Filter by:The Catalan Cancer Plan (CCP) undertakes periodic audits of cancer treatment outcomes, including organ/space surgical site infections (O/S-SSI) rates, while the Catalan Healthcare-associated Infections Surveillance Programme (VINCat) carries out standardized prospective surveillance of surgical site infections (SSIs) in colorectal surgery. This cohort study aimed to assess the concordance between these two monitoring systems for O/S-SSI following primary rectal cancer surgery.
The gold standard treatment for locally advanced, non-metastatic rectal cancer includes neoadjuvant chemoradiotherapy (NACRT), total mesorectal excision (TME) and adjuvant chemotherapy (AC). The primary goal of treatment is to achieve local disease control, reduce tumour volume and minimise the risk of distant metastases. While this multimodal treatment approach has offered improvements in local control and sphincter preservation, it has had little effect on distant recurrence and overall survival. We aim to compare NACRT and TME using the following endpoints: Primary -->To compare the effects neoadjuvant chemoradiotherapy versus total neoadjuvant therapy (TNT) for T3 rectal cancer on overall survival. Secondary --> To compare the effects neoadjuvant chemoradiotherapy (NARCT) and total neoadjuvant therapy (TNT) for cT3 rectal cancer on clinical outcomes: - Clinical complete response (cCR) - Pathological complete response (pCR) - Disease-free survival (DFS) - Organ preservation - Overall morbidity / mortality - Treatment-related morbidity / mortality - Peri-operative outcomes
Tumor recurrence after curative surgical resection for rectal cancer is a serious complication that greatly affects the overall morbidity and the outcome. This study aims to identify the different prognostic factors affecting recurrence and disease-free survival after surgery.
The goal of this interventional pilot trial is to confirm that Maastro endoluminal HDR ( High Dose Radiation) contact brachytherapy boosting is feasible and may increase the chance of functional organ sparing of the rectum in patients with rectal cancer. Participants will be treated with chemoradiotherapy and an endoluminal boost with the Maastro applicator.
Colorectal cancer ranks the second lethal cancer and third prevalent malignant tumour worldwide, Despite of different odern modalities for diagnosis,large number of cases diagnosed at metastatic advanced stage . New treatment approach has been discovered habe been discovered making a huge revolution in metastatic colorectal cancer represented by targeted therapy including anti_EGFR ,anti_angiogenic and kinase inhibitors .
To investigate the effects of intersphincteric resection (ISR) of ultra-low rectal tumor on the brain-rectoanal function of patients, and to precisely localize the cerebral functional regulatory regions for intervention targets of anorectal remodeling. Utilizing transcranial magnetic stimulation(TMS) technology to explore the functional remodeling of the "new" anorectal muscle groups and provide a theoretical basis for more research on the rehabilitation and mechanism of fecal incontinence.
A multicenter, cohort, randomized, controlled study is being conducted since the 1of September, 2023 whereby the immediate and long-term results of pelvic floor and perineal wound plastic surgery after extralevatory abdominal-perineal extirpation of the rectum will be compared. The study is conducted on the basis of the Federal State Budgetary Educational Institution of the Ministry of Health Care of the Russian Federation, the Department of General Surgery at the clinical base of the State Budgetary Healthcare Institution " Krasnodar Regional Hospital No. 1 named after Professor S.V. Ochapovsky" of the Ministry of Health Care of the Krasnodar Territory, State Budgetary Healthcare Institution " Krasnodar Oncological Dispensary No. 1" of the Ministry of Health Care of the Krasnodar Territory The study included patients over 18 years old suffering from cancer of the lower ampullary rectum with T1-T4N0-2M0 (according to the classification of malignant tumors TNM in the 8th edition), who are scheduled for extralevatory abdominal-perineal extirpation of the rectum. Patients are randomized into 3 groups: the first group includes patients with plastic surgery in a simple way (Plastic surgery with local tissues), the second group includes patients with plastic surgery with a mesh endoprosthesis and the third one includes patients with plastic surgery in a new way. The purpose of the study is to evaluate the effectiveness of the developed method of pelvic floor and perineal wound plastic surgery after extralevatory abdominal-perineal extirpation of the rectum. It is easily reproducible and provides high-quality closure of the deep and skin defect of the perineal wound. In addition, the new method will reduce the frequency of postoperative complications when compared with the use of conventional methods of closing the defect of the perineum, the method improves the quality of life and provides early rehabilitation of patients. Study status- patients are being recruited. Number of patients selected is 150 patients. The primary endpoint of the study is the assessment of the early postoperative period and the frequency of postoperative complications (Flap necrosis; Suppuration; Hematoma; Bleeding; Seroma) within 30 days from the date of surgery. The study was approved by the Independent Ethics Committee Protocol No. 112 of 12th November, 2022. It is planned to recruit patients within 2 years and monitor each of them for 30 days after surgery to assess the primary endpoint and to monitor patients within 1 year to assess the secondary endpoint. The secondary endpoint means an assessment of the frequency of late postoperative complications (perineal fistula, abscess, hernia) and an assessment of the quality of life within 1 year after surgery. It is planned to complete the study in 2025. Eventually it is planned to publish the protocol of the study, the results obtained after the recruitment of the required number of patients as well as the results of evaluation of the primary endpoint.
The aim of this retrospective cohort-study is to assess the effects of AL and its severity divided according the ISREC-classification on the long-term oncological outcome.
Quality of life and risk factors for developing major LARS are explored. Therapeutic options were explored in the cohort experiencing major LARS
The purpose of this study is to see which participants have a better treatment response using PET/MRI imaging to study the removed tumor, after they have received a total neoadjuvant therapy (TNT). The treatment choice of long course chemo-radiotherapy treatment will be determined by institutional policy. The researchers will also be looking at whether this study could significantly improve the future management and quality of life of rectal cancer patients.
