COVID-19 in patients with neuroendocrine neoplasms: two-year results of the INTENSIVE study

: Preliminary results regarding 85 patients of the INTENSIVE study have been published in 2021. Now we are reporting the 2-year analysis. We conducted a retrospective/prospective worldwide study on patients with neuroendocrine neoplasms (NENs) and a molecularly proven SARS-CoV-2 positivity. Here we are reporting data from consecutive patients enrolled between June 01, 2020, and May 31, 2022. Among the 118 contacted centers, 25 were active to enroll and 19 actively recruiting at the time of data cut-off for a total of 280 patients enrolled. SARS-CoV-2 positivity occurred in 47.5% of patients in 2020, 35.1% in 2021 and 17.4% in 2022. Median age at COVID-19 diagnosis was 60 years. Well differentiated tumors, non-functioning, metastatic stage and gastroenteropancreatic (GEP) primary site represented most of NENs. COVID-19-related pneumonia occurred in 22.8% of the total, with 61.3% of them requiring hospitalization; 11 patients (3.9%) needed sub-intensive or intensive care unit therapies and 14 patients died (5%), in 11 cases (3.9%) directly related to COVID-19. Thoracic and other NEN primary site were associated with hospitalization for COVID-19 and with sub-intensive or intensive care. A significant decrease in both hospitalization and pneumonia occurred in 2022 versus 2020. In our largest series of NEN patients with COVID-19, the NEN population is similar to the general population regardless of COVID-19. However, older age, non-GEP primary sites and diabetes mellitus should be carefully considered for increased COVID-19 morbidity and mortality. Relevant information could be derived by integrating our results with NENs patients included in other cancer patients and COVID-19 registries.
