Gefitinib is an oral tyrosine kinase inhibitor targeting the epidermal growth factor receptor (EGFR) for non-small-cell lung cancer with EGFR mutations. Although a few studies have analyzed the causes of gefitinib-induced hepatotoxicity, research focusing on the time intervals before and after hepatotoxicity has yet to be reported. Therefore, this study investigated two types of factors: the time to reach gefitinib-induced hepatotoxicity and the time for recovery. From January 2013 to December 2014, a retrospective study was carried out on 473 non-small-cell lung cancer patients who were treated with gefitinib...

BACKGROUND: Transient exacerbation of pain in cancer patients (breakthrough cancer pain, BTCP) despite adequately controlled background pain should be regarded as an independent disease and receive targeted treatment. The opioid of choice is fentanyl, a rapid onset and highly potent WHO category III analgesic. Fentanyl has a strong first pass effect when administered orally and resorbed enterally, however it is well suited for transmucosal administration, e.g. on the oral or nasal mucosa...

Radiotherapy alone, or as an addition to surgery is important for the treatment of head and neck squamous cell carcinoma (HNSCC). In addition to their expression in germ cells, melanoma associated antigens-A (MAGE-A) are only expressed in malignant tissue. Notably, there is a known correlation between MAGE-A9 expression and poor prognosis in HNSCC patients. However, current knowledge regarding the function of MAGE-A9 expression, particularly in the context of irradiation, is limited. MAGE-A9 expression in 37 oral squamous cell carcinoma patents was immunohistochemically determined and analyzed for overall survival by the Kaplan-Meier log-rank test...

For several years, the cause of autosomal recessive mental retardation has been attributed to the deletion or mutation of a gene named tumor suppressor candidate 3 (TUSC3). Previous research has identified that TUSC3 is a potential tumor suppressor gene in oral epidermoid carcinoma, lung cancer and esophageal cancer. However, to the best of our knowledge, no previously published data has existed on the expression of TUSC3 in gliomas. The present study focused on the expression of TUSC3 in brain gliomas. Additionally, the present study sought to identify he association between TUSC3 expression and the typical clinical and pathological disease manifestations of gliomas...

Trans fatty acids (TFAs) are risk factors for cardiovascular disorders, and the cancer-promoting effects of TFAs have been previously reported. The present study examined the effects and signaling of elaidic acid (EA), a TFA, in colorectal cancer (CRC) cells. Oral intake of EA was found to increase metastasis of HT29 human CRC cells. Results indicated that, in the plasma membrane, EA was integrated into cholesterol rafts, which contain epidermal growth factor receptors (EGFR). EA increased nanog and c-myc, and decreased PGC-1A through lipid raft-associated EGFR signaling in HT29 cells...

Paclitaxel (PTX) belongs to a class of taxane anti-tumor drug used for the clinic treatment of breast cancer, ovarian cancer, non-small-cell lung cancer, and so on. PTX has poor water solubility and oral bioavailability. It is generally administered via intravenous (i.v.) infusion. Traditional PTX injectable preparations contain Cremophor-EL and ethanol to improve its solubility, which would result in adverse reactions like severe hypersensitivity, neutropenia, etc. Adverse reactions can be reduced only by complicated pretreatment with glucocorticoid and antihistamines drugs and followed by PTX slow infusion for three hours, which has brought significant inconvenience to the patients...

BACKGROUND: Studies of a modified XELIRI (mXELIRI; capecitabine plus irinotecan) regimen suggest promising efficacy and tolerability profiles in the first-line and second-line settings. Therefore, we aimed to compare the efficacy and safety of the mXELIRI regimen with that of standard FOLFIRI (leucovorin, fluorouracil, and irinotecan), with or without bevacizumab in both regimens, as a second-line therapy for metastatic colorectal cancer. METHODS: We did a multicentre, open-label, randomised, non-inferiority, phase 3 trial...

A busy head and neck or oral and maxillofacial (OMFS) National Health Service (NHS) clinic treats patients with many different conditions. A large proportion will have cancer of the head and neck, and they will be at different stages of their treatment. Their clinical needs may be different from a larger group of patients who have been referred through the "two-week wait" referral pathway, and who are present in the same clinic for their biopsy results. We present our early experience of "fast-track" referrals and their potential effect on the overall volume of work...

PURPOSE OF REVIEW: Dysphagia in adults arises from a range of causes including acquired neurological disorders and some cancers. Previous research has suggested that treatment using neuromuscular electrical stimulation (NMES) when used in conjunction with conventional therapy is effective. This review describes the recent literature and a small prospective case series carried out in the United Kingdom. This study contributed to support National Institute of Clinical Excellence (NICE) guidance for clinicians who wish to include NMES in a rehabilitation programme for dysphagic patients, specifically with reference to safety and the impact on swallowing function of this intervention...

Helicobacter pylori has infected more than half of the world's population, causing gastritis, gastric ulcers, gastric mucosa-associated lymphoid tissue lymphoma and gastric cancer. The oral recombinant Helicobacter pylori vaccine currently used has made great progress in addressing this problem, however, its efficacy and longevity still need to be improved. Th1 and Th17 cells play essential roles in local protection against Helicobacter pylori in the stomach mucosa. Additionally, protective immunodominant antigens are the preferred for a vaccine...

Introduction: The introduction of targeted therapies in renal cell carcinoma has significantly improved its prognosis and treatment outcomes in recent years. Such treatment options are targeted therapies of the vascular endothelial growth factor (VEGF) pathway and the mammalian target of the rapamycin pathway. With the use of tyrosine kinase inhibitors (TKIs) and mammalian target of the rapamycin inhibitors, overall survival has increased up to 2 years. In Turkey, due to applicable reimbursement conditions for patients with metastatic renal cell carcinoma (mRCC), interferon use is mandated as a first-line treatment, thus providing information on the use of everolimus only after initial interferon and second-line VEGF-targeted treatments such as VEGF-TKI...
