Patients and Health Staff of Cancer Centres During the Covid-19 Pandemic (PAPESCO-19)

Patients and Health Staff of Cancer Centres During the Covid-19 Pandemic: Constitution of a Biological Collection Linked to a Prospective, Multicenter Cohort Study

The Covid-19 has, in a few weeks, made the world tremble: the number of deaths (mainly elderly and / or co-morbid) continues to increase, the confinement causes the collapsing of the economy and the decline of relationships inter-human. The data are too fragmented and the disease too recent to know its repercussions on the 3 million French people who have or have had cancer. The investigators would like, in 3 populations: * patients in treatment, * or in follow-up and * health personnel, to constitute a large prospective and longitudinal database of data: i / serological: humoral response, test performance, monitoring of serum immunoglobulin levels , reinfection threshold,…; ii / clinical: incidence, severity, mortality and their favorable factors impact of cancer treatment on Covid-19 infection and modification of the quality of oncological care in the context. In parallel, on a more limited sample of establishments, it will be : * appreciate the economic and functional repercussions, * will try to find out about the infection modalities in patients and health personnel and * will appreciate the levels of anxiety and depression to which health staff are subject.

The participation of the study will be offered to each patient when they will come to the centre (by oncologist, radiotherapist, surgeon, ...). For the health staff, the information can be delivered through different channels (posting, mail, mail, intranet...). This will make the informed consent available to all staff. Participation will be voluntary: staff who have read the information note and wish to participate in the study will have to register on the "PAPESCO-01" screening schedule, during which they will sign their consent with the occupational physician (or anyone delegated by occupational medicine), then have their first sample and complete the various questionnaires. The screening of the patients and of the health staff will be done by 2 or 3 techniques depending of the results. The first technic is a blood test done at M0 (inclusion), M3, M6, M9 and M12 and on demand in case of Covid-19 symptoms (rapid serology (immediate analysis), ELISA serology (differed analysis on frozen sample), genotyping of FCGR2A and FCGR3A gens (only at M0)). The second technic nasal swab test (RT-PCR) is done only in case of symptoms (whatever the result of the minute test is) for the hospitalized patients. The results of the tests realised in town will be get back through the questionnaires. The third technic is the questionnaires to the patients and the health staff.

Diagnostic test for SARS-CoV2 : Blood test to analyse the IgG and IgM with an immediate qualitative analysis (serological test) and a differed quantitative analysis (ELISA test) Results of nasal swab that will allow extracting the RNA and realizing a RT-PCR (only if the participants present symptoms). It will be obtained by standard local laboratories. Questionnaires (based on serology, clinic, economy (socio-demographic and lifestyle questionnaire) and epidemiology)

Establishment of a clinical basis for to describe the number and severity of Covid-19 infections in Cancer centres staff and patients.

Establishment of a biological basis for to describe the number and severity of Covid-19 infections in Cancer centres staff and patients.

The biological basis will be done through the serologic status (rapid immunochromatography test) and IgM and IgG titles (immuno-enzymatic assay like ELISA) performed at M0. The result of the SARS-CoV-2 coronavirus genome detection tests (molecular test by RT-PCR) conducted in town will be collected by questionnaire.

Establishment of a biological basis for to describe the number and severity of Covid-19 infections in Cancer centres staff and patients.

The biological basis will be done through the serologic status (rapid immunochromatography test) and IgM and IgG titles (immuno-enzymatic assay like ELISA) performed at M12. The result of the SARS-CoV-2 coronavirus genome detection tests (molecular test by RT-PCR) conducted in town will be collected by questionnaire.

The evaluation will be done through the dosage of IgM and IgG anti-SARS-CoV2 at different time of measurement M0, M3, M6, M9 and M12 using a qualitive immunochomatographic test and quantitative ELISA test.

The result obtained by the qualitative minute test for IgM will be compared to the quantitative ELISA test to know the specificity, sensitivity, positive predictive value, negative predictive value

The quantification of IgG level at M12 will be obtained by using the quantitative ELISA test for patients in cancer centres and health staff.

The evaluation will be done on subjects who had previously developed IgG and have clinical signs of Covid-19. The signs will be confirmed by RT-PCR which detect the RNA of SARS-CoV2 using a nasal swab test.

The evaluation is based on whether or not a reinfection occurs during follow-up and it will be done by the concentration of IgG anti-SARS-CoV2 using the quantitative ELISA test.

Evaluate the influence of polymorphisms of receptor of IgG Fc-gamma low-affinity (FcδIIA, FcδIIIa) on the humoral immune response

The evaluation will be done by analysing the anti-SARS-CoV2 antibodies according to the FCGR2A and FCGR3A genotypes using RT-PCR

Evaluate the severity of Covid-19 infection (invisible, visible, prolonged, severe and fatal) by age group

The evaluation will be done by knowing the number of Covid-19-realated death, severe infections (oxygen therapy needed), moderate infections, prolonged symptomatic infections and asymptomatic infections reported to all subjects with a positive serology and/or a positive RT-PCR test.

Evaluate the frequency of reinfection by Covid-19 (recurrence of evocative clinical symptoms and positive viral PCR or positive IgM serology) during follow-up

The evaluation will be done by knowing the number of subjects who have a recurrence of clinical symptoms and/or positive SARS-CoV2 RT-PCR and/or a positive IgM serology (by the quantitative ELISA test or the qualitative minute test)

Evaluate the risk factors (clinical and therapeutic) to develop severe forms of Covid-19 infection in patients

The evaluation will be done on subjects who have a seropositivity and/or a positive SARS-CoV2 RT-PCR and/or a positive IgM serology (by the ELISA test or the minute test). The factors that are significantly associated to severe forms or mortality are : current or recent cancer treatment (Immunotherapy, chemotherapy based on the frequency of grade 3/4 neutropenia and/or lymphopenia), radiation therapy, surgery), concomitant treatment, comorbidities, type of cancer and stage, cancer-related medical history, biological markers

The evaluation will be done by using the PMSI (Program of medicalisation of information systems). This program allows describing the medical activity in health establishment. It is divided in 4 domains: MCO (Medicine, Surgery, Obstetric and Odontology), Follow-up care and rehabilitation, psychiatry, and home care

The evaluation will be done by identifying the monetary value of resources mobilized more or less according to the observed changes at the level of modifications in patient treatment scheme (e.g. chemotherapy, radiotherapy and surgery), teleconsultations, and diagnostic of new cancers

The evaluation will be done by knowing the number of health staff sick leave. The information will be obtained with the human resources data and work medicine.

The incidence will be obtained by counting the number of subjects infected by SARS-CoV2 (patients and health staff) every four months

Evaluate the distribution of risk factors for contamination in patients and in the general population

The evaluation will be done by doing percentages (qualitative factors) / Average or median (quantitative variables) using the Constances cohort for the general population

The evaluation will be done before the screening, 3, 6, 9 and 12 months after the screening through the STAI state (State-Trait Anxiety Inventory) questionnaire with 20 items. It evaluates the felling of apprehension, tension, nervousness, anxiety. It is composed of 20 questions. Each answer is noted form 1 to 4. A high score (more than 48 for men and 55 for women) represents a high level of anxiety.

The Depression is evaluated before the screening, 3, 6, 9 and 12 months after the screening through the HADS (Hospital Anxiety and Depression Scale) questionnaire with 14 items. Each answer is coded from 0 to 3.The global score variates from 0 to 42. A high score (from 15 to 42) represents the existence of an anxio-depressive syndrome.

The post-traumatic development is evaluated with the PTGI (post-Traumatic Growth Inventory) with 21 items. Each answer is noted from 0 to 5. A high score represents a change to a very great degree. It evaluates the positive changes perceives such as relating to others, news possibilities, personal strength, spiritual change and appreciation life

The evaluation will be done by analysing the number of time the health care of the patient has been changed using the medical file of the patient.

The evaluation will be done by analysing the medical file of the patient and calculate the number of patients for which the health care has been changed.

The rate of morbidity will be obtained by calculating the number of new cases of disease occurring during the study with the help of the medical file of each patient.
