Discontinuation of combo immunotherapy and outcome of patients with melanoma brain metastases.
Article in Journal for immunotherapy of cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundNivolumab plus ipilimumab (COMBO) is the standard treatment for asymptomatic melanoma brain metastases (MBM), but current guidelines do not provide specific recommendations for treatment discontinuation in responding patients. This study aimed to evaluate outcomes after COMBO discontinuation within 24 months and the role of continuing treatment beyond 24 months.
methodsPatients with MBM treated with COMBO who discontinued treatment within 24 months for reasons other than disease progression or continued beyond this time point were retrieved. Overall survival (OS), objective response, progression-free survival (PFS) and toxicities were analyzed.
results465 patients were included: 392 discontinued COMBO within 24 months, while 73 continued beyond 24 months. Treatment was discontinued due to complete response (CR, n=47), partial response (PR, n=45), stable disease (SD, n=12), toxicity after SD (n=59), toxicity after CR (n=99), or toxicity after PR (n=130). At multivariable analysis, the line of treatment (>first vs first: HR 2.65 (1.62-4.32)), the immune-related adverse events (irrespective of anti-tumor necrosis factor-alpha) (HR 0.18 (0.07-0.42)); COMBO discontinuation after CR (HR 0.15 (0.05-0.40)), or PR (HR 0.08 (0.03-0.26)), as well as stopping due to toxicity after CR (HR 0.14 (0.07-0.27)) or PR (HR 0.51 (0.32-0.82)), were associated with OS. Notably, at a median follow-up of 51 months (IQR 31-70), patients with CR/PR who discontinued COMBO within 24 months had PFS and OS comparable to those who continued treatment beyond this time point. 4-year OS exceeded 83% in patients discontinuing COMBO after CR, PR, or toxicity following CR, compared with 66.4% in those discontinuing due to toxicity after PR; median PFS was not reached in the former groups but was 18.6 months in the toxicity after PR group.
conclusionDiscontinuation of COMBO within 24 months appears safe in patients with CR and in selected cases of PR, with no survival disadvantage versus prolonged therapy.
