Correlation Between Pathological and MRI Radiological Tumor Responses to Neoadjuvant Chemotherapy in Non-Luminal Breast Cancer: A Single Institution Experience.

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
backgroundNeoadjuvant chemotherapy (NACT) is the standard treatment for patients with locally advanced breast cancer. In recent years, it has also been used for early-stage triple-negative breast cancer (TNBC) and human epidermal growth factor receptor 2-positive (HER2
objectivesOur hypothesis asserts a correlation between breast radiological and pathological response post-NACT in non-luminal breast cancer patients. We also aimed to determine the predictive value of MRI in predicting response in these patients. Radiologist agreement upon radiological MRI response is also highlighted in the current study.
methodsA retrospective study to evaluate MRI's accuracy for assessing tumor response to NACT in early and locally advanced non-metastatic breast cancer patients in comparison with pathological assessments. We enrolled cases that were treated with neoadjuvant chemotherapy between December 2019 and November 2023.
resultsDynamic MRI's sensitivity to detect tumor response is 86.4%, its specificity is 96.8%, and its accuracy is 92.4%, with a significant p-value. So, the high correlation between measurements of residual disease detected by MRI and those detected by pathological assessment supports the use of MRI for imaging assessment during NACT. The two radiologists involved in our study were in good agreement in their assessment of radiological response (Kappa: 0.801, sensitivity: 85.7%, specificity: 93.8%, and accuracy: 90.6%).
conclusionsThe accuracy of imaging assessment by breast MRI during NACT is validated by the greater correlation between measurements of residual disease on MRI and pathology, establishing its role as the most precise imaging modality. We strongly advocate for the dependable role of MRI in monitoring breast lesions during neoadjuvant therapy, especially in non-luminal breast cancer cases, regardless of whether they present as mass or non-mass enhancement patterns.
