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

objectiveMirvetuximab soravtansine may be a potentially effective therapeutic option for ovarian low-grade serous carcinoma (LGSC), but the prevalence of folate receptor alpha (FRα) overexpression in this tumor type is unknown. We sought to characterize FRα expression in LGSC and its association with clinical and molecular features.

methodsFRα immunohistochemistry was performed on a tissue microarray comprised of 89 LGSCs and 42 ovarian serous borderline tumors (SBTs). Clinical tumor-normal panel-based sequencing was performed on 78 LGSCs. Associations between FRα-high status and clinicopathologic characteristics and survival outcomes were examined.

resultsOf 89 LGSCs, 36 (40%) were FRα-high (≥75% of viable tumor cells exhibiting moderate-to-strong membranous expression). Of 9 patients with LGSC and samples from different timepoints, 4 (44%) had discordant results, with conversion from FRα-negative to FRα-high in 3 (33%) cases. There was no association between FRα-high status with age, race, or progression-free/overall survival. A MAPK pathway genetic alteration, most commonly involving KRAS (n = 23), was present in 45 (58%) LGSCs. Those lacking MAPK pathway alterations were more likely to be FRα-high compared to MAPK-altered LGSCs (61% vs 20%, p < 0.001). In SBTs, FRα-high expression was associated with high-risk (micropapillary) histology and/or subsequent LGSC recurrence compared to conventional SBTs without malignant recurrence (53% vs 9%, p = 0.008).

conclusionsFuture studies of FRα-directed therapy in patients with LGSC are warranted. Discordant FRα status at recurrence suggests potential benefit for retesting. A biomarker-driven approach to direct treatment selection in LGSC is recommended. As high FRα expression is more common amongst tumors lacking MAPK pathway genetic alterations, FRα testing to determine eligibility for mirvetuximab soravtansine therapy is particularly recommended for this subgroup.
