The general aim of the present study is to assess the role of PET for the staging and for the assessment of response and outcome prediction in Marginal Zone Lymphoma (MZL). This study will be conducted as a multicenter retrospective analysis of MZL for whom PET scan are available as DICOM file for central review.
The study is designed as a retrospective collection of patients with MZL enrolled in the prospective IELSG36 and IELSG38 trials sponsored by IELSG and in the observational NF10 study sponsored by Federazione Italiana Linfomi (FIL), with the possibility to add additional cases from participating institutions.
The study will be conducted on performed scans. No additional scan or procedure will be required for study purposes.
The study will be divided into two sections with different aims:
Part A will be conducted to understand the role of PET for the staging of MZL. PET scans will be analyzed and compared with data retrieved from CT scan and from other staging procedures, also including bone marrow biopsy, ultrasound, and laboratory exams. This part of the study will describe ability of PET to identify pathologic lesions and to contribute to staging definition or to stage migration.
Part B will be conducted to validate standardized criteria for response assessment in MZL including FDG-PET among procedures and to define the prognostic role of metabolic response in MZL. For this purpose the primary endpoint for this part of the study is defined as the progression free survival. Secondary endpoint will be Overall survival, and response rate defined with conventional procedures and rate of histological transformation.

A significant proportion of patients considered for this study will be retrieved from previous observational prospective clinical studies. Data on clinical presentation, treatment and follow-up will be obtained from the existing dataset of the previous protocols. For the additional cases identified from clinical practice data will be collected from patient chart. A unique study CRF will be prepared to collect all the required details.
Patients with histologically confirmed marginal zone lymphomas according to the current WHO classification are registered in the study. Moreover, patients characteristics (PS, systemic symptoms), Ann Arbor stage, laboratory parameters, serology for hepatitis C, B and human immunodeficiency virus, bone marrow aspirate and biopsy data, data on treatment start and end, chemotherapy details, final response defined according to Cheson 2014 and Matutes criteria, date of last follow-up ,occurrence of any event (relapse, progression, death) with date will be collected.
PET response will be initially coded according to local interpretation of scan report. All FDG-PET, will be then centralized to perform a blinded independent review of staging and response. Images will be centralized and examined by a panel of 3 nuclear medicine physicians that will independently review the scans. Each case will be evaluated by two reviewers. In case of discordant results a third reviewer will adjudicate the case.
Each patient enrolled in the study will be anonymized by assigning a unique identification numerical code upon registration in the study. The unique identification code will be used to record health-related data.
Anonymized PET data will be uploaded into the DICOM system by the responsible person of the site.
Anonymized health-related data will be collected in the e-CRF. At each site, the responsible of the research or a delegated person will complete the e-CRF.
Only the Study Chair and the Sponsor will have access rights for the health-related data and will be responsible for protection of the data.

Criteria for response assessment
- Correlation between CT and PET [ Time Frame: At baseline ]To correlate CT and PET results for stage definition
- Progression Free Survival (PFS) [ Time Frame: From date of enrollment until the date of first documented progression, or last follow up, or date of death from any cause, whichever came first, assessed up to a maximum of 10 years ]
- Duration of Response (DoR) [ Time Frame: From date of first response to the date of relapse, or last follow up, or date of death from any cause, whichever came first, assessed up to a maximum of 10 years ]DoR is evaluated only for responding patients
