Prognostic factors for subdiaphragmatic involvement in clinical stage I–II supradiaphragmatic Hodgkin’s disease: A retrospective analysis of the GHSG

PURPOSE: To evaluate mantle radiotherapy (MRT) alone as the initial therapy of patients with clinical stage (CS) I-II Hodgkin's disease (HD). PATIENTS AND METHODS: We performed a retrospective study of patients treated with MRT alone for CS I-II supradiaphragmatic HD between 1969 and 1994. Prognostic factor analysis was performed for progression-free survival (PFS) and overall survival (OS). Outcome was also assessed in favorable cohorts defined in the literature. RESULTS: There were 261 eligible patients. The median follow-up period for surviving patients was 8.4 years (range, 1.8 to 27.4 years). The 10-year OS rate was 73%. Multifactor analysis for OS showed that age was the only important prognostic factor. The 10-year PFS rate was 58%. On multifactor analysis for PFS, the most important prognostic factors were clinical stage, B symptoms, histology, number of sites, and tumor bulk. The 10-year PFS rate for lymphocyte-predominant disease was 81% for stage I and 78% for stage II. In favorable patient cohorts defined in the literature, the 10-year PFS rate ranged from 70% to 73% for the whole group and from 71% to 90% in patients with favorable stage I disease, but only from 48% to 57% in patients with favorable stage II disease. On competing-risks analysis, the cumulative 10-year incidence of first site of failure in the para-aortic/splenic region alone was 10.5%. Sixty percent of relapsed patients remain progression-free at 10 years after chemotherapy salvage. CONCLUSION: These results support the use of MRT alone in patients with favorable CS I HD and CS I-II HD with lymphocyte-predominant histology. The remainder of patients with CS I-II HD require more intensive treatment.

PURPOSE: To determine the efficacy of mantle radiation therapy alone in selected patients with early-stage Hodgkin’s disease. PATIENTS AND METHODS: Between October 1988 and June 2000, 87 selected patients with pathologic stage (PS) IA to IIA or clinical stage (CS) IA Hodgkin’s disease were entered onto a single-arm prospective trial of treatment with mantle irradiation alone. Eighty-three of 87 patients had ≥ 1 year of follow-up after completion of mantle irradiation and were included for analysis in this study. Thirty-seven patients had PS IA, 40 had PS IIA, and six had CS IA disease. Histologic distribution was as follows: nodular sclerosis (n = 64), lymphocyte predominant (n = 15), mixed cellularity (n = 3), and unclassified (n = 1). Median follow-up time was 61 months. RESULTS: The 5-year actuarial rates of freedom from treatment failure (FFTF) and overall survival were 86% and 100%, respectively. Eleven of 83 patients relapsed at a median time of 27 months. Nine of the 11 relapses contained at least a component below the diaphragm. All 11 patients who developed recurrent disease were alive without evidence of Hodgkin’s disease at the time of last follow-up. The 5-year FFTF in the 43 stage I patients was 92% compared with 78% in the 40 stage II patients (P = .04). Significant differences in FFTF were not seen by histology (P = .26) or by European Organization for Research and Treatment of Cancer H-5F eligibility (P = .25). CONCLUSION: Mantle irradiation alone in selected patients with early-stage Hodgkin’s disease is associated with disease control rates comparable to those seen with extended field irradiation. The FFTF is especially favorable among stage I patients.

The H5 program in clinical stage (CS) I to II supradiaphragmatic Hodgkin's disease (HD) was tailored to prognostic factors identified in former European Organization for the Research and Treatment of Cancer (EORTC) studies. Among the 494 adult patients included in the study, the 237 patients belonging to the favorable group (H5F) underwent a staging laparotomy (Sx) in order to select the patients who could be treated with limited radiotherapy (RT) only. Thus, 198 patients (84%) with negative laparotomy were treated with RT alone and randomized to either mantle irradiation (M) or extended field mantle plus para-aortic (M + PA) irradiation. Complete remission (CR) was achieved in 99% of the patients. There was no difference in the 6-year relapse-free survival (RFS) rate (74% and 72%, respectively) or survival rate (96% and 89%). Therefore, Sx helped to define those patients who could be treated with M alone in contrast to those who required more aggressive therapy. The 39 patients with positive laparotomy were treated as the unfavorable group (H5U) from onset and randomized to either total/subtotal nodal irradiation (TNI/STNI) or a sandwiched mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) X 3, M irradiation, MOPP X 3 protocol (3M). Although the RFS rate was higher in the 3M arm (100% v 53%; P = .002), the 6-year survival was not significantly different between the two arms (overall, 92%). In the 257 patients with initial unfavorable disease, the Sx was avoided. They were randomized to either TNI/STNI or 3M. In complete responders (96%), the 6-year RFS was 91% in the 3M arm and 77% in the TNI/STNI arm (P = .02). The pattern of failure differed in the two arms: the inverted Y and spleen irradiation controlled occult infradiaphragmatic disease better than MOPP; conversely, less patients begun on MOPP recurred in the involved mantle areas. The difference in 6-year actuarial total survival (TS) (89% and 82%; P = .05 in favor of the 3M arm) was not retrieved after exclusion of the unrelated deaths from the analysis. The two arms produced similar TS in patients under 40 years of age. TNI retains interest, especially in young men wishing to preserve fertility. The overall result shows that when treatment is tailored to initial prognostic factors, excellent results can be obtained in all patient subgroups at minimal morbidity and toxic cost.
