Should sputum ARB evaluation done in patients with squamous cell cancer?

A seventy one year old /man patient was admitted to our hospital with cough, sputum hemoptysis and weight lose that were present for two months. Physical examination revealed bilateral rales. On his chest X-ray caviter lesion with pericavitier infiltration was seen in middle zone. Thorax CT showed the infrahiler mass including irreguler bordered, thick walled cavitier lesion. Bronchoscopic endobronchial biopsy revealed squamous cell cancer and caseifie granulomatous bronchit in the entrance of right lower lobe. Anti-Tbc chemotherapy had been started with four drugs (HREZ) because the sputum ARB results were positive. The patient died because of respiratory failure in fifteenth day of therapy. One month prior to admission of the patient to our hospital, bronchoscopic endobronchial
biopsy that was done in an another center revealed squamous cell cancer and also granulomatous process but despite thus any other diagnostic evaluation (such as sputum ARB) had not been performed. We aimed to notify that sputum ARB evaluation should be done in all patients with pulmonary cavitier lesions for differential diagnosis especially in countries that tuberculous is a common infection like our country.
