Active clinical trials for "Carcinoma, Squamous Cell"

Data were collected on a large multi-institution dataset consisting of ESCC patients who underwent surgery between January 2003 and December 2013 at ten institutions in the People's Republic of China. The datasets were approved for research by the institutional review board of each participating center. Prior to surgery, all patients received computerised tomography (CT) of the chest and abdomen and EUS as part of their routine staging workup. Patients received whole body FDG-PET to eliminate the possibility of distant metastases if the attending physician considered it was necessary. All patients in the dataset received a surgical R0 resection; patients who received an R1 or R2 resection were excluded. Notably, there is nothing approaching a consensus on the extent of lymph node dissection for ESCC patients. Patients who received neoadjuvant therapy were excluded due to the influence of neoadjuvant therapy on lymph node status and pathologic T stage. The primary endpoints were overall survival (OS), which was defined as the time between surgical resection and death from any cause, and cancer-specific survival (CSS), defined as the time from surgical resection to death caused by ESCC. After receiving esophagectomy, patients were followed up by clinical examination every three months for the first year, every three to six months for the second year, and every six to twelve months from then on.

This study aims to study the kinetics of ctDNA levels after the first dose of immune checkpoint inhibitor in patients with recurrent or metastatic head and neck cancer. This is an important study to understand the optimal timing for ctDNA quantitation for future studies in immunotherapy, though further validation would be needed in other tumor types. It may help standardize the most relevant blood collection time points so that patients will not be subjected to multiple blood draws at random time points in future liquid biopsy trials.

This study is a retrospective real-world study. In this study, we plan to collect the clinical data of LASCCHN patients who received chemoradiotherapy combined with or without nimotuzumab .

Head and neck cancer (HNC) continues to be a significant health care problem in Taiwan and oropharyngeal squamous cell carcinoma (SCC) is the common subtype. With the concern of organ preservation in recent years, concurrent chemoradiation is the major treatment modality for oropharyngeal SCC, while endoscopy with biopsy serves as the main diagnostic tools. With the advance of MRI technology, whole body MRI is now possible, and functional techniques become more feasible in the head and neck region, including diffusion-weighted imaging (DWI) which comprises of monoexponential DWI, intravoxel incoherent motion (IVIM) model and Kurtosis (biexponential or non-Gaussian fitting), and dynamic contrast-enhanced perfusion weighted MRI (DCE-PWI) become feasible. Therefore, MRI can evaluate distant site status of HNC in the single examination session and provide biologic information of tumors. Positron emission tomography/CT (PET/CT) is another common imaging modality to evaluate HNC, because of its ability to provide whole-body anatomic and metabolic information. Integrated PET/MRI is a novel imaging technology that combines PET and MRI in one single scanner. In this 3-year prospective study, the investigators will take the advantages of integrated PET/MRI scanner with DWI (including monoexponential, kurtosis and IVIM modes) and DCE-PWI to evaluate our 160 patients with oropharyngeal SCC subjected to chemoradiation. Non-contrast chest CT will also be performed on the same day. The investigators aim to determine whole-body staging/restaging accurately, to predict treatment response and prognosis, and to determine necessity of noncontrast chest CT. The investigators expect that this project will offer the validation of usefulness of integrated PET/MRI in tumor staging/restaging of oropharyngeal SCC and resultant clinical impact. The role of noncontrast chest CT in the workup with our PET/MRI protocol can be defined. It will also provide evidence about how and to what extent the various simultaneously acquired MRI and PET functional parameters can help prediction of treatment response and prognosis of oropharyngeal SCC subjected to chemoradiation, which are important in timely modification of treatment regimen.

This study was designed to verify the role of salivary LINC00657 as a diagnostic marker in oral squamous cell carcinoma (OSCC) patients as compared to oral lichen planus (OLP) (as an example of oral potentially malignant lesions) and normal individuals, and to show its relation to miR-106a. A total of 36 participants were included.

The primary objective is to describe the real-world clinical effectiveness of cemiplimab in patients with locally advanced cutaneous squamous cell carcinoma (laCSCC) or metastatic cutaneous squamous cell carcinoma (mCSCC) treated in routine clinical practice.

This is a prospective, observational, non-interventional, multicenter, post-marketing surveillance study to mainly collect safety information from subjects with locally advanced and recurrent/metastatic Squamous Cell Carcinoma of Head and Neck (SCCHN) treated with cetuximab based on the locally approved label.

Esophageal squamous cell carcinoma is considerably more prevalent in East Asia. Despite of relatively high prevalence of esophageal SCC, prognosis is very poor with limited options of effective chemotherapy regimens. We attempted to identify favorable subgroups of patient who are likely to benefit from 5- fluorouracil/cisplatin(FP) or capecitabine/cisplatin (XP) chemotherapy as first-line treatment.Between January 2000 to December 2010, 239 patients were diagnosed of recurrent, metastatic esophageal SCC and received either FP or XP as first-line chemotherapy. Clinicopathologic variables and treatment outcome were retrospectively collected. we analysis treatment outcome of palliative chemotherapy in metastatic esophageal squamous cell carcinoma and make prognostic scoring system. The present study represents the largest series to analyze the treatment outcome of FP/XP chemotherapy in metastatic SCC. Risk-adapted stratification of treatment for subgroup of metastatic SCC patients should be actively pursued.

This clinical trial studies glycoprotein and glycan in tissue and blood samples of patients with stage IB-IVA cervical cancer undergoing surgery to remove pelvic and abdominal lymph nodes. Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer. It may also help doctors learn how far the disease has spread.

The purpose of this study is to determine whether afamelanotide (CUV1647) is effective in reducing the number of actinic keratoses and squamous cell carcinomas developing in immune compromised organ transplant recipients, who are at particularly high risk, over a 24 month test period. The number of lesions formed on the head, hands and forarms will be monitored over this 24 month test period.
