However, few studies have quantified life expectancy (LE) and years of life lost (YLL) among cancer patients, particularly in China. This study aims to estimate LE and YLL by cancer type, sex, age at diagnosis, and attained age (i.e., the age a cancer survivor has reached at a given time) for cancer patients in China.  \nMethods: This is a comparative assessment based on population-based cancer registration and death surveillance in China. Data on all-cause deaths, cancer cases, and relative survival in 2021 were obtained from publicly available reports released by the National Cancer Center and the Chinese Center for Disease Control and Prevention. Life tables for the general population were constructed using age-specific all-cause mortality rates, whereas relative survival ratesand parameterized long-term excess hazard functions were used to construct life tables for cancer patients. We used the standard period life table method to estimate LE of both the general population and cancer patients, assuming that mortality probabilities remained constant over time. The YLL was the LE difference between cancer patients and the sex-and age-matched general population.  \nResults: For cancer patients diagnosed at the median age of 64 years, the LE is 8.8 years [95% confidence interval (CI) 8.7–9.0], corresponding to a YLL of 9.2 years (95% CI 9.0–9.3) . Male patients have an LE and YLL of 6.7 years (95% CI 6.6– 6.8) and 9.8 years (95% CI 9.7–9.9), respectively, while females have 11.2 years (95% CI 11.1–11.4) and 8.4 years (95% CI 8.3–8.6) . Thyroid cancer had the highest LE [31.9 years (95% CI 31.5–32.0)], while pancreatic cancer had the lowest [2.6 years (95% CI 2.4–2.8)] . Female patients had better LEs than males across 20 cancer types that affect both sexes. Younger patients experienced greater YLL, except in cases of thyroid cancer, oropharyngeal cancer, ovarian cancer, and male bladder cancer. LE gradually increased in patients who survived the first three years; thereafter, the decline depended on attained age, approaching that of the general population.  \nConclusions: LE of cancer patients in China varied by sex, cancer type, age at diagnosis, and attained age. Cancer patients, healthcare providers, and policymakers may incorporate these estimates into their decision-making. Key words Cancer, Life expectancy (LE), Years of life lost (YLL), Population-based, China  \nBackground  \nLife expectancy (LE) is a summary measure of mortality that estimates the average number of years a population is expected to live. It is not only widely used in demographic analysis but also serves as a compelling summary measure for public health [1] . Compared to the general population, cancer patients have a higher excess mortality risk and experience a substantial loss of life years. The LE indicator integrates the complete mortality profile of the observed population and is unaffected by the age structure of the population [2]. Therefore, comparing the differences in LE and healthy LE between cancer patients and the general  \n†Chang-Fa Xia and Jing Yang contributed equally to this work  \n*Correspondence: Wan-Qing Chen, [chenwq@cicams.ac.cn](chenwq@cicams.ac.cn)  \n3National Central Cancer Registry, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100021, China  \nFull list of author information is available at the end of the article  \npopulation directly quantifies the true burden of cancer [3].
