Targeting Innate Immunity in Breast Cancer Therapy: A Narrative Review

Area of Science:

• Oncology
• Immunology
• Cancer Research

Background:

• Breast cancer was historically viewed as immunologically "cold."
• Emerging research highlights the potential of immunotherapies for breast cancer treatment.
• Both adaptive and innate immunity are crucial for controlling breast cancer growth and metastasis.

Purpose of the Study:

• To review the breast tumor immune microenvironment.
• To discuss innate immune targets and pathways relevant to breast cancer.
• To explore the synergy between innate immunity and adaptive antitumor responses, as well as other therapeutic strategies.

Main Methods:

• Literature review of current research on breast cancer immunology.
• Analysis of innate immune mechanisms and their role in cancer.
• Examination of clinical trials investigating innate immune pathways in breast cancer therapy.

Main Results:

• The breast tumor microenvironment is complex and influences treatment response.
• Innate immune pathways offer promising targets for novel breast cancer therapies.
• Synergistic strategies combining innate and adaptive immunity show potential for enhanced antitumor effects.

Conclusions:

• Activating innate immunity is a promising strategy to overcome the limitations of traditional breast cancer immunotherapies.
• Targeting innate immune pathways can potentially eradicate established tumors and prevent metastasis.
• Further clinical investigation of innate immune-targeting therapies is warranted for breast cancer patients.
