PURPOSETo investigate the role of consolidation radiotherapy (cRT) in advanced-stage Hodgkin lymphoma (HL) presenting at baseline with a large nodal mass (LNM) in complete metabolic response after doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy.PATIENTS AND METHODSAdvanced-stage (IIB-IVB) HL patients, enrolled in the HD 0607 trial (Clinicaltrial.gov identifier NCT00795613), with both a negative PET after two (PET-2) and six (PET-6) ABVD cycles, who presented at baseline with an LNM, defined as a nodal mass with the largest diameter >= 5 cm, were prospectively randomly assigned to receive cRT over the LNM or no further treatment (NFT).RESULTSAmong 296 randomly assigned patients, the largest diameter of LNM at baseline was 5-7 cm in 101 (34%; subgroup A) and 8-10 cm in 96 (32%; subgroup B), whereas classic bulky (diameter > 10 cm) was detected in 99 (33%; subgroup C). Two hundred eighty patients (88%) showed a postchemotherapy RM. The median dose of cRT was 30.6 Gy (range, 24-36 Gy). After a median follow-up of 5.9 years (range, 0.5-10 years), the 6-year progression-free survival rate of patients who underwent cRT or NFT was, respectively, 91% (95% CI, 84% to 99%) and 95% (95% CI, 89% to 100%; P = .62) in subgroup A; 98% (95% CI, 93% to 100%) and 90% (95% CI, 80% to 100%; P = .24) in subgroup B; 89% (95% CI, 81% to 98%) and 86% (95% CI, 77% to 96%; P = .53) in subgroup C (classic bulky).CONCLUSIONcRT could be safely omitted in patients with HL presenting with an LNM and a negative PET-2 and PET-6 scan, irrespective from the LNM size detected at baseline.

Abstract

PURPOSETo investigate the role of consolidation radiotherapy (cRT) in advanced-stage Hodgkin lymphoma (HL) presenting at baseline with a large nodal mass (LNM) in complete metabolic response after doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy.PATIENTS AND METHODSAdvanced-stage (IIB-IVB) HL patients, enrolled in the HD 0607 trial (Clinicaltrial.gov identifier NCT00795613), with both a negative PET after two (PET-2) and six (PET-6) ABVD cycles, who presented at baseline with an LNM, defined as a nodal mass with the largest diameter >= 5 cm, were prospectively randomly assigned to receive cRT over the LNM or no further treatment (NFT).RESULTSAmong 296 randomly assigned patients, the largest diameter of LNM at baseline was 5-7 cm in 101 (34%; subgroup A) and 8-10 cm in 96 (32%; subgroup B), whereas classic bulky (diameter > 10 cm) was detected in 99 (33%; subgroup C). Two hundred eighty patients (88%) showed a postchemotherapy RM. The median dose of cRT was 30.6 Gy (range, 24-36 Gy). After a median follow-up of 5.9 years (range, 0.5-10 years), the 6-year progression-free survival rate of patients who underwent cRT or NFT was, respectively, 91% (95% CI, 84% to 99%) and 95% (95% CI, 89% to 100%; P = .62) in subgroup A; 98% (95% CI, 93% to 100%) and 90% (95% CI, 80% to 100%; P = .24) in subgroup B; 89% (95% CI, 81% to 98%) and 86% (95% CI, 77% to 96%; P = .53) in subgroup C (classic bulky).CONCLUSIONcRT could be safely omitted in patients with HL presenting with an LNM and a negative PET-2 and PET-6 scan, irrespective from the LNM size detected at baseline.
