Filter by:Mid to low-lying rectal cancer patient with enlarged lateral lymph node befor treatment and receiving lateral lymph node dissection would be enrolled. Radiomics parameters of lateral lymph nodes would be extracted by expert software. Then a part of the nodes would be used as the training set to build the prediction model, and the another part nodes would be used as the validation set.
A magnetomotive ultrasound combines standard diagnostic ultrasound equipment with the application of an external time-varying magnetic field. The investigators aim to use this equipment to improve preoperative diagnostics in rectal cancer.
Patients with sphincter saving procedures of rectal cancer usually experience intestinal dysfunction, including difficulty emptying the bowel and faecal incontinence, leading to a detriment in the quality of life. A prospective study is proposed to measure de feasibility and the impact of a continuous care programme for the prevention or reduction of intestinal dysfunction disorders. The intervention lies on prehabilitation and rehabilitation with physiotherapy, biofeedback and neuromodulation, is assisted by a telematic information system (APP for the monitoring of education on physiotherapy and surveillance).
The purpose of the study is to determine if short-term outcomes of rectal resections after full bowel preparation (mechanical bowel preparation plus oral antibiotics) are superior to rectal resections with only mechanical bowel preparation.
This RCT aims at assessing the effects of a pelvic drain after total mesorectal excision for mid-low rectal cancer on the rates of pelvic sepsis and anastomotic leaks.
This study is designed to investigate long-term oncologic outcomes of single-incision laparoscopic surgery (SILS) compared to conventional laparoscopic surgery (CLS) for colorectal cancer.
To investigate a potential toxicity benefit of preoperative radiation therapy with protons compared to conventional photon beam radiation therapy in patients with locally advanced rectal cancer.
This is a multicenter, prospective, randomized, stratified, controlled, open-label study comparing preoperative FOLFOX versus postoperative risk-adapted chemotherapy in patients with locally advanced rectal cancer and low risk for local failure
Local recurrence rates in rectal cancer have reduced dramatically since the introduction of the total mesorectal excision (TME) technique and neoadjuvant (chemo)radiotherapy (C))RT) to overall rates of 5-year local recurrence to 5-10%. However, distal rectal cancers have a tendency to spread to lateral lymph nodes and it was recently shown that patients with enlarged lateral lymph nodes of ≥7mm short-axis size have a considerable chance of a local recurrence: 15-20%. This is regardless of CRT with TME in two retrospective cohorts (Lateral Node Consortium and Snapshot Rectal Cancer 2016 study). According to the Lateral Node Consortium study, this rate was significantly reduced to <6% when performing a lateral lymph node dissection (LLND) after (C)RT + TME. A major drawback of these recent multi-center studies is their retrospective nature. Therefore, in the Netherlands, radiologists, radiation oncologists, surgeons and pathologists have recently been educated and trained to enhance knowledge and awareness of LLNs and to implement nerve-sparing minimally invasive LLND. The LaNoReC trial is a prospective registration study aimed at evaluating oncological outcomes after multi-disciplinary training. The main question of this study is whether, after dedicated training and the performance of LLNDs, the lateral local recurrence rate in rectal cancers with enlarged nodes (≥7mm) can be reduced to below 6%.
Advances in the treatment of rectal cancer over the past two decades have improved survival and significantly reduced surgery-related morbidity. As a result, post-treatment quality of life (QoL) issues have become increasingly important. Urinary and sexual functions can be significantly altered after rectal resection, mainly due to the iatrogenic lesions of the pelvic autonomous lexus. Of note, their incidence is reported up to 70% and 30%, respectively. Despite the importance of this topic, most of the studies present in the literature are difficult to interpret for a variety of reasons. Firstly, both sexual and urinary dysfunctions lack a standardized definition. Secondly, the absence of baseline data, missing data, small sample sizes, and heterogeneity in the use of validated and nonvalidated instruments are the main limitation in drawing conclusive results. As additional factor, no clear evidence is present in the literature regarding the best approach to be used in order to preserve as much as possible both the sexual and urinary functionalities and to guarantee, at the same time, an adequate and oncologically correct rectal resection. Moreover, no data are currently present regarding the impact of pre-operative chemo-radiotherapy on the urinary and sexual functionalities. The main objective of the investigator's prospective study will be to define in a subjective manner which technique (open, laparoscopic, robot-assisted and Ta-TME) will guarantee the best urinary and sexual outcomes after rectal resection (with or without pre-operative chemo-radiotherapy) for the treatment of rectal carcinomas. Thus, the primary endpoint will the post-operative evaluation at 1, 6 months and 1 year of the urinary and sexual functions by means of specific questionnaires. Secondary endpoints will be: - to investigate which technique (open, robotic, laparoscopic and trans-anal total mesorectal excision (TaTME)) more favorably correlate with urinary and sexual functions after radiochemotherapy (NAD+); - the comparison of both the urinary and sexual dysfunction incidence on the base of the distance of the rectal tumor from the anal verge and the evaluation of the best approach to be used (open, laparoscopic, TaTME or robot-assisted) in relation to the tumor height; - the short- (postoperative morbidity and histopathological data) and long-term (overall and disease-free survival) outcomes comparison among the open, laparoscopic, TaTME and robotic rectal resection.
