The objective of this study is to assess the efficacy of induction chemotherapy followed by transoral surgical treatment and neck dissection, in definitive management of moderately advanced oropharyngeal squamous cell carcinoma. The surgical treatment will carry out Transoral Robotic Surgery (TORS) or Transoral Laser Microsurgery (TLM) for the primary tumor, and neck dissection for the management of cervical lymph nodes. The primary outcome measure will be disease specific survival (DSS). The secondary oncologic outcome measures will be locoregional control, relapse free survival, overall survival, and Quality of Life (QOL).
Surgical site infections are an important health indicator for hospitals and a significant medico-economic issue. The aim of the study is to assess the impact of chlorhexidine mouthwash performed before surgery on the bacterial colonization of the pharyngeal mucosa.
Verify the effect and the incidence of oral mucositis of concurrent chemoradiotherapy in locally advanced squamous cell carcinoma of the head and neck versus concomitant cetuximab with radiotherapy after neoadjuvant chemotherapy. The predictive effect of Apurinic/apyrimidinic endonuclease 1(APE1)/ Ref-1 protein and Apurinic/apyrimidinic endonuclease 1(APE1)/Ref-1 antibody on oral mucositis.
Primary objectives: 1. 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. 2. 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. 3. 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.
Up to 90% of the radiotherapy patients will develop a certain degree of skin reaction at the treated area, also known as radiodermatitis (RD). Currently, there is a wide variety of strategies to manage RD, including creams, gels, ointments, wound dressings. However, up to now, there is still no comprehensive, evidence-based consensus for the treatment of RD. Low-level laser therapy (LLLT) is a promising, non-invasive technique for treating RD. In a recent study conducted in our research group, LLLT prevented the aggravation of RD and provided symptomatic relief in patients undergoing radiotherapy for breast cancer after breast-sparing surgery. This was the first prospective study investigating the potential of LLLT for RD. In the current study, we want to investigate the efficacy of LLLT as a tool for the prevention of radiodermatitis in head and neck cancer patients.
To investigate the incidence of tuba dysfunction (TD) and middle ear (ME) morbidity after radiotherapy (RT) to the Head & Neck and test the effect of auto-inflation of the Eustachian tube (ET) on middle ear effusion with a special designed balloon (Otovent®) and thereby better hearing and ear related quality of life after cancer treatment.
Squamous cell carcinoma (HNSCC) is the most frequent form of head and neck cancer. The therapeutic choice depends on the stage of the disease and the habits of the medical teams. Surgery, radiotherapy and chemotherapy can be used, alone or combined. However, none of the existing strategies has proven its superiority. Chemotherapy and radiotherapy induce DNA damages in the tumor cells. However, cells have the ability to induce DNA reparation, capable of causing treatment resistance. DNA reparation in non-tumor tissues can also explain the toxicity of cancer treatments. Investigation of DNA repair pathways involved in chemo- or radiation resistance could offer a good strategy for identifying biomarkers or indicators of treatment response. This study will explore the capacity of a comprehensive functional approach that addresses several pathways, based on the use of three innovative patented technologies, to classify the tumor response of HNSCC patients to treatments according to their DNA Repair Enzyme Signature. Our hypothesis is that taking into account various clinical parameters (e.g. patient and tumor characteristics), treatment strategy and measuring the DNA Repair Enzyme Signature would create patients' profiles and optimize their management.
The primary objective of the study is to characterize the medical management of squamous cell carcinoma head and neck (SCCHN) patients diagnosed with recurrent/metastatic (R/M) disease (between 01July2013 and 30 June 2014) in the real-world setting.
The last decade has seen progressive advances in RT delivery, such as intensity modulated radiation therapy (IMRT)and image-guided radiation therapy (IGRT), which now allow highly precise radiation dose delivery. Together, IMRT and IGRT offer the potential of more selective treatment of the primary tumour and surrounding neck nodes by reducing the dose inflicted on critical organs at risk without compromising tumour dose and. IMRT has been shown to significantly decrease radiation-induced toxicity, and is now considered standard treatment for H&N tumors. With these advances in delivery technology, the accurate definition of the target is emerging as the weakest link in the radiotherapeutic treatment chain. Accurate target definition is the primary link on which all subsequent treatment planning and delivery depend and is therefore critical for successful RT. Incorrect target definition can result in poorer outcomes through either less tumour control, more normal tissue toxicity, or both. Computed x-ray tomography (CT) is the standard volumetric imaging modality for RT because of its high resolution, accurate definition of anatomy and its intrinsic measure of electron density necessary for accurate dose calculation. However, its ability to distinguish between tumour and normal tissue is limited due to a lack of contrast for structures of similar electron density and image artifacts for objects of high density. This additional noise can result in large inter-observation variability. Disease visible on endoscopy can be contoured and registered to the planning CT, allowing inclusion of superficial disease invisible on the volumetric CT image dataset into the treatment plan.
