Race as a prognostic factor of breast mucinous carcinoma.
Article in Journal of cancer research and clinical oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThe rarity of breast mucinous carcinoma (BMC) makes it challenging to study the prognosis of this disease across diverse racial populations. This study aimed to leverage epidemiological data on immigrant populations to elucidate the prognostic differences in BMC patients from various racial/ethnic backgrounds. The goal was to help formulate more personalized clinical practice guidelines for the management of this rare malignancy.
methodsThe study included 208 BMC patients from China and 10,322 BMC patients from the SEER database. Clinicopathological data, treatment information, and survival outcomes were compared across different racial/ethnic groups using statistical analyses.
resultsAsian American BMC patients were younger at diagnosis and had more favorable tumor grade and stage compared to other racial groups. After adjusting for clinicopathological factors and treatments, Asian American BMC patients exhibited significantly better overall survival (OS) than black (HR = 1.53, 95% CI: 1.05-2.22, P = 0.027) and white patients (HR = 1.41, 95% CI: 1.03-1.94, P < 0.001). Specifically, non-Chinese American patients had a worse OS compared to Chinese patients (adjusted HR = 2.59, 95% CI: 1.15-5.83, P = 0.022). Chemotherapy significantly improved OS only in black BMC patients (adjusted HR = 0.52, 95% CI: 0.27-0.98, p = 0.045), but not in other racial/ethnic groups.
conclusionRace is an independent prognostic factor for BMC. Compared with Chinese patients, black and white American patients have a worse prognosis in terms of OS. Treatment guidelines for BMC patients should be formulated with considerations of race factors. For patients with BMC originating from China, a more conservative treatment approach may be warranted.
