Prognostic Factors and their Influence of Patients Operated on for Lung Cancer at Hospital Universitario General Calixto García

Abstract

Introduction: Lung cancer ranks first among the causes of cancer mortality worldwide and only 15.6 % of those with this disease survive the 5 years.

Objective: To assess the influence of prognostic factors on the survival of patients operated on for lung cancer.

Methods: A descriptive observational study of case series was carried out with 107 patients operated on at Hospital Universitario General Calixto García in the period 2015-2020. The variables histological type, clinical stage, physical condition and surgical intervention were used.

Results: There was a predominance of the male sex, aged 60-69 years, with a history of arterial hypertension and smoking. The predominant symptoms were dyspnea, cough and chest pain. The most frequent clinical stages were IIIA, IIB, IIA, in that order; and the predominant histopathological variants were adenocarcinoma and epidermoid. The most commonly used surgical technique was lobectomy.

Conclusions: The prognostic factors of greatest statistical significance are comorbidity, presence of symptoms and late diagnosis. Prognostic factors related to the tumor or the adjuvant surgical treatment have a high impact on survival.
