Filter by:Warburg effect is an important feature of tumors,and genetic variation is one of the main factors of individual differences to radiotherapy treatment response for nasopharyngeal carcinoma(NPC). Through the previous work investigators found that the p53 codon72 (Pro/Arg) was related to the prognosis of NPC; Using the method of proteomics, investigators discovered glycolysis related gene such as PGK1, ALDOA,was associated with radiosensitivity.Thus,with all the previous work,investigators hypothesize that the key gene polymorphisms in glycolytic pathway, such as p53 , influence the glycolytic pathway,which leads to differences in radiosensitivity of NPC. This projects will include 600 cases of patients with NPC to detect common glycolytic key genes polymorphisms. Besides,investigators correlate these factors with their radiosensitivity and prognosis.Then, prediction model will be established, and validation of the prediction model will be done. Using enzyme-labeling instrument ,comet assay and clonogenic assay,cytological experiments will further investigate the influence of key gene polymorphisms on the glycolysis efficiency and mechanism of radiation sensitivity.Thus,investigators could provide theoretical basis of individualized treatment for NPC.
This study evaluates the hyperfractionated IMRT in the treatment of patients with locally recurrent nasopharyngeal carcinoma. Half of participants will receive hyperfractionated IMRT, while the other half will receive conventional fraction IMRT.
Among all the head and neck tumors, nasopharyngeal carcinoma (NPC) has a high tendency of recurrence and metastasis. For the advanced NPC patients, chemoradiotherapy is the main way of treatment. Currently, chemotherapy with cisplatin (DDP) combines with 5-fluorouracil (5-FU) is the classic front line therapy for NPC. However, the abnormal richness of angiogenesis of tumor and blood supply in tissue caused by radiation therapy often decrease the effects of radiochemotherapy. Human recombinant vascular endothelial inhibitor (endostar) can improve the sensitivity to chemoradiation via selectively inhibiting the migration of endothelial cells and the formation of tumor vessels. Moreover, it would induce vascular remodeling and normalization of the tumor vasculature, which will effectively aid the delivery of oxygen and anticancer drugs. In sum, antiangiogenesis in combination with chemoradiotherapy will be a promising way of treatment for NPC. In this study, the first-treated patients with NPC (stage Ⅲ or Ⅳa) confirmed by pathology, and patients with recurrent and metastatic NPC will be randomly assigned to two groups (1:1): a trial group (DDP, 5-FU, endostar and sequential intensity modulated radiation therapy (IMRT)), and a control group (DDP,5-FU and sequential IMRT). Evaluations will be developed including progression-free survival (PFS), Overall response rate(ORR), overall survival (OS), adverse effects rate and quality of life. This research will provide more evidences of evidence-based medicine for the safety and tolerability of endostar and the clinical application of endostar in NPC treatment.
Several prospective randomized trials have demonstrated that concurrent chemoradiotherapy was superior to radiotherapy alone in the treatment of locoregionally advanced nasopharyngeal carcinoma (NPC). Based on these evidences, concurrent chemoradiotherapy (CCRT) with/without sequential chemotherapy has become the standard care for locoregionally advanced NPC. However, most of these evidences of standard treatment for locoregionally advanced NPC were based on the two-dimensional conventional radiotherapy (2DCRT). As the intensity-modulated radiation therapy (IMRT) technique has been widely used in the last decades, IMRT improved the treatment outcomes of patients with NPC, especially the local control rate. Currently, more retrospective studies compared the IMRT alone vs. IMRT plus concurrent chemotherapy, and reported that concurrent chemotherapy failed to improve survival rates for patients with locoregionally advanced disease, but increased the severity of acute toxicities. People started to reconsider the role of CCRT. Therefore, we propose this randomized phase III non-inferiority study to reassess the efficacy and contribution of concurrent chemotherapy in locoregionally advanced NPC during IMRT era.
This is a Phase II trial to study the effectiveness and security of cisplatin concurrent chemoradiotherapy plus TIL versus cisplatin concurrent chemoradiotherapy only with IMRT in treating patients with locoregionally advanced high risk nasopharyngeal carcinoma.
Nasopharyngeal carcinoma (NPC) is the tenth leading cancers in Taiwan and investigating its biomarker is important for understanding the mechanism of its pathogenesis.
The purpose of this study is to understand the role bacteria that normally live in the colon may play in colorectal cancer risk, in addition to the hereditary risk to colorectal cancer. The investigators will collect stool specimens as well as additional colon biopsy specimens during the patient's scheduled colonoscopy procedure. The investigators will also collect a questionnaire about diet and lifestyle. The samples will be used to study the impact of diet on naturally-occurring oral and gut bacteria and their influences on human health including risk of cancer.
Nasopharyngeal carcinoma (NPC) is a geographically endemic, Epstein-Barr virus (EBV)-associated carcinoma of epidermoid origin. It occurs most commonly in Southern China and Southeast Asia. The NPC cells are poorly differentiated or undifferentiated with a high incidence of lymphatic and hematological dissemination. Because of the inherent anatomic constraints and a high degree of radiosensitivity, radiotherapy (RT) has been the primary treatment for NPC patients. NPC is also a chemosensitive tumor. Various modes of combined chemoradiotherapy have been used to treat NPC patients with advanced-stage diseases during recent 20 years. However, treatment outcome for locoregionally advanced NPC is still unsatisfactory.
The standard treatment strategy for locally advanced (stage IVA) and metastatic (stage IVB) nasopharyngeal carcinoma has not been defined yet. Generally induction chemotherapy is given to those patients in order to shrink the tumor volume and facilitate the following radiation therapy. Thus, in this study, the investigators use the combination of Docetaxel+Cisplatin+Xeloda (DCX) to treat locally advanced and metastatic nasopharyngeal carcinoma patients, in order to evaluate the efficacy and safety profiles.
This is a phase 2 study to evaluate the efficacy of single-agent icotinib in patients with advanced nasopharyngeal carcinoma.
