Incidence of pancreatic malignancies in the Russian Federation: a retrospective cohort trial

Background. Pancreatic malignancies pose a challenging medical and social problem. The assessment of oncology care requires an in-depth analysis of morbidity and lethality. At a relatively improved prevalence and lethality in other-locale malignancies, pancreatic cancer remains a disappointing situation. Medical statistics in pancreatic malignancy can be used for the specialty care prediction and implementation of measures to advance diagnostic algorithms and population screening.

Objectives. An assessment of the pancreatic malignancy incidence and mortality in the adult population of Russian Federation over a six-year period.

Methods. A retrospective descriptive cohort trial included statistical data on morbidity and mortality in pancreatic cancer patients (C 25.0-C 25.9) according to the ICD of 10th edition. A comparison cohort sampled patients with all-locale neoplasms (C00-C96) according to the ICD of 10^th edition, excluding nosologies C25.0-C25.9. Information was sourced in the Federal Statistical Abstracts for the period of 2014-2019. Inclusion criteria: the study cohort included pancreatic cancer patients diagnosed at the age of 18 years on, and comparison cohort — malignancy patients diagnosed with at 18 years on. The main study indicator were the pancreatic cancer morbidity and mortality figures in Russia.

Results. Pancreatic cancer was shown to co-increase main morbidity figures in 2014-2019 compared to malignant neoplasms of other localities. Other-locale malignancies decreased mortality over the study period, which was not the case with pancreatic cancer. The period exhibits more frequent morphologically verified diagnoses and higher population numbers registered with specialty dispensaries. Registered pancreatic cancer figures are significantly higher in the female population. The proportion of advanced pancreatic malignancies at primary diagnosis exceeds that of early stages.

Conclusion. The findings expose a demand for improving the system of early pancreatic cancer detection via intensifying preventive measures to capture the patient’s predisposition and screening techniques for early disease diagnosis. An active outpatient surveillance is prerequisite to an effective population involvement in dispensary screening.
