NCT03428529 | Completed Phase 2 DMC

• 1 other identifier: CEP INCA 83/10
• Study Type: interventional
• Target: 63
• Locations: 0 countries
• Sites: N/A

Brief Summary

A randomized two-arm study comparing preoperative CRT using oral capecitabine versus bolus 5-FU/LV concomitant to external beam radiation (50.5 Gy/28 fractions) for locally advanced rectal cancer. Main outcome was clinical response assessed using MRI and endorectal US 6-8 weeks after CRT. Secondary endpoints were pathological response, adverse effects, sphyncter preservation, quality of life, OS and DFS.

Conditions

Eligibility Criteria

• Age: 18 Years - 80 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients with histologically proven locally advanced rectal cancer (cT3-4 or positive regional lymph node) on endorectal ultrasonography (EUS) or pelvic Magnetic Resonance Imaging (MRI) were qualified for this study. Distance from anal verge (AV) should not exceed 10 cm measured with rigid proctoscopy. Thorax and abdominal computer tomography (CT) exams were taken to rule out distant metastasis. Performance Status ECOG 0-1.

You may not qualify if:

• Previous treatment for rectal cancer (RT, chemotherapy or surgical resection). Previous diagnosis of other cancers except nonmelanoma skin cancer. Uncontrolled comorbities including heart failure and miocardial infarction in the previous 6 months. Hepatic insufficiency and renal failure. Pregnancy. Serious neurologic or psyquiatric disturbances that could affect comprehension of informed consent.
