Novel Detection System for Lung Cancer Curative Effect Monitoring

January 28, 2016 updated by: Jian Zhang

Novel Detection System for Detecting Epidermal Growth Factor Receptor Mutation in Plasma in Non-small Cell Lung Cancer

The purpose of this study is to investigate the sensitivity，specificity and concordance rate of EGFR testing results in plasma in comparison of results in matched tumor tissues tested by amplification refractory mutation system(ARMS). Moreover, the investigators correlate our findings in plasma with survival of advanced patients.

Detailed Description

Non-small cell lung cancer (NSCLC), accounting for 80% of all lung cancers, is a leading cause of cancer deaths worldwide. Inhibition of epidermal growth factor receptor (EGFR) kinase activity by EGFR tyrosine kinase inhibitors, such as gefitinib and erlotinib, can result in improved response and prolonged progression-free survival (PFS) in selected non-small cell lung cancer (NSCLC) patients harboring sensitizing EGFR mutations, especially the exon 19del and exon 21（L858R） mutations. Unfortunately, about 50%-60% patients who accept EGFR tyrosine kinase inhibitors with sensitizing mutations will receive resistance mutations, the T790M resistance is a target of active pharmaceutical development. So EGFR mutation testing is a step in identifying the right patients for EGFR tyrosine kinase inhibitors treatment. Now tissue samples and tumor cytologic samples are accepted as appropriate sample types for EGFR mutation detection, but these samples are not always available on or after diagnosis, and, even when available, they may be of insufficient quality or quantity for mutation testing. Noninvasive techniques for tumor genotyping may be needed to fully realize, such as plasma sample. Cell-free DNA (cf-DNA) in plasma is a kind of fresh and realtime sample, and has been shown to be promising for the detection of sensitizing EGFR mutations even the resistance mutation（T790M). However, a challenge was also raised about how to detect the low abundance of mutant alleles in plasma. In our study Droplet Digital polymerase chain reaction and Realtime polymerase chain reaction will be used to assess the EGFR mutation in plasma DNA samples from patients with advanced NSCLC before and after EGFR tyrosine kinase inhibitors therapy.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
sensitivity
Time Frame: 2 years
comparing with results in tissues, tne investigators can get the sensitivity of results in plasma for Epidermal Growth Factor Receptor mutation in Non-small cell lung cancer.
2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
