INTRODUCTION : Primary bronchopulmonary cancer (PBC) is the most common
cancer in men. Bronchial fibroscopy occupies a prominent place in the diagnosis of
this cancer although it does not allow histological confirmation in all cases.

Objective: Describe the use of bronchial fibroscopy for the diagnosis of lung cancer.
METHODS : Retrospective study on 54 patients diagnosed with lung cancer in the
pneumology department at the University Hospital of Gabès over a period spanning
from 2020 to 2021.

RESULTS : Our population is composed of 54 of patients. Altogether, 47 patients were
men and 7 women. The median age were 61years, ranging from 31 to 91. The need for
2 or more bronchial fibroscopies was the case in 8 patients (14.3%). This was without
abnormalities in 5 patients (9.25 %), the appearance was strongly suggestive of PBC
(bud, infiltration or stenosis) in patients 66.6%, less suggestive aspects were noted in
13 patients 24 %. The lesions observed were proximal in patients (20.3%). Involvement
of the trachea was noted in 16 patients (24.1%) and of the carina in 5 patients (9.3%).
The cytological study of bronchial fluid was made in 39 patients (73 %). It was
pathological in 22 patients (37.9%) and inconclusive in 17 patients (29.3%). The
diagnosis of PBC was retained on the cytology data of bronchial aspirate fluid in 12
cases. Bronchial biopsies were performed in 48 patients (88.8 %) and allowed the
anatomo-pathological diagnosis in 35 cases. The profitability of this examination is
therefore 71.4 % for all pathological fibroscopies and 98 % when the appearance was
strongly suggestive of cancer.

CONCLUSION : The contribution of bronchial fibroscopy is indisputable in the
establishment of the diagnosis of PBC, however its profitability remains insufficient
with the need for more than two fibroscopies in a quarter of the cases at the origin of
a diagnostic delay.
