Filter by:There is a controversy regarding the effect of the two Body Mass Index (BMI) extremes on the oncological outcome of rectal cancer. The obesity paradox appears to exist in rectal cancer patients treated with nCRT and surgery, as it was associated with significantly higher rates of pathological complete response and R0 resection. Underweight patients were at higher risk for anastomotic leak and R1 resection.
The aim of the present prospective, comparative study was to compare the quality of life (QoL) of patients after colorectal surgery to the QoL of their spouses. The study included patients who underwent curative surgery for colorectal carcinoma (n = 100; abdominoperineal excision [n = 33], low anterior resection [n = 33], left hemicolectomy [n = 34]) and their spouses (n = 100). The patients and spouses completed the Medical Outcome Study 36-item Short Form Survey (SF-36) and the World Health Organization Disability Assessment Schedule II (WHODAS-II) preoperatively and at postoperative months 15 to 18. The QoL of patients and that of their spouses changed following surgery for colorectal cancer. These changes were more significant among male patients' spouses.
This study will facilitate a better understanding of the overall experience of our rectal cancer survivors after Low Anterior Resection for rectal cancer. Studies have demonstrated that the development of bowel and genitourinary dysfunction after this procedure is very distressing to patients and can have a significant impact on overall quality of life. By providing interventions that can be performed at home, investigator may alleviate these symptoms in hopes of improving the experience of patients undergoing Low Anterior Resection. By acknowledging these potentially debilitating symptoms in a systematic way, the investigator hopes to reinforce the importance of symptom management in the survivorship phase after treatment has been completed and ultimately facilitate an individual's return to routine activities.
The study aims to assess the existence of intraluminal malignant cells and the appropriate fluid volume needed to perform rectal washout during transanal total mesorectal excision (taTME) for rectal cancer.
Purpose: To assess the impact of taxes, warnings, and a combination of taxes and warnings on US adults' decisions to purchase products that contain red meat in an online grocery store. Procedures (methods): Participants will be recruited from Prime Panels (an online panel research company). Following online consent, participants will be assigned to one of four trial arms: 1) Control (no warning and no tax), 2) Warnings (all products that contain red meat have a health warning and environmental warning), 3) Tax (30% tax on products that contain red meat), and 4) Combined warning and tax (all products that contain red meat will have the two warnings and a 30% tax). Then, participant will enter an online grocery store reflecting their assigned arm. The participant will be instructed to complete a shopping task in the online grocery store. After completing the shopping task, participants will be redirected to an online survey and answer a series of questions about the shopping task, labels (excluding tax and control groups), and taxes (excluding warning and control groups). Questions will also include standard demographic and health related variables.
Understanding the quality of life and anorectal function changes in patients with middle and low rectal cancer after surgery can guide patients to recover after surgery and provide a valuable reference for surgeons in the selection of surgical methods. The purpose of this study is to: (1) Investigate the complication rate, recurrence and metastasis rate and survival of patients with middle and low rectal cancer. (2) QLQ-C30 and QLQ-CR29 questionnaires were used to assess the quality of life of patients with low- and middle-level rectal cancer at different periods after surgery. (3) Wexner constipation score and LARS syndrome score for anorectal function after operation for low rectal cancer. (4) The CIPE ejaculatory function score, IIEF-5 International Erectile Function Score, and FSFI-6 Female Sexual Function Index were used to assess the changes in sexual function of patients with low- and middle-position rectal cancer after surgery.
In a retrospective study, the investigators will compare patients with locally advanced rectal cancer with high risk factors for failure who were treated with standard therapy or with total neoadjuvant therapy.
this is a cross sectional intervention study to investigate the role of partial hydrolyzed guar gum in high stoma output management among cancer patients with ileostomy. This study hypotheses there is improvement in stoma output in PHGG if compare with control. There are two groups of subjects in this study. Conventional group (CG) will include retrospective historical data (those subjects with post-operative ileostomy) from Jan 2016 to June 2019. Intervention group (PHGG) will be subjects with ileostomy which involves prospective intervention by giving partial hydrolyzed guar gum upon start orally. Data on stoma output (volume & consistency), length of hospital stay, readmission within 30-days discharged and dietary intake will be recorded in data collection form.
The aim of the present study is to assess if it is possible to offer intersphincteric rectal resection (IRR) to selected patients older than 70 years affected by ultra-low rectal cancer. The study, involving patients with rectal cancer at less than 5 cm from the anal verge, will compare elderly patients refusing standard sphincteric demolition and undergoing IRR, with some control groups (younger patients undergoing IRR, >70 years old patients undergoing abdominoperineal resection + colostomy in left iliac fossa, >70 years old patients undergoing abdominoperineal resection + perineal colostomy). The groups will be compared in terms of quality of life, quality of life associated to incontinence, overall survival, disease free survival and post-operative complications. This will be helpful to identify conditions for extending IRR to elderly patients. The study is run by Colo-rectal Surgery Unit at Policlinico San Matteo in Pavia (Italy) from 2009 to 2016, directly led by Dr. Sandro Zonta (principal investigator) and funded by the hospital itself.
Treatment of patients with locally advanced rectal cancer (LARC) is multidisciplinary and consists of neoadjuvant chemoradiotherapy (nCRT) followed by surgical removal of the rectal tumor and potentially tumor positive lymph nodes. 1. After surgery, in 15 to 27% of patients that received nCRT no tumor cells can be detected during histopathological examination. In today's clinical practice, all of these patients with a pathological complete response (pCR) are operated upon, with substantial morbidity and mortality. The 5-year survival is 83.3% for patients with a pCR, and 65.6% for those without pCR. Response after nCRT is currently evaluated using magnetic resonance imaging (MRI). However, as MRI cannot differentiate between molecular characteristics of tissue, prediction of treatment response can be inaccurate. In patients with a potential cCR on MRI, additionally a high-definition white-light (HD-WL) endoscopy is performed with biopsies of the previous tumor location. If both MRI and HD-WL endoscopy confirm a potential cCR, patients can also be treated with a watch-and-wait approach, including frequent follow-up with HD-WL endoscopy and MRI. This potentially prevents extensive surgical procedures for patients in which this is not required. However, MRI and HD-WL endoscopy often remain insufficient for identification of cCR. Therefore, novel imaging methods are needed for accurate prediction of treatment response in order to select patients. The investigators believe fluorescence molecular endoscopy (FME) could be a promising technique for evaluation of treatment response. 2. During surgery, tumor-negative resection margins are of great prognostic value. Currently, surgeons rely on visual and tactile inspection for differentiation between malignant and healthy tissue. When in doubt, a frozen section can be obtained, which is time consuming and poses a high risk of sampling error. However, 14.7% of patients still have tumor-positive resection margins, increasing the risk of local recurrence and worsening outcome. Therefore, there is a need for novel imaging techniques that can be used intraoperatively to improve margin assessment. The investigators believe molecular fluorescence-guided surgery (MFGS) could be a promising technique for evaluation of resection margins.
