Details and patient eligibility

About

Study participants will be selected from clinical routine patients with endobronchial infiltration of a central lung cancer and indication for bronchoscopic sampling. Consented patients will undergo bronchoscopy for tumor sampling applying two routine sampling methods during one single procedure (EBUS-TBNA and conventional forceps sampling). The sequence of both sampling methods will be randomized in advance. The resulting tissue samples will be analyzed by a pathologist using multiplex PCR and FISH. The corresponding analysis results will be compared between sampling methods. Assignment of a subject to a particular therapeutic strategy is not influenced by this protocol. Medicinal products will be used according to current practice and marketing authorisation.

  1. Informed consent: a signed and dated written informed consent prior to study participation.
  2. Type of subject: inpatient
  3. Age: subjects of more than 18 years and less than 85 years.
  4. Central lesion in computed tomography highly suspicious of lung cancer with clinical indication for further diagnostic applying bronchoscopy.
  5. Central lesion has to be accessible by the biopsy techniques under investigation

Exclusion criteria

Subjects meeting any of the following criteria must not be enrolled in the study:

  1. Females who are pregnant or lactating , who decide not to undergo a bronchoscopy due to the risk for their child
  2. Any contraindication for bronchoscopy and EBUS-TBNA (IBNLT: INR>2, thrombocytopenia <40/nl)
