Filter by:This is an observational study with the goal to improve the robustness of the scientific evidence linking Fusobacterium nucleatum (Fn) and/or other microorganisms to colorectal cancer (CRC) onset and/or progression. This is an approximately three-year study. There are two phases to this study, including: 1) pilot phase, 2) full study. There are also five arms in this study including cancer-free, pre-cancerous, and Colorectal cancer stages (I-III). The pilot study will include the recruitment of 50 participants per group (i.e., total of 250 participants). The full study will have an additional 150 participants per group (total of 1,000 participants). This study will recruit using clinical sites in the United States. There are 5 timepoints in this study. If the participants are found to be medically eligible through diagnosis and medical information, they will provide samples (including: saliva, blood, urine, stool and tumor biopsy) at each timepoint and during the study. They will also answer health and wellness questions during this study. Additional data collection, including medical data, biopsies and other biological samples might happen at interim timepoints in case of adenoma/cancer disease progression (recurrence, metastasis). The participant's healthcare provider will determine if additional biopsies are required as a part of the standard of care. If collected, additional samples will be sent for research purposes.
A study evaluating the drug levels of ipilimumab alone and in combination with nivolumab applied under the skin in various tumor types
This study is a dose escalation, and cohort expansion study in subjects with advanced cancer for which no standard therapy exists. Subjects must have received prior treatment for cancer that has not worked, or has stopped working.
Elderly cancer patients need more help from their relatives and for longer than young adults. Our hypothesis of research is that the needs and resources to help the couple " elderly patient/caregiver ", are at least in part socially determined and that the implementation of a personalized support plan to help the caregiver (PSP) taking into account needs, resources and expectations of the primary caregiver in addition to those of elderly patients with cancer may partly correct inequalities. The PSP should allow a better management of cancer, a lesser burden for the caregiver and a better quality of life for both the caregiver and the patient.
The purpose of this study is to: - Determine how well people tolerate sodium bicarbonate taken by mouth in higher doses than those usually given for heartburn. - Determine if sodium bicarbonate can reduce cancer-related pain.
ROLE OF SUCTION IN EUS-FNA: Current suction technique involves suctioning the aspirate into the needle that has an air column. The needle is not flushed with any liquid prior to passing into the desired solid lesion. Suction is applied when the needle is within the lesion leading to aspiration of tissue into the needle. This is the standard technique and some have done with and without the stylet. There are some data that favor non use of a stylet. WET SCTION TECHNIQUE: Wet suction technique involves flushing the needle with 1-2 cc of saline to replace the column of air with saline. The needle is now passed into the desired lesion. Suction is applied at maximal strength and needle moved back and forth within the lesion to obtain as aspirate. Drops of saline can be seen moving into the suction syringe as the aspirate moves into the needle. Needle is now withdrawn and aspirate delivered on to a slide by using a stylet and or flushing air into the needle with a syringe. HYPOTHESIS The effect of suction for the purpose of aspirating cells and / or tissue during fine needle biopsy may be significantly improved by filling the column of the needle with a less compressible fluid. The volume of vacuum being pulled may be negatively impacted by the expansion of air within the needle. Replacing the air with sterile saline may thus improve the suction transferred to the needle tip by ensuring that the full volume of the vacuum syringe is transferred to the distal tip of the needle. This effect would be most pronounced in larger gauge needles which would have a larger internal volume. An additional benefit of filling the needle with saline prior to aspiration is the speed of the pressure transfer. The theory is that the air in the needle may absorb some of the force of the sudden application of vacuum. A column of saline in the needle may increase the velocity of the pressure transfer providing more tissue and less blood.
The purpose of this study is to determine whether aprepitant can be used in the Cisplatin - Etoposide chemotherapeutic regimen.
AV-412 is a new oral therapy developed to inhibit the growth of solid tumors in patients who have not responded to standard therapy or surgical interventions, or who have experienced relapse. This study will test the safety of AV-412 and determine the maximum tolerated dose for the treatment of solid tumors.
