Reduction in the Number of Diagnoses of Upper Digestive Tract Cancer during the Covid-19 Pandemic: An Integrative Literature Review

Abstract

Introduction: In 2019, the World Health Organization was alerted about cases of infection with COVID-19. Due to the measures taken to prevent contamination, many pre-scheduled consultations, treatments and exams were suspended or cancelled. Objectives: This study aims to identify literature data on upper digestive tract cancer diagnosis numbers in patients that had performed endoscopy during the COVID-19 pandemic, along with a pre-pandemic control group. Methods: A literature review was performed through searches on the SciELO, Science Direct, PubMed, and BVS Regional Portal platforms. After applying the inclusion and exclusion criteria, 8 articles were selected for the study. Results: All articles reported a decrease in diagnoses of upper digestive tract cancer (reduction ranged from 76.3% to 19.28%) and in endoscopies performed (reduction ranged from 87.5% to 43.1%) during the pandemic. Conclusion: The COVID-19 pandemic reduced the accessibility of resources and; consequently, increased the number of underdiagnoses of pathologies with no direct relationship with the coronavirus. Thus, a significant reduction in the number of diagnoses of upper digestive tract cancer was observed due to the decline in the number of endoscopies performed.
