The COVID-19 pandemic had an undeniable impact on the health system worldwide, this lead to a delay in the diagnosis and treatment of digestive cancers. The purpose of our study was to assess this delay and its impact on patient care. Our work is a retrospective study about 165 patients that were admitted for digestive cancers at Sheik Khalifa hospital, Casablanca morocco during a 3-year period, that we divided into three. We included all the digestive adenocarcinomas (esophagus excluded) whether they were operated on or not. We excluded all other types of cancers (GIST, serous tumors …). We assessed the time between the beginning of the symptoms and the beginning of the treatment and the number of patients that were diagnosed at the complication stage. We also assessed the staging of the tumor at the moment of diagnosis and the complete surgical resection rate. Among the 165 patients admitted for digestive cancer, 54,9% were males with a sex ratio of 1,22 M/F. The average age of our patients was 62,8 years varying between 25 and 86 years old and with a standard deviation of 11,8 years. Digestive cancers were diagnosed in 79 patients during period 1, 43 patients during period2, and 43 during period 3. We found a statistically significant increase in the percentage of patients with advanced cancer by 21,7% (p = 0,045) from 2019 to 2020. The delay in diagnosis (p = 0,275), percentage of cancer discovered at the stage of complication(p = 0,728), and the reduction in complete surgical resection (p = 0,177) were not statistically significant. Our results show an undeniable impact of the COVID-19 pandemic on the staging of digestive cancers but the impact on their care remains to be proven and needs a long-term survival follow-up. •This is study assesses the impact of The COVID-19 pandemic on the diagnosis delay in digestive cancers and its impact on their staging.•A three-year study that includes 165 patients, 1 year before the COVID-19 pandemic and two years during.•The pandemic had a statistically significant impact on the staging of the tumor but no impact on the short-term outcome of the patients.•The first study of its kind in Morocco.
