Abstract:
Laryngeal carcinoma is the most common site of malignancy in head and neck region worldwide. Surgical options are limited in cases of laryngeal malignancy and moajority of cases are treated with chemoradiotherapy. Targeted therapy is an evolving novel approach to treat laryngeal carcinoma. The study was conducted to evaluate the role of PTEN, EGF and HER2 in early glottic squamous cell carcinoma cases. 52 samples of early glottis carcoinoma were collected in UCMS and GTB hospital, New Delhi after patients had undergone CO2 laser excision at the centre. Histopathologic and IHC examination was conducted on the specimen for PTEN, EGFR and HER2 molecules. PTEN was negative in 82.69% cases compared to the stroma with three year local control rate of 72.09%. EGFR was positive in 67.31% samples with three year local control rate of 68.57%. HER2 was negative in all the samples. PTEN and EGFR can be used as prognostic markers as well as novel agents for targeted therapy in the future.
Insights
This study investigated PTEN and EGFR in early glottic squamous cell carcinoma. Results suggest PTEN and EGFR may serve as prognostic markers and targets for future laryngeal cancer therapies.
Area of Science:
- Oncology
- Molecular Biology
- Head and Neck Cancer Research
Background:
- Laryngeal carcinoma is a prevalent head and neck malignancy with limited surgical options, often managed with chemoradiotherapy.
- Targeted therapy presents a promising novel approach for treating laryngeal cancer.
- Understanding molecular markers is crucial for improving treatment strategies.
Purpose of the Study:
- To evaluate the role of Phosphatase and Tensin homolog (PTEN), Epidermal Growth Factor Receptor (EGFR), and Human Epidermal growth factor Receptor 2 (HER2) in early glottic squamous cell carcinoma.
- To assess the potential of these molecules as prognostic markers and therapeutic targets.
Main Methods:
- Histopathologic and immunohistochemical (IHC) examination of 52 early glottic squamous cell carcinoma samples.
- Analysis of PTEN, EGFR, and HER2 expression in tumor tissues.
- Correlation of marker expression with three-year local control rates.
Main Results:
- PTEN was negative in 82.69% of cases, associated with a 72.09% three-year local control rate.
- EGFR was positive in 67.31% of samples, with a 68.57% three-year local control rate.
- HER2 expression was negative in all analyzed samples.
Conclusions:
- PTEN and EGFR expression levels show potential as prognostic indicators in early glottic squamous cell carcinoma.
- These molecules may represent viable targets for future targeted therapy strategies in laryngeal cancer treatment.

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.
