HER2DX in HER2-positive inflammatory breast cancer: correlative insights and comparative analysis with noninflammatory breast cancers.

Background: The HER2DX assay predicts long-term prognosis and pathologic complete response (pCR) in patients with early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer receiving neoadjuvant systemic therapy but has not been evaluated in inflammatory breast cancer (IBC).

Patients And Methods: HER2DX was analyzed in baseline biopsy tissues from 23 patients with stage III HER2-positive IBC on a phase II trial (NCT01796197) treated with neoadjuvant trastuzumab, pertuzumab, and paclitaxel (THP). To assess the assay's predictive accuracy for pCR in IBC, clinical-pathological features and outcomes from this IBC cohort were compared with 156 patients with stage III HER2-positive non-IBC from four different cohorts.

TNBC-DX genomic test in early-stage triple-negative breast cancer treated with neoadjuvant taxane-based therapy.

Background: Identification of biomarkers to optimize treatment strategies for early-stage triple-negative breast cancer (TNBC) is crucial. This study presents the development and validation of TNBC-DX, a novel test aimed at predicting both short- and long-term outcomes in early-stage TNBC. The objective of this study was to evaluate the association between TNBC-DX and efficacy outcomes [pathologic complete response (pCR), distant disease-free survival (DDFS) or event-free survival (EFS), and overall survival (OS)] in the validation cohorts.

Everolimus plus endocrine therapy beyond CDK4/6 inhibitors progression for HR+ /HER2- advanced breast cancer: a real-world evidence cohort.

Purpose: Everolimus in combination with endocrine therapy (ET) was formerly approved as 2nd-line therapy in HR(+)/HER2(-) advanced breast cancer (aBC) patients (pts) progressing during or after a non-steroidal aromatase inhibitor (NSAI). Since this approval, the treatment landscape of aBC has changed dramatically, particularly with the arrival of CDK 4-6 inhibitors. Endocrine monotherapy after progression to CDK4/6 inhibitors has shown a limited progression-free survival (PFS), below 3 months.

Correlation between breast cancer subtypes determined by immunohistochemistry and n-COUNTER PAM50 assay: a real-world study.

Purpose: Molecular subtyping based on gene expression profiling (i.e., PAM50 assay) aids in determining the prognosis and treatment of breast cancer (BC), particularly in hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative tumors, where luminal A and B subtypes have different prognoses and treatments.

Association of HER2DX with pathological complete response and survival outcomes in HER2-positive breast cancer.

Background: The HER2DX genomic test predicts pathological complete response (pCR) and survival outcome in early-stage HER2-positive (HER2+) breast cancer. Here, we evaluated the association of HER2DX scores with (i) pCR according to hormone receptor status and various treatment regimens, and (ii) survival outcome according to pCR status.

Materials And Methods: Seven neoadjuvant cohorts with HER2DX and clinical individual patient data were evaluated (DAPHNe, GOM-HGUGM-2018-05, CALGB-40601, ISPY-2, BiOnHER, NEOHER and PAMELA).

A Dalbavancin for Successful Treatment of Infective Endocarditis Caused by .

Unlabelled: Infective endocarditis is a relatively uncommon infection that requires a high index of suspicion, which can sometimes delay its diagnosis. It requires several weeks of intravenous antibiotics, which traditionally requires long hospital stays. Dalbavancin is a novel antibiotic with high activity against several Gram-positive pathogens.

Quality of life with palbociclib plus fulvestrant placebo plus fulvestrant in postmenopausal women with endocrine-sensitive hormone receptor-positive and HER2-negative advanced breast cancer: patient-reported outcomes from the FLIPPER trial.

Background: In the FLIPPER trial, palbociclib/fulvestrant significantly improved progression-free survival (PFS) compared with placebo/fulvestrant in postmenopausal women with HR+/HER2- advanced breast cancer (ABC).

Objective: We assessed health-related quality of life (QoL) using patient-reported outcomes (PROs).

Design And Methods: In this phase II double-blinded study, PROs were assessed at baseline after every three cycles and at the end of the treatment using the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR23.

HER2+ Breast Cancer Escalation and De-Escalation Trial Design: Potential Role of Intrinsic Subtyping.

Long-term outcomes in breast cancer patients differ based on the molecular subtype, with HER2-E being the most aggressive one. Advances in clinical practice have dramatically shifted HER2+ breast cancer prognosis. Risk adapted strategies to individualize therapies are necessary.

Prospective, multicenter study on the economic and clinical impact of gene-expression assays in early-stage breast cancer from a single region: the PREGECAM registry experience.

Introduction: The aim of this study is to evaluate the cost-effectiveness and impact of gene-expression assays (GEAs) on treatment decisions in a real-world setting of early-stage breast cancer (ESBC) patients.

Methods: This is a regional, prospective study promoted by the Council Health Authorities in Madrid. Enrolment was offered to women with estrogen receptor-positive, human epidermal growth factor receptor 2-negative, node-negative or micrometastatic, stage I or II breast cancer from 21 hospitals in Madrid.

A Pilot, Phase II, Randomized, Open-Label Clinical Trial Comparing the Neurotoxicity of Three Dose Regimens of Nab-Paclitaxel to That of Solvent-Based Paclitaxel as the First-Line Treatment for Patients with Human Epidermal Growth Factor Receptor Type 2-Negative Metastatic Breast Cancer.

Background: This study aimed to characterize the neurotoxicity of three different regimens of nab-paclitaxel compared with a standard regimen of solvent-based (sb) paclitaxel for the first-line treatment of HER2-negative metastatic breast cancer based on the Total Neurotoxicity Score (TNS), a tool specifically developed to assess chemotherapy-induced neurotoxicity.

Materials And Methods: This was a randomized, open-label study testing 4-week cycles of 80 mg/m sb-paclitaxel (PACL80/w) on days 1, 8, and 15; 100 mg/m nab-paclitaxel on days 1, 8, and 15 (NAB100/w); 150 mg/m nab-paclitaxel on days 1, 8, and 15 (NAB150/w); and 150 mg/m nab-paclitaxel on days 1 and 15 (NAB150/2w). In addition to the TNS, neuropathy was assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE).

Successful rectal cancer local recurrence radiofrequency ablation.

Local rectal cancer recurrences represent a great challenge, as surgical re-excisions or re-irradiation procedures are not always feasible. Moreover, scar or local recurrence is hard to elucidate with conventional diagnosis techniques. Emerging diagnostic and therapeutic procedures may be useful in this setting.

Pathological complete response following docetaxel-based neoadjuvant chemotherapy for locally advanced gastric adenocarcinoma.

Locally advanced gastric adenocarcinoma has a poor outcome. Neoadjuvant treatment is being tested in locally advanced non-resectable tumours and in those resectable tumours with a high risk of recurrence. Efforts to identify prognostic factors and more active and less toxic preoperative regimens are being searched for.

New target-based agents involve new clinical trial designs.

Clinical cancer investigation is performed through clinical trials. Development and measurement of clinical efficacy of new target-based agents differs from classic cytotoxic drugs. Whereas the aim of chemotherapy drugs is to destroy tumoral cells, new agents try to inhibit cell profileration without a clear tumor shrinkage.

Brain metastases in metastatic breast cancer patients receiving trastuzumab-based therapies.

Introduction: CNS metastases mean a great challenge. It has been suggested that the brain metastases incidence could be high in metastasic breast cancer patients receiving trastuzumab based-therapies.

Material And Methods: We performed a descriptive analysis of our experience in this setting.
