A 19-YO Woman with Huge Mediastinal Mass • She had history of chronic cough and night sweat for 1 month. She had no swelling of face nor upper extremities. • Left axillary and left lower cervival lymph node were palpated afterward. • Chest film showed large mediastinal mass. • CT chest and abdomen • A large lobulated anterior mediastinal mass (4.5x10x6.5 cm) involving prevascular space of superior mediastinum and surrounding SVC, brachiocephalic vessels, ascending aorta, aortic arch MPA, left main pulmonary artery without obstruction. Multiple small paraaortic LN above IMA origin • Atelectasis and obstructive pneumonia at lingular segment of LUL and bronchopneumonia at aterior segment of LUL
Echocardiography • Good LV contraction, LVEF 65.1%, no LA dilatation, no significant valvular dysfunction • No abnormal wall motion. No intracardiac shunt, no intracardiac mass, normal pericardium, no pericardial effusion
Lymph node biopsy, left cervical group • Diffuse large B-cell lymphoma, anaplastic variant • Some resembling Hodgkin or Reed-Sternberg cells • Lymphoma cells mark distinctly with CD20, not CD3 or EMA. Some mark with CD30 • Bone marrow biopsy • Negative for lymphoma cells • High LDH 1037 U/L (N 225-450), ECOG 2

Primary Mediastinal B-Cell Lymphoma (PMBL) • Large cells with polymorphic nuclei that have an abundant rim of clear cytoplasm. Fibrosis commonly results in compartmentalization of the neoplastic cells • Immunophenotyping demonstrates the presence of B-cell antigens in all cases (CD19, CD20, CD22 and CD79a). • Bcl-2 is expressed in 80% of cases, • CD10 is infrequently expressed and CD21 is negative. Surface immunoglobulin (sIg) expression is absent, • CD30 staining is common, but weak. • In contrast to HL, the transcription factors PAX5, BOB.1, Oct-2 and PU.1 are always expressed and CD15 is negative.

Diagnosis and Treatment • Diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma stage IIIBX • IPI = 3 (LDH, stage, ECOG); Bulky • Treatment • R-CHOP-21 x 8 cycles • After CR, autologous stem cell transplantation was done without prior radiotherapy
Interim PET after 2nd R-CHOP • A soft tissue density mass at left anterosuperior mediastinum, 4.5x6.0 cm at prevascular, paraaortic, AP window, lower paratracheal to left hilar region; no cervical lymphadenopathy • No FDG avidity at soft tissue density mass. Mild FDG avidity at left hilar node (residual tumor)
CT whole body after 4th R-CHOP • Decreased size of soft tissue mass at anterior mediastinum, 3.7x1.9x3 cm. No pericardial effusion • Decreased size of multiple lymph nodes at left gastric, EG junction, paraaortic, aortocaval, celiac region
PET/CT after 8th R-CHOP • No pathological size of lymph nodes in head and neck regions, normal orbits and paranasal sinuses • No pulmonary mass or nodule. An ill-defined isodensity mass in anterosuperior mediastinum (5x2.8 cm) occupying in prevascular space, paraaortic and AP window • No demonstrable mass or cyst or fluid in abdominal and pelvic cavity • No demonstrable bony destruction • IMP: complete response, no active lymphoma
Haematologica 2008;93:1364-71. • The recommended first-line therapy is chemotherapy and radiotherapy (grade B). An anthracycline-based chemotherapy with CHOP, MACOP-B or VACOP-B is recommended (grade B) • Patients with an inadequate early response should be candidates for early intensification with high-dose chemotherapy (grade C) • Patients with refractory or relapsed disease should undergo rescue programs including intensive, non-cross-resistant debulking treatment followed, in chemosensitive patients, by high-dose chemotherapy and ABMT (grade B).
