Results of Surgery in Lung Cancer - A Retrospective Study of a Single Center Experience

Surgery provides the best chance for cure in patients with non-small-cell lung cancer stage I or II, but only a small portion of all new cases diagnosed are eventually suitable for surgical resection. Our goal was to appraise the surgical outcomes including survival and progression rates in patientswith histological diagnosis of lung cancer.

Between 1st August 2012 and 30th June 2018, the patients with histological lung cancer diagnosis that underwent surgical resection with a curative intent at the department of Cardiothoracic Surgery of Centro Hospitalar Univer- sitário de São João were included.

The majority of patients were pathological stage I and the most performed surgery was a lobectomy (90.6%). The hospitality mortality was 1,3% and the rate of complication was 26,1%. Patients with forced expiratory volume in 1 second (FEV1) less than 80% had higher (statistically significant difference) frequency of complications. Active smokers, Eastern Co- operative Oncology Group Performance Status (ECOG PS)value different than 0 and FEV1 inferior to 80% had a higher mean length of drainage and higher mean length of stay (statistically significant difference). The overall survival was 92,6% at 1 year, 87,7 % in 2 years and 79,1% in 5 years. The overall survival according to pathological stages were similar when compared with the literature.

Ours results are similar to international centers and we should be more alert to preoperative assessment.
