Genomically informed cancer therapy requires interpreting tumor and germline DNA. Accessible knowledge bases and clinician education are crucial for implementing precision oncology effectively.
Area of Science:
- Oncology
- Genomics
- Personalized Medicine
Background:
- Advances in molecular oncology and next-generation sequencing enable personalized cancer therapy.
- Interpreting a patient's molecular profile, including tumor and germline DNA, is essential for genomically informed treatment.
Purpose of the Study:
- To review data and tools for precision oncology.
- To present a framework for evaluating the therapeutic implications of genomic alterations.
- To highlight the need for updated knowledge bases and clinician education.
Main Methods:
- Review of existing data and tools in precision oncology.
- Framework development for literature review on genomic alterations and therapeutic implications.
- Curation of genomic alterations to distinguish drivers from passengers.
Main Results:
- Few genomic alterations currently have strong evidence linking them to specific therapies and cancer types.
- Clinical data for many genomic alterations are insufficient for routine biomarker-based therapy.
- There is significant interest in matching patients to early-phase clinical trials based on genomic profiles.
Conclusions:
- Accessible, comprehensive, and updated knowledge bases are needed to support genomically informed cancer therapy.
- Continued education for clinicians and patients is vital for the successful implementation of precision oncology.
- Distinguishing actionable genomic alterations requires careful curation and evaluation of evidence.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
