Background: Mediastinal nodes metastasis is one of the important factor in determining the action of resections and prognosis. There are various diagnostic procedure in Pulmonology intervention techniques ti diagnose lung cancer, for instance TBNA. The efficacy of this measure has been proven in terms of safety to minimize cost due to precission and accuracy of diagnosis to determine the stage of lung cancer. This study aimed to assess the accuracy of TBNA with FOB in lung cancer patients in Adam Malik general hospital, to describe characteristics of patients, cytology interpretation, technique of TBNA.
Methods: In this descriptive study, we took 20 inpatients eligible in this study in accordance to inclusion criteria (April-July 2014). TBNA were being performed with gauge needle 21-23 to target whenever invovelment of lymph nodes by Thorax CT-scan or the direct visual appear. In addition, general condition of patients, vital signs were being observed while the aspirates examinated by pathologist in the laboratorium.
Results: Most of Patients were among 40-59 years old (n=16; 80.00%), male (n=16; 80.00%), smoker (n=17; 85.00%). Technique of TBNA were jabbing (n=20; 100%), cytology interpretation with C5(adenocarcinoma) (n=8; 40.00%), with sensitivity result 33,3% from this study.
Conclusions: The sensitivity and accuracy of TBNA may vary depending on the study methods, patients population, disease severity, prevalence of mediastinal metastasiss. Other methods can be performed in future studies such as ROSE to increase high sensitivity and accuracy of TBNA. (J Respir Indo. 2016; 36: 28-32)
