Modelos de supervivencia y georreferenciación en pacientes portadores de cáncer prostático atendidos en la unidad Solca Ambato, 2003-2018

Abstract

The current degree work aimed to design a survival model in patients with prostate cancer, and thus apply it to a geographic information system. The data matrix was obtained by collecting information from 311 medical records of men treated with this pathology at the Oncology Unit of Solca Ambato, period 2003-2018, considering 2 quantitative variables and 12 qualitative variables. To determine the behavior of the variables, a descriptive analysis was carried out. In the patients seen, the average age that prostate adenocarcinoma pathology appeared was at 78 years. 66.88% of these patients were from the province of Tungurahua, 19.61% of the patients received urological control, 19.6% presented urinary problems and 12.22% presented blood problems. After having received a treatment administered by the doctor of the institution, 92.60% of the cases were kept alive, in a median survival time of 302 days and a possible survival interval of 165 and 438 days, the influential variables for patient’s survival were "administered drug" and "treatment" whose p value was 0.00 where the model identified that there are significant differences between the variables, identifying drug 2 (bucalutamide 50 mg + docetaxel + enzalutamide+ flutamide + leuprolide) and treatment 5 (control with ciprofloxacin) as the most effective for survival in a 95% confidence interval. The province of Tungurahua was identified as the most vulnerable area due to the highest concentration of cases. It is recommended that both public and private entities provide priority aid to those most vulnerable areas, which allow identifying nutrition problems, basic services, health and hygiene in the areas where the highest concentration of cases is found.
