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

Metastasis of invasive ductal carcinoma of the breast to the uterine cervix is rare, with only one report of a case occurring more than 20 years after the primary surgery. A 69-year-old woman presented with abnormal uterine cervical cytology (atypical glandular cells without tumor diathesis) 30 years after undergoing breast cancer surgery. Magnetic resonance imaging revealed a 38-mm cervical mass. Modified radical hysterectomy was performed. The resected specimen exhibited an immunohistochemical profile of GATA3(+)/mammaglobin(+)/PAX8(-), which definitively excluded primary cervical adenocarcinoma and confirmed the diagnosis of metastatic invasive ductal carcinoma. Crucially, although the primary tumor was hormone receptor-positive, cervical metastasis exhibited receptor conversion to HER2-positive status. This case underscores the importance of considering metastatic breast cancer in the differential diagnosis of cervical masses in breast cancer survivors regardless of the disease-free interval. This further highlights the necessity for receptor re-evaluation in metastatic lesions to guide appropriate targeted therapy.
