Background• Particular clinical and pathological entity in the
REAL/WHO classification. • Female predominance with median age less than
30 years.• Predominat or exclusive mediastinal involvement.• Bulky mediastinal mass invading adjacent organs
(lung, vena cava, pleura, pericardium and chest wall) producing vena cava compression.
May be hematological emergency !!!!!!!

Primary Mediastinal B Cell Lymphoma (PMBCL)
• Patients were defined as having PMLBL (Hamlin 2004 ASH) if they showed all the following:
– a clonal lymphoid proliferation with a DLBC centroblastic or immunoblastic histology
– a mediastinal mass greater than 5 cm with or without contiguous extranodal or supraclavicular involvement
– no detectable extramediastinal mass greater in size than the primary mediastinal lesion

• PS>2, increased LDH, pleuro-pericardial effusion, IPI ? • Early response to initial therapy
• Extranodal disease (kidney,ovary,CNS,liver).
• Decrease of dose intensity
• Residual mass TC positive.

DLBCL: role of consolidation radiation therapy
• In a randomized study ( level 1+) the use of consolidation IFRT on bulky sites of disease was compared to no further treatment The IFRT produced a better control of disease, reduced significantly relapses on site of bulky and improves PFS and OS. ( Aviles 1994).
• Two prospective trials (level 2+) confirmed that IFRT significantly reduced local relapses in patients with bulky disease improving PFS and OS. (Schlembach 2000, Ferreri 2000).
• Two retrospective studies (level 2-) patients treated with CHT + IFRT showed a significantly reduction of recurrence on site of bulky disease compared to CHT alone. (Wilder 2001, Fuller 1995)

Raccomandazioni (2)• The recommended first-line therapy is a
chemotherapy and radiotherapy association (grade B).
• An antracycline-based chemotherapy with
CHOP, MACOP-B or VACOP-B is recommended (grade B).
• Mediastinal RT should start within 8 weeks from the last dose of chemotherapy. A dose of at least 30 Gy should be delivered to the original tumor volume. (grade B)

Aims of the trial
Primary objectives:To analyse the phenotype and molecular characteristics of Primary Mediastinal Large B-cell Lymphoma
To determine the PET response rate following chemo-immunotherapy
Secondary objectives:To obtain data, on a non-randomised basis, regarding the outcomes of treatment using different chemotherapy regimens.
The impact of mediastinal radiotherapy depending upon the practice of the participating institutions.
Progression free and overall survival will be analysed.

RegistrationPatients will be centrally registered at the IELSG Coordination and Data Management Office.
Patients enrolled from IIL institutions will be centrally registered at the I.I.L Data Center, Modena:
For I.I.L. centers Data Center, Modena www.iilinf.it From IIL Data Center the registration form should be submitted to IELSG Study Coordination and Data Management Office IELSG Study Coordination and Data Management Office:Fax: +41 91 811 91 82 E-mail: [email protected]
Patients fulfilling the eligibility criteria will then be registered and a notification sent back within 48 hours to the investigator.
Treatment should start within 15 days from registration.

Raccomandazioni (4)• Patients should receive an early evaluation with CT scan
during the first courses of chemotherapy (about half of the programmed courses), in order to identify patients with inadequate response, i.e. less than partial response (grade D).
• Patients with an inadequate early response should be candidate to early intensification with high-dose chemotherapy (grade C).
• At the end of chemotherapy, patients should be evaluated with CT scan and PET, in order to assess a progression occurred in the second half of the chemotherapy period (grade D).

Raccomandazioni• No definite recommendation can be currently
formulated for patients without a bulky disease who achieve a PET-negative state at the end of chemotherapy: radiotherapy is less strongly recommended in such a clinical subset.

Zevalin®
• Razionale per l’uso di Zevalin® nel trattamento dei LNH:
- Le cellule del linfoma sono radiosensibili
- Zevalin® distrugge anche le cellule tumorali non direttamente legate
effetto di “fuoco incrociato”
- È efficace nei tumori “bulky” o poco vascolarizzati
- Più sedi di malattia possono essere trattate simultaneamente
- L’esposizione alle radiazioni dei tessuti sani è limitata
