BACKGROUND: Necrotizing fasciitis in the head and neck (NF-HN) is a rare and potentially life-threatening condition. The use of hyperbaric oxygen therapy (HBOT) in the acute regimen is disputed and there is a lack of evidence of therapeutic effect. This study aims to describe a retrospective cohort of patients with NF-HN and investigate the use of HBOT and consequences thereof. METHODS: All patients treated for NF-HN at Aarhus University Hospital (AUH) between 2002 and 2014 were included in this retrospective cohort...

Breast cancer (BC) is one of the most common female cancers in the world, with estrogen receptor (ER)-positive BC the most frequent subtype. Tamoxifen (Tam) is an effective drug that competitively binds to the ER and is routinely used for the treatment of ER-positive BC. However, a number of ER-positive BC do not respond to Tam treatment and acquired resistance is often observed, constituting a major challenge for extending patient life expectancy. The mechanisms responsible for these treatment failures remain unclear, indicating the requirement for other targets and better predictors for patient response to Tam...

BACKGROUND: Central nervous system tumours constitute 25% of all childhood cancers; more than half are located in the posterior fossa and surgery is usually part of therapy. One of the most disabling late effects of posterior fossa tumour surgery is the cerebellar mutism syndrome (CMS) which has been reported in up to 39% of the patients but the exact incidence is uncertain since milder cases may be unrecognized. Recovery is usually incomplete. Reported risk factors are tumour type, midline location and brainstem involvement, but the exact aetiology, surgical and other risk factors, the clinical course and strategies for prevention and treatment are yet to be determined...

Cancer is a devastating disease and a large socio-economic burden. Novel therapeutic solutions are on the rise, although a cure remains elusive. Application of microorganisms represents an ancient therapeutic strategy, lately revoked and refined via simultaneous attenuation and amelioration of pathogenic properties. Salmonella Typhimurium has prevailed in preclinical development. Yet, using virulent strains for systemic treatment might cause severe side effects. In the present study, we highlight a modified strain based on Salmonella Typhimurium UK-1 expressing hexa-acylated Lipid A...

BACKGROUND: Antitumor immunotherapy has become a major player in cancer therapy. Ipilimumab is a humanized monoclonal antibody against the cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), an important downregulator of T-cell activation. Ipilimumab has demonstrated tumor regression and improvement in overall survival in patients with metastatic melanoma. Unfortunately, immune activation induced by this drug has been associated with several immune-mediated adverse effects, namely diarrhea and colitis...

BACKGROUND: Although adjuvant therapy (AT) is a necessary component of multimodality therapy for pancreatic ductal adenocarcinoma (PDAC), its application can be hindered by post-pancreaticoduodenectomy (PD) complications. The primary aim of this study was to evaluate the impact of post-PD complications on AT utilization and overall survival (OS). METHODS: Patients undergoing PD without neoadjuvant therapy for stages I-III PDAC at a single institution (2007-2015) were evaluated...

Diabetic retinopathy (DR) is the most common cause of vision loss in patients with diabetes mellitus. Despite the presence of effective therapy, DR is still a significant health burden. A recent research suggests that matrix metalloproteinases (MMPs) could be promising targets, which exert multiple actions on early- and late-stage pathogenesis of DR. Among the MMP family, gelatinases (MMP-2 and MMP-9) act as potent proinflammatory, proangiogenic, and pro-apoptotic factors. Therefore, the pharmacological inhibitory effect of gelatinases on retinal MMP-producing cells may be useful in the treatment or prevention of DR...

Oral cancer is a serious and fatal disease. Cisplatin is the first line of chemotherapeutic agent for oral cancer therapy. However, the development of drug resistance and severe side effects cause tremendous problems clinically. In this study, we investigated the pharmacologic mechanisms of YC-1 on cisplatin-resistant human oral cancer cell line, CAR. Our results indicated that YC-1 induced a concentration-dependent and time-dependent decrease in viability of CAR cells analyzed by MTT assay. Real-time image analysis of CAR cells by IncuCyte™ Kinetic Live Cell Imaging System demonstrated that YC-1 inhibited cell proliferation and reduced cell confluence in a time-dependent manner...

R-spondins play critical roles in development, stem cell survival, and tumorigenicity by modulating Wnt/β-catenin signaling; however, the role of R-spondins in noncanonical Wnt signaling regulation remains largely unknown. We demonstrate here that R-spondin 2 (RSPO2) has an inhibitory effect on colorectal cancer (CRC) cell migration, invasion, and metastasis. Reduced RSPO2 expression was associated with tumor metastasis and poor survival in CRC patients. The metastasis-suppressive activity of RSPO2 was independent of the Wnt/β-catenin signaling pathway but dependent on the Fzd7-mediated noncanonical Wnt signaling pathway...

The pentapeptide, tert-Prenyl(4th)-NH2 (DMePhe-DTrp-Phe-DTrp(N-tert-prenyl)-Leu-NH2), has recently been reported by our group to exhibit properties of substance P (SP) antagonist G against small cell lung cancer (SCLC). In this study, we undertook a systematic structure activity investigation to optimise this lead compound to improve its in vitro anti-tumour activity and biocompatibility. A series of d-tryptophan (D-Trp) derivatives were synthesised, with a range of aliphatic N-alkyl chains (methyl to pentyl) on the indole nitrogen (N(ind))...

Masses are often detected in the abdomen of patients with sizeable ovarian cancer. There are currently no effective treatments available for late-stage ovarian cancer. Immunotherapy is gaining increasing attention worldwide in the clinical setting due to its ability to eliminate tumor cells and its favorable toxicity profile. We herein report the case of a 60-year-old woman who received allogenic natural killer (NK) cell immunotherapy for a sizeable ovarian carcinoma and achieved a noteworthy response. NK cells were isolated from the patient's own peripheral blood mononuclear cells, and the cell numbers were increased to 8-10 billion...

Inoperable or metastatic head and neck squamous cell cancer (HNSCC) is known to be associated with a poor patient prognosis. First line therapies include a Taxol, platinum-based antineoplastic and fluorouracil (FU) treatment regimen (TPF) or a platinum-based antineoplastic, FU and EGFR inhibitor treatment regimen (PFE). The toxicity of these regimens is one of the major limiting factors, particularly for palliative treatment. The present study is a retrospective study of 15 patients with HNSCC, where the treatment goal was palliative...

Nivolumab, an anti-programmed cell death-1 protein monoclonal antibody, is effective for treating patients with late-stage non-small-cell lung cancer. Immune checkpoint inhibitors such as nivolumab induce various kinds of immune-related adverse events, including vitiligo. Vitiligo has been reported in patients with melanoma but not lung cancer. We describe a 75-year-old man with lung adenocarcinoma, stage 4 with pleural and pericardial effusion, that progressed after first-line chemotherapy. Subsequently, he was treated with nivolumab as second-line therapy...

Rare cancers account for about 22 per cent of all cancers diagnosed worldwide, disproportionately affecting some demographic groups, with an occurrence of less than 6 per 100,000 individuals annually. Many rare cancers in adults, adolescents and children are not curable, and patients and care providers have little option to take therapeutic decisions. The epidemiology of rare cancers is a challenging area of study but is inadequately addressed. Despite efforts mainly in some European nations, a few improvements have been observed in the management of rare cancers...

Cancer and its treatment can lead in men to testosterone deficiency, accompanied by somatic and mental symptoms. Germ cell tumours and their treatment may disturb the pituitary-gonadal axis, hence leading to significant clinical abnormalities. In some prostate cancer patients, castration, temporary or permanent, is a desired therapeutic condition. Yet, it is burdened with various side effects of complex intensity and significance. Last but not least, patients in the terminal stage of a malignancy present with low testosterone concentrations as a part of anorexia-cachexia syndrome...

The combination of cisplatin, doxorubicin, and methotrexate was established as the standard backbone of contemporary osteosarcoma therapy in 1986. Since then, however, further improving the survival of patients with osteosarcoma has been challenging-30% to 40% of patients with osteosarcoma still die of this disease. In addition, these patients often experience loss of fertility at a young age, short- and long-term treatment-related cardiotoxicity, and adverse orthopedic effects from surgical resection of the tumor or endoprosthetic reconstructions...
