Investigation • CT guided lung Bx Lymphoma Primary Pulmonary Lymphoma
Primary Pulmonary Lymphoma • Lymphomatous proliferation can involve the lung in three ways: Hematogenous spread of HD or NHL Contiguous invasion from LN Primary pulmonary involvement PPL Eur Resp Jr 2002
Primary Pulmonary Lymphoma • Definition: Clonal lymphoid proliferation affecting lung (parenchyma or airway) without extrapulmonary involvement at Dx or during subsequent 3 months Eur Resp Jr 2002
Primary Pulmonary Lymphoma • PPL includes: MALT NHL Multifocal mucosa associated lymphoid tissue Satellite nodes Lymphamatoid granulomatosis • Very rare 0.5-1% of 1ry pulmonary malignancy 3-4 % of extranodal NHL (25-50% of NHL) Eur Resp Jr 2002
Primary Pulmonary Lymphoma • Classification: Bronchial MALT most frequent Pesudolymphoma Slowly progressive & relative benign histology 90% correspond to MALT NHL No documented triggering antigen for bronchial MALT ( H.pylori equivalent ) ?Autoimmune diseases Eur Resp Jr 2002
Primary Pulmonary Lymphoma Bronchial MALT 58-87 % of PPL Age of onset 50-60 y 50 % of pts are asymptomatic radiological B symptoms in 25% Alveolar opacity with air bronchogram 50% Bilateral 60-70% BAL B lymphocytes > 10% Eur Resp Jr 2002
Primary Pulmonary Lymphoma Bronchial MALT Bronchoscopy N , mucosal inflammation or stenosis Bx shows 1) lymphoid proliferation 2) lymphoepithelial lesion 3) Blastic changes Peribronchovascular distribution Concomitant other mucosal MALT 25-35% BM involvement < 20% Eur Resp Jr 2002
Primary Pulmonary Lymphoma Bronchial MALT Other work up ENT , GI scopes SPE {High B2 microglobulin poor prognosis} 5y survival > 80% Progression faster than GI MALT No difference in prognosis with TNM ,histology or bilateral disease Ann Thoracic Sx 2000
Primary Pulmonary Lymphoma Bronchial MALT No consensus on Rx Surgery for localized disease Chemo for bilateral , extrapulmonary disease Combination Vs single agent no difference Radiotherapy is not used Heme Onc 1983 Cancer 1985
Primary Pulmonary Lymphoma • High Grade PPL 11-19% of PPL Age 60y Solid organ Tx , HIV , Sjogren Syndrome Pts symptomatic fever ,wt loss Single pulmonary mass Multiple cavitatory lesions in HIV Eur Resp Jr 2002
Primary Pulmonary Lymphoma • High Grade PPL Higher yield from transbronchial Bx higher mitotic activity & endoluminal invasion Prognosis poor Rx combined surgical & chemo Eur Resp Jr 2002
Primary Pulmonary Lymphoma • Lymphomatoid Granulomatosis 500 – 600 reported cases Age 30-50 y males > females Most Pts symptomatic Bilateral lower lobe predominance Peribronchovascular tend to cavitate Eur Resp Jr 2002
Primary Pulmonary Lymphoma • Lymphomatoid Granulomatosis Extrapulmonary involvement skin , renal , joints , peripheral & central nervous system Bx nodular , polymorphous no granuloma formation vascular tropism 3-4 y survival Rx Cyclophosphamide + predinsone Eur Resp Jr 2002
