New hypotheses for cancer generation and progression.

Area of Science:

• Oncology
• Cancer Biology
• Translational Research

Background:

• Despite significant investment since 1971, cancer research has yielded limited improvements in life expectancy for many cancer types.
• The predominant somatic mutation theory (SMT) may narrow the interpretative scope of carcinogenesis.
• Alternative theories, like the Tissue Organization Field Theory (TOFT), suggest cancer is a tissue disease.

Purpose of the Study:

• To propose novel hypotheses for cancer origin and pathogenesis.
• To discuss the systemic-evolutionary theory of cancer (SETOC).
• To explore the influence of the microenvironment on transformed cell adaptation and phenotypic reversion.

Main Methods:

• Conceptual framework development.
• Theoretical analysis of existing cancer paradigms (SMT, TOFT).
• Exploration of the systemic-evolutionary theory of cancer (SETOC).

Main Results:

• The study introduces the systemic-evolutionary theory of cancer (SETOC) as a new framework.
• It highlights the role of the microenvironment in cancer progression.
• It discusses the potential for transformed cells to revert to unicellular-like or embryo-like phenotypes.

Conclusions:

• Current cancer research paradigms, particularly SMT, may be insufficient for fully understanding carcinogenesis.
• SETOC offers a broader perspective, integrating tissue-level and systemic factors.
• Understanding microenvironmental influences and cellular plasticity is crucial for developing new cancer therapies.
