EXECUTIVE SUMMARY Patient-derived xenograft (PDX) models are indispensable for translational cancer research. However, public and private PDX tumor banks may lack standard quality controls, which may lead to genomic and transcriptomic...

Overcoming Glioblastoma Multiforme (GBM) Drug Development Challenges With Glioblastoma Xenograft Models Primary brain tumors are highly heterogeneous tumors that cause significant morbidity and mortality. An estimated 700,000 Americans are living...

Colorectal cancer (CRC) is common and deadly, making up an estimated 7.9% of all new cancer cases and 8.7% of all cancer deaths in the U.S. last year.1 Cancer mortality often results from metastasis, which for colorectal cancer, happens frequently; ...

Functional Precision Oncology: Testing Tumors with Drugs to Identify Vulnerabilities and Novel Combinations  

In the past several decades, oncology drug development has had some major successes, from the approval of game-changing therapeutics such as rituximab and trastuzumab in the late-90s to the first tumor-agnostic approval for pembrolizumab in 2017.1...

Why do the quaintest analogies stick to biology’s most morbid phenomena? Look no further than English surgeon Stephen Paget’s “seed and soil” model for breast cancer metastasis for a prototypical example. In his 1889 publication in the Lancet, Paget...

THE RIGHT TUMOR MODELS BRING GREATER CERTAINTY TO DRUG CANDIDATE SELECTION  

FROM GENETIC TESTING FOR CANCER TO FUNCTIONAL, PATIENT-DERIVED MODELS Genetic testing for cancer has rapidly become an important and routine part of oncology treatment. It’s driven the rise of precision oncology, where clinicians seek to match the...

AACR 2021 Poster #2929: Predicting Patient’s Therapeutic Response and Acquired Drug Resistance with Orthotopic Patient-Derived Xenografts (O-PDX) Patient-derived xenografts (PDX) are a commonly used in vivo model that can provide clinically...

Subcutaneous vs Orthotopic Xenografts: Identifying Clinically Relevant Models for Making More Accurate, Personalized Cancer Treatment Decisions In our last blog, we explored some of the current gaps in personalized medicine and how patient-derived...
