The cancer patient’s own drug sensitivity model

The cancer patient’s own drug sensitivity model: researchers from the Lothe lab and collaborators recently published a paper in Clinical Cancer Research describing ex vivo patient-derived organoids from colorectal liver metastases in a heterogeneity context. 

Drs. Jarle Bruun, Kushtrim Kryeziu and Peter W. Eide (photo) were shared 1st authors , and have established the PDO lineages and drug screen analyses.

The study is a major interdisciplinary work, from the clinical logistics at Rikshospitalet (HPB-surgery team) for optimal lesion-specific biobanking of resected liver metastases, to immediate establishment of tumor-derived organoid cell cultures in the lab, and integrated pharmacological and gene expression profiling. 

This is the first medium-sized study on intra-patient inter-metastatic pharmacotranscriptomic heterogeneity, and the main finding is that distinct lesions from individual patients generally have similar drug sensitivities. The study thus reinforces the potential benefit from off-label use of drugs in colorectal cancer, guided by ex vivo pharmacological profiling”.
