Filter by:Cluster-randomized controlled trial in Trivandrum district, Kerala, India to evaluate the effect of triennial screening for oral cavity cancer using visual inspection on oral cancer mortality.
This study will be conducted to obtain data on oral cancer risk factors to generate machine learning models with good predictive accuracy for stratifying individuals with high-oral cancer risk and delineating high-risk and low-risk oral lesions. Likewise, this study will seek to provide oral cancer-related health education and training on oral-self-examination for beneficiaries
Patients with head and neck cancer and undergo neck dissection often suffer from spinal accessory nerve dysfunction (e.g. shoulder droop, shoulder pain, and decreased active range of motion (AROM) of the shoulder joint and scapular muscle strength), even the spinal accessory nerve is preserved during surgery. Abnormal muscle activities of scapular muscles, including upper trapezius (UT), middle trapezius (MT), lower trapezius (LT), serratus anterior (SA) and rhomboid were reported in subsequent research articles. Particularly for the trapezius muscle, the decreased amplitudes were observed even after 9 months of neck dissection. It has been reported that conscious correction of scapular orientation during arm movement could increase trapezius muscle activities, and motor control training could change scapular kinematic such as increased posterior tilt and upward rotation during arm movement.
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.
The purpose of this voluntary research study is to learn about the potential effects that black raspberry (BRB) lozenges may have on reducing the damage caused from cigarette smoke in mouth cells in adult smokers, which may be useful in reducing health risks associated with smoking.
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.
Background: Due to the complex treatment modalities and long-term side effects, oral cancer (OC) patients might suffer from psychological and physical distress and be unable to return to work (RTW). Purposes: This is a two-phase study. First, the investigator aims to validate a scale about OC patients' perception of RTW and identify those concerns in RTW. Second, the investigator aims to (1) develop the contents of a "Personalized Survivorship Care Plan- Oral Cavity Cancer (PSCP-OC)" and (2) examine the short and long-term effects of PSCP-OC on patients' physical function (symptoms, muscle strengths, fitness, nutrition status), psychological distress (depression, fear of cancer recurrence) and RTW. Method: First phase, the investigator will modify and validate the "Illness Perception Questionnaire (IPQ)" with adding the head and neck cancer specific items (modified IPQ-mHN) to assess the barriers of RTW in OC patients. The investigator will recruit 300 subjects in this phase to test the IPQ-mHN psychometrics. The second and third year will develop and test the PSCP-OC intervention. Eligible subjects will be (1) newly diagnosed OC patients with surgery, and (2) who are at work in time of diagnosis. A stratified randomization by cancer stage would be conducted. Both groups will receive baseline assessment before first intervention. PSCP-OC is a 6-month intervention which includes two parts: General module and Personalized module (150 subjects for each group). Ex group will receive the first PSCP-OC before discharge and 3 times face-to-face PSCP-OP once a month in the first three month after discharge and 3 times telephone physical-psycho-education interventions in month 4-6. Control group will receive regular and cancer case manager cares for 6 months. Each group will be followed for 12 months and assess of their outcomes at 6 time points: baseline (pre-discharge) and 1, 3, 6, and 12 months after surgery. Outcomes will be evaluated by physical distress, muscle strength, nutrition status, and length of time of RTW since completion of last major treatment. Results would be analyzed mainly by GEE. IRB approval will be received before the RCT. Expected Outcome: Expecting to develop a scale to identify those barriers preventing OC patients' RTW and further to test the PSCP. A promising result will further apply into clinical care to prevent or decrease the potential declined physical and psychological functions, increase their strength and help them RTW.
