Frequency of EGFR and KRAS Mutations and Clinical-prognostic Correlation in Brazilian Lung Cancer Patients

Lung Neoplasms Clinical Trial

Official title:
Analysis of the Types and Frequency of EGFR and KRAS Mutations and Clinical-prognostic Correlation in Brazilian Lung Cancer Patients at Erasto Gaertner Hospital, Curitiba, Brazil.

Clinical Trial Summary

The assessment of the type and frequency of EGFR and KRAS mutations in lung cancer patients, as well as clinical-prognostic correlation, are crucial in the era of targeted therapies. EGFR-activating mutations predict responsiveness to EGFR tyrosine kinase inhibitors (TKIs) in non-small cell lung cancer (NSCLC) patients and KRAS analysis will be useful in a near future for newest target drugs. In Brazil, few data about the prevalence of EGFR and KRAS mutations is available and their knowledge would allow optimize personalized medicine.

Clinical Trial Description

Assessment of the types and frequency of EGFR and KRAS mutations in NSCLC, as well clinical-prognostic correlations has been extensively studied in many populations. Few Brazilian studies evaluating mutational status in NSCLC has been done so far, none of then explored the regional background nor have considered the quantitative analysis of mutant cell in each sample. Quantitative analysis of the tumor maybe relevant for treatment design for positive samples, p.e a tumor with 90% of mutant clones versus a 15% of mutant clones, which can be obtained currently by the method of pyrosequencing. In this study, investigators will assess EGFR and KRAS status through the pyrosequencing quantitative technique, and will also correlate these with clinical-pathological variables among both adenocarcinoma and squamous cell histological subtypes. So far, no study that have made this correlation is available. ;
