Extranodal lesions (outside lymph node or nodal mass, but including liver and spleen) \>10 mm in long AND short axis 5. ECOG performance status 0-2 6. Adequate organ function: a. Kidney function defined as: i. Serum creatinine estimated glomerular filtration rate GFR ≥ 30mL/min b. Hepatic function defined as: i.
