We retrospectively attempted to analyse prognostic factors in a group of 26 patients with centrocytic lymphomas (CCL) treated from 1979 to 1991 (representing 7% of all cases of NHL diagnosed in our institution during that period). Ten of the patients were females and 16 males, and their median age at diagnosis was 69 years (range 38–85). The majority of patients (77%) had advanced disease (Ann Arbor stage III-IV) at presentation. Twenty-two patients (85%) had good performance status (0–1 ECOG). B-symptoms were present in 10 cases. Most patients (87%) presented with generalized adenopathies. Bone marrow involvement was observed in 12 patients (46%) and Waldeyer's ring involvement in 5 (4 of them with stage 1–11). In 5 cases the liver was involved and 3 pts had gastrointestinal localizations; 15 patients had more than 2 sites of disease: LDH elevation was observed in 8/24 pts. Fourteen patients (54%) received single-agent chlorambucil (3 pts) or CVP (11 pts). Eleven patients were treated with ADM-containing regimens (7 with CHOP or M-ACOD and 4 with 3rd generation regimens). One patient had radiotherapy alone.

The complete response (CR) rate was 50% (13/26); 8 patients relapsed with a median time to progression of 19 months, and only 3 responded to salvage treatment. The median overall survival was 33 months, with fewer than 40% of patients surviving longer than 3 years. At univariate analysis the use of ADM-containing regimens seems significantly correlated with the CR rate (p = 0.047), the failure-free survival (p = 0.023), and the overall survival (p = 0.004). Survival appears also to be influenced by elevated LDH serum levels (p = 0.011), and age >65 yr (p = 0.014). Large cooperative randomized studies are needed to clarify the role of adriamycin in the chemotherapy of CCL, a disease which at present has no established standard treatment.
