Background: Conventional transbronchial needle aspiration (c-TBNA) is a minimally invasive bronchoscopic technique used to obtain cytological samples from peribronchial lesions and mediastinal lymph nodes. However, the concern about its efficacy and the advent of newer techniques have led to the underutilization of this time tested and cost-effective modality. Objective: The present study was aimed to assess the diagnostic yield of c-TBNA in suspected cases of lung cancer. Method: c-TBNA smears received from January 2017 to February 2020, with clinical-radiological suspicion of lung malignancy were retrospectively analyzed. Result: A total of 22 cases were reviewed. The mean age of the study population was 57.54 years, with a male-female ratio of ~2:1. The adequate aspirate was obtained in 19/22 (86%) cases. The overall diagnostic yield of c-TBNA was 82%. 14/19 (74%) cases were positive for malignancy, non-small cell lung carcinoma being the most common malignancy diagnosed (11 cases). 4/19 (21%) cases were diagnosed with granulomatous pathology, while smears in 1 case were non-diagnostic. Conclusion: Conventional transbronchial needle aspiration cytology is an efficacious method used for the diagnosis of lung carcinoma. Especially in resource-limited settings, it remains irreplaceable as a diagnostic tool and should be routinely utilized.

Background Recent studies suggest a mutual relationship between lung cancer and microbial colonization of the bronchial airways. However, data on this subject is scarce, especially among Egyptian studies. This study aimed to evaluate the rate and type of bronchial colonization in patients with proven lung cancer at the time of diagnosis by bronchoscopy. Fifty patients who fulfilled the study inclusion criteria underwent bronchial wash or bronchoalveolar lavage samples and were subjected to bacteriological culture and susceptibility. Results Bacterial colonization was recorded in 40% of the studied patients, all of which were potentially pathogenic microorganisms (PPMs). All 23 isolated organisms were Gram-negative bacteria of which 39% were multidrug-resistant (MDR). The most common were Pseudomonas aeruginosa 73.9% and Klebsiella spp. 17.4%. Double growth was detected in 15% of cases. Bronchial colonization in lung cancer had a statistically significant relationship with male gender (p = 0.032), old age (p = 0.037), and chronic obstructive pulmonary disease (p = 0.001). The highest antibiotic sensitivity was observed with Imipenem (69.2%), while the highest antibiotic resistance rates were observed with Ampicillin/Sulbactam and Ceftriaxone (100%). Conclusion Gram-negative PPMs were isolated in 40% of lung cancer cases at the time of diagnosis by bronchoscopy with higher frequency among males, old age, and patients with associated COPD. Among isolated organisms, 39% were MDR pathogens.
