Occurrence and Survival Condition of Lung Cancer with Different Histologies 
Among Residents in Pudong New Area

Abstract

Background and objective Different histologies of lung cancer vary in occurrence and prognosis. This study aims to analyze the incidence and occurrence trend of lung cancer and investigate the survival rate and its influential factors among lung cancer patients with different histologies. Methods Permanent residents were recruited between 2002 and 2009 in Pudong New Area (former Nanhui Area and former Pudong Area), Shanghai, China. Annual percent changes were estimated by a linear regression of the logarithm on the incidence rates for eight years. Survival rates were calculated and compared by using life-table analysis and Log-rank test, respectively. Results The standardized incidence rates of lung cancer were 52.28 and 18.86 per 100,000 in males and females, respectively. The median survival time was 410.72 days for specific classified lung cancer. The incidence rates of adenocarcinoma ranked the highest and showed an upward tendency (P<0.05). Patients with small cell lung cancer showed the worst survival condition. The survival condition in males with squamous cell lung cancer living in former Nanhui Area was better compared with those living in former Pudong Area. Conclusion Lung cancers with different histologies demonstrated different occurrence trends and survival rates. Gender, age, and living area influence the survival rates of lung cancer with different histologies.
