British Journal of Cancer
|January 10, 2013
Summary
Intra-tumour heterogeneity, distinct genomic alterations within tumors, impacts cancer therapeutics and clinical outcomes. Advanced sequencing and trial designs are key to understanding and managing this complexity.
Area of Science:
- Genomics
- Oncology
- Cancer Biology
Background:
- Malignant tumors exhibit significant genetic complexity.
- Solid tumors contain subpopulations with distinct genomic alterations, known as intra-tumour heterogeneity (ITH).
- ITH has implications for cancer therapeutics and biomarker discovery, especially with targeted treatments.
Purpose of the Study:
- To review current evidence on intra-tumour heterogeneity.
- To discuss the relevance of ITH to cancer therapeutics.
- To explore factors exacerbating ITH and future research directions.
Main Methods:
- Review of existing scientific literature on intra-tumour heterogeneity.
- Analysis of the impact of genomic alterations on tumor subpopulations.
- Discussion of advanced sequencing technologies and clinical trial designs.
Main Results:
- Emerging evidence links intra-tumoural heterogeneity to clinical outcomes.
- Understanding ITH is crucial for effective targeted cancer therapy.
- Advanced sequencing technologies are enhancing the study of ITH.
Conclusions:
- Intra-tumour heterogeneity is a critical factor in cancer progression and treatment response.
- Further research into the drivers of ITH and its clinical relevance is warranted.
- Adapting clinical trial designs and utilizing advanced sequencing are essential for future progress.

Targeted 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.

Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Cancer Stem Cells and Tumor Maintenance
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Treatment Resistant 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...
