Active clinical trials for "Rectal Neoplasms"

This is a nonrandomised pilot trial to establish the role of intravenous cetuximab when added to a schedule of capecitabine plus pelvic radiation in patients who have locally advanced primary resectable rectal cancers.

The study outlines a clinical prospective protocol consisting of preoperative chemoradiation in locally advanced rectal cancer, without elective pelvic nodal irradiation. The proposal to exclude lateral spaces from the target volume is based on the assumption that the radiological evidence of recurrence in the lateral lymph nodes is shown to be below 5%. In the study all patients underwent an accurate pre-treatment work-up including total body CT, pelvic MRI and 18-fluorodeoxyglucose PET/CT, in order to include patients without evidence of disease in lateral lymph nodes. The primary endpoint of the study was the reduction of gastrointestinal toxicity; secondary endpoints were the pathological complete response (pCR), the local control (LC) rate, the overall survival (OS) and the disease-free survival (DFS).

This is a open-label, single-arm study to investigate the safety and efficacy of consolidative chemotherapy with camrelizumab, an anti-PD-1 antibody drug following short course radiotherapy and subsequent surgical therapy in patients with locally advanced resectable rectal cancer.

Multimodality treatment including surgery and radiotherapy is the current standard of care in locally advanced rectal cancer. Most clinical trials comparing short course radiotherapy (SCRT) with long course chemoradiotherapy(LCRT) did not find significant differences in oncological outcomes and short-term outcomes even though some debates. Recently, Stockholm III trial comparing SCRT plus delayed surgery with SCRT plus immediate surgery and LCRT demonstrated no differences with respect to short-term outcomes such as complications, mortality, and acute toxicity. However, overall quality of life (QoL) after curative treatment for rectal cancer is still major concern in both SCRT and LCRT. Furthermore, daily hospital visits for 5 weeks may be the cause of the increase of total medical cost due to indirect medical expense in patients with LCRT, especially in rural area. SCRT plus chemotherapy followed by delayed surgery may have the possibility of reducing total hospital costs as well as increasing QoL by proving non-inferiority in terms of perioperative outcomes. The present prospective single-arm phase 2 trial was designed to validate the efficacy, quality of life and cost effectiveness of preoperative short-course radiotherapy plus XELOX chemotherapy followed by delayed surgery for high-risk rectal cancer patient based on magnetic resonance imaging.

The objective of this pilot study is to assess the safety, functional outcome, feasibility and the potential benefits of synthetic mesh strip and gluteus flap reconstruction in perineum in case-control setting.

Near-infrared fluorescence-guided oncologic surgery (EGOS) with the use of a tumor specific tracer (SGM-101) developed by Surgimab can provide valuable intra-operative information about tumor location and extensiveness, which can be difficult to detect with conventional visual and tactile feedback. Hence, this information could aid in intra-operative decision making and therewith foster complete resection margins and less extensive surgery. Subsequently, this may drastically improve patient care by improving oncologic outcome.

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.

CSAR Trial's aim is to determine whether the transverse coloplasty pouch or the side-to-end anastomosis as rectal reservoir reconstruction offers the best functional results.

The purpose of this study is to evaluate the effectiveness of transanual tube placement in low anterior resection (LAR) for rectal cancer in preventing anastomotic leakage.

The Transversus Abdominis Block (TAP) block is known to be an effective means of reducing patient pain after abdominal surgery. In the meantime, the general TAP block has been studied in patients who were in the recovery room and the ward after surgery. The purpose of this study was to determine the effect of pain reduction and opioid saving effects in patients with TAP block in ICU settings.
