Background/aim: Initial treatment of endometrial cancer with surgery and platinum and taxane-based chemotherapy is often successful, but it remains unclear as to whether certain types of the disease relapse. The aim of this study was to identify the clinical features of recurrence in patients without residual tumour in endometrial cancer.

Patients And Methods: Clinical features, histological type, and time to recurrence were analyzed in 640 endometrial cancer patients without residual tumours.

Advanced lung cancer is one of the most lethal malignancies. Many anticancer agents have been developed for lung cancer with epidermal growth factor receptor (EGFR) mutations, but its prognosis remains extremely poor. The development of molecularly-targeted therapies is required for patients with lung cancer with secondary mutation of the EGFR gene.

Ovarian cancer is the most lethal gynecologic malignancy. Recently, several molecularly targeted anticancer agents have been developed for ovarian cancer; however, its prognosis remains extremely poor. The development of molecularly targeted therapy, as well as companion diagnostics, is required to improve outcomes for patients with ovarian cancer.

Background: BK-UM (CRM197) is a mutant form of diphtheria toxin and a specific inhibitor of heparin-binding epidermal growth factor-like growth factor (HB-EGF). We assessed the safety, pharmacokinetics, recommended dose, and efficacy of BK-UM in patients with recurrent ovarian cancer (OC) or peritoneal cancer (PC), and measured HB-EGF levels in serum and abdominal fluid after BK-UM administration.

Methods: Eleven patients with advanced or recurrent OC or PC were enrolled and treated with BK-UM via the intraperitoneal route.

Background/aim: Heparin-binding epidermal growth factor-like growth factor (HB-EGF), which belongs to the epidermal growth factor family, is a rational therapeutic target for triple-negative breast cancer (TNBC). This study aimed to assess the anti-tumor efficacy of intravenous (i.v.

Aim: This study aimed to evaluate the efficacy of aprepitant, a neurokinin (NK)1 receptor antagonist, on chemotherapy-induced nausea and vomiting (CINV).

Patients And Methods: A randomized, open-labeled, parallel-design study was undertaken in gynecologic-cancer (GC) patients at the Fukuoka University Hospital. Twenty-three patients were divided into without (group A) or with aprepitant (Group B) in the first cycle of paclitaxel and carboplatin (TC) therapy.

Aim: The study was designed to evaluate the safety of combined chemotherapy with pegylated liposomal doxorubicin (PLD) and irinotecan (CPT-11) in patients with recurrent ovarian cancer.

Patients And Methods: Six patients with platinum-resistant and taxane-pretreated ovarian cancer were enrolled in the study based on the traditional 3-plus-3 design. PLD was administered intravenously on day 1 and CPT-11 on days 1 and 8 of each 28-day course.

Background/aim: Neuroblastoma (NB) is the most common and lethal extracranial solid tumor in children. The present study aimed to verify that the heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a rational target in NB therapy.

Material And Methods: We examined expression of EGFR ligands in four NB cell lines using 2-dimensional culture (DC) and 3DC conditions.

Eph receptor tyrosine kinases are considered candidate therapeutic targets in cancer, but they can exert opposing effects on cell growth. In the presence of its ligands, Eph receptor EphA2 suppresses signaling by other growth factor receptors, including ErbB, whereas ligand-independent activation of EphA2 augments ErbB signaling. To deploy EphA2-targeting drugs effectively in tumors, the anti-oncogenic ligand-dependent activation state of EphA2 must be discriminated from its oncogenic ligand-independent state.

Colorectal cancer (CRC) is one of the most frequently occurring cancers with high morbidity and mortality worldwide. Amphiregulin (AREG), a member of the epidermal growth factor family and a rational target for CRC therapy, is essential for the three-dimensional structure of tumor formation. To clone the genes associated with increased AREG expression, we performed a cDNA microarray analysis in two CRC cell lines undergoing two-dimensional (2DC) and three-dimensional culture (3DC).

Background/aim: Heparin-binding epidermal growth factor-like growth factor (HB-EGF), a member of the epidermal growth factor family, is a target for ovarian cancer therapy. The present study investigated the administration schedule of BK-UM, an anticancer agent targeting HB-EGF.

Materials And Methods: The ovarian cancer cell line, RMG-I, was injected subcutaneously into five-week-old female nude mice.

Ovarian clear cell carcinoma (OCCC) is a worst histological subtype than other ovarian malignant tumor. Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a promising target for ovarian cancer therapy. The aims of this study were to validate the efficacy of HB-EGF-targeted therapy for OCCC and to identify the transcription factor that contributed to the induction of HB-EGF by SN38 treatment in OCCC cells.

The majority of human tumors display a high rate of glycolysis under aerobic conditions. This phenomenon was recognized approximately seven decades ago and is known as the Warburg effect. Several key enzymes required to maintain this high level of glucose metabolism are found in tumor cells.

Photodynamic therapy (PDT) is a well-established clinical treatment modality for various diseases, including cancer. It involves the topical or systemic administration of a photosensitizer, followed by selective irradiation of the target lesion with a specific wavelength of non-ionizing light, which triggers oxidative photodamage and subsequent death of the targeted cells. Due to this two-step therapeutic process, PDT is a safe and minimally-invasive therapy.

Heparin-binding EGF-like growth factor (HB-EGF) is one of several proangiogenic factors and represents a possible therapeutic target for patients with triple-negative breast cancer (TNBC). However, the role of HB-EGF in promoting tumor aggressiveness in TNBC remains unclear. To investigate specific genes and pathways involved in TNBC tumorigenesis, we profiled gene expression changes in two TNBC cell lines under two-dimensional culture (2DC) and three-dimensional culture (3DC) and in a tumor xenograft model.

Heparin binding epidermal growth factor-like growth factor (HB-EGF) is involved in development and homeostasis as well as in pathological processing of chronic diseases, especially cancer. Enhancement of HB-EGF expression is directly or indirectly regulated by transcriptional factors, including activator protein-1 (AP-1), specificity protein (SP)1, SP3, nuclear factor kappa B (NF-κB), hypoxia inducible factor 1, alpha subunit (HIF-1α, myogenic differentiation 1 (MyoD), Wilms tumor 1 (WT-1) and snail homolog 1 (Snail), and also by microRNAs. These transcription or post-transcription factors may communicate to form an autocrine HB-EGF amplification loop.

Background: Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a rational target for ovarian cancer therapy. The aim of this study was to examine HB-EGF levels in the peritoneal fluid and serum of ovarian cancer (OVCA) patients.

Patients And Methods: Samples were collected from six healthy women, 21 OVCA patients, and 21 ovarian cyst patients.
