The goal of this observational study on chimeric antigen receptor T-cell therapy is to monitor the feasibility, efficacy, toxicity and biomarkers in a real life setting. Partecipants will be asked to agree to their clinical data collection and to partecipate to the optional biological study that aims to evaluate biomarkers of toxicity and response (clinical characteristics, cytokine profile, cellcomposition and type of the CAR-T cell product, lymphoma genomics). The study will evaluate even the disease response according to lugano criteria by PET and CT in routine clinical activity.
This observational prosopective multicenter study aims to: 1. evaluate the feasibility of CAR T-cell treatment in the real-life setting, with particular regard to eligible patients versus those subjected to leukapheresis versus those finally treated. 2. evaluate the survival outcome of PMBCL, DLBCL, MCL and FL patients treated with CAR T-cells versus those potentially eligible, but excluded from cellular therapy for other causes (either related to the patient or to the manufacturing); 3. monitor the incidence of early and late AEs up to three year after CAR-T; 4. evaluate disease response and immune recovery biomarkers at different time-points up after CAR-T (when clinically indicated or using blood sampling leftover); 5. evaluate biomarkers of toxicity and response (clinical characteristics, cytokine profile, cell composition and type of the CAR T-cell product, lymphoma genomics). 6. evaluate disease response according to Lugano criteria by PET and CT in routine clinical activity.

The screening will be done according to the axi-cel, tisagen-cel, brexucabtagene autoleucel and lisocabtagene maraleucel label criteria, the eligibility of a given patient to CAR-T will be definedaccording to AIFA criteria. All patients eligible to CAR-T will be consecutively enrolled Biological samples will be stored at each institution or centralized at the Fondazione IRCCS Istituto Nazionale dei Tumori, Milano. Fondazione Italiana Linfomi (FIL) will be in charge of the GCP management of the study. Web-based CRF are prepared by FIL.

RECRUITINGFeasibility of the CAR-T cells treatment in lymphomas in the italian real life practice
Evaluate the feasibility of CAR T-cell treatment in the real-life setting, with particular regard to eligible patients versus those subjected to leukapheresis versus those finally treated. The percentage of patients infused will be estimated as the number of patients infused divided by the total number of those declared eligible; the corresponding exact confidence intervals at 95% will also be estimated.
Time frame: 10 years enrollment, minimum 1 year follow-up
Efficacy of the CAR-T cells treatment in lymphomas in the italian real life practice
Evaluate the survival outcome of PMBCL, DLBCL, MCL and FL patients treated with CAR T-cells versus those potentially eligible, but excluded from cellular therapy for other causes (either related to the patient or to the manufacturing)
Time frame: 10 years enrollment, minimum 1 year follow-up
Evaluation of Outcome: Overall Response rate (ORR), according to Lugano criteria.
Overall response rate (ORR): the percentage of responding patients will be estimated as the number of patients with complete response (CR) + partial response (PR) divided by the total number of patients assessable at each specific timepoint (3-6-12-18 months). Patients not assessable for response for any reason will be considered as non-responding in the calculation of the response rate. The exact 95% confidence intervals of the response percentage will also be estimated.
Time frame: 10 years, minimum f-up 1 year
Evaluation of Outcome: Overall survival (OS), according to Lugano criteria.
Overall survival (OS): time will be measured as the interval between the date of CAR-T infusion and the date of death for all causes, with censoring at the date of the latest follow-up in alive patients. OS curves will be estimated with the Kaplan Meier method.
Time frame: 10 years, minimum f-up 1 year
Evaluation of Outcome: Progression free survival (PFS)
Progression-free survival (PFS): time will be measured as the interval between the CAR-T infusion and the date of progression disease (PD), or death, whichever occurs first.
Time frame: 10 years, minimum f-up 1 year
Evaluation of Outcome: duration of response (DoR)
Duration of Response (DoR): for patients who will respond to treatment, the duration of response will be measured as the interval between the response achievement and the date of progression or death, whichever occurs first, with censoring at the date of the latest follow-up in alive patients without progression. DoR curves will be estimated with the Kaplan Meier method.
Time frame: 10 years, minimum f-up 1 year
Evaluation of Outcome: Overall Response rate (ORR)
Overall response rate (ORR): the percentage of responding patients will be estimated as the number of patients with complete response (CR) + partial response (PR) divided by the total number of patients assessable at each specific timepoint (3-6-12-18 months). Patients not assessable for response for any reason will be considered as non-responding in the calculation of the response rate. The exact 95% confidence intervals of the response percentage will also be estimated.

Evaluation of Outcome: non-relapse mortality (NRM)
Non-relapse mortality (NRM) after CAR-T cell therapy: time will be measured as the interval between the date of treatment start and the date of non-relapse death, with censoring at the date of the latest follow-up in alive patients without relapse. NRM cumulative incidence curves will be estimated regarding disease recurrence as competing event, and between groups comparisons will be performed using the Gray test.
