Background Nasopharyngeal carcinoma (NPC) is not common in most parts of the world but is particularly prevalent in southern China. This study analyzed NPC incidence, mortality, years of life lost (YLL), and survival rates in Xiamen from 2011 to 2020. Methods This study mainly utilized data from the Xiamen City Cancer Registry, and cancer follow-up cohort, covering the period from 2011 to 2020. Crude and age-standardized incidence, mortality, YLL, and survival rates, as well as their trends were analyzed using annual percent change (APC) and average annual percent change (AAPC), stratified by sex and residency status. Results From 2011 to 2020, Xiamen reported 996 new NPC cases (733 males, 263 females) and 513 deaths (396 males, 117 females). Age-standardized incidence, mortality, and YLL rates were 3.58/100,000, 1.83/100,000, and 65.10/100,000, respectively. The AAPC in incidence and mortality rates of NPC was − 5.48% (95% CI: −9.25, −1.54, P  < 0.05) and − 0.82% (95% CI: −6.01, 4.65, P  > 0.05), respectively. The 5-year age-standardized relative survival rate was 55.98% (95%CI: 52.08, 60.17). Conclusion Over the recent decade, a consistent decline in the incidence of NPC has been observed, accompanied an insignificant decreasing mortality trend in Xiamen. Future efforts could focus on enhancing prevention, screening, and treatment strategies to potentially reinforcing these positive trends.

Introduction Currently, nearly one-third of newly diagnosed Colorectal cancer (CRC) cases and associated deaths worldwide are from China. Among Chinese provinces, Fujian exhibited the highest CRC mortality rate. This study aims to analyze long-term trends of CRC epidemiology in Xiamen, Fujian, China. Methods Data were obtained from various cancer surveillance systems, including the Xiamen Cancer Register system, the Xiamen Death Register system, and the household registration system. Trends in incidence, mortality and survival rates from 2011 to 2020 were analyzed using annual percent changes (APC) and average annual percent changes (AAPC), stratified by sex and residency status. Results A total of 7,406 new cases and 3,726 CRC-related deaths were reported from Xiamen. The age-standardized of incidence and mortality rates were 26.09 per 100,000 and 12.70 per 100,000, respectively. The observed 5-year survival rate was 46.65%, with an age-standardized survival of 51.24%. CRC incidence in Xiamen is significantly increasing (AAPC = 4.90%). In contrast, trends in CRC mortality and survival rates are not significant. Urban areas exhibited higher rates of CRC incidence, mortality, and survival rate compared to rural areas, though rural areas showed a more marked upward trend. Conclusions The burden of CRC in Xiamen is notably high, with a concerning increasing in incidence. This underscores the urgent need for targeted strategies to address this public health challenges.

Gastric cancer remains one of the most common cancers and the leading cause of death in China. This study aims to describe the incidence, mortality, survival rates, and their changing trends of gastric cancer in Xiamen, China from 2011 to 2020. Population-based cancer registry data were used to calculate the incidence, mortality, and survival rates of gastric cancer. The study population consisted of gastric cancer patients diagnosed from January 1, 2011, to December 31, 2020, and followed up until September 30, 2023. The relative survival of gastric cancer was calculated using period methods. The change in trends was analyzed using Joinpoint regression. From 2011–2020, a total of 4716 new cases of gastric cancer and 3520 related deaths were reported. The crude incidence rate and age-standardized incidence rate (ASIR) were 21.82/100,000 and 16.74/100,000. The crude mortality rate and age-standardized mortality rate (ASMR) were 16.29/100,000 and 12.30/100,000. The ASIR and ASMR in males (ASIR: 24.71/100,000, ASMR: 18.75/100,000) were both more than those in females (ASIR: 9.6/100,000, ASMR: 6.55/100,000). The observed 5-year survival rate was 25.83 %, with an age standardized survival of 27.60 %. The incidence and mortality of gastric cancer showed a decreasing trend, and the 5-year ARS between 2016 and 2020 (30.03 %, 95 %CI: 28.07–32.12 %) was higher than between 2011 and 2015 ( 24.79 %, 95 %CI: 22.53–27.27 %). Furthermore, the survival rate decreased with increasing age. From 2011–2020, the incidence and mortality of gastric cancer in Xiamen City have shown a decreasing trend, and the survival rate has significantly improved. Despite improved survival, the 5-year ARS remains low. •Declining Incidence Rate: Decreasing gastric cancer incidence trend highlighting prevention effectiveness.•Declining Mortality Rate: Reduction in gastric cancer mortality partly due to improved prognosis.•Improved Survival Rate: Despite improved survival, the 5-year ARS remains low, indicating the need for further efforts.•Age as a Prognostic Factor: Enhance gastric cancer screening for high-risk populations, particularly the elderly.

To analyze the trends of lung cancer incidence and mortality in Xiamen from 2011 to 2020 and provide some clues for the lung cancer prevention and control. The data was obtained from the Xiamen City Cancer Register in Fujian Province, China. The data was updated on Sep 30, 2023. The codes of C33-C34 were used to identify the lung cancer. The newly diagnosed lung cancer patients during the period of 2011-2020 in Xiamen City were included in the evaluation of incidence and mortality and Cox analysis. A total of 11408 lung cancer patients were enrolled. The crude incidence rate was 52.78 per 100000 and the age-standardized incidence rate (ASIWR) was 40.67 per 100000 from 2011 to 2020. Both the crude incidence rate of lung cancer (AAPC =5.92, value <0.001) and ASIWR (AAPC = 4.93, value <0.001) showed increasing trends. The crude incidence rate in female increased 4.90 times faster as that in male (AAPC: 12.34/2.52). The crude mortality rate and the age-standardized mortality rate (ASMWR) were 37.25 per 100000 and 28.30 per100000. The 5-year age-standardized relative survival rate (ARS) was 18.62% (95% CI: 17.63-19.67%). The 5-year ARS was higher in women than men (26.35% vs 15.28%) and higher in urban than rural areas (21.44% vs 11.96%). Patients with lower education levels had significantly lower ARS than those with higher education (14.66% vs 31.53%). The 5-year ARS improved notably from 2016-2020 compared to 2011-2015 (22.23% vs 13.21%). Farmers had the lowest ARS among occupations [13.34% (95% CI:11.93-14.92%)]. There were all increasing trends in 1-year, 3-year, 5-year, and 10-year ARS rates between 2011 and 2020 (all values of AAPC<0.05). Lung cancer incidence in Xiamen increased, while mortality decreased with improved survival. Developing more perfect need to consider the differences in the social environment and other factors.
