    • Background: Our aims were to evaluate the response to salvage treatment in relation to initial treatment and to evaluate prognostic factors at the time of relapse in an unselected population of relapsing patients with Hodgkin's lymphoma (HL). Patients and methods: In total, 124 patients younger than 60 yr of age with initial diagnosis of HL in Sweden relapsed between 1985 and 1995. Results: Fifty-eight patients relapsed after initial treatment with radiotherapy (RT) only, 62 after combination chemotherapy (CT), of whom 30 had received additional involved-field RT, and four after a short course of CT followed by extended-field RT. For 37 patients among the 58 relapsers after initial RT treated according to the recommendations of the National guidelines, the 5-yr Hodgkin-specific survival (HLS) was 85%, overall survival (OS) 73% and event-free survival (EFS) 62%, which is not inferior to survival in patients with primarily advanced stages. It was poorer in the 21 patients who initially had received RT only, even though they had been recommended for more extensive treatment. For patients initially treated with a full course (6-8 cycles) of CT the 5-yr HLS was 60%, OS 58% and EFS 22%. Bulky disease and age at diagnosis strongly affected survival in a multivariate analysis. Conclusions: Patients initially treated with RT who relapse have a favourable outcome, provided they have been treated according to the recommendations of the guidelines at the time of diagnosis. Initially bulky disease and, as a consequence, additional RT as part of the initial treatment negatively affect survival at relapse in patients initially treated with a full course of CT.

  • Relapsed Hodgkin's lymphoma : immunostaining patterns in relation to survival
  • 2002

    • Patients with relapsing Hodgkin's lymphoma (HL) have a rather poor prognosis and mechanisms that lead to resistance to therapy are poorly understood. Our aims were to investigate the immunohistochemical staining patterns of Rb (retinoblastoma protein) and the p53 tumour suppressor protein in HL at initial presentation and at relapse in order to elucidate a possible role in disease progression and resistance to therapy. Further to evaluate the presence and prognostic importance of Epstein-Barr virus (EBV) and anaplastic lymphoma kinase (ALK). Eighty-one cases of relapsing HL were reexamined histopathologically and immunostained for the expression of p53, Rb, ALK and CD30. EBV was detected with LMP-1 stainings and in situ hybridisation for EBER. Clinical data were extracted from the Swedish National Health Care Programme for HL. Median follow-up time was six years (range 0-12) from the date of relapse. The majority of cases were positive for p53 and Rb both at presentation and at relapse, though to a different extent. Both an increase and a decrease in the proportion of stained tumour cells were observed. None of our cases was ALK-positive and 44% were EBV-positive. No specific staining pattern was directly correlated to survival. In 12 patients a switch in HL subtype from diagnosis to relapse was observed and the five-year Hodgkin-specific survival (HLS) was statistically significantly inferior, 37 vs 81% (p = 0.002), in those patients. We found a significant relation between the expression of p53 and EBV at diagnosis and relapse, indicating a clonal relationship. We were unable to find any specific staining pattern of p53 or Rb, affecting survival.
