Inflammation-Induced Tumorigenesis and Metastasis

Area of Science:

• Oncology
• Immunology
• Molecular Biology

Background:

• Inflammation, particularly chronic inflammation, is increasingly recognized as a critical factor in cancer.
• It influences tumor initiation, progression, and metastasis through diverse molecular pathways.
• Inflammation is now considered a hallmark of cancer and a promising therapeutic target.

Purpose of the Study:

• To review recent advances in understanding the molecular mechanisms by which inflammation promotes tumorigenesis.
• To explore how inflammation contributes to cancer metastasis.
• To discuss the role of inflammation in suppressing anti-tumor immunity.

Main Methods:

• This is a review article, synthesizing current research findings.
• It focuses on molecular mechanisms.
• The review covers various solid tumors and hematopoietic malignancies.

Main Results:

• Inflammation promotes tumor initiation and progression via multiple molecular pathways.
• Inflammatory processes actively contribute to cancer cell metastasis.
• Inflammation can suppress the host's immune response against tumors.

Conclusions:

• Understanding the molecular links between inflammation and cancer is crucial for developing novel therapeutic strategies.
• Targeting inflammation holds significant promise for cancer treatment and prevention.
• This review highlights key mechanisms across various cancer types, including esophageal, gastric, colorectal, liver, pancreatic, and hematopoietic malignancies.
