Backgroud: The problem of diagnostic lung tumor is a challenge for clinicians, especially pulmonologists in determining the definitive diagnosis of a lung tumor.Objective: To analyze the suitability of the results of anatomic pathology between Core-Needle Biopsy (CNB) and Fine-Needle Aspirate Biopsy (FNAB) in peripheral lung tumors. Method:The design of this study used a cross-sectional study which was conducted in the period September 2019-December 2020.Participants are examined by CNB and FNAB at one time.Statistical analysis used the Kappa test with p <0.05.Result: Most of the tumor locations were in the superior lobe of the right lung which had FNAB results in the category of malignancy (39.5%), non-malignant (30.0%), and undiagnosed (27.8%; p = 0.306).Meanwhile, in CNB, most of the tumor locations in the superior lobe of the right lung had CNB results in the malignant category (34.4%), non-malignancy (26.7%), and undiagnosed (75.0%; p = 0.240).Comparison of the results of the anatomical pathology from the FNAB and CNB materials in the malignance category as many as 35 participants (74.5%), 7 participants (53.8%) and undiagnosed non-malignancies with 4 participants (16.7%) with an accuracy of 69.69% (Κ = 0.43; p = 0.001 ).Conclusion: There is a sufficient degree of agreement between the anatomical pathology results of the FNAB and CNB materials for the diagnosis of peripheral lung tumors.
