BACKGROUND The GATA3 gene (GATA-binding protein 3) is one of the most frequently mutated genes in breast cancer. The objective of the current study was to determine the clinicopathologic characteristics of patients with breast cancer harboring GATA3 mutations. METHODS The authors examined the somatic mutation status of GATA3 and performed survival(More)
PURPOSE Neoadjuvant chemotherapy (NCT) is a standard treatment option for locally advanced breast cancer. However, the lack of an efficient method to predict treatment response and patient prognosis hampers the clinical evaluation of patient eligibility for NCT. An elevated lymphocyte-to-monocyte ratio (LMR) has been reported to be associated with a(More)
We investigated the loss of somatic mutations in TP53 and PIK3CA in breast cancer tissue after neoadjuvant chemotherapy (NCT) and the clinical relevance of the observed mutation profiles. Samples were derived from three cohorts: Cohort 1 consisting of 206 patients undergoing NCT with matched pre- and postchemotherapy tumor tissues; Cohort 2 consisting of(More)
Invasive cribriform carcinoma (ICC) is a rare histologic subtype of breast cancer. We aimed to investigate the clinicopathological characteristics and survival outcomes of ICC.Using the Surveillance, Epidemiology, and End Results (SEER) database, we identified 233,337 female patients diagnosed with ICC (n = 618) or infiltrating ductal carcinoma (IDC) (n =(More)
PURPOSE Poor prognosis associated with metastasis in breast cancer patients highlights the critical need to develop an effective evaluation model for metastatic potential (MP). We hypothesized that MP could be also indicated by primary tumor size and involved lymph nodes (LNs). METHODS The expected number of involved LNs is defined as tumor size (cm)(More)
The value of sentinel lymph node biopsy (SLNB) in post-neoadjuvant chemotherapy (NCT) patients is still controversial. We aimed to identify predictors and construct a nomogram for predicting the pathologically complete response (pCR) of axillary lymph nodes (ALNs) after NCT in node positive breast cancer patients. In total, 426 patients with pathologically(More)
The hormone receptor (HR) status and human epidermal growth hormone receptor 2 (HER2) status of patients with breast cancer may change following neoadjuvant chemotherapy (NCT). This prospective observational study aimed to evaluate the prognostic impact of receptor conversion in breast cancer patients treated with NCT.Of the 423 consecutive patients who had(More)
OBJECTIVE To examine the relationship between large tumor size and breast cancer-specific mortality (BCSM), especially in a subset of patients with negative lymph nodes (LNs). PATIENTS AND METHODS We used the Surveillance, Epidemiology and End Results registry to identify 107,705 female patients diagnosed from January 1, 1990, through December 31, 2003,(More)
Among chemotherapeutic agents, paclitaxel has shown great efficacy against breast cancer. Prediction of paclitaxel response may improve patient outcomes. Here we show, using exome sequencing, that in comparison with pre-treatment biopsies, two TEKT4 germline variations are enriched in post-treatment tumours. We find TEKT4 variations in ~ 10% of an(More)
BACKGROUND Solitary fibrous tumor's (SFT) demographic features, clinicopathologic characteristics, treatment outcome and disease-specific prognostic factors were unexplored comprehensively. METHODS SEER program was used to identify patients diagnosed with SFT from 1973 to 2012. Overall collected data were analyzed by using the SPSS 18.0. RESULTS In(More)
