Mediastinal large cell lymphoma. An uncommon subset of adult lymphoma curable with combined modality therapy.
Thirty adults with large cell lymphoma predominantly localized to the mediastinum diagnosed at the Massachusetts General Hospital between 1976 and 1985 were identified. The median age of the 20 females and 10 males was 34 years. All but one presented with symptoms due to an enlarging mediastinal mass, which was localized in 22 patients (73%) and exceeded 10 cm in maximal diameter in 65%. Superior vena cava syndrome and large pleural and pericardial effusions were common. Employing CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone) and consolidation radiation therapy in most cases, 80% achieved a complete remission and 59% survive failure-free at 5 years by actuarial calculation. The size of the mediastinal mass adversely affected failure-free survival (89% vs. 40%, P less than 0.05). No other pretreatment risk factor predicted outcome, but more intense chemotherapy was associated with improved survival (P = 0.035). Large cell mediastinal lymphoma is a locally invasive, often bulky malignancy with a predilection for young women; disease of low or moderate bulk is curable with full dose CHOP chemotherapy and consolidation radiation, but bulky disease requires more aggressive treatment.
