How Can We Treat Cancer Disease Not Cancer Cells?

Area of Science:

• Molecular Biology
• Oncology
• Systems Biology

Background:

• Traditional cancer research and drug development focus on molecular differences between cancer and normal cells.
• Despite advances, advanced cancer patients often face poor prognosis and high relapse rates, indicating limitations in current approaches.

Purpose of the Study:

• To highlight the limitations of single-cell-focused cancer research.
• To advocate for a paradigm shift towards understanding cancer as a systemic disease.
• To emphasize the potential of investigating tissue-specific cell networks for novel cancer treatment strategies.

Main Methods:

• This is a review article, synthesizing existing knowledge.
• It analyzes the limitations of current molecular-level cancer research.
• It proposes a systems biology approach focusing on intercellular interactions.

Main Results:

• Current research paradigms targeting cancer cell-specific molecules have yielded limited success in advanced stages.
• Cancer involves complex interactions between tumor cells and their surrounding microenvironment.
• Systemic modulation influences metastasis and disease progression.

Conclusions:

• Viewing cancer as a systemic disease, rather than solely a cellular one, is crucial for progress.
• Investigating tumor-specific cell networks provides a novel perspective for therapeutic development.
• A shift towards understanding tissue-specific cell networks could overcome current treatment limitations.
