Studien-Informationen
Brief Summary:Merkel cell carcinoma (MCC) is a rare aggressive skin carcinoma. Approximately 80% of MCC are
related to the Merkel Cell Polyomavirus (MCPyV). Although rates of relapse are high, the
follow-up strategy lacks consensus. Patients are usually assessed clinically every 3 to 6
months for the first 2-3 years, and every 6 to 12 months thereafter. In the European
guidelines, patients with early stages are monitored with clinical examination and
ultrasonography of lymph nodes, while whole-body imaging is optional in patients with stage
III disease, on a yearly basis for 5 years. Such strategy may prevent the diagnosis of
infra-clinical recurrences, whereas patients could still be treated with surgery or radiation
therapy. Until 2017, patients with advanced disease were treated with chemotherapies, with no
long-term benefit. Immunotherapies with PD-1/PD-L1 inhibitors currently allow durable
responses in 50% of such patients. This major change in the management of MCC patients argues
for a follow-up strategy that would allow early diagnosis of infra-clinical metastases, when
tumoral burden is still low. Given that all patients cannot be monitored by systematic
regular imaging, additional non-invasive tools are needed. Blood-based biomarkers as a
surrogate of tumor burden are advantageous as they can be repeated over time, providing
guidance on when imaging is necessary. The study aims to assess two blood biomarkers, MCPyV
T-Ag antibodies and cell-free miR-375, in a prospective fashion from baseline diagnosis, in a
cohort of 150 European MCC patients
Ein-/Ausschlusskriterien
Inclusion Criteria:- Patients with a " de novo " diagnosis of MCC, confirmed on histological criteria
(neuroendocrine morphology, CK20 staining and/or neuroendocrine and/or SATB2 staining,
exclusion of differential diagnosis)
- ≥ 18 years of age
- Written informed consent obtained from the participant
Exclusion Criteria:
- Patients following any measures of legal presentation
- Pregnancy or breastfeeding
Studien-Rationale
Primary outcome:1. To assess the diagnostic performances of two blood biomarkers (T-antigen antibodies and miR375) in detecting disease recurrence during follow up of patients with Merkel Cell Carcinoma (Time Frame - 12 months):
Diagnostic performances (specificity, sensitivity, predictive values) of each biomarker will be assessed at the end of follow up, in relation with patients' outcomes (remission and recurrence).
Secondary outcome:
1. To assess if these two blood biomarkers (T-antigen antibodies and miR375) assessed at baseline are associated with prognosis and response to treatments. (Time Frame - 12 months):
Cox regression analysis will be performed to evaluate the clinical and biological factors associated with recurrence, death of disease, response to treatments.
