Recurrences After Standard EMR vs Plus Thermal Ablation EMR
Polyps of ColonRecurrence1 moreThe primary objective of this trial is to investigate whether thermal ablation EMR with soft tip snare coagulation (STSC) reduces the recurrence rate of lateral spreading or sessile polyps ≥20mm compared to standard EMR.
Length of the Proximal Resection Margin for Siewert-II/Siewert-III Tumors
Stomach NeoplasmsSiewert Type II Adenocarcinoma of Esophagogastric Junction2 moreThe incidence of adenocarcinomas of the esophagogastric junction (AEJ) has increased rapidly during the past decades. By the Siewert classification, the AEJ is the tumor center located 5 cm above the anatomic cardia and 5 cm below it, which is divided into three individual subtypes. Complete tumor resection is the primary therapy strategies for tumors of the AEJ. The Japan Clinical Oncology Group 9502 (JCOG 9502) found that transabdominal or transhiatal approach gastrectomy has better survival outcomes compared with left thoracoabdominal approach surgery for Siewert II/III tumors. Transabdominal approach gastrectomy is recommended as the standard treatment strategy for Siewert II/III tumors by the guidelines of the Japanese Gastric Cancer Association (JGCA). However, the length of the proximal resection margin for Siewert-II/III tumors by transabdominal/transhiatal gastrectomy is still controversies. Previous study found that longer than 2cm proximal resection margin had better survival outcome than less than 2cm proximal resection margin for Siewert-II/III tumors. On the other sides, due to more advanced tumor stage of patients in China when compared with Japan and Korea. It is necessary to conduct a randomized control study to analyze the length of resection margin in advanced adenocarcinomas of esophagogastric junction. Therefore, this study was aimed to include those Siewert II/III tumor patients in Gastrointestinal Surgery Department, West China Hospital, Sichuan University to analyze the relationship between the length of proximal resection margin and survival outcomes.
Comparison of Two Stapled Antimesenteric Anastomosis for CD: a Randomized Control Trial Study
Crohn DiseaseRecurrenceThe postoperative recurrence of Crohn's diseases (CD) remains high. Stapled anti-mesenteric functional end-to-end anastomosis was safe for CD patients. Its impact on the postoperative recurrence of CD was unknown. Whether it is superior than the conventional anastomosis (stapled antimesenteric isoperistaltic side-to-side anastomosis) needs explored. The trial aims to compare the different impacts of the two antimesenteric anastomosis configurations on the anastomotic recurrence following bowel resection.

Impact of Hormonal Therapy on Prostate Cancer Recurrence After Radical Prostatectomy
Prostate CancerProstate cancer is the most common cancer in men and radical prostatectomy is the most frequent treatment for this disease. Unfortunately, approximately 40% of patients will develop recurrence after surgery, requiring additional salvage radiation. Salvage radiation after recurrence is successful in less than half of these men and most of those die from their disease. Measures to prevent recurrence are an important research priority for prostate cancer patients and their families. Hormonal therapy (androgen deprivation therapy; ADT) is routinely used to treat patients with metastases, but few clinical trials have examined if adjuvant ADT after surgery will prevent cancer recurrence. We aim to address this research oversight and test the hypothesis that for men at high risk of cancer recurrence, 1 year of ADT immediately after surgery will be safe and will significantly improve cancer outcomes.
Effect of Prednisolone Treatment on Uterine Natural Killer Cells
Recurrent MiscarriageThis study aims to investigate the role of uNK cells and the association with prednisolone.
Postoperative Progression of the Disease Following Extensive Versus Limited Mesenteric Excision...
Postoperative Surgical RecurrenceThe study evaluates whether there is a reduction in the rate of postoperative progression of the disease following extensive mesenteric excision (EME), when compared to that of limited mesenteric excision (LME), in patients undergoing ileocolic resection for Crohn's disease. Half of participants will receive EME, while the other half will receive LME.
