Title: N/A
Brief Summary: This study is designed to test:

1. in patients with negative positron-emission tomography (PET) after 2 cycles of BEACOPPesc chemotherapy: whether the number of cycles can be reduced without compromising progression free survival (PFS) (2 further cycles vs. 6 further cycles)
2. for patients with positive PET after 2 cycles: whether intensifying BEACOPPesc chemotherapy by adding Rituximab improves PFS.
