Budget impact analysis of neoadjuvant nivolumab for non-small cell lung cancer in the Chilean public healthcare system: An exploratory economic assessment.
Article in Clinical & translational oncology : official publication of the Federation of Spanish Oncology Societies and of the National Cancer Institute of Mexico, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeEffective and sustainable treatments to improve patient outcomes are urgently needed for non-small cell lung carcinoma (NSCLC). Neoadjuvant therapies, particularly nivolumab, have shown superior outcomes in event-free survival and pathological response, yet financial coverage is scarce. We aim to provide an exploratory economic analysis to assess the implications of its incorporation into routine clinical practice.
methodsWe conducted a six-step BIA (budget impact analysis) based on a decision tree model for pathways, probabilities, and resource utilization from the national payer perspective at an event-free survival (EFS) horizon. We estimated the direct cost of drugs and all healthcare-related services for two scenarios: a baseline scenario [neoadjuvant chemotherapy (CT)] and an alternative scenario [neoadjuvant nivolumab combined with chemotherapy (N + CT)].
resultsThe funnel-down technique determined 359 eligible patients nationwide per year. The total cost of treatment in the baseline scenario amounts to CLP $ 7315 million Chilean pesos (€ 8,063,219) per cohort, with three top cost drivers: 1L drugs after recurrence (51.98%), resection (29.33%) and 2L nivolumab (5.85%). The alternative scenario amounted to CLP $ 6853 million (€ 7,553,572), with the highest relative expenditure attributed to the N + CT scheme (61.76%), resection (31.31%), and follow-up (2.73%). Adjuvant costs decrease to 1.03%, as does the expenditure on 1L (51.98% versus 0.34%) and 2L treatments (5.85% versus 0.18%). Early intervention in NSCLC reduces the budgetary impact by 6.3% (savings of - $ 462 million (€ 509,647) per treated cohort).
conclusionsEarly incorporation of N + CT optimizes healthcare expenditure by providing access to therapies that improve survival rates while reducing the need for costly treatments in advanced stages. This approach represents a dominant strategy.
