Filter by:Importance: There are no global screening recommendations for esophageal squamous cell carcinoma (ESCC). Endoscopic screening has been investigated in high incidence areas of China since 1970's. But up until now there no apparent evidence that would lead to a reduction in disease morbidity and mortality. Objective: To evaluate whether endoscopic screening and early intervention program could reduce the incidence or mortality of ESCC. Design: Community-based, controlled cohort study among 45 386 residents, Endoscopy screening was completed from November 1999 to May of 2000. Subjects in intervention group were examined once during intervention period. The study follow-up concluded in December 2009. Setting: High risk area of ESCC in China Participants:Cluster sampling from communities with high rates of esophageal cancer. A set of villages with was selected as the study intervention community. Age 40 to 69 years residents were selected as an eligible population. Another set of villages was select as the control population. Buffer villages were set up between intervention and control group. Intervention: Endoscopy with Lugol's iodine staining and early treatment on precancerous lesions was undergone for the intervention group. Main Outcome(s) and Measure(s): Incidence and mortality ESCC
The treatment of squamous cell carcinoma of lung has not improved suffuciently. Nedaplatin is a second-generation platinum compound that is more active against squamous cell carcinoma of the lung with a response rate of 60%, issued by the finished Phase II trial in Japan.
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.
This is an investigator initiated phase II study to assess the efficacy of a chemotherapy called nab-paclitaxel as first line cytotoxic chemotherapy in subjects with unresectable locally advanced or metastatic cutaneous squamous cell carcinoma (SCC). All subjects receive the treatment by vein weekly and receive the same dose of the treatment. The risk of developing cutaneous SCC is approximately 10% in a lifetime. The vast majority are treated surgically and do not recur. However a small percentage become unresectable over time or metastasize distantly in the body. Unresectable and metastatic cutaneous SCC has a poor prognosis and oncologists often choose a whole body therapy without the benefit of prospective efficacy data. Very little prospective investigation into the efficacy of specific chemotherapy regimens as a function of line of therapy has been performed in this patient population. Nab-paclitaxel is type of chemotherapy that has demonstrated activity in other types of cancer such as lung and head and neck cancers. The primary objective of this study is to determine the response rate (percentage of subjects with tumor shrinkage) to nab-paclitaxel treatment in subjects with cutaneous SCC who have not received cytotoxic chemotherapy in the unresectable or the metastatic settings.. Secondary objectives are the progression free survival (time until tumor starts to grow), safety, assessment of the percentage of subjects whose tumor expresses a protein called SPARC, and correlating the expression of SPARC with response to treatment. To determine if the tumor expresses SPARC part of a prior standard biopsy such as that performed to establish the diagnosis of SCC will be used. SPARC is a protein that is overexpressed in a range of different cancer types and may alter the environment around the tumor possibly in a way that may make the SCC more responsive to treatment with nab-paclitaxel.
In general, patients with Human Papilloma Virus Positive Oropharyngeal Squamous Cell Carcinoma (HPVOPC) are curable, young and will live for prolonged periods. They are at high risk for long-term toxicity and mortality from therapy. While the long-term consequences of chemotherapy and surgery for head and neck cancer are relatively constrained, high-dose radiotherapy (RT) and chemoradiotherapy (CRT) substantially impact on local tissues and organ function and result in a significant rate of late mortality and morbidity in patients. Studies are now being designed to reduce the impact of RT and CRT for patients. Patients with intermediate stage HPV positive oropharyngeal cancer will be screened for poor prognostic features and undergo robotic surgery. Patients in whom pathology demonstrates good prognosis features will then be followed without postoperative radiotherapy. Patients with subsequent recurrence will be treated with either surgery and postoperative radiotherapy or postoperative chemoradiotherapy alone. Patients with poor prognostic features (ECS, LVI, PNI) will receive reduced dose radiotherapy or chemoradiotherapy based on pathology. It is expected that over 50% of patients treated with surgery will have had a curative treatment and will avoid radiation therapy entirely and long-term survival will not be changed by withholding radiation therapy to good prognosis patients after surgery. There are exploratory biomarkers of risk of recurrence that will be collected and studied. There are currently few trials examining the role of de-escalation using surgery alone in intermediate and early T-stage HPV related disease. New surgical techniques have broadened the range of patients capable of achieving a complete resection and the functional outcomes in such patients are outstanding. Furthermore, the sensitivity of HPVOPC to chemotherapy and radiotherapy raise the possibility that delayed or salvage treatment in early stage patients would be highly effective, would result in similar survival outcomes and radiotherapy could be applied to a much smaller population then current standards call for. Looked at from a different perspective, the need for post-operative radiotherapy in this younger, HPV+ and more functional population has not been validated in clinical trials to date.
This phase II trial studies the effects of interstitial photodynamic therapy in patients with head and neck cancer that has come back. Interstitial photodynamic therapy uses a combination of laser light and a light-sensitive drug called porfimer sodium to destroy tumors. During treatment a laser light is used to activate the drug. Interstitial photodynamic therapy may be an effective treatment for head and neck cancer.
Primary Objective: To evaluate the overall response rate (including complete response and partial response) of subjects treated with combination therapy docetaxel and cisplatin followed by the chemoradiotherapy in patients with locally advanced head and neck cancer Secondary Objective: To assess the safety and tolerability of combination therapy docetaxel and cisplatin followed by the chemoradiotherapy in patients with locally advanced head and neck cancer
SmartMatrix™ is a single layer dermal replacement scaffold for full thickness skin replacement. The scaffold consists of a porous matrix of cross-linked human fibrin plus alginate that has been designed and optimised to facilitate wound closure and healing through cellular ingress and rapid growth of new blood vessels. This proof of concept study will involve patients with surgical wounds resulting from the excision of basal cell carcinoma (BCC) and squamous cell carcinoma SCC).
The objective of the current proposal is to determine if concentrated beet root could improve medical treatment compliance as defined by completion of radiotherapy and 3 cycles of chemoradiation without dose reduction, preserve fat-free mass, and strength while reducing mucositis. The investigators central hypothesis is that dietary nitrate supplementation in head and neck cancer patients receiving aggressive medical care will improve compliance with medical treatment by attenuating the loss of muscle mass and strength and reducing symptoms (mucositis) associated with treatment compared to patients receiving standard care with placebo.
The aim of this trial is to examine the addition of docetaxel on disease progression, metastasis and survival of patients otherwise treated with SBRT and cetuximab alone. To better resolve the impact of the experimental treatment the presence/absence of prior cetuximab treatment will be determine before assigning treatment to either cetuximab and SBRT only or cetuximab, SBRT, and docetaxel.
