The Role of Radiation Therapy in Addition to Lumpectomy and Hormone Therapy in Men 70 Years of Age and Older with Early Breast Cancer: A NCDB Analysis.
Article in Annals of surgical oncology, 2021. 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
purposeCurrent treatment guidelines for male breast cancer are guided by female-only trials despite data suggesting distinct clinicopathologic differences between sexes. We sought to evaluate whether radiation therapy (RT) after lumpectomy was associated with equivalent survival among men > 70 years of age with stage I, estrogen receptor (ER) positive tumors, as seen in women from the Cancer and Leukemia Group B (CALGB) 9343 trial.
methodsWe performed a retrospective analysis of 752 stage I, ER-positive male breast cancer patients ≥ 70 years who were treated with hormone therapy and surgery, with or without RT, from the National Cancer Database between 2004 and 2014. Patients were categorized based on surgery and RT (lumpectomy alone, lumpectomy with RT, and mastectomy alone). Multivariable Cox proportional hazards regression analysis was used to compare overall survival between treatment groups.
resultsMost patients underwent total mastectomy, with only 32.6% treated with lumpectomy. Of those who underwent lumpectomy, 72.7% received adjuvant RT. In multivariate analysis, there was no statistical difference in overall survival when comparing lumpectomy alone and lumpectomy with RT (aHR 0.72 [95% CI 0.38-1.37], p = 0.31) or when comparing lumpectomy (alone or with RT) and mastectomy (aHR 1.28 [95% CI 0.88-1.87], p = 0.20).
conclusionsIn this national sample of elderly men with ER-positive early-stage disease treated with endocrine therapy, there were no significant differences in overall survival when comparing lumpectomy alone and lumpectomy with RT, or lumpectomy (alone or with RT) and mastectomy. These results suggest that less aggressive treatment may be appropriate for a subset of male breast cancer patients.
