“…In the present analysis the majority of patients (83%) were assessed as pN0 and the remaining 17% of patients were pN1. High lymph node involvement (pN3, pN4) has not been observed, which reflects positively on the overall survival (OS) and recurrence-free survival (RFS) time [12,[19][20][21]. The incidence of nodal metastasis is usually lower than in other BCs, especially IDC [21].…”

Introduction: Medullary breast cancer (MdBC) is an uncommon type of breast cancer representing 1-7% of all cases. It is characterized by the occurrence of many histopathological features associated with a high grade of malignancy. Material and methods: Twelve MdBCs chosen from a group of 1,122 women suffering from invasive breast cancer were analyzed. Histopathological examination and analysis of a basic molecular profile, i.e. estrogen (ER), progesterone (PR) and HER2 receptor expression, and their comparison with invasive ductal breast cancer (IDC), were performed. Results: MdBC accounted for 1.07% of all analyzed invasive breast cancer patients. All patients were female, with an average age of 58.54 years. The MdBC group exhibited a larger median tumor diameter (2.05 vs. 1.89 cm), although ≥ T2 tumors comprised 42% vs. 51% for IDCs. Women without regional lymph node involvement (pN0) (83%) formed the largest group. There was a statistically significant difference in the presence of nodal involvement between the studied groups (p < 0.001). Based on the histological grade of malignancy, the majority of MdBC comprised grade II tumors (G2) (93%). In general, MdBC showed statistically higher histologic grade (G1-G3) than IDC (p = 0.003). The 5-year overall survival rate of MdBC patients was 91%. Most MdBCs (92%) were triple-negative, whereas the remaining 8% were HER2 positive. Conclusions: MdBC presented at a younger age than IDC, had a higher histological grade, larger median size and less frequent regional lymph node involvement. Most MdBCs were triple-negative, whereas IDCs were predominantly luminal. Despite numerous aggressive pathological features of MdBC, its clinical outcome and overall prognosis are favorable.

“…Conversely, Aksoy et al. ( 8 ) found that patients with atypical MBC presented significantly superior rates of recurrence and RFS. This may be associated with a smaller number of selected cases, and these patients have less tumour growth and angiogenesis with fewer lymphocytes and mononuclear infiltration.…”

“…In addition, HR status also affected the survival of MBC patients. Some studies found that MBC patients had a higher percentage of triple-negative status, and MBC patients with PR negativity exhibited good prognosis ( 8 , 9 ). However, the prognostic factors of AMCB were not mentioned.…”

BackgroundA rare subtype of breast cancer, atypical medullary carcinoma of the breast (AMCB), shows a highly adverse prognosis compared to medullary carcinoma of the breast (MBC). The current study aimed to establish a correlated nomogram for the identification of the prognostic factors of AMCB and MBC.MethodsKaplan–Meier and Cox regression analyses were applied to data acquired from the Surveillance, Epidemiology and End Results (SEER) database for 2004 to 2013 to analyse tumour characteristics and overall survival. Propensity score matching (PSM) analysis was performed to determine the overall survival (OS) among those with AMCB and MBC. A predictive nomogram was created, and the concordance index (C-index) was used to predict accuracy and discriminative ability.ResultsA total of 2,001 patients from the SEER database were diagnosed with MBC between 2004 and 2013, including 147 patients diagnosed with AMCB. The number of diagnoses gradually increased in both groups. Cox analysis of multivariate and Kaplan–Meier analysis showed that older age (HR = 3.005, 95% CI 1.906–4.739) and later stage were significantly associated with poor prognosis, while cancer-directed surgery was an independent protective factor (HR = 0.252, 95% CI 0.086–0.740). In the HR-negative stratification analysis, older age (HR = 2.476, 95% CI 1.398–4.385), later stage and histological type (HR=0.381, 95% CI 0.198-0.734) were found to be independent prognostic factors for low standard survival. The log-rank analysis demonstrated significantly worse prognostic factors for patients with AMCB than for those with MBC (P = 0.004). A nomogram (C-index for survival = 0.75; 95% CI 0.69–0.81) was established from four independent prognostic factors after complete identification.ConclusionsMBC is rare, and cancer-directed surgery, older age, and later stage are independently linked with prognosis. In the HR negative population, AMCB patients show a worse survival gain than those with MBC.

“…3 However, the prognosis of hormone receptor-negative patients is not very poor; several reports indicated that the prognosis of some patients with medullary cancer is relatively good, suggesting that it is related to the heterogeneity of the tumors. 4,5 TNBC is a subtype of breast cancer that lacks clinical therapeutic approaches due to the lack of corresponding therapeutic receptors and poor therapeutic efficacy of endocrine therapy and the molecular targeting of the drugs. 6,7 Studies have shown that TNBC is characterized by high proportion of young patients, high histological grade, high rate of axillary lymph node metastasis, low disease-free survival (DFS) and low overall survival (OS) compared with those in non-TNBC.…”

Background: Previous studies have shown that kinesin family proteins (KIFs) play an indispensable roles in several types of cancer. However, the expression and clinical significance of KIFs in triple-negative breast cancer remain unclear. Methods: In this study, the role of KIF15, including gene expression analysis, methylation characteristic, CNV characteristic, and miRNA target regulation, was evaluated using multiple bioinformatic tools based on TCGA database. Quantitative real-time PCR and Western blot were used to determine the expression level of KIF15 in triple-negative breast cancer cell lines. Then, functional experiments were employed to explore the effects of KIF15 on tumor growth and metastasis in triple-negative breast cancer. Results: Our data showed that KIF15 was significantly upregulated in triple-negative breast cancer (TNBC). Functionally, downregulation of KIF15 significantly facilitated apoptosis and G2/M phase arrest, and inhibited the migration and invasion of TNBC cells. The mechanism of action of KIF15 was closely related to DNA replication checkpoint and cell cycle regulation in TNBC based on GSEA. In addition, bioinformatics analysis demonstrated that high expression of KIF15 in TNBC was correlated with copy number aberration and DNA methylation levels. Conclusion: Our findings suggest that KIF15 is a novel oncogene in TNBC and provide us a strong evidence that it might be served as a potential clinical target and biomarker in triplenegative breast cancer.
