INTRODUCTION: Thymic epithelial tumors (TETs) are rare neoplasms with different prognosis lacking consistent molecular alterations possibly leading to targeted therapy. We collected a consecutive series of TETs aimed at investigating the mutational status of druggable genes (EGFR, c-KIT, KRAS, BRAF, PDGFR-alpha and -beta, HER2 and c-MET) and the expression of ALK and PD-L1. PATIENTS AND METHODS: One hundred twelve consecutive cases of TETs and relative clinico-pathologic features were collected...

Although dual HER-2 blockade treatment could offer greater clinical efficacy in breast cancer, the risk of severe toxicities of special interest related to this combined regimen in breast cancer remained unknown. We systematically searched public databases (MEDLINE, EMBASE, Cochrane library) to identify relevant studies that comparing anti-HER2 monotherapy (lapatinib or trastuzumab or pertuzumab) with dual HER-2 blockade treatment (pertuzumab plus trastuzumab or trastuzumab plus lapatinib) in breast cancer...

The incidence of human epidermal growth factor receptor 2 (Her-2) mutations in lung adenocarcinoma is approximately 3%; however, its significance in the management of these lung cancers remains under investigation. We describe an incidental but unique opportunity to evaluate the response to treatment with herceptin in a patient with bilateral synchronous lung primaries in conjunction with breast carcinoma. Interval imaging following surgical resection of the squamous cell carcinoma while on herceptin treatment delineated the radiological regression of the Her-2 positive lung adenocarcinoma...

INTRODUCTION: A large heterogeneous group of unproven remedies exist to treat cancer in both developed and developing countries. Some of these remedies often do more harm than good to the patients. The traditional medicine is the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures. The traditional medicine in Oman is based on herbal treatment and skin treatment (massage, Cupping and skin burn "cautery" treatment-known as Wasam or Kaiy)...

Human epidermal growth factor (HER) 2-directed therapy is the standard treatment for HER2-positive breast cancer. Patients who achieved a pathological complete response (pCR) to the therapy are associated with excellent disease-free survival. However, few molecular markers are available to predict pCR. Here, we aimed to establish a DNA methylation marker to predict the response to trastuzumab and chemotherapy. A total of 67 patients were divided into screening (n = 21) and validation (n = 46) sets. Genome-wide DNA methylation analysis of the screening set identified eight genomic regions specifically methylated in patients with pCR...

BACKGROUND: We previously identified three short single peptides (P4, P6 and P7) representing different B-cell epitopes on the extracellular domain of Her-2/neu for a vaccine that was tested in a phase-I clinical trial. Here we describe the improvement of the multi peptide vaccine by fusing the single peptides to a hybrid peptide P467. METHODS: After coupling to either virosomes or to diphtheria toxoid CRM197 (CRM), the hybrid peptide was tested in different concentrations in combination with either Montanide or Aluminium hydroxide (Alum) in preclinical studies...

Over the last 15 years, we have seen a huge expansion of the development of drugs directed against biomolecular targets within breast cancer cells. The over-expression of certain receptors (ER, PgR, HER-2, VEGF-R), as well as alteration of several intracellular signal transduction pathways (the PI3K-AKT-mTOR pathway, MEK-MAPK pathway, loss of PTEN, etc ...) have a great impact on the likelihood of recurrence and progression of the disease, influencing the natural history of breast cancer. The recent biomolecular classification of breast cancer (Luminal A / B, HER2-driven, Basal Like) allowed finally to identify specific treatments against molecular target to associate or not to traditional chemotherapy, and to use in relation to the prognosis of the disease...

Human ErbB-2 (Her-2) is a critical target for cancer immunotherapy, and its over-expression can promote cancer migration and invasion. Compared with passive antibody therapy, vaccination treatment is more effective in the prevention of cancer recurrence. BALB-neuT mouse is a spontaneous metastasis tumor model used for testing the anti-tumor metastatic effect of rat ErbB-2 (neu) vaccine. However, no spontaneous metastasis tumor model used for evaluating Her-2 vaccine has been developed. In the current study, we attempted to use murine melanoma cell lines to establish a stable spontaneous metastasis tumor model for Her-2 vaccines...

BACKGROUND: Factors associated with tumor recurrence and death in stage T3-gastric adenocarcinoma (GA) after surgical resection remain unclear. In this study, we investigated whether patients with overexpression of epidermal growth factor receptor 2 (HER-2) comprised a high-risk group. METHODS: The immunohistochemistry data of HER-2 protein expression from 633 surgically-resected T3-GA tissues were collected and then retrospectively analyzed by Chi-square test, Kaplan-Meier curve, and log rank test as well as univariate and multivariate analyses...

: 248 Background: The National Comprehensive Cancer Network (NCCN) invites petitions to its scientific panels. Most ( > 95%) are from the pharmaceutical industry lobbying to include their products in the NCCN Guidelines. Rarely, physicians request scientific scrutiny of the guidelines. We report the experience of Oncology Analytics (OA) with petition submissions and the possible impact on guidelines. METHODS: From 2011-2015, OA made 7 petitions to NCCN. The content of each was tracked into subsequent NCCN Guidelines to ascertain whether any changes resulted...

: 288 Background: The 21-gene assay used to estimate breast cancer recurrence and tailor chemotherapy (chemo) receipt has demonstrated predictive validity and clinical utility. Yet it is unclear how involved patients are in the decision to perform the test, or how oncologists use results to recommend systemic chemo. We examined the patient experience with assay testing, physician recommendations, and chemo receipt based on test results. METHODS: The iCanCare study surveyed a weighted random sample of newly diagnosed patients with early-stage breast cancer who were treated in 2013-14, identified through the population-based SEER registries of Los Angeles and Georgia about 3 months after surgical treatment, and merged with SEER data (N=2632, RR=70%)...

: 213 Background: Anthracyclines and anti-Her-2 targeted therapy are commonly used effective breast cancer treatments. They are known to decrease Left Ventricular Ejection Fraction (LVEF), which may increase patients' morbidity and mortality. There is currently no consensus on post treatment cardiac follow-up. Recent observations suggested that ACEI and B blocker drugs could have cardioprotective effects. We conducted a retrospective study to assess patients' cardiac outcome using post-treatment LVEF follow-up and effect of ACEI and B blocker on cardiac outcome for breast cancer patients who received cardiotoxic agents in our institution...

Mixed liposomes, obtained by coaggregation of 1,2-dioleoyl-sn-glycero-3-phosphocholine and of the synthetic monomer containing a gadolinium complex ([C18]2DTPA[Gd]) have been prepared. Liposomes externally decorated with KCCYSL (P6.1 peptide) sequence in its monomeric, dimeric, and tetrameric forms are studied as target-selective delivery systems toward cancer cells overexpressing human epidermal growth factor receptor-2 (HER-2) receptors. Derivatization of liposomal surface with targeting peptides is achieved using the postmodification method: the alkyne-peptide derivative Pra-KCCYSL reacts, through click chemistry procedures, with a synthetic surfactant modified with 1, 2, or 4 azido moieties previously inserted in liposome formulation...

PURPOSE: Resistance to chemotherapeutic agents such as doxorubicin is a major reason for cancer treatment failure. At present the treatment option for metastatic breast cancer is very poor. Therefore, development of an effective therapeutic strategy to circumvent MDR of metastatic breast cancer is highly anticipated. The MDR of metastatic breast cancer cells was accompanied with the overexpression of P-gp transporter. Even though the overexpression of P-gp could be minimized by silencing with siRNA, the question is how they can be selectively targeted to the cancer cells...

PURPOSE: Molecular characterization of disseminated tumor cells (DTCs) in the bone marrow (BM) of breast cancer (BC) patients has been hindered by their rarity. To enrich for these cells using an antigen-independent methodology, we have evaluated a size-based microfiltration device in combination with several downstream biomarker assays. METHODS: BM aspirates were collected from healthy volunteers or BC patients. Healthy BM was mixed with a specified number of BC cells to calculate recovery and fold enrichment by microfiltration...
