MSPM: Molecular Study and Precision Medicine for Colorectal Cancer
Study Details
Study Description
Brief Summary
Researchers collect specimens from advanced or recurrent colorectal cancer (CRC) patients to conduct molecular profiling and establish tumor organoids (PDOs)/ patient-derived xenografts (PDXs). The aim of this study is to identify clinical actionable targets and predict in vivo response of the tumor to targeted drugs by using PDOs/ PDXs. And the above-mentioned studies will provide the patients with potential personalized cancer treatment options.

Detailed Description
Patient-derived organoid is a model that can recapitulate the histology and behavior of the cancer from which it is derived, and is increasingly used as a tool for drug development in pre-clinical settings. Clinical treatment option of colorectal cancer now is quite limited. By molecular profiling, clinical actionable alterations may be identified. And according to the genomic investigation results, we can find the matched targeted drugs, following further testing in the organoids and PDXs. This will provide an opportunity to guide the precision medicine.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Colorectal Cancer Colorectal cancer patients with advanced or recurrent tumors |
Other: Molecular Profiling & drug testing in tumor organoids and PDXs
Molecular profiling of native tumor will be performed and analyzed by using a self-designed panel. Tumor organoids will be cultured from fresh tumor tissues and patient-derived xenografts model will be established using the tumor organoids. Drugs will be tested in the two models. And the recommendation will be communicated to the clinicians.

Outcome Measures
Primary Outcome Measures
- Identification of effective drugs or drug combinations [up to 3 years]
Viability of organoid is measured using CellTiter-Glo by quantifying ATP, which indicates the presence of metabolically active cells.
Secondary Outcome Measures
- Comparison of clinical actionable alterations identified in native tumor and organoids. [Up to 3 years]
Genomic gene mutation numbers are identified using the Next-Generation Sequencing (NGS).
- Correlation between organoid and PDX drug sensitivities [Up to 3 years]
Size of the tumor is measured to reflect the drug response.
