A large-scale clinicopathological and long-term follow-up study of solid papillary carcinoma of the breast.

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
Solid papillary carcinoma of the breast (SPC) is a rare tumor of the breast with the unique histology and frequent neuroendocrine differentiation. However, a real nature and diagnostic importance of the neuroendocrine differentiation have not been properly handled. And relationship between SPC and the other types of invasive breast carcinoma, especially neuroendocrine tumor of the breast (NETb), has not been fully explained. We conducted a clinicopathological study of SPC to tackle these problems.In the study, we included 127 cases of SPC with long-term follow-ups of up to 30 years. The incidence in the breast carcinoma was 2.0%. The patients with SPC had a significantly better prognosis and no patients died of the tumor. The 35 cases had only SPC in situ (SPC-IS), while the 92 cases had both SPC-IS and SPC with invasion (SPC-INV). Immunohistochemically, 123 of the 127 cases exhibited diffuse expression of one or more neuroendocrine markers. Fifty of the 92 cases had exclusively invasive SPC (iSPC) as the invasive component. Twenty-two cases of iSPC were combined with NETb and the 18 cases with MUC. Six of 8 cases with metastatic SPC-INV disclosed iSPC in the axillary lymph node.This study suggests that SPC is immunohistochemically compatible with NET of the systemic organs (NETs). And the unique morphology of SPC may represent a traditional histology of NETs. The study also indicates that SPC has close relationship between NETb and type B MUC. And SPC and NETb may represent a spectrum of the same disease.
