Active clinical trials for "Carcinoma, Squamous Cell"

Standard treatment for non-operable cervix cancer is radiation and chemotherapy. This treatment combination can result in significant radiation side-effects involving the bladder, small bowel and rectum. To improve results with radiation/chemotherapy, higher radiation doses have been tried for cervix cancer patients. Results from using higher radiation doses show that cervix tumours may be better controlled, but the radiation side-effects are worsened. Intensity modulated radiotherapy (IMRT) and Tomotherapy are new radiation planning and delivery technologies which may allow for delivery of higher radiation doses with less damage to normal organs. The purpose of this project is to determine whether or not IMRT and/or Tomotherapy technology can produce radiation plans that deliver higher doses of radiation to the tumor and lower doses to normal organs when compared to standard radiation plans. The results from this project will provide the basis for possibly treating future cervix cancer patients with Tomotherapy and providing them with improved cure rates along with decreased rates of radiation side effects. No patients will be treated on this protocol, as the investigators plan to only compare radiation dose calculations from different treatment plans created for test cervix cancer cases. There will be absolutely no patient contact in this protocol.

The goal of this study is to learn how tumors of the upper airway and digestive passages (tongue, throat, mouth, and voicebox) affect the body's immune defenses and energy storage. Previous studies have shown that tumors of the vocal tract produce signals that could help the tumor escape the body's immune defenses and use the body's energy and mineral stores to grow. Researchers are hoping to learn more about what signals give tumor cells an advantage to live and grow, how tumor cells control these signals, and how these signals affect the rest of the body. This study will look closer at researchers belief that tumors in the vocal tract contain genes (genetic information) that abnormally function to allow the tumors to survive and grow against the attack of the body's normal immune system Patients with cancerous tumors (squamous cell carcinoma) and benign (non-cancerous) tumors (papilloma) of the upper aerodigestive tract who are candidates for standard or investigational therapy are eligible to participate in this study. Tumor cells will be collected from patients participating in the study, who will undergo standard surgical treatment or biopsies for their conditions. Once tumor cells are collected they can be analyzed for their genetic make-up. In addition, patients will undergo several tests using skin, blood, and urine to look closely at the function of their immune systems and metabolism.

Evaluation of the prognostic potential of tumor-infiltrating lymphocytes and PD-L1 expression in non-metastatic squamous cell carcinoma of the head and neck

The primary endpoint will be acute toxicity. Secondary endpoints included: late toxicity and quality of life; loco-regional control, disease free survival and overall survival.

Squamous cell carcinomas (SCC) are the second most common skin cancer in humans. The incidence of SCCs in the USA in 2012 was estimated at 700,000 casesSCCs have a metastatic course in 3% to 5% of cases that is of poor prognosis. In men, the SCCs of the scalp represent the most frequent location of the head and neck, the 3rd location of the whole body. The SCCs of the scalp are more undifferentiated than in other locations. In addition, actinic keratoses of scalp, precursors of SCC, are more resistant to treatment than in other areas. These particularities of the SCCs of the scalp suggest the existence of specific factors at the epidermis level of the scalp. UV-induced damage to DNA is the defining event in skin photocarcinogenesis. It has already been shown that DNA damage induced by UV and the kinetics of repair of this damage may vary with age or phototype of patients, but the topographic variation of DNA damage has never been studied, although it is known that gene expression in skin cells may differ from one region of the body to another. the hypothesis is therefore that the particular characteristics of KAs and SCCs at the scal level could be explained by an increased sensitivity to UV-induced damage. It is planned to study UV-induced damage and its repair at the scalp level in humans compared to the forearm.

Narrow-Band Imaging (NBI) is as sensitive as Lugol chromoendoscopy to detect oesophageal squamous cell carcinoma (SCC) and appears more specific than Lugol chromoendoscopy in expert centres but its specificity in current practice is not known. This study aimed to prove the superiority of NBI specificity over Lugol chromoendoscopy to detect oesophageal SCC and high-grade dysplasia (HGD) in current practice (including tertiary care centres, local hospitals and private clinics).

Open, multicenter, single arm, phase II, biomarker driven umbrella trial for head and neck squamous cell carcinoma (FGFR inhibitor, CDK4/6 inhibitor, pan HER inhibitor, PI3K inhibitor, PD1/PD-L1 inhibitor)

The purpose of this study is to assess the safety of nivolumab in routine cancer practice in China. Part one of the study will investigate nivolumab for non-small cell lung cancer previously treated with platinum-based chemotherapy that has locally advanced or has spread. Part two will investigate nivolumab for post-platinum squamous cell carcinoma of head and neck that is recurrent or has spread. Part three will investigate nivolumab for locally advanced or metastatic non-small cell lung cancer. Part four will investigate nivolumab for recurrent or metastatic squamous cell carcinoma of head and neck.

Evaluation of long-term efficacy outcomes of patients previously treated with the Alpha DaRT seeds for management of their malignancy following initial response.

To clarify the effect of Two-field or Three-field Lymphadenectomy on the survival of esophageal squamous cell carcinoma.
