Filter by: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.
The large intestine is the last part of the digestive tract. It absorbs water and dietary substances. However, it is also where most of our bacteria are resident. These bacteria are important for our health and influence many different diseases, including Colon Cancer, Ulcerative Colitis and Crohn's disease. The gut bacteria can also potentially influence responses to treatments in other cancers by helping to change the responses to radiotherapy and chemotherapy. The interactions between these bacteria and the rest of our cells are only now becoming understood and there is little research on the interactions between these bacteria and cancer radiotherapy treatments in pelvic cancer. We will therefore explore this in more detail. We will ask for samples of the patient's poo before their treatment for pelvic cancers. This will include patients with bladder, prostate, cervical, ovarian, womb or colorectal cancers. By doing so we will be able to compare the profile of gut bacteria with responses to treatments, thereby increasing our understanding of the colonic bacteria. To do this we process the poo specimens to remove the bacterial genetic material (DNA) of the bacteria and process it on a machine to read the genetic code and also study the metabolites that they will produce. We can then make a direct comparison between different samples of the relative numbers of different bacteria present. In some cases, we will compare this to metabolites and inflammatory and immune markers identified in a blood sample. This work might help future patients by determining what are the best bacteria to have in the colon during cancer treatments. These could potentially be given to patients, before their cancer treatment, in the form of probiotic medications, should there be an improvement demonstrated in our research. Alternatively we could alter the patients' intakes of specific dietary fibres to boost these bacteria specifically.
This is a feasibility study investigating the image quality of a new, high-performance cone beam CT (CBCT) used for on-couch imaging during radiotherapy treatments.
In recent years, template guidance has been applied and developed in the field of puncture related operations, such as template-assisted radioactive seed implantation. With the guidance of template, needle pathway of seed implantation, biopsy and fiducial marker implantation can be precisely planned actual operation, which is conducive to the accurate proceeding. Templates can be divided into coplanar templates and non-coplanar templates. The digital coplanar template coordinate puncture system has been developed in China and has been applied in clinical practice. In previous studies, coplanar template assisted CT-guided radioactive seed implantation has good clinical feasibility for head and neck cancer. However, the accuracy of Coplanar Template Assisted Seed Implantation for Abdominal and Pelvic cancer are lacking in prospective studies. The study aims to prospectively observe the accuracy and safety of Coplanar Template Assisted Seed Implantation for Abdominal and Pelvic cancer.
In France, according to the National Cancer Institute, it appears that treatments in radiotherapy centers for cancer will increase from 198,000 in 2015 to 239,000 in 2030: this represents 40,000 additional treatments in 15 years. A meta-analysis on radiotherapy indicated that 10 to 20% of patients had clinically significant levels of anxiety at the beginning of radiotherapy. Indeed, several factors generate this tension, above all the new or unfamiliar environment, the imposing and noisy scanner, the restraints that are difficult to bear or the nudity required for the examination. This anxiety has an impact on performance of the planning CT scan examination, an essential step for the future treatment. The radiotherapy unit of the Centre Hospitalier Departemental de Vendee has put in place resources to reduce anxiety felt during treatment sessions (music therapy, conversational hypnosis, sophrology or aromatherapy). However, nothing has been put in place to reduce the anxiety of patients in the period preceding the planning CT scan. Virtual reality software seems to be a good alternative that requires fewer human resources. The research hypothesis is that patients who have benefited from the virtual reality software will have a lower level of anxiety before the planning CT scan than patients who have not benefited from virtual reality.
In image-guided radiotherapy (IGRT), the repeated and increasingly intensive use of on-board positioning imaging, using 2D or 3D Mega-Volt (MV) or kilo-Volt (kV) imaging devices (cone-beam or CBCT scanners), is leading the international medical community to question the potential impact of these additional doses delivered to the patient, especially in at-risk populations such as children and young adults. The doses delivered to the patient by positioning imaging are still relatively unknown, due to the lack of experimental means and software available in clinical routine to easily and accurately evaluate these doses. The main objective is to estimate by personalized Monte Carlo calculation the physical doses delivered to the patient's organs by the onboard imaging systems during their radiotherapy treatment. The obtained imaging doses will be compared according to different irradiation scenarios commonly used in clinical routine as well as according to the treated location.
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.

The superior hypogastric plexus (SHP) is a complex nervous collection located at the lumbosacral region below the level of the aortic bifurcation at the level of the lower third of the fifth lumbar vertebral body and upper third of the first sacral vertebral body at the sacral promontory Neurolytic agents, such as alcohol and phenol have been used to ablate peripheral nerves to treat pain and spasticity . These agents were nonspecific for neuronal tissue and complications have been seen involving damage to surrounding soft tissue (skin, muscle, vascular) and pain on alcohol injection Lidocaine has been demonstrated to be neurotoxic in high concentrations at 10% and can be used as a neurolytic agent with no effect on motor function, muscle state, or surrounding tissue rather than other neurolytic.
This study aims to determine the functional outcomes of patients who underwent internal hemipelvectomy with or without reconstruction or external hemipelvectomy for pelvic tumors. Learning about the outcomes of these patients may help researchers determine the long-term effects of different types of hemipelvectomy procedures and may help improve quality of life.
