P1.01-027 - Increased Risk of Lung Cancer among Women with Superficial TCC: A Potential Risk Cohort for Lung Cancer Screening (ID 5585)
14:30 - 14:30 | Author(s): Y. Tolwin
- Abstract
Background:
Background: Screening for lung cancer is recommended among heavy current or former smokers at age 55-80. Transitional Cell Carcinoma of the Bladder (TCC) and lung cancer share same risk factors, however the existence of TCC is not indicated as a reason for screening for lung cancer. Patients with invasive TCC undergo full staging and therefore lung cancer is usually detected if it co-exists. However, in superficial TCC, lung evaluation is not routinely done and may be missed. Here, we have studied the incidence of lung cancer among low stage bladder cancer patients aiming to evaluate if this can be defined as a population at risk.
Methods:
Methods: The SEER (Statistics, Epidemiology and End Results) database was used to determine the Incidence and standardized incidence ratio (SIR), and the average time to discovery of lung cancer in Patients with localized TCC of the bladder (AJCC 6 stages T~0~ through T~1a2~) in years 2000-2013, stratified by age and gender, and compare them to the SIR for all solid tumors.
Results:
Results: based on 89691 patients (F:M ratio 1:3.3), the SIR for all solid tumors was 1.95[CI95%:1.87-2.04] for women and 1.87[1.83-1.9] for men. The SIR for lung cancer in women was significantly higher, 2.40[2.19-2.62], with significance persisting among all age groups >50y. The SIR for men was 1.81[1.73-1.9], not significantly different from the risk for all solid tumors in any age group. The median latency period until discovery of lung cancer was 5.41, 3.54, 2.74 and 0.08 years in women, and 4.41, 3.59, 2.96 and 0.96 in men, for age groups 50-59, 60-69, 70-79 and 80+, respectively.
Conclusion:
Conclusion: Incidence of lung cancer is higher in localized TCC patients than among the general population, and among women it appears to be significantly higher than the general risk of solid tumors. Early stage TCC patients may therefore stand to gain from lung cancer screening, and should be considered as potential screening candidates.
