All the subjects had
received chemotherapy as well as external beam RT. The
last dose of RT was administered a mean of 2 months
before the study began (range 4months to 2 weeks). Radiotherapy
included the mantle field, the lymph nodes below
the diaphragm and the spleen. The total dose of radiation
to the upper body was between 36 and 40 Gy; for the
spleen it was between 10 and 20 Gy, and for the paraaortic
lymph nodes it was 20 Gy. Patients were given
chemotherapy in the years that followed.
