Fifteen patients (P = 0.02); for patients with intestinal involvement, only I only RT, one only surgery: stage and the presence of MHI were significant (P = 0.001 d CT either as initial treat- and 0.006 respectively). ment (eight CHOP, four RT + COP) or as salvage therapy (one COP), and 12 were receiving CT at time of death (five CHOP, one BEAM, one COP, 2RT + COP, one Chloram- bucil, two Mitoxantrone). Prognostic factors On univariate analysis the most markedly significant factors related to overall survival were stage (P = 0.003) and MALT status (P = 0.004), with localised stage and evidence of tumour origin from MALT being associated with relatively high survival.
