Study evaluating the activity and efficacy of Stereotactic Body Radiotherapy for the treatment of medically inoperable localized renal cancer
Minimally-invasive surgery, either laparoscopic or robotic, is commonly used in urology. Several urologic procedures including prostatectomy, radical nephrectomy, and partial nephrectomy are now commonly performed robotically. Patients undergoing these procedures often have delayed return of bowel function and persistent gastrointestinal symptoms including nausea/vomiting, abdominal distension, and bloating for several days to weeks after surgery. Postoperative stool softeners and laxatives are routinely used in an effort to minimize these symptoms, with varying degrees of success. The aim of this study will be to evaluate whether the use of a preoperative osmotic laxative will be beneficial in improving recovery of bowel function and alleviating postoperative gastrointestinal complaints in patients undergoing these procedures. Patients will be randomized to either receive or not receive three days of polyethylene glycol (PEG, also known as MiraLAX) on the three days before surgery. Patients in both groups will receive the same postoperative bowel regimen including scheduled PEG both in the hospital and upon discharge until first bowel movement. Patients will be given a questionnaire and diary to record their postoperative gastrointestinal symptoms and time to first bowel movement. These questionnaires and diaries will then be analyzed to determine differences in time to first bowel movement and gastrointestinal complaints during their recovery from surgery.
The aim of the study is to find out whether supervised physical exercise during cancer drug treatment improves the effectiveness of the treatment in metastasized breast, kidney, ovarian and prostate cancer compared to unsupervised exercise. In addition, the investigators are investigating whether the use of atorvastatin combined with guided group exercise training would further improve the response to cancer treatment.
Partial nephrectomy(PN) and tumor enucleation(TE) are the two main methods of Nephron-sparing surgery for early renal cell carcinoma. Because of its blunt separation, TE is often considered to be difficult to completely remove tumor tissue. In addition, compared with PN, TE is more difficult and has higher professional requirements for surgeons. Therefore most surgeons use PN. But Many studies have shown that TE has advantages over PN such as less trauma, faster recovery, and better protection of renal function without increasing the risk of tumor recurrence. The main renal artery should be clamped during PN to achieve a relatively bloodless operation environment to ensure the safety of tumor resection. However, too long warm ischemia time will inevitably affect the function of normal renal tissue. Studies have shown that shortening the time of renal ischemia is closely related to the recovery of renal function after the operation. So reducing the time of warm ischemia until zero ischemia has become the pursuit of surgeons. Based on renal cell carcinoma resection combined with zero ischemia technique, renal parenchyma, and renal function can be protected to the maximum extent on the premise of ensuring tumor safety. The purpose of this study is to explore the safety and efficacy of zero-ischemia TE by analyzing the data of early renal cell carcinoma patients who had undergone PN and zero-ischemia TE before.
The aim of the present study is the identification, in liquid biopsies, of a new molecular panel able to discriminate renal cancer patients from controls, to discriminate patients with a malignant lesion from those with a benign mass, to determine aggressiveness of RCC, and to differentiate the most common histological subtypes of RCC (clear cell, papillary 1, papillary 2, and chromophobe). This new molecular panel will be combined with clinical parameters to provide a screening test and to improve the accuracy and specificity of diagnosis, prognosis, and histological classification of renal cancer.
The choice of the best strategy in treatment-naive metastatic clear-cell renal cell carcinoma (mccRCC) patients is becoming an issue, since no biomarkers are available to guide the treatment allocation strategy. The elucidation of predictive factors to develop tailored strategies of treatment is an urgent unmet clinical need. Recently there has been a great deal of interest in non-invasive liquid biopsy methods for their ability to detect and characterize circulating cell-free DNA (cfDNA), extracellular vescicles associated RNAs and circulating tumor cells and to allow longitudinal evaluation of tumor evolution. An additional field of intense research is also radiomics as a novel approach to develop predictive tools by correlating imaging features to tumor characteristics including histology, tumor grade, genetic patterns and molecular phenotypes, as well as clinical outcomes in patients with renal neoplasms. The use of computational approaches to integrate informations, obtained from genomic and transcriptomic analysis of neoplastic tissues and of cfDNA) or microvescicle-associated RNA in blood and from radiomics, can be exploited to define an optimal allocation strategy for patients with mccRCC undergoing first-line therapy and to identify novel targets in mccRCC. Aims of the study are: to identify molecular subtypes, signatures or biomarkers in mccRCC associated with different clinical outcome by applying bioinformatic analysis; to extract descriptive features in mccRCC from radiological imaging data; to integrate omics-driven and clinic-pathological characteristics with radiomic features extracted from the tumor and tumor environment to inform on biological features relevant to therapy outcome. This multicentric prospective study will evaluate genomics and radiomics in treatment-naïve advanced ccRCC patients. 100 eligible patients will be identified after screening, candidate to receive first-line treatment as investigator choice per clinical practice. Tissue and plasma samples and CT exams will be collected at different intervals to provide a comprehensive molecular profile and radiomic features extrapolation, respectively. Artificial neural networks will be used to build a genomic-radiomic profile of patients to correlate to treatment response. This sample size will allow an exploratory analysis of the prognostic and predictive performance of the multiomic classifier, to be subsequently validated in a larger expansion cohort of patients.
BACKGROUND: The role of cytoreductive nephrectomy (CN) in the treatment of metastatic renal cell carcinoma (mRCC) has been questioned and remains undetermined in the immuno-oncology era. Results from the two randomized trials, CARMENA and SURTIME, have questioned the role and timing of the surgery in these patients, however, these trials have only used the targeted therapy, sunitinib. With the advent of more effective systemic therapies including immune checkpoint inhibitors (ICIs), the role of surgical therapy should be reexamined. RATIONALE: The therapeutic effects of ICIs have demonstrated improved oncological outcomes compared to sunitinib. The updated results reported the beneficial role of upfront and deferred CN approach for selected patients. No studies have formally investigated the role of CN in the immune-oncology era where combinatorial use of CN plus ICIs might be beneficial. HYPOTHESIS: Upfront or deferred CN will improve oncological outcomes (overall survival, and progression free survival) in patients with synchronous mRCC and ≤3 IMDC risk features compared to immune checkpoint inhibitors (nivolumab plus ipilimumab combination) alone. This is an open, randomized, multicenter comparison trial, designed to evaluate the effect of the potential role of CN in combination with immunotherapy in mRCC patients with IMDC intermediate and poor risk.
Indocyanine Green (ICG) is a dye which fluoresces under near-infrared (NIR) light. It has been used for several applications in adult surgery. The CI is pioneering its use in children's kidney cancer surgery for lymph node identification and removal. This study concentrates on its use for procedures where only the part of the kidney containing tumour is removed. It is known that kidney tumours in both adults and children do not take up ICG at all. This absence of uptake can be used to define the border between normal and abnormal renal tissue giving a real-time picture of the area of tumour. This then delivers surgeons an intra-operative roadmap for removing only the cancerous part of the kidney. At present the international society of paediatric oncology - renal tumour study group (SIOP-RTSG) protocol, which is followed in the UK, advises consideration of partial nephrectomy for children with bilateral renal tumours and in children with unilateral tumours who have a renal tumour predisposition syndrome. There is ongoing debate about partial nephrectomy in unilateral renal tumour surgery in children who do not have a predisposition syndrome. This study aims to provide the evidence that paediatric renal tumours do not take up ICG at a naked-eye level and confirm this at a cell level. ICG will be infused into kidneys containing tumour once they have been removed from the patient, The kidney and tumour will be observed under NIR light to show where the areas of fluorescence are. Then, a pathologist will prepare the specimen in theatre, in the same way they would do in the lab. The specimen would be bivalved and reviewed under NIR. Microscopy specimens of the border between normal and abnormal tissue would then be reviewed with an NIR capable microscope. The standard histopathological assessment would then take place.
The goal of this clinical trial is to compare two kind of trocar in patients undergoing complex robot-assisted partial nephrectomy. The main question it intends to answer is whether the use of valveless trocars can significantly reduce carbon dioxide absorption.
