P3.05-010 - Incidence and Survival of Lung Cancer at Oncosalud: Dynamic Cohort Study (ID 2802)
09:30 - 09:30 | Author(s): G. Sarria
- Abstract
Background:
Lung cancer is the most common malignancy in many countries and regions; it represents the first cause of death in the world and the fourth cause of death in the Peruvian population. The incidence of lung cancer in a population affiliated with a prepaid system is important for the implementation of prevention programs. The arm of study was to determinate the incidence rate of lung cancer in a population of affiliates and the survival rate of patients treated in a private institution (ONCOSALUD - AUNA).
Methods:
In a study of dynamic cohort, the incidence of lung cancer was evaluated in a population of affiliates to ONCOSALUD - AUNA between 2008–2013 (n = 1’096,140). Overall survival (OS) was evaluated in patients treated in ONCOSALUD - AUNA between 2000-2005 (n = 241). The incidence rate was calculated based on new cases/persons-year of observation. The OS was calculated according to Kaplan-Meier method.
Results:
The median age was 33 years and 55.7% were women. A total of 2'611,438.3 persons-year of observation was produced and 394 affiliates were diagnosed with lung cancer. The median age at diagnosis was 70 years. The standardized incidence rate by age was 7.9 per 100,000 persons-year (6.5 and 10.0 in women and men per 100,000 persons-year, respectively) and 74 years cumulative risk was 1.0% (0.8 and 1.2% in women and men, respectively). For survival assessment, the median age was 69 years, 39.4% were women and 76.4% had advanced disease (CS III: 18.3% and CS IV: 58.1%). With a 10.6 years follow-up, the median survival was 7.5 months. The OS rate at 2, 5 and 10-years was 24.3%, 16.4% and 12.9%, not showing significant difference in relation to sex (p=0.687), age (<60 vs. > 60 years: p=0.116) and shows significant difference according clinical stage (CS I-II vs. III-IV: p <0.001).
Conclusion:
The incidence rate of lung cancer in our population is lower than reported by the IARC for the Peruvian population. The survival rate at 2, 5 and 10-years is similar to reported for other series.
