Filter by:Squamous cell carcinoma (SCC) could be a very aggressive cancer and has a bad prognosis if not detected early and thus is associated with high mortality. The development of simple and reliable biomarkers for the early detection of SCC is one of the solutions to better diagnose, treat these tumors, evaluate and monitor treatments, and hence reduce mortality. In a previous work, the investigators demonstrated the ability of Proton Magnetic resonance spectroscopy (1H-MRS) to non-invasively assess spectroscopic and metabolic profiles of tongue tissue in healthy subjects. In the present work, the investigators challenge the use of in-vivo 1H-MRS as a potential method for non-invasive metabolic monitoring of patients with squamous cell carcinoma of the tongue undergoing therapy. Thus the main objective is to study the spectroscopic and metabolic differences, e.g. including variation in the metabolite TMA-Cho (trimethylamine-choline), of tongue tissue between healthy subjects and in patients with squamous cell carcinoma of the tongue, before and after surgery.
Regarding oral cavity cancer, the high incidence of neck metastasis along with its impact on survival and prognosis are in favor of elective neck dissection. Moreover, occult metastases could develop at lower levels in the neck (levels IV-V) Regarding the tongue, the rate of skip (occult) metastasis involving unremoved level IV cervical lymph nodes in squamous cell carcinoma of the tongue ranges from 0 % - 11.4 %. However, no data is available or a correlation between the risk of level IV involvement and the affection of specific tongue subsites or a certain cutoff value of tumor thickness.
Complete removal of cancer encircled by a secure margin of healthy tissue is the aim of surgical oncology. A close or positive surgical margin reported by pathologist typically ends in adjuvant therapies (re-surgery and/or radiotherapy), which come with prognostic risks and financial cost. Therefore, ex-vivo imaging of removed cancer tissue may assist in margin evaluation. In this study, investigators aimed to investigate the correlation of 3D ultrasound to histopathology to assess tongue tumor margin status.
This phase I trial studies the side effects of image-guided hyper-fractioned proton therapy in treating patients with head and neck cancer that has spread to nearby tissue or lymph nodes (locally advanced) and cannot be removed by surgery (unresectable). Radiation therapy uses high energy protons to kill tumor cells and shrink tumors. The change in dose radiation frequency and dose investigated in this study may help to better control the tumor and prevent it from coming back or growing. The goal of this study is to test a new radiation schedule that administers more radiation to the tumor tissue using image guided proton therapy for patients that have a high risk of having a tumor recurrence (the tumor comes back after treatment).
The evidence of swallowing changes in tongue cancer patients receiving mandibular-lip split or pull-through resection surgeries is still limited. This study aimed to investigated the swallowing changes in these patients by using the videofluoroscopy (VFSS) and high resolution impedance manometry (HRIM).
A prospective multicenter randomized non-inferiority clinical trial, to evaluate the efficacy and safety of 1.0 cm-safety margin surgery, compared with 1.5 cm safety margin surgery for cT1-2N0 oral tongue cancer Summary: A current standard primary treatment for oral tongue cancer is a curative surgical resection with/without adjuvant radiation treatments (or chemoradiation). In pathological analysis of surgical specimens, more than 5 mm of non-tumorous tissues from the tumor border is regarded as a safe negative resection margin, according to the NCCN guideline (the National Comprehensive Cancer Network, Dec 10. 2020). To achieve this clear margin, surgeons are apt to use a 1.0 to 1.5 cm safety margin around the gross tumor during surgery, considering 30-50% tumor shrinkage in tissue fixation process. Many previous retrospective data have been reported to suggest the optimal or proper surgical extent for oral tongue cancer. Wider resection can lead to better local control, however, it sacrifices more normal tissue, resulting in the functional deficit of tongue (speech and swallowing), even with reconstruction. Unfortunately up to now, no prospective comparison of a different surgical safety margin for oral tongue cancer have been conducted to draw a more solid conclusion. Particularly in early stage oral tongue cancer (cT1-2N0), some study results have suggested that less than 5 mm resection margin in pathology specimens can be also safe and effective in terms of tumor control. To achieve a well-grounded result about the proper surgical safety margin in early stage (cT1-2N0) oral tongue cancer, we will compare the outcomes of the two (1.5 cm versus 1.0 cm) surgical safety margin in curative resection for cT1-2N0 oral tongue cancer.
This is a multi-center, open-label, dose escalation study to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, and maximum tolerated dose (MTD) of QBS10072S in patients with advanced or metastatic cancers with high LAT1 expression. The MTD of QBS10072S will be confirmed in patients with relapsed or refractory grade 4 astrocytoma.
Radiotherapy of tongue cancer is associated with acute and late morbidity. Use of an intraoral stent will provide a larger distance between the tongue and palate and can reduce side-effects. The aim of the present study is to confirm that an intraoral stent will give lower dose to the palate throughout the treatment period.
This study aims to verify the impact of four speech therapy sessions on the Quality of Life of patients treated for malignant tongue and/or jaw cancer, using as measure specific questionnaires of speech and swallowing. The hypothesis is that after treatment with exercises and speech therapy guidance, patients will present better indicators on Quality of Life related to speech and swallowing.
The purpose of this study is to investigate if ultrasound can be helpful in the diagnostic work-up of oral tongue and floor of the mouth cancer. One important factor is how deeply the tumour invades the tissue, the so called depth of invasion (DOI). The investigator will measure DOI with ultrasound and compare the result with the same measurement by magnetic resonance imaging and the microscopic result after the surgery (PAD). Ultrasound will also be used during surgery of the tumour to investigate if it is useful to better decide the depth of the tumour and thereby improving the operation.
