Modeling effective tumor burden of primary lesion and metastatic lymph node in breast cancer patients from the SEER database.
Article in Gland surgery, 2022. 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
backgroundCharacterizing the role of the primary tumor and axillary lymph nodes (ALNs) in metastasis progression can provide a rational basis for effective local control and systemic treatments.
methodsWe employed data from the Surveillance, Epidemiology, and End Results (SEER) database to perform survival analysis and modeling to estimate breast cancer (BC) progression in both untreated and treated patients. Effective tumor burden was defined as the number of cancer cells that can lead to distant metastasis. Quantified analysis was conducted for primary lesion and metastatic nodes, respectively. A tumor growth model was built based on mathematical modeling:
resultsWe found that both the primary lesion and the metastatic LNs contribute to the effective tumor burden. Through fitting the built tumor growth model, "m" in treated groups was determined to be 1, and "n" was determined to be 1.5; while in the untreated group, "m" was determined to be 1, and "n" was 0.15, which was 10 times smaller than in treated groups.
conclusionsOur study revealed that the prognostic value of the anatomic stage in BC progression varied in different historical periods, due to the development of oncological treatments. While tumor size was a significant prognostic factor in both untreated and treated patients, the prognostic value of nodal status was only significant in patients who received locoregional treatment and systemic treatment.
