Influence of Biopsy Technique on Moleculargenetic Tumor Characterisation in NSCLC

2019-06-05 23:47:16 | BioPortfolio


Study design Prospective multicentre explorative randomized single blinded study to evaluate accuracy of molecular genetic characterisation of NSCLC. Patients with suspected lung cancer are randomized in a 1:1-setting for bronchoscopic tumor tissue either by forceps or by cryobiopsy. Apart from the bronchoscopic techniques liquid biopsy of peripheral blood and if feasible transbronchial needle aspiration with or without endobronchial ultrasound guidance are performed for in all patients.


Primary Objective:

assessment of differences in detection of molecular genetic alterations in NSCLC between bronchoscopic forceps biopsy and bronchoscopic cryobiopsy

Secondary Objective:

assessment of differences in detection of molecular genetic alterations in NSCLC between

- liquid biopsy, solid tumor tissue by bronchoscopic techniques, cytologic material by TBNA

- combination of methods (tissue biopsy, TBNA and liquid biopsy) and single techniques

- naïve and processed tumor tissue specimen (eg. microdissection)

To assess differences in side effects e.g. periinterventional bleeding

Explorative Objective:

To explore tumor mutational burden with regard to

- solid tumor tissue by bronchoscopic forceps biopsy by bronchoscopic cryobiopsy

- cytologic material by (EBUS-guided) TBNA

- liquid biopsy

Target subject population Patients with suspected lung cancer or proven NSCLC and visible tumor suspicious lesion(s) requiring tissue diagnosis form the study population of this trial.

Medical and Biotech [MESH] Definitions

Malignant neoplasm arising from the epithelium of the BRONCHI. It represents a large group of epithelial lung malignancies which can be divided into two clinical groups: SMALL CELL LUNG CANCER and NON-SMALL-CELL LUNG CARCINOMA.

A form of highly malignant lung cancer that is composed of small ovoid cells (SMALL CELL CARCINOMA).

A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.

An anaplastic, highly malignant, and usually bronchogenic carcinoma composed of small ovoid cells with scanty neoplasm. It is characterized by a dominant, deeply basophilic nucleus, and absent or indistinct nucleoli. (From Stedman, 25th ed; Holland et al., Cancer Medicine, 3d ed, p1286-7)

A carcinoma discovered by Dr. Margaret R. Lewis of the Wistar Institute in 1951. This tumor originated spontaneously as a carcinoma of the lung of a C57BL mouse. The tumor does not appear to be grossly hemorrhagic and the majority of the tumor tissue is a semifirm homogeneous mass. (From Cancer Chemother Rep 2 1972 Nov;(3)1:325) It is also called 3LL and LLC and is used as a transplantable malignancy.
