Drug sensitivity testing utilizing tumor organoids represents a paradigm shift in preclinical oncology research. This approach involves exposing tumor organoids to various therapeutic compounds, including chemotherapy, targeted agents, immunotherapy combinations, or novel drug candidates, and quantitatively assessing subsequent responses such as cell viability, apoptosis, and organoid integrity. By bridging the gap between traditional 2D cell lines and in vivo models, organoid-based testing provides a high-fidelity, scalable system for evaluating therapeutic efficacy and resistance mechanisms in a predictive manner.
High Physiological Relevance
Maintain the original tumor's architecture, cell-cell interactions, and stem cell hierarchy, leading to more predictive drug response data compared to conventional 2D cultures.
Preservation of Tumor Heterogeneity
Capture and sustain the genetic and phenotypic diversity of the parental tumor, including subpopulations with differential drug sensitivities, crucial for understanding and overcoming resistance.
Scalability and Throughput
Enable medium- to high-throughput screening of single agents or combination therapies on a biologically relevant platform, facilitating robust statistical analysis.
Biobanking Potential
Organoids can be reliably expanded and cryopreserved, enabling the creation of living biobanks for retrospective studies, cohort screening, and monitoring resistance evolution.
Treatment-sensitive tumor organoids serve as versatile tools across multiple domains of cancer research and development. Their primary applications include guiding customized therapeutic strategies, identifying biomarkers of response and resistance, screening and validating novel anti-cancer compounds, and elucidating underlying mechanisms of drug action.
| Types | Therapy | Description |
| Gastrointestinal cancer organoid | Chemotherapy, targeted therapy | Organoid drug sensitivity testing shows an 82% concordance rate with observed individual therapy responses. |
| Lung cancer organoid | Chemotherapy, targeted therapy | Organoid drug sensitivity testing demonstrates a predictive capacity with 84.0% sensitivity and 82.8% specificity against individual-derived response data. |
| Breast cancer organoid | Chemotherapy, targeted therapy, immunotherapy | Organoid drug sensitivity testing yields a predictive profile of 82.35% sensitivity, 69.23% specificity, and an overall accuracy of 76.67% in matched analyses. |
| Pancreatic ductal adenocarcinoma organoid | Chemotherapy | Organoid drug sensitivity testing responses show no statistically significant difference from the corresponding individual tumor responses. |

Establishing tumor organoid co-cultures with components of the tumor microenvironment (e.g., cancer-associated fibroblasts, immune cells) for more complex therapeutic modeling.
Alfa Cytology developed a cisplatin-sensitive ovarian cancer organoid model to investigate mechanisms of chemoresistance. This model was established from tumor tissue obtained during the initial surgery of a treatment-naïve, cisplatin-sensitive patient. For comparative analysis, a corresponding resistant model was derived from a patient who had undergone reoperation following the failure of platinum-based chemotherapy. Both organoid lines were stably cultured, and their differential response to cisplatin was rigorously validated over a prolonged treatment period. Subsequent RNA sequencing analysis of the paired models revealed distinct expression profiles of chemosensitivity-associated genes. This comparative study successfully uncovered a novel resistance pathway, demonstrating the utility of our platform in identifying potential therapeutic targets to overcome drug resistance.
