A Randomized, Controlled, Multicenter, Noninferiority Clinical Study of Perioperative and Oncological Safety in Patients With Rectal Cancer

ABSTRACT: Laparoscopic natural orifice specimen extraction surgery (NOSES) for low rectal cancer has a good minimally invasive effect. However, the NOSES prognosis studies are all small sample retrospective studies. This study conducted a multicenter prospective randomized controlled trial of NOSES surgery for low rectal cancer to compare the difference in surgical outcomes between conventional laparoscopic surgery and NOSES surgery for low rectal cancer. A total of 500 patients were planned to be enrolled, including 250 in the control group and 250 in the experimental group. The primary end point was 2-year disease-free survival (DFS), and the secondary end points were surgical safety, postoperative pathology, postoperative defecation, urination, and sexual function. Through a large sample size study, this study aims to clarify the advantages of NOSE surgery for low rectal cancer, promote the promotion of low rectal cancer NOSES surgery in the country, standardize the way of low rectal cancer NOSES surgery, improve the surgical treatment of patients with low rectal cancer, improve the quality of life of patients, reduce the burden of patients, and increase the satisfaction. And improve the international influence of the project team in the field of minimally invasive surgical treatment of colorectal cancer.

Comparison of NOSES and Conventional Laparoscopic Surgery in Colorectal Cancer

Project description:Radical surgery for rectal cancer has evolved from the initial concept of total mesorctal excision (TME) to the wide application of laparoscopic surgery in the radical treatment of rectal cancer. After 30 years’ rapid development, nowdays laparoscopic TME surgery for rectal cancer has become the first choice for those patients with rectal cancer. However, the auxiliary incision of the abdominal wall which is used to remove tumor specimens is contrary to the current concept of minimally invasive surgery. Avoiding abdominal wall incisions has become a common appeal of gastrointestinal surgeons and patients with rectal cancer. Natural orififice specimen extraction surgery (NOSES) can solve the problem of abdominal wall auxiliary incision, which complete rectal cancer radical resection and gastrointestinal reconstruction under the full laparoscopic. The specimens are taken out through the natural orifice (rectum or vagina) without an auxiliary incision, which is more in line with minimally invasive practice and easier to operate. Researching on the progress of laparoscopic radical resection of rectal cancer in NOSES aims to provide a certain reference for this operation.

reprogramming enables the auxiliary diagnosis of breast cancer by automated breast volume scanner

Project description:Our study identified metabolic features both in benign and malignant breast tumors and in invasive and non-invasive breast cancer. Combined ultrasound ABVS and a panel of differential serum metabolites could further improve the accuracy of preoperative diagnosis of breast cancer and guide surgical therapy

Changes in Coagulation in Colorectal Cancer Patients Undergoing Surgical Treatment

Project description:Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) has prolonged the survival substantially for selected patients with peritoneal metastases from colorectal cancer.Bleeding and thromboembolic disease have been reported as postoperative complications related to this advanced open surgical treatment. However, perioperative changes in coagulation and fibrinolysis are only sparsely reported in the literature.The mainstay of treatment with curative intend of none-advanced colorectal cancer is minimally invasive laparoscopic surgery followed by adjuvant chemotherapy. The approach is considered associated with a lower risk of thromboembolic disease than open surgery. Despite differences in extent of surgery and thromboembolic risk the same extended thromboprophylaxis regimen for 28 days is currently prescribed to patients undergoing cytoreductive surgery with HIPEC as well as minimally invasive rectal cancer resection. This study aims to investigate all parts of the coagulation system and fibrinolysis, and thereby thromboembolic risk and potential bleeding in two groups of patients with different extent of surgical trauma: 1) Colorectal cancer patients undergoing cytoreductive surgery with HIPEC and 2) rectal cancer patients undergoing minimal invasive rectal cancer resection. Our hypothesis is that patients undergoing cytoreductive surgery with HIPEC are exposed to more aggravated alterations of coagulation and fibrinolysis than patients undergoing minimally invasive rectal cancer resection.

Porcine gene response following incision with energized devices

Project description:This study compares the gene expression changes in Sus scrofa in response to two different methods for abdominal surgical incisions ; electrosurgery and harmonic blade. As the use of laparoscopic surgery has become more widespread in recent years, the need has increased for minimally-invasive surgical devices that effectively cut and coagulate tissue with reduced tissue trauma. Although electrosurgery (ES) has been used for many generations, newly-developed ultrasonic devices (HARMONIC® Blade, HB) have been shown at a macroscopic level to offer better coagulation with less thermally-induced tissue damage. We sought to understand the differences between ES and HB at a microscopic level by comparing mRNA transcript and protein responses at the 3-day timepoint to incisions made by the devices in subcutaneous fat tissue in a porcine model

Detection of pancreatic ductal adenocarcinoma-associated proteins in serum

Project description:Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancer types, partly because it is frequently identified at an advanced stage, when surgery is no longer feasible. Therefore, early detection using minimally invasive methods such as blood tests may improve outcomes. However, studies to discover molecular signatures for the early detection of PDAC using blood tests have only been marginally successful. In the current study, a quantitative glycoproteomic approach via data-independent acquisition mass spectrometry (DIA-MS) was utilized to detect glycoproteins in 29 patient-matched PDAC tissues and sera. Total of 892 glycopeptides originated from 141 glycoproteins had PDAC associated changes beyond normal variation. We further evaluated the specificity of these serum detectable glycoproteins by comparing their abundance in 53 independent PDAC patient sera and 65 cancer-free controls. The PDAC tissue-associated glycoproteins we have identified represent an inventory of serum detectable PDAC glycoproteins as candidate biomarkers that can be potentially used for the detection of PDAC using blood tests.

The test devices were monopolar electrosurgery and Harmonic blade. Each animal had two Harmonic Blade incisions and two Electrosurgery incisions for a total of 8 incisions

Cell-free DNA 5-hydroxymethylcytosine for immunotherapy response prediction in lung cancer

Project description:Immune checkpoint inhibitors (ICIs) drastically improve therapeutic outcomes for lung cancer, but accurate prediction of individual patient responses to ICIs remains a challenge. We performed a genome-wide analysis of 5-hydroxymethylcytosine (5hmC) in plasma cell-free DNA (cfDNA) samples from 83 lung cancer patients. Using machine learning approaches, we developed a 5hmC signature to predict ICI treatment response and calculated a weighted-predictive score (wp-score) based on the 5hmC levels of signature genes in each sample. A low wp-score was significantly correlated with longer progression-free survival across three independent patient sample sets, and demonstrated superior predictive capability to tumor programmed death-ligand 1. Moreover, we identified novel 5hmC-associated genes and signaling pathways integral to ICI treatment response in lung cancer. Our study suggests that cfDNA 5hmC analysis is a minimally invasive, innovative strategy for guiding treatment selection in lung cancer patients.
