Background:
The operative and conservative results of therapy in pancreatic ductal adenocarcinoma remain appallingly poor. This underlines the demand for further research for effective anticancer drugs. The various animal models remain the essential method for the determination of efficacy of substances during preclinical phase.
Objective:
Unfortunately, most of these tested substances showed a good efficacy in pancreatic carcinoma in the animal model but were not confirmed during the clinical phase.
Methods:
The available literature in PubMed, Medline, Ovid and secondary literature was searched regarding the available animal models for drug testing against pancreatic cancer. The models were analyzed regarding their pros and cons in anticancer drug testing.
Conclusion:
The different modifications of the orthotopic model (especially in mice) seem at present to be the best model for anticancer testing in pancreatic carcinoma. The value of genetically engineered animal model (GEM) and syngeneic models is on debate. A good selection of the model concerning the questions supposed to be clarified may improve the comparability of the results of animal experiments compared to clinical trials.
Insights
Pancreatic cancer drug testing requires better animal models. Orthotopic models in mice show promise for preclinical evaluation of anticancer drugs, improving clinical trial relevance.
Area of Science:
- Oncology
- Preclinical Research
- Drug Development
Background:
- Pancreatic ductal adenocarcinoma (PDAC) therapy yields poor outcomes, necessitating novel anticancer drugs.
- Animal models are crucial for preclinical drug efficacy assessment.
- Many drugs effective in animal models fail in human clinical trials for pancreatic cancer.
Purpose of the Study:
- To review and analyze available animal models for pancreatic cancer drug testing.
- To evaluate the advantages and disadvantages of each model for anticancer drug screening.
Main Methods:
- Comprehensive literature search of PubMed, Medline, and Ovid databases.
- Inclusion of secondary literature on animal models for pancreatic cancer.
- Analysis of identified models based on their suitability for drug testing.
Main Results:
- Orthotopic animal models, particularly in mice, are currently considered the most effective for preclinical pancreatic cancer drug testing.
- The utility of genetically engineered (GEM) and syngeneic models remains under discussion.
- Model selection significantly impacts the translatability of preclinical findings to clinical outcomes.
Conclusions:
- Optimizing animal model selection is critical for enhancing the predictability of preclinical drug testing results.
- Modified orthotopic models in mice offer the most promising platform for evaluating novel pancreatic cancer therapies.
- Further research is needed to refine and validate animal models for more reliable drug development in pancreatic cancer.
