Filter by:The aim of this study is to compare the effectiveness and safety of spraying Lugol's solution from cervical esophagus to esophagogastric junction (downward) and from esophagogastric junction to cervical esophagus （upward）during chromoendoscopy.
Single arm phase II trial designed to assess the efficacy of durvalumab treatment in terms of 6-month progression-free survival. We will include 22 patients who will receive 1500 mg durvalumab (MEDI4736) via IV infusion Q4W <<for up to a maximum of 12 months (up to 13 doses/cycles) with the last administration on week 48>> or <<until confirmed disease progression>> unless there is unacceptable toxicity, withdrawal of consent, or another discontinuation criterion is met. If a patient's weight falls to 30 kg or below for 1 week or longer ( ≥ 7 days) durvalumab will be permanently discontinued.
Clinical studies related to immunotherapy of HNSCC have shown that PD1 monoclonal antibody has better clinical benefits than conventional chemotherapy. This phase II clinical study is a single arm, open, single-center study. The aim of this study is to observe and evaluate the efficacy and safety of Sintilimab combined with paclitaxel-albumin-binding for injection in patients with advanced recurrent and metastatic HNSCC who fail to receive first-line or more treatment. Participation in this study for treatment may benefit patients with advanced recurrence or metastasis of HNSCC.
Overall survival of patients with head and neck squamous cell carcinoma (HNSCC) remains unsatisfactory due to often advanced clinical stage at diagnosis and high rate of recurrence and second primaries. About 75 % of patients with localized HNSCC are expected to show circulating tumor DNA (ctDNA) pre-treatment. ctDNA reflects tumor genome and disease burden and is termed 'liquid biopsy' (LB) when collected through venous bloodstream. LB has potential to assist in early diagnosis of recurrence and progression, and prediction of response to targeted therapeutic agents. Increased metabolic activity measured in positron emission tomography-computed tomography (PET-CT) is currently the most sensitive technique to detect residual cancer or progression of HNSCC after curative treatment. High metabolically active tumor volume (MTV) is associated with treatment resistance and shows independent prognostic significance. The objective is (i) to investigate whether MTV detected with PET-CT correlates to the pattern and amount of genetic alterations in ctDNA of patients with HNSCC referred to radio- (chemo)therapy (RT/CRT). Another objective is (ii) to determine sensitivity of LB compared to PET/CT in detecting residual tumor 3 months after completion of RT/CRT. Third (iii), genetic landscape in LB and fresh tumor samples will be evaluated to detect resistance genes and targets for immunotherapy and surveillance post-treatment. This prospective study includes 30 patients with stage III/IV HNSCC. Before onset and 3 months from RT/CRT, LB is obtained for next-generation DNA sequencing using a commercial platform. ctDNA and digital droplet PCR will be quantified and compared to MTV in simultaneously acquired PET-CT. The investigators hypothesize that LB could assist or replace PET/CT in response monitoring and detection of recurrence after RT/CRT.
Esophageal cancers are the seventh most common cancer in the world and one of the most common causes of cancer deaths. In some parts of China, the incidence of SCC is among the highest in the world. Despite surgery and adjuvant radiotherapy, the prognosis for SCC patients was disappointing. There is therefore an urgent need for new prevention and treatment strategies. Epidemiological investigations have found that about 25% of human tumors are associated with chronic inflammation caused by a variety of causes, and chronic inflammation activates nuclear transcription factors (nuclear Factor,NF), induces gene and epigenetic changes such as DNA methylation, tumor suppressor gene point mutations, and post-translational modification, and participates in the process of tumorigenesis. It has been noted that the long-term regularity of the use of non-steroidal anti-inflammatory drugs aspirin can reduce the incidence and mortality of a variety of tumors, including esophageal cancer. Aspirin is the earliest, most extensive and common antipyretic analgesics and anti-rheumatism drugs used to play an anti-inflammatory role by inhibiting the synthesis of PGs. COX-2 is a key enzyme in the synthesis of PGs, so it is speculated that the anti-tumor effect of aspirin inhibits the PGs of COX and its inhibition.
The purpose of this study is to assess the efficacy and safety of apatinib plus concurrent neoadjuvant chemoradiotherapy in patients with esophageal squamous cell carcinoma.
There is reason to believe that hyperbaric oxygen administered immediately prior to radiotherapy will prove beneficial for this cancer type and stage. The basis for this hypothesis is a review of several decades of published work, the conclusion of a recent (2018) Cochrane Review, and results of a Phase I trial.
Does the tumor thickness value of buccal squamous cell carcinomas, predict cervical nodal metastasis in clinically and radio-graphical neck negative (N0) thus sparing such patients unnecessary surgical procedures and it's associated morbidities? The aim of the study is to evaluate the prognostic value of tumor thickness cut off 4 mm in predicting cervical nodal metastases in a population of Egyptian patients presenting with Buccal Squamous Cell Carcinoma. The hypothesis is that patients with tumor thickness less than 4 mm will present with significantly less cervical nodal metastasis.
This is an open-label phase II trial investigating the effect of metformin in combined with cisplatin plus paclitaxel as neoadjuvant therapy with advanced esophageal squamous cell carcinoma.
The purpose of this study is to observe and evaluate the efficacy and safety of SHR-1210 vs placebo as consolidation chemotherapy after radical concurrent chemoradiotherapy for unresectable locally advanced ESCC.
