Active clinical trials for "Neoplasms, Squamous Cell"

The standard treatment for head and neck cancer relapses in previously irradiated patients is controversial. Reirradiation has had some success, but many patients still die from their disease. Cetuximab is helpful in relapsed head and neck cancer, and it improves the effectiveness of radiation in some head and neck cancer patients. But, it has not been studied with reirradiation. The purpose of this study is to see the effects, both good and bad, of reirradiation with cetuximab.

This study will provide data on the performance of the BD SurePath Plus™ Pap test for identifying high grade cervical disease. This study will be conducted with approximately 12,500 women undergoing routine cervical cancer screening, of whom women with abnormal cytology and/or positive HPV test will be selected to undergo colposcopy and biopsy/ECC. Subjects with abnormal cytology results with biopsy results of less than or equal to CIN1 or CIN2 untreated will be asked to return in 6-8 months for follow-up testing. Subjects may be asked to proceed to a longer-term follow-up study and undergo cytological evaluation annually for 3 years (separate study).

The purpose of the study is to evaluate the usefulness and accuracy of the "LIFE-Lung Bronchoscopy" to identify early changes in lung tissues that show precancerous, cancer in situ (just beginning and not spread) and microscopic invasive cancer lesions versus the ability of the standard "White Light Bronchoscopy" to identify the same. This will be done as a part of routine monitoring bronchoscopy. Patients who have had a surgical resection of non-small cell lung cancer (NSCLC) and with no current evidence of disease (NED) will be eligible. Also eligible are patients who have had head or neck squamous cell carcinoma with radical head and/or neck dissection and who are currently NED. Patients with severe chronic, obstructive, pulmonary disease shown by pulmonary function testing abnormalities will also be eligible. In addition to the specialized bronchoscopy, doctors will be investigating the use of imaging spectroscopy. This is using an optical (visualizing) procedure to measure the light reflected back from tissue. Different lesions and normal tissues reflect light differently and in specific color wavelengths. By using measurements over time (different examinations/bronchoscopies) very small changes can be seen. This may allow eventually for very early diagnosing of precancerous or cancer in situ lesions, allowing for earlier treatment.

The purpose of this study is to assess the effect of metformin in tumor metabolism in patients with head and neck cancer by evaluating metformin's ability to decrease TOMM20 expression in squamous carcinoma cells and decrease MCT4 expression in fibroblasts.

Treatment, In combination with BSC, Open-label, Single arm, Efficacy Study.

The purpose of this study is to determine the safety, tolerability, and the highest dose of GC4419 that can be given to patients with squamous cell cancer of the head and neck who are receiving standard radiation therapy and chemotherapy. This study will also evaluate GC4419 for the following: Effect on the incidence and severity of radiation induced oral mucositis; Effect on the response rate of squamous cell cancer of the head and neck who are receiving radiation therapy and chemotherapy; Total concentrations of GC4419 that can be achieved in the blood; Changes in proteins and genetics associated with oral mucositis; Impact on delayed toxicities of radiation (dry mouth and reduced ability to fully open the mouth); Observe changes in genetic and molecular markers of oral mucositis; Observe the usage of extra health resources (e.g., unplanned ER visits, feeding tube use, etc.) of study patients; Assess the overall quality of life in study patients with oral mucositis.

This study is a multicenter phase Ⅲ trial. The objective is to compare the efficacy and toxicity of cisplatin plus raltitrexed or 5-fluorouracil in concurrence with IMRT for patients with locoregionally advanced head and neck squamous cell cancer.

Irinotecan, as one new agent used in advanced esophageal carcinoma, has been shown to be effective and safe in western studies. Different with westerns, squamous carcinoma is the main pathological type in china patients. The investigators then initiated a prospective phase II clinical trial with irinotecan/cisplatin as the 1st line treatment in advanced esophageal carcinoma to observe the efficacy and safety of the combination.

Nimotuzumab, as one new agent used in advanced esophageal carcinoma, has been shown to be effective and safe in some studies with head-neck cancers. Advanced esophageal carcinoma have poor prognosis and majority of patients resistant to chemotherapy in China. In the investigators phase II clinical trial proceeded before,the combination of paclitaxel with cisplatin showed good tolerance and efficacy to esophageal carcinoma. The investigators then initiated a prospective phase II clinical trial with Nimotuzumabplus paclitaxel/cisplatin as the 1st line treatment in advanced esophageal carcinoma to observe the efficacy and safety of the combination.

Clinical studies related to immunotherapy of HNSCC have shown that PD1 monoclonal antibody has better clinical benefits than conventional chemotherapy. This phase II clinical study is a single arm, open, single-center study. The aim of this study is to observe and evaluate the efficacy and safety of Sintilimab combined with paclitaxel-albumin-binding for injection in patients with advanced recurrent and metastatic HNSCC who fail to receive first-line or more treatment. Participation in this study for treatment may benefit patients with advanced recurrence or metastasis of HNSCC.
