Investigation of Desmoplastic Squamous Cell Carcinoma

Squamous Cell Carcinoma of the Skin

Aim of the study is to verify wether it is possible to have a more sensitive diagnostic tool using pancytokeratin immunohistochemistry for desmoplastic squamous cell carcinoma compared to regular H&E staining. The investigators therefore plan to include 73 participants with a confirmed diagnosis of desmoplastic squamous cell carcinoma and do regular follow up.

The Oral Microbiome and Upper Aerodigestive Squamous Cell Cancer

Oral Cancer

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.

CTC Detection Rate in SCCHN With a in Vivo Device

Circulating Tumor CellSquamous Cell Carcinoma of the Head and Neck

Detection rate and isolation yield of CTC is low in squamous cell carcinoma of head and neck (SCCHN) with in vitro approaches rely on limited sample volumes. In this study, we applied a new method, the CellCollector, which could capture CTC in vivo from peripheral blood.

Performance of White Light, NBI and Iodine Staining Endoscopy in the Diagnosis of Esophageal Lesions...

Mild Dysplasia of EsophagusModerate Dysplasia of Esophagus3 more

The investigators aim to evaluate the performance of Narrow Band Imaging (NBI) endoscopy in Esophageal Squamous Cell Carcinoma (ESCC) screening, as compared to the currently used White Light Endoscopy (WLE) and Lugol's Iodine Staining Endoscopy (ISE). NBI is a simple, safe and non-invasive technique, which can provide real-time optical staining for suspicious lesions. This trial is designated to enroll 10000 participants from five centers located in different regions (North, West and South) in China, which would provide real-world evidence for the recommendation of endoscopic diagnostic technique used in ESCC screening projects.

Analysis of Patterns of Recurrence in Head and Neck Cancer Using Clinicopathomic Markers

Head and Neck NeoplasmSquamous Cell Carcinoma of Head and Neck

Here, the investigators will develop a clinicopathomic assay from biomarkers obtained from digital pathologies of resected whole-mount oral cavity and oropharyngeal squamous cell carcinoma (OCSCC and OPSCC) specimens with the goal of administering personalized novel image-guided therapies immediately after primary surgical management in OCSCC and OPSCC patients. The primary aim is to determine the association between clinicopathomic biomarkers and LRR. The secondary aim is to develop a clinicopathomic risk score (assay) such that a decision-support tool can be used by physicians for measuring the benefit of additional therapies (i.e. conventional chemotherapy +/- radiation or administering dose-escalated chemoradiation) in the adjuvant setting to reduce LRR rates.

Comparison of Voice Results at 5 Years of Treatment of Glottic Squamous Cell Carcinoma T1 by Surgery...

Glottic Carcinoma

Patients with early-stage squamous cell carcinomas of the vocal cord can be treated in an equivalent way in terms of carcinology by surgery or radiotherapy. The study will be to analyse the vocal outcome at 5 years of these two types of management in order to define whether one is superior to the other on this criterion of voice quality after treatment.

HIV and Other Risk Factors for Esophageal Squamous Cell Carcinoma in Malawi

Esophageal Squamous Cell Carcinoma

The primary purpose of this single-center, case-control, non-interventional study is to determine risk factors which contribute to the development of esophageal squamous cell carcinoma (ESCC) at Kamuzu Central Hospital (KCH) and St. Gabriel Hospital (SGH) in Malawi.
