Condition: Premalignant Conditions · Malignant Lesions · Gastric · Sponsor: Portuguese Oncology Institute, Coimbra
Gastric cancer is the fifth cause of cancer-related mortality worldwide. Gastric carcinogenesis involves the progression from premalignant conditions such as atrophic gastritis and intestinal metaplasia to premalignant lesions like dysplasia, and ultimately carcinoma. Most diagnoses of gastric cancer are made at advanced stages, with a five-year relative survival rate of 36%. Therefore, early detection of premalignant conditions and lesions is crucial, as it allows for timely surveillance and treatment, which can improve patient survival. Upper gastrointestinal endoscopy (UGE) is the first-line examination for diagnosing upper gastrointestinal tract pathology, particularly oncological conditions. The European Society of Gastrointestinal Endoscopy (ESGE) and the United European Gastroenterology (UEG) have established that UGE quality is a priority, identifying specific quality parameters, such as the duration of the procedure, which is the most extensively studied parameter. According to ESGE recommendations, all UGE reports should include the procedure time (goal: ≥90% of reports), which should be seven minutes or longer for surveillance of intestinal metaplasia. This time threshold follows a study that established a causal relationship between longer procedures (≥ seven minutes) and a higher detection rate of premalignant gastric conditions and lesions. Subsequent observational studies have generally shown that setting a minimum procedure time increases the detection rate …
