Filter by:This phase I trial investigates how well short-course radiation therapy followed by combination chemotherapy works in treating patients with stage II-III rectal cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as leucovorin, fluorouracil, oxaliplatin, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving short-course radiation therapy and combination chemotherapy may reduce the need for surgery and therefore improve quality of life.
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.
This study is a single-center, open, prospective, single-treatment trial (pilot study). This study aims to analyze the treatment results after receiving capecitabine adjuvant chemotherapy for 4 months after non-surgical treatment in patients who had completed and could have clinical complete remission with capecitabine preoperative chemoradiotherapy with capecitabine for mid-to-lower rectal cancer and to investigate the feasibility of non-surgical treatment.
Study design: A prospective phase II, non-randomized observational study of dose-escalated pencil beam proton therapy re-irradiation for pelvic recurrences from rectal cancer. Re-irradiation is either a part of neo-adjuvant treatment or as a definitive treatment strategy for un-resectable recurrences.
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 rationale of this clinical trial is to assess the feasibility of selective non-operative management for locally advanced rectal cancer using dose-escalated ultra-fractionated short course radiation therapy interdigitated with chemotherapy. We believe delivering short course radiotherapy over a prolonged interval, at escalated doses and with concurrent chemotherapy may be feasible and allow for improved clinical response.
Short-course radiotherapy followed by consolidation chemotherapy has shown a better response rate when compared to chemoradiotherapy treatment. In addition, recent studies have shown better tolerance with total neoadjuvant treatment, with induction or consolidation chemotherapy. Induction chemotherapy could reduce the size of the tumor, treat micrometastases early and allow treatment to start immediately (avoiding potential delays in waiting for radiotherapy). While consolidation chemotherapy allows longer waiting times for surgery, with higher response rates.
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.
Total mesorectal resection (TME) is the standard surgical method for locally advanced rectal cancer, which significantly reduces the local recurrence rate. However, the incidence of urogenital dysfunction is higher. Studies found that Denonvilliers' Fascia contains autonomic nerves that may regulate urogenital function, while traditional TME surgery resects part of it. Recent Studies found that complete preservation of Denonvilliers' Fascia could improve urogenital in selected patients with rectal cancer. Locally advanced patient (T3-4 and/or N+, M0) accounts for a high proportion of mid-low rectal cancer. However, whether these patients can benefit from it has not fully been demonstrated. This project conducts a multi-center randomized controlled study to evaluate the effects of complete preservation and partial preservation of Denonvilliers' Fascia on postoperative urogenital function of locally advanced non-anterior mid-low rectal cancer.
