Ureteral metastasis from a HER2-enriched breast cancer: a rare case report.
Article in Translational cancer research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Ureteral metastasis from breast cancer (BC) is very rare, and only a few cases have been reported. We report the first patient with ureteral involvement from human epidermal receptor 2 (HER2) enriched metastatic BC. A 51-year-old woman with HER2-enriched metastatic BC with liver metastasis was diagnosed at her first visit, achieving complete tumor regression by chemotherapy, anti-HER2 treatment, modified mastectomy and radiotherapy. After 1 year, she complained light left flank pain for 1 month, with an elevated cancer antigen 15-3 (CA15-3) level in blood. Computed tomography showed a left proximal ureteral lesion causing ureterectasis and hydronephrosis. A ureteroscope-guided biopsy of the ureteral lesion revealed poorly differentiated carcinoma from metastatic BC. Diagnosing ureter metastasis from BC were established by histopathology and immunohistochemistry. The flank pain and ureteral lesion were absolutely relieved after chemotherapy and anti-HER2 treatment, and CA15-3 level decreased to normal. Regular follow-up examinations every 3 months are performed at our outpatient clinic. With a 20 months follow-up, there has been no further progression up to now. Ureteral metastasis of BC shows nonspecific symptoms, and it is important to recognize this unusual manifestation so that timely appropriate treatment can be initiated in order to better prognosis. Chemotherapy plus anti-HER2 treatment are most effective for hepatic and ureteral metastasis from BC.
