherapy response.
Main Methods:
- Literature review of studies investigating neural ablation and chemotherapy outcomes.
- Analysis of proposed mechanisms for neural signaling's impact on chemotherapy.
- Discussion of clinical applications for blocking neural pathways.
Main Results:
- Evidence indicates that the SNS can reduce the effectiveness of chemotherapy.
- Studies involving neural ablation show potential improvements in chemotherapy outcomes.
- Plausible mechanisms involve neural signaling pathways affecting cancer cells and treatment response.
Conclusions:
- The sympathetic nervous system (SNS) represents a significant factor in chemotherapy resistance.
- Targeting neural signaling presents a potential strategy to overcome treatment resistance.
- Further research and clinical trials are warranted to explore anti-neural therapies for cancer treatment.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
