Filter by:Tumours continually shed DNA into the circulation, where it can be accessed. This circulating tumour DNA (ctDNA) directly reflects tumour burden and has great potential to be a sensitive biomarker for treatment recurrence. These "liquid biopsies" could give a more real-time picture of the genomic status and evolution of a tumour and can be easily assessed for measurement of different biomarkers. However, in head and neck squamous cell carcinoma (HNSCC) patients treated with primary curative radiotherapy, data regarding ctDNA kinetics and its correlation with outcome are scarce. A new or additional tool for response evaluation next to or instead of conventional imaging after treatment would be beneficial to detect recurrences in an earlier stage, thereby increasing the chances of success of salvage therapy. More importantly, an early response parameter during treatment could help to identify patients that have a good treatment response and might benefit from treatment adaptation. With this study, we aim to reveal ctDNA as an effective tool for future dose (de)-escalation trials in HNSCC.
This is a phase I study, which tests the safety of different doses of lenvatinib in combination with cetuximab, to see which dose is the safest in people. This study will help find out if lenvatinib and cetuximab is a safe and useful combination for treating patients with HNSCC and cSCC.
This is a Phase 1, multiple dose, ascending dose escalation study to define a MTD/RD and regimen of XmAb20717, to describe safety and tolerability, to assess PK and immunogenicity, and to preliminarily assess anti-tumor activity of XmAb20717 in subjects with selected advanced solid tumors.
The study evaluates the effects of the drug Metformin on the oxygen content in cancer tissue. Low oxygen concentration in cancer tissue accelerates cancer growth. Moreover, the response to radiation therapy is worse when tissue oxygen is low, because radiation therapy depends on oxygen to unfold therapeutic effects. Metformin has been used to treat type II diabetes for over 50 years and features additional properties that could slow down cancer growth. One of these properties is the improved oxygen concentration in cancer tissue. This effect has been proven for various cancers. This study was planned to verify this effect in head and neck cancer. Patients who suffer from cancer of the mouth and are planned for surgical removal of the cancer will be given Metformin for 9 to 14 days. The tissue removed in the subsequent surgery will be compared to a tissue sample that had been taken from the same patient prior to Metformin intake. To evaluate the oxygen content in the tissue samples, the expression of genes that react to oxygen levels will be measured and compared between the samples taken before and after treatment with Metformin. A secondary aim is to evaluate whether changes in the oxygen content within the tumor can be visualized by means of magnetic resonance imaging (MRI). Therefore, participants undergo an MRI scan, before and after Treatment with Metformin. The changes in the MRI will be correlated to the changes measured in gene expression.
The purpose of this study is to examine how different messages about risk of melanoma can impact the way people protect themselves against developing these diseases.
Up to 31 subjects diagnosed with oral squamous cell carcinoma received one application of a permeation enhancer 3 treatment applications of a Cisplatin drug-loaded patch to the tumor site at each of the 4 treatment visits. These 4 treatment visits were scheduled to occur during the 3 weeks prior to the standard of care tumor resection. Funding Source: FDA OOPD
This is a phase 2, open-label efficacy study of VGX-3100 administered by intramuscular (IM) injection followed by electroporation (EP) in adult men and women who are human immunodeficiency virus (HIV) negative with histologically confirmed anal or anal/peri-anal high-grade squamous intraepithelial lesion (HSIL) associated with human papilloma virus (HPV)-16 and/or HPV-18. Approximately 24 participants will receive at least 3 doses of VGX-3100.
New tools are needed to 1) diagnose and 2) stage early esophageal squamous cell carcinoma (SCC) in order to improve outcomes of this frequent and lethal cancer. Optical coherence tomography (OCT) is an optical technique, which can image human tissue ex vivo and in vivo with a resolution around 30µm and with a depth of 1mm. Full-field optical coherence tomography (FFOCT) is a new modality, which allows to image an ex vivo specimen with a cellular resolution and to perform 3D reconstruction. This device has never been tested on esophageal specimens. Therefore, the aim of this non-interventional research is 1) to determine FFOCT diagnostic criteria for SCC and 2) to figure if FFOCT allows the staging of the depth of invasion in SCC. To achieve these goals, we will image ex vivo 10 specimens of endoscopic resection of SCC (endoscopic mucosal resection (EMR) and submucosal dissection (ESD)) using an FFOCT device and we will compare the results with histological analysis of these specimens.
Although recent global trends indicate reduced postoperative mortality after esophagectomy, major morbidity, in particular pulmonary, remains high, with considerable health and economic costs. In a recent modern international collaborative series of 2704 patients from high-volume centers, with an approximate equal mix of open and minimally invasive approaches, respiratory complications were evident in 28% of patients, pneumonia in 15%, and respiratory failure in 7%.1 In other series, respiratory failure is reported in up to 15% of patients and is the most common cause of mortality. Prediction of risk and prevention of respiratory morbidity is therefore of considerable importance, and in this context baseline assessment of respiratory physiology compliments clinical assessment, history and enhanced recovery pathways representing key elements of current patient management. In this study, which will include all prospective patients with locally advanced esophageal cancer treated at a National Center, pulmonary function will be systematically measured before and after neoadjuvant therapy. The investigators seek to evaluate the incidence of radiation induced lung injury (RILI), as well as subclinical changes in pulmonary physiology that may be linked to postoperative complications, and quality-of-life in survivorship, and to compare cohorts who received radiation therapy or chemotherapy alone, preoperatively.
This phase I trial studies how well stereotactic body radiation therapy works in combination with tremelimumab and durvalumab in treating participants with cervical, vaginal, or vulvar cancers that have come back (recurrent) or spread to other areas of the body (metastatic). Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. Immunotherapy with monoclonal antibodies, such as tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving stereotactic body radiation therapy, tremelimumab, and durvalumab may work better in treating participants with cervical, vaginal, or vulvar cancers.
