Filter by:Esophageal cancer is a common and fatal malignancy. It is the eighth most common incident cancer and the sixth leading cause of cancer death in the world. In Taiwan, esophageal cancer was newly diagnosed in 2199 patients and was the cause of 1507 deaths in 2011. Squamous cell carcinoma is the predominant histological tumor type, accounting for about 90% of the cases. Esophageal squamous cell carcinoma (ESCC) is an aggressive disease, characterized with extensive local growth and frequent metastases. Concurrent chemoradiotherapy (CCRT) with or without surgery is the treatment option for locally advanced ESCC. Further, target therapy is used in conjunction with CCRT and surgery in ESCC since several years ago. However, the therapeutic outcomes are not satisfactory due to the emergence of chemo-radioresistance. It is imperative to investigate new biomarkers and to find novel treatment targets in ESCC. A small population of tumor-initiating cells or cancer stem cells (CSCs) possess some biological functions like normal stem cells, including self-renewal, asymmetric cell division, slowly proliferation rate and drug-resistance. CSCs from many primary tumors and cell lines express specific stem cell markers, including Oct4, Sox2, Nanog, CD133 (promimin-1), Nestin, CD44 ,CD24, ALDH (Aldehyde dehydrogenase) and c-Kit. There are many evidences that CSCs are responsible for tumor initiation, progression and metastasis. CSCs are also believed to have important roles in cancer recurrence due to their resistance to anti-cancer drugs and radiation. CSCs express high levels of ATP-binding cassette (ABC) transporters. ABC transporter can pump cytotoxic drugs out of cells and is one important mechanism of multidrug resistance in CSCs. In addition, CSCs have high reactive oxygen species (ROS) scavenger expression to remove ROS produced from irradiation therapy. Fursultiamine (also known as thiamine tetrahydrofurfuryl disulfide, TTFD) is a derivative of vitamin B and currently used for nutrition supplement. The investigators have identified that Fursultiamine suppressed OCT-4, SOX-2, NANOG expression and decreased ABCB1 and ABCG2 in tumor sphere of ESCC cell lines. In this project, the investigators will conduct a prospective phase II study to investigate the effect of Fursultiamine combined with CCRT in ESCC patients. Stem cell markers in clinical specimens collected before and after CCRT will be evaluated.
This phase II trial studies how well sapanisertib works in treating patients with lung cancer that is stage IV or has come back (recurrent) and has a mutation in the NFE2L2, KEAP-1, or KRAS gene. Damage to these genes may cause the cancer to grow. Sapanisertib may stop this from happening by blocking enzymes.
The purpose of study is to assess the safety and performance of EktoTherix™ Tissue Repair Scaffold in the treatment of full-thickness, dermatologic wounds created by the surgical removal of non-melanoma skin cancers. EktoTherix™ is a medical device developed by Neotherix Limited, manufactured by the polymer processing technique of electrospinning. Described as a "tissue scaffold", EktoTherix is placed into the surgical wound to help the patients' own cells repair the wound, enhancing healing and improving quality (including cosmetic outcome). The tissue scaffold is completely absorbed by the body during the healing process, which means that there is no need to remove it when the wound is healed. All patients recruited into this study are treated with EktoTherix, are seen weekly until they heal and seen again at the final follow-up visit three months post-surgery. The investigators hypothesise that the use of EktoTherix will increase incidence of complete healing and result in an overall better cosmetic result of the healed wound.
Esophageal cancer is the sixth leading cause of cancer death in worldwide. Over the past 2 decades, well-designed clinical trials have documented the clinical benefits of combination of chemotherapy and radiation for localized esophageal cancer, either as primary therapy or in neoadjuvant setting. Paclitaxel, a radiation sensitizer, has important single-agent activity in esophageal cancer. Paclitaxel-based chemoradiation has been the framework for the recent Radiation Therapy Oncology Group (RTOG) trials of nonoperative management of esophageal cancer. Accumulating clinical evidence suggests that Epidermal Growth Factor Receptor (EGFR) represents a viable target in the treatment of esophageal cancer. EGFR expression is associated with poor prognosis. Nimotuzumab binds specifically to EGFR on both normal and tumor cells and competitively inhibits the binding of Epidermal Growth Factor (EGF) and other ligands, such as Transforming Growth Factor-α (TGF-α). Preclinical models have suggested synergy between nimotuzumab, paclitaxel, cisplatin and radiation. For our phase II study in locally advanced esophageal squamous cell carcinoma (ESCC), the combination of cetuximab and chemoradiotherapy has demonstrated both response and survival benefits. Myara et al reported that nimotuzumab plus concurrent chemoradiation therapy (CCRT) was safe and provided statistically significant objective response (47.8%) and disease control rate (60.9%) in nonresectable ESCC. With all these, the investigators plan to study phase III trial.
Patients with locally advanced rectal and esophageal carcinomas typically undergo neoadjuvant chemoradiation therapy prior to surgical resection. While response rates to this treatment differ among these three cancers, generally 20-25% of patients exhibit minimal or no response to preoperative chemoradiation therapy while 20-30% exhibit a complete pathologic response, and the remainder receiving a partial response. This will be a multi-center study of patients with newly diagnosed rectal adenocarcinoma, or anal squamous cell carcinoma (SCC) who will undergo neoadjuvant chemoradiation prior to surgery. The tumor from these patients will be tested to determine whether response to neoadjuvant chemoradiation can be accurately predicted.
This is a randomized, prospective, multicenter study.
The effect of neo-adjuvant chemotherapy on survival of patients with thoracic esophageal squamous cell carcinomas remains the most controversial part of neo-adjuvant therapy for esophageal carcinomas. One of our objectives is to evaluate whether the neo-adjuvant therapy with cisplatin and paclitaxel followed by right thoracic approach esophagectomy with total 2-field lymph node dissection improves the overall survival of thoracic esophageal cancer patients.
This phase I trial studies the side effects and best dose of stereotactic body radiation therapy (SBRT) in treating participants with head and neck cancer that has spread from where it started to nearby tissue or lymph nodes and is at high risk for continuing to spread because the participant cannot undergo standard chemotherapy. Stereotactic body radiation therapy is a specialized radiation therapy that delivers radiation directly to the tumor in smaller doses over several days, which may kill more tumor cells and cause less damage to normal tissue.
The primary object of this trial is to evaluate the 2-year local control rate adding extensive clinical target volumes in postoperative radiotherapy for esophageal squamous cell carcinoma.
This study will assess the efficacy of LLLT to mitigate and ameliorate the acneiform-rash, radiation dermatitis, and pain, while assessing its impact on patient reported quality of life.
