Aim and background: This study attempted to identify similarities and differences in adverse events (AEs) between human epidermal growth factor receptor 2 (HER2) inhibitors, especially those related to hemorrhagic events and nervous system disorders. Methods: This study summarized the types, frequencies, and system organ classes (SOCs) of AEs of HER2 inhibitors. The US Food and Drug Administration Adverse Event Reporting System (FAERS) data from January 2004 through March 2022 was collected and analyzed. Disproportionality analyses were conducted to detect AEs signals for every HER2 inhibitor...

Breast cancer is the first most common cancer worldwide, and radiation therapy has a major role to play in locoregional adjuvant treatment. In recent years, we have seen the emergence of adjuvant targeted systemic therapies improving the prognosis of patients at high risk of recurrence. Practices concerning combinations of targeted therapies and locoregional radiation therapy for non-metastatic breast cancers often remain heterogeneous due to the low level of evidence and lack of validated recommendations. This literature review covers immunotherapy, CDK 4/6 inhibitors, PARP inhibitors and anti-Her2 therapies...

An improved vaccine is urgently needed to replace the now more than 100-year-old Bacillus Calmette-Guérin (BCG) vaccine against tuberculosis (TB) disease, which represents a significant burden on global public health. Mycolic acid, or cord factor trehalose 6,6' dimycolate (TDM), a lipid component abundant in the cell wall of the pathogen Mycobacterium tuberculosis (MTB), has been shown to have strong immunostimulatory activity but remains underexplored due to its high toxicity and poor solubility. Herein, we employed a novel strategy to encapsulate TDM within a cubosome lipid nanocarrier as a potential subunit nanovaccine candidate against TB...

Purpose : Over the past twenty years, anti-HER2 targeted therapies have proven to be a revolution in the management of human epidermal growth receptor 2 (HER2)-positive breast cancers. Anti-HER2 therapies administered alone or in combination with chemotherapy have been specifically studied. Unfortunately, the safety of anti-HER2 therapies in combination with radiation remains largely unknown. Thus, we propose a literature review of the risks and safety of combining radiotherapy with anti-HER2 therapies. We will focus on the benefit/risk rationale and try to understand the risk of toxicity in early-stage and advanced breast cancer...

BACKGROUND: This study was aimed at estimating the appropriate price of tucatinib plus trastuzumab and capecitabine (TXC), as third-line treatment, in HER2+ breast cancer (BC) patients from the Italian National Health System (NHS) perspective. METHODS: A partitioned survival model with three mutually exclusive health states (i.e., progression-free survival (PFS), progressive disease (PD), and death) was used to estimate the price of tucatinib vs trastuzumab emtansine (TDM-1), considering a willingness to pay (WTP) of 60,000 EUR...

INTRODUCTION: Patients with HER2-positive metastatic breast cancer are at risk for developing brain metastases. Different anti-HER2 treatments can be used in the management of the disease. In this study, we aimed to evaluate the prognosis and the factors affecting the prognosis in brain metastatic patients with HER2-positive breast cancer. METHODS: Clinical and pathological features of HER2-positive metastatic breast cancer patients and magnetic resonance imaging features at the onset of brain metastasis were recorded...

Approximately 20% of breast cancers (BC) overexpress human epidermal growth factor receptor 2 (HER2). This subtype of BC is a clinically and biologically heterogeneous disease that was associated with an increased risk for the development of systemic and brain metastases and poor overall survival before anti-HER2 therapies were developed. The standard of care was dual blockade with trastuzumab and pertuzumab as first-line followed by TDM-1 as second-line. However, with the advent of new HER2-targeted monoclonal antibodies, tyrosine kinase inhibitors and antibody- drug conjugates, the clinical outcomes of patients with HER2-positive BC have changed dramatically in recent years, leading to a paradigm shift in the treatment of the disease...

BACKGROUND: KAMILLA is a single-arm safety study of trastuzumab emtansine (T-DM1) in patients with human epidermal growth factor receptor 2 (HER2)-positive advanced breast cancer (BC; NCT01702571). We report the final analysis of cohort 2 (Asia) within the context of published cohort 1 (Global) findings. METHODS: Patients had HER2-positive, locally advanced, or metastatic BC progressing after chemotherapy and anti-HER2 therapy or ≤6 months after adjuvant therapy...

PURPOSE: Radiotherapy and targeted therapies play a major role in the management of cancers. Unfortunately, the toxicity and efficacy data regarding their association are tenuous and not centralized. Thus, we propose a literature review about the risks and opportunities of combining radiotherapy with targeted therapies. METHODS: We searched databases EMBASE, ClinicalTrial.gov, Medline and Web of Science for the terms « radiotherapy », « radiation therapy », « radiosurgery », « local ablative therapy », « gamma knife » et « stereotactic », combinés avec « cetuximab », « crizotinib », « erlotinib », « gefitinib », « lapatinib » « trastuzumab », "vemurafenib", « panitumumab », « alectinib », « ceritinib », « dabrafenib », « trametinib », « BRAF », « TKI », « MEK », « EGFR », « ALK », « ADC », « trastuzumab », « pertuzumab », « TDM-1 », « trastuzumab emtansine », « TDxd », « trastuzumab deruxtecan », « lorlatinib », « targeted therapy »...

OBJECTIVES: Caregivers of children with medical complexity (CMC) face decisions about life-sustaining interventions, such as tracheostomy. Our objective is to describe the support needs of caregivers of CMC and the resources they use surrounding tracheostomy decision-making (TDM) for their children. METHODS: This qualitative study, conducted between 2013 and 2015, consisted of semi-structured interviews with 56 caregivers of 41 CMC who had tracheostomies, and 5 focus groups of 33 clinicians at a tertiary care children's hospital...

HER2-positive inflammatory breast cancer (IBC) is associated with poor overall survival. Targeted therapies have led to improved outcomes. IBC is underrepresented in clinical trials due to its rareness. This case reports a 52-year-old woman diagnosed with IBC of 119x89mm, axillar node-positive, hormone receptor-negative, HER2 positive. The patient underwent neoadjuvant chemotherapy with dual HER2 blockage. Mastectomy histology showed pathological complete response. After two cycles of adjuvant trastuzumab, the patient developed asymptomatic cardiotoxicity leading to the therapeutic suspension...

BACKGROUND: Evidence on the effectiveness of ErbB inhibitor interventions for women with triple-positive breast cancer (TPBC) is scarce. Exposure to hormone receptors was reported to eclipse targeted intervention effectiveness. Here, we aimed to explore the optimum targeted regimen for TPBC. METHODS: We conducted a thorough search of the literature focusing on neoadjuvant targeted therapy with both hormone receptor-positive and HER2 (ErbB2)-positive patients and performed a network meta-analysis comparing the regimens using a random-effects model...

INTRODUCTION: Trastuzumab emtansine (TDM-1) is an antibody-drug conjugate effective in human epidermal growth factor receptor-2 - expressing advanced breast cancer. Pulmonary complications of TDM-1 are rarely reported. TDM-1-associated interstitial lung disease is referred to as pneumonitis. CASE REPORT: A 47-year-old female patient who underwent modified radical mastectomy and axillary lymph node dissection operations due to a palpable mass in the right breast and axillary region...

BACKGROUND: Anti-HER2 therapy has evolved in the last years and an important role in this transformation was that of monoclonal antibodies and tyrosine kinase inhibitors. Considering their extended use in clinical practice, some toxicity problems have been highlighted around these drugs. OBJECTIVE: To analyze the onset of adverse drug reactions (ADRs) related to the use of HER2-positive breast cancer treatments through a spontaneous reporting system (SRS) database...

PURPOSE: Assessment of HER2 overexpression using immunohistochemistry (IHC) and/or in situ hybridisation (ISH) for the detection of HER2 amplifications is standard to identify patients for established HER2-directed treatments. Patients with lower HER2 expression levels have recently also become candidates for novel therapies targeting HER2. This study aimed to assess tumour and patient characteristics and prognosis in patients with advanced breast cancer (aBC), relative to low HER2 expression levels...

INTRODUCTION: Salivary gland neoplasms (SGNs) respond poorly to the traditional chemotherapy agents limiting the availability of systemic treatment options in the metastatic setting. The recent identification of actionable molecular targets in SGNs has led to the evaluation of targeted therapies in non-approved advanced SGNs. CASE REPORT: We present the case of an elderly male with HER-2 Neu overexpressing metastatic mucoepidermoid carcinoma (MEC) who demonstrated a prompt and sustained disease response to targeted therapies directed against HER-2 Neu with long survival interrupted by hepatoxicity to Trastuzumab emtansine (TDM-1) treatment...

HER2-positive metastatic breast cancer is an aggressive disease with a limited number of treatment options. In the last 15 years, new drugs such as trastuzumab, pertuzumab, lapatinib or trastuzumab emtansine (TDM-1) have sprouted for these patients. There is a huge lack of evidence on the use of some of these drugs in patients with chronic renal failure, who need hemodialysis. We have reviewed the use of TDM-1 in these type of patients in the literature with unsuccessful results. In this article we want to present a case report to illustrate the safety and efficacy of TDM-1 in a patient on hemodialysis...

Metastatic colorectal cancer is the second most common cause of cancer death. Standard chemotherapy in combination with targeted therapies represent the backbone for the treatment of advanced disease. However, options are limited for patients progressing on these regimens. Genetic testing can offer patients the opportunity to benefit from novel therapies, namely immune checkpoint inhibitors in microsatellite instability-positive tumors. HER2 overexpression has recently emerged as a potentially targetable tumor marker in colorectal cancer (CRC)...

INTRODUCTION: No specific standard treatment is currently recommended for HER2-positive advanced breast cancer (BC) patients progressing to dual HER2 blockade and to trastuzumab emtansine (TDM-1). However, several novel anti-HER2 agents are emerging and rapidly revolutionizing this setting. Among these, the FC-engineered monoclonal antibody margetuximab has recently been demonstrated to slightly improve progression-free survival (PFS) compared with trastuzumab, when combined with chemotherapy for pretreated HER2-positive advanced BC...

BACKGROUND: Adolescents and young adults (AYAs) experience treatment nonadherence rates as high as 60%, which can increase the risk of cancer relapse. Involvement of AYAs in treatment decisions might support adherence to medical treatment. OBJECTIVE: The aim of this study was to explore the involvement of AYAs, aged 15 to 20 years, in cancer treatment decision making (TDM). METHODS: Using interpretive focused ethnography, we conducted interviews with 16 AYAs (total of 31 interviews) receiving cancer treatment within 1 year of diagnosis...
