Newly Diagnosed Childhood Acute Lymphoblastic Leukemia (Standard Risk)
Treatment of standard-risk childhood acute lymphoblastic leukemia (ALL) during the induction, consolidation /intensification, and maintenance phases may include...
Patients with early unfavorable HL showed relapse rates over 30% at 5 years with radiation therapy alone, prompting evaluation of chemotherapy plus involved-field radiation therapy (IF-XRT) versus chemotherapy alone. The late mortality from solid tumors, especially in the lung, breast, gastrointestinal tract, and connective tissue, and from cardiovascular disease makes radiation therapy a less attractive option unless therapeutic benefits exceed the long-term complications.[2,3,4,5,6]
A randomized, prospective trial from the National Cancer Institute of Canada involving 276 patients with early unfavorable HL compared ABVD for four to six cycles to ABVD for two cycles plus extended-field radiation therapy (EF-XRT); with a median follow-up of 11.3 years, the freedom-from-progression favored combined modality therapy (86% vs. 94%; P = .006), but the overall survival was better for ABVD alone (92% vs. 81%; P = .04).[Level of evidence: 1iiA] The trend toward a worse survival for the combined modality arm was attributed to excess secondary malignancies and cardiovascular deaths. In this trial, the extended-field radiation used higher doses and significantly larger exposure to body sites than are employed in current practice.
A randomized study from the Southwest Oncology Group of clinically staged patients (no laparotomy) compared subtotal lymphoid radiation to 3 months of AV followed by subtotal lymphoid radiation therapy; the combined modality arm showed superior failure-free survival (94% vs. 81%; P < .001) but not OS at 3.3 years' median follow-up.[Level of evidence: 1iiDiii]
In a randomized study from the Milan Cancer Institute of patients with clinical early-stage Hodgkin lymphoma, 4 months of ABVD followed by either IF-XRT or EF-XRT showed similar OS and freedom-from-progression with 10 years' median follow-up, but the study had inadequate statistical power to determine noninferiority of IF-XRT versus EF-XRT.[Level of evidence: 1iiDii] Similarly, in a randomized study from the German Hodgkin Lymphoma Study Group (GHSG) of more than 1,000 patients with early unfavorable HL, 4 months of COPP plus ABVD followed by IF-XRT versus EF-XRT showed equivalent OS and freedom-from-treatment failure (FFTF) with 5 years' median follow-up.[Level of evidence: 1iiA] Another randomized study of 996 patients with early unfavorable HL also showed no difference in OS and event-free survival at 10 years comparing four to six cycles of MOPP-ABV plus IF-XRT versus the same chemotherapy plus subtotal nodal radiation therapy.[Level of evidence: 1iiA]
