Complete pathological response of NSCLC

Methods In a 64y o. male a squamous cell lung cancer was diagnosed in his left upper lobe by bronchoscopic brush biopsy cytology. Stage III.A cT2N2MO. He underwent the neoadjuvant treatment: received six cycles of cisplatin etoposid combination. After the restaging (Stage IBycT2NOMO) we performed a pneumonectomy and the mediastinal blockdissection, because of the involvement of the pulmonary artery and spreading to the lower lobe. The pathologist found only pulmonary fibrosis, but no tumor. In 50 y.o. male an adenocarcinoma of the right upper lobe was diagnosed by bronchoscopic brush cytology. Stage IIIA cT3N2MO. He received the same induction therapy regimen. After restaging (Stage IBycT2NOMO) he underwent a right upper lobectomy. At the operation we have not found any abnormal or enlarged N2 lymphonodes. The hystopathological examination showed only necrotic tissues and haemorrhages, but no tumour. Both patients are alive without any complications and tumourfree.
