Perioperative Immunonutrition Under Enhanced Recovery After Surgery

The goal of this clinical trial is to compare the effect of perioperative immunonutrition supplement in gynecologic cancer patients. The main questions it aims to answer are: * is there any difference in the nutritional outcomes and functional outcomes between intervention and conventional groups? * is there any difference in the post-surgical outcomes between intervention and conventional groups? Participants (intervention) will be provided the immunonutrition supplement before and after operation. Researchers will compare intervention group with conventional group to see if there is any difference in postoperative outcomes.

Evaluate the Effectiveness of the Mobile Instant Messaging Intervention

This study explores the caregiving needs of male spouses and develops an instant messaging software intervention to provide effective support. The goal is to help male spouses better adjust to their caregiving roles, reduce psychological stress and emotional distress, and improve overall health. A randomized controlled trial will be conducted to evaluate the effectiveness of the mobile instant messaging intervention, analyzing its impact on reducing psychological distress and improving the quality of life of male spouses.

Genomic Investigation of Unusual Responders

Studies have shown that tumors from the same patient may respond very differently to the same therapeutic agents. This study aims to investigate the genetic basis of tumors that respond abnormally well or poorly to therapeutic agents in an effort to understand the fundamental genetic basis of this response. The present protocol seeks to retrospectively perform Exome, next-generation (DNA) sequencing and/or other molecular techniques on tumor samples to identify the genetic basis of a patient's exceptional response to chemotherapy.

Detection of Circulating Therapeutic Monoclonal Antibodies in Biological Samples of Gynecological Cancer Patients.

Quantification of anti PD-1 mAbs in cancer patients is extremely important to monitor pharmacokinetics and effectiveness of immunotherapy. To detect the ICI mAbs in patients' blood plasma samples, we select three anti PD-1 mAbs (cemiplimab, dostarlimab and pembrolizumab) as prognostic biomarkers which will be quantified using different biochemical/analytical assays.

Laparoscopic Surgical Systems for Gynecological and Remote Surgical Treatment.

Remote robot-assisted laparoscopic surgery will be performed for gynecological surgical treatment through 5G network, while the safety and effectiveness will be studied.

Supplemental High Flow Oxygen to Reduce Infections in Obese Gynecological Cancer Patients

The incidence of surgical-site infection (SSI) and complications related to wound healing reaches 10-20% of gynecological cancer patients. Each complication may dramatically prolong the hospitalization period and increase the economic burden of hospital care. Appropriate wound care and tissue oxygenation are of special importance for wound healing. Assuming adequate perfusion, the easiest, safest, and most effective way to improve tissue oxygenation is to increase the fraction of inspired oxygen. However, there is considerable controversy as to whether supplemental oxygen actually reduces SSI and healing-related complications as to date, there is absence of relevant data.

Breathing Exercise Application in Patients With Gynecological Cancer.

The aim of this study is to determine the effects of breathing exercises on nausea, vomiting and anxiety levels in patients with gynecological cancer.

Ontario-wide Cancer TArgeted Nucleic Acid Evaluation

Substantial progress has been made in the treatment of cancer through the use of targeted therapies, but what works for one patient might not work for another patient. Certain drugs are now being developed that target specific molecules in the body that are believed to be part of the disease. Biomarkers are specific characteristics of the cancer that may help provide prognostic information (e.g. how well patients will be regardless of the treatments given) or help predict sensitivity or resistance to a specific treatment. The study will collect archival tumor samples (previously collected biopsy or surgical tumor samples) to provide biomarker data about a patient's cancer, which may help their physicians to identify which clinical trials of new drug treatments may be most appropriate for the patient in the future and may also guide the use of approved treatments that may potentially benefit the patient. Another goal of this study is to develop a province-wide registry of targeted gene sequencing testing results that will be made available to cancer researchers. Additional tumour tissue and blood samples collected from all study participants will also be stored in a biobank at the Ontario Institute for Cancer Research for future research. The study will also look at linking data from this study to other health care databases to further collect information about the health care the patients received, including medical tests, clinic visits, or procedures both before and after participating in this study. Having more information about patient health to relate to the DNA sequences may provide new insights into cancer and its treatment.
