Active clinical trials for "Carcinoma, Squamous Cell"

Anatomical changes that take place during Intensity modulated radiation therapy (IMRT) treatments for cancers of the head and neck cause significant dosimetric changes.

Correlation between serum squamous cell carcinoma antigen level and tumor volume in Head and Neck Cancer is to determine a correlation between level of serum squamous cell carcinoma antigen and tumor volume in Head and Neck Caner measured by cross-sectional imaging.

The primary objective is to collect emission spectra of normal tissue, pigmented normal lesion, benign lesion, SCC, BCC and melanoma to construct the database and validate the classifying algorithm.

This is a minimal risk feasibility study involving the analysis of patient samples and does not involve any therapeutic intervention. The study will involve a prospective cohort of up to 60 patients diagnosed with Locoregionally-Advanced Oropharyngeal Squamous Cell Carcinoma (LA-OPSCC) treated with chemoradiotherapy (CRT) at Princess Margaret Cancer Centre.

The purpose of the study is to capture the utilization of nivolumab among participants with squamous cell carcinoma of the head and neck (SCCHN) since its approval, and to describe the health related quality of life (HRQoL) among participants treated with nivolumab in a real-world setting.

Background: Pilonidal sinus is a very common disease. Malignant transformation occurs in 0,1% of patients. The investigators present a case of squamous cell carcinoma arised from recurrent pilonidal disease, managed by multimodal treatment. Case presentation: The investigators present a 70-year-old man with chronic pilonidal sinus. Inflammation had worsened in previous months and exploration revealed a large ulcerative mass which biopsy showed a squamous cell carcinoma. CT scan and MRI imaging showed tumoral invasion of the coccyx and both gluteus major muscles. Neoadjuvant radiotherapy, chemotherapy as radiosensitizer and surgery with intraoperative radiotherapy was decided in the multidisciplinary tumor committee. Post neoadjuvant therapy MRI showed partial response with a decrease of the mass but persistence of the coccyx infiltration. Surgery consisted in en-bloc resection of the tumor with presacral tissues, coccyx and partial gluteal resection. Intraoperative radiotherapy was administered over the sacrum and in the bed of the coccyx resection. One week later, reconstructive surgery was practiced using a latissimus dorsi free flap, advancement of gluteal flaps and skin graft. Histological examination showed no residual tumor. The patient is currently asymptomatic and he has a satisfactory quality of life. Conclusions: Although squamous cell carcinoma is rare, it must be suspected in patients with recurrent pilonidal disease. Diagnosis is done by histological examination of biopsies. This type of tumors have a high local recurrence rate. The investigators propose a multimodal treatment that includes neoadjuvant radiotherapy and chemotherapy as radiosensitizer and surgery plus intraoperative radiotherapy with the aim to decrease local recurrence rate.

MicroRNAs (miRNAs) are a novel class of short RNAs which have shown to be dysregulated in a variety of cancers. Data of miRNA expression in cutaneous squamous cell carcinoma (cSCC) is very limited and microarray based genome wide miRNA expression profiles of cSCC have not been investigated so far.

Previous studies indicate that there are significant differences in the temperature of tumors and normal, adjacent tissues. The present study will test this hypothesis for lesions in the oral cavity. Thermal images of the oral cavities of patients, undergoing examination in the Department of Oral and Maxillofacial Surgery of Sheba hospital, will be compared to the diagnoses of the examining doctors. The results, apart from enhancing the delineation of oral cavity tumors, may help the decision to develop miniature thermal cameras to scan thermally, the GI tract.

Patients with squamous cell cancer of neck nodes but unknown primary will have a PET-CT scan prior to biopsies. The utility of PET-CT will be determined in this subset of patients.

The purpose of this study is to finalize development of a questionnaire that measures health-related symptoms and concerns for persons diagnosed with, and either treated or monitored for, anal pre-cancer lesions.
