Individualized precision treatment: Targeting TAM in HCC

Area of Science:

• Oncology
• Immunology
• Cancer Biology

Background:

• Hepatocellular carcinoma (HCC) is strongly linked to inflammation, often resulting in poor patient prognosis due to recurrence and metastasis.
• Tumor-associated macrophages (TAMs) are key players in the inflammatory tumor microenvironment, exhibiting M1 and M2 polarization states.

Purpose of the Study:

• To review the multifaceted role of TAMs in influencing hepatocellular carcinoma (HCC) progression.
• To explore how TAM polarization impacts HCC treatment outcomes, including resistance to therapies.
• To provide insights into potential individualized precision therapies for HCC targeting TAMs.

Main Methods:

• Literature review of studies investigating TAMs in HCC.
• Analysis of TAM polarization (M1/M2) and its functional consequences.
• Examination of TAM interactions with other immune cells and their effect on therapy resistance.

Main Results:

• M2-polarized TAMs promote HCC progression by inducing cellular proliferation, angiogenesis, and epithelial-mesenchymal transition (EMT).
• TAMs contribute to therapeutic resistance in HCC by interacting with other immune cell populations.
• TAMs represent a critical factor in the inflammatory microenvironment of HCC.

Conclusions:

• TAMs significantly influence HCC development, metastasis, and therapeutic response.
• Targeting TAM polarization and function presents a promising strategy for novel HCC treatments.
• Individualized monotherapy or combination strategies involving TAM modulation could improve HCC patient outcomes.
