Brief summary
Evaluating the vaccination willingness in oncologic patients over six months as well as estimating the effects of radiotherapy/systemic anticancer treatment on the efficacy and toxicity of currently approved SARS-CoV-2 vaccines
Detailed description
All patients that present themselves newly at the outpatient-clinic of the Department of Radiooncology at the Ordensklinikum Linz GmbH, Barmherzige Schwestern during a period of six months are eligible for participation. After being informed about the study, the participants answer a short structured interview regarding vaccination status and vaccination willingness. Patients who already received one or two doses of SARS-CoV-2 vaccine are eligible for the study's subpopulation 1, with the main focus of quantifying SARS-CoV-2 S binding antibody titres after at least 35 days from initial vaccination. Patients who are to receive at least one dose of vaccine during or up to six weeks after radiotherapy are eligible for subpopulation 2, comprising serial measurements of SARS-CoV-2 S binding antibody titres before and after vaccination.

Inclusion criteria
Study population for the cross-sectional study (patients with previous SARS-CoV-2 infection of previous vaccination, evaluation of willingness to get vaccinated: * Patients with solid tumors/haematooncologic diseases regardless of stage that seek treatment in the outpatient clinic of the department of radiooncology from April to September 2021 who will undergo active treatment. * Age: 18-120 years Patients that undergo radiotherapy, radio-chemotherapy, radio-hormonotherapy or radio-immunotherapy during the investigation period. Longitudinal study: * Patients that have not yet received SARS-CoV-2 vaccination, but are scheduled to get the first dose during or up to six weeks after active therapy. * Age: 18-120 years
Exclusion criteria
