Summary
A new method called Oncogramme offers individualized tumor response testing for colon cancer patients. This test shows unique drug responses for each patient, aiding personalized chemotherapy decisions.
Area of Science:
- Oncology
- Cancer Research
- Personalized Medicine
Background:
- Colon cancer is a leading cause of cancer-related death globally.
- Individualized tumor response testing (ITRT) is crucial for tailoring chemotherapy.
- Existing ITRT methods require further validation and optimization.
Purpose of the Study:
- To introduce and validate a novel ITRT method, Oncogramme, for colon cancer.
- To assess the feasibility and reliability of the Oncogramme assay.
- To evaluate the potential of Oncogramme in predicting patient-specific responses to chemotherapy.
Main Methods:
- Colon tumor fragments from patients were dissociated and cultured.
- Isolated tumor cells were treated with chemotherapeutics (alone or in combination).
- Cytotoxicity was measured using a cell death assay to establish the Oncogramme.
Main Results:
- The Oncogramme method demonstrated high cell viability and primary culture success rates.
- Significant inter-patient variability in drug response profiles was observed.
- Intra-patient cell lines showed distinct responses to various chemotherapeutic agents.
Conclusions:
- The Oncogramme is a novel, rapid, and reliable ITRT method for colon cancer.
- The assay provides patient-specific drug response profiles, supporting personalized treatment.
- Further validation through a Phase I clinical trial is recommended for clinical application.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
02:57Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

02:56Treatment Resistent Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
01:21Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
