View clinical trials related to Rectum Neoplasms.
Filter by:Neoadjuvant therapy has been widely applied to locally advanced rectal cancer. However, about 50% of patients receiving this therapy do not respond well as evidenced by the fact that their T or N stages are not effectively decreased judged by postoperative pathological examination. The purpose of this trail is to identify the biomarkers (from within patients' tumor mass before neoadjuvant therapy) to predict resistance to neoadjuvant therapy. These biomarkers can help stratify neoadjuvant-resistant patients towards surgery while avoiding unnecessary chemoradio-based neoadjuvant therapy.
The purpose of this research study is to look at how tumors responds to a short course of radiation (5 days) followed by 8 cycles of chemotherapy.
TME (Total mesorectum excision) is the golden standard of radical resection for mid-low rectal cancer. However, the damage of pelvic autonomic nerve following with TME principle will lead to high incidence of urinary and sexual function disorder. Open PANP (pelvic autonomic nerve preservation) TME surgery played a role in decreasing incidence of urinary and sexual function disorder. However, 32%-44% patients still suffered from urinary and sexual function disorder when underwent Open PANP TME surgery (O-PANP-TME). Laparoscopy-assisted TME surgery (L-TME) is applied wildly nowadays. In the early stage of work, we performed laparoscopy-assisted PANP TME surgery (L-PANP-TME) to discuss the protection of urinary and sexual function of male mid-low rectal cancer patients. The results showed that L-PANP-TME significantly decreased incidence of urinary and sexual function disorder. In order to further confirm our early work, we design a multiple-center randomized controlled clinical trial to compare differences in urinary and sexual function protection and long-term outcomes between L-PANP-TME and O-PANP-TME.
