Filter by:The human oral cavity is a diverse habitat that contains approximately 700 prokaryotic species. The oral microbiome is comprised of 44% named species, 12% isolates representing unnamed species, and 44% phylotypes known only from 16S rRNA based cloning studies (http://www.homd.org/). Species from 11 phyla have been identified: Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria, Spirochaetes, Fusobacteria, TM7, Synergistetes, Chlamydiae, Chloroflexi and SR1 (http://www.homd.org/). Because these observations have been mainly based on data generated from traditional Sanger sequencing, the diversity of oral microbiome is highly likely underestimated. Application of high throughput sequencing to the oral microbiome similar to the scale of the microbiome studies of other body sites (GI tract, skin, and vagina) under the Human Microbiome Project is necessary to obtain data essential for understanding the diversity and community structure of the oral microbiome in health and disease.
The purpose of this research is to assess the safety and effectiveness of circumferential radiofrequency ablation (RFA) to the anal canal using the BarrxTM Ablation System to destroy anal high-grade squamous intraepithelial lesions (HSIL). The BarrxTM Ablation System used in this study comprises an RFA generator (Barrx™ FLEX) and the BarrxTM Anorectal Wand. The generator and wand are cleared by the Food and Drug Administration (FDA) for human use and the wand is specifically cleared for treatment of anal intraepithelial neoplasia (AIN). AIN is a precancerous condition. HSIL is an advanced form of AIN. The presence of HSIL has traditionally warranted treatment. RFA has been shown in many studies to effectively and safely destroy precancerous cells in a condition called Barrett's esophagus, which is a precancerous condition of the esophagus (the swallowing tube). Recent studies have shown that RFA may offer the same benefits for those with HSIL in the anal canal. In particular, ablation of the entire circumference of the canal seems to reduce recurrence of HSIL in other locations of the anal canal. This study will last between 12 to 15 months. Subjects will be required to undergo 5 to 8 study visits as outlined below that are carried out by the study doctors or the physician assistant. Most visits will last approximately one hour. Some may be shorter and some may be longer. Up to seventy (70) volunteers will participate in this study at several locations.
Phase II study, randomized, open-label, multicentric, willing to establish the benefit of pursuing chemotherapy beyond 6 weeks for non progressive patients. The study will proceed in two successive phases : - non randomized phase in which all patients will undergo chemotherapy - second phase in which only non progressive patients are going to be randomized ("discontinuation design"). Patients that will show progression in their disease during the first 6 weeks will be released of the study
Oral squamous cell carcinoma (OSCC) are considered as a one of the most malignant cancers. It has prognosis due to its distant metastasis and obvious destruction which lead to low survival rate. The conventional treatment modalities such as surgery, radiotherapy and chemotherapy are only the suitable strategies until now. Investigators cannot ignore the serious side effects of chemotherapy such as gastrointestinal upset, bone marrow suppression which cannot be overcome. For all these complications, there is a great need and demand to discover a new agents and strategies for treating OSCC. Licorice extract, especially Licochalcone A, is one of many natural extracts that have used as a traditional in treatment of inflammation, microbial infections. Regarding antitumor effect, Licochalcone A reveals interesting results in programmed cell death and apoptosis in cancer cells such as prostate, bladder, colon and gastric cancer.
This study evaluates intratumoral administration of CV8102 in patients with advanced melanoma, squamous cell carcinoma of the skin, squamous cell carcinoma of the head and neck, or adenoid cystic carcinoma. Patients will receive CV8102 as single agent or in combination with SoC anti-PD-1 therapy.
In vitro study to examine whether luteolin and nano-luteolin exert an inhibitory effect on tongue squamous cell carcinoma cell line by inducing apoptosis, and to assess if nano-luteolin has more efficient apoptotic activity than luteolin on tongue squamous cell carcinoma cell line.
The purpose of this study is to evaluate the safety and efficacy of pembrolizumab (MK-3475) in adult participants with recurrent or metastatic(R/M) cutaneous Squamous Cell Carcinoma (cSCC) or locally advanced (LA) unresectable cSCC that is not amenable to surgery and/or radiation and/or systemic therapies.
Immunotherapy targeting the PD-1/PD-L1 pathway had previously been shown to be efficacious in the treatment of patients with metastatic head and neck squamous cell carcinomas. Stereotactic Body Radiotherapy (SBRT) to metastatic lesions causes localized cancer cell killing and the release of cancer cell debris, which could stimulate the immune system in the presence of immunotherapy. The purpose of this study is to assess the tolerability and efficacy of combining Durvalumab (MEDI4736), Tremelimumab and SBRT in controlling cancer progression. SBRT will be administered to patients while they are receiving Durvalumab and Tremelimumab.
The purpose of this study is to evaluate the use of Transoral Robotic Surgery (TORS) to identify small oropharyngeal carcinomas. Findings from this study will be used to better determine which patients may be suitable for more targeted radiotherapy that would lead to a reduction in the total amount of radiotherapy needed as part of their treatment. Reducing the amount of radiotherapy received has been found to reduce the risk of late complications and toxicity to the patient.The pathologic findings will then be used to determine patients who may be candidates for de-intensification of radiotherapy.
In this multi-institution phase I/II trial, the investigators have chosen paclitaxel and carboplatin using a schedule and doses identical to those used in the CROSS trial. Following a run-in with nivolumab alone at 240 mg IVPB every 2 weeks for 2 doses, nivolumab at 240 mg every 2 weeks will be added to paclitaxel and carboplatin, which will be dosed according to the standard of care established by the CROSS trial: paclitaxel 50 mg/m2 weekly for 6 weeks and carboplatin AUC 2 weekly for 6 weeks. Concurrent radiation will be administered with chemotherapy at 1.8 Gy/fraction × 28 fractions to a total dose of 50.4 Gy, the standard radiation dose administered in the United States for trimodality therapy that includes concurrent therapy with carboplatin and paclitaxel. A decrease in dose to 41.4 Gy per the protocol established by van Hagen, et al. will be permitted before discontinuing therapy due to unacceptable toxicity. While the CROSS study administered only 5 weekly doses of chemotherapy during the 5 weeks of radiation, the higher dose of 50.4 Gy (1.8 Gy/fraction ×28 fractions over 5½ weeks) utilized in this study permits for a sixth dose during the additional week of radiation.
