Active clinical trials for "Carcinoma, Squamous Cell"

In this study, we aim to assess whether Patient Derived Organoids can be used to predict treatment sensitivity in HNSCC patients.

The study will utilize both retrospective and prospective data collection from patients that already had a bronchoscopy and lung resection or will have a bronchoscopy and lung resection for squamous cell carcinoma. The investigators plan to prospectively collect 5 bronchoscopic biopsies, 10ml blood and one tumor and adjacent normal samples from 200 qualified patients who meet the study criteria.

This early phase I trial studies how well fluciclovine F18 positron emission tomography (PET)/computed tomography (CT) works in identifying the origin of head and neck squamous cell carcinoma in patients with cancer that has spread to the cervical lymph nodes. Fluciclovine F18 during a PET/CT scan may work better in helping doctors learn where the cancer started (called the site of origin) and directing treatment planning compared to standard fludeoxyglucose F-18 (FDG) PET-CT scans.

In squamous cell carcinoma of the tongue, complete surgical resection of the tumor generally represents the primary treatment strategy. Among factors determining the disease prognostic, the surgical margins status is essential for the continued management of the patient, with or without complementary therapies. Generally, surgical margins are defined using visual and tactile elements. Unfortunately, in 15 to 30 percent of cases, they are defined as positive after histopathological examination, on average 5 to 7 days post-surgery. Techniques have recently been developed to analyze the cancerous and non-cancerous nature of tissues, using the spectral properties of tumor cells. SpiderMass™ is an instrument equipped with a probe for tissue micro-sampling and real-time molecular profile analysis. It is thus ultimately a tool for anatomopathological decision support, for diagnosis and prognosis of the disease. Used in the operating room, SpiderMass™ could also become an innovative surgical tool to precisely define cancerous areas in situ and the margins status in intraoperative conditions. Based on the principle of artificial intelligence, the SpiderMass™ machine must initially learn to recognize pathological tissues versus healthy. This project aims to accomplish this first phase of machine learning for squamous cell carcinoma of the tongue.

In the study, N-20190047, the investigators aim to define specific methylation patterns in a group of patients with head and neck squamous cell carcinomas. With this study the investigators aim to validate these findings in a larger cohort.

This is a prospective study on the microbiota associated with oesophageal squamous cell carcinoma (SCC). Patients with newly diagnosed SCC of oesophagus would be recruited for taking samples of oral and oesophageal rinse, tissue biopsies for investigation of the microbiota of oesophageal cancer. Control patients would be identified from patients scheduled for routine endoscopy.

The primary objective of this study is to determine the ex-vivo prognostic accuracy of the Cybrid live tumor diagnostic platform across a basket of solid tumors, using in-vivo RECIST 1.1 as the reference method.

Laryngeal cancer is responsible for 2-5% of all new cancer cases worldwide. Squamous cell carcinoma of the larynx (LSCC) is the most common malignant tumor of the larynx, accounting for 85-90% of all laryngeal malignancies. Despite significant therapeutic developments in recent decades, increases in patients' 5-year survival rates are still minimal , which is likely due to late-stage diagnosis and other complex factors. Therefore, to improve the outcome, timely diagnosis, selection of the most appropriate therapy, and an adequate follow-up approach is needed. The insulin-like growth factor II m-RNA-binding protein 3 (IMP3) is a new biomarker that may be implicated in the carcinogenesis of various malignancies, including head and neck squamous cell carcinoma. IMP3 normally expressed in embryonic tissue but decreases after birth and is no longer detectable in adult tissue With the exception of a few tissues. As a result, IMP3 is expressed only in tumors and not in neighboring normal tissues. Proliferating Cell Nuclear Antigen (PCNA) is a nuclear protein that acts as a cell proliferation marker. In most forms of solid malignancies, such as colorectal cancer and breast cancer, PCNA is closely linked to prognosis and survival. In this study, hoping to improve diagnosis of LSCC and assess prognosis better by using both IMP3 and PCNA biomarkers. As IMP3 may have a role in cell growth and proliferation and PCNA is a marker of cell proliferation; studying the association between both markers in laryngeal carcinoma is recommended.

Esophageal achalasia is a precancerous condition for epidermoid carcinoma; incidence and risk factors for cancer development are not defined. Incidence and risk factors for epidermoid carcinoma development in achalasia patients were investigated.
