Active clinical trials for "Squamous Cell Carcinoma of Head and Neck"

To determine if combined [18F]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT) is performant enough with respect to detecting residual lymph node involvement after chemoradiation in order to omit planned neck dissections in patients with locally advanced potentially operable, N2 and N3 head and neck squamous cell carcinoma (HNSCC). Primary study hypothesis: The lower bound of the 95% confidence interval (CI) of the negative predictive value (NPV) of FDG PET/CT to detect residual malignant lymph node involvement at 12 weeks after completing chemoradiation will exceed 85%.

This study is a retrospective real-world study. In this study, we plan to collect the clinical data of LASCCHN patients who received chemoradiotherapy combined with or without nimotuzumab .

The purpose of this study is to test the accuracy of toluidine blue in the assessment of intraoperative tumor margin after excision of oral squamous cell carcinoma(OSCC)in comparison to H&E stain on frozen section.

The roles of imaging in cancer may be divided into that of diagnosis and tumour detection, staging and assessment of response to treatment. Standard radiological techniques include ultrasound, Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET). A combination of imaging techniques is often necessary to differentiate between cancerous and normal tissue. Traditional imaging techniques identify cancers by their gross appearance and structural/ cellular characteristics, whilst PET do so by tracking glucose metabolism. PET owes its specificity to the high rate of glucose metabolism seen in most cancers. However it is not used routinely due to a lack of availability and high costs. In addition, PET is often used in combination with CT, which imparts a significant diagnostic radiation dose. This can increase an individual's risk of cancer, especially with childhood or early adult exposure. In contrast, MRI is more readily available and does not involve radiation. However its ability to detect cancer by tracking glucose metabolism has not been widely explored. Our group has recently developed a novel MRI technique called Gluco-CEST that can image glucose delivery, uptake and metabolism in cancer, therefore potentially allowing a radiation-free, one-stop imaging service that can be adapted to current generation of MRI scanners. This study aims to optimise the GlucoCEST technique, after which it will be rigorously tested and compared to standard imaging parameters and clinical or pathological reference standards to evaluate its diagnostic and predictive power across a number of cancer populations.

Head and neck cancer (HNC) continues to be a significant health care problem in Taiwan and oropharyngeal squamous cell carcinoma (SCC) is the common subtype. With the concern of organ preservation in recent years, concurrent chemoradiation is the major treatment modality for oropharyngeal SCC, while endoscopy with biopsy serves as the main diagnostic tools. With the advance of MRI technology, whole body MRI is now possible, and functional techniques become more feasible in the head and neck region, including diffusion-weighted imaging (DWI) which comprises of monoexponential DWI, intravoxel incoherent motion (IVIM) model and Kurtosis (biexponential or non-Gaussian fitting), and dynamic contrast-enhanced perfusion weighted MRI (DCE-PWI) become feasible. Therefore, MRI can evaluate distant site status of HNC in the single examination session and provide biologic information of tumors. Positron emission tomography/CT (PET/CT) is another common imaging modality to evaluate HNC, because of its ability to provide whole-body anatomic and metabolic information. Integrated PET/MRI is a novel imaging technology that combines PET and MRI in one single scanner. In this 3-year prospective study, the investigators will take the advantages of integrated PET/MRI scanner with DWI (including monoexponential, kurtosis and IVIM modes) and DCE-PWI to evaluate our 160 patients with oropharyngeal SCC subjected to chemoradiation. Non-contrast chest CT will also be performed on the same day. The investigators aim to determine whole-body staging/restaging accurately, to predict treatment response and prognosis, and to determine necessity of noncontrast chest CT. The investigators expect that this project will offer the validation of usefulness of integrated PET/MRI in tumor staging/restaging of oropharyngeal SCC and resultant clinical impact. The role of noncontrast chest CT in the workup with our PET/MRI protocol can be defined. It will also provide evidence about how and to what extent the various simultaneously acquired MRI and PET functional parameters can help prediction of treatment response and prognosis of oropharyngeal SCC subjected to chemoradiation, which are important in timely modification of treatment regimen.

This study was designed to verify the role of salivary LINC00657 as a diagnostic marker in oral squamous cell carcinoma (OSCC) patients as compared to oral lichen planus (OLP) (as an example of oral potentially malignant lesions) and normal individuals, and to show its relation to miR-106a. A total of 36 participants were included.

This is a prospective, observational, non-interventional, multicenter, post-marketing surveillance study to mainly collect safety information from subjects with locally advanced and recurrent/metastatic Squamous Cell Carcinoma of Head and Neck (SCCHN) treated with cetuximab based on the locally approved label.

Surgery remains a main pillar in the treatment of head and neck squamous cell carcinoma (HNSCC). The margin status is the main prognostic factor of local tumor control in surgically treated HNSCC and will determine the postoperative treatment strategy. A margin of ≤1 mm of normal tissue is considered a positive margin and requires either a re-operation or postoperative chemoradiation with a combination of cisplatin and 5-FU, which substantially increases morbidity. Margins wider than 1 mm but less than 5 mm require re-operation, or, if that is not possible, post-operative radiotherapy without the concomitant use of chemotherapy. Currently, no technology is available in the operating room, which reliably supports tumor excision in terms of margin status. In fact, surgeons can only combine pre- operative imaging data with tactile and visual information during surgery for assessing tumor margins with limited accuracy. With the introduction of molecular imaging techniques using near infrared (NIR) fluorescent optical contrast agents coupled to targeted compounds, new avenues have opened up for intra-operative assessment of tumor margins. Tracers are based on antibodies directed against Vascular Endothelial Growth Factor-A, i.e. bevacizumab-IRDye800CW, in patients with breast cancer or against Epidermal Growth Factor Receptor, i.e. cetuximab-IRDye800CW, in patients with HNSCC. First trials have shown that systemic administration of these compounds is safe and tumor specific. These findings prompted us to design this innovative application in a clinical trial for the intraoperative assessment of tumor margins during surgical treatment of HNSCC using cetuximab-IRDye800CW.

The aim of the current study is to assess the validation of Bmi-1 detection at both protein and molecular levels in oral epithelial dysplasia and oral squamous cell carcinoma as a biomarker for early cancer detection versus biopsy embedded in paraffin blocks.

Primary objectives: Evaluate the feasibility of rapidly accruing 30 participants with recurrent metastatic head and neck squamous cell carcinoma for the development of patient derived xenographs (PDX) from fresh, real time biopsies in which sensitivity to < 4 Ontario funded chemotherapeutic regimen will be tested. Written feedback to the primary oncologist will be provided. There is also a curative intent cohort of 30 participants undergoing surgical resection with curative intent. These PDX models will undergo exome sequencing with written feedback. Feasibility in both surgical and recurrent cohorts will be a measure of i) engraftment rate, ii) patient status at the time of drug testing completion and iii) rate of accrual.
