Adjuvant atezolizumab can prevent recurrence and death in patients with early non-small cell lung cancer (NSCLC) and therefore reduce costs of care, according to a study presented at JADPRO Live 2022, the annual APSHO meeting.
The study included US adults with resected, stage II-IIIA NSCLC who had PD-L1 levels of 1% or greater.
Researchers calculated the cumulative number of recurrences and deaths prevented, life-years saved, and associated cost reductions that would occur over a 5-year period if patients were treated with adjuvant atezolizumab rather than best supportive care.
The base case analysis included 4361 patients, and 2396 of them had a recurrence within 5 years when treated with best supportive care.
The researchers calculated that if these 4361 patients received atezolizumab, a mean 1027 patients would avoid disease recurrence over 5 years. Atezolizumab would also prevent a mean 373 deaths over that period, which translates to a mean 830.04 life-years saved.
The reduction in recurrences and deaths would lead to a mean $781 million reduction in cumulative direct costs, a mean $15.5 million reduction in indirect costs, and a mean $32.4 million reduction in terminal costs over 5 years, the researchers calculated.
They concluded that atezolizumab could “prevent a significant number of recurrence events and prolong overall survival, with important clinical, humanistic, and economic consequences for patients, physicians, payers, and society.”
