Abstract:
Despite advances in understanding cancer at the molecular level, timely and effective translation to clinical application of novel therapeutics in human cancer patients is lacking. Cancer drug failure is often a result of toxicity or inefficacy not predicted by preclinical models, emphasizing the need for alternative animal tumor models with improved biologic relevancy. Companion animals (dogs and cats) provide an opportunity to capitalize on an underutilized and biologically relevant translational research model which allows spontaneous disease modeling of human cancer. Head and neck squamous cell carcinoma (HNSCC) is a common cancer with a poor prognosis and limited clinical advancements in recent years. One potential novel spontaneous animal tumor model is feline oral squamous cell carcinoma (FOSCC). FOSCC and HNSCC share similar etiopathogenesis (tobacco and papillomavirus exposure) and molecular markers (EGFR, VEGF, and p53). Both human and feline SCCs share similar tumor biology, clinical outcome, treatment, and prognosis. Future clinical trials utilizing FOSCC as a tumor model may facilitate translation of preclinical cancer research for human cancer patients.
Insights
Feline oral squamous cell carcinoma (FOSCC) offers a relevant animal model for human head and neck squamous cell carcinoma (HNSCC). This spontaneous model shares similar disease characteristics, potentially improving cancer drug development and clinical translation.
Area of Science:
- Comparative oncology
- Translational cancer research
- Veterinary medicine
Background:
- Translating preclinical cancer research to human clinical application remains challenging due to limitations in current animal models.
- Existing models often fail to predict drug toxicity or efficacy in human cancer patients.
- Spontaneous animal tumor models offer greater biological relevance for studying human cancers.
Purpose of the Study:
- To introduce feline oral squamous cell carcinoma (FOSCC) as a novel and biologically relevant spontaneous tumor model for human head and neck squamous cell carcinoma (HNSCC).
- To highlight the shared etiopathogenesis, molecular markers, and clinical characteristics between FOSCC and HNSCC.
Main Methods:
- Comparative analysis of etiopathogenesis, molecular markers (e.g., EGFR, VEGF, p53), tumor biology, clinical outcomes, treatment, and prognosis between FOSCC and HNSCC.
- Evaluation of FOSCC as a spontaneous disease model for translational cancer research.
Main Results:
- FOSCC and HNSCC share similar risk factors, including tobacco and papillomavirus exposure.
- Key molecular markers such as EGFR, VEGF, and p53 are conserved between feline and human oral cancers.
- Both species exhibit comparable tumor biology, clinical progression, and treatment responses.
Conclusions:
- Feline oral squamous cell carcinoma (FOSCC) represents a promising, naturally occurring animal model for human head and neck squamous cell carcinoma (HNSCC).
- The shared biological and clinical similarities between FOSCC and HNSCC can facilitate the translation of preclinical findings into effective human cancer therapies.
- Utilizing FOSCC in future clinical trials may accelerate the development of novel therapeutics for human cancer patients.
