Adenocarcinoma of the RectumStage II Rectal Cancer1 more

Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining chemotherapy, radiation therapy, and surgery may be a more effective treatment for cancer of the rectum. Phase II trial to study the effectiveness of combining oxaliplatin, fluorouracil, and external-beam radiation therapy followed by surgery in treating patients who have locally advanced cancer of the rectum

Interleukin-12 and Trastuzumab in Treating Patients With Cancer That Has High Levels of HER2/Neu...

Advanced Adult Primary Liver CancerAnaplastic Thyroid Cancer125 more

Interleukin-12 may kill tumor cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill cancer cells. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Phase I trial to study the effectiveness of interleukin-12 and trastuzumab in treating patients who have cancer that has high levels of HER2/neu and has not responded to previous therapy

Total Neoadjuvant Treatment Without Surgery For Locally Advanced Rectal Cancer

Colo-rectal Cancer

NO-CUT is a one-stage phase II trial seeking to establish whether an oxaliplatin-based chemotherapy preceding standard neo-adjuvant fluoropyrimidines-based chemo radiotherapy, can safely spare demolitive surgical intervention in patients with operable rectal cancer, without increasing the risk of distant relapse. The trial also has a translational component aimed at establishing whether selected genomic, epigenetic, and transcriptomic markers are predictive of tumor and patient outcome.

Robotic-assisted Versus Conventional Laparoscopic Approach for Rectal Cancer Surgery

Rectal Cancer

This is a prospective randomized controlled study that was conducted on patients of both sexes and definite age group at National Cancer Institute-Egypt and with adenocarcinoma of the rectum located within 15 cm from the anal verge. Tumor localization was categorized as the upper rectum (distal border of tumor is from 10 to 15 cm from the anal verge), middle rectum (5 to 10 cm from the anal verge) or lower rectum (less than 5 cm from the anal verge) as measured by colonoscopy and digital rectal examination. Patients were classified into two groups; robotic assisted rectal surgery and conventional laparoscopic rectal surgery.Baseline demographics (gender, age, ASA, BMI), preoperative data (distance of the tumor from the anal verge, clinical stage, whether preoperative chemoradiation (CRT), presence of residual tumor after CRT, intraoperative data (preparation time, actual operative time, estimated blood loss, conversion rate to open surgery), postoperative data (pathological stage, number of harvested lymph nodes, macroscopic completeness of resection in the form of proximal margin, distal margin, circumferential radial margin) and immediate postoperative outcome within one month (days of return of bowel function, days of hospital stay, complications, if any, like anastomotic leakage, ileus,wound problems and others, rate of re-operation, rate of readmission & 30-days mortality) were analyzed and compared.The criteria for patients selection were the following: histological diagnosis of adenocarcinoma of rectum, no anesthesiological contraindications to minimally invasive surgery, age ≤ 75 years, American Society of Anesthesiologists (ASA) ≤ 2 & the procedures performed by the same surgical team. Patients with metastatic disease, malignant bowel obstruction and those with irresectable tumor were excluded from our study.Preoperative workup (endoscopy with biopsies, radiological imaging including pelvic MRI, liver ultrasound, chest X-ray and routine abdominal and digital rectal examinations) was routinely carried out. The assignment of patients to either group was done by a permuted block randomization. It was an open-labeled study. The study was approved by the institutional review board of National Cancer Institute-Cairo University. All patients provided written informed consent.

Open or Laparoscopic Mesolectal Excision in Low Rectum Cancer

Rectal Cancer

To compare the open approach and the laparoscopic-assisted approach of dissection of lateral lymph nodes in low advanced rectal cancer patients with clinically suspected nodal metastases in terms of safety, technical feasibility, and patient's oncological outcomes.

Video Analysis of Errors and Technical Performance Within Minimally Invasive Surgery Short Title:...

Prostate CancerRectal Cancer

Despite the high volumes, advanced minimally invasive surgery is non-standardised and variations often occur in surgical technique, performance, delivery, team communication, and surgical approach. Such variations can result in errors and complications that can potentially be avoided. This project aims to analyse surgical phases (stage of the operation), skill and errors to anonymised, surgical video data through Medtronic's Touch Surgery™ Enterprise DS1 Computer which can capture video data anonymously in any minimally invasive (key hole) procedure in the operating room, allowing immediate, upload of data to a platform for immediate feedback and assessment to surgeons. The investigators hypothesise that understanding technical performance and surgical processes, may reduce unwarranted variations, errors and near misses, and improve the performance of the entire surgical team that is ultimately hoped to enhance patient safety and outcomes. Investigators plan to develop assessment tools with the hope to improve feedback, learning and ultimately surgeons' performances. The latest methodology of manual (OCHRA) and automated assessment (artificial intelligence) will be applied. Investigators aim to validate these methods by correlating video "scores" of skill/errors to patient outcomes e.g. complications, cancer outcome.

ctDNA and Organ Preservation/Pathologic CR in Rectal Cancer

Rectal CancerNon Metastatic Rectal Cancer

This prospective observational, non-therapeutic study for patients with T3, T4, or node positive rectal cancer eligible to undergo total neoadjuvant therapy. This research study involves the collection of data and biospecimens (blood and tissue) to see if the presence of circulating tumor DNA (genetic material) ctDNA will help monitor rectal cancer more closely and potentially detect a recurrence before routine scans, performed per standard of care C2i Genomics, a biotechnology company, and the Spier Foundation are supporting this research study by providing funding for the study.
