Epidermal growth factor receptor (EGFR) genomic alterations are crucial in various cancers. This review examines EGFR alterations as prognostic and predictive factors for targeted cancer therapies.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- The epidermal growth factor receptor (EGFR) plays a significant role in the development and progression of numerous human cancers.
- EGFR is a validated target for antineoplastic therapies, with several EGFR-targeted drugs in clinical use or under investigation.
Purpose of the Study:
- To review preclinical and clinical data on EGFR genomic alterations.
- To evaluate the prognostic and predictive value of these alterations in cancer treatment.
Main Methods:
- Comprehensive literature search for studies on EGFR genomic alterations (mutations, gene copy number).
- Analysis of data regarding EGFR protein expression, gene mutations, and gene copy number.
- Synthesis of preclinical and clinical findings.
Main Results:
- EGFR protein expression data inform the selection of monoclonal antibodies in colorectal cancer.
- EGFR gene mutations guide the use of tyrosine kinase inhibitors in lung cancer.
- EGFR gene copy number is an emerging factor under investigation.
Conclusions:
- EGFR genomic alterations are important prognostic and predictive biomarkers.
- Understanding these alterations is key for optimizing targeted cancer therapy selection and patient outcomes.

Mitogens and the Cell Cycle
Cancer-Critical Genes I: Proto-oncogenes
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.

Tumor Progression
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...
