PURPOSE: Despite multiple randomized trials, variation in practice remains regarding the most effective treatment for early-stage, favorable-risk Hodgkin lymphoma. With increasing emphasis on alternative payment models, we investigate the cost-effectiveness of chemotherapy alone versus combined modality therapy (CMT).
METHODS AND MATERIALS: A Markov model was formed to compared 2 cycles of adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) to 2 cycles of ABVD followed by 20 Gy in 10 fractions involved-site radiation therapy. Modalities were compared using the incremental cost-effectiveness ratio, with effectiveness measured in quality-adjusted life years (QALYs) and evaluated with a willingness to pay a threshold of $100,000 per QALY gained.
RESULTS: The base case analysis showed that CMT is cost-effective compared with ABVD alone, with an incremental cost-effectiveness ratio of $8028 per QALY gained and an incremental cost of $236 gaining 0.029 QALYs. On sensitivity analyses, the results were the most sensitive to changes in recurrence rates. If the recurrence rate differences were ≥6%, CMT was cost-effective.
CONCLUSIONS: CMT is a cost-effective strategy for early-stage, favorable-risk Hodgkin lymphoma based on currently available evidence. However, small variations in recurrence-rate estimates dramatically affect strategy cost-effectiveness.
