Filter by: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.
The investigators hypothesize that two pelvic relaxation exercises will be feasible and safe to perform by subjects daily before radiation during the participant's treatment and will decrease variability of sacral slope measurements on daily port films. The investigators will observe trends in the daily variability and change in the sacral slope in each participant to determine if this could decrease variability. The investigators will compare these measurements to a retrospective cohort that did not have the exercises, but did demonstrate variability. Reducing set-up variability (which inadvertently occurs during radiation) is important to improve radiation targets and diminish potential adverse effects. The investigators will query participants for objective and subjective feedback on the exercises and record frequency and duration of the two exercises.
The aim of the present project is to investigate whether use of biological mesh at the donor site of the rotation flap in closure of the abdominal wall reduce the frequency of incisional hernia formation compared to the usual abdominal wall closure after abdominal rotation flap operation in surgery for advanced pelvic cancer.
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
Phase I study. Side-effects when combined with standard palliative radiotherapy.
This study is using the combination of radiation and antiangiogenic agents (agents that destroy existing blood vessels) seems to be an approach to tumor cure.
This multi-center photodynamic therapy study plans to treat patients with large tumors in any superficial location, sarcoma, tumors of oral/oro-pharyngeal cavity, tumors with extensive pelvic involvement, or liver metastasis. The treatment is limited to patients that have failed to respond to currently approved methods of treatment. The study involves a single, intravenous administration of an investigational drug, LS11 (previously studied in approximately 80 cancer patients) and the placement of a novel, flexible light delivery catheter inside the tumor by a minor surgical procedure. The activation of LS11 by the light delivery catheter over a period of 1-24 hrs may result in destruction of tumor tissue.
