Lung Adenocarcinoma : PTEN Mutation Analysis

Test Information

Alterations in PTEN often result in PTEN inactivation and thus increased activity of the PI3K-AKT pathway in neoplastic specimens.

Clinical Information

PTEN mutations have been found in 4�8% of all NSCLC and more commonly in smokers and in tumors with squamous cell histology. Somatic mutations of PTEN have been reported in multiple malignancies, including gliomas, melanoma, prostate, endometrial, breast, ovarian, renal, and lung cancers (Lovly, C., L. Horn, W. Pao. 2015. PTEN in Non-Small Cell Lung Cancer (NSCLC). My Cancer Genome (Updated June 18).). Identification of PTEN mutations can significantly affect the management of lung cancer patients by allowing them an opportunity to be enrolled in open clinical trials (


Gene sequencing and targeted mutation testing and copy number analysis can serve as a useful diagnostic and potentially prognostic tool for the analysis of affected tissues or tumors. The detection of copy number variants or specific gene mutations may enhance treatment decisions.

Specimen Requirements

Analysis can be performed on fresh or frozen tissue samples as well as formalin-fixed, paraffin-embedded tissue samples.

Transport Instructions

The specimen should be kept at the appropriate temperature and delivered via overnight shipping.

One Mother's Story

One Mother's Story

After a long three-year struggle trying to have children, our son, Charlie, was born on April 18, 2009. He was our miracle...perfect in every way! When Charlie was five days old, our pediatrician called to notify us that one of the numbers from the heel prick test was a bit high. We headed to the hospital that afternoon for more tests. I will never forget the following day. It was cool and crisp - not a cloud in the sky....
