Multi-targeted therapy of cancer by omega-3 fatty acids-an update

Area of Science:

• Oncology
• Nutritional Science
• Biochemistry

Background:

• Dietary omega-3 polyunsaturated fatty acids (PUFA) intake is associated with cancer incidence.
• Extensive basic and clinical research has explored omega-3 PUFA's role in cancer therapy.
• A previous review on omega-3 fatty acids in cancer therapy was published in 2008.

Purpose of the Study:

• To update the understanding of omega-3 PUFA's effectiveness in cancer therapy by summarizing recent clinical trial data.
• To identify clinical trials with promising results regarding omega-3 PUFA interventions.
• To discuss potential mechanisms underlying the observed clinical outcomes.

Main Methods:

• Systematic review and synthesis of clinical trial data on omega-3 PUFA in cancer therapy.
• Analysis of studies focusing on omega-3 PUFA's impact on cancer-associated symptoms.
• Exploration of potential biological mechanisms of action.

Main Results:

• Omega-3 polyunsaturated fatty acids (PUFA) primarily impact cancer-associated symptoms.
• Promising results were observed in managing cachexia, inflammation, neuropathy, and post-operative complications.
• Improvements in patient quality of life were noted in several trials.

Conclusions:

• Omega-3 polyunsaturated fatty acids (PUFA) show potential in managing cancer-related symptoms and improving quality of life.
• Potential mechanisms include the regulation of skeletal muscle protein turnover, inflammatory responses, and neuron survival.
• Further clinical validation is supported by the growing body of evidence.
