Active clinical trials for "Carcinoma, Squamous Cell"

Investigation of the molecular mechanism and clinical significance of the interplay between Twist1 and other EMT regulators through microRNA-29 family.

Neoadjuvant chemoradiotherapy treatment represents the standard approach for resectable locally advanced esophageal squamous cell carcinoma. The incidence of pulmonary infection and other perioperative complications were higher in patients who received esophagectomy and neoadjuvant chemoradiotherapy than those without neoadjuvant treatment and surgery patients. However, reliable clinical data can quantify the damage degree of immunologic function caused by chemotherapy and radiotherapy is still unknown. This project regards the level of lymphocyte and immunocyte in peripheral blood as a quantitative index to reflect the dynamic change of the immunologic function of patients with locally advanced esophageal squamous cell carcinoma after neoadjuvant chemoradiotherapy treatment. Meanwhile, the investigators will also investigate the relationship between the level of lymphocyte and immunocyte in peripheral blood and the response rate of neoadjuvant therapy.

In this study, we compared a negative pressure wound therapy, versus a conventional dressing in order to evaluate the most efficient wound therapy closure after axillary and inguinal lymph nodes dissections in the management of metastatic skin tumors. A vacuum assisted closure therapy should prevent these comorbidities.

The purpose of the study is to assess the role of lymphoscintigraphy as a simple and widely accessible method with a favorable cost/benefit ratio in improving oral cavity and oropharyngeal squamous cell carcinoma staging and surgical appropriateness and implementing a tailored surgical approach to cervical lymph node dissection.

Since other genital infections enhance HIV susceptibility by inducing inflammation, the investigators study the relationship between the vaginal microbiota composition and the risk of HPV infection, cervical cytological abnormalities in postmenopausal women.

The mortality rate of oral cancer in Taiwan is still high with no decrease. One of the reasons result in these situations is the patent visits hospital for treatment in late stage of oral cancer. Recently, the government makes effort in oral cancer screening to find oral potentially malignant disorders (OPMD) early. However, there is no conscience in treatment strategies of OPMD up to now. In this study, we will set a OPMD data bank, and use the cases to find out the potential biomarker, which is able to predict the oral cancer malignant transformation. Sixty OPMD with oral cancer transformation will be recruited, and 60 OPMD with no oral cancer malignant transformation will also be enrolled as the disease control group. Besides, 20 normal cases and 60 oral cancer cases resulting from previous OPMD will be collected. All those groups will detect the expression of p62/SQSTM1 to investigate the possibility that p62/SQSTM1 as a biomarker to predict the malignant transformation of OPMM, and a guideline to treat or not to treat OPMD.

Study comparing level of free radicals in tumor tissue, blood serum and saliva in patients with Squamous Cell Carcinoma of tongue and mouth floor. Patients with benign fibroma of oral cavity and normal gingiva around extracted lower wisdom tooth are used for control

The study's aim is to define imaging and molecular bio-markers for prediction of radiotherapy response of squamous cell carcinomas, in an early treatment phase.

The Role of microRNA-29b in the Oral Squamous Cell Carcinoma

Head and neck Squamous Cell Carcinoma (HNSCC) is one of the most common head and neck malignant tumors .Investigators found that several patients with early TNM stage and poor differentiated HNSCC had poor prognosis, yet someone with advanced TNM stage and well differentiated HNSCC had good prognosis. Hence, Investigators suggested that prognosis factors and survival rates probably related to the differentiation of HNSCC, and prognosis factor of poorly differentiated HNSCC were rare discussed and controversy. Investigating the prognostic factors of poorly differentiated HNSCC is undoubtedly crucial.
