Filter by:Background: A cancer treatment has been developed called "gene transfer" or "gene therapy." It involves taking white blood cells from a person (called apheresis), genetically modifying the cells in a lab to recognize cancer, and then giving the cells back to the person. Researchers want to see if this treatment can help people with metastatic squamous cell anal cancer. Objective: To see if treating cancer with a person s own white blood cells that have been genetically modified can cause tumors to shrink. Eligibility: People who have metastatic squamous cell anal cancer for which standard treatments have not worked. Design: Participants will have had a tumor biopsy and apheresis to collect white blood cells under a separate protocol. Participants will stay at the hospital for 3 to 4 weeks. They will have an intravenous (IV) catheter placed in a large vein in the upper chest. Participants will get chemotherapy drugs (fludarabine and cyclophosphamide), the cell infusion, and aldesleukin through the IV. Pembrolizumab is given before and for three doses given every three weeks after the cell infusion. Aldesleukin will help the cells grow. Participants will take an antibiotic, antiviral, and antifungal by mouth. They will get an injection of filgrastim. It will stimulate the formation of white blood cells. Participants will have blood and urine tests. They will have physical exams. Their symptoms will be reviewed. They will have imaging scans. About 6 and 12 weeks after they finish treatment, participants will have safety follow-up visits. These visits will take 1 to 2 days. Participants will return to the Clinical Center every 3 to 6 months for 3 years, and then as determined by their doctor. They will be followed long term for up to 15 years on a separate study.
Even if squamous cell carcinoma of the anal canal (SCCA) is a rare disease, its incidence increases worldwide. SCCA is mostly induced by Human papillomavirus (HPV) infections and HPV-related oncoproteins (E6 and E7) are expressed in more than 90% of SCCA. T stage and N stage are recognized prognostic factors for local and/or distant recurrence in SCCA patients treated by chemoradiotherapy. In fact, ≥T3 or ≥N1 anal cancers are associated with as high as 50% of disease recurrence rate at 2 years. The University Hospital of Besançon with the Gercor conducted a prospective clinical trial (Epitopes HPV02 study) including 69 advanced SCCA patients and established a new standard of care based on Docetaxel, Cisplatin and 5-FU (5-FluoroUracil) chemotherapy (DCF). Among 69 patients treated with DCF regimen, 66 patients were evaluable for efficacy end-points. The objective response rate was 86% including 44% of complete response, and 47% of patients were progression-free at 12 months of follow-up from the first cycle of DCF treatment. Thus, the "Epitopes-HPV02" trial has demonstrated a high response rate of the DCF regimen with a higher than expected 12 months progression-free survival rate.These results raised the hypothesis of DCF being an immunogenic chemotherapy and in that demonstrating a possibly new role of taxane-based chemotherapy in SCCA patients. More than 50% of patients in complete remission had a detectable immunological response against peptides derived from HPV oncoproteins (E6 or E7) or from the telomerase antigen (which is transactivated by E6). LAND study will enroll patients with locally advanced SCCA enrolled in OPTIMANAL clinical trial. OPTIMANAL study will assess the feasibility and efficacy to combine nivolumab to mDCF chemotherapy, followed by the standard chemo-radiotherapy, in high risk locally advanced SCCA patients with T3/T4 N1a or N1b/N1c disease. LAND study is an exploratory translational study, which will analyze the biological mechanisms of action and our ability to track the immune responses against HPV and telomerase. The investigator group will take advantage of the presence of HPV antigens in most patients to set up a specific immunomonitoring program based on tumor samples and blood-derived lymphocytes to better understand the potential synergisms between immunogenic chemotherapy and anti-PD1 (Programmed Death-1), and to identify valuable biomarkers of treatment efficacy.
Prospective, open-label, within-subject, multi-center pilot study of Lymphoseek in the detection of lymph nodes in subjects with known squamous cell carcinoma of the anus.
The purpose of this study is assess the technical and operational feasibility of a specialised biopsy technique, sentinel lymph node biopsy (SLNB), in patients with anal cancer.
The purpose of this study is to establish a prospective database of anal canal and perianal cancer patients treated with IMRT and chemotherapy with curative intent at PMH for the purposes of investigating MRI-derived primary tumor parameters. Patients who decide to participate in this study will be treated according to standard treatment policies and radiation therapy planning protocols at Princess Margaret Hospital (PMH) with radiation therapy +/- chemotherapy. IMRT for all treatment phases of radiotherapy has been implemented as standard treatment. Surgery is reserved for salvage treatment.
We have an active research program in gastrointestinal cancers including clinical trials, epidemiologic, and translational studies. We would like to establish a biospecimen bank linked to useful clinical information in order to learn more about diagnostic, predictive and prognostic markers for gastrointestinal cancers. PRIMARY OBJECTIVES: 1. To collect and store tumor and normal tissue (previously collected paraffin embedded or frozen specimen) and blood in patients with gastrointestinal (GI) cancers. SECONDARY OBJECTIVES: 1. Collect detailed clinical information via a patient questionnaire that includes demographic, socioeconomic, lifestyle, family, past medical, medication and cancer histories 2. Collect details about the tumor specimen extracted from patient charts.
