Gastrointestinal cancers create substantial global health burdens as their impact continues to rise in many settings. This cross-sectional study assessed the trend of years of life lost (YLL) attributable to gastrointestinal cancers in Fars Province, southern Iran, over 2004–2019 using population-based death registration data. YLL was computed with the WHO 2015 template and joinpoint regression on a log-linear model evaluated temporal changes. Results quantified total YLL, sex distribution, and cancer-specific patterns.

We aimed to investigate the trend of years of life lost due to gastrointestinal cancers inFars Province, southern Iran during the 2004-2019. Methods: In this cross-sectional survey study, we obtained the information regarding all deaths due to gastro -intestinal cancers in Fars Province from the electronic population-based death registration system (EDRS) .Years of Life Lost (YLL) was calculated using the YLL template of 2015 by the WHO. To examine the trendfor different years, join point regression based on the log-linear model was used. Joinpoint regression analysisdescribes changing trends over successive periods of time and the increasing or decreasing rate within eachperiod. Results: During the years of 2004-2019, 9742 deaths due to gastrointestinal cancers occurred in Fars Prov -ince. 6013 (61.72%) cases were male and 3729 (38.28%) cases were female (Male / Female Sex Ratio: 1.61) .Overall, 4152 cases (42.63%) were due to gastric cancer and 2112 cases (21.68%) were due to liver cancer.Total years of life lost due to premature death from gastrointestinal cancers during the 16-year study periodwas 73565 yr (2.33 per 1000 persons) in men, 52766 yr (1.71 per 1000 persons) in women, and 126331 yr (2.02per 1000 persons) in both sexes. Conclusion: Among all cancers, the highest mortality rates in both sexes belong to gastric cancer. This studyshowed the trend of YLL rate of malignant neoplasms of liver and intrahepatic bile ducts, esophagus, oralcavity, and colon cancer were increasing in both sexes, however, the trend of YLL rate for malignant neo -plasms ofthe small intestine was decreasing in both sexes. Variation of GI cancers patterns and trends aroundthe Fars Province indicated that a more comprehensive control plan is needed to control these variations.
