Introduction:

lung cancer has become a major health problem worldwide. In Cuba, among the neoplasms, this is the first cause in mortality and the second in incidence.

Objective:

to characterize clinically and epidemiologically lung cancer patients treated at “Dr. León Cuervo Rubio” Clinical-Surgical-Teaching Hospital in Pinar del Río.

Methods:

a cross-sectional and descriptive research was carried out from January 1, 2016 to December 31, 2017. The sample consisted of 83 patients with histological diagnosis of lung cancer.

Results:

the age group between 61 and 80 years and male sex predominated (63,85 %). The most frequent risk factor was active smoking with 93,98 %; the clinical presentation was predominantly bronchopneumonia in 49,40 % of patients, while the most frequent anatomical location was the right upper lobe with 44,53 %. The most frequent cytohistological type was epidermoid carcinoma with 37,35 %, at the time of diagnosis 51,81 % of patients were in stage III.

Conclusions:

lung cancer was more frequent in men and into the group between 61 and 80 years. There was a higher representation of heavy smokers. A correlation between the cumulative effect of smoking and the probabilities of developing cancer in smokers was observed, especially in those with the longest addition and in those who smoke the greatest number of packs per year.
