Problems with DetectingAPC Mutations in Fecal DNA
1. Human DNA small fraction of fecal DNA
2. APC mutations are heterogeneous
3. Mutant APC genes <1% of WT genes
4. Contaminants in feces

“This substantial reduction in national mortality rates has come not from a single research breakthrough but from the careful evaluation and adoption of many interventions, each responsible on its own for only a moderate reduction in breast cancer mortality”

Key Factors Leading to Changes in Management of Breast Cancer
Marked increase in understanding of biology of breast cancer (molecular and cellular biology)
Development of clinical research centers, networks, infrastructure, and methodologies
Improvements and innovations in surgery and radiation therapy
New drugs and combinations: cytotoxic, endocrine, targeted biologic therapies
Patient autonomy Patient advocacy movement

The Future of CancerResearch and Care
Greater emphasis on prevention
Changes in life style – nutrition, exercise,
tobacco, alcohol
Chemoprevention
Screening and early detection
Molecular markers
Molecular imaging
Molecular targeting of cancer as basis of therapy and prevention
![Page 15: Emerging Issues in Cancer Control :](https://reader036.vdocuments.mx/reader036/viewer/2022062423/568145bd550346895db2c65a/html5/thumbnails/15.jpg)
The Future of CancerResearch and Care (cont.)
Multimodality therapy will continue to be central theme
Incremental gains Not simply a biomedical challenge –
Societal imperatives! Integration with State initiatives in
particular the State cancer plan
