We reviewed 45 cases of Waldeyer's ring lymphomas (25 stage IE, 20 IIE): 73% had high-grade histology according to Kiel's classification. Fourteen patients received radiotherapy alone and 31 chemotherapy, combined with radiotherapy in 28. Complete remission rate was 95% and relapse rate 32%. At 8 years overall disease-related survival (DRS) and event-free survival (EFS) were 69% and 57% respectively. Combined treatment provided both significantly better DRS (82% vs 42%) and EFS (76% vs 25%) than radiotherapy alone. Most of the patients with high-grade histology (26/33) received the combined treatment and this subgroup achieved a long-term EFS of 78%. Both DRS and EFS were also significantly longer in patients under 60. At multivariate analysis favorable prognostic factors were lower age for DRS and combined treatment for EFS.

Abstract

We reviewed 45 cases of Waldeyer's ring lymphomas (25 stage IE, 20 IIE): 73% had high-grade histology according to Kiel's classification. Fourteen patients received radiotherapy alone and 31 chemotherapy, combined with radiotherapy in 28. Complete remission rate was 95% and relapse rate 32%. At 8 years overall disease-related survival (DRS) and event-free survival (EFS) were 69% and 57% respectively. Combined treatment provided both significantly better DRS (82% vs 42%) and EFS (76% vs 25%) than radiotherapy alone. Most of the patients with high-grade histology (26/33) received the combined treatment and this subgroup achieved a long-term EFS of 78%. Both DRS and EFS were also significantly longer in patients under 60. At multivariate analysis favorable prognostic factors were lower age for DRS and combined treatment for EFS.
