This study is designed to evaluate the efficacy of icotinib at routine dose in previously treated non/light-smoking patients with advanced squamous cell lung cancer.
Treatment of locally advanced and metastatic squamous cell carcinoma of the lung involves the use of chemotherapy as the therapeutic mainstay. Platinum-etoposide regimens (such as cisplatin-etoposide) are the most commonly used chemotherapeutic regimen, which is delivered intravenously in the standard three-weekly intervals. Recent interest in oral metronomic chemotherapy has arisen, especially due to its beneficial effects in delaying disease progression among heavily pre-treated patients with various malignancies. This study attempts to combine the use of metronomic chemotherapy concurrently during standard intravenous chemotherapy.
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.
By using a novel technique of extraesophageal saline injection (ESI),the esophagus is to be separate from the adjacent organs.The space between esophagus and adjacent organs can be detected by endoscopic ultrasonography enhanced with ESI.Therefore, ESI plus with EUS is to be differentiate between T3 and T4 stage esophageal squamous cell carcinoma (ESCC). The objective of this Phase Ⅰstudy is to confirm the safety and efficacy of ESI.
Anal cancer is treated with chemoradiotherapy- combined chemotherapy and radiotherapy. This is very successful (75% long term survival). During the course of the radiotherapy, other organs in the pelvis may be damaged. This can lead to long-term problems with possible changes to the skin, bowels with diarrhoea and incontinence problems, bladder shrinkage and incontinence of urine, sexual problems including impotence and ejaculatory problems, or pain during sexual intercourse with vaginal dryness and shrinkage. Patients should be offered help with these side effects. At present, there is very little information on the effect treatment has on a patient's quality of life, making it difficult to judge if new treatment methods are better. This project will measure quality of life from the patient's perspective after treatment for anal cancer. It will also gather preliminary data on quality of life after the introduction of a new technique for more precise 3D-targeting of radiotherapy beams at the cancer, called IMRT.
To compare the Disease free survival (DFS) rate of a preoperative cetuximab treatment followed by operation and postoperative radiation-cisplatin-cetuximab treatment paradigm for advanced oral cavity cancer, , with the DFS rate of historical controls (from the RTOG 9501 and EORTC 22931 studies in which treatment was with surgery followed by radiotherapy and cisplatin) with a similar stage of the disease.
Evidence from laboratory studies suggests that aspirin and tea polyphenols may have an antineoplastic effect in esophageal squamous cell carcinoma (ESCC). To assess the safety and efficacy of aspirin and tea polyphenols for preventing ESCC, the investigators designed this double-blind, randomized controlled clinical trial. Research project is planned to recruit 10,000 participants with the ages of 40-60 years in Fengfeng city, Hebei province, China, which has been known as a high incidence region of ESCC. All the participants receive endoscopic examination. Lugol's chromoendoscopy is used to identify esophageal unstained lesions (USLs). The location and size of each USL will be recorded followed by collecting biopsy samples from each USL. Participants with USL are randomly assigned to receive 100 mg/d of aspirin (n=200), 100 mg/d of tea polyphenols (n=200), or placebo (n=200) for six months. Follow-up consists of 2 endoscopic surveillance cycles (the first interval will be at six months and the second at 3 or 5 years later). The primary outcome measure was occurrence of high grade dysplasia and invasive ESCC. Secondary outcome was the mortality of the participants and adverse events.
Translocator protein (TSPO) is a intracellular protein that is found primarily in the outer membrane of the mitochondria that is encoded by the TSPO gene. It has been found that TSPO expression in the skin correlates with cell proliferation and differentiation. Many studies have shown that TSPO overexpression in solid malignancies such as in ovarian cancer, colon cancer, and others, was also found to correlate with more aggressive cancer behavior. Working Hypothesis and Aims: Previous studies described an aberrant expression of TSPO levels in solid malignancies as compared to normal tissues. It is assumed that this aberration can be found in cuntaneous malignancies as well. The occurrence of this aberration may lead to the understanding of the mechanism of TSPO involment in the cutaneous malignancy, and in malignancies in general. Methods: The study will be carried out on surgically resected skin lesions suspected to SCC or BCC, which will be removed as part of the surgical routine treatment. The excision will be made in elliptic shape including the lesion and a part of normal skin surrounding it. A sample will be taken from the central part of the lesion and from the external extremity of the normal tissue. Western Blot will be conducted to detect the expression of TSPO. Binding activity with the TSPO specific ligandwill also be determined. Expected Results: We expect to observe either (a) a higher level of TSPO expression and a lower binding activity in malignant tissue compared with healthy control tissue or (b) a higher level of TSPO expression and a lower binding activity in malignant tissue compared with healthy control tissue. Importance: Until today, only a very small number of studies have examined TSPO in cutaneous malignancies, and these only examined TSPO expression. Our study will also measure the binding activity of TSPO in cutaneous malignant tissues compared to normal tissues
