The objective of this protocol is to develop an institution-wide liquid biopsy protocol that will establish a common process for collecting blood and corresponding archived tumor specimens for future research studies at the University Health Network's Princess Margaret Cancer Centre. Circulating cell-free nucleic acids (cfNA), including cell-free DNA (cfDNA) and cell-free RNA (cfRNA), are non-invasive, real-time biomarkers that can provide diagnostic and prognostic information before cancer diagnosis, during cancer treatment, and at disease progression. Cancer research scientists and clinicians at the Princess Margaret are interested in incorporating the collection of peripheral blood samples ("liquid biopsies") into research protocols as a means of non-invasively assessing tumor progression and response to treatment at multiple time points during a patient's course of disease.
The present study is to evaluate the effect of anesthetic agents ( propofol , sevoflurane) on intracranial pressure of female patients undergoing laparoscopic-robotic surgery.
Programmed cell death 1 (PD-1) inhibitor treatment may benefit patients with endometrial cancer (EC) based on the following observations: 1) an overwhelming presence of PD-1 in ECs; 2) the well-known effect of obesity which activates pro-inflammatory white blood cells and promotes the development of ECs; and 3) the high prevalence of a specific gene pattern (ie, microsatellite instability hypermutated [MSI high]) among ECs that may be particularly sensitive to this class of drugs. To identify potential biomarkers of response to PD-1 inhibitors in EC, we will conduct a window of opportunity study of pembrolizumab in 20 patients with clinical stage 1, grade 3 EC, encompassing endometrioid, serous and clear cell histologies. Eligible patients will undergo a research biopsy for collection of fresh tissue at the time of enrollment, in addition to the routinely performed endometrial biopsy that led to the diagnosis of their cancer. Patients will receive a single dose of pembrolizumab (200 mg IV) prior to undergoing their scheduled hysterectomy with surgical staging three weeks later. As per standard of care, adjuvant chemotherapy with paclitaxel and carboplatin will be recommended after hysterectomy/surgical staging for women with endometrioid tumors and stage III disease or women with serous/clear cell tumors at all stages of disease. However, in this study pembrolizumab will be added to adjuvant paclitaxel and carboplatin for EC. Pre-treatment endometrial biopsy specimens (fresh frozen tissue and formalin-fixed paraffin embedded (FFPE)) and a post-treatment hysterectomy specimen (fresh frozen tissue and FFPE) will be collected for translational studies. Blood, fecal and vaginal samples will be collected pre-treatment, at the time of surgery and following 3 cycles of adjuvant pembrolizumab/paclitaxel/carboplatin treatment.
This trial studies how well two different supportive programs work in supporting optimal recovery in participants undergoing gynecological surgery. Supportive programs use different methods for helping participants cope with the surgical experience including gentle movements, counseling, writing, or relaxation techniques, and may help improve participants' well-being after gynecological surgery.
This research study is studying an investigational drug as a possible treatment for uterine cancer. The drug involved in this study is: -AZD1775
The primary objective of this study is to obtain de-identified, clinically characterized, whole blood specimens to evaluate biomarkers associated with cancer for diagnostic assay development.
This randomized phase II trial studies how well olaparib, cediranib maleate, and Wee1 inhibitor AZD1775 work in treating patients with endometrial cancer that has come back, does not respond to treatment, or has spread to other places in the body. Olaparib, cediranib maleate, and Wee1 inhibitor AZD1775 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
The purpose of this study is to determine the effectiveness of the combination of abemaciclib and fulvestrant in treating this type of cancer and to determine the types and severity of side effects caused by treatment with abemaciclib and fulvestrant.
Evaluation of clinical, therapeutic and prognostic relevance of new experimental results as well as optimization of therapeutic models and development of a new algorithm for therapeutic plan and therapy in patients with uterine neoplasm
Patients with primary peritoneal cancer or secondary peritoneal cancers from stomach, colorectal, appendiceal, and gynecological primary origin will be screened by pathology and staging to see if they are eligible to undergo cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC). To be eligible for the study, patients must be over 18 years of age, have appropriate pathology and stage with disease confined to the peritoneal cavity, have a good performance status, have laboratory values that fall within safe ranges to undergo an operation and receive intraperitoneal chemotherapy. The chemotherapeutic agent and dose will be assigned based on pathological diagnosis in accordance with current standard of care. Surgery will be performed with the goal of removing all visible tumor that may require removal of adjacent organs. Once only microscopic disease is present, the chemotherapy will be delivered directly into the peritoneum via intraperitoneal hyperthermia and perfusion device. This will continue for 90 minutes. Patients will be followed for tumor response, survival, toxicity, complications, quality of life, and tumor markers. They will have regular follow up visits with the surgeon, undergo routine surveillance imagings, and receive follow up phone calls periodically.
