Can We Forgo Sentinel Lymph Node Biopsy in Women Aged ≥ 50 Years with Early-Stage Hormone-Receptor-Positive HER2-Negative Special Histologic Subtype Breast Cancer?
Article in Annals of surgical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundBreast cancer has significant biologic heterogeneity, which influences treatment decisions. We hypothesized that in postmenopausal women (≥ 50 years) with clinical T1-2, N0, hormone receptor positive (HR+), HER2 negative (HER2-) breast cancer of special histology (mucinous, tubular, cribriform, papillary), information from sentinel lymph node biopsy (SLNB) may not change adjuvant therapy recommendations. PATIENTS AND
methodsWe constructed a cohort from the National Cancer Database of women aged ≥ 18 years with cT1-2 N0 HR+ HER2- invasive breast cancer. We calculated the frequency of nodal positivity by histology. We measured the frequency of N2/N3 disease, the distribution of Oncotype DX 21-gene assay recurrence score (ODX RS) across special histology by nodal status, and frequency of chemotherapy use by ODX RS and pathologic N stage.
resultsIn women with cN0 HR+/HER2- special histologic subtype breast cancer, the likelihood of pathologic nodal positivity is less than 5%, and 99.7% of patients had N0 or N1 disease. Among women aged ≥ 50 years with HR+/HER2- special histologic subtype breast cancer, there was low prevalence of high ODX RS > 25 in both N0 and N1 patients (7% overall). Receipt of chemotherapy correlated with Oncotype DX scores as anticipated, with the lowest use in women with a low/intermediate RS (from 2 to 6% for N0 and 6-24% for N1) and the highest use in women with high risk Oncotype scores (from 74 to 92%).
conclusionsOur study suggests that SLNB could potentially be omitted in select postmenopausal women with cT1-2 N0 HR+/HER2- special histologic subtype breast cancer when ODX RS is available.
