The Indian Institute of Technology (IIT) Madras revealed a pioneering cancer genome database. This initiative aims to address the under-representation of Indian cancer data in global studies. With a high incidence of cancer in India, this database will enhance research and facilitate the development of targeted diagnostics and treatments.
Background of the Initiative
The Bharat Cancer Genome Atlas (BCGA) was initiated to fill gaps in understanding the genomic landscape of cancers prevalent in India. Despite the rising cancer incidence, India lacks comprehensive genomic data. This database is crucial for capturing specific genetic variants unique to Indian populations.
Research Achievements
IIT Madras has completed whole exome sequencing on 480 breast cancer patient samples. This research involved collaboration with Karkinos Healthcare and local cancer clinics. The project was part of the Centre of Excellence on Cancer Genomics and Molecular Therapeutics, funded by the Government of India’s “Institutions of Eminence” initiative.
Significance of the Database
The BCGA serves as a compendium of genetic variants in the Indian breast cancer population. It will aid in early diagnostics, understanding disease progression, and improving treatment outcomes. The database is expected to be a vital resource for identifying cancer-specific biomarkers.
Personalised Medicine Approach
The database aligns with the shift towards personalised medicine in India. It aims to integrate genetic and molecular information into clinical decision-making. This approach could enhance the standard of medical care for cancer patients.
Current Cancer Landscape in India
According to the Indian Council of Medical Research, cancer incidence in India has been increasing steadily. Reports indicate that one in nine Indians is likely to develop cancer in their lifetime. The National Cancer Registry Programme marks that over 1.4 million people are currently living with cancer, with a notable annual increase in incidence.
Future Prospects
The BCGA is designed to host data from various researchers working on cancer genomics. This collaborative effort will help identify high-risk groups, monitor cancer progression, and develop personalised treatment strategies. The initiative represents step towards improving cancer care in India.
Collaboration and Data Sharing
The database will accept submissions from researchers across different cancer types. This openness encourages collaboration and enhances the collective understanding of cancer genomics in India. By pooling resources and data, the initiative aims to accelerate advancements in cancer research.
Impact on Healthcare
The establishment of the cancer genome database may transform the biomedical research landscape in India. It holds the potential to shift healthcare towards a more personalised treatment approach, improving outcomes for cancer patients across the country.
Questions for UPSC:

- Point out the implications of increasing cancer incidence in India on public health policy.
- With suitable examples, underline the importance of collaborative research in advancing cancer genomics.
Answer Hints:
1. Critically analyse the role of genetic research in improving cancer treatment strategies in India.
- Genetic research provides vital information about specific genetic variants prevalent in Indian populations.
- It aids in developing targeted therapies and personalized treatment plans based on individual genetic profiles.
- Data from genetic studies can identify biomarkers for early detection and improved diagnostic techniques.
- Research enhances understanding of cancer progression and resistance to treatments, leading to better management strategies.
- Collaborations among institutions strengthen the research framework, ensuring comprehensive data collection and analysis.
2. What is personalised medicine? Estimate its potential impact on cancer care in India.
- Personalised medicine tailors medical treatment to the individual characteristics, needs, and preferences of patients.
- In cancer care, it utilizes genetic and molecular information to select therapies that are most effective for each patient.
- This approach can lead to improved treatment outcomes, reduced side effects, and more efficient healthcare resource use.
- In India, it can address the diverse genetic landscape, enhancing the effectiveness of cancer treatments across different populations.
- Personalised medicine may also encourage advancements in preventive strategies and early interventions, reducing overall cancer burden.
3. Point out the implications of increasing cancer incidence in India on public health policy.
- Rising cancer rates necessitate increased funding for cancer research and healthcare infrastructure.
- Public health policies must focus on early detection and screening programs to reduce mortality rates.
- There is a need for awareness campaigns to educate the public about cancer prevention and risk factors.
- Healthcare systems should integrate genetic research findings into clinical practices for better treatment and management.
- Policies must prioritize equitable access to cancer care and treatment across different regions and demographics in India.
4. With suitable examples, underline the importance of collaborative research in advancing cancer genomics.
- Collaborative research allows pooling of resources, expertise, and data, enhancing the quality of studies (e.g., IIT Madras and Karkinos Healthcare).
- It facilitates multi-institutional projects that can cover a broader demographic, leading to more representative data (e.g., Bharat Cancer Genome Atlas).
- Sharing findings among researchers accelerates the discovery of biomarkers and treatment strategies (e.g., joint publications and conferences).
- Collaboration can lead to the development of standardized protocols for data collection and analysis, improving reproducibility.
- Examples like the Cancer Genome Atlas in the US demonstrate how collaborative efforts can advance cancer research and treatment.
