The purpose of this research study is to determine the rate of local regional control at 2 years when using de-intensified chemoradiotherapy (CRT) in patients with Human Papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC). Local regional control means no recurrence of the cancer in the head or neck area. Study subjects will be enrolled into 4 groups. Group/treatment will be based on a number of factors, including smoking and drinking history.
The primary objective of this study is to evaluate the humoral immune response to CVnCoV in elderly adults aged ≥65 years and younger adults aged 18-45 years, 14 days after the second dose administration.
This phase Ib/II trial studies the side effects of acalabrutinib and duvelisib and how well they work in treating patients with indolent non-Hodgkin lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Acalabrutinib inhibits a signaling molecule called Bruton tyrosine kinase and blocks cancer cell proliferation, growth, and survival. Duvelisib is designed to block a protein called PI3 kinase in order to stop cancer growth and cause changes in the immune system that may allow the immune system to better act against cancer cells. Giving acalabrutinib and duvelisib together may work better to block cancer growth than therapy of either drug alone.
This phase II trial studies the effect of re-irradiation with NBTXR3 in combination with pembrolizumab in treating patients with head and neck squamous cell cancer that cannot be removed by surgery (inoperable) and has come back (recurrent). NBTXR3 is a drug that is designed to improve the effectiveness (how well something works) of radiation therapy. The drug is injected into a tumor and activated (turned on) by radiation. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Radiation therapy, such as intensity modulated radiation therapy or intensity modulated proton therapy, uses high energy to kill tumor cells and shrink tumors. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving NBTXR3 activated by radiation together with pembrolizumab may help to control head and neck squamous cell cancer.
Postoperative antibiotics are routinely used for implant-based breast augmentation at the investigators' institution. From 2017-2019, the investigators' institution has conducted approximately 270 primary and secondary breast augmentation procedures. Current plastic surgery literature does not provide recommendations for antibiotic prophylaxis following implant-based breast procedures. Despite controversy surrounding their utility during the postoperative course, postoperative antibiotics have become commonplace for many plastic surgeons. To date, strong scientific evidence supporting this practice is minimal and based largely on anecdotal evidence and limited studies, including poorly controlled retrospective and non-blinded prospective series. The goal of this study is to conduct a prospective randomized trial to assess whether extended antibiotic prophylaxis is necessary to prevent infection and long-term complications (e.g. capsular contracture) in patients undergoing augmentation mammoplasty with implants. The investigators' anticipate that extended antibiotic prophylaxis is not required. The rationale for discontinuing postoperative antibiotics is based on the following: (1) a single dose of preoperative intravenous antibiotics has been demonstrated to be sufficient prophylaxis for most breast surgeries and (2) there are patient safety concerns associated with prolonged antimicrobial use such as the development of resistant bacterial strains and clostridium-related infections. Concrete evidence that extended antibiotic prophylaxis is not required would encourage plastic surgeons to practice better antibiotic stewardship and help stymie the rise of drug-resistant organisms.
This is a randomized trial to assess the efficacy of reminder mechanisms on colorectal cancer (CRC) screening uptake among a cohort of patients who were previously mailed a multitarget stool DNA (mt-sDNA) test and did not complete the screening. Patients will be identified as being due for CRC screening and will be mailed a mt-sDNA kit to their home. Patients who do not complete screening with mt-sDNA within 30 days will be identified and randomized into one of three study arms to receive reminders to complete the mt-sDNA screening. The primary outcome is the rate of completion of screening for colorectal cancer with mt-sDNA test.
The purpose of this study is to evaluate the experimental immunotherapy agent cemiplimab-rwlc when given after completion of chemotherapy and radiation treatment and determine if it will improve progression free survival and cure rates in patients with PD-L1 positive locally advanced head and neck cancer.
Although the notions that kidney transplantation is the treatment of choice for patients with end-stage renal disease and that simultaneous kidney and pancreas transplant is the only treatment able to restore euglycemia in patients with type 1 diabetes and selected patients with type 2 diabetes, are now consolidated, rates of transplantation remain low among potential candidates with high levels of preformed anti-HLA antibodies. Most of the data comes from the experience in kidney transplant but can be easily translated to pancreas transplant. Approximately 30% of patients on the transplant waiting list have evidence of sensitization in the form of alloantibodies, generated from exposure to previous transplants, blood transfusions, pregnancy, or other events. The presence of a panel-reactive antibody level of at least 80% (i.e. a high level of sensitization) creates difficulty in finding matched kidneys from compatible donors, leading to lower rates of transplantation in highly sensitized candidates compared to non-sensitized; the longer waiting times translates in an increased mortality rate. Despite the development of desensitization strategies and the advancement in immunosuppression protocols, it is apparent that transplanting these patients carries an increased risk of acute antibody mediated rejection; 25%-50% of transplants will have an early acute antibody mediated rejection . Most of these rejections can be successfully treated, but a high rate of transplant glomerulopathy and chronic antibody mediated rejection (AMR) leading to accelerated allograft failure is common.
After well-conducted treatment of ovarian, tubal and primary peritoneum cancer by maximum tumor reduction surgery and chemotherapy including platinum salt and paclitaxel, the clinical remission rate is over 50%. However, 75-80% of patients with ovarian, tube or primary peritoneum cancer recur within 2 years of the end of treatment. In the latest INCa recommendations for 2018, systematic imaging (thoraco-abdomino-pelvic scanner (CT), MRI, PET CT) is not recommended based on the literature because of its low added value compared to CA 125 dosage (sensitivity ranging from 67% to 95%, and specificity of 87% to 93%), its irradiating character (CT) and its cost. However, the recommendations are based on imaging studies dating back at least a decade. Since these studies, technological advances have improved the diagnostic performance of imaging: sensitivity is 78% for whole-body CT scans and 98% for full-body MRI for the diagnosis of ovarian cancer recurrence. Furthermore, previous randomized studies showed no survival benefit with early treatment of relapse on the basis of a high concentration of CA125 alone, so the value of routine CA125 measurement in the follow-up of ovarian cancer patients may be limited. These recent studies lead to heterogeneity in surveillance protocols for ovarian cancer patients despite recommendations. In addition, treatments for recurrences have evolved as well as maintenance treatments to become chronic treatments, with the emergence of the maintenance new treatments detecting early recurrence is particularly important (notably through the development of new molecules given in maintenance treatment). But early detection have to be balanced with the quality of life of these patients. In usual care, imaging surveillance is often carried out despite the absence of recommendations or data from the literature of high level of evidence. The question arises as to whether radiological monitoring could make an impact on patient survival without being a source of excessive false positives, patient stress and non-productive costs. QUALOV trial is a multicenter randomized study for patients in remission after treatment of advanced stage serous epithelial ovarian, fallopian tube or primary peritoneum cancer (stage III and beyond). The main objective is to assess the effectiveness of systematic imaging for patients followed after advanced stage serous epithelial ovarian, fallopian tube or primary peritoneum cancer
