ABSTRACT
Background: During COVID pandemic, many cancer patients (pts) refused to come to hospital, suspending therapies, with ominous consequences. Based on positive (+) results of DOMONCOVID, our homecare project for COVID+ cancer pts, we created a new model of assistance, ONCOHOME, delivering cancer care at home to immune-compromised pts. We aim to provide data on feasibility, efficacy and costs of this innovative model. Material and Methods: ONCOHOME is a multicenter project involving 3 Cancer Center (CC) of the North of Italy: National Cancer Institute, San Raffaele in Milan and Cremona CC. We created an organizational homecare model based on a medical and nursing team with a car equipped for home visits and a secretariat managing patient calls, with a dedicated phone number. The team administers cancer care at home and provides pts with the same assistance usually delivered in hospital. Patientreported outcome (PRO) assessment is performed. Results: From August 3rd 2020 to May 5th 2021, 79 cancer pts were assisted at home by Cremona team, receiving oral (62 pts), subcutaneous (10pts) or intravenous therapy (7 pts). All types of cancer were included. 77% of pts had a metastatic disease, 88% had a PS ECOG 0-1. Median duration of assistance was 126 days [range 2-270 days]. Most of the pts received oral chemotherapy (41pts). TKIs (25 pts), hormonal therapy (12 pts), supportive care with denosumab and zolendronic acid (5 pts ) and immunotherapy (1 patient, pt) were successfully administered at home, too. 13 pts required hospitalization due to clinical complications. In this group, only 2 pts were admitted to hospital due to severe toxicity;in particular, 1 pt treated with trifluridin/ tipiracil developed febrile neutropenia and 1 pt treated with gefitinib reported Grade 3 diarrhea. Both pts were discharged and continued to be assisted at home. Conclusions: ONCOHOME showed that inpatient or outpatient cancer drug administration could be successfully replaced by home administration, for appropriate therapies and selected pts. This model is feasible at an affordable cost. The project is ongoing, planning to accrue other 100 pts for each center. ONCOHOME will be implemented with electronic devices for PRO evaluation, certified telemedicine service and non-invasive wearable smart tissue monitoring physiological parameters devices.
ABSTRACT
Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters into target cells by exploiting the cellular transmembrane protease serine 2 (TMPRSS2) for spike protein cleavage. Male gender, age, obesity, diabetes, hypertension are some of the factors related to coronavirus disease 2019 (COVID-19) severity and mortality. Prostate cancer (PCa) patients (pts) are expected to be at higher risk for COVID-19 due to age and disease related comorbidities. TMPRSS2 transcription depends on androgens and androgen receptor and it is significantly downregulated by hormone therapies commonly used to treat PCa in different settings. Supposing that in PCa pts androgen deprivation therapy (ADT) could hamper SARS-CoV-2 cell entry, we aim to evaluate if the presence of single nucleotide polymorphisms (SNPs) in the androgen responsive elements (AREs) in the TMPRSS2 promoter is associated to COVID-19 outcomes. Trial design: The present exploratory biological study is part of an ongoing retrospective-prospective multicenter cohort trial designed to verify whether PCa pts on ADT develop milder clinical presentation of COVID-19 than the general male population. The cohort trial collects real world data since February 2020 through regional databases that identified 200,000 potential pts to be enrolled to compare the clinical outcome of COVID-19 between PCa pts on active therapy (Study Group) and non-PCa pts (Control Group). Within the Study Group, we will compare the COVID-19 outcome between treatment subgroups: ADT alone, ADT plus antiandrogens, CYP17 inhibitors or chemotherapy. To identify SNPs in AREs of the TMPRSS2 gene and to describe possible associations with COVID-19 outcome, blood samples will be collected from 50 PCa pts treated at selected centers. Pts will participate voluntarily and sign an informed consent approved by local ethical committees. We will centrally perform PBMCs isolation and DNA extraction by using quiagen QIAamp DNA Mini Kit. SNPs will be evaluated with the Axiom™ Human Genotyping SARS-CoV-2 array. The effect of ADT will be corrected depending on identified SNPs and associated to COVID-19 outcome. The study is ongoing: we processed blood samples from 21 pts. Final results are awaited by the end of 2021. Legal entity responsible for the study: The authors.

ABSTRACT
Background: The prospective, multicenter, observational INVIDIa-2 study was designed to investigate the clinical efficacy of influenza vaccination in advanced cancer patients receiving immune checkpoint inhibitors (ICIs) from October 2019 to January 2020. The primary endpoint was the incidence of influenza-like illness (ILI) until April 30, 2020. All ILI episodes, laboratory tests, complications, hospitalizations and pneumonitis were recorded. Therefore, the INVIDIa-2 study prospectively recorded all the COVID-19 ILI events. Methods: Patients were included in this non-prespecified COVID-19 preliminary analysis if potentially exposed to Sars-Cov-2 infection, namely alive on January 31, 2020, when the Italian government declared the National emergency. The incidence of confirmed COVID-19 was assessed among patients with ILI symptoms, describing the hospitalization rate and mortality. Cases with clinicalradiological diagnosis of COVID-19 without laboratory confirmation (COVID-like ILIs), were also reported. The COVID-incidence was exploratively compared basing on influenza vaccination. Results: 1260 patients receiving ICI were enrolled between October 2019 and January 2020;955 patients were analyzed according to the inclusion criterion. Of them, 66 patients had ILI from January 31, to April 30, 2020. 9 were COVID-19 ILIs with laboratory test confirmation. The COVID-19 ILI incidence was 0.9% (9/955 cases), with hospitalization rate of 100% and mortality rate of 67%. Including 5 COVID-like ILIs, the overall COVID-19 incidence was 1.5% (14/955), with hospitalization in 100% of cases and mortality rate of 64%. COVID-19 incidence was 1.2% for patients vaccinated against influenza (6/482 cases) and 1.7%, among unvaccinated patients (8/473 including 3 confirmed COVID-19 and 5 COVID-like), p = 0.52. The difference was not statistically significant, and the clinical trend in favor of vaccinated patients was lost when considering only confirmed COVID-19 (1.2% in vaccinated vs 0.6% in unvaccinated patients, p = 0.33), probably due to the greater presence of male and elderly patients in the vaccinated group (p = 0.009). Conclusions: We obtained the first prospective epidemiological data about symptomatic COVID-19 in advanced cancer patients receiving ICIs. The overall symptomatic COVID-incidence is meaningful, requiring hospitalization in all cases and leading to a high mortality rate, likely due advanced cancer more than to ICI therapy [Mengyuan Dai, Cancer Discov 2020].
