SURVIVAL OF STOMACH CANCER PATIENTS IN WESTERN KAZAKHSTAN: A REGISTRY-­BASED STUDY

Introduction: Stomach cancer is the fourth most common worldwide. Although there a lot of international evidence on survival stomach patients, data from Central Asia still scarce. Aims: To study one- and five-years patients its correlates in Western Kazakhstan. Methods: All histologically confirmed cases (ICD10 code: C16) registered 2015 to 2019 Aktobe region, Kazakhstan, were included registry-based historical cohort study. One- with 95 % confidence intervals (CI) was calculated by life tables method. Independent associations between studied using Cox regression presented as crude adjusted hazard ratios (HR). Results: Altogether, 793 new 587 deaths region over period. Sixty-five percent diagnosed at stage III or IV. The overall five-year 33.1 8.4 %, respectively. Significant differences functions across categories observed for (p < 0.001), morphological type 0.001) ethnic background = 0.017). After adjustment, only tumor remained significantly associated out come. Stage (HR 2.3, CI: 1.5-3.6) IV 4.4, 2.8-6.9) shorter compared reference category. Patients intestinal more likely survive longer 0.7, 0.6-0.8). Conclusions: High proportion advance low warrant urgent measures both population institutional levels. Preventive activities, increased awareness implementation routine screening should be among priority actions improve decrease mortality
