Active clinical trials for "Carcinoma"

In this international collaboration study, the research group will analyze somatic mutations of hepatocellular carcinoma (HCC) developed after sustained virological response (SVR) in patients treated with hepatitis C (HCV) therapy

To compare Child-Pugh and Albumin-Bilirubin scores in patients with spontaneous rupture of hepatocellular carcinoma

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.

Correlation analysis between estimated renal function and biological half life of 131-I during radioiodine treatment of patients with differentiated thyroid cancer.

The study would examine by hypericin-supported Fluoreszenzlaparoskopy in terms of tumor size, number and location of the combination of photodynamic diagnosis (PDD) and therapy (PDT) with regard to the detection of peritoneal metastases of locally advanced gastric cancer at 50 adult patients.

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.

Non-muscle invasive bladder tumor is a condition that can recur with a risk of progression to an infiltrating tumor of the muscle. Regular follow-up is therefore essential to detect any recurrence or progression of the disease as early as possible. Currently, the monitoring of this type of tumor is done by cystoscopy (examination that allows visualization of the bladder wall) associated with urinary cytology (analysis of urine to detect an abnormality). These examinations have their limits, they may not detect certain types of tumors or may be painful. To reduce the number of cystoscopies and replace urinary cytology, several urinary markers have been developed in recent years. This is the case of the Xpert® Bladder Cancer Monitor test, which is a non-invasive, in vitro diagnostic urine test dedicated to the monitoring of patients with bladder cancer. The purpose of this study is to evaluate the diagnostic performance of the Xpert® Bladder Cancer Monitor test for the detection of bladder tumor recurrence, compared to reference tests.

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.

In the last decade, investigators from the Department of Cancer Epidemiology and Genetics (National Cancer Institute, USA) have conducted genome-wide association (GWAS) studies of renal cell carcinoma. Dr. Mark PURDUE and Dr. Stephen CAHNOCK (Department of Epidemiology of Cancer and Genetics, NCI) propose to expand their genome-wide association study (Expanded GWAS) by genotyping approximately 10,000 additional cases of kidney cancer patients, in collaboration with US institutions, South-American and European. This study describes the participation of the French Kidney Cancer Research Network (UroCCR) in the Expanded GWAS research, under the coordination of Professor BERNHARD (Bordeaux University Hospital).
