Filter by:This research study will enroll people who have cancer in their abdomen or pelvis that was treated previously with radiation therapy. The purpose of this research study is to test the safety and possible harms of treating tumors in these regions with another round of radiation therapy, called reirradiation or "reRT." The researchers want to find out what effects (good and bad) reRT has in people with cancer in the abdomen and pelvis.
Evaluation of clinical and dosimetric aspects, tolerance, and effectiveness of abdominal-pelvic region radiotherapy treatments in patients undergoing radiotherapy for primary or secondary neoplasms localized in the tabdominal-pelvic region.
Cone beam computed tomography (CBCT) images are routinely used in radiation treatment delivery workflows to align patients with the treatment beam. Conventional CBCT image quality is sufficient for this task but not good enough for other radiotherapy-related tasks, such as contouring anatomical structures and calculating radiation dose distributions. HyperSight is a new CBCT imaging system manufactured by Varian Medical Systems. The purpose of this study is to evaluate the integration of the HyperSight imaging system with Varian's TrueBeam radiotherapy system, a linear accelerator with a C-arm gantry that rotates about the patient to delivery radiation to the target malignancy. HyperSight CBCT images will be acquired prospectively from patients who are receiving radiation treatment. The HyperSight/TrueBeam system will be used for imaging only; patients receive their radiation treatment on cleared devices and no aspect of their treatment is affected by participation in the study. HyperSight images collected during the study will be evaluated for quality and utility and compared to conventional CBCT images as well as fan beam CT images used for treatment planning.
Retrospective and prospective observational study of patients undergoing advanced pelvic oncological resection for maligancy including multi visceral resection, beyond TME resection and sacrectomy/flap reconstruction/urinary reconstruction at Glasgow Royal Infirmary. Goal is to study and report outcomes for patients to characterise and understand major complications, natural history of resectional patients and identify areas for future interventional study.
In a transvaginal tru-cut biopsy, guided by ultrasound, a needle is inserted through the vaginal wall into a pelvic lesion and a few pieces of tissue are obtained for examination. This clinical trial is organized to evaluate the safety and efficacy of transvaginal tru-cut biopsy in a large group of patients with tumors in the small pelvis.
Advanced pelvic cancers are uncommon, with treatment being challenging. Around 4000 patients every year need treatment in the UK. Cancers can involve multiple organs and often need radiotherapy and chemotherapy before surgery. Surgery usually requires removal of multiple pelvic organs, including muscles, bone, and skin around the anus (the perineum). This can lead to complications relating to both the empty pelvis syndrome and closure of the perineal defect. Reconstruction is challenging, with frequently occurring complications, reducing speed of recovery and quality of life. This study investigates complication frequency, quality of life and expenses following different reconstruction techniques. The investigators hope to improve patient and doctor decision-making in this area and find the best methods of reconstruction to improve outcomes. REMACS has three work packages: 1. Maintenance of a database of patients undergoing colorectal surgery at Southampton and Salisbury Hospitals, including those undergoing extra-levator abdominoperineal excision and pelvic exenteration. This includes clinical data, imaging, health resource use, and patient reported outcome measures. 2. A collaborative national prospective cohort study investigating morbidity, health resource use, longitudinal quality of life outcomes (EORTC QLQ-C30 and disease-specific modules) and quality adjusted life years. The investigators will also assess financial toxicity using the comprehensive score for financial toxicity. 3. A qualitative study using semi-structured interviews to undertake a more complex evaluation of quality of life and patient experiences in patients that have recovered from their surgeries.
Pediatric Oncologic Recovery Trial After Surgery (PORTS) trial is an investigator-initiated, multicenter, multidisciplinary prospective case-control study of the implementation of an Enhanced Recovery After Surgery (ERAS) protocol at five tertiary-care pediatric hospitals in pediatric patients undergoing abdominal or retroperitoneal surgical resections for cancer. A pilot phase will determine characteristics of a successful protocol implementation and an exploratory phase plans to examine adherence, objective patient outcomes, and patient-reported outcomes. After completing primary enrollment, this collaborative will continue to enroll patients in the shared data registry and continue to refine the underlying ERAS protocol developed for this project.
Aim of the study is to assess efficacy of a short course radiation treatment in patients with symptomatic pelvic malignant lesions
The hypothesis of the study is that high intensity focused ultrasound (HIFU) can be used safely to treat rectal and pelvic cancer. The study consists of two trials exploring the use of HIFU in rectal and pelvic cancer to establish the safety and potential efficacy of HIFU in this instance. The first trial is a feasibility study looking at patients with early rectal cancer. We aim to recruit thirty patients with early rectal cancer who are due to undergo an operation to remove their cancer. After recruiting and consenting them for the trial, we will treat their rectal cancer with HIFU. Approximately one week after treatment they will undergo their normal cancer operation. This will allow us to demonstrate the safety of HIFU as a treatment for rectal cancer and evaluate the changes in rectal and surrounding tissue under the microscope after the cancer is treated with HIFU. In addition, we will monitor patients for any complications and the impact this treatment has on their quality of life. We will monitor the response of various markers for cancer with blood tests. The second trial aims to evaluate the treatment of a cohort of patients with inoperable rectal cancer. We aim to recruit thirty patients with either inoperable pelvic cancers - rectal, cervical or endometrial, or cancers that have returned after previous operations. We will offer these patients treatment of their cancer using HIFU. We will monitor the symptoms they experience and impact on their quality of life both before and at multiple time points after the treatment with HIFU. We will compare MRI scans before and after treatment to evaluate the effect HIFU has in reducing the size of the cancer. We hope to show that using HIFU in this group of patients can be both effective and lead to an improvement in both their symptoms and quality of life.
To validate a new method for assessing perioperative risk in the cancer patient undergoing major cancer surgery. In this proposed study researchers will: 1. Measure preoperative energy reserve capacity (fitness) 2. Determine if postoperative morbidity is a function of perioperative cardiopulmonary gas exchange metabolism
