Icotinib is a new epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that developed and used in China; this work was to evaluate its efficacy and safety in treating non-small cell lung cancer (NSCLC). Clinical studies evaluating the efficacy and safety of icotinib in treating NSCLC were identified from the databases of Medline, Web of Science, Embase and Cochrance Library. Pooled efficacy and safety of icotinib were calculated through a series of predefined search strategies. A total of 15 studies with 2,304 patients were involved in this study...

Skin rash is a side effect of drugs that inhibit epithelial growth factor receptor (EGFR) as a part of targeted therapy of cancer. Its appearance and severity correlates with survival. Minocycline, an oral tetracycline antibiotic, is recommended as treatment (and increasingly, for prevention) of the rash, though infection is seen in only one-third of the patients. Minocycline has additional anticancer properties such as poly(ADP-ribose) polymerase inhibition. It is proposed that such properties contribute to the efficacy of EGFR inhibitors and can also explain the positive correlation between grade of rash and survival as patients with higher grades of rash are more likely to receive minocycline...

PURPOSE: Cetuximab and panitumumab are monoclonal antibody inhibitors that bind the epidermal growth factor receptor (EGFR) currently used in the treatment of metastatic colorectal cancer. The main adverse event related to EGFR inhibitors (EGFR-Is) is cutaneous toxicity, which can cause dosage reduction and interruption of treatment. State-of-the-art management of skin toxicity associated with EGFR-Is therapy involves the topical administration of corticosteroids and oral antibiotics, but is not completely effective in the management of toxicity...

BACKGROUND: Epidermal growth factor receptor (EGFR) mutations occur in about 50% of Asian patients with non-small cell lung cancer (NSCLC). Patients with advanced NSCLC and EGFR mutations derive clinical benefit from treatment with EGFR-tyrosine kinase inhibitors (TKIs). This study assessed the efficacy and safety of adjuvant icotinib without chemotherapy in EGFR-mutated NSCLC patients undergoing resection of stage IB-IIIA. METHODS: Our retrospective study enrolled 20 patients treated with icotinib as adjuvant therapy...

Metastasis of lung cancer to soft tissue is rare and patient outcomes are generally poor. There are no reports describing soft tissue metastasis in lung squamous cell carcinoma (SCC), in which gefitinib treatment was effective not only for the primary tumor but also the metastatic lesion. A 61-year-old Asian woman presented to our facility with pain and a mass in the brachium. An additional tumor was identified in the lung. As we suspected soft tissue metastasis of lung cancer, an incisional biopsy was performed, yielding a diagnosis of SCC...

Epidermal growth factor receptor (EGFR) inhibitors are biological factors used in the treatment of non-small-cell lung cancers (NSCLC) that are positive for EGFR mutations. Afatinib is one such drug that has been approved for use in this capacity. Cutaneous toxicity is the second most commonly reported adverse event with the use of afatinib. A 39-year-old woman with inoperative right lung adenocarcinoma was initially treated with afatinib. She not only developed a severe papulopustular eruption but also had a dramatic reduction of her tumor...

Erlotinib is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor that showed activity against pancreatic ductal adenocarcinoma (PDAC). The drug's most frequently reported side effect as a result of EGFR inhibition is skin rash (SR), a symptom which has been associated with a better therapeutic response to the drug. Gene expression profiling can be used as a tool to predict which patients will develop this important cutaneous manifestation. The aim of the present study was to identify which genes may influence the appearance of SR in PDAC patients...

Squamous cell carcinoma (SCC) of the skin accounts for 20 % of non-melanoma skin cancer and is one of the most frequent types of cancer in Caucasian populations. Diagnosis is based on the clinical features and should be histopathologically confirmed to adequately address the prognosis and treatment. Complete surgical excision with histopathological control of excision margins is the gold standard in the treatment of primary SCC. Sentinel lymph node biopsies (SLNB) can be considered in SCC with a tumor thickness of >6 mm but there is currently no evidence concerning prognostic and therapeutic effects...

Cyasterone was demonstrated potential inhibition effect in mouse skin carcinoma cells in published report. However, the molecular mechanisms of the cyasterone on cells remain unknown. Herein, we investigated the effects of cyasterone-induced apoptosis in A549 and MGC823 cells in vitro. MTT assay showed that cyasterone caused a significantly decreasing of the proliferation of A549 and MGC823 cells in a time-and dose-dependent manner with IC50 values of 38.50±3.73μg/mL on A549 cells and 32.96±1.24μg/mL on MGC823 cells at 48h, respectively...

The acquisition of a resistance EGFR mutation in exon 20 (T790M) occurs in half of the cases of secondary resistance to EGFR tyrosine kinase inhibitors (TKI), given in first-line treatment in advanced EGFR-mutated non-small cell lung cancers (NSCLC). Osimertinib (AZD9291, Tagrisso(®)) is a third-generation, irreversible EGFR TKI, active in case of T790M mutation. A large phase I trial showed the efficacy of osimertinib after failure of first-generation EGFR TKI (erlotinib, gefitinib), with response rate at 51% and up to 61% in case of T790M mutation...

Alectinib has been approved for the treatment of patients with anaplastic lymphoma kinase (ALK) gene rearrangement-positive advanced non-small cell lung cancer. In terms of adverse effects, the occurrence of a severe skin rash induced by alectinib is reportedly rare, compared with the occurrence of skin rash induced by epithelial growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). In the present case report, a 76-year-old woman with ALK-positive lung adenocarcinoma experienced disease progression after undergoing first-line chemotherapy...

Skin toxicity is the most common toxicity caused by Epidermal Growth Factor Receptor (EGFR) inhibitors, and has been associated with clinical efficacy. As EGFR inhibitors enhance the expression of antigen presenting molecules in affected skin keratinocytes, they may concurrently facilitate neo-antigen presentation in lung cancer tumor cells contributing to anti-tumor immunity. Here, we investigated the modulatory effect of the EGFR inhibitor, erlotinib on antigen presenting molecules and PD-L1, prominent immune checkpoint protein, of skin keratinocytes and lung cancer cell lines to delineate the link between EGFR signaling pathway inhibition and potential anti-tumor immunity...

: : Inhibition of the epidermal growth factor receptor (EGFR) is an established treatment that extends patient survival across a variety of tumor types. EGFR inhibitors fall into two main categories: anti-EGFR monoclonal antibodies, such as cetuximab and panitumumab, and first-generation tyrosine kinase inhibitors, such as afatinib, gefitinib, and erlotinib. Skin reactions are the most common EGFR inhibitor-attributable adverse event, resulting in papulopustular (acneiform) eruptions that can be painful and debilitating, and which may potentially have a negative impact on patients' quality of life and social functioning, as well as a negative impact on treatment duration...

The BRAF(V600E) mutation confers constitutive kinase activity and accounts for >90% of BRAF mutations in melanoma. This genetic alteration is a current therapeutic target; however, the antitumorigenic effects of the BRAF(V600E) inhibitor vemurafenib are short-lived and the majority of patients present tumor relapse in a short period after treatment. Characterization of vemurafenib resistance has been essential to the efficacy of next generation therapeutic strategies. Herein, we found that acute BRAF inhibition induced a decrease in active MMP-2, MT1-MMP and MMP-9, but did not modulate the metalloproteinase inhibitors TIMP-2 or RECK in naïve melanoma cells...

The Epidermal Growth Factor Receptor (EGFR) is centrally involved in the regulation of key processes of the epithelia, including cell proliferation, survival, differentiation, and also tumorigenesis. Humanized antibodies and small-molecule inhibitors targeting EGFR were developed to disrupt these functions in cancer cells and are currently used in the treatment of diverse metastatic epithelial cancers. By contrast, these drugs possess significant skin-specific toxic effects, comprising the establishment of a persistent inflammatory milieu...

REVIEW
Martin Holcmann, Maria Sibilia
The epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase that is frequently mutated or overexpressed in a large number of tumors such as carcinomas or glioblastoma. Inhibitors of EGFR activation have been successfully established for the therapy of some cancers and are more and more frequently being used as first or later line therapies. Although the side effects induced by inhibitors of EGFR are less severe than those observed with classic cytotoxic chemotherapy and can usually be handled by out-patient care, they may still be a cause for dose reduction or discontinuation of treatment that can reduce the effectiveness of antitumor therapy...

Non-small cell lung cancers (NSCLC) with activating EGFR mutations become resistant to tyrosine kinase inhibitors (TKI), often through second-site mutations in EGFR (T790M) and/or activation of the cMet pathway. We engineered a bispecific EGFR-cMet antibody (JNJ-61186372) with multiple mechanisms of action to inhibit primary/secondary EGFR mutations and the cMet pathway. JNJ-61186372 blocked ligand-induced phosphorylation of EGFR and cMet and inhibited phospho-ERK and phospho-AKT more potently than the combination of single receptor-binding antibodies...

MLN4924, also known as pevonedistat, is the first-in-class inhibitor of NEDD8-activating enzyme, which blocks the entire neddylation modification of proteins. Previous preclinical studies and current clinical trials have been exclusively focused on its anticancer property. Unexpectedly, we show here, to our knowledge for the first time, that MLN4924, when applied at nanomolar concentrations, significantly stimulates in vitro tumor sphere formation and in vivo tumorigenesis and differentiation of human cancer cells and mouse embryonic stem cells...

Dear Editor, Inhibition of the epidermal growth factor receptor (EGFR) is a new strategy in treatment of a variety of solid tumors, such as colorectal carcinoma, non-small cell lung cancer, squamous cell carcinoma of the head and neck, and pancreatic cancer (1). Cetuximab is a chimeric human-murine monoclonal antibody against EGFR. Cutaneous side effects are the most common adverse reactions occurring during epidermal growth factor receptor inhibitors (EGFRI) therapy. Papulopustular rash (acne like rash) develop with 80-86% patients receiving cetuximab, while xerosis, eczema, fissures, teleangiectasiae, hyperpigmentations, and nail and hair changes occur less frequently (2)...
