Outcomes of patients with HER2-negative metastatic breast cancer after platinum- and non-platinum-based first-line chemotherapy among patients with and without pathogenic germline BRCA1/2 mutations.
Trial report in British journal of cancer, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03275311 (Epidemiological Strategy and Medical Economic), which is not on this map. Cited by 2 papers.
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.

Abstract
backgroundThe efficacy and added benefit of platinum-based chemotherapy (PtCT) for metastatic breast cancer (MBC) remain unclear in patients with and without germline BRCA1 or BRCA2 mutations (gBRCA1/2m and gBRCA1/2wt, respectively).
methodsWe selected from the French national real-world multicentre ESME cohort (2008-2016) all patients with HER2-negative MBC with known gBRCA1/2 status at first-line chemotherapy initiation. Using multivariable Cox models, we compared the outcome (progression-free (PFS) and overall survival (OS)) of first-line PtCT and non-PtCT regimens based on the patients' gBRCA1/2 status and tumour subtype.
resultsPatients who received PtCT had more aggressive tumour features. In the multivariable analysis, first-line PtCT was associated with better adjusted PFS and OS in gBRCA1/2m carriers (N = 300), compared with non-PtCT (HR 0.54, 95% CI 0.4-0.73, P < 0.001, and HR 0.70, 95% CI 0.49-0.99, P = 0.047, respectively). Conversely, outcomes were similar in gBRCA1/2wt patients (N = 922) treated with PtCT and non-PtCT, whatever the tumour subtype. Landmark analyses at months 3 and 6 post treatment initiation supported these results.
conclusionsIn this pre-PARP inhibitor real-world cohort, PFS and OS were better after PtCT than non-PtCT in patients with gBRCA1/2m, but not in those with gBRCA1/2wt. These results emphasise the need of early gBRCA1/2 testing in patients with MBC. CLINICAL TRIAL NUMBER: NCT03275311.
