1 · What the graph read from it

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.

2 · The registry

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

purposePalliative treatment options for HR + HER2- advanced breast cancer (ABC) patients have increased, but data is lacking about the optimal treatment sequence. We used real-world data from a comprehensive cancer center to describe applied treatment sequences and we determined treatment-related and survival outcomes.

methodsPatients aged 18 years and older with HR + HER2- ABC treated with systemic treatment were included in this historic cohort study. Sequential treatment schedules, time to treatment discontinuation, time to chemotherapy, and overall survival (OS) were determined, stratified by first-line treatment.

results202 patients were included. They received a total of 650 treatment lines (median 3; range: 1-11). 91 (45%), 25 (12%), 24 (12%), 28 (14%), 22 (11%) and 12 (6%) patients started first-line treatment with non-steroidal aromatase inhibitors (NSAI), NSAI + cyclin dependent kinase 4/6-inhibitors (CDK4/6i), fulvestrant + CDK4/6i, tamoxifen, chemotherapy and other treatment, respectively. 10, 13, and 14 different treatment regimens were given in first, second and third-line, respectively. Of the patients who started first-line NSAI monotherapy (n = 91), 3 (3%) died before receiving second-line treatment.

conclusionIn this real-world cohort, we observed a wide variety of different treatment sequences applied in daily clinical practice, some of which were in discordance with the current guidelines. Fear that patients may never get around to treatment with CDK4/6i if a patient did not start with a CDK4/6i was not supported by our study results.
