Clinical Trial Summary

This is a single center, clinical trial evaluating the relevance of intratumoral washing for detection of generic alteration with Next Generation Sequencing.

Description:

This is a prospective, single-arm, open-label study to assess evaluate the relevance of intratumoral washing by ultrathin bronchoscopy (outer diameter; 3mm) for detection of genetic alterations using Next Generation Sequencing in patients suspicious of early-stage lung cancer.

Eligibility

Inclusion Criteria:

Age = 20 years Obtained written informed consent Subjects suspected with resectable lung cancer and planning to undergo bronchoscopy Subjects with no contraindication to brochoscopy Subjects planning to undergo surgery for suspected lung cancer and opting for tissue or liquid biopsy for genetic alteration using Next Generation Sequencing Exclusion Criteria: Patients who withdraw informed consent Patients who are unable to undergo liquid biopsy (plasma) and tissue biopsy for genetic alteration with Next Generation Sequencing based on the investigator's judgement

• Lung Neoplasms

Intervention

Diagnostic Test:
• Ultarthin bronchoscopy with intratumoral washing
Each subject suspected of early-stage, resectable lung cancer will undergo bronchooscopic procedure. Ultrathin bronchoscope is inserted and placed within tumor under radial EBUS, virtual bronchoscopic navigation, and fluoroscopy guidance. Subsequently, intratumoral washing is performed. After undergoing surgery for suspected early-stage lung cancer, the analysis of next generation sequencing is conducted on intratumoral washing, tissue from surgical specimen, and blood.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Genetic alteration with Next Generation Sequencing detection rate in intratumoral washing fluid	Detection rate is defined as the number of genetic alteration with Next Generation Sequencing detection divided by the total attempts of intratumoral washing by ultrathin bronchoscopy.	through study completion, an average of 1 year
Secondary	Concordance rate of genetic alteration with Next Generation Sequencing detection rate among intratumoral washing fluid, plasma, and tissue	The concordance rate of genetic alteration with Next Generation Sequencing detection rate in intratumoral washing fluid, compared with plasma and tissue (gold standard).	through study completion, an average of 1 year
Secondary	Turn-around time	The duration between an order request and the task completion in in intratumoral washing fluid compared with plasma and tissue (gold standard).	through study completion, an average of 1 year
Secondary	Genetic alteration with Next Generation Sequencing sensitivity & specificity in intratumoral washing fluid	The sensitivity and specificity of genetic alteration with Next Generation Sequencing in intratumoral washing fluid compared with tissue (gold standard).	through study completion, an average of 1 year
