Filter by: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
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.
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 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.
This is an open, prospective, multi-center, single-arm phase II clinical study assessing the efficacy and safety of neoadjuvant chemoradiotherapy combined with PD-1 inhibitor and thymalfasin in patients with pMMR/MSS locally advanced middle and low rectal cancer.
Chemoradiation therapy (CRT) followed by surgery is currently the standard of care to treat patients with locally advanced rectal cancer (LARC). CRT reduces local recurrences, but is associated with significant damage to the surrounding healthy tissue that can severely impact quality of life. Additionally, a proportion of patients (hardly) benefit from CRT. We aim to develop a diagnostic innovation, which can enable a more selective and thereby more effective use of the available therapies for rectal cancer patients. The objective of this study is to investigate whether patients can be identified who will response to CRT prior to start of the CRT in rectal cancer and therefore avoid possible severe side effects in patients who will not reponse on CRT.
(1) To evaluate the oncological effects of Treatment of low locally advanced rectal cancer with radiotherapy removal TNT plus neoadjuvant therapy TNT plus mode on TRG, Anal sphincter preservation surgery rate / rectal preservation surgery rate, cCR rate, pCR rate and other oncological effects in patients with middle and low LARC; (2) Evaluate the R0 resection rate, LARS score, urination function and sexual function score, local recurrence rate, and 3-year DFS and OS of Treatment of low locally advanced rectal cancer with radiotherapy removal TNT plus neoadjuvant therapy TNT plus mode, resolve the current dispute about the Treatment of low locally advanced rectal cancer with radiotherapy removal TNT plus neoadjuvant therapy TNT treatment mode of LARC, provide a new mode for LARC treatment, and hopefully rewrite the diagnosis and treatment guidelines for rectal cancer.
The investigators conduct a single-arm, single-center, prospective clinical study enrolling patients diagnoses with pMMR / MSS type middle and low locally advanced rectal cancer who had not received systemic anti-tumor therapy to explore the efficacy and safety of short-course radiotherapy combined with furoquintinib and PD-1 monoclonal antibody as neoadjuvant therapy.
Previously, preliminary results, from a subgroup analysis of STARS-RC03 (NCT04906044) conducted by our research team, showed that the 6-cycles consolidation chemotherapy combining with anti-PD-1 therapy had a better tumor regression advantage with a restricted safety profile contrasted with 3-cycle counterparts. Herein, we designed this study to further evaluate the short-term efficacy (such as pCR rate, R0 resection rate, etc.) and long-term survival (including DFS, OS, etc.) of 6-cycles consolidation therapy.
This study aimed at comparing the Comprehensive Complication Index (CCI), readmission rates, postoperative hospitalization days, duration of bearing the stoma (months), hospitalization costs, the number of hospitalizations with ghost ileostomy versus conventional loop ileostomy after low anterior resection for rectal cancer.
