Long-term trends of lung cancer incidence and survival in southeastern China, 2011–2020: a population-based study

Abstract

Background Lung cancer is the primary cause of cancer-related deaths in China. This study analysed the incidence and survival trends of lung cancer from 2011 to 2020 in Fujian Province, southeast of China, and provided basis for formulating prevention and treatment strategies. Methods The population-based cancer data was used to analyse the incidence of lung cancer between 2011 and 2020, which were stratified by sex, age and histology. The change of incidence trend was analysed using Joinpoint regression. The relative survival of lung cancer with onset in 2011–2014, 2015–2017 and 2018–2020 were calculated using the cohort, complete and period methods, respectively. Results There were 23,043 patients diagnosed with lung cancer in seven registries between 2011 and 2020, with an age-standardized incidence rate (ASIR) of 37.7/100,000. The males ASIR increased from 51.1/100,000 to 60.5/100,000 with an annual percentage change (APC) of 1.5%. However, females ASIR increased faster than males, with an APC of 5.7% in 2011–2017 and 21.0% in 2017–2020. Compared with 2011, the average onset age of males and females in 2020 was 1.5 years and 5.9 years earlier, respectively. Moreover, the proportion of adenocarcinoma has increased, while squamous cell carcinoma and small cell carcinoma have decreased over the past decade. The 5-year relative survival of lung cancer increased from 13.8 to 23.7%, with a greater average increase in females than males (8.7% and 2.6%). The 5-year relative survival of adenocarcinoma, squamous cell carcinoma and small cell carcinoma reached 47.1%, 18.3% and 6.9% in 2018–2020, respectively. Conclusions The incidence of lung cancer in Fujian Province is on the rise, with a significant rise in adenocarcinoma, a younger age of onset and the possibility of overdiagnosis. Thus, Fujian Province should strengthen the prevention and control of lung cancer, giving more attention to the prevention and treatment of lung cancer in females and young populations.

Complex situations in lung cancer: multifocal disease, oligoprogression and oligorecurrence

“…The treatment landscape of non-small cell lung cancer (NSCLC) is rapidly evolving. Novel treatment compounds and the recent improvements in lung cancer surgery and radiation therapy allow for multimodal treatment approaches and have contributed to the major improvement in survival [ 1 ]. In the past years, the implementation of national lung cancer screening programmes has improved the early detection of pulmonary nodules and comprehensive genomic profiling is providing pivotal information for the assessment of early-stage and advanced-stage NSCLC.…”
