Background: The impact of coronavirus disease 2019 (COVID-19) has been overwhelming on patients with cancer, who may be at higher risk of developing severe disease. During the second COVID-19 outbreak in Italy, we planned universal microbiologic screening for patients scheduled for antineoplastic treatment., Methods: All patients with planned active treatment at Brescia University Radiation Oncology Department were screened for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA with repeated nasopharyngeal swabs (NPS) from October 31, 2020. Treatment continuation, suspension, or delay was modulated for patients testing positive according to clinical presentation., Results: From October 31, 2020, to February 6, 2021, 636 patients were enrolled and 1243 NPS were performed, of which 28 (2.25%) were positive. The infection rate was 2.52%; 81.3% of the patients with a positive NPS were asymptomatic, 2 had mild disease, and 1 severe disease that led to death. All patients already on treatment with mild or asymptomatic COVID-19 carried on the therapy with no or minimal delay. Median delay for patients with infection detected before treatment start was 16.5 days., Conclusions: Detected incidence of COVID-19 was lower during the second outbreak in our patients (2.52% vs 3.23%), despite the extensive testing schedule, and substantiates the high rate of asymptomatic infections and the low mortality among patients with COVID-19 (6.3% vs 38.5% during the first outbreak). Universal SARS-CoV-2 screening for all patients with planned treatment might allow early identification of patients with COVID-19, resulting in timely management that could improve clinical outcomes and prevent spread of the infection.

Background: Coronavirus Disease 2019 (COVID-19) pandemic had an overwhelming impact on healthcare worldwide. Outstandingly, the aftermath on neoplastic patients is still largely unknown, and only isolated cases of COVID-19 during radiotherapy have been published. We will report the two-months experience of our Department, set in Lombardy "red-zone"., Methods: Data of 402 cancer patients undergoing active treatment from February 24 to April 24, 2020 were retrospectively reviewed; several indicators of the Department functioning were also analyzed., Results: Dedicated measures allowed an overall limited reduction of the workload. Decrease of radiotherapy treatment number reached 17%, while the number of administration of systemic treatment and follow up evaluations kept constant. Conversely, new treatment planning faced substantial decline. Considering the patients, infection rate was 3.23% (13/402) and mortality 1.24% (5/402). Median age of COVID-19 patients was 69.7 years, the large majority were male and smokers (84.6%); lung cancer was the most common tumor type (61.5%), 84.6% of subjects were stage III-IV and 92.3% had comorbidities. Remarkably, 92.3% of the cases were detected before March 24. Globally, only 2.5% of ongoing treatments were suspended due to suspect or confirmed COVID-19 and 46.2% of positive patients carried on radiotherapy without interruption. Considering only the last month, infection rate among patients undergoing treatment precipitated to 0.43% (1/232) and no new contagions were reported within our staff., Conclusions: Although mortality rate in COVID-19 cancer patients is elevated, our results support the feasibility and safety of continuing anticancer treatment during SARS-Cov-2 pandemic by endorsing consistent preventive measures.

Aims and Background: To present the Italian state-of-the-art contribution to radiobiology of external beam radiotherapy, brachytherapy, and radionuclide radiotherapy., Methods and Study Design: A survey of the literature was carried out, using PubMed, by some independent researchers of the Italian group of radiobiology. Each paper was reviewed by researchers of centers not comprising its authors. The survey was limited to papers in English published over the last 20 years, written by Italian investigators or in Italian institutions, excluding review articles., Results: A total of 135 papers have been published in journals with an impact factor, with an increase in the number of published papers over time, for external beam radiotherapy rather than radionuclide radiotherapy. The quantity and quality of the papers researched constitutes a proof of the enduring interest in clinical radiobiology among Italian investigators., Conclusions: The survey could be useful to individuate expert partners for an Italian network on clinical radiobiology, addressing future collaborative investigations.
