Predictive and prognostic effect of HO-1 expression in breast cancer patients undergoing neoadjuvant chemotherapy.
Article in Breast cancer research and treatment, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
purposeHeme oxygenase-1 (HO-1) has complex biological function, and is a candidate oncogene with a wide variety of deleterious functions in breast cancer. Here, we evaluated the relationship between expression of HO-1 protein with clinical response to neoadjuvant chemotherapy (NAC) in breast cancer patients.
methodsWe used immunohistochemistry (IHC) to determine expression of HO-1 protein from core needle biopsy before NAC, then applied univariate and multivariate analyses to understand the relationship between HO-1 with pathological complete response (pCR) outcomes. Next, Kaplan-Meier and Log-rank tests were used to compare disease-free survival (DFS) and overall survival (OS), between groups, and Cox proportional hazards regression analysis applied for prognostic evaluation.
resultsA total of 575 patients with locally advanced invasive breast cancer were included in the study, of which 111 (19.3%) achieved pCR after NAC. Results from multivariate analysis showed that high HO-1 expression was an independent predictor of low pCR rate (OR 0.254, 95% CI 0.026-0.643, p = 0.002). Moreover, results from survival analysis showed that high HO-1 expression was significantly associated with shorter DFS (HR 4.843, 95% CI 1.205-32.572, p = 0.026), but not with OS (HR 3.219, 95% CI 0.928-32.124, p = 0.071). Furthermore, HO-1 expression was significantly associated with lower pCR rate (OR 0.102, 95% CI 0.013-0.352), p = 0.001), poor DFS (HR 8.562, 95% CI 1.592-34.950, p = 0.009), and OS (HR 7.835, 95% CI 1.220-56.213, p = 0.023) of patients with triple-negative breast cancer (TNBC) patients.
conclusionOur results indicated that HO-1 expression is not only a biomarker for predicting pCR, but also a prognostic factor in breast cancer patients in a neoadjuvant setting, especially in TNBC subgroups.
