| Objective: To investigate the differences and trends of population sociology,clinical and pathological characteristics,and imaging characteristics of patients who underwent lung cancer surgery,and to provide scientific supports for the early diagnosis and treatment of lung cancer.Methods: The cross-sectional study was based on a large tertiary hospital in Hunan Province.The data of patients underwent lung cancer surgery were retrospectively collected,from 2016 to 2019.The changing trends of actual data were analyzed from 2058 lung cancer surgery patients with complete population sociology,clinical and pathological characteristics,and imaging characteristics in 4 years.And they are divided into groups respectively according to different genders and diagnostic modes to discuss the differences and trends of population sociology,clinical information and imaging characteristics of lung cancer surgery patients.Results:1.A total of 2058 surgical lung cancer patients were included in this research.The number of patients each year increases from 2016 to 2019 and the number is280,376,524 and 878 in every single year,respectively.Adenocarcinoma(68.1%)was the most common pathological type of lung cancer surgery patients.From 2016 to 2019,the proportion of adenocarcinoma increased year by year,from 55.5% to 74.1%.The proportion lung cancer patients in stage IA increased from 38.9% to 62.3%.The proportion of patients undergoing sublobar resection increased from1.8% to 8.6%.Since 2019,the proportion of lymph node sampling has increased.Compared with situations in 2016,in 2019 the detection rate of nodules with a diameter of Less than or equal to 1 cm on preoperative CT was significantly higher(18.2% vs.2.0%),and the detection rate of masses larger than 3 cm in diameter decreased(18.3% vs.34.7%).From 2016 to2019,the proportion of pure ground glass density and partial solid density on CT increased from 2% and 16.6% to 20% and 37.3% respectively,while the proportion of solid density decreased from 81.41% to 42.71%.2.From 2016 to 2019,the ratio of male to female patients changed from 2.54:1 to 1.32:1.The proportion of smokers decreased from 61.8% to44.6%,and almost all female patients did not smoke(smoking rate 3.2%).The number of female non-smoking patients with lung cancer increased significantly from 26.4% to 41.9%.Lobectomy was the main approach in for both genders,and the proportion of sublobar resections was higher in women(6.0% vs.3.8%)and stage 0 and stage I(5.6% vs.1.3%,74.9% vs.56.9%,respectively),and the proportion of preoperative CT lesions in the d≤1cm group(16.7% vs.6.8%),the proportion of pure ground glass density and partial solid density was higher(18.9% vs.7.7%,40.4% vs.21.7%,respectively).3.From 2016 to 2019,the proportion of lung cancer patients in the physical examination group increased from 36.1% to 54.2%,and the proportion of patients with lung cancer detected by CT examination in the physical examination group increased from 82.2% to 96.8%.Compared with the symptom group,the proportion of patients in stage 0 and stage I in the physical examination group was higher(4.0% vs.2.1%,72.0% vs.56.8%,respectively),and the proportion of patients in the physical examination group,which correspond to d≤1cm and 1<d≤2cm was higher(14.5% vs.7.6%,42.5% vs.33.3%).Conclusions: The demographics sociology,clinical and pathological characteristics,and imaging characteristics of surgical lung cancer patients are changing.If lung cancer is detected earlier,the surgical method tends to be more minimally invasive.The earlier detections for patients,the less damages for them. |
