Lymphoma
Interventions
Device: Endobronchial ultrasound guided lymph node sampling
Registration Number
NCT01467635
Lead Sponsor
Royal Brompton & Harefield NHS Foundation Trust
Brief Summary

A prospective diagnostic clinical study randomising patients undergoing endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) of enlarged mediastinal and hilar lymph nodes to have sampling using the usual EBUS-TBNA needle or a novel biopsy forceps (EBUS-TBNB).

The study aims to establish whether the use of EBUS-TBNB can significantly increase the diagnostic yield over EBUS-TBNA, without an increase in complication rates.

Primary Outcome Measures
NameTimeMethod
The percentage of lymph nodes sampled resulting in a definitive diagnosis (as defined in the protocol) in the two study arms.18 months

The definition of a "definitive diagnosis" is dependant on the diagnosis and is clarified below:

* Carcinoma/lymphoma: The lymph node sample is adequate to make a diagnosis as well as provide immunohistochemistry information enabling subtyping of the tumour.

* Sarcoidosis: The presence of well formed epithelioid non-caseating granulomas.

* Mycobacterial infection: The presence of caseating granulomas, positive Ziehl Nielson staining for acid fast bacilli, or the tissue successfully cultures Mycobacterium.

Secondary Outcome Measures
NameTimeMethod
The difference in the complication rate between the two study arms24 months
