Filter by:The aim of this study is to use the combination of immune checkpoint inhibitor of Toripalimab, and chemotherapy agents of TP, as a neoadjuvant therapy to treat the patients with locally advanced OSCC, followed with radical surgery and post-operative radiotherapy/chemoradiotherapy, the major pathological response and safety will be evaluated as the primary surrogate endpoints, the 2-year survival rate and local recurrence rate will be the second endpoints.
Oral cancer starts in the mucosa of the mouth and the most common site is the tongue and gingiva. One of the most important issues for the prognosis is to surgically remove all the cancer, at the sides as well as at the deep margin. To accomplish that, it is crucial to identify the border between tumour and healthy tissue. Traditionally white light from a head light or operation theatre lamp is used to illuminate the area of the tumour. Narrow Band Imaging (NBI) is an optical technique where ordinary white light is filtered so only the blue light in it is used. Illuminating the mucosa with this blue light through an endoscope with high definition image, makes the blood vessels appear more clearly. The altered blood vessels that the cancer produce can thereby be seen and mark the area where the tumour starts. This study examines if NBI is helpful in the decision of where the border between the cancer and the normal mucosa is. If so, NBI might improve the possibility to remove all cancer tissue compared to using the ordinary white light. This study will also increase the knowledge about the NBI technique, which is helpful in the examination of patients with suspected head and neck cancers and at the follow-up of patients after treatment. Participants are patients with oral cancer presenting at the otorhinolaryngology department in Örebro University hospital in Sweden for surgical treatment. The surgery will be done in the usual fashion but the mucosa surrounding the tumour will also be illuminated by NBI and this picture of the vessels will be compared to the microscopic analysis by the pathologist, the so called PAD. Thereby we seek to compare the border in white light to the border seen with NBI.
In patients with locally advanced oral squamous cell carcinoma (OSCC), due to the large tumor burden and neck lymph node metastasis, comprehensive treatment is recommended, including surgery, radiotherapy, chemotherapy and others. Pre-operative inductive therapy can reduce tumor volume, increase organ retention rate, and reduce distant metastasis rate. Vascular endothelial growth factor (VEGF) receptor in head and neck squamous cell carcinoma is over-expressed and associated with disease invasion and poor prognosis. The use of targeted therapy against VEGF can not only inhibit tumor neovascularization, but also make the effectiveness of chemotherapeutic agents. VEGF and VEGFR are closely related to immune escape. Tumor growth requires new blood vessels to supply nutrients and oxygen, and VEGF can stimulate neovascularization. However, tumor neovascularization is often abnormal and distorted, which prevents immune active substances from reaching the tumor site. After tumor hypoxia, high expression of VEGF will induce tumor cells to express programmed cell death protein-1 (PD-1), which further leads to immune escape. Targeted drugs against angiogenesis can relieve immunosuppression to a certain extent, and theoretically have a synergistic effect with anti-PD-1 immunotherapy. The innovation of this study is the combination of immune checkpoint inhibitor, Camrelizumab, and targeted drug against VEGFR, Apatinib, as an inductive therapy to treat the patients with locally advanced OSCC, followed with radical surgery and post-operative radiotherapy/chemoradiotherapy, the major pathologic response and safety will be evaluated as the primary surrogate endpoints, the 2-year survival rate and local recurrence rate will be the second endpoints.
investigating the level of malondialdehyde (MDA) & nitric oxide (NO) in saliva in oral premalignant and malignant lesions in order to determine their diagnostic value for the malignant and potentially malignant lesions.
This is a monocentric, prospective, non-comparative phase II study with minimal risks and constraints. The study will aim to assess the curative treatment of radio-induced mucositis by photobiomodulation using LED lamp.
The purpose of the proposed research project is to evaluate and enhance the feasibility and acceptability of integrating a tele-mentoring component into the identification of oral lesions at the 6 dental clinics of Family Health Centers at NYU Langone (FHC), a Federally Qualified Health Center (FQHC) in Brooklyn, NY.
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.
In 2007, The World Health Assembly (WHA) adopted a resolution to prevent oral cancer. The resolution urged the member states to ensure that measures against oral cancer was integrated into a national cancer control program by engaging and train dental personnel in screening, early diagnosis and treatment. Oral cancer is a severe oral health issue as it is potentially fatal and is the 5-6 most common tumor with approximately 275,000 cases for oral and 130,300 cases for pharyngeal cancers, excluding nasopharynx, globally. In Sweden,1000 new cases yearly is discovered and it is increasing. The explanation is an aging population and an increase in tonsil and tongue cancers caused by HPV, especially in younger subjects. This is due to changing sexual habits. Tumors caused by tobacco and alcohol are constant. Despite the decreasing prevalence of smoking and certain smoking-associated cancers, an increased incidence of tonsillar cancer has been seen in both Finland and Sweden. High risk HPV (hrHPV) oral cancer is also increasing.
This study aimed to explore using an APP in post oral cancer surgery to affect patients' needs and quality of life. Methods Quasi-experimental Research Design used purposeful sampling from January 1 to December 31 of the Far Eastern Memorial Hospital oral maxillofacial surgery ward and the otolaryngology ward requirement met post-treatment oral cancer patients who agreed to participate. Self-administered structured questionnaires, including basic personal information, cancer needs table short version (CNQ-SF), head and neck cancer quality of life scale (EORTC QLQ-H&N35), were used to collect information. Results were statistically analyzed to understand the distribution of variables and their relationships. Scientific or Clinical Implication of the Expected Results Using an APP intervention in post-operative patients with oral cancer may be the better way to promote health and enhance one's quality of life.
When soft palate defects lead to palatal insufficiency, the patient's quality of life is affected by difficulties swallowing, hypernasality, and poor intelligibility of speech. If immediate surgical reconstruction is not an option, the patient may benefit from the placement of a rigid obturator prosthesis. Unfortunately, the residual muscle stumps are often unable to adequately move this stiff and inert obturator to properly restore the velopharyngeal valve function. The objective of this case report was to describe the use of a membrane obturator prosthesis that incorporates a dental dam to compensate for the soft palate defect.
