TumorGraft- Guided Therapy for Improved Outcomes in Head and Neck Squamous Cell Cancer- A Feasibility...
Head and Neck Squamous Cell CarcinomaPrimary objectives: Evaluate the feasibility of rapidly accruing 30 participants with recurrent metastatic head and neck squamous cell carcinoma for the development of patient derived xenographs (PDX) from fresh, real time biopsies in which sensitivity to < 4 Ontario funded chemotherapeutic regimen will be tested. Written feedback to the primary oncologist will be provided. There is also a curative intent cohort of 30 participants undergoing surgical resection with curative intent. These PDX models will undergo exome sequencing with written feedback. Feasibility in both surgical and recurrent cohorts will be a measure of i) engraftment rate, ii) patient status at the time of drug testing completion and iii) rate of accrual.
Outcomes of FoundationOne Directed Therapy in Cancer of Unknown Primary
NeoplasmsUnknown Primary5 moreThe goal of the current study is to determine whether Foundation Medicine's next generation sequencing assay, called FoundationOne, will provide information that allows physicians to make treatment decisions using targeted therapies in clinical trials or FDA approved therapies, including "off-label" agents, that result in superior OS compared to historical outcomes for standard CUP therapy.
Spanish Registry of Mohs Surgery
Skin NeoplasmsCarcinoma9 moreREGESMOHS (Registro Español de cirugía de Mohs) aims at describing effectiveness of Mohs surgery, and patient, tumor and technique factors related to adverse events and tumor recurrence. REGESMOHS is a prospective cohort, including all patients considered for Mohs surgery in participating centers. All consecutive patients are included. The only exclusion criteria are being under 18-years-old or legally incompetent. Pre-planned follow-up is as required by common clinical practice, but at least once a year for the study period.
Role of FCγRIIIA and FCγRIIA Receptor Polymorphisms
Upper Gingival Squamous Cell CarcinomaHypothesis: Cetuximab, an anti-EGFR antibody, is used with radiotherapy in the treatment of locally advanced and inoperable upper aerodigestive tract cancers. Actually, no predictive biomarkers of Cetuximab antitumor activity are known in this setting. It has been shown recently that FCγRIIIA and FCγRIIA receptor polymorphisms played a role in antitumor activity of trastuzumab and cetuximab. The investigators therefore hypothesized that FCγRIIIA and FCγRIIA receptor polymorphisms may play a predictive role in Cetuximab effectiveness in upper aerodigestive tract cancers with recurrence or metastatic disease that make them inaccessible to loco regional treatment.
Assessment of Bmi-1 on Protein and Molecular Levels in Oral Dysplasia and Squamous Cell Carcinoma:...
Oral Squamous Cell CarcinomaThe aim of the current study is to assess the validation of Bmi-1 detection at both protein and molecular levels in oral epithelial dysplasia and oral squamous cell carcinoma as a biomarker for early cancer detection versus biopsy embedded in paraffin blocks.
Role of Myostatin, Activin A and Follistatin Cachexia of ENT Cancers
CachexiaSquamous Cell Carcinoma1 moreThe main objective of our study was to determine the modifications of blood myostatin and activin A concentrations associated with head and neck cancers. Secondary objectives consisted in studying their influence on the occurrence of cachexia, bringing the proof of a tumoral secretion of these factors, and then determining the effect of tumor removal.
Preventing Invasive Cervical Cancer: The Importance of Expectant Management in Young Women With...
High-Grade Squamous Intraepithelial LesionsLesions classified as "High Grade Squamous Intra-epithelial Lesions" (HSIL) are pre-cervical lesions of the cervix, induced by infection with the Human Papilloma Virus (HPV). The detection and proper management of these lesions greatly reduces the incidence of invasive cervical cancer. Pap smear remains the most effective tool for early detection of low and high-grade cervical lesions. In Belgium, screening for cervical cancer is recommended every 3 years for women between 25 and 65 years old. HPV is a virus who possesses certain oncogenic genes who have the ability to inactivate tumor suppressor genes in the host cell. This promotes a tumorigenesis process within the tissues affected by the virus. The majority of human papillomavirus infections are transient and spontaneously cleared by host defense mechanisms, especially in the first two years after exposure. However, 10-20% of infections persist latently and may eventually lead to progression to invasive cervical cancer. Even high-grade lesions kan naturally be cleared, even more so if the patient is young and immuno-competent. Therefore, the management of HSIL lesions in young women has been modified and consists of adopting mainly a conservative attitude, with controls every 6 months for 2 years. This management makes it possible to avoid unnecessary conizations of the cervix which, in young nulliparous patients, are not devoid of heavy obstetric consequences during subsequent pregnancies (premature birth, perinatal mortality). Cervical conization will only be considered for lesions that progress during follow-up or that persist beyond 2 years. However, this type of follow-up requires that patients be compliant. Our study has two main objectives: to determine the compliance of CHU Brugmann Hospital patients who have been proposed a conservative strategy for the management of HSIL lesions. to identify the predictive factors for the persistence and / or progression of high-grade pre-cancerous dysplastic lesions.
Whether it is More Appropriate to Spray Lugol's Solution From Cervical Esophagus to Esophagogastric...
Esophageal Squamous Cell CarcinomaThe aim of this study is to compare the effectiveness and safety of spraying Lugol's solution from cervical esophagus to esophagogastric junction (downward) and from esophagogastric junction to cervical esophagus (upward)during chromoendoscopy.
ALK Tyrosine Kinase Inhibitors in ALK-rearranged Advanced Pure Squamous Cell Carcinoma
Non-small Cell Lung CancerThis study was to explore the efficacy of ALK-TKI in lung squamous cell carcinoma.Approximately 5% of lung adenocarcinomas have oncogenic fusions of EML-4 and ALK a mutation associated with tumorigenesis and migration. Several studies have shown that in patients with ALK-rearranged non-small cells, the use of ALK inhibitors can achieve better efficacy and significantly prolong overall survival. However few of them performed Fish or NGS tests. Our data demonstrates that lung squamous cell carcinoma with ALK rearrangement responds well to ALK-TKI, and correspondingly has a significant improvement in survival time and prognosis, providing a basis for the treatment of ALK-positive patients with lung squamous cell carcinoma. At the same time, we believe that genetic testing is also required for lung squamous cell carcinoma to achieve more accurate medication.
Proximal Molecular Effects of Concurrent Chemoradiotherapy on Head and Neck Squamous Cell Carcinoma...
Head and Neck Squamous Cell CarcinomaThis pilot study seeks to evaluate the feasibility of measuring the proximal effects of concurrent chemoradiotherapy (CRT) on the expression of potential therapeutic target molecules in Head and Neck Squamous Cell Carcinoma (HNSCC). Specifically, this study proposes to evaluate the extent to which CRT induces the differential expression of components along two critical, and potentially interdependent, molecular pathways: the arachidonic acid and epidermal growth factor receptor (EGFR) signaling pathways.
