iv) Any one of the following cytopenia due to lymphoma:.

1. Platelets <100,000 cells/mm3 (100 x 109/L).
2. Absolute neutrophil count (ANC) < 1,500 cells/mm3 (1.5 x 109/L).
3. Hemoglobin < 10g/dL (6.25 mmol/L).
4. Pleural or peritoneal serous effusion (irrespective of cell content).

vi) Any compressive syndrome (for example, but not restricted to ureteral, orbital, gastrointestinal).
