The Role of Tumor-Associated Neutrophils in Early Luminal HER2-Negative Breast Cancer Progression.
Article in Asian Pacific journal of cancer prevention : APJCP, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectivesTo study the predictive role of tumor-associated neutrophils in early luminal HER2-negative breast cancer. MATERIALS AND
methodsThis is a retrospective study conducted on 60 women cases aged from 31 to 79 years underwent surgery for luminal HER2-negative ductal breast cancer in tertiary care cancer centre. We first estimated basic morphological signs: tumor size, tumor grade (by Nottingham Histologic Score), tumor infiltrating lymphocytes (TILs), Lymphovascular invasion, hormonal receptors status, proliferative index, and regional lymph nodes metastasis. The expression of intratumoral neutrophils was studied by CD15 immunohistochemistry which was performed using tissue microarrays. The total number of intratumoral neutrophils, were counted in 5 high-power fields.
resultsAccording to the Nottingham histologic score system, grade I cases were detected in 10 cases (16%), grade II in 34 cases (57%), and grade III in 16 cases (27%). Lymphovascular invasion was determined in 23 cases (38%), and perineural invasion in 14 cases (23%). Number of TILs varied from 0 to 14 (counted in 5 HPF) and averaged 4.2±0.5. Luminal A tumor phenotype was detected in 35 cases (58%), and luminal B HER2-negative in 25 cases (42%). Nineteen (32%) women had metastases in regional lymph nodes (N+). The number of tumor microenvironment neutrophils in luminal HER2-negative breast carcinomas ranged from 1 to 10 (counted in 5 HPF) with an average value of 2.7±0.4. High tumor-associated neutrophils concentration significantly correlated with tumor size (<5mm and >20mm) with p=0.05, high grade (p=0.01), high proliferative index ((r=0.67; p=0.05), TILs (p=0.05), Lymphovascular space invasion (p=0.01)and positive regional lymph nodes metastasis (p=0.001), but not perineural invasion (p=0.1) and also, did not correlate with the expression of estrogen (r=0.18) and progesterone (r=0.14) receptors.
conclusionTumor-associated neutrophils strongly predict a worse prognosis in early luminal HER2-negative breast cancer.
