Prediction of postoperative disease-free survival and brain metastasis for HER2-positive breast cancer patients treated with neoadjuvant chemotherapy plus trastuzumab using a machine learning algorithm.
This study aimed to develop mathematical tools to predict the likelihood of recurrence after neoadjuvant chemotherapy (NAC) plus trastuzumab in patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer.
Combined anthracycline-trastuzumab chemotherapy has been associated with LV dysfunction. We aimed to assess early changes in left ventricular (LV) and right ventricular (RV) mechanics associated with combined anthracycline-trastuzumab treatment for breast cancer. As well as explore whether early changes in 2-dimensional (2D)-speckle tracking echocardiography (STE) could predict later chemotherapy-induced cardiotoxicity.
Effect of Adjuvant Trastuzumab for a Duration of 9 Weeks vs 1 Year With Concomitant Chemotherapy for Early Human Epidermal Growth Factor Receptor 2-Positive Breast Cancer: The SOLD Randomized Clinical Trial.
Trastuzumab plus chemotherapy is the standard adjuvant treatment for patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer. While the standard duration of trastuzumab treatment is 12 months, the benefits and harms of trastuzumab continued beyond the chemotherapy are unclear.
Breast cancer is the leading cause of cancer-related mortality in women worldwide. Trastuzumab (Herceptin) is an effective antibody drug for HER2 positive breast cancer; or acquired trastuzumab resistance retarded the use of trastuzumab for at least 70% of HER2 positive breast cancers. In this study, we reported LMO4 (a member of LIM-only proteins) promoted trastuzumab resistance in human breast cancer cells. Over-expression of LMO4 was observed in acquired trastuzumab resistance breast cancer cells SKBR3 ...
Trastuzumab (H) with chemotherapy benefits patients with HER2+ breast cancer (BC); however, we lack head-to-head pairwise assessment of survival or cardiotoxicity for specific combinations. We sought to identify optimal combinations.
Chemotherapy plus 1-year trastuzumab is the standard adjuvant treatment for HER2-positive breast cancer. The efficacy of less extended trastuzumab exposure is under investigation. The Short-HER study was aimed to assess the non-inferiority of 9 weeks vs 1 year of adjuvant trastuzumab combined with chemotherapy.
There is an urgent requirement to identify biomarkers to tailor treatment in human epidermal growth factor receptor 2 (HER2)-amplified early breast cancer treated with trastuzumab/pertuzumab-based chemotherapy.
De novo or acquired resistance in breast cancer leads to treatment failures and disease progression. In human epidermal growth factor receptor 2 (HER2)-positive (HER2+) breast cancer, Src, a non-receptor tyrosine kinase, is identified as a major mechanism of trastuzumab resistance, with its activation stabilizing aberrant HER2 signaling, thus making it an attractive target for inhibition. Here, we explored the causal relationship between Src and HER2 by examining the potential of Zr-trastuzumab as a surroga...
Trastuzumab is a monoclonal antibody against HER2-positive breast cancer. Despite improving the natural history of the disease, there is a number of patients who are resistant to it, whereas all patients will eventually develop resistance and disease will progress. Inconsistent preclinical data show that the IGF-R pathway may contribute to either de novo or acquired resistance to trastuzumab.
One year is the standard duration of adjuvant trastuzumab for human epidermal receptor-2 (HER2) positive (HER2+) breast cancer (BC). Indeed, a shorter duration of trastuzumab can reduce cardiotoxicity and the costs involved and could provide the same benefit as a one-year treatment. We evaluated the available evidence from randomised controlled trials (RCTs) by comparing 1 year versus a shorter duration of adjuvant trastuzumab for HER2+ BC.
A randomized, open-label, Phase III trial of pertuzumab retreatment in HER2-positive locally advanced/metastatic breast cancer patients previously treated with pertuzumab, trastuzumab and chemotherapy: the Japan Breast Cancer Research Group-M05 PRECIOUS study.
The PRECIOUS study (UMIN000018202) is being conducted as a multicenter, randomized, open-label Phase III study to determine if retreatment with pertuzumab is more effective than conventional treatment in HER2-positive locally advanced (LA)/metastatic breast cancer (MBC) patients previously treated with pertuzumab, trastuzumab and chemotherapy. Patients are randomized 1:1 into chemotherapy plus trastuzumab with or without pertuzumab groups. The latest regimen before enrollment did not include pertuzumab, and...
Resistance to trastuzumab remains a common challenge to HER-2 positive breast cancer. Up until now, the underlying mechanism of trastuzumab resistance is still unclear. tRNA-derived small non-coding RNAs, a new class of small non-coding RNA (sncRNAs), have been observed to play an important role in cancer progression. However, the relationship between tRNA-derived fragments and trastuzumab resistance is still unknown.
The development of trastuzumab has significantly improved the prognosis of HER2-positive breast cancer. However, disease recurs in some patients with HER2-positive breast cancer. A new strategy for treating HER2-positive breast cancer is necessary. Although several studies have reported that HER3 is a prognostic factor for HER2-positive breast cancers, phosphorylated HER3 (pHER3) has not been well studied. There has been no survival analysis including immunohistochemistry with trastuzumab as the primary ant...
Tumors that secrete large volumes of mucus are chemotherapy resistant, however, mechanisms underlying this resistance are unknown. One protein highly expressed in mucin secreting breast cancers is the secreted mucin, Mucin 2 (MUC2). While MUC2 is expressed in some breast cancers it is absent in normal breast tissue, implicating it in breast cancer. However, the effects of MUC2 on breast cancer are largely unknown. This study examined the role of MUC2 in modulating breast cancer proliferation, response to ch...
Neoadjuvant chemotherapy can increase the rate of breast-conserving surgery by downstaging disease in patients with breast cancer. The aim of this study was to determine whether patients who received neoadjuvant chemotherapy have equal survival after breast-conservation therapy compared with mastectomy.
Resistance to HER2-targeted therapy with trastuzumab still remains a major challenge in HER2-amplified tumors. Here we investigated the potential role of MEL-18, a polycomb group gene, as a novel prognostic marker for trastuzumab resistance in HER2-positive (HER2+) breast cancer.
The chemotherapy resistance and toxicity of chemotherapy are major problems in breast cancer treatment. However, candidate biomarkers for predicting clinical outcomes and better prognosis remain lacking.
To evaluate cardiotoxicity in patients with human epidermal growth factor receptor 2+ (HER2+) breast cancer (29 left-sided, 23 right-sided) treated with adjuvant whole-breast hypofractionated radiotherapy (HRT) concurrently administered with the humanized monoclonal antibody to HER2, trastuzumab.
Breast cancer and its surgical treatment and chemotherapy have great impact on the immune system. This study aimed to monitor the various T cells in breast cancer patients and evaluate the immune functions.
Several human epidermal growth factor 2 (HER2)-targeted regimens are used to treat HER2-positive (HER2) breast cancer (BC). The goal of this study was to retrospectively determine the pathologic complete response (pCR) rate for trastuzumab and pertuzumab (HP)-containing regimens compared with trastuzumab (H)-containing regimens for stage II to III HER2 BC.
Patients treated with trastuzumab for HER2-positive metastatic breast cancer (HER2+MBC) are living longer, but there is little information on their outcomes and treatment experience beyond the median survival from clinical trials and real-world observational studies. We aim to describe the real-world treatment patterns and overall survival (OS) for women surviving five or more years from initiation of trastuzumab for HER2+MBC.
Maintaining the relative dose intensity (RDI) of adjuvant chemotherapy at ≥ 85% has been associated with improved treatment outcomes in early-stage breast cancer (ESBC). Increasing evidence has suggested that patients aged ≥ 65 years can maintain the optimal RDI for standard chemotherapy regimens. The present study investigated the RDI of newer adjuvant chemotherapy regimens in this demographic.
MicroRNAs (miRNA) are implicated in numerous physiologic and pathologic processes, such as the development of resistance to chemotherapy. Determining the role of miRNAs in these processes is often accomplished through measuring miRNA abundance by PCR, sequencing, or microarrays. We have developed a system for the large-scale monitoring of dynamic miRNA activity, and have applied this system to identify the contribution miRNA activity to the development of trastuzumab resistance in a cell model of HER2 breas...
Quality-of-life (QOL) has been reported to affect the prognosis of many types of cancer, and several studies used various QOL assessment tools to determine the relationship between QOL and cancer prognosis. In this study, QOL-Questionnaire for Cancer Patients Treated with Anti-Cancer Drugs-the Breast (QOL-ACD-B) was modified to be suitable for preoperative chemotherapy (POC) and was named the QOL-ACD-BP.
To evaluate the adjuvant therapy of trastuzumab cost and quality-adjusted life-years (QALYs) in lifetime horizon and describe the use of an economic evaluation in supporting policy-making decisions in the treatment of early-stage breast cancer in Thailand.
