Abstract

Background: Using the published survival statistics from cancer registration or population-based studies, we aimed to describe the global pattern and trend of lung cancer survival.

Methods: By searching SinoMed, PubMed, Web of Science, EMBASE, and SEER, all survival analyses from cancer registration or population-based studies of lung cancer were collected by the end of November 2022. The survival rates were extracted by sex, period, and country. The observed, relative, and net survival rates of lung cancer were applied to describe the pattern and time changes from the late 1990s to the early 21st century.

Results: Age-standardized 5-year relative/net survival rate of lung cancer was typically low, with 10%-20% for most regions. The highest age-standardized relative/net survival rate was observed in Japan (32.9%, 2010-2014), and the lowest was in India (3.7%, 2010-2014). In most countries, the five-year age-standardized relative/net survival rates of lung cancer were higher in females and younger people. The patients with adenocarcinoma had a better prognosis than other groups. In China, the highest 5-year overall relative/net survival rates were 27.90% and 31.62% in men and women in Jiangyin (2012-2013).

Conclusion: Over the past decades, the prognosis of lung cancer has gradually improved, but significant variations were also observed globally. Worldwide, a better prognosis of lung cancer can be observed in females and younger patients. It is essential to compare and evaluate the histological or stage-specific survival rates of lung cancer between different regions in the future.
