Understanding cancer metastasis, the spread of tumors, is crucial for improving patient outcomes. This review examines various animal models used to study metastasis, highlighting their strengths and limitations.

Area of Science:

  • Oncology
  • Cancer Biology
  • Translational Research

Background:

  • Metastasis, the spread of cancer, presents a major challenge in oncology, leading to poor prognoses for affected patients.
  • A deeper understanding of metastatic biology is essential for developing effective treatments.

Purpose of the Study:

  • To review and compare the strengths and weaknesses of various in vivo models used for studying cancer metastasis.
  • To guide the selection of appropriate models for specific research questions in metastasis.

Main Methods:

  • The review summarizes data from existing literature on in vivo metastasis models.
  • Models discussed include transplantable syngeneic mouse models, human-mouse xenografts, genetically engineered mice, and naturally occurring cancers in companion animals.

Main Results:

  • Each animal model possesses unique advantages and disadvantages for studying different aspects of metastasis.
  • No single model is adequate for all research purposes; model selection must be tailored to the specific biological or translational question.

Conclusions:

  • In vivo animal models are indispensable tools for dissecting the complex biology of metastasis.
  • Careful selection of the most suitable metastasis model is critical for advancing cancer research and improving patient outcomes.
